Problems solved by technology

Moreover, most of these car fenders have complex structures and special welding positions. Currently, for automobile fenders with complex structures that require multiple parts to be welded into one assembly, the fender parts are generally fixed by hand, and then manually welded.
[0003] This kind of method is not stable, and the accuracy of manual limit fixing cannot be guaranteed, so the quality of the produced automobile fender components is different; and the manual limit fixing and welding are used, the production efficiency is low, mass production is not possible, and the degree of automation is not high. high

Abstract

The invention provides an automobile guard plate welding fixture, provides a multi-station welding system provided with the automobile guard plate welding fixture and further provides a welding methodof the multi-station welding system. According to the automobile guard plate welding fixture, a first guard plate is limited and fixed by a first fixing module and a second fixing module, and a second guard plate is limited and fixed by a third fixing module. According to the multi-station welding system, the automobile guard plate welding fixtures are independently placed on at least two weldingstations, and a welding robot is controlled to weld the first guard plate and the second guard plate on each automobile guard plate welding fixture sequentially. According to the welding method, a control system controls the welding robot to weld the first guard plates and second guard plates corresponding to the automobile guard plate welding fixtures on the welding stations in sequence according to a particular program. With the adoption of a semi-automatic mode, limiting and fixing precision of the guard plates is improved, welding quality stability is guaranteed, meanwhile, the multiple welding stations are sequentially welded by the welding robot, and therefore, the production efficiency is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of welding machinery and equipment, and in particular relates to a welding jig for an automobile guard plate, a multi-station welding system and a welding method. Background technique [0002] Car fenders are used to fix and protect some important parts in the car, such as oil pipes and so on. Therefore, the processing accuracy and processing quality requirements of the automobile guard plate are relatively high, such as the relative position size and flatness of the fixed hole positions, etc. Moreover, most of these automobile fenders have complex structures and special welding positions. Currently, for automobile fenders with complex structures that require multiple parts to be welded into one assembly, the fender parts are generally fixed by hand, and then manually welded. [0003] This kind of method is not stable, and the accuracy of manual limit fixing cannot be guaranteed, so the quality of the produ...
