Abstract: An automatic measuring apparatus includes an inside-diameter measuring unit that measures the inside diameter of a workpiece, a robot arm part, and a control unit. The inside-diameter measuring unit is installed with the tip side facing upward. A cone-shaped guide cone is provided at the tip of the inside-diameter measuring unit. A workpiece stopper is attached to the outside of the inside-diameter measuring unit. A support surface, which serves as a placing surface on which the workpiece is placed, is supported by a spring, and the inclination and position of the support surface changes to follow a change in the posture and position of the workpiece.

Abstract: There is provided an inside-diameter measuring unit capable of automating inside-diameter measurement and a control method for automatic inside-diameter measurement. An inside-diameter measuring part is supported by a support frame part via a floating joint part. The floating joint part includes a rotation-allowing mechanism part and a translation-allowing mechanism part. A measuring head part of the inside-diameter measuring part is inserted into a hole by a robot arm part. The inside-diameter measuring part adjusts its position and posture autonomously by the reaction force when a contact point pushes against the inner wall of the hole to align the axis of the inside-diameter measuring part with the axis of the hole. An electric inside-diameter measuring unit can automatically measure the inside diameter of a hole.
