Grinding mechanism for preventing scraps from scratching grinding surface of object

Abstract

The invention relates to the technical field of grinding equipment, and discloses a grinding mechanism for preventing scraps from scratching the grinding surface of an object. The grinding mechanism comprises a body, the right side of the body is fixedly provided with a rotating shaft, and the right side of an inner cavity of the body is fixedly provided with a bidirectional screw rod. In the moving process of a piston plate, the exhaust side of the piston plate extrudes gas in the body, the gas is extruded, then an opening and closing plate is pushed to move upwards, small air holes are opened, then the gas is exhausted from the small air holes, and the gas continuously enters the inner cavity of the body from the external environment and is exhausted from the small air holes; convection heat dissipation of a grinding cylinder is achieved, the situation that due to the fact that the temperature of the grinding cylinder is too high, the loss speed of the grinding cylinder is increased is avoided, meanwhile, the pressure of the gas is increased after the gas is extruded, then the speed of the gas is increased after the gas is exhausted from the small air holes, and therefore scraps can be blown farther by the gas; and the scraps are further prevented from being located in the working area of the grinding cylinder to affect the grinding effect.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a grinding mechanism for preventing waste chips from scratching the grinding surface of an object. Background technique [0002] Grinding is a kind of surface modification technology. It is generally a processing method that uses rough objects to rub the surface of the material to change the physical properties of the material surface. [0003] Some existing grinding equipment contacts the surface of the object through a high-speed rotating grinding cylinder, and reciprocates on the surface of the object in the direction of the circumferential rotation of the grinding cylinder, thereby realizing the grinding function. However, in the above operations, the high-speed rotating grinding cylinder After touching the object, there will be waste debris, which will fall to the working area of ​​the grinding cylinder on the surface of the object with the circumferential rotatio...
