ABSTRACT:
A coupling system (1) is provided for lockably coupling together machine tool components that comprises a male coupling (3) having a recess (19) at a distal end that includes follower surfaces (24), and female coupling (9) having an opening (31) disposed along its longitudinal axis for receiving the distal end of the male coupling (3), and a pair of opposing jaw members (12) pivotally mounted in the opening (31) and having cam surfaces (44) engagable with the follower surfaces (24) of the male coupling (3). The system (1) includes a drive train (13) for pivotally moving the jaw members (12) apart in order to interengage the cam (44) and follower surfaces (24) of the female (5) and male (3) couplings that includes an axially movable, ball-shaped element (52) disposed in opposing recesses (50) present in the jaw members (12) for prying the jaw members (12) apart, a pair of opposing wedge members ( 58) for moving the ball-shaped drive element (52) axially toward the free ends of the jaw members (12), and a screw (64) having right and left hand threads on either of its ends for moving the wedge members (58) toward and away from one another. The drive train (13) generates high clamping forces between the male (3) and female (5) couplings in a small envelope and with a large degree of mechanical advantage.
