Many car owners attach great importance to car maintenance, but have they ever paid attention to car body correction? What is the key function of body maintenance? Let me take you to understand the operation process of body correction!

The operation flow of volume correction is 1 1. Before use, ensure that the air source is in place and all linkage operating mechanisms ensure flexible, safe, firm and reliable lubrication.

2. Add grease/hydraulic oil to the moving parts of the calibrator regularly, and clean and check the accessories (once a week). Do not use the accessories for other purposes.

3. Before use, ensure that there are no obstacles in the 2m range before and after the calibrator and in the left and right 1m range.

4. Before calibration, press the back of the calibrator to make it incline to the ground, and fasten the two connecting plates on the flat plate of the calibrator.

5. Before calibration, remove the four body support clips on the flat plate, then drive the vehicle to the flat plate along the platform slope, pull up the parking brake and place the anti-skid pad. Confirm that the vehicle is parked safely, and press the back of the straightening bench to raise it.

6. Fix the four supporting points of the chassis firmly first, and then find the correction stress point.

7. When the gripper is in the calibration operation state, the operator shall not stand on the front of the gripper. At this time, non-working personnel shall not get close to the operation area and keep a safe working distance.

8. After calibration, loosen the four support points of the chassis, put the vehicle on the platform and confirm that the parking brake is pulled up.

9. After applying pressure, tilt the straightening bench to the ground, and the vehicle will slowly slide down the platform.

Influence of Girder Correction on Car Body

Body rectification refers to the process of repairing the parts damaged by accidents or fatigue to the technical standard "state" through a certain external force when the vehicle leaves the factory.

The word "country" has two meanings. "Form" refers to a more intuitive appearance and shape, while "State" is a more abstract and profound concept.

For example, whether the internal molecular structure of metal can be rearranged according to the original position and whether the internal stress is completely released will directly affect the function and life of the vehicle after repair.

Structural parts refer to the parts that play the main supporting and bearing role on the car body, and are the installation basis of car body parts, which are commonly found in longitudinal beams, cross beams, doorposts and lower cross beams.

This kind of member usually has high strength, and the structure is mostly closed box section, so some measures should be taken and reasonable technology should be adopted to repair it.

Even if the correction is good, it is impossible to correct it to the level of a new car. On the other hand, if the correction is not good, it will lead to the acceleration jitter of the car. The faster the jitter, the more serious the vehicle deviation. It is recommended to drive carefully after maintenance. Or buy a new one.

Body Correction 2 1 Operation Process, Prerequisite for Body Correction

When the car body has a serious collision, it is necessary to correct the tension between the car body and the girder. After determining the damage degree of the overall body structure and fully understanding the damaged area.

If the stretching correction is needed according to the specific situation, it is necessary to remove the decorative parts and mechanical parts related to the collision before the "operating table" on the damaged vehicle, and then carry out stretching correction on the accident vehicle.

2. Characteristics of stretching equipment

① High-strength body positioning and fixing device.

(2) There are more maintenance tools with different shapes and functions, which can meet the maintenance needs of different parts and can carry out multi-point and all-round calibration and drawing work.

③ It can accurately detect the deviation and repair error of each datum point.

3. How to draw?

① Place the vehicle on the orthopedic frame.

② Fix the body position and close all calipers.

③ Drawing.

④ measurement. Measurement is an indispensable link in body repair, not only in
