Abstract
An apparatus for adapting toolholders (10) which are specifically designed for use with machine tools having quick change tooling systems so that such toolholders may be used with machine tools not equipped with such systems. The apparatus secures to the toolholder shank (45) and provides an intermediate element enabling the toolholder (10) to be secured to such machine tools.

An apparatus to adapt a toolholder (10) for mounting to a base member (75) in which the toolholder (10) is designed for use with a quick release system and is comprised of a forward end (15) for receiving a tool (20), a rearwardly facing abutment face (40), a tubular shank (45) extending rearwardly away from said forward end (15) and having a longitudinal axis (56), said shank (45) perforated by perforations (55) at spaced locations, a forwardly facing concave contact surface (60) in each of said perforations (55), said forwardly facing concave contact surface (60) extending forwardly while extending away from the inner surface of said tubular shank (45) toward the outer surface of said tubular shank (45) and at least one slot (53) within said shank (45) by which said toolholder (10) may be held nonrotatably, said apparatus comprising:
- a) adapter canister (200) capable of being inserted within the toolholder shank (45), said adapter canister (200) having:
- i) a forward end (202) and a rearward end (204);
- ii) depressions (205) located upon the canister (200) in positions corresponding to said perforations (55) such that in the inserted position the depressions (205) are generally aligned with said shank perforations (55);
- and
- iii) a protruding key portion (220) on the canister (200) for engaging said slot (53) within said shank (45) when said adapter canister (200) is inserted into said toolholder shank (45);
- b) a locking element (210) positioned within each perforation (55) and depression (205) to provide a coupling and to provide rigidity along the longitudinal axis (56) between said toolholder (10) and said adapter canister (200) by capturing said locking elements (210) between the respective depressions (205) and the toolholder perforation forwardly facing concave contact surfaces (60) when said adapter canister (200) is urged away from said toolholder (10);
- c) toolholder support member (230) having a forwardly facing abutment face (280) for contact with said toolholder rearwardly facing abutment face (40) and an opening (285) extending rearwardly therefrom to receive said toolholder (10) and said adapter canister (200) with said locking elements (210), said opening (285) having an opening first portion (290) to receive said shank (45), an opening second portion (300) to receive and hold nonrotatably said adapter canister (200) and an opening third portion (310) from which said toolholder (10) and said canister (200) with said locking elements (210) may be urged into said toolholder support member (230);
- and
- d) means for urging the canister (225) into and out of said toolholder support member (230).
An apparatus to adapt a toolholder (10) for mounting to a base member (75) in which the toolholder (10) is designed for use with a quick release system and is comprised of a forward end (15) for receiving a tool (20), a rearwardly facing abutment face (40), a tubular shank (45) extending rearwardly away from said forward end (15) and having a longitudinal axis (56), said shank (45) perforated by perforations (55) at spaced locations, a forwardly facing concave contact surface (60) in each of said perforations (55), said forwardly facing concave contact surface (60) extending forwardly while extending away from the inner surface of said tubular shank (45) toward the outer surface of said tubular shank (45) and at least one slot (53) within said shank (45) by which said toolholder (10) may be held nonrotatably, said apparatus comprising
- a) an adapter canister (200) capable of being inserted within the toolholder shank (45), said adapter canister (200) having:
- i) a forward end (202) and a rearward end (204);
- ii) generally spherical depressions (205) located upon the canister (200) in positions corresponding to said perforations (55) such that in the inserted position the depressions (205) are generally aligned with said shank perforations (55);
- iii) a protruding key portion (220) on the canister (200) for engaging a slot (53) within said shank (45) when said adapter canister (200) is inserted into said toolholder shank (45);
- b) a spherical locking element (210) positioned within each perforation (55) and each depression (205) to provide a coupling and to provide rigidity along the longitudinal axis (56) between said toolholder (10) and said adapter canister (200) by capturing said locking elements (210) between said depression (205) and the toolholder forwardly facing concave contact surface (60) when said adapter canister (200) is urged away from said toolholder (10);
- c) a toolholder support member (230) having a forwardly facing abutment face (280) for contact with toolholder rearwardly facing abutment face (40) and an opening (285) extending rearwardly therefrom to receive said toolholder (10) and said adapter canister (200) with said locking elements (210), said opening (285) having an opening first portion (290) to receive said shank (45), an opening second portion (300) to receive and hold nonrotatably said adapter canister (200) and an opening third portion (310) from which toolholder (10) and canister (200) with locking elements (210) may be urged into said toolholder support member (230);
- and
- d) means for urging said canister (225) into and out of said toolholder support member (230) comprised of a rod (225) having a forward end (227) and a rearward end (229) wherein said rod (225) is threaded at each end (227, 229) and the rod forward end (227) is mateingly threaded in a threaded bore (235) within the canister rearward end (204) and the rod rearward end (229) is mateingly threaded in a threaded bore (235) with corresponding threads within opening third portion (310) of the toolholder support member (230) such that rod (225) rotation causes relative movement between the toolholder (10) and the toolholder support member (230) to secure or release the toolholder (10) from the toolholder support member (230).
