a rotatable support sleeve or a rotatable support ring is mounted, from which the Protruding tool.
the setting tool operates as follows: First, a Blind rivet nut screwed onto the screwdriver by the electric motor the tool housing part and thus rotatably coupled screwing tool rotates. This "screwing" the blind rivet nut ends when the flange of Blind rivet nut the rotatable support sleeve at the head end of the tool housing part achieved, the rotation of the support sleeve prevents the blind rivet with large force is pressed against the support sleeve.
the rotationally fixed coupling between the tool housing part and the tool shaft released by the locking sleeve pneumatically is withdrawn, so that the balls from the pockets of the tool shaft can escape.
the anti-rotation device is effective by her Cylinder is extended, and the square of the tool shaft overlaps, so that the shaft is no longer rotatable. If the electric motor is now the ball nut of the Tool housing part rotates, the tool shaft with the screw tool axially moved back from the workpiece, resulting in the desired deformation point the blind rivet nut forms the desired bead and the blind rivet nut is tension resistant and is rotationally fixed to the workpiece.
the applied torque can be detected and calculated from the pulling force with which the blind rivet nut was anchored in the hole. About the angle, around which the ball nut has been turned, the pulling distance can be determined.
the anti-rotation device and the locking device by a common coupling device formed by the in a first axial Position of a coupling element the tool shaft rotation with the rotatable Tool housing part and in a second axial position of the coupling element can be coupled with a stationary housing part.
the tool shaft with a Multi-Kant approach preferably four-Kant approach, displaceable one accordingly shaped through hole of the coupling element passes through.
the coupling element is preferably with a pneumatic piston to the common connected axial displacement. It is also envisaged that the Coupling element has a front conical coupling surface, in the first axial Position of the coupling element against a corresponding conical surface of rotatable tool housing part is pressed, and a rearward conical Coupling surface in the second axial position of Coupling element against a corresponding conical surface of a stationary Housing part is pressed.
a drive shaft 2 of an electric motor not shown in the figure rotatable stored.
the electric motor is at the left in the figure, the end of the drive shaft. 2 arranged and attached to the housing part 1.
the drive shaft 2 has a portion 3, for example, the cross-sectional shape has a polygon.
a first pulley 4 whose Bore a matching with the outer contour of section 3 inner contour has, so that the pulley 4 rotatably connected to the drive shaft 2, but on sits longitudinally displaceable section 3.
a tool housing part 9 is rotatably mounted, with a second pulley is rotatably connected.
a timing belt 10 transmits the Rotary movement of the drive shaft 2 of the pulley 4 on the pulley of the Tool housing part 9.
a tool shaft 11 Within the tool housing part 9 sits concentrically a tool shaft 11, the at its right in the figure right end with a screw tool 12 rotatably connected is.
