[0123] Working principle: When welding operations are required on automobile parts, the staff will place the automobile parts to be welded in four clamps 407 in turn and fix them with four screws 408. Then the staff will turn on the cylinder 305 through the controller 6. The cylinder 305 extends to the right and drives the support ring 306 to move to the right. The support ring 306 moves to the right and drives the welding head 307 to move to the right until the welding head 307 moves to just above the annular baffle 503. At this time, the staff will turn off the cylinder 305 through the controller 6 and turn on the first motor 303. The rotation of the first motor 303 drives the first screw 302 to rotate. The rotation of the first screw 302 drives the slider 304 to move downward. The downward movement of the slider 304 drives the cylinder 305 to move downward. The downward movement of the cylinder 305 drives the second screw 409, the third screw 505 to move downward, and the support ring 306 to move downward in turn. When the cylinder 305 drives the support ring 306 to move downward, the support ring 306 moves downward to drive the welding head 307 to move downward, and the welding head 307 moves downward and passes through the annular baffle 503 until the welding head 307 contacts the parts to be welded. At this time, the staff turns off the first motor 303 through the controller 6 and turns on the welding head 307 at the same time, so as to perform the welding operation. When the welding is completed, the staff turns on the first motor 303 through the controller 6, and the first motor 303 rotates to drive the slider 304 to move upward, and the slider 304 moves upward to drive the cylinder 305 to move upward, and the cylinder 305 moves upward to sequentially drive the second screw 409, the third screw 505, and the support ring 306 to move upward. When the cylinder 305 drives the support ring 306 to move upward, the support ring 306 moves upward to drive the welding head 307 to move upward, and the welding head 307 moves upward to avoid damage to the welding head 307 due to collision when switching between workstations.

[0124] When the cylinder 305 moves upward and drives the second screw 409 to move upward, the second screw 409 moves upward and drives the first one-way bearing 410 to rotate, the first one-way bearing 410 rotates and drives the gear 411 to rotate, the gear 411 rotates and drives the annular gear plate to rotate, the annular gear plate rotates and drives the chassis 402 to rotate, the chassis 402 rotates and drives the workbench 403 to rotate, and the workbench 403 rotates and drives the four fixed plates 404 and the four connecting plates 405 to rotate in turn. When the workbench 403 rotates and drives the four connecting plates 405 to rotate, the four connecting plates 405 rotate and drive the four second motors 406 to rotate respectively, the four second motors 406 rotate and drive the four clamping plates 407 to rotate respectively, and the four clamping plates 407 rotate and drive the four parts to rotate respectively, so as to perform the station switching operation, so that the equipment can switch between different stations quickly and accurately, reducing the time required for changing workpieces or adjusting equipment, so that the equipment can continuously perform welding operations, significantly improving production efficiency.

[0125] When the cylinder 305 moves upward and drives the third screw 505 to move upward, the third screw 505 moves upward and drives the second one-way bearing 506 to rotate. The rotation of the second one-way bearing 506 drives the air purification fan 507 to rotate. The air purification fan 507 rotates, so that the exhaust gas in the welding box 2 passes through the arc plate 502, the air inlet pipe 512, the ventilation box 504, the ventilation pipe 509, and the water tank 510 in sequence, and is finally discharged from the exhaust pipe 511 after being filtered by the water tank 510, thereby achieving the effect of purifying the exhaust gas generated by welding, which helps to improve the working environment of the workshop and reduce the health problems of employees caused by long-term inhalation of harmful smoke.
