Abstract
A shaft precision automatic measurement device for motors is provided that is able to automatically measure shaft precision of a motor. A shaft precision automatic measurement device () for a motor () includes: a gripping mechanism () that grips the shaft (); a first contact-type displacement sensor () that is able to measure a position of the flange face () by contacting to follow the flange face (); a second contact-type displacement sensor () that is able to measure a position of the fitting face () by contacting to follow the fitting face (); a rotary mechanism () that causes the device main body () to rotate in a state gripping the shaft () by the gripping mechanism () and executing measurement by way of the respective displacement sensors; a displacement data acquisition part () that acquires displacement data of the flange face () and displacement data of the fitting face (); and a measurement part () that measures center runout and face deflection of the shaft () based on the respective displacement data acquired by the displacement data acquisition part ().
