Time has really passed too fast, and the internship life of more than two months is over. When I understand the characteristics of each student and start to build relationships with them, I can’t get along with them anymore, although together Not very long, but I feel that I have learned a lot. It made me really appreciate the fun and hard work of being a teacher. At the same time, it turned the theory I studied in the classroom into practice, making virtual teaching a real face-to-face teaching. Of course, this also exposed many of my shortcomings. A short internship life, I feel good. When I walked on the internship campus, there were students who shouted "teachers are good" and "teachers are good". This feeling is really good.

Since Hankou Iron and Steel is an art high school, it is not like art appreciation classes in other middle schools. Art time is drawn in sketches, colors, and sketches. Every day, it is to help students change their paintings, correct their sketching assignments, and have few opportunities to attend classes. However, as a pilot of the new curriculum reform, Wuhan has fully rolled out various experimental activities. This time, I happened to run into the art class competition in Jiang'an District. The art teacher in the iron group concentrated on an exercise. This is a rare opportunity to attend classes, so I joined the ranks of the lecturers. Watching the teachers sway in the classroom, the students can be deeply attracted by the language of the teachers, and under the guidance of the teacher, they can deeply understand the content they have learned and actively cooperate with the teacher to make the classroom atmosphere very harmonious. envy. At the same time, my heart is also thinking: When will I be able to reach their level? After one month of internship, I have to teach a class because of the teaching ability test, so I went to the professional teacher and class teacher of my class. Ask for the lecture. The class teacher and the professional teacher all expressed their full support. The next step is to start preparing lessons. The lesson is not simply to read the textbooks, but to carefully sort out the contents of the textbooks and try to express them in their own language. This process of retelling alone has already tested our ability. Although we all have a good subject knowledge base, it is quite a headache for me to describe the simplest subject knowledge in a common way. For the teacher, the biggest doubt should be "how much the teacher should teach." I used to take lectures as a student, and the purpose was to learn knowledge. Now, as a teacher, I am studying for students. The purpose is different, our attention is different. When I first read the textbook, I felt that I had to say a page of books in 45 minutes. Later, I prepared a class and found that there were many problems to explain. It was very good to have a few pages in one class. Perhaps the more you know, the more difficult it is to start. Due to the lack of experience, we have not done a good job in dealing with the teaching materials and grasping the content of the lectures.

I finally got to the podium. When I walked onto the podium with shame and sorrow, I made a lot of preparations, but when I really faced so many eyes, I was still nervous. Although I have repeatedly stressed myself to smile before I go to class, I want to relax. But when I really "strike the battlefield", I have already thrown my own shackles out of the clouds. I don’t know what expression I was at the time. My classmates said that I can Rescuing the students, the teacher also said that I am very skilled, very teacher-like, I do not know that I was calming down the predecessor „„ Sure practice of truth, in the classroom, my shortcomings are undoubtedly exposed. Although the whole class is still relatively smooth, the time is just right. However, there is still a lack of content in the course, which fails to highlight the difficulties and has no depth. The questioning method is not flexible enough, the board is not beautiful enough, and so many problems have appeared. But I am still very happy, so I will have a direction to improve in the future. Train your deficiencies. Forming the characteristics of classroom teaching with "problem-driven, first-school learning, and timely training", and strive to do: to set the doubt as the guide; to use thinking training as the core; to reveal the law as the focus; to concentrate on the refinement as the strategy; Student participation as a pathway; aiming at holistic teaching. Continuously improve your professional skills and teaching skills.

During the internship, although I listened to countless "teachers", I still had a happy smile when I responded. When standing on the podium and being stared at by a pair of pure eyes, the sense of value and accomplishment as a teacher came into being. During these two months, although many students have been helped, some students have improved their grades. But I have not done everything, there are still many shortcomings. It is also impossible for all students to like me, but as long as most of the students remember me, then my internship has a bright spot that is hard to eradicate.

During the entire internship, I felt that the work of the class teacher was the most memorable. During this time as a class teacher, I had more contact with the students. This class belongs to the art class. There are 59 students in the class. There are more women than men and only 14 boys. Therefore, boys are “vulnerable groups” in this class and are often “siege” by a group of girls. Most students have the enthusiasm and consciousness of learning. Classmates help each other, the sense of collective honor is strong, and the class develops harmoniously. A small number of students are unstable and have a feeling of being tired of learning. Boys are smart but lazy, girls are diligent but their rational thinking is poor. The overall grade of the class is not bad. The first week is a trainee, mainly to see how the class teacher manages the students, understands the duties and due diligence of the class teacher. And develop a class teacher's work internship plan to ensure that the class teacher's work internship goes smoothly.

As the director of the internship class, the original class teacher should be assisted in educating the students on various aspects of ideological and moral character, learning purpose, health, etc., improving the students' academic performance, and organizing the whole class to become a strong collective of unity and friendship. During the class teacher's class, I will go to the playground every day to urge the students to do exercises, and care about the students' physical and mental development and healthy growth. Cooperate with physical education teachers to take good physical education classes, organize students to participate in extracurricular cultural and sports activities, and enhance physical fitness. At the end of September, the internship school will hold the school autumn games and the school chorus festival. I assisted the original class teacher to organize and plan the entrance ceremony of the sports meeting, and use the spare time to supervise and guide the students to train. Every day during the lunch break, they will practice chorus with the students and lead the students to participate. In the chorus preliminaries, because one of the lead singers suddenly forgot the lyrics and made a little problem, the overall result is good. During the sports meeting, I was arranged to count the results at the check-in office. If I didn't stay overnight, I would take time to go to the class to maintain discipline. Share the good results they have achieved with the students. After the end of these two events, it is the 11th holiday. Because the internship school is relatively tight, only two days off. As a teacher of the internship class, I should take classes with the students to help them improve their academic performance. After that, I returned to normal working hours. Every day at noon, I urged students to take a lunch break in the classroom to maintain discipline and provide students with a good rest environment. The second important task of the internship teacher is to carry out the theme class meeting. In the past class meeting, we all acted as an audience. Now suddenly letting me carry out the theme class will make me feel like a duck. First of all, the important part of the theme class meeting is to design a set of good theme class meeting design. The second step is to develop the design plan according to the theme. The class theme should be set according to the student's learning situation and psychological changes, and morality should be set for them. Quality education. After contacting them for a while, they found that these students are independent and self-centered, probably because they are all “90s”, most of them are only children, they grew up in the love of their parents, many students I don’t know my parents’ birthday, and I accept the care of my parents. Therefore, I organized a class meeting with the theme of “Grateful Parents”. The purpose is to stimulate students' understanding of gratitude and to understand the hardships of their parents during their growth. Play is a human nature, not to mention the students who are in adolescence, some students are too playful, especially boys, often the teacher does not pay attention to slip out to play games, or play mobile phones during school hours, read novels. Even some students with poor grades think that teachers don't like poor students, don't care enough about them, give up on themselves, and even deliberately disturb to attract the attention of teachers. For this part of the students should be patient and meticulous in individual education, change their thinking, and give them more guidance in learning, to eliminate their inferiority. Transfer interest and lead the way. After the individual education of several students, they found that they did change, and they were able to ask the teacher for questions that they did not understand. They also exchanged learning experiences with good students. This also proves that the work I do is meaningful. As a teacher, I will be angry because the students are not studying hard, and they will be happy because of the little progress of the students. I think this is the sacred place of the teacher profession.

Grasping daily work and strict routine management are also one of the things that can not be ignored in the work of the class teacher. Every day, I will go to the class to understand the class and study situation, supervise and inspect the students to do a good job in learning, discipline and health, and carry out ideological education and study guidance anytime and anywhere to handle the daily affairs of the class.

Finally, I will talk about my feelings about the internship experience of this class teacher. First of all, I realized that there must be three head teachers. The first is to have a sense of responsibility. To have a heart that is responsible for the class, to focus on the class, always think about the class, and second, to have a sincerity. The heart, the class is like a big family, the classmates help each other like brothers and sisters. If you want to be a class teacher, you have to integrate into this group. Only with a sincere heart to treat each student. Be one of them. The third is to have a career, as a class teacher, if you want to be qualified for this position, you must first have the ability to survive in the competition. The internship teacher also sounded the alarm for me. During this internship, I found out that I have many deficiencies, such as the lack of place in the management of the class and the organization of the class. The experience of this internship will be my precious wealth and provide experience for my future education work. I am convinced that I will be able to handle it in the future work, because the experience of this internship teacher gave me great confidence.

Internship is like entering a social melting pot. Although Qian Tao Wan is hard, even if he is tempered and bruised, he must be geared up and ready to join the furnace again. Hankou Iron has witnessed our growth and witnessed the process from our youth to maturity. I gradually became "confident and brave" in this internship.

Internship, accompanied me to experience setbacks and also experienced joy! In this short two-month internship, I feel deeply that "preaching, teaching, and confusing" is a long-term and a long-term thing, and we need every A person who loves education works hard together and struggles. In short, all the way, all the way to gain, in this process, I always let myself be careful, open-minded, sincere--internship and management, humbly to the class teacher and guidance The teacher learns and treats every student in the class sincerely. Of course, teaching is a very profound art. Therefore, "the road is long and the course is long, I will go up and down." I will continue to learn and keep improving!

Part 2: Summary of production internship

I studied architecture, so during the summer vacation, I came to Yingkou Xingyu Construction Engineering Co., Ltd. for an internship. I was a technical person in charge. I want to expand my knowledge through contact and participate in practical work. I can deepen my understanding of the theoretical knowledge I have learned in the classroom, improve our ability to connect theory with practice, analyze problems and solve problems. At the same time, we can learn and train through the construction site. Cultivate our excellent quality of hard work, modesty and eagerness to learn, and promote the all-round development of our moral, intellectual, physical and aesthetic development, and lay the foundation for us to become a qualified engineering construction talent in the future. When I first arrived, I treated myself what I saw and heard as a beginner. When you enter the construction site, you must bring a helmet. The workers under the heat of the summer are still working tirelessly. Whenever you see such a picture, there is always some feeling in your heart. The supervision work is to supervise the construction of the construction party during the construction period to ensure the quality of the project. The process of patrolling the site every day with the teacher is my chance to learn.

The construction basis of the construction party is the drawings, and the basis for the supervision supervision construction quality is also the drawings. In this practical activity, I came into contact with two kinds of drawings, namely architectural drawings and structural drawings. Architectural drawings are the most and the earliest drawings after going to college, so they are more familiar, and the structural drawings have never been touched. When encountering problems that I don't understand, I will be open-minded. However, the representation of the drawings is too abstract after all. If you want to understand more concretely and deeply, you must have deep professional knowledge. This has strengthened the determination to learn professional knowledge.

During the half-month construction internship, I carefully reviewed the structural construction drawings and construction drawings of “Zhongtian Shangpin 3# and 5# Buildings”; participated in the operational internships of measurement engineering and steel engineering;

The project is the Zhongtian Shangpin 3# and 5# residential buildings built by Yingkou Xingyu Construction Co., Ltd. The first floor of the project is set up on the ground floor, with 28 floors above ground, with an indoor and outdoor height difference of 300mm and a house height of 82.200m. The design elevation of ±0.000 is equivalent to an absolute elevation of 3.000m. The structural form of the project: the main building is a reinforced concrete shear wall structure with a seismic grade of two. The safety level of the building is two. The design life is 50 years. The seismic fortification intensity of the building is 7 degrees.

Practice knows the truth, but it is undeniable that there will be many problems in the process of knowing the truth. Although the production internship is generally successful, there are also some problems, which are summarized as follows: poor hands-on ability, lack of theoretical connection and practical ability.

In the field production internship, I have always felt that my ability to do things is poor. When measuring the line, the master can quickly adjust the instrument in one or two minutes, but it takes more than ten minutes. This has a lot to do with the lack of opportunities for practical exercise. In the internship, the teacher has been emphasizing the connection between theory and practice, but the key is how much theoretical knowledge is there. In the only theoretical knowledge, how much can be related to reality? The reason is that our ability to adapt is not strong, learning Not deep enough

A few days after I first arrived at the construction site, after a sudden sense of freshness, I suddenly felt at a loss. Coupled with the rainy days that have been going on for a few days, there is not much to do while staying at the construction site, and my heart is inevitably a bit boring. During the period of returning to the internship, I feel that my attitude and attitude are crucial. These often determine the success and success of the internship.

As a student, we must overcome the impetuous and complacency in the internship at the construction site, learn from the master humbly, and adjust the mentality. If we can calm down and learn, we will certainly learn a lot of things. My experience is very deep.

First of all, the biggest gain of this internship is to learn to adapt to the environment. Although it is not necessary to go to work on the construction site in the future, but with this period of exercise, no matter what work is done in the future, there is a kind of perseverance that bears hardship and endurance, and also learns to adapt to the environment. In addition, I knew some problems on the construction site that were different from the school. I knew on the construction site how to be a technician and how to communicate with the workers.

Secondly, through this internship, I have gained a deeper understanding of the relevant knowledge of engineering. It should be said that learning more professional knowledge at school is only theoretical, and it is still somewhat different from reality. This internship has some help for my ability to map and map. I know where to pay attention and calculate carefully. Where the structure must consider the safety of the construction, and where to consider the actual construction problems when drawing. It can be constructed and meet the requirements of the specification, and the design and construction standardization can be achieved. Without this internship, perhaps the drawing is just a photocopy of the book, not considering too many problems, and even more likely to think about whether the design can be constructed. Although the construction site is bitter, what can be learned is some practical things. The exercise is the practical ability to solve problems.

It’s been a few days since the end of the internship. At this moment, I think that the days I have walked through will not be overemphasized. Although the internship time is only a short half-month, I have learned a lot from both academics and personal life. Many things, such as doing more things, talking less, and doing what you should do well. By studying these, I also have a clearer understanding of my future work and development, and I have determined my determination to fight for my goals in the future. University life is a day of intense and full of expectation. When you are studying leisurely, you always carry your bags, stay away from family, friends, and teachers, and go to the road of your own. However, when we finally can leave the nests of the elders like the eagle feathers that have just been feathered, and walk alone on the big stage of social work, we find that the road to life is so rough and bumpy, anyone’s success is It was a storm. This is the first time in my life to enter the society, the first time I went to work, I feel that life is really not easy. In short, I believe that this valuable experience will make my future growth path more stable and more solid.

Part 3: Production Intern Summary

In the past summer vacation, we have carried out an important practical process in the undergraduate stage, that is, production internship, although there are only ten days, but I have gained a lot.

In the previous study life, the source of knowledge was often limited to textbooks and teacher explanations. It is also very abstract to understand a lot of things, and through this observation of the first line of production and the introduction of the relevant workers, we have a relatively intuitive understanding of the production of the basics of this profession. There are even things that we think are simple, but in a specific production it is another situation. This is a test of the sentence on the upstairs of the school's experiment: "The paper has to come to a close, I know that this matter must be carried out." Let me talk about what I have seen and heard in this internship experience.

The destination of our internship is Luoyang, which is known as the “Millennium Ancient Capital, Peony Resort”. This is a city with a fairly developed industry, and many well-known companies in the machinery industry are located here. I am very excited to be here for an internship. On the afternoon of July 17, we arrived at the main internship location ------ China's first tractor manufacturing plant. This is a historic old company, and the great statue of Chairman Mao at the door can explain this.

China Yituo Profile: In 1955, as one of the 156 key construction projects during the “First Five-Year Plan” period in New China, Mr. Mao Zedong’s instructions showed that China’s largest tractor manufacturer, Yituo, broke ground in the Luxi District of Luoyang. After three years of perfect construction, on July 20, 1958, the first tractor was towed off the assembly line. On November 1, 1959, one trailer was officially completed. Up to now, China Yituo Group Co., Ltd. has more than 17,000 sets of equipment. More than 40,000 employees, listed in 1997, the company implemented total quality management. "Oriental Red" became China's first mechanical well-known trademark. Their "Dongfanghong" series products have been exported to more than 50 countries and regions, and have strong product development, process and tooling design capabilities. And has passed the China Quality Association ISO9001-2000. The internship officially started on the morning of July 18. We did not go directly to the factory, but did a safety education in the classroom of the internship reception center. This seemingly formal thing is particularly important in the bloody facts, and any factory must put safety production and the lives of workers first. Every worker who is about to enter the factory must undergo a strict safety assessment. The safety hazards in the factory are mechanical hazards, chemical hazards, and explosion hazards. Thermal hazards, electrical hazards and other hazards. Therefore, before entering the factory, you must: 1. Wear labor insurance products according to the regulations, do not wear slippers and sandals; 2. If the running equipment is not allowed to cross, it is not allowed to stand in front of the rotating objects and the chips may fly out. Parking before the guard; 3, when repairing the machinery must hang the warning sign at the power switch, who hangs who picks; 4, all electrical exposed wire can be connected to zero maintenance materials insulated and reliable; 5, pedestrians make channels, do not cross the danger zone Do not stop under the hanging objects. In addition, I also learned several safe colors, red forbidden to stop, blue for instructions and compliance, yellow for warning, green for traffic and safety. This is very helpful for our future internship visits.

The first factory we came to was the engine one branch, which was divided into several workshops, such as machining workshop, parts workshop, assembly workshop, and test workshop. The engine plays a pivotal role as a power component for the operation of a mechanical device. In the machine shop, the main production of engine key components, from the blank to the finished product are formed by a complete production line, which is divided into multiple processes, each process only needs to process several specific faces or holes, generally First and rear holes, larger parts such as box parts are fixed on a conveyor-like mechanism, and each process is completed by the slow movement of the conveying mechanism. This not only ensures the processing speed but also facilitates the mass processing of the product. After the processing is completed, I saw that the workers will take out some of the parts and use them with precision instruments such as micrometers. If they do not meet the requirements or the size is too large, they will be processed twice. In the assembly line, the entire production line uses a large chain sprocket with a hanging chain. An engine can be sold on the basis of a qualified test.

The first assembly plant is a manufacturer of crawler machinery and its variant products of China Yituo Group Co., Ltd. It mainly produces three series of Dongfanghong 40-60 horsepower crawler tractor, Dongfanghong hydraulic excavator, Dongfanghong 100-130 horsepower transporter and agricultural wheeled tractor. It is the only crawler tractor manufacturer in China. base. After more than 40 years of development, Dongfang Red-brand tractors and construction machinery are spread all over China's provinces and autonomous regions and exported to more than 50 countries and regions such as Europe, North America, South America, Africa, East Asia and the Middle East, and are well received by users. In the past ten years, 15 major skill reform projects have been realized, involving cold, hot, coating, loading, welding and other process links, and a new assembly line has been built. The degree of process equipment and production capacity have been further advanced, and the competitiveness of enterprise products has been strengthened. The factory has nearly 1,000 sets of modern equipment, including flexible processing lines in the processing center. The first assembly plant also has the ability to improve, develop and sell various new variants of tractors. It has more than 100 middle and senior technical personnel, and can adapt to the development and changes of the international and domestic markets and the different needs of users. A complete large tractor production line can be seen here. It consists of six large stations: engine station, drive wheel station, trolley station, water tank station, diesel tank station and frame station. , China Oriental Red Tractor was born here. In this factory, we are fortunate to have read some of the drawings and materials here with the efforts of the team leader. These drawings are all from the 1950s and 1960s. The machining process for each part is an atlas, each of which shows its machining position, size and surface accuracy requirements. The top page of each atlas is marked with the process number, the process name and the corresponding machine tool model, and the last leaf is the specific schedule. Although the drawings are hand-painted, they are all very beautiful and worthy of our engineering students. As an electromechanical student, you should not only have a solid knowledge of natural science, but also a rigorous scientific attitude. It is also worth mentioning that as a large enterprise, having a profound corporate culture is essential. Corporate culture symbolizes the soul of a company, and each branch has its own corporate culture. The “5S” management mode is written on the walls of a loading plant and engine factory, that is, finishing, rectifying, tidy, cleaning, and literacy. They are sorted out: distinguish between necessities and non-essential items, and do not distinguish between non-essential items on the spot; rectify: reduce the time to find necessary items to 0; neat: keep the post in a state of no garbage, no dust, clean and tidy; cleaning: will organize and rectify Clean and tidy; literacy: consciously obey the implementation of the prescribed things. What is 4R? R1: The definition of the result is clear; R2: one-to-one responsibility; R3: Do not believe anyone; R4: System implementation points. These scientific management models have undoubtedly played an important role in the processing of products, reducing the rate of scrap. This is closely related to the course “Total Quality Management” that we studied in the last semester, and it has been fully applied here.

On the afternoon of the 20th, I went to Fuel Injection Co., Ltd. It originated in the fuel plant in 1955. Its main product is the production of oil pumps, the main function is to convert low-pressure oil into high-pressure oil, providing fog-like diesel fuel for the engine because the fuel has a relatively high ignition point between 220 °C and 240 °C. In addition, there are three important parts: camshaft, thrust disc, and lower body. During the visit, I saw three lines in the main processing workshop. Processing process of camshaft: 1, center hole 2, right outer circle 3, axle neck 4, left outer circle and cone 5, right outer circle 6, fine cam surface 7, heat treatment 8, grinding Finishing process. Because the shape of the cam itself is special, it is processed by a contouring machine, similar to the process of keying. It should be noted that the difference between turning and grinding is that the position of the shaper is different, the former is mounted on the tool and the latter is on the workpiece. The main processing process of the lower part of the oil pump: 1, rough milling upper 2, drilling 3, 镗 left and right holes 4, boring 5, drilling front hole, milling front hole 6, milling hole 7, positioning with 4 holes, milling The front, rear, left and right faces 8, with the four holes as the reference, the left and right holes 9, the chamfers 10, the drill holes 11, and the tapping. In addition, there are two not too big but important two parts, the sprayer coupler and the plunger pair, which are processed in the special processing field. Later, after the introduction of the professionals, we know that the plunger and the plunger sleeve are clearance fit, and the gap is only 2 to 3 nanometers, so there is a high requirement for the surrounding environment and processing equipment. This gives me a new sensory understanding of some of the new processing methods.

We have seen a lot of general-purpose machine tools in school, and here we have the opportunity to see a lot of special machine tools. The next factory we visited was the gear factory. This involves a variety of processing methods for gears, as well as many special tool machines for machining gears. Important equipment includes radial drilling machines for deep hole machining of parts, bench drilling machines, vertical landing gear milling machines, semi-active spline shaft milling machines, gear hobbing machines. , horizontal rectangular table surface grinder, multi-tool lathe, straight tooth bevel gear machine, electric control cabinet and other various machine tools. Arc tooth big wheel precision cutting machine, machine tool active chip conveyor, slotting machine. The main products are spur gears, helical gears, straight bevel gears, spiral bevel gears, involute splines and rectangular splines. We have already contacted the hobbing machine hobbing and milling machine milling methods, and there are other methods for gear machining: the inserting teeth of the inserting machine can process the internal teeth, and the gear shaping machine, the shaving machine is the finishing of the gear. These methods are intuitive to understand their processing principles. At the same time, the gear factory also introduced some numerical control equipment. Here, there is a 210H gear hobbing machine purchased last year that attracts the attention of many students. It automatically feeds the finished workpiece into the machining center and processes it after a short time. It can be seen that the use of a CNC lathe is not only easy to operate, but also highly efficient. He is a trend in the future of mechanical manufacturing. In the later gear lecture, I had a clear understanding of the process of gear processing. The gear processing flow is 1, material inspection 2, blanking 3, forging tooth blank 4, tooth blank processing 5, tooth shape processing 6, end chamfer 7, tooth shape finishing 8, processing spline, keyway 9, cleaning and cleaning 10, gear precision inspection 11, heat treatment 12, cleaning gear 13, finishing surface finishing 14, heat treatment after tooth finishing 15, strong shot peening 16, phosphating 17, cleaning and cleaning 18, finished gear pairing test and final test.

The third assembly plant of First Tractor Co., Ltd. is the main engine factory for the production of "Dongfanghong" high-power series wheeled tractors. It has the most advanced assembly line in the agricultural machinery industry, and the important stations are equipped with manipulators. The ERP system used can minimize inventory based on customer requirements and priorities. The MPS system can also distribute parts to the production line. The Dongfanghong high-power series wheeled tractors produced by the three-package factory have powers ranging from 60 to 200 horsepower, and more than 20 basic models and more than 200 optional variant products. Among them, 70-90 horsepower series wheeled tractors are produced by introducing international advanced technology; 100-120 horsepower series wheeled tractors are developed on the basis of digestion and absorption of foreign advanced technology; MG series and 16-180 horsepower The series of high-power wheeled tractors are technological innovations independently developed by Yituo Group. The factory is very clean and has a high degree of automation, which fully demonstrates the new vitality and vitality of an old factory.

Finally, we have learned some advanced manufacturing techniques at CITIC Heavy Industries. CITIC Heavy Industry is one of the 156 key projects built during the first five-year project in China. After half a century of construction and development, it has become one of the largest mining machinery manufacturers in China and one of the largest heavy machinery manufacturers in China. It is China's low-speed heavy-duty gear processing base, central and southern region casting and forging and heat treatment center, national-level physical and chemical inspection and approval unit and national first-class measurement enterprise. We are fortunate to have seen the world's largest carburizing furnace, as well as Φ12m heavy-duty double-column vertical car, the largest processing diameter of 12000mm, the maximum processing height of 3500mm, the maximum processing weight of 150t. Just in the factory, we came across a truck carrying half a giant gear. According to the master, it is half a gear with a diameter of 12m. The parts processed here are bulky. For the convenience of transportation, only half of them are processed, called 1/2 parts. When I reach the destination, I use bolts to connect them. This really opens my eyes. These oversized parts are mainly used in mining machinery.

The ten days of staying in Luoyang are short and full, short because the mechanical knowledge contained here is really too much. It is not a matter of one or two years to really understand these things, but we still learn a lot of books. Foreign knowledge. Many processing methods, while theoretically feasible, still have to consider many factors in practice. In short, this internship experience has enabled me to have a more comprehensive understanding of the production organization and production process of machining, to understand and master the practical knowledge of the basics of this profession, and to consolidate and deepen the theoretical knowledge that I have learned. Through the analysis of the machining process of typical parts such as crankshaft, drive axle, and the machine tools and fixtures used in the machining of parts, we have improved our work of combining theoretical knowledge and practice to analyze and solve problems. ability. I would like to express my gratitude to our team leaders who have not only worked hard to lead us in the internship, but also made great efforts in their contact with the unit, which made our internship complete successfully.
