ABSTRACT:
A collet-stop assembly for fixing the position of a work-piece or tool ("item") intended to be held immobile by and within a collet during machining operations. The assembly includes a stop-collar for gripping a stop-unit to be placed in direct contact with the item, and a collar-retainer used ensure that the stop-unit is held immobile with respect to the collet. The collar-retainer is screwed into the collet and includes a tapered section into which a tapered section of the stop-collar is drawn. In the Preferred Embodiment of the invention the stop-collar is formed of three separate jaws that when drawn into the collar-retainer by means of cap screws passing through the collar-retainer squeeze against the stop-unit. The basic collar-retainer design permits it to be manufactured so that the distances it extends, respectively, to the outside of the collet and down into the collet are very short; that is, it has small external and internal profiles. All manipulations of the assembly are done at one end of the collar-retainer and require only a single tool to complete. In the Preferred Embodiment, this tool is a small-gauge Allen key used to tighten the cap screws. The device simplicity depends in part on the cap-screw-tightening action resulting in rotational immobility of the stop-unit and work-piece with respect to the collet, even though the collet-stop assembly is made only finger-tight prior to the cap-screw-tightening.
