[0052] Specifically, the working principle of this automobile parts welding equipment is as follows: when in use, the parts to be welded are placed in the inner cavity of the material frame 3, and the second electric telescopic rod 5 drives the second push plate 4 to push the parts forward, and the nuts are placed in the loading barrel 601. Under the action of gravity, the nuts fall into the through groove 607, and under the action of the first spring 609, the first push plate 608 is driven to push the nut to the surface of the upper material tray 602, and the first motor 605 can drive the gear 604 to rotate, thereby driving the gear ring 603 to drive the loading tray 602 to rotate. When the placement cavity 606 rotates to the bottom of the nut, the nut falls into the placement cavity 606, and the first push plate 608 is driven to move backward by the protrusion 612 until the protrusion 612 is separated from the block 611, and the first spring 609 is reset again to push the next nut to the surface of the upper material tray 602, and this cycle is repeated. Subsequently, the screw rod 624 is driven to rotate by the second motor 626, thereby driving the threaded block 625 to drive the slide 619 to move, and the placement frame 620 is moved to the surface of the discharge barrel 617. The nut can be pushed into the two sets of clamps 621 through the first push ring 616, and under the action of the second spring 623, the clamps 621 on both sides are driven to move closer to clamp and fix the nut, completing the loading, which is convenient for use.

[0053] After the nut is pushed into the clamping block 621, the placement frame 620 is driven to move to the surface of the welding seat 704 by the second motor 626, and the welding seat 704 is driven to move upward by the fourth electric telescopic rod 706, and the limiting frames 707 on both sides are driven to move away from each other by the first wedge block 710 to break away from the limit on the parts, and then the positioning rod 705 is inserted into the inner cavity of the part, and the part is lifted up by the welding seat 704, and the second push ring 713 is pushed upward synchronously by the positioning rod 705, driving the push block 711 to move upward, pushing the second wedge blocks 715 and the support rod 622 on both sides to move away from each other, driving the clamping block 621 to move synchronously, thereby releasing the nut in the inner cavity of the clamping block 621 to the surface of the part, and then driving the slide 619 to move, so that the placement frame 620 is separated from the surface of the welding seat 704, and the welding head 703 can be driven downward by the third electric telescopic rod 702 to press on the surface of the nut, and the nut is welded to the surface of the part, thereby improving the welding efficiency.

[0054] After welding is completed, the second motor 626 drives the slide 619 to continue to move toward the discharge barrel 617, and the third connecting rod 801 drives the scraper block 802 to move synchronously, so that the welded parts are scraped into the lower hopper 803 by the scraper block 802, and then fall into the material box 804 for collection, which is convenient for use.

When the placement cavity 606 rotates to the bottom of the nut, the nut falls into the placement cavity 606, and then the slide 619 is driven to move by the second motor 626 to move the placement frame 620 to the surface of the discharge barrel 617, and the nut can be pushed into the two sets of clamping blocks 621 through the first push ring 616 to complete the loading;
