Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and specifically discloses an assembly welding tool for a rear cross beam of an automobile roof. Background Art

[0002] In order to improve the strength of the automobile roof assembly, it is usually achieved by providing a reinforcing crossbeam on the outer panel of the roof and increasing the material thickness of the outer panel of the roof and each reinforcing crossbeam. Therefore, the rear crossbeam of the automobile roof has become an important component in the automobile.

[0003] The existing welding process of the automobile roof and the rear cross beam is usually completed using a welding tool. In the process of assembly and welding, the automobile roof and the rear cross beam are usually clamped and positioned using a positioning fixture of the welding tool, so as to pre-install the automobile roof and the rear cross beam, and then the rear cross beam is welded to the rear end of the automobile roof to complete the assembly. However, due to the arc-shaped shape of the automobile roof, the existing welding tool is likely to cause the overall structure of the automobile roof to tilt when clamping and positioning the automobile roof, and the rear cross beam is likely to be installed tilted accordingly, which is not convenient for the welding operation of the rear cross beam on the automobile roof, affecting the welding quality and the automobile production quality. Therefore, in view of this, the inventor provides a welding tool for the rear cross beam of the automobile roof to solve the above-mentioned problem. Utility Model Content
