Publication number: 20240035816Abstract: An automatic measuring device includes a micrometer including a spindle that moves forward and backward to be brought into contact with or away from a workpiece and a displacement detector unit that detects displacement of the spindle, and an automatic operation unit that automates the forward and backward movement of the spindle by power. The automatic operation unit performs a first forward-movement step of moving the spindle forward to bring the spindle into contact with the workpiece, and a contact determination step of determining the contact between the spindle and the workpiece in the first forward-movement step. In the contact determination step, the spindle is determined to be in contact with the workpiece when a change in a position of the spindle detected by the displacement detector unit in the first forward-movement step becomes equal to or less than a predetermined contact determination threshold.Type: ApplicationFiled: July 27, 2023Publication date: February 1, 2024Applicant: MITUTOYO CORPORATIONInventors: Keita OGAWA, Shuji HAYASHIDA, Masashi YAMAJI

Publication number: 20230324161Abstract: 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.Type: ApplicationFiled: March 22, 2023Publication date: October 12, 2023Applicant: MITUTOYO CORPORATIONInventors: Masashi YAMAJI, Yuhei TAKATSU, Chihiro YAMAMOTO
