Third, the internship time

20xx-2-27 to 20xx-4-20

Fourth, the internship content:

This company not only has a group of high-quality and skilled automobile maintenance technicians, but also buys a group of advanced automobile maintenance testing equipment from home and abroad. For example: computer detection analyzer, fuel injection cleaning analyzer, four-wheel locator, etc. , making the software and hardware of the factory perfect. There is a perfect maintenance service process, which is as follows:

1, automobile maintenance

Clean the appearance of the car, and check whether the door and window glass, wiper, indoor mirror, rearview mirror, door lock and lifter handle are complete and effective. Check whether the water quantity of the radiator, the oil quantity of the crankcase, the oil storage quantity of the oil tank and the electrolyte level in the battery meet the requirements. Check whether the horn and lighting are complete and effective, and whether the installation is firm. Check whether the connecting parts of the steering mechanism are loose and firmly installed. Check whether the tire pressure is sufficient and remove impurities between the tire and the wheel track. Check whether the running clearance of the steering wheel meets the standard; Whether the hub bearing and steering knuckle kingpin are loose. Check whether the free travel of clutch and brake pedal meets the requirements. Check whether the tire nut and axle bolt are firm and reliable. After starting the engine, check whether the instrument works normally and listen to the engine for abnormal sounds. Check whether the vehicle has "four leaks" such as water leakage, oil leakage, air leakage and electric leakage. Check whether the traction and installation work is reliable.

The main functions of engine oil are lubrication, cooling, sealing, cleaning, rust prevention and engine corrosion prevention. Without engine oil, the heart of a car can't work normally. Use mineral oil, and generally change the oil every 5000 kilometers. The correct oil change standard is calculated by "engine running time". (Self-estimated average speed: km/h) x (100h/mineral oil-200h/synthetic oil) = oil change kilometers.

Inspection and replacement of automobile brake fluid: After the automobile has been running for a certain period of time, check the brake fluid and replace it if necessary. After being used for a certain period of time, the brake fluid will have different degrees of boiling point reduction, pollution, oxidation deterioration and other phenomena. The quality and performance of brake fluid should be checked in time according to the climate, environmental conditions, seasonal changes and working conditions, so as to replace it in time. Under normal working conditions, the brake fluid should be replaced after 2 years or 50,000 kilometers. In principle, different types of brake fluid should not be mixed, so as to avoid chemical reaction between them and affect the braking effect. Different models often use different brake fluids. Brake fluid includes mineral oil brake fluid and synthetic brake fluid. Synthetic brake fluid has many advantages and is widely used.

In addition, professional replacement equipment should be used when replacing brake fluid, so that the brake fluid can be replaced more thoroughly, without impurity residue, avoiding air resistance and effectively avoiding the common problems of manual replacement of brake fluid. For example, the brake is soft and the air release valve is damaged.

2. Although replacing the engine spark plug is not as strict as replacing the oil in time and mileage. However, if the spark plug is not replaced for a long time, it will also affect the work and life of the engine. Spark plugs are generally divided into two types, one is the ordinary type, and the service life of this spark plug is two years or 48 thousand kilometers. Another platinum spark plug, made of platinum material, has a service life of120,000 km or five years. Spark plugs in most cars can be replaced by themselves, especially in four-cylinder engines. There are only two sizes of spark plugs for family cars all over the world. If you want to replace the spark plug yourself, you can go to Toyota to open an auto parts store, report the age and model of your car, buy a spark plug that matches your car, and then borrow the tool for replacing the spark plug from the waiter to replace it yourself.

3. Common fault diagnosis and selection methods of automobile wiper.

Scraping more than 654.38+00,000 times. According to the international driving safety survey, when driving in rainy days, the traffic accident rate caused by the aging wiper is about 5 times higher than usual!

It's not, seeing that the weather is warm, the rainy season is coming. If there is anything wrong with your wiper, you must find a way to repair it quickly. We specially used Sunday's rest time to visit the masters of several auto repair shops, and the answer was: prescribe the right medicine and give different diagnosis methods according to the different symptoms of wiper. Wiper hardening: replacing wiper or rubber sheet: I wonder if you have noticed? It feels good to use the wiper when it rains heavily, but when it rains lightly, you will find that the wiper will leave uneven wiping marks on the glass surface; Sometimes it gets stuck on the glass, causing poor eyesight. This situation indicates that the wiper has hardened. If this fault is eliminated, we must first understand the working principle of the wiper. It turns out that the wiper is transformed into one-to-one motion through the rotation of the motor and the connecting rod, and this force is transmitted to the wiper arm and the wiper itself. When the rubber part of the wiper hardens, the wiper can't closely adhere to the glass surface, or when the wiper has scars, it will cause uneven wiping and form residual dirt.

The replacement of wiper or wiper rubber is very simple, but it should be noted that the installation method and length of wiper are different for different models and years. Some wipers only need to replace the rubber plate.

1. If the wiper arm is vertical, it will stand up; If it is not vertical, it will be shielded. Wet the glass surface first, and turn off the motor switch when the wiper is in an easy-to-replace position.

2. The installation methods of wiper are U hook type and screw locking type. Hook-type users only need to pull up the hook to pull down the wiper.

3. It is best to compare the length of the removed wiper with that of the newly installed wiper to see if they are the same, and then observe whether the installation method is the same.

4. Insert the wiper as far as possible in the original way to fix it.

5, wet the windshield, observe whether the wiper action is normal.

Wiper arm failure, replace the wiper arm: the wiper is in close contact with the windshield through the force of the wiper arm spring. When the tension of the spring becomes weak, the wiper will float or hang on the windshield due to the strong wind pressure brought to the windshield when driving at high speed. In order to completely eliminate this fault, it is best to update the rain wiper arm as a whole.

1. Remove the sleeve of the wiper arm mount.

2. Loosen the retaining nut and remove it.

3. Put the wiper arm in an upright position, and then it will fall off with a slight movement.

4. Replace the wiper body on the new wiper arm.

5. Tighten the nut at the wiper stop, and finally install the cover.

Five, internship gains and feelings

During the internship, I also found some problems, that is, there is great waste and pollution in the process of automobile maintenance. When repairing a car, many parts are intact and don't need to be replaced at all, but just because a small part connected with them is damaged, they are all replaced and eventually become a pile of scrap iron. After all, it is not easy for those parts to start from iron until they are processed and shaped. It takes a lot of resources and energy to turn them into scrap iron directly without any damage, which is really a waste; There is also a lot of residual oil flowing out when repairing the car, and the oil in the garage is washed away directly with water, which is a waste of resources and serious pollution. I think these aspects need to be paid attention to and gradually improved when repairing cars. In the machinery industry, we should advocate the recycling of spare parts, and those second-hand spare parts with good performance should be reused instead of being scrapped directly. This is very important for the country to build a resource-saving society.

Sixth, the internship summary

I learned a lot of knowledge I wanted to learn in this company, which gave us a deeper understanding of the automobile industry. I know I learned very little at school, and there are still many things we don't know. During the internship, I learned the knowledge about automobiles from the masters seriously, started working actively, cultivated the spirit of hard work, carefully understood the body structure, strengthened the maintenance skills, and laid a good foundation for future work.
