Although the device has the function of flipping the equipment components, it is impossible to perform spot welding processing on components of different shapes through the upper and lower welding heads. In addition, the device cannot play a stable clamping role for some special-shaped parts and pipes through the clamping plate, which easily causes position deviation problems during the spot welding process.

[0053] Working process: First, the worker starts the device and selects the state of the limit assembly 40 according to the equipment to be spot welded. When spot welding the plate, the lock assembly 70 releases the limit between the rotating frame 402 and the limit frame 401. At this time, one side of the rotating frame 402 is in contact with one side of the arc groove 403, and the two plates are stacked between the two limit frames 401. The second servo electric cylinder 501 driving end in the auxiliary positioning assembly 50 pushes the two limit frames 401 closer, and the plates are clamped and limited by the opposite sides of the two rotating frames 402. The spot welding assembly 20 is used to spot weld the stacked plates, and the Z-axis drive assembly 30 is used to drive the spot welding electrode head 206 to move forward, and then the electric push rod 20 The driving end pushes the movable block 205 to connect the spot welding electrode head 206 to move downward, and the upper and lower spot welding electrode heads 206 perform spot welding processing on the plate, and then the gear 54 is driven to rotate by the driving motor 51, and the chain 55 is used to drive another gear 54 to rotate, and the gear 54 drives the screw rod 52 to rotate, and the screw rod 52 drives the spot welding electrode head 206 to slide above the plate through the structure of the connecting block 53 and the slide plate 102, and the spot welding position is adjusted. The driving end of the first servo electric cylinder 301 in the Z-axis driving assembly 30 pushes the driving plate 302 to drive the spot welding electrode head 206 to move in the Z-axis direction, thereby increasing the spot welding range of the spot welding electrode head 206 on the plate, thereby expanding the practicality of the spot welding device;

[0054] When spot welding the pipe fitting, the locking block 701 is limited inside the through groove 704, the rotating frame 402 and the limiting frame 401 are in a horizontal state, and one side of the rotating frame 402 is in contact with the upper end of the limiting frame 401. At this time, the limiting assembly 40 clamps and limits the pipe fitting through the arc grooves 403 on one side of the two limiting frames 401 to ensure the stability of the pipe fitting during the spot welding process, and cooperates with the spot welding electrode head 206 to perform spot welding on the pipe fitting;

[0055] When spot welding the special-shaped part, the rotating frame 402 and the arc groove 403 are selected according to the appearance state of the special-shaped part to clamp the special-shaped part, and then the sliding frame 502 is pushed to move to one side of the limit frame 401 by the driving end of the second servo electric cylinder 501, and one end of the push rod 503 pushes the limit frame 401 to move, and at the same time, the positioning rod 504 at one end of the push rod 503 extends out from the movable hole 506 inside the arc groove 403, and the end of the positioning rod 504 is used to contact the surface of the special-shaped part. After a plurality of positioning rods 504 contact different positions on the surface of the special-shaped part, according to the distance between the special-shaped part and the limit frame 401, the other end of the positioning rod 504 compresses the spring 505, and the special-shaped part is positioned between the two limit frames 401 by a plurality of positioning rods 504, so as to realize the limit clamping of the special-shaped part, and the special-shaped part is spot welded in cooperation with the spot welding electrode head 206;

[0056] When spot welding is performed on the inclined surface of the special-shaped part, the mounting frame 203 is controlled to rotate on the front of the fixing frame 201 through the output end of the energy-saving motor, and the angle of the spot welding electrode head 206 set on the front of the mounting frame 203 is adjusted. At the same time, the position of the upper and lower spot welding components 20 is adjusted by using the connection structure of the screw rod 52 and the connecting block 53, so that the two spot welding electrode heads 206 are respectively located on the upper and lower sides of the inclined surface of the special-shaped part (such as Figure 4 As shown), the spot welding processing of the inclined surface of the special-shaped part is completed using the spot welding electrode heads 206 on the upper and lower sides.
