[0002] The vehicle frame, as the skeleton of the car, is the basic component that supports the overall structure of the car. It is usually composed of longitudinal beams and cross beams, which are connected by riveting or welding to form a solid overall structure. The main function of this structure is to support and install the engine, transmission system, body and various other components of the car, and ensure that these components can be correctly positioned relative to each other. The design and material selection of the frame are very important because they directly affect the strength, rigidity and durability of the car. The frame needs to be able to withstand the load of the car under various working conditions, including vibration and impact during driving, as well as possible collisions.

[0003] The vehicle frame can be divided into the front mounting bracket and the rear mounting bracket according to the front and rear positions. The front mounting bracket includes the headlights and fenders, and the headlights and front bumpers. The front bumpers and fenders are the key matching areas of the A-side of the vehicle, and are also the parts that customers pay more attention to. Usually, the positioning reference of the headlights is designed on the fenders, and the partial positioning reference of the front bumpers is also on the fenders. The final position of the fenders affects the position of the headlights and front bumpers, and ultimately affects the matching relationship between the headlights and fenders, front bumpers, and front bumpers. Therefore, the position of the fenders on the body is very critical. It is usually necessary to assemble the fenders in welding tooling to ensure the assembly accuracy of the fenders.

The integral external tooling can easily ensure the opening size of the fenders on both sides, but the tooling is large, the development cost is high, it is inconvenient to use, and the efficiency is low. Alternatively, the fender bracket is first screwed with the integral tooling, and then the fender is assembled with the integral external tooling, which requires an additional screwed sheet metal bracket. The tooling is also large, the development cost is high, and the assembly efficiency is low. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a fender front installation tool to solve the problem that in the existing front installation bracket, the fender assembly requires a large number of supporting tools, is inconvenient to use and has low operating efficiency.
