The working principle of the invention is as follows:
the first linear driver 6a, the second linear driver 7a and the third linear driver 7b are all ball screw sliding tables or electric push rods or other precise drivers with stepping linear driving functions.
The run-out value detector 6b is an electronic lever dial indicator, an electronic ruler, a laser ranging sensor or other sensors with relative distance detection functions, and judges the circular run-out value of the shaft workpiece by detecting the change of the relative distance between the outer circumferential surface of the shaft workpiece and the induction end of the shaft workpiece.
The correcting piece 7c is made of copper or other metal with hardness smaller than that of the shaft workpiece, and is used for extruding the shaft workpiece to enable the shaft workpiece to generate plastic bending, but the extrusion surface cannot generate plastic deformation.
Firstly, a shaft workpiece is horizontally placed on a detection table 4, then a rotary driving mechanism 5 drives the shaft workpiece to rotate around the axis of the shaft workpiece, and a run-out value detector 6b detects the circular run-out value of the outer circumferential surface of the rotating shaft workpiece;
in the detection process, the first linear driver 6a drives the run-out value detector 6b to move along the direction parallel to the axis of the shaft-type workpiece, so that the run-out value detector 6b can detect the run-out values of different parts of the outer circumferential surface of the shaft-type workpiece, and the run-out value detector 6b sends all detection data to the controller;
after the detection is finished, the controller compares the circle run-out values of different parts of the outer circumferential surface of the shaft workpiece to obtain the part with the maximum circle run-out value of the outer circumferential surface of the shaft workpiece, and then the controller sends signals to the rotary driving mechanism 5 and the correcting mechanism 7;
the rotary driving mechanism 5 drives the shaft-type workpiece to rotate, so that the part with the largest circle run-out value on the outer circumferential surface of the shaft-type workpiece is farthest away from the sensing end of the run-out value detector 6b, namely the part moves towards the direction closest to the output end of the correcting mechanism 7;
the second linear driver 7a drives the third linear driver 7b to move along the direction parallel to the axis of the shaft-like workpiece, so as to drive the correcting piece 7c to move to the position with the largest circular runout value on the outer circumferential surface of the shaft-like workpiece, the third linear driver 7b drives the correcting piece 7c to be close to the shaft-like workpiece and extrude the shaft-like workpiece, and the extrusion distance is the circular runout value of the position;
after the correction is finished, the rotary driving mechanism 5 drives the shaft-type workpiece to rotate again, and meanwhile, the detection mechanism 6 detects the shaft-type workpiece again to detect whether the circle run-out value of each part is in a qualified range.
