Abrasive and grinding machine capable of accurately adjusting grinding degree

Abstract

The invention relates to the technical field of abrasive and grinding machine equipment, in particular to an abrasive and grinding machine capable of accurately adjusting the grinding degree. The abrasive and grinding machine comprises a bottom plate; one side of the upper surface of the bottom plate is fixedly connected with a vertically-upward supporting plate, and a clamping mechanism is arranged on the surface, facing the other side of the bottom plate, of the supporting plate; the upper surface of the bottom plate is connected with a movable plate through a transmission mechanism, and theside, away from the supporting plate, of the upper surface of the movable plate is connected with a rotating motor through screws; an output shaft of the rotating motor is connected with one end of arotary shaft through a coupling, and an abrasive disc is fixedly mounted at the other end of the rotary shaft in a sleeving mode; and the middle of the rotary shaft is fixedly mounted in a bearing ina sleeved mode, and the bearing is fixedly connected to the corresponding position of the upper surface of the movable plate through a support. The middle of the rotary shaft is rotationally supported through the bearing, thus the accuracy of long-time rotation of the rotary shaft can be ensured, the radial offset of the rotary shaft is reduced, the phenomenon of offset of the rotary shaft is avoided to the greatest extent, and thus the degree of accuracy of the abrasive disc during grinding can be ensured.

Description

technical field [0001] The invention relates to the technical field of abrasive abrasive equipment, in particular to an abrasive abrasive which can precisely adjust the grinding degree. Background technique [0002] Abrasives are a general term for abrasives and abrasives, including abrasive products and abrasive products. Abrasives are known as industrial teeth. Abrasives or abrasives are often used as grinding tools to mechanically process parts to be processed during grinding. Processing, and to meet certain technical requirements, commonly used abrasive grinding has cutting discs and grinding wheel discs, louver discs, quick-change grinding discs, grinding rolls, bonded grinding wheels, Chiba grinding rings and sandpaper grinding rings. [0003] Since the motor shaft drives the rotating shaft to rotate for a long time, the radial offset of the rotating shaft may gradually increase with the increase of the use time, which will affect the rotation accuracy of the rotating ...

AI Technical Summary

Problems solved by technology

[0003] Since the motor shaft drives the rotating shaft to rotate for a long time, the radial offset of the rotating shaft may gradually increase with the increase of the use time, which will affect the rotation accuracy of the rotating shaft, resulting in a decrease in the accuracy of the abrasive tool;

[0004] In the process of use, insufficient clamping force will cause displacement of the workpiece during processing, resulting in reduced machining accuracy. However, if the inclination angle of the clamping block needs to be changed frequently, the filler block needs to be replaced many times at this time, resulting in overall failure. Convenience is greatly reduced. Therefore, an abrasive abrasive tool that can precisely adjust the grinding degree is proposed.
