Abstract
A measuring device for checking mechanical pieces either while stationary or rotating which includes a first feeler substantially fixed with respect to a support and in alignment with a measuring head having a second feeler and supported by the support, a commutation unit containing a shaft and cams for changing the support and an electrical unit for detecting and visually recording the diameters and geometrical errors. In a first working condition the support of the measuring device can oscillate in order to allow both the first and second feeler to remain in contact with the piece to be gauged. The commutation unit allows for a change from the first working condition for measuring diameters of the work piece through the first and second feelers to a second working condition for measuring geometrical errors of a piece through the second feeler.
