摘要:
A tool exchanger wherein an exchange arm fixed on one end of a rotatable and axially slidable shaft is formed with a pair of semi-circular openings at opposite ends thereof. A pair of gripping plungers slidably received in the exchange arm are spring-biased toward opposite ends of the arm for gripping tools held in the semi-circular openings. A pair of guided pins are protruded respectively from the gripping plungers. A cam engageable with the guided pins is disposed in position to inwardly retract either of the gripping plungers which approaches a tool socket of a tool magazine, against the force of an associated bias spring, when the exchange arm is pivoted from a parked position toward a grip position for gripping tools received respectively in a machine tool spindle and the tool socket.
