During the welding process, the four sides of the workpiece frame and the bent corners need to be welded, so the workpiece frame needs to be overturned by using a welding tool during the welding process. In the above case, manual welding is limited by the space of the workpiece shell, and the welding efficiency is low and the welding difficulty is great. At the same time, the existing tool is difficult to overturn the workpiece frame, and the workpiece frame is easy to be damaged during overturning.
