ABSTRACT:
A machine for driving a pin into a hole in a work piece. The pins are fed by gravity in a continuous succession from a pin supply to a passage extending through a pin receiving rotor. With a pin in the rotor, the rotor is turned through a selected angle to bring the pin and the passage through the rotor into alignment with a pin driving punch. Upon actuation of the punch, the pin is driven from the rotor into a passage in an adjacent aligned sliding pin guide. Movement of the pin through the pin guide temporarily ceases when the pin encounters a resilient stop. Continued movement of the punch then moves the pin guide and the pin therein until the nose of the pin guide engages the work piece. The punch, continuing to move through the passage in the now stationary pin guide, drives the pin past the resilient stop and into the aligned hole in the work piece. Upon withdrawal of the punch, the pin guide aided by a spring returns to it original position adjacent the rotor. When the punch has cleared the rotor, the rotor is then rotated back to its original position ready to receive the next pin. The operation is then repeated to drive the next pin into another hole in the work piece which has been positioned to be aligned with the punch and the passage through the pin guide.
