A compound fixture with multi-station welding function in welding line

Abstract

The invention relates to a composite clamp with a welding assembly line multi-station welding function. The composite clamp comprises a side wall module, a lower automobile body module, a roof and cross beam module, a front wall connecting plate module and a roof and front cross beam module, wherein the roof and cross beam module is connected with the side wall module; the front wall connecting plate module is connected with the side wall module; and the roof and front cross beam module comprises a left roof and front cross beam module and a right roof and front cross beam module. The composite clamp comprises the five modules respectively including the side wall module, the lower automobile body module, the roof and cross beam module, the front wall connecting plate module and the roof and front cross beam module; and by the five modules, respective welding and all working procedures of welding of bodies in white of three production lines which are used for welding the bodies in white and are required for production of automobiles at present are realized.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures for automobile production lines, in particular to a composite fixture with multi-station welding functions in a welding assembly line. Background technique [0002] According to the automobile development process, the welding line has the ability to weld the body a few months later than the first sequence, and these months are the critical period of project development. Loading verification, a number of tests on the assembled vehicles, and the national announcement and declaration of the required vehicle volume. How to weld the body-in-white before the welding assembly line is ready for delivery is a problem that every OEM must face. [0003] The current technical solution is to make a simple welding line that is simpler than the normal welding line. Generally, the simple welding line is composed of four stations: cabin delivery station, side wall station, lower body station, and assembl...
