るボルト締付は力制御装置。An ultrasonic measuring device that uses ultrasonic waves to measure the length of the bolt when it is tightened before and when it is tightened by the nut runner drive. The ax calculation circuit section converts the bolt length into the regular bolt elongation amount, and the above normal bolt elongation amount output from the calculation circuit section is written in advance! The controller is equipped with a comparison circuit that compares and calculates the set elongation amount with the set elongation amount, and when the bolt elongation amount and the elongation amount set value match when tightening the member with the thread bolt and nut, the controller sends a signal from the controller. A bolt tightening force control device characterized in that the drive of the nut runner is automatically stopped in response to an output stop signal.
