Then, adjust the length of the second sliding rod 19 and the second sleeve 18 to adjust the height of the lifting lugs until they contact the top outer wall of the cabinet 16. Finally, tighten the first fastening bolt to fix the second sliding rod 19. Then, adjust the support rod 23... The length of the sliding sleeve 21 is extended until the clamping block 28 contacts one side of the cabinet 16. At this time, the magnet attracts the cabinet 16 for limiting and fixing. Then, the clamping block 22 is clamped in the slot behind the support rod 23 to limit and block the support rod 23. Then, the third slider 24 is pulled to move, thereby driving the clamped lifting lug to move, and then moving the lifting lug to the welding position of the lifting lug on the cabinet 16. After that, the second fastening bolt is tightened to fix the third slider 24, thereby completing the positioning of the lifting lug.
[0028] Before welding, first, the first screw rod 7 is screwed to move the first sliding block 9 along the first sliding rod 8, so as to move the welding torch 13 horizontally, and then the welding position is adjusted horizontally; then, the screw rod is screwed to move the mounting rod 10 along the guide rod, so as to move the welding torch 13 vertically, and then the welding position is adjusted vertically, so that the welding torch 13 is aligned with the welding position of the lug; then, the second screw rod 12 is screwed to move the second sliding block 11 downward, so as to move the welding torch 13 downward to contact the welding position of the lug, and then the lug is welded by the welding torch 13.
