Circumferential symmetry type shaft workpiece run-out detection and correction machine

Abstract

The invention relates to the field of secondary machining of shaft workpieces, in particular to a circumferential symmetry type shaft workpiece run-out detection and correction machine. The circumferential symmetry type shaft workpiece run-out detection and correction machine comprises a detection table, a rotation driving mechanism, a detection mechanism and a correction mechanism, wherein the detection table is used for horizontally placing a shaft workpiece; the rotation driving mechanism is used for driving the shaft workpiece placed on the detection table to rotate around the axis of theshaft workpiece; the detection mechanism is used for detecting the concentricity of the outer circumferential surface of the shaft workpiece placed on the detection table; the correction mechanism isused for correcting the curvature of the shaft workpiece placed on the detection table; the detection mechanism comprises a first linear driver and a run-out value detector; and the correction mechanism comprises a second linear driver, a third linear driver and a correcting piece. The machine is used for detecting the circular run-out value of each part of the outer circumferential surface of theshaft workpiece so as to judge the curvature of the shaft workpiece, and correcting the curvature according to the detection result, so that a qualified shaft workpiece with higher straightness is obtained. Compared with the prior art, the machine has the advantages of automation and high efficiency.

Description

technical field [0001] The invention relates to the field of secondary processing of shaft workpieces, in particular to a circumferentially symmetrical shaft workpiece runout detection and correction machine. Background technique [0002] At present, shaft workpieces often have the problem of insufficient straightness after processing. By erecting the two ends of the shaft workpiece and then squeezing the middle, the straightness of the shaft workpiece can be eliminated to a certain extent. Defects. [0003] However, the current equipment is all to squeeze the middle of the shaft workpiece, but the bending position of the shaft workpiece is not necessarily in the middle, so the effect of eliminating straightness defects is not ideal. [0004] Therefore, there is a need for a device that can automatically detect the bending position of the shaft workpiece, and squeeze the bending position to eliminate its straightness defects. Contents of the invention [0005] In order t...
