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: An automatic measuring apparatus includes a measuring device that measures a dimension of a workpiece, the measuring device including a movable element that is displaceable with respect to a fixed element and moves forward and backward to be brought into contact with or away from the workpiece, and a displacement detection part that detects a displacement or position of the movable element, and an automatic operation part that automates the forward/backward movement of the movable element by power. A workpiece holding part that holds the workpiece in such a manner that a position and posture of the workpiece is changed at a pressure lower than a predetermined measurement pressure set in advance in the measuring device when the movable element is brought into contact with 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.

Abstract: There is provided an automatic measuring apparatus that automates an inexpensive and easy-to-use contact-type measuring device. An automatic measuring apparatus includes a measuring device including a movable element that is displaceable with respect to a fixed element and moves forward and backward to be brought into contact with or away from a workpiece, and a displacement detection part that detects a displacement or position of the movable element, and an automatic operation part that automates the forward/backward movement of the movable element by power. When the movable element is brought into contact with the workpiece, vibration is applied directly or indirectly to at least one of the workpiece and the measuring device in such a manner that contacting surfaces of the workpiece and the measuring device are in close contact with each other by changing a relative position and posture between the workpiece and the measuring device.
