[0031] During operation, place the door frame 410 on the base 210 so that the positioning block 220 abuts against the side wall of the door frame 410 to achieve the positioning and fixing of the door frame 410; subsequently, place the connecting seat 420 on the door frame 410, and then positionally fix the connecting seat 420 to the door frame 410 through the plug pin 230; finally, drive the welding head 320 to move through the multi-axis manipulator 310 to weld and fix the connecting seat 420 and the door frame 410. By using the above-mentioned positioning tooling 200 to position and fix the door frame 410 and the connecting seat 420, the structure is simple, the operation is convenient, the work efficiency is improved, and the welding quality is improved; by using the multi-axis manipulator 310 to drive the welding head 320 to move to achieve welding, welding at different positions and angles can be realized, the overall occupied area is reduced, and the structure is reasonable and compact.

Under normal circumstances, the distance between the positioning blocks 220 on both sides of the base 210 is less than the length of both sides of the corresponding door frame 410. When it is necessary to place the door frame 410 on the base 210, the positioning block 220 slides along the mounting hole 211 to adjust the position of the positioning block 220, so as to facilitate the placement of the door frame 410.
