Grinding wheel safe installation and fixing mechanism

Abstract

The invention relates to the technical field of grinding wheel equipment, and discloses a grinding wheel safe installation and fixing mechanism. The grinding wheel safe installation and fixing mechanism comprises a grinding wheel machine shell, wherein a bearing is fixedly installed in the grinding wheel machine shell, a power output shaft is fixedly installed in the bearing, a clamping seat is fixedly connected to the position, located on the left side of the bearing, of the side wall of the inner cavity of the grinding wheel machine shell, a connecting shaft is fixedly connected to one end of the power output shaft, a grinding wheel is movably installed on the outer surface of the connecting shaft in a sleeving mode, and a clamping groove is formed in the inner side surface of the grinding wheel. According to the grinding wheel safe installation and fixing mechanism, a pressing rod is arranged on a threaded shaft, through the matching of a first hinge rod, a second hinge rod, a clamping rod and a clamping seat, the power output shaft can be fixed in the process of tightening a nut to fix the grinding wheel, thus the situation that the power output shaft is prone to following rotating in the tightening process of the nut is prevented, and after the nut is tightened, the free state of the power output shaft can be ensured.

Description

technical field [0001] The invention relates to the technical field of grinding wheel equipment, in particular to a mechanism for safely installing and fixing grinding wheels. Background technique [0002] Grinding machine is a common equipment used to sharpen various knives and tools. It is also used for grinding, deburring and cleaning of ordinary small parts. It is mainly composed of base, grinding wheel, motor or other power source, bracket, Composed of a protective cover and a water feeder, it can be divided into a hand-held grinder, a vertical grinder, a suspension grinder, and a desktop grinder. [0003] When the grinder is in use, it is necessary to install the grinding wheel on the power output shaft of the machine, and then use the chuck and the nut to fix the grinding wheel. However, when the nut is screwed, the output shaft is easy to rotate synchronously with the nut, so it is necessary to use The tool fixes the output shaft, which makes it more troublesome to ...

AI Technical Summary

Problems solved by technology

[0003] When the grinder is in use, it is necessary to install the grinding wheel on the power output shaft of the machine, and then use the chuck and the nut to fix the grinding wheel. However, when the nut is screwed, the output shaft is easy to rotate synchronously with the nut, so it is necessary to use The tool fixes the output shaft, which makes it more troublesome to tighten the nut. In the process of driving the grinding wheel to rotate by the power output shaft, due to the high speed of the output shaft and the fact that the grinding wheel is easily affected by external friction when it is working, the grinding wheel may Sliding occurs, and the nut is loose due to the rotation at the same time, which is prone to safety hazards when used for a long time
