A grinding wheel safety installation and fixing mechanism

Abstract

The invention relates to the technical field of grinding wheel equipment, and discloses a grinding wheel safety installation and fixing mechanism, which includes a grinding machine shell, and a bearing is fixedly installed inside the grinding wheel shell, and a power output shaft is fixedly installed inside the bearing. The side wall of the inner cavity of the grinder shell is located on the left side of the bearing and is fixedly connected with a card seat. One end of the power output shaft is fixedly connected with a connecting shaft. The outer surface of the connecting shaft is movably fitted with a grinding wheel. The inner surface of the grinding wheel There are card slots. The grinding wheel is safely installed and fixed. By setting the pressing rod at the threaded shaft and the cooperation of the first hinged rod, the second hinged rod, the clamping rod and the clamping seat, the nut is tightened to fix the grinding wheel. It can ensure that the power output shaft is fixed, thereby preventing the power output shaft from easily following rotation during the screwing process of the nut, and can ensure the free state of the power output shaft after the nut is tightened.

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
