Abstract

The invention provides an automobile cantilever support welding fixture. According to the automobile cantilever support welding fixture, a first fixing module is adopted for fixing a first cantileversupport; a second fixing module and a third fixing module are adopted for fixing a second cantilever support; and a fourth fixing module is adopted for fixing a third cantilever support. The inventionfurther provides a multi-station welding system equipped with the automobile cantilever support welding fixture and a welding method of the multi-station welding system. In the multi-station weldingsystem, such automobile cantilever support welding fixtures need to be separately placed on at least two welding stations. According to a particular program, a welding robot is controlled through a control system to sequentially weld the first cantilever support, the second cantilever support and the third cantilever support which correspond to the automobile cantilever support welding fixtures onall the welding stations. The automobile cantilever support welding fixture adopts the semi-automatic mode, so that the cantilever support limiting and fixing precision can be improved, and the welding quality stability can be guaranteed; and meanwhile, the welding robot is used for sequential welding on the multiple welding stations, so that the production efficiency can be greatly improved.

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 cantilever bracket, a multi-station welding system and a welding method. Background technique [0002] The car cantilever bracket is used to fix and support the front and rear cantilever in the car, and the front and rear cantilever has an important influence on the safety and reliability of the car. Therefore, the processing accuracy and processing quality requirements of the automobile cantilever bracket are relatively high, such as the relative position size and flatness of the fixing holes. At present, for such automotive cantilever brackets that require high machining accuracy and require multiple parts to be welded into one assembly, the cantilever bracket parts are generally fixed by hand, and then manually welded. [0003] The stability of this method is not high, and the accuracy of manual limit fixing ...
