    摘要： A rotary tapered tool holder includes a body or shank including a front contact portion and a rear contact portion. An adapter sleeve is disposed about a portion of the shank. The adapter sleeve includes slits that allow radial expansion and contraction of the adapter sleeve. The adapter sleeve includes an inner surface formed at a first non-zero taper angle with respect to a longitudinal axis of the shank, and an outer surface formed at a second non-zero taper angle with respect to the longitudinal axis of the shank. The second taper angle is different than the first taper angle such that an interference fit between the shank and the inner surface of the adapter sleeve forces the outer surface of the adapter sleeve into positive contact with a tapered bore of a spindle of the rotary tapered tool holder.

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

    摘要： A clamping apparatus for detachably connecting a tool unit to a tool supporter with increased holding force is provided. The clamping apparatus includes a housing, a pair of opposing locking spheres within the housing, a cylindrical canister member mounted within the housing that is matable with an insert-supporting tool unit and which has a pair of opposing apertures in its sidewalls for conducting the locking spheres from a locking to an unlocking position, and a lock rod reciprocally movable within the interior of the canister member along an axis A and having opposing cam portions for radially moving the locking spheres through the canister apertures into wedging engagement with opposing angled walls of sphere receiving openings in the tool unit. To increase the mechanical advantage of the wedging action between the locking spheres and the angled walls of the tool unit, the aperture walls of the canister member are angled with respect to a line R extending radially from the lock rod axis A to reduce the angle between the aperture wall and the tool unit wall. Such angling increases the force of wedging and locking engagement between the locking spheres and the angled walls of the tool unit. In the preferred embodiment, the aperture walls are angled 15° with respect to the aforementioned radial line R, thereby increasing the holding force of the clamping mechanism by 30%.

    摘要： A self-locking clamping apparatus is provided for coupling a tool unit to a tool supporter. The clamping apparatus includes a pair of locking spheres, a canister member that is matable with the tool unit and which includes a pair of opposing apertures for admitting the locking spheres, and a lock rod reciprocally movable within the canister member along an axis and having opposing ramp portions for radially moving the locking spheres through the canister apertures into locking engagement with the tool unit. The ramp portions are inclined at a small angle of approximately 5.degree. with respect to the axis of movement of the lock rod to render the lock rod self-locking as a result of stiction between the surfaces of the ramp portions and the locking spheres. The small angle of the ramp portions allows the use of a small, lightweight pneumatic actuator which may be powered by shop air. Finally, a biasing mechanism in the form of one or more coil springs prevents the lock rod from being shaken out of a locked position from externally applied vibration.

    摘要： A cutting tool assembly (1) clamping mechanism (5) which secures a cutting insert (3) for performing cutoff, grooving, slotting, and profiling operations. The clamping mechanism (5) has resilient upper and lower clamping jaws (7, 9) for receiving and securing the insert (3). The cutting insert (3) has front and top faces (13, 15) that define a cutting edge (21) at an intersection thereof, a back face (25), and adjacent proximal and distal bottom faces (27, 29) contiguous with said front and back faces (13, 25) that define an angular lower seating portion (30). The lower clamping jaw (9) of the clamping mechanism (5) includes proximal and distal pocket surfaces (59, 67) forming an angularly recessed jaw portion that is complementary in shape to the angular seating portion (30) of the insert (3). The distal pocket surface (67) of the lower clamping jaw (9) is oriented with the proximal pocket surface (59) to form a stop for limiting the extent that the insert (3) may be received between the clamping jaws (7, 9). This orientation further redirects a component of the cutting force (F) on the insert (3) toward the top face (15) thereof in order to wedgingly engage the top face (15) of the insert (3) against the top pocket surface (45) of the upper clamping jaw (9), thereby enhancing the clamping force that the jaws (7, 9) apply to the insert (3).
