Technical Field

The invention belongs to the technical field of machining, and particularly relates to a planer tool for a tool withdrawal groove of a grinding wheel.

Background

A planing tool is a tool for planing operations having a cutting portion. The plane blade may be classified into a longitudinal cutting, a transverse cutting, a grooving, a cutting, a forming plane blade, and the like according to the use. The planer tool is basically similar to a turning tool in structure, but the planer tool is used for intermittent cutting and is subjected to impact load. Therefore, under the same cutting section, the section size of the cutter bar is 1.25-1.5 times larger than that of a turning tool, and a larger negative edge inclination angle (-10 degrees to-20 degrees) is adopted, so that the impact load resistance of the cutting edge is improved. In order to prevent the tool shank of the planing tool from bending and deforming under the cutting force, so that the blade bites into the workpiece, an elbow planing tool is generally used. Heavy machinery is often manufactured by welding and mechanically clamping a planer tool, i.e. a blade is welded on a small tool bit and then clamped on a tool bar, so as to facilitate the welding, sharpening, assembling and disassembling of the tool. When planing large planes, a rolling planer tool can be adopted, and the cutting part of the planing tool is a bowl-shaped tool bit. The circular cutting edge continuously rotates under the action of cutting force, so that the tool is uniformly worn and has long service life.

When machining both side surfaces of the guide rail, a grinding wheel is usually required to perform grinding machining to ensure the accuracy of the guide rail. However, when the grinding wheel is used for grinding, the lower ends of the two sides of the guide rail are required to be processed to obtain the grinding wheel tool withdrawal grooves with the lower ends arranged obliquely inwards so as to avoid the grinding wheel, and therefore, the grinding precision is better guaranteed. However, when the conventional plane cutter is used for machining a tool withdrawal groove of a grinding wheel, a five-axis numerical control machine tool is required to be used for machining, so that the equipment cost is increased. In addition, the existing plane cutter is inconvenient to replace the partial structure of the cutter head and the cutter blade, so that the cutter is high in cost; secondly still inconvenient use, tool setting waste time influences machining efficiency.

Therefore, what is needed is a grinding wheel escape planer tool which has a simple structure, can be used more conveniently, can process a grinding wheel escape groove more conveniently, and can reduce the cost, and the problem to be solved by those skilled in the art is solved.
