[0002] During the manufacturing process of an automotive storage plate, it is necessary to first stamp the plate into a target shape (usually a box shape), and then punch holes and weld components such as lugs on the plate. Currently, during the welding of the lugs, the lugs are usually placed at the welding position and then welded using welding equipment. However, without setting up a positioning fixture for the automotive storage plate and a positioning fixture for the lugs, during the welding process, the lugs and the automotive storage rack are very likely to move, resulting in a change in their relative positions, thereby causing welding failure.
