Title:
IN-PLACE NON-CONTACT DETECTION METHOD FOR SHAFT WORKPIECE
Document Type and Number:
WIPO Patent Application WO/2022/041986
Kind Code:
A1
Abstract:
Disclosed is an in-place non-contact detection method for a shaft workpiece, comprising the following steps: establishing a detection system, calibrating the detection system and establishing a detection coordinate system; analyzing a pose of the workpiece in the detection system to establish a coordinate system of a workpiece clamping device; controlling the clamping device of a shaft workpiece machining tool to rotate, performing continuous data acquisition by a linear laser measuring instrument, and calculating and analyzing the acquired data to obtain an ideal reference axis of the shaft workpiece; performing continuous data acquisition on a detection part by a laser displacement sensor, and calculating and analyzing the acquired data to obtain an actual runout machining precision of a camshaft journal; and performing continuous data acquisition on the detection part by the linear laser measuring instrument, and calculating and analyzing the acquired data to obtain a coaxiality machining precision of the shaft workpiece. The present invention can detect the journal center and ideal reference axis of a shaft workpiece in real time, and avoids system errors and compensation difficulties caused by using an ejector pin reference or a V-shaped block in a traditional method.
