Description

Technical Field

[0001] The utility model relates to the technical field of automobile lower swing arm welding, in particular to a welding positioning device for an automobile suspension lower swing arm. Background Art

[0002] The lower arm of the automobile chassis usually has three swing arms, also known as triangular arms, which are connected to the tire through the shaft head and play a certain supporting role. The end of the swing arm needs to be welded with an upper round tube to install components such as bushings or ball heads. In the prior art, the rear lower swing arm welding assembly is connected to the subframe as a bushing connection, and the bushing is pressed into the corresponding position of the end of the swing arm. The swing arm phase is adjusted by adjusting the adjustment device on one side of the subframe to change the wheel alignment parameters. Since the models of the lower swing arms of different models of vehicles are different, the existing lower swing arm welding and fixing devices have poor adaptability. Utility Model Content
