Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically to welding fixtures for the left and right halves of a vehicle frame main beam. Background Technology

[0002] The chassis is a frame structure that spans the front and rear axles of a car, commonly known as the main beam. It is the base of the car and is generally composed of two longitudinal beams and several transverse beams. It is supported on the wheels via the suspension system, front axle, and rear axle. The chassis must have sufficient strength and rigidity to withstand the load of the car and the impact transmitted from the wheels. The function of the chassis is to support and connect the various assemblies of the car, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the car.

[0003] When welding the left and right halves of the main beam of the vehicle frame, manual clamping and welding are usually performed. This makes it difficult to clamp and position the main beam, and it is impossible to adjust the position of the main beam according to the welding situation. The operation is relatively simple, which affects the welding efficiency, increases the labor intensity of workers, and makes it difficult to guarantee the welding quality. Utility Model Content

[0004] The purpose of this utility model is to provide welding fixtures for the left and right halves of the main beam of a vehicle frame, so as to solve the problems mentioned in the background art.
