Abstract
The present invention discloses an in-place non-contact detection method for a shaft workpiece. The method includes: establishing a detection system, calibrating the detection system and establishing a detection coordinate system; analyzing a pose of a workpiece in the detection system to establish a coordinate system of a workpiece clamping device; controlling the workpiece clamping device of a shaft workpiece processing machine tool to rotate, continuously acquiring data by a linear laser measuring instrument, and calculating and analyzing the acquired data to obtain an ideal reference axis of the shaft workpiece; continuously acquiring data of a detection part, and calculating and analyzing the acquired data to obtain actual machining precision of runout of a shaft neck of a camshaft; and continuously acquiring data of the detection part, and calculating and analyzing the acquired data to obtain machining precision of coaxiality of the shaft workpiece.
