Grinding wheel device

Abstract

The invention provides a grinding wheel grinding device, which belongs to the technical field of grinding. The utility model solves the problem that the grinding wheel wears a lot when the existing grinding wheel grinding device performs edge processing on the diamond cutting tool. The grinding wheel grinding device includes a frame, a lifting plate and a grinding wheel. The lifting plate and the frame are connected through the first guide assembly; the grinding wheel is installed on the lifting plate, and the first motor is installed on the lifting plate; Ejector, the upper end of the ejector is in contact with the lifting plate; a lifting drive assembly with a second motor is installed on the frame, the ejector is connected with the lifting drive assembly, and the lifting drive assembly can drive the ejector to move up or down to realize The lifting plate moves up or down. During the sharpening process of diamond cutting tools by using the grinding wheel grinding device, the moving plate will automatically move upward when grinding the corners or accidentally protruding parts, thereby reducing the force between the grinding wheel and the diamond head, so that the grinding wheel is not easy to wear .

Description

technical field [0001] The invention belongs to the technical field of grinding, and relates to a grinding device, in particular to a grinding wheel grinding device. Background technique [0002] Grinding wheel is the most important type of grinding tool in grinding; therefore, there are many types of grinding wheel grinding devices, such as general grinders; Special grinding devices such as diamond cutter head bottom surface grinding machine (application publication number CN108161610A). Grinding devices usually have a grinding wheel lifting mechanism that can move the grinding wheel up and down, so that the amount of grinding can be controlled and the wear of the grinding wheel can be compensated. [0003] The diamond segment plays a cutting role in the cutting tool, and the diamond segment has the characteristics of high hardness. After the cutting tool is welded, it is usually necessary to grind the diamond tip, commonly known as sharpening. There are many technical s...

Problems solved by technology

[0004] figure 1 It indicates that the grinding wheel grinds the diamond segment, and the dotted line indicates the theoretical trajectory of the grinding wheel surface. However, since the diamond segment is formed by sintering, the diamond segment has low precision, and the corners usually have burrs and high hardness. During the grinding process, the wear of the grinding wheel is relatively large, especially when grinding edges and corners. Therefore, the actual trajectory line of the grinding wheel surface deviates from the theoretical trajectory line, but basically coincides with the dotted line

Generally speaking, when the existing grinding wheel grinding device is used to sharpen the diamond cutting tool, there are problems of large amount of grinding wheel wear and a small number of cutting tools processed by a single grinding wheel.
