Abstract

A tooling apparatus having a main somewhat hollow yoke-like housing adjustably positionable in micrometer increments relative to a supporting base member which may be readily and fixedly attached to the lathe bed. The yoke housing is provided with an enlarged opening for receiving a rotating assembly including a plurality of radially adjustable jaw members adapted for engaging the outer surface of an elongate work piece for retention of the work piece within the jaws thereof. The jaw members may be adjusted in micrometer increments for precise positioning of the work piece relative to the opening thereof, and relative to the lathe chuck, either centrally relative thereto, or offset therefrom. The housing and rotating jaw assembly are sealed and provided with bearings therein to permit rotation while enabling passage of fluid through hollow openings therein for enabling lubrication and cooling to permit high speeds of rotation 20 during machining of a work piece supported by the lathe chuck and the apparatus.

Dependent claims

In a tooling apparatus for use with a machining lathe to support a work piece at a position displaced from the driven lathe chuck, the combination comprising:

base means for attachment to the lathe;
a yoke means adjustably secured to said base means, said yoke means having an enlarged diameter opening with bearing receiving surfaces formed therein and passage means in thermally conductive relation therewith;
an assembly rotatably mounted on said yoke means, said assembly having first and second plate members having interconnected hub portions within the enlarged opening of said yoke means to define, in conjunction with said yoke means, an annular compartment, said assembly having an enlarged diameter opening in the interconnected hub portions for passage therethrough of a work piece;
radially adjustable jaw means received within slot means in the surface of one of said first and second plate members for clamping engagement with the surface of the work piece;
bearing means received within said annular compartment and intercoupling said yoke means and said assembly;
means for sealing said annular compartment for enabling the providing of lubrication fluid to said bearing means;
means for pre-loading said bearing means;
and
means for providing cooling fluid to said passage means within said yoke means for enabling flow of cooling fluid therethrough to cool the parts during rotation of said assembly, said assembly being driven by said work piece as said driven chuck is rotated.

In a tooling apparatus for use with a machining lathe to support a work piece at position displaced from the driven lathe chuck, the combination comprising:

a base assembly for attaching to the lathe;
a yoke member having a portion thereof adjustably received on said base assembly, said yoke member having an enlarged diameter opening with generally parallel opposing edges, the peripheral surface of the yoke member defining said opening having first and second annular shoulder means formed thereon,
an assembly having first and second members with generally identically configured washer-shaped flange portions and integrally formed interconnecting hub portions, the inner surfaces of said flange portions engaging said opposing edges of said yoke member with said interconnecting hub portions passing through said opening for rotatably mounting on said yoke means, said flange portions having an enlarged diameter opening for passage therethrough of a work piece, the interior surfaces of said first and second members and said annular shoulder means defining an annular compartment;
annular bearing means received on said annular shoulder means within said annular compartment and operatively engaging the interior surface of said interconnecting hub portions for enabling rotation of said assembly relative to said yoke member;
means interengaging said hub portions and said bearing means for pre-loading said bearing means;
a plurality of radially adjustable jaw means on one of said flange portions of said assembly for clamping engagement with the surface of the work piece;
means for sealing said annular compartment for enabling the providing of lubrication fluid to said bearing means;
and
cooling fluid passage means within said yoke means for enabling flow of cooling fluid therethrough to cool the parts during rotation of said assembly, said assembly being driven by said work piece as said driven chuck is rotated.
