Coaxial Adjusting Method for Irregular Rotating Workpiece
At present,most coaxial adjustment methods were evolved from traditional dial indicator coaxial adjustment method.The outer of the contour used as a benchmark to measure the axial and radial ruinous in these methods.However,these methods contain cylinder error of the shaft itself.To solve this problem,a method of using the double-layer one-dimensional Position Sensitive Detector (PSD) and laser was proposed.The laser should be fixed to the outside of the irregular rotating device,ensuring the two parts synchronous rotate ; the 6 one-dimensional PSD was divided to high and low 2layers which were placed in coaxial position with the reference axis.The laser sweep passing the PSD,when laser and the irregular device rotate synchronous,the light of spot position on the PSD can determine the irregular rotating workpieces axes and the reference axis position relationship,the device can be used to adjust coaxial in this way.
