Outer circle honing tool

Abstract

An outer circle honing tool comprises a guide piston, a connecting joint connected with a vertical honing machine, a fixed joint and an outer circle honing head. One end of the fixed joint is connected with the outer circle honing head, the other end of the fixed joint is connected with the connecting joint, the outer circle honing head is composed of an oilstone, a spring and a honing head barrel, the oilstone used for grinding an outer circle to be machined is arranged in the honing head barrel, the spring is arranged between the honing head barrel and the oilstone, the guide piston is arranged in the honing head barrel and is in contact with one end of the oilstone, and the other end of the oilstone is in contact with the outer circle to be machined of a part to be machined. The problem that a high-precision and high-roughness outer circle at the non-rotation center is difficult to machine can be effectively solved, during outer circle honing, the precision can be 7 levels, the highest roughness can reach Ra is equal to 0.2 micrometer, and the product manufacturing quality can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of honing tools, in particular to an outer cylindrical honing tool. Background technique [0002] In general, high-precision and high-roughness outer circles are processed by using cylindrical grinders with high-speed rotating grinding wheels. The basic principle of most cylindrical grinders is that the grinding wheel is fed longitudinally relative to the workpiece, and the workpiece moves longitudinally. The characteristics of the workpiece are largely limited by the size and structural characteristics of the workpiece. For example, when grinding the precision outer circle feature on the workpiece, the center of rotation of the precision outer circle of the workpiece must be corrected to coincide with the spindle center of the cylindrical grinder. If the workpiece is based on If the radius of gyration of the precision outer circle exceeds the radius of gyration of the machine tool or has an obvious eccentri...

Problems solved by technology

[0002] In general, high-precision and high-roughness outer circles are processed by using cylindrical grinders with high-speed rotating grinding wheels. The basic principle of most cylindrical grinders is that the grinding wheel is fed longitudinally relative to the workpiece, and the workpiece moves longitudinally. The characteristics of the workpiece are largely limited by the size and structural characteristics of the workpiece. For example, when grinding the precision outer circle feature on the workpiece, the center of rotation of the precision outer circle of the workpiece must be corrected to coincide with the spindle center of the cylindrical grinder. If the workpiece is based on If the radius of gyration of the precision outer circle exceeds the radius of gyration of the machine tool or has an obvious eccentric structure, the precision outer circle cannot be ground. Generally, it can only be processed by back-boring the outer circle combined with fitter polishing, which can easily lead to out-of-poor product quality.
