After grinding is completed, the part is taken away by the clamping rod 820, and under the action of the fourth spring 908, the insertion rod 902 is driven to move up for reset, and at the same time, the piston 907 moves up, and the air in the air cavity 906 is pressed into the hollow part of the insertion rod 902 and into the cavity 911, and finally sprayed from the spray hole 912 to the surface of the placement seat 7, so as to clean the grinding debris on the surface of the placement seat 7 and facilitate the placement of the next part.

[0032] In a preferred embodiment, when in use, after the parts are grabbed onto the surface of the placement seat 7, the load-bearing plate 901 is pressed down under the action of the gravity of the parts, so that the load-bearing plate 901 drives the insertion rod 902 to move downward, and the fourth connecting rod 905 drives the positioning blocks 903 on both sides to move closer, so that the positioning blocks 903 are clamped on the side walls of the parts and positioned with the parts to facilitate subsequent grinding. After the grinding is completed, the parts are removed by the clamping rod 820, and under the action of the fourth spring 908, the insertion rod 902 is driven to move up for reset, and at the same time, the piston 907 moves up, and the air in the air cavity 906 is pressed into the hollow part of the insertion rod 902 and into the cavity 911, and finally sprayed from the spray hole 912 to the surface of the placement seat 7, so as to clean the grinding debris on the surface of the placement seat 7 and facilitate the placement of the next part.

[0033] Specifically, the working principle of this type of automotive parts spot welding and grinding equipment is as follows: when in use, the grinding seat 511 is moved to the top of the placement seat 7 by the first motor 505 and the second motor 509, and the welding spot is captured by the visual camera 525, and then the driving roller 512 is driven to rotate by the third motor 524, thereby driving the grinding belt 515 to rotate, and the grinding seat 511 is driven to move downward by the first electric telescopic rod 510, so that the positioning ring 519 contacts the surface of the component, and as the grinding seat 511 continues to move downward, the positioning ring 519 moves upward relatively, driving the first tooth plate 521 to move upward synchronously, thereby driving the second tooth plate 522 and the grinding roller 514 to move downward, and the raised welding spot is ground, and the lowest point to which the grinding belt 515 can descend is the bottom plane of the positioning ring 519, so it will not cause excessive grinding, thereby ensuring the welding quality of the parts.

[0034] When the first motor 505 drives the slide plate 502 to move toward the surface of the feed rack 3, the mounting frame 506 can impact the impact rod 807, thereby driving the third tooth plate 806 to move backward, driving the second gear 805 to rotate, driving the turntable 802 to rotate, and cleaning the welding slag and splashes on the surface of the automobile parts through the brush 803, so as to achieve pre-grinding of the parts and improve the grinding quality. At the same time, when the third tooth plate 806 drives the second gear 805 to rotate counterclockwise, it drives the fourth tooth plates 814 on both sides to move closer, so that the parts on the surface of the conveyor belt are positioned through the clamping plate 811 to ensure the stability of cleaning, and then the slide seat 817 is driven downward by the second electric telescopic rod 816 to move the clamping rod 820 to the side wall of the part, and then the third electric telescopic rod 821 is contracted, and the clamping rods 820 on both sides are moved closer to clamp and fix the parts, so that the parts can be grabbed to the surface of the placement seat 7 to complete the loading.

[0035] After the parts are grabbed onto the surface of the placement seat 7, the load-bearing plate 901 is pressed down under the action of the gravity of the parts, so that the load-bearing plate 901 drives the insertion rod 902 to move downward, and drives the positioning blocks 903 on both sides to move closer through the fourth connecting rod 905, so that the positioning blocks 903 are clamped on the side walls of the parts and positioned with the parts to facilitate subsequent grinding. After the grinding is completed, the parts are taken away through the clamping rod 820, and under the action of the fourth spring 908, the insertion rod 902 is driven to move up for reset, and at the same time, the piston 907 moves up, and the air in the air cavity 906 is pressed into the hollow part of the insertion rod 902 and enters the cavity 911, and finally sprayed from the nozzle 912 to the surface of the placement seat 7, so as to clean the grinding debris on the surface of the placement seat 7 and facilitate the placement of the next part.

[0036] 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.
