摘要： A reference range of tightening torques is predetermined relative to the rotation angle of a threaded member as tightened up normally. In tightening up a nut on an externally threaded member, the tightening torque is detected by a torque sensor every time the nut is rotated through a specified angle, and whether the tightening torque relative to the rotation angle is within the reference range is judged by a microcomputer. The result of judgment is indicated by a light-emitting diode and a buzzer.

摘要： A tightening device comprises an upper plate (1), a lower plate (3) disposed below the upper plate (1) in parallel thereto, a nut rotating gear (4) supported by the lower plate (3) so as to be rotatable in a horizontal plane, and a spur gear (27) provided on an underside of the upper plate (1) and meshable with the gear (4) for rotating the gear (4). The upper plate (1) has a portion (2) fittable to a flange of an externally threaded member for preventing the rotation of the threaded member, while the nut rotating gear (4) has a portion (5) fittable to a nut. With the nut manually tightened on the threaded member in advance, the flange fitting portion (2) of the upper plate (1) is fitted to the flange, the nut is fitted in the fitting portion (5) of the nut rotating gear (4), and the spur gear (27) is thereafter rotated, whereby the nut rotating gear (4) is driven to tighten up the nut on the threaded member.
