Non-contact sensor position adjusting structure for measuring shafts

The invention discloses a sensor position adjusting mechanism for non-contact measurement of shaft parts. The sensor position adjusting mechanism for non-contact measurement of the shaft parts comprises an equipment measuring basis, a fixing assembly, a translation assembly and a rotating assembly, wherein the fixing assembly is fixedly installed on the equipment measuring basis; the translation assembly is installed and fixed on the fixing assembly in an up-down lifting adjustment mode; and the rotating assembly is installed on the translation assembly in a relatively rotating mode. According to the sensor position adjusting mechanism for non-contact measurement of the shaft parts provided by the invention, two adjustments of translation and rotation are alternately used, so that the final error can be converged to a relatively small value, and high-precision adjustment of a measurement point is realized; and the structure provided by the invention is beneficial to reducing the process requirements on proces
