Claims

[Scope of claim for utility model registration] Driver stand 3 that moves up and down by the operation of cylinder 2
A motor 4a is fixed to the driver base 3 so as to move up and down integrally with the input disc 5, which rotates in response to the rotation of the motor 4a, a planetary cone 6 that frictionally engages with the outer periphery of the input disc 5, and a planetary cone 6 that frictionally engages with the outer periphery of the input disc 5. A driver bit 8 is connected to the cam disk 7 so as to rotate together with the cam disk 7, and an arm 12 is rotatably locked at one end on the driver stand 3 side. , a speed change ring 9 is rotatably disposed at the upper end of the arm 12 and frictionally engaged with the outer periphery of the planetary cone 6,
Further, the speed change ring 9 is biased toward the high speed side by the spring 13, and the screw tightening completion detecting section is provided, and the output signal of the screw tightening completion detecting section is used to drive the motor 4a.
In an automatic screw tightening machine equipped with a control section for the motor 4a that stops normal rotation of the motor 4a and slightly reverses the motor 4a, rotation of the cam disk 7 in one direction is blocked between the cam disk 7 and the driver bit 8. This automatic screw tightening machine is characterized by having a one-way clutch 19 arranged therein.
