[0031] Specifically, the working principle of this metal part processing positioning welding device is: when in use, the lower part is placed on the surface of the placement seat 2 along the side wall of the positioning block 307, and the upper part is placed in the inner cavity of the first positioning frame 320. The first screw rod 304 can be driven to rotate by the motor 306, thereby driving the first threaded block 305 to drive the first cross plate 303 and the transverse frame 301 to move, so that the welding head 302 moves toward the surface of the part, and the first driving block 316 is driven downward by the second driving block 318, thereby driving the first connecting rod 314 and the worm 315 to move downward synchronously, thereby driving the worm wheel 312 and the bidirectional screw rod 310 to rotate, and driving the second threaded blocks 311 on both sides to drive the clamping block 308 to move closer, so as to clamp and fix the parts on the surface of the placement seat 2 for easy use.

[0032] When the motor 306 drives the welding head 302 to move toward the surface of the part, the first driving block 316 is driven downward by the second driving block 318, and the lifting plate 401 is driven to descend synchronously by the third connecting rod 409, and the third driving block 407 is driven to move rightward under the action of the arc groove 412, thereby driving the second connecting rod 404 and the rubber block 403 to move rightward synchronously, so that the rubber block 403 is closely attached to the side wall of the part, so that the upper part is driven to be closely attached to the surface of the lower part during the descending process of the lifting plate 401, thereby improving the welding quality; When welding on one side of the part is completed, the motor 306 drives the welding head 302 to move away from the surface of the part, so that the second driving block 318 is separated from the surface of the first driving block 316, and under the action of the first spring 317, the first driving block 316 is driven to move upward, driving the push plate 420 to move upward synchronously, thereby pushing the extrusion ring 418 and the first piston 416 to move upward, injecting the air in the cavity 415 into the jet seat 413, and spraying it to the surface of the part through the spray hole 414, so as to dissipate heat at the welding point of the part and clean the welding slag at the same time.

[0033] After the welding head 302 completes welding on one side of the part, the electric telescopic rod 508 contracts and drives the tooth plate 506 to move backward, thereby driving the gear 507 and the placement seat 2 to rotate counterclockwise by ninety degrees to complete the face change of the part. At the same time, the second piston 509 is driven to move in the inner cavity of the pumping cylinder 505 through the fourth connecting rod 510, and the first one-way valve 512 is connected to pump the preservative in the liquid storage tank 511 into the pumping cylinder 505; after the welding is completed, the electric telescopic rod 508 drives the tooth plate 506 to move forward, drives the placement seat 2 to rotate clockwise by ninety degrees for reset, and at the same time, drives the second piston 509 to move to the inner cavity of the pumping cylinder 505 through the fourth connecting rod 510, and the second one-way valve 513 is connected to inject the preservative in the pumping cylinder 505 into the branch pipe 502 and the nozzle 503, and is sprayed onto the surface of the part by the atomizing nozzle 504, so as to spray the preservative on the welding part to prevent the parts from rusting.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
