The function of the auto frame straightening machine is to repair the body of the accident car. After the car collides, it is used to straighten the deformed part of the collision depression and restore it to the factory value. It is a necessary equipment for the car repair shop. The quality of collision repair equipment directly affects the effect of vehicle maintenance, so it is very important for auto repair shops to choose a high-quality and low-cost equipment.

At present, there are two types of auto frame machine: bench type and platform type, also known as European type and American type. The main feature of the European-style bench is its strong functionality, and the straightening of various parts can be realized through the 180-degree bending of the straightening and the movement on the frame, without dead ends. The American-style platform is a corrective equipment that realizes the maintenance and disassembly of the chassis through the lifting function of the platform, and realizes the straightening function through the 360° ring-shaped working pulling tower controlled by the power pump.

When we choose auto frame straightening machine, we need to consider the following functions that is the most important:

1.Equipment safety performance

The materials, specifications, parameters, manufacturing process and design structure of each component of the equipment are extremely important. If these links are not strictly required, there will be safety hazards in terms of equipment quality, service life and stability of use. The auto frame straightening frame machine is similar to the positioning model when building a car. It is used to calibrate some key holes in the car body. Due to collisions, the dimensions of many holes in the car body will change. The auto frame machine is equipped with very accurate measuring tools. General measuring tools allow The error is ±1mm,

Therefore, the auto frame straightening machine can completely restore the deformed body to the level of a new car, improve the maintenance quality, and also improve the driving stability and safety of the vehicle. 

2 The performance of the equipment

Can the equipment meet the requirements of use? Can it provide the convenience of use? It is an important indicator to measure the function of the equipment.

(1) Workbench: Can it provide a safe platform? Can it meet the fixed tension of the tower column? For example: the platform structure equipment can meet the convenience of the vehicle driving up and down, which has a greater advantage than the bench type

(2) Pulling tower: Can the pulling tower move safely and flexibly? Can it reduce the labor intensity of maintenance personnel? Can the pulling post withstand a wider range of straightening?

The main function of an auto frame machine is straightening and pulling. In general, 4 general-purpose large-side clamps are used to fix the damaged body, and then the deformed part is straightened with a pulling arm. The pulling tower can rotate 360° along the track to realize the all-round straightening of the body. The pulling towers can be moved and fixed arbitrarily within the platform track, and each pulling tower can be adjusted to achieve multi-point, all-round simultaneous straightening and improve work efficiency. At the same time, it is equipped with upward and downward straighteners to make upward and downward straightening more convenient. The disassembly and straightening of the accident car can be completed on the same station, which not only saves time but also improves work efficiency.

(3) Main fixture. Can it be quickly adjusted in the height direction and keep the height consistent? Is it convenient to fix the jaws? Can the height be adjusted after the vehicle is fixed on the platform?

(4) Hydraulic straightening. The hydraulic straightening system should be powerful, stable and reliable in work, and capable of metering operations.

In summary, the auto frame machine has the following characteristics: it can perform high-strength vehicle body positioning and fixing; it is equipped with maintenance straightening tools of various shapes and functions, which can meet the needs of repairing different parts of the vehicle body; it can perform multi-point, all-round Correction straightening and repair work; it can realize accurate body data measurement, and accurately detect the deviation of each reference point and repair error.

Nowadays, the automotive sheet metal repair business is becoming more and more optimistic. Various automotive 4S shops and comprehensive repair shops have increased investment in sheet metal repair business, equipped with various advanced body repair equipment and highly skilled personnel, so that It occupies a place in the fierce market competition. The role of auto frame straightening machine in contemporary automobile sheet metal maintenance will become more and more important. Therefore, it is more important to have an in-depth understanding of auto frame machine in order to choose an equipment that suits you.
