Finally, welding can be performed. This can ensure the relative position relationship of the various parts during welding.

[0003] The existing automated welding jig has a poor fixing effect, which can easily cause one end of the weld to warp, resulting in incomplete limiting effect of the jig, thereby reducing the accuracy of the finished weld size and affecting subsequent use. For this reason, we propose a pneumatic jig to assist automated welding. Utility Model Content
