Abstract
An apparatus is disclosed for releasable holding a toolholder shank having a lockable surface and a releasable surface utilizing an actuating bolt. The actuating bolt is reciprocally movable along an axis to engage one side of the shank for locking the toolholder within the support member and an opposing side of the shank for releasing the toolholder from the tool support member.
Claims45
An apparatus for releasably holding a toolholder, the apparatus comprising:
- a) a tool support member having a forwardly facing surface, a bore along a longitudinal axis and a passageway, wherein the bore intersects the forwardly facing surface and extends rearwardly therefrom for receiving the toolholder and wherein the passageway extends through the tool support member and intersects the longitudinal axis, and;
- b) an actuating bolt extending all the way through the tool support member within the passageway and is reciprocally movable between a locking position and a releasing position along a radial axis relative to the longitudinal axis for locking or ejecting a shank into or from the tool support member, wherein the actuating bolt has a locking segment for abutting and urging rearwardly the locking surface of the shank of the toolholder to lock the toolholder within the tool support member.
An apparatus for releasably holding a shank having a lockable surface and a releasable surface, the apparatus comprising:
- a) a support member having a forwardly facing surface and a bore along a longitudinal axis, wherein the bore intersects the forwardly facing surface and extends rearwardly therefrom for receiving the shank and;
- b) an actuating bolt extending all the way through the support member and reciprocally movable between a locking and a releasing position along a radial axis relative to the longitudinal axis for locking or ejecting the shank into or from the support member, wherein the actuating bolt has a locking segment for abutting and urging rearwardly the lockable surface of the shank to lock the shank within the support member, wherein the actuating bolt is positioned within a passageway which extends through the support member along the radial axis thereby defining first and second apertures within the support member with the second aperture diametrically opposed to the first aperture.
A toolholder for mounting in a bore of a tool support member with a longitudinal axis and a forwardly facing surface and for being secured within the bore by an actuating bolt movable in a reciprocating motion along a radial axis, wherein the bolt has a releasing segment and a locking segment, the toolholder comprising:
- a) a forward end upon which a cutting tool is capable of being mounted;
- b) a shank adjacent to and connected to a rearwardly facing abutment face and extending rearwardly away from the forward end;
- and
- c) wherein the shank is perforated by a lockable perforation and a releasable perforation at two circumferentially spaced locations, wherein the lockable perforation has a lockable surface which is urged rearwardly by the locking segment of the actuating bolt moved along the radial axis in one direction and wherein the releasable perforation has a releasable surface which is urged forwardly by a releasing surface of the actuating bolt moved in an opposite radial direction.
A toolholder for mounting in a bore of a support member with a longitudinal axis and a forwardly facing surface and for being secured within the bore by an actuating bolt movable in a reciprocating motion along a radial axis, wherein the bolt has a releasing segment and a locking segment, the holder comprising:
- a) a forward end;
- b) a shank adjacent to and connected to the rearwardly facing abutment face and extending rearwardly away from the forward end;
- and
- c) wherein the shank is perforated by a lockable perforation and a releasable perforation at two circumferentially spaced locations, wherein the lockable perforation has a lockable surface which is urged rearwardly by the locking segment of the actuating bolt moved in a radial direction and wherein the releasable perforation has a releasable surface which is urged forwardly by a releasing surface of the actuating bolt moved in an opposite radial direction.
A combination for mounting a toolholder into a bore in a forwardly facing surface of a tool support member, said combination comprising:
- a shank on a rearward portion of the toolholder extending rearwardly into the bore of the tool support member;
- wherein the shank is perforated by a lockable perforation and a releasable perforation at two circumferentially spaced locations;
- a lockable surface in the lockable perforation which is capable of being engaged by a locking segment of the actuating bolt to lock the shank within the toolholder;
- a releasable surface in the releasable perforation which may be engaged by a releasing surface of the actuating bolt to eject the shank from the toolholder;
- and
- an actuating bolt having a locking segment and a releasing segment wherein the actuating bolt is reciprocable between a locked position in which the locking segment of the actuating bolt engages the lockable surface of the shank lockable perforation and a released position in which the releasing segment of the actuating bolt engages the releasable surface of the shank releasable perforation.
