[0002] The automobile aluminum alloy front subframe is an important part of the automobile chassis system, mainly playing the role of supporting the front axle and suspension system and connecting it with the "main frame". In the automobile manufacturing industry, the welding of the aluminum alloy front subframe is usually carried out by an automatic welding robot. These robots can perform welding according to preset programs and paths to ensure welding quality and production efficiency. At the same time, in order to cope with complex welding tasks, the welding device also needs to be flexible and adaptable.

[0003] However, when the traditional method uses a robot to weld the automobile aluminum alloy front subframe, the automobile aluminum alloy front subframe is fixedly installed on the processing table, and the position of the automobile aluminum alloy front subframe remains unchanged. The welding is carried out by moving and adjusting the robot, which is likely to cause the welding torch of the robot to deviate from the welded part, resulting in the weld deviating from the predetermined position and affecting the welding quality. Moreover, there is only one welding station. When one automobile aluminum alloy front subframe is being welded, the preparation work cannot be carried out on the un-welded automobile aluminum alloy front subframe, thus reducing the welding efficiency. In view of the above problems, the inventor proposes a welding device for an automobile aluminum alloy front subframe to solve the above problems. Content of the Utility Model
