High-precision unit for grinding

Abstract

The invention discloses a high-precision device for grinding, comprising a frame body, a grinding chamber is fixedly connected to the inner corner of the frame body, a horizontal displacement mechanism is arranged at the middle position of one side of the frame body, and the horizontal The displacement mechanism includes an electric push rod, a fixed frame, a track and a traveling car respectively; the over-grinding bin of the present invention is used as a protective bin body, so that the materials to be ground can be pushed into the grinding bin, and under the structural cooperation of the grinding mechanism , it can form three sets of grinding tools that can be adjusted by displacement at the same time, so that cylindrical materials with different diameters can be clamped and positioned according to the clamping device for expansion or contraction adjustment, and the material is subjected to a multi-faceted grinding process, during which two sets of cones can be used. The conical structures of the grinding wheel and a set of conical brush wheels are in contact with the surface of the material, which promotes the grinding surface of the outer circle of the material to be further improved and prevents the rapid wear of the single set of grinding tools.

Description

technical field [0001] The present invention relates to the technical field of grinding devices, in particular to a high-precision device for grinding. Background technique [0002] Grinding is the use of high-speed rotating grinding wheels and other abrasive tools to process the surface of the workpiece. Grinding is used to process the inner and outer cylindrical surfaces, conical surfaces and planes of various workpieces, as well as special and complex forming surfaces such as threads, gears and splines. , Due to the high hardness of the abrasive grains, the abrasive tool has self-sharpening, and grinding can be used to process various materials, including hardened steel, high-strength alloy steel, cemented carbide, glass, ceramics, marble and other high-hardness metals and non-metallic materials. [0003] When grinding the inner and outer cylindrical surfaces of the workpiece material, the adjustment displacement of a single set of grinding tools is generally used to con...

AI Technical Summary

Problems solved by technology

[0003] When grinding the inner and outer cylindrical surfaces of the workpiece material, the adjustment displacement of a single set of grinding tools is generally used to contact the surface of the material, so as to perform the finishing grinding operation. However, processing by a set of grinding tools alone, not only It is difficult to contact with the side and end surface of the material, and it will cause a large degree of wear on the surface of the grinding tool, resulting in more frequent tool replacement. If the grinding work is performed by multiple sets of tools, the position adjustment of the tool will be inconvenient. It is difficult to ensure that the grinding surfaces of multiple sets of tools are in contact with the material surface at the same time, which increases the limitations of the grinding work and reduces the grinding efficiency of the material. As the grinding process continues, the grinding position of the material needs to be adjusted frequently, but After every adjustment, the axis of the material is difficult to automatically correct the position of the grinding tool, which may cause the material on the cylindrical surface to not completely contact with multiple grinding tools. Grinding at this time will cause the grinding of the outer circle of the material Notches or potholes appear, reducing the accuracy of material grinding and reducing the pass rate of material finishing production
