Abstract
An adapter for holding a workpiece to be machined in an accurately located axial position can include a main sleeve having an interior wall defining a passage extending therethrough with at least one inner surface angled inwardly toward a centerline of the passage, a collet engageable within the passage and supporting a positive axial location stop, an axially and radially moveable wedge interposed between the main sleeve and a workpiece to be processed, and a rotatable sleeve engageable with the wedge for accurately locating the workpiece to be processed by radially grasping the workpiece to be processed and axially moving the workpiece into engagement with the positive axial location stop.

An adapter for holding an elongate workpiece to be machined in an accurately located axial position comprising:
- a main sleeve having an interior wall defining a passage extending therethrough with at least one inner surface angled inwardly toward a centerline of the passage;
- a collet engageable within the passage and supporting a positive axial location stop;
- an axially and radially moveable wedge interposed between the main sleeve and a workpiece to be processed;
- and
- a rotatable sleeve engageable with the wedge for accurately locating the workpiece to be processed with respect to the main sleeve by radially grasping the workpiece to be processed and axially moving the workpiece into engagement with the positive axial location stop.
An adapter for holding an elongate workpiece to be machined in an accurately located axial position comprising:
- a main sleeve having an interior wall defining a passage extending therethrough with at least one inner surface angled inwardly toward a centerline of the passage;
- a collet engageable within the passage and supporting a positive axial location stop, the collet including an elongate body supporting the positve axial location stop adjacent one longitudinal end and at least one axially extending slot located on a periphery of the elongate body;
- an axially and radially moveable wedge having an elongate body interposed between the main sleeve and a workpiece to be processed, the at least one axially extending slot through the collet allowing radially inwardly extending passage of the at least one inwardly facing, axially extending, workpiece-engaging surface formed on the wedge located on a periphery of the elongate body, the workpiece-engaging surface moveable radially as the elongate body of the wedge moves axially;
- and
- a rotatable sleeve engageable with the wedge for accurately locating the workpiece to be processed with respect to the main sleeve by radially grasping the workpiece to be processed and axially moving the workpiece into engagement with the positive axial location stop.
An adapter for holding an elongate workpiece to be machined in an accurately located axial position comprising:
- a main sleeve having an interior wall defining a passage extending therethrough with at least one inner surface angled inwardly toward a centerline of the passage;
- a collet engageable within the passage and supporting a positive axial location stop, the collet including an elongate body supporting the positve axial location stop adjacent one longitudinal end and a plurality of axially extending slots spaced angulary around a periphery of the elongate body;
- an axially and radially moveable wedge having an elongate body with a central passage, a threaded portion adjacent to one longitudinal end of the body, the wedge interposed between the main sleeve and a workpiece to be processed, the plurality of axially extending slots through the collet allowing radially inwardly extending passage of a corresponding plurality of inwardly facing, axially extending, workpiece-engaging surfaces formed on the wedge spaced angularly aroung a periphery of the elongate body, the workpiece-engaging surface moveable radially as the elongate body of the wedge moves axially;
- and
- a rotatable sleeve engageable with the wedge for accurately locating the workpiece to be processed with respect to the main sleeve by radially grasping the workpiece to be processed and axially moving the workpiece into engagement with the positive axial location stop.
