Claims (1)
ボルトの頭部と係合する係合穴を設け、この係合
穴に係合したボルトを、前記回転軸の回転によつ
てボルト穴に螺合して締付けるナツトランナにお
いて、前記回転軸の係合穴にボルトの頭部と接触
してボルトの軸方向に超音波を送信し、ボルトの
先端からの反射波を受信する超音波発受信器を設
け、この超音波発受信器を超音波ボルト軸力計に
接続したことを特徴とするナツトランナ。 An engagement hole that engages with the head of a bolt is provided at the tip of a rotating shaft that rotates in conjunction with the drive mechanism, and the bolt that is engaged with this engagement hole is inserted into the bolt hole by rotation of the rotating shaft. In a nut runner that is screwed together and tightened, an ultrasonic transducer transmits an ultrasonic wave in the axial direction of the bolt by contacting the head of the bolt in the engagement hole of the rotating shaft and receives a reflected wave from the tip of the bolt. and this ultrasonic transmitter/receiver is connected to an ultrasonic bolt axial force meter.
