Abstract:
The clutch device performs two functions: release of the clutch at the rear end position of the pulling head and slipping of the clutch at the home position. The blind rivet fastening device (1) is equipped with a spindle clutch (61) axially movable with respect to the spindle (14) and integrally rotated, and a nut clutch (62) integrally formed with the ball screw nut (44). The spindle clutch can move in the axial direction and can release from the nut clutch. In addition, the spindle clutch has a first segment unit (61C); one end of the first segment unit is a vertical plane (61D) and the other end is a slanted plane (61E). The nut clutch has second segment units (62C) of complementary shape. When the pulling head (28) reaches the rear end position, the engagement of the clutch is released. When the pulling head returns to the home position, the inclined faces of the clutch slip with each other.
