Abstract
A collet chuck assembly includes a chuck body carrying a collet retaining ring for receiving the threaded rear end of a standard collet. The collet retaining ring is secured to the chuck body and held against both axial and radial movement relative to the chuck body by a plurality of radially extending fasteners having inner, tapered portions received by correspondingly tapered holes in the retaining ring. A longitudinally or axially displaceable closing sleeve compresses the collet jaws when the sleeve is moved inone axial direction and releases the jaws when moved in the other axial direction. Axial displacement of the closing sleeve is effected by a collet actuator including a plurality of longitudinal fingers extending through openings in the collet retaining ring and having end portions configured to interlock with a correspondingly configured mating portion of the collet closing sleeve. In a preferred embodiment the fingers and mating portion of the closing sleeve include releasable interlocking arcuate flanges and grooves.
