半割りとなしたマスタねじ１６と、該マスタねじ
の直径を変える開閉手段１４と、前記ナツトＮを
軸方向に移動可能且旋回可能に支持する治具２，
３と、該治具に接触して前記ナツトＮを旋回させ
るとともに一定トルクが作用したとき回転を切り
離す駆動手段とを含み、マスタねじに螺合された
ナツトの旋回にともなう軸移動でナツト端面がマ
スタねじの肩面に当接された位置をねじの切り始
めとして検出することを特徴とするナツトのねじ
切り始め位置検出装置。 A master screw 16 that is divided into halves and has a shoulder surface 16a that the end surface Na of the nut abuts, an opening/closing means 14 that changes the diameter of the master screw, and supports the nut N so as to be movable and pivotable in the axial direction. Jig 2,
3, and a driving means that contacts the jig to rotate the nut N and disconnects the rotation when a constant torque is applied, and the nut end face is rotated by the axis movement accompanying the rotation of the nut screwed into the master screw. A nut thread cutting start position detecting device, characterized in that the position where the master screw is brought into contact with the shoulder surface of the master screw is detected as the thread cutting start position.
