System for automatically detecting and diagnosing flexural deformation of axial line of workpiece

Abstract

The invention provides a system for automatically detecting and diagnosing flexural deformation of axial line of workpiece. When the workpiece is driven by a rotation control module to rotate around a rotation axial line, the system records the radial pulsation value of the workpiece and the rotation angle value of the workpirce, screens out the data generated by the form error of the sections, such as ellipse, triangle, bulge, burr and the like after the filtration treatment of an error diagnostician system, and extracts the measurement data generated by the flexure error of the axial line of the workpiece, thereby generating the standard space model of the flexure of the axial line, so as to complete the task of automatically detecting and diagnosing flexural deformation of axial line of the workpiece.

Description

technical field [0001] The invention relates to an error detection and diagnosis system in the field of detection technology, in particular to an automatic detection and diagnosis system for bending deformation of a workpiece axis. Background technique [0002] In the processing process of the shaft workpiece after heat treatment, the bending deformation of the workpiece axis during the heat treatment process should be corrected through the straightening process. Before straightening, the bending error of the axis should be measured first, and the maximum bending deformation point of the axis, as well as the starting point and end point of the maximum deformation should be determined according to the measurement results; then the straightening force should be applied at the maximum bending deformation point, and the starting point Alignment support points are arranged at the end point and the end point to promote the reverse deformation of the deformed part, thereby compensa...
