Abstract

1,021,582. Rotary impact tool. FRANKFURTER MASCHINENBAU A.G. Oct. 8, 1963 [Feb. 2, 1963], No. 39546/63. Heading B3N. A torque limiting rotary impact screw-driver or nut runner comprises a counting mechanism which initiates means for interrupting the energy supply to the drive, after an optionally adjustable number of impacts have occurred. Air is supplied to motor 21 from a hose 2<SP>1</SP> through a conduit 3, a sliding control valve 5, a conduit 8, a stop valve 37, and a conduit 17. The rotor of motor 21 has a worm 22 thereon which co-operates with a worm wheel 23, and a split internally screwed sleeve 25 secured to the worm wheel co-operates with an axially movable, but non rotary, screwed spindle 29. Motor 21 also drives an epicyclic gear train 44 mounted in a carrier 47, which gear co-operates with a fixed internal gear 48 to drive a hammer 49 and anvil 50. In operation with motor 21 running, sleeve 25 rotates and moves spindle 29 to the right, Fig. 1 (not shown), and after a predetermined number of revolutions the end 28 of the spindle strikes valve 37 which moves to the right and shuts off the air supply to the motor, which then stops. Trigger 4 is released, and valve 5 moves, so that air is supplied to move a piston 41 to the right. The conical end of this piston disengages sleeve 25 from spindle 29, which is then moved to the left by a spring 27 until it engages an adjusting screw 31, ready for the next operation.
