Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8One embodiment of the present invention is as follows: a welding device for processing automotive parts includes a base 1, a welding cover 2 fixedly connected to the top of the base 1, a discharge plate 10 fixedly connected to the top of the base 1, a welding mechanism 7 and a cleaning mechanism 8 provided on the top of the base 1, a collection mechanism 9 provided at the bottom of the base 1, a connecting column 5 rotatably connected to the top of the welding cover 2, a motor 4 provided on the connecting column 5, a protective arc plate 3 slidably connected to the circumferential surface of the welding cover 2, and a crash shield 6 fixedly connected to the top of the base 1. The welding mechanism 7 includes a rotating column 701, a rotating long plate 702, a rotating circular plate 703, a sliding block 704, a protective door 705, a movable cylinder 706, a telescopic rod 707, a fixing strip 708, and a welding head 709. The components include a fixed disc 710, a slot 711, a telescopic spring rod 712, a rotating column 701 whose top is fixedly connected to the bottom of a connecting column 5, a rotating long plate 702 fixedly connected to the circumferential surface, a rotating circular plate 703 fixedly connected to the bottom of the rotating column 701, a slot 711 formed on the inner surface of the welding cover 2, a sliding block 704 slidably connected to the inner wall of the slot 711, a protective door 705 fixedly connected to the bottom of the sliding block 704, a movable cylinder 706 slidably connected to the bottom groove of the rotating circular plate 703, a telescopic rod 707 fixedly connected to the bottom of the movable cylinder 706, a fixing strip 708 fixedly connected to the circumferential surface of the telescopic rod 707, a welding head 709 fixedly connected to the bottom of the telescopic rod 707, and a telescopic spring rod 712 fixedly connected to the fixing strip. At the bottom of 708, the fixed disc 710 is fixedly connected to the bottom of the telescopic spring rod 712. When the device is started, the output end of the motor 4 drives the connecting column 5 to rotate, the connecting column 5 drives the rotating column 701 to rotate, the rotating column 701 drives the rotating disc 703 to rotate, the rotating disc 703 drives the moving column 706 to rotate, the moving column 706 drives the telescopic rod 707 to rotate, the telescopic rod 707 drives the fixed bar 708 to rotate, the fixed bar 708 drives the telescopic spring rod 712 to rotate, the telescopic spring rod 712 drives the fixed disc 710 to rotate, the telescopic rod 707 drives the welding head 709 to rotate, and the welding head 709 rotates.

The 9mm welding angle allows for pressing and limiting of the workpiece, preventing it from shifting during welding, thus improving the welding accuracy of the device, ensuring welding quality, and reducing welding deviations. Simultaneously, the rotating column 701 rotates, driving the rotating long plate 702 to rotate as well. During rotation, the rotating long plate 702 contacts and pushes the sliding block 704, which in turn drives the protective door 705 to rotate and overlap with the protective arc plate 3. This prevents sparks generated during welding from contacting other objects. The welding cover 2 further protects the safety of welding with this device, reducing the frequency of accidents during welding.

Simultaneously, the outer cylinder 906 is sleeved on the surface of the inner rod 904, and adhesive tape is attached to the surface of the outer cylinder 906. When the inner rod 904 moves the outer cylinder 906, the adhesive layer on the surface of the outer cylinder 906 will attract fine dust particles. When moved, the adhesive layer on the surface of the outer cylinder 906 will attract fine dust. At the same time, the surface of the inner rod 904 has a long arc plate 907 and a spring 908, which makes the outer cylinder 906 stably connected to the inner rod 904. A certain curvature is provided on one side of the long arc plate 907. The surface of the outer cylinder 906 is covered with adhesive tape.

At the same time, the absorbent cotton block 809 also comes into contact with the parts and absorbs water stains on the surface of the parts, further improving the post-weld effect and increasing the efficiency and quality of welding.

[0028] Simultaneously, during the movement of the push block 802, the push block 802 will drive the spinning column 811 on the rotating column 805 to rotate. The spinning column 811 will drive and squeeze the rotating rod 902 to rotate around the connecting block 903.
