[0002] In the welding process of heavy-duty truck battery boxes, their frames and bottom bracket frames, accurate and fast positioning is the key to ensuring welding quality and efficiency. Traditional positioning methods usually rely on threaded connection fixation, that is, the position is fixed by tightening the positioning columns with the threaded holes on the top of the operating table. Multiple positioning columns threadedly connected to the operating table use their side extrusion and limitation to limit the frame steel pipe, so that the welding robot arm performs welding operations on the connection of the frame steel pipe. After welding is completed, the positioning columns need to be disassembled. However, when facing large-scale frame welding, the installation and disassembly process of multiple threaded positioning columns is time-consuming, which affects the rapid welding of the battery box frame and the bottom bracket. Therefore, in order to solve these problems, the utility model proposes a welding mechanism for battery frames and battery bottom brackets. Utility Model Content
