Valve seat positioning system and positioning method in laser cladding processing, and laser cladding processing system and processing method

摘要

PPROBLEM TO BE SOLVED: To provide a positioning system and method for a valve seat in the laser clad machining for attaining high machining accuracy by specifying the position of a valve hole with excellent accuracy when the valve seat (a cylinder head) is rotated, and a laser clad machining system and method. PSOLUTION: The positioning system 10 comprises a sensor 1 for measuring the position of the valve seat V when the cylinder head C rotated at least once, and a position calculation device 4 for specifying the position of the valve seat when the cylinder head is rotated by correcting the measured data on the position of the valve seat V during the rotation on the basis of the correction coefficient with at least weight of the cylinder head and the deflection at the position of the valve seat added thereto. The actual laser clad machining is achieved in a posture with the coordinate center calculated by the position calculation device 4 as a center of rotation. PCOPYRIGHT: (C)2008,JPO&INPIT
