    摘要: An apparatus for releasably holding a tubular toolholder shank includes a tool support member; a canister disposed within the tool support member; a lock rod movable within the tool support member in a reciprocating motion for pulling the tubular toolholder shank into a locked position and for releasing the tubular toolholder shank to an unlocked position; and at least two locking elements engaging the lock rod so that movement of the lock rod causes the locking elements to extend outward to engage the tubular toolholder shank. The lock rod includes a relief cavity extending rearward from a forward end of the lock rod. The lock rod has a maximum outer diameter and the relief cavity has a maximum diameter. A ratio of the maximum diameter of the relief cavity to the maximum outer diameter of the front portion of the lock rod is greater than approximately 1 to 4.

    摘要: An apparatus (200) for pneumatically amplifying the force acting upon a lock rod (95) to retain a toolholder (10) within a toolholder receiving member (65) has a spindle (205) extending from the toolholder receiving member and at least two in-line dual acting piston/cylinder modules (215) within a cavity within the bore (207) of the spindle. Each module (215) has a piston (220) within an associated cylinder (225) and wherein the lock rod (95), through a drawbar (230), is attached to the piston (220) of each module (215) such that when each module is pressurized, the combined force of all of the pistons is applied to the lock rod. The invention is also directed to a method for achieving this task.

    摘要: A toolholder (20) comprises a body portion (32), a support member assembly (33) mounted to the body portion and an insert-receiving cartridge (36) removably received in the support member. The insert-receiving cartridge (36) includes a pocket (38) for mounting a cutting insert (40) thereon. The support member assembly (33) includes a bore and the insert-receiving cartridge (36) includes a shank capable of being received in the bore. The combination of the insert-receiving cartridge (36) and the cutting insert (40) forms a cutting tool for a particular cutting operation. In one embodiment, the cutting tools are radially mounted to a side periphery of the body portion (32) such that the vertical axis of the cutting tool is substantially parallel to the longitudinal axis (L) of the toolholder (20).

    摘要: An apparatus (10) is disclosed for releasably holding a toolholder shank (30) having a lockable surface (90, 95) and a releasable surface (185) utilizing an actuating bolt (20) with an associated threaded actuating nut (75). When the actuating bolt (20) is rotated in a locking direction, the actuating nut (75) is drawn onto the bolt (20) thereby clamping against the lockable surfaces (90, 95) of the toolholder shank (30). When the actuating bolt (20) is rotated in the releasing direction, a releasing segment (170) acts upon the toolholder (25) thereby ejecting it from the tool support member (15).

    摘要: 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) engageable 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 inter-engage 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.
