When the motor 503 is working, the driving screw 504 can drive the welding slider 502 to move, thereby realizing the automatic welding of the workpiece; the setting of the two clamping and extruding frames 603 plays an automatic clamping role for the workpiece to be welded, thus saving the clamping time of the workpiece to be welded and improving the welding efficiency of the workpiece; when the two clamping and extruding frames 603 are separated from the two rectangular movable rods 302, the two V-shaped clamping plates 303 are in the two reset springs A Under the action of 305, it automatically moves outward, which is convenient for the workpiece to slide after welding, and also convenient for the staff to pre-install the workpiece to be welded; when welding the workpiece on the left, the staff can pre-install the workpiece to be welded on the right station, and when welding the workpiece on the right, the staff can pre-install the workpiece to be welded on the left station, which saves the installation time of the workpiece to be welded and improves the welding efficiency of the workpiece; the setting of the two supporting limit rods 604 has a limiting effect on the connection unloading plate 203, ensuring that the connection unloading plate 203 is in a stable state when the workpiece is welded, avoiding the movement of the workpiece during welding, and ensuring the welding accuracy of the workpiece;

[0063] After the welding process, the staff starts the electric cylinder 401 to shrink the output shaft of the electric cylinder 401; at this time, the output shaft of the electric cylinder 401 drives the temporary storage box 404 to move, so that the temporary storage box 404 moves out of the protective frame 403; when the output shaft of the electric cylinder 401 shrinks, the unloading plate 402 is pushed to squeeze the U-shaped unloading rack 204, and the U-shaped unloading rack 204 can be flipped downward after being squeezed, so that the connected unloading plate 203 is tilted, and the welded workpiece can automatically slide into the temporary storage box 404; when the welded workpiece is unloaded, the staff extends the output shaft of the electric cylinder 401, and the output shaft of the electric cylinder 401 drives the temporary storage box 404 to move, so that the temporary storage box 404 moves into the protective frame 403, avoiding the staff from installing the workpiece to be welded. When the workpiece is being scalded by the welded workpiece; when the staff extends the output shaft of the electric cylinder 401, the connecting unloading plate 203 can automatically reset under the action of the two reset bending springs 207; when the workpiece in the temporary storage box body 404 needs to be circulated, the staff pulls outward the two handles on the temporary storage box body 404; at this time, the output shaft of the electric cylinder 401 can squeeze the two circular connecting rods 406 to move outward, so that the two circular connecting rods 406 are separated from the arc groove 4011, which is convenient for the turnover of the welded workpiece; when the temporary storage box body 404 needs to be reset, the staff first slides the temporary storage box body 404 to the inside of the protective frame 403, and then pushes the two handles on the temporary storage box body 404 to insert the two circular connecting rods 406 into the arc groove 4011.
