Grinding wheel for high-speed railway

Abstract

The invention relates to a grinding wheel for a high-speed railway. The grinding wheel comprises a grinding wheel basic body and a grinding wheel main body. The grinding wheel main body is fixed to the position above the grinding wheel basic body, the grinding wheel basic body comprises a base, the base is sequentially provided with a first baffle, a second baffle, a third baffle and a fourth baffle from inside to outside in the circumferential direction, a circle of convex strips are arranged on the outer side of the first baffle in the circumferential direction, the outer side of the second baffle and the inner side of the second baffle are respectively provided with a circle of convex strips in the circumferential direction, the outer side of the third baffle and the inner side of the third baffle are respectively provided with a circle of convex strips in the circumferential direction, and the inner side of the fourth baffle is provided with a circle of convex strips in the circumferential direction. Thus, the grinding wheel basic body and the grinding wheel main body can be firmly fixed to form a whole and are not prone to falling off, the service life is prolonged, and use safety is guaranteed.

Description

technical field [0001] The invention relates to the connection technology of the grinding machine main shaft and the grinding wheel, more specifically, relates to a grinding wheel for high-speed railway. Background technique [0002] During the use of the grinding machine, in order to facilitate the connection between the grinding machine spindle and the resin bonded grinding wheel, to ensure interchangeability and installation connection accuracy, a metal plate is usually added between the above two. It is the base of the grinding wheel, and the base of the grinding wheel provides multiple screw holes with uniform distribution and accurate positions, which can not only be accurately installed and fastened on the main shaft of the grinding machine, but also have a certain effect on improving the strength of the grinding wheel. However, when rough grinding on a vertical grinding machine, the contact surface between the end surface of the grinding wheel and the workpiece is la...

AI Technical Summary

Problems solved by technology

However, when rough grinding on a vertical grinding machine, the contact surface between the end surface of the grinding wheel and the workpiece is large, and the grinding load is also relatively large. Especially when grinding the online rail of the railway, the grinding conditions are very bad. In the case of uneven conditions and rail joints, the impact force is very large. Although the flange on the main shaft of the grinding machine is closely connected with the base plate of the grinding wheel, when the grinding wheel is used on a high-speed railway, there may be damage between the grinding wheel and the base of the grinding wheel. Separation of the two due to tangential impact force
