Sleeve outer wall grinding device for automobile

Abstract

The invention belongs to the technical field of equipment for grinding or polishing, and discloses a sleeve outer wall grinding device for an automobile. The sleeve outer wall grinding device comprises a base, and the base is internally provided with a first cavity and a second cavity. The first cavity is internally provided with a first piston, and a first push rod is disposed on the first piston; and a second piston is disposed in the second cavity, and a second push rod is connected between the first piston and the second piston. A dust collection opening and an air exhaust opening are formed in the upper surface of the base. An air outlet pipe and an air inlet pipe are disposed on the lower portion of the first cavity. The base is provided with annular moving grooves, and limiting blocks are disposed on the inner wall of the moving grooves. Annular supporting plates are disposed at the positions, located above the limiting blocks, in the moving grooves. Grinding cylinders are disposed on the supporting plates, and grinding brushes are disposed on the inner walls of the grinding cylinders. A grinding head and an air cylinder for driving the grinding head to move are arranged above the base. The sleeve outer wall grinding device for the automobile solves the problems that in the prior art, no contact between the grinding ring and the sleeve is achieved, and therefore, the grinding effect is poor since debris generated by a grinding sleeve is difficult to discharge and accumulated between a grinding ring and the sleeve.

Description

technical field [0001] The invention belongs to the field of equipment for grinding or polishing, in particular to a grinding device for the outer wall of a sleeve used in automobiles. Background technique [0002] Automobile refers to a non-track-bearing vehicle driven by power and having 4 or more wheels. Because the car is easy to use, it is gradually popularized, and the socket for the car has also become one of the commonly used tools in people's life. The end face of the sleeve includes hexagon and dodecagon, the most commonly used of which is hexagon. [0003] When producing the sleeve, in order to avoid rust, its outer wall needs to be polished. The traditional external wall grinding is to manually hold the sleeve and then use sandpaper for grinding. This method is time-consuming and laborious, and it is not easy to produce in batches. Therefore, a kind of grinding device has appeared in order to solve the above-mentioned problem, comprises base, is provided with ...
