Paper Abstract

Mechanical failure is primarily caused by coaxiality errors of axis. Traditional methods (synthetic gauge testing methods, method of rotary axis, coordinate measuring machine, etc.) for detecting coaxiality have some disadvantages such as: low efficiency, sensitive to human factors and cannot be used to measure the axis that is far apart without connection. In this paper, based on the principle of laser collimation, a method for measuring coaxiality errors of non-connecting axis with long distance was proposed. By rotating the laser module and the four-quadrant photo detector module respectively, the center and radius of the circle that formed by the laser spot were used to calculate the angular deviation and the parallel deviation. Finally, a measurement system based on the precision instrument deflection was designed to verify the rationality of the method.
