ABSTRACT:
A transfer device in an automatic tool exchanger is provided wherein a pair of transfer arms, each formed with semicircular openings at respective opposite ends thereof, are secured respectively to one of the ends of first and second support shafts and extend mutually in parallel relation and transversely of the support shafts. The support shafts are co-axially mounted to be bodily axially moved by a reciprocation drive device and also to be rotated by a first rotational drive device in the same direction. A second rotational drive device for rotating the support shafts in opposite directions is composed of a rotational cylinder with two rotors connected respectively to the support shafts, so that tools are maintained reliably gripped by the semicircular openings during tool transfer movements.
