Car maintenance internship summary

Part 1: Summary of student auto repair internship

In March of this year, the school arranged for us to go to Ankang Hongda Auto Repair Factory for an internship. My internship time was 4 months. I was intern in the repair shop with auto mechanic technology. I learned a lot from this internship. Further understanding of the basic structure and basic knowledge of the car, enhancing the ability to actively face and overcome difficulties and hard work, laid a good foundation for future adaptation to work, and further stepped into the threshold of the auto repair industry. .
During the internship, I mastered the standard methods of using, maintaining, adjusting, installing and other related technologies for the engine, chassis, body and electrical equipment of the car. I also learned about the vehicle inspection and maintenance system; I was familiar with the various parts of the car and mastered it. It is very important for each of us to get to the use of inspection tools; some simple skills for fault diagnosis and elimination of various systems in the car. It is much easier to combine practice and theoretical knowledge we have learned. I can learn this major well. In short, although the internship is boring, I have learned more techniques.
During the internship, the master told us that in order to learn this major, we must have strong practical skills, so we must be diligent in hands-on, skilled operation, and practical mastery of practical skills. At the same time, we must be diligent in thinking, good at combining the learned content with the actual, combining with production, connecting with life, and constantly summarizing and summarizing, and gradually cultivating the ability to make a difference, so that we can become a qualified technical ability talent. This major is good.
I learned a lot of knowledge during this internship, and I will not list them one by one. However, I know that doing this line requires real technology, and we must not be afraid of hardships, not afraid of dirty, in order to become a real technical talent, in order to really do this.
I saw the master dressed in oil, my hands were black, and I went from morning to night, so hard, I was a little retreating, but we chose this major, we must do it well. Confucius said: "Three hundred and sixty lines, the line is the champion." No matter what work is not easy and simple, how can I do it without suffering? In the internship, I understand that I only have to ask the experienced master for advice, and I can do more work and brainstorming to do the job well.
Although we had a short internship at this auto repair shop, I learned a lot of the technology I wanted to learn at this repair shop. Although I thought about giving up in the middle, I still insisted that the time for internship at the repair shop has passed for a long time, but now I still remember it as if I was just finished, now I am right. The car repair industry has generated great interest, which will play an extremely important role for me in the future.
Thanks to the school, thank the repair shop, they gave me the opportunity to internship, let me like the car repair industry.

Chapter 2: Summary of Auto Repair Practice

In July 20xx, I conducted an electrical internship at the Dongfeng Citroen 4S store. During this year, I have a certain understanding and deep understanding of the vehicle sales, parts supply, after-sales service, maintenance and information feedback of the car repair service station.
Dongfeng Citroen Sales & Service Co., Ltd. is a first-class maintenance equipment with Dongfeng Citroen's fixed-point and direct supply: lifting machine, tire dynamic balancing machine, body calibration frame, paint booth, etc., used in the maintenance business computer network. Spacious, tidy business reception hall, spacious maintenance workshop, 24 standard workstations to meet the needs of maintenance operations. Complete specifications, high-quality and pure accessories are the safety guarantee for the operation of Citroen series vehicles. Dongfeng Citroen Sales & Service Co., Ltd. is a large four-seat store with sales models including Fukang, Elysee, Saina, Sega, Sarah Picasso, Triumph, C2, C4, C5, and a total of nine models.

2. Familiar with the car repair environment and repair tools. Accumulate certain knowledge and experience for coming to work in the future
3. Open up our horizons, enhance professional awareness, and consolidate and understand professional courses.
4. Through the on-site maintenance internship and the exchange guidance of the employees, the theory is linked with the reality, the theoretical knowledge learned is verified, deepened, consolidated and enriched, and the ability to analyze and solve practical problems of the project is cultivated, which is the learning and curriculum of the subsequent professional knowledge. Design and graduation design lay a solid foundation.
wiring
The more expensive the car is now, the more complicated the electronic control part is, and the more sensors there are, the more complicated the line is. Pay special attention to the direction of the installation and the purpose of each harness when installing. Otherwise, the wiring harness will be too short or too long. This requires the car mechanic to be very familiar with the route of the car. Pay special attention to the characteristics of the size, hole position and color of the two plug holes when connecting the connectors.
Instrumentation and workbench
The circuit of the instrument assembly is a modern integrated circuit, and only the corresponding plug needs to be inserted thereon. Air conditioning air volume control port, negative driving position air bag and bracket for fixed workbench should be installed on the workbench.
Internship harvest and summary
In general, this internship gave me two aspects of the harvest: the adaptation and socialization of the work environment; the combination of theory and practice.
From the beginning to the repair shop, the smile of my own master gave me a good start. In the whole internship, except for a few special circumstances, I went to work every day, got off work, and often participated early. Yes, it is more harmonious with most of the masters.
This production internship gave me a valuable life experience. I have a more detailed and profound understanding of my major, and it is also the consolidation and application of the knowledge I have learned in colleges over the past few years. In the internship, my theory is in real contact with practice, and there is a combination of thinking and reality. These have played a role in my concept or subtle or shocking. From this internship, I realized that the actual work and the knowledge in the book are at a certain distance, and further study is needed. However, this short three-week internship is far from being able to understand an industry in depth, and to improve the professional skills. What you have learned is superficial and rough.
During the internship, I also had a clean understanding of my many deficiencies: I was not doing enough things to be steady and steady, and there was a lot of room for improvement in social skills. Professional English was not solid enough.

Part 3: Summary of Auto Repair Practice

"Time is like an arrow, the sun and the moon are like a dragonfly." In a blink of an eye, time slips away from the hand. During this one-month internship, I realized a lot of things; at the same time, I felt very deeply about me; it laid a good foundation for my future study.
During the internship, I mastered the standard methods of using, maintaining, adjusting, installing and other related technologies for the engine, chassis, body and electrical equipment of the car. I also learned about the vehicle inspection and maintenance system; I was familiar with the various parts of the car; The use of inspection tools; some simple skills for troubleshooting and troubleshooting of various systems in the car.
Internship is very important to each of us. Through the combination of practice and the theory we have learned, it becomes easy to understand, and we can learn this major. In short, although the internship is boring, I have learned more techniques.
During the internship, the master told us that in order to learn this major, we must have strong practical skills. Therefore, we must be diligent in hands-on, skilled operation, and practical mastery of practical skills. At the same time, it also requires diligent thinking, is good at combining the learned content with the actual, combining with production, connecting with life, and constantly summarizing and summarizing, and gradually cultivating the ability to give inferences. In this way, we can become a talented person with qualified technical ability to learn this major.
I learned a lot of knowledge during this internship, and I will not give it a single example. However, I know that doing this line requires real technology, and we must not be afraid of hardships, not afraid of dirty, in order to become a real technical talent, in order to really do this.
I saw the master dressed in oil, and my hands were black. From morning to night, it was so hard, my husband was a little shrinking. But we have chosen this major, we have to do it well. Confucius said: "Three hundred and sixty lines, the line is the champion." No matter what work statistics are not easy and simple, how can you do it without suffering! In my study, I understand that I only have to be open-minded to the experienced masters, and I can do my best by doing more work and brainstorming.

Chapter 4: Car Maintenance Internship Summary

I am doing a maintenance internship at xx Ltd. In the course of more than a month, I have a car maintenance service station, parts supply, after-sales service, maintenance equipment: lift, tire dynamic balancing machine, body correction frame, paint room, etc., also have a conservative Export testing instruments: x431 computer tester, ignition tester, etc., and computer network used for maintenance business.

The conception and graduation concept lay a solid foundation.
5. Maintenance internship is the training and training of Mr.'s analytical ability. Throughout the internship process, he fully mobilized Mr.'s objective initiative, deepened meticulously and carefully observed and theoretically, and made his own hands-on ability progress.
Second, the internship content:
This company not only has a group of high-quality, high-tech car maintenance technicians, but also purchases a number of conservative car maintenance testing equipment from international and foreign companies. For example: computer detection analyzer, fuel injection cleaning analyzer, four wheel aligner, atf active loop cleaning, etc. The factory is both soft and hard and perfect.
With a perfect maintenance service process, the process is as follows:
car maintenance
Car maintenance is very important. To buy a new car, you must first understand how to maintain it. Several tasks for car maintenance needs:
Clean the surface of the car and check that the door and window glass, wiper, indoor mirror, rear view mirror, door lock and lifter handle are fully effective. Check the amount of water in the radiator, the amount of oil in the crankcase, the fuel reserve in the tank, and the level of the electrolyte in the battery to meet the request. Check whether the horn and the light can be completely and effectively, and whether the installation can be strong. Check if the connection parts of the steering mechanism are loose and the installation is strong. Check if the tire pressure is sufficient and eliminate the debris between the tires and the tread. Check whether the running clearance of the steering wheel can meet the standard; whether the hub bearing and the knuckle king pin can be loosened. Check that the free path of the clutch and brake pedal is in compliance with the rules.
Check tire nuts, axle bolts, leaf spring riding bolts and u-bolts for robustness. After starting the engine, observe whether the instrument task is normal and listen to the engine for abnormal noise. Check the vehicle for “four leaks” such as water leakage, oil leakage, air leakage, and leakage. Check if the trailer installation task is reliable.
The role of the oil is to smooth, cool, seal, clean, rust, and prevent the engine. Without the oil, the heart of the car will not function properly. Use mineral oil and change the oil for 5,000 km. The correct oil change standard is calculated based on “engine operation time”. x = number of oil change kilometers.
Five steps to change the engine oil:
. Correctly select the quality level and viscosity grade of the smooth oil.
. Use high-quality oil filter cartridges consumed by the orbital manufacturers to prevent smoothing due to oil blockage, insufficient pressure or poor filtration performance caused by filter quality results.
. When changing the oil, turn off the engine when the engine is at normal mission temperature, unscrew the fuel filler cap, remove the oil drain screw and release the old oil, and use the utility tool to unscrew the old filter. The engine should be cleaned when conditions permit to completely clean the sludge and gel in the engine.
. When changing the new filter element, check whether the filter seal ring is intact. If it is found that there is deformation or damage, it should be changed in time. When removing the filter element, fill the filter element with clean and smooth oil and apply smooth oil to the seal to prevent protection during installation.
After the oil filter is installed, tighten the oil drain screw and add a certain amount of new smooth oil to the engine crankcase as required. The oil dipstick and oil level should be between the high and low score lines, install the dipstick and tighten the filler cap. Start the engine for a few minutes and check whether the oil pressure is normal and whether there is any oil leakage. If there is any abnormality, stop it and check it out. The oil should not be added too much or too little. Too much will cause the smooth oil consumption to be too fast, the engine running resistance will increase, and the fuel consumption will increase. Too little will result in low oil pressure and poor smoothness.
In addition to changing the oil, car maintenance should also check the electronic control components of the car with a computer tester. Check engine oil level, engine coolant level, active transmission smooth oil level, brake oil level, power steering smooth oil level and tire pressure. When it comes to tire pressure, many car owners see that the wheels are flat, thinking that the air pressure is not enough, and pumping the car tires until they are not flat. In fact, this is wrong. Too high tire pressure causes the tire to wear prematurely. When driving on the highway, it is very risky to have a flat blow. It is not good for the tire pressure to be too low. It is best to check the car manual or the instruction label on the side of the driver's door according to the standard of each car.
Check and change the brake fluid of the car: The brake fluid should be checked for a certain amount of time, and it needs to be changed if necessary. After a certain amount of time, the brake fluid will have a boiling point reduction, purification and varying degrees of oxidative enthalpy change. Therefore, the quality function should be checked in time according to climate, environmental conditions, seasonal changes and working conditions, so that it can be changed in time. Under normal working conditions, the brake fluid should be changed after 2 years or 50,000 kilometers. In principle, different types of brake fluid can not be mixed, so as to avoid chemical reaction between each other and affect the braking effect. The brake fluid used is often different for different models. Brake fluids include mineral oil type brake fluids and decomposable brake fluids. Decomposed brake fluids have many advantages that are commonly used.
In addition, when changing the brake fluid, professional replacement equipment should be used, so that the brake fluid can be changed more completely, no impurities remain, and the air resistance can be prevented, and the performance of the brake fluid can be effectively prevented from changing in the wild. Such as the brake is soft, the discharge valve is protected.
1. Change of engine spark plug
Although there is no strict change of oil requirements in terms of time and mileage. However, if you do not change the spark plug for a long time, it will affect the engine's mission and life. Spark plugs are generally divided into two types, one is a common type, and the spark plug has a service life of two years or four thousand kilometers. Another platinum spark plug, which has a lifetime of up to 120,000 km or five years due to the use of platinum. The spark plugs of most cars can be changed by themselves, especially the four-cylinder engine is simpler. There are only two sizes of spark plugs for household cars all over the world. If you want to change the spark plugs, you can go to the auto parts store such as autozone or autoparts, report the age and model of your car, buy the spark plugs that match your car, and then serve. The student can change the tool by changing the spark plug.
2, install the car
When the car body is seriously deformed, the mechanic must remove the engine, the instrument panel, the seat, the axle and other components. After the body is corrected, the master will install it. In my internship, just in our group, I installed a car. Above I briefly describe the steps of its disassembly:
Fixed engine
The v6 engine is fixed to the frame by four bolts via a damping block. In order to prevent the frame from being deformed due to a car accident, there are a plurality of bolt holes on the frame, so that the engine can be properly fixed to the frame.
Install engine components such as the transmission joystick: Once the engine is fixed, the transmission lever can be wired to the engine gearbox. The clutch can also be fixed on the conflicting piece push rod, and the exhaust pipe at the bottom of the frame is connected to the engine air pipe.
Install gantry, safety bar
Install engine and air conditioning cooling shutters and cooling oil pipe heat pipe assembly on the gantry. Fix the gantry to the back of the engine and install the safety bar.
Air conditioning blower and power steering pump
Half shaft
Fix the two ends of the left and right axles of the front wheel drive on both sides of the wheel and the transfer case.
Steering system
The direction controller assembly is mounted around the cabin and is connected to the steering rod through the universal joint. The steering wheel is initially adjusted to the position master assembly.
wiring
Today's more high-end cars, the more complicated the electronic control part, the more sensors, the line is very single. Pay special attention to the direction of the installation and the use of each harness during installation. Otherwise, the wire harness will be too short or too long. This asks the car mechanic to be very familiar with the route of the car. Pay special attention to the characteristics of the size, hole position and color of the two plug holes when connecting the connectors. Because of the difficulty in reducing the work of the car mechanic, the characteristics of the harnesses of different uses are different.
Installing the wiper assembly
When installing the wiper assembly, first remove the central control computer board, otherwise it will be difficult to install due to insufficient space. For the trouble-shooting car, adjust the two bolt holes of the fixed wiper on the frame, otherwise there will be abnormal noise when the wiper is installed.
Instrumentation and task station
The circuit of the instrument assembly is an ancient integrated circuit, and only the corresponding plug is required to be inserted thereon. Air conditioning air volume control port, negative driving status airbag and bracket for fixed task platform should be installed on the task platform.
Load the battery and start the engine test
When installing the battery, the total ground wire bolts should be sanded with sandpaper to make them electrically conductive. When installing the terminal, it is necessary to install the positive electrode and then install the negative electrode to prevent the accidental installation of the negative electrode and the iron to cause sparks.
Start the engine test, add engine oil, steering booster oil, brake fluid, coolant, air filter and gasoline before the test, and carefully check it to start. After starting, use a computer tester to check for other problems and then debug.

Part 5: Auto Repair Intern Summary

This year, my internship at the auto company is coming to an end. Through this internship, I have made great progress in my professional knowledge and other aspects. Through the internship, I have a deeper understanding of the car. Through work, I was able to step into the higher threshold of the automotive industry, embark on the road of automobile development, and strive to become a good car person. There may be many people working in the automotive industry, but not everyone has the opportunity to dismantle the car. The company has spent a lot of manpower, financial resources and material resources, providing us with a very rare opportunity to dismantle the car, providing us with rapid growth. Good condition, I think every new employee should be grateful for the company's contribution and proud and proud of being a member of the technology center. In the process of scrapping the car, I got the help of the supervisor, the instructor and many colleagues. Every time I don’t understand, they always answer meticulously and patiently. If you use your heart to find out, you can always learn a lot of knowledge. I can understand a lot of questions that I can't read. Of course, I would like to thank those supervisors, instructors and colleagues who are enthusiastic about helping me.
Through the car internship, I gained a lot of things, learned the basic structure and basic knowledge of the car, enhanced the spirit of teamwork, realized the importance of teamwork in the work, and enhanced the positive face and overcome difficulties and hardship. The ability to work hard has laid a good foundation for future adaptation to work.
For the dismantling of the whole vehicle, we follow a strict process, with a clear division of labor, each class is divided into three groups - the main split group, the split group and the data login group, which are all for us to successfully complete the car repair internship It has played a very important role.
Before the official car dismantling, we first measured the vehicle's vehicle attitude and took pictures of each posture of the vehicle. After that, there were some preparations before the car was dismantled, such as power outage, water discharge and oil drain. After that, we entered the formal dismantling process. Under the guidance of the on-site supervision, the dismantling of the whole vehicle was carried out in a tense and orderly manner. Firstly, the four doors and two covers were removed. Since most of the colleagues did not have the experience of dismantling the car, they did not find the skills during the dismantling and caused the dismantling to be slower. Then start to remove the bumper and fender. Before the car was dismantled, I always thought that the bumpers were made of materials that were compared with the strength of metal. However, when the car was dismantled, the bumper of the car we removed was plastic. It felt a little difficult to understand. The bumper was plastic. How do you play the role of insurance in the event of a car accident? The explanation of others has made me out of the misunderstanding that the bumper must be made of metal. The original use of plastic also has its advantages. The main function of the bumper on the passenger car is to absorb part of the energy during the collision, thus ensuring the safety of the vehicle occupants. There is no energy absorbing block behind the front bumper of the car, and the other two cars have energy absorbing blocks. This way the energy absorption effect may be better. In addition, the bumper can also play a decorative role, while also reducing the weight of the vehicle, I think it may also be related to pedestrian protection. Also, the name and function of the various lights of the car were not very clear. The explanation of the work of the electrical department was that I understood the names and functions of the various lights of the car. After that, I asked the supervisor of our class to guide me. The understanding of the headlight system has been deepened, and the high beam, low beam, position light, brake light, turn signal and reverse light have been clarified. There are still many things like this. I think if I am not involved in the dismantling of the vehicle, I am still a car blind, and I don’t even know the most basic car common sense. After that, we dismantled the chassis part of the vehicle including the clutch-transmission, front axle, rear axle, front overhang, rear overhang, and brake and steering related structures, and then removed the engine. In the disassembly of the vehicle, the engine and the transmission were not removed, but the engine and the transmission were disconnected at the clutch. I saw the structure of the clutch in the book before disconnecting the clutch, but I still didn't understand what happened after watching it for a while. After disassembling the clutch, I asked some of my more familiar colleagues about the problem, in their patience. Under the answer, I basically understand the working principle of the clutch. Sometimes, some things can't be understood by reading books. It is relatively easy to understand by observing things and other people's explanations. There are still many things to be learned at work in the future. In the process of learning, we must pay attention to methods and use correctness. The method can get twice the result with half the effort.
The process of dismantling fully reflects the importance of teamwork. In the process of dismantling, many people are doing different work, and each work must cooperate with each other, otherwise it is easy to make mistakes. For example, if the demolished person is doing too fast, the record may not be able to keep up, so it is easy to remember the mistake, and it will affect the subsequent data login work; each step must be taken before the disassembly, this will start The dismantling personnel and the photographers should be coordinated, and the photo recording work must be coordinated with the recording personnel.
Since we will change jobs after a while, each of us has an understanding of different jobs and has done every step of the car. In addition to the disassembly, the information of the parts and the data entry work is also very important, and relatively boring, but these two tasks need to be more careful. The measurement of standard parts is relatively simple, as long as some key information on nominal diameter, thread length, end thickness, end diameter and weight is measured. Some parts are more complicated, not only to measure the basic dimensions of length, width and height but also to analyze the vacancies. Some parts have holes of dozens to dozens, and some empty measurements are compared. Difficulties, this requires care and patience, in addition to record their additional information. The work of data logging is even more so. It is more prone to errors in the face of a large amount of data, pictures and forms. Therefore, every step of every work requires everyone's meticulous patience and needs everyone's efforts and cooperation.
In addition to the disassembly of the entire vehicle, I also participated in the dismantling of the Camry seat, and also dismantled the transmissions of Triumph and Elysee with our colleagues in the chassis division. I thought the seat was relatively simple, but by disassembling the seat by the staff of Dongfeng Lear, I realized that the seat of the car is not so simple. There are many considerations in the design process of the seat. Problems such as cost, manufacturing process, etc. Since I was engaged in transmission-related work in the future, I was more serious and careful when disassembling the two transmissions. I figured out a lot of problems that I did not understand before, analyzed their respective shifting mechanisms, and compared the two types. The advantages and disadvantages of the transmission. Although the two transmissions are all produced by a company, the general structure is similar, but there are still many differences in the details. For example, the track gears on both reverse shafts are directly driven by the reverse fork, but the triumphant transmission can ensure that the reverse gear rotates with the input shaft at any time. In turn, it is ensured that the three reverse gears are synchronized when the reverse gear is engaged, and the Elysee transmission does not have such a structure.
I learned a lot of things and also exposed some problems. At the beginning of the car, everything was quite novel, so it was still quite motivated. When the body was hit in the last few days, it was not too busy because it was not working properly. You should also reflect on the following. It is impossible for future work to be new content. How to maintain your work enthusiasm is very important. You must learn from those who have been working actively.
I would like to thank the company for providing such a good opportunity, and also to those who have been helpful in helping me, so that I have learned a lot through the dismantling and internship, and I have some relevant knowledge for future work. In addition, during the process of car dismantling, Also know the problems that should be paid attention to during the design process, such as minimizing the quality of the parts, designing the process to take into account, using appropriate processes and materials to reduce costs, and making the design as reasonable as possible for installation and maintenance. . Although the car internship is just the beginning of our work, there is more to learn in the future work, but the knowledge we have learned and the correct working methods can be brought to future work, as long as we Adhere to continuous learning and adhere to the correct working methods, no matter what problems you encounter in your work in the future will eventually be solved.
