SCREW ROTATION ADJUSTING DEVICE, CURVED SURFACE FORMATION DEVICE AND SCREW ROTATION ADJUSTING METHOD

To provide a screw rotation adjusting device which can shorten the time required for rotation adjustment of a screw when the rotation adjustment is repeatedly performed by a screwdriver.SOLUTION: A screw rotation adjusting device 1 comprises: a second axis 3 which can be connected with a first axis 2 having a screw structure 2c; a drive part 4 which rotates the second axis 3 around the shaft and moves in a direction making the second axis 3 abut against the first axis 2 and in a direction alienating it from the first axis 2; a controller 5 which controls the drive part 4; and a storage part 6 which stores a phase angle θ of the first axis 2 at the time of completing rotation adjustment of the first axis 2 around the shaft by the second axis 3. The controller 5 makes the drive part 4 connect the second axis 3 to the first axis 2 according to the phase angle θ of the first axis 2 at the time of completing rotation adjustment stored in the storage part 6 so that the first axis 1 can rotate by the second axis 3, and performs rotation adjustment of the first axis 2 around the shaft by rotating the second axis 3 in the state of the connection.SELECTED DRAWING: Figure 1 【課題】ドライバでネジの回転調整を繰り返し行う際に、ネジの回転調整に要する時間の短縮を図ることが可能なネジ回転調整装置を提供する。【解決手段】ネジ回転調整装置１は、ネジ構造２ｃを有する第１軸２に接続可能な第２軸３と、第２軸３を軸周りに回転させ、第２軸３を第１軸２と当接する方向及び第１軸２から離間する方向に移動させるための駆動部４と、駆動部４を制御する制御部５と、第２軸３による第１軸２の軸周りの回転調整完了時の第１軸２の位相角度θを記憶する記憶部６と、を備え、制御部５は、駆動部４に、記憶部６に記憶された回転調整完了時の第１軸２の位相角度θに応じて第２軸３を第１軸２に、第２軸３によって第１軸１の回転が可能な状態となるように接続させ、該接続させた状態で、第２軸３を回転させて第１軸２を軸周りに回転調整させる。【選択図】図１
