[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model, but not to limit the utility model.

[0037] Reference Figure 1 The utility model provides a grinding device for automobile bolt processing, comprising a base 1 and a cover body 2.

[0038] The cover 2 is mounted above the base 1. A conveying assembly 11 is disposed on the top of the base 1. The conveying assembly 11 includes a conveyor belt 11a and fixing members 11b equidistantly disposed on the conveyor belt 11a. Figure 4 The fixing part 11b is provided with a groove 11b1 corresponding to the head of the bolt. If the bolt is an internal angle bolt, a protrusion corresponding to the internal angle can be provided in the groove 11b1, so that the head of the bolt can be movably embedded and fixed in the groove 11b1. The conveyor belt 11a drives the fixing part 11b to pass through the cover 2. The cover 2 is provided with a lifting and lowering grinding assembly 21, which includes a driving motor 21a and a grinding ring 21b coaxially arranged with the driving motor 21a. The grinding ring 21b can be provided with multiple equal distances according to the spacing of the fixing part 11b. Figure 3The inner ring and the inner top of the grinding ring 21b are made of abrasive material, and the abrasive material can be corundum, silicon carbide, etc. Specifically, a grinding layer is formed on the inner ring and the inner top of the metal grinding ring 21b. Figure 2 The side wall of the grinding ring 21b is provided with a plurality of chip discharge holes 21b1, which are preferably provided on the side wall near the top of the grinding ring 21b. The grinding assembly 21 is connected to the cover body 2 via a telescopic motor 22, and the grinding ring 21b is started to descend so that the screw part of the bolt enters the inner ring of the grinding ring 21b for grinding.
