A shaft grinding process method and device for small pores

Abstract

The invention discloses a technological method and a device for grinding a shaft small hole, which aims at effectively protecting a cutter, greatly prolonging the service life of the cutter, improving the adjusting efficiency, and improving the product quality and production efficiency. The device adopts the technical scheme that the device comprises a sectioning clamp, wherein the sectioning clamp is of a two-step type sleeve tube structure, the interior of the sectioning clamp is fixedly provided with a grinding sample, the grinding sample has the same structure and size with a to-be-processed shaft type part, the contour of the grinding sample is of a three-step type structure, a large end of the grinding sample is provided with a hole along the axial direction, the cutter can extend into the hole, the interior of the hole is provided with a to-be-ground small fine hole, the head of the cutter can extend into the small fine hole in the grinding sample during processing, the inner wall structure of the sectioning clamp is matched with the shape of the grinding sample, the side wall of the grinding sample is provided with a notch along the axial direction, the side wall of the sectioning clamp is provided with an observation window corresponding to the notch of the grinding sample, and the internal structure of the grinding sample and the grinding position of the cutter can be conveniently observed through the notch and the observation window.

Description

technical field [0001] The invention relates to the field of machining, in particular to a process method and device for grinding small pores of shafts. Background technique [0002] Some 12-speed and 16-speed series one-axis structures have a small hole in the inner hole at the large end of the shaft head. The basic size is between Φ10mm-Φ16mm, and the tolerance is +0.018 / 0. Because the heat treatment deforms and the tolerance is very small, it is necessary to add a hole grinding process after the heat treatment. [0003] The quality of the products processed by traditional grinding is not stable, there will be taper holes, the roughness is poor, and it is easy to collide with the knife, damage the tool holder, grinding wheel, and bruise the workpiece. As a result, grinding small pores after heating has become a difficult point in processing, and this process has become a processing bottleneck. Contents of the invention [0004] In order to solve the problems in the pri...
