US 2021/0107069 A1 · Adaptive Work-Stop

Abstract

A work-stop assembly in a work-holding-collet is formed of a main work-stop body selectively mounted on the rear of the work-holding-collet and defining a longitudinal through passageway aligned with the collet mouth. First and second work-stop position adjusters allow coarse adjustment of the position of a work-stop element by one of the adjusters while the work-stop assembly is removed from the work-holding collet and allow more precise adjustment by the other adjuster after the work-stop assembly is mounted to the work-holding collet. One of the adjustments employs a slidable relationship between the adjuster and the passageway, and one of the adjusters carries the work-stop element for axial movement in the work-holding-collet to set an adjustable depth limit for a workpiece inserted from a workpiece-receiving mouth at the front of the work-holding-collet.

Dependent claims

In a work-holding-collet having an elongated body centered on a longitudinal center axis, having a workpiece-receiving mouth centered on said axis at a front end of said work-holding-collet and a rearwardly directed mount on the rear of the work-holding-collet, a work-stop assembly comprising:

a work-stop body, selectively connected to the work-holding-collet on said rearwardly directed mount, having a through passageway aligned with the central axis;
a first work-stop position adjuster and a second work-stop position adjuster, wherein said first work-stop position adjusters is selectively engaged in slidable relationship within said passageway and carries said second work-stop position adjuster for axial movement with the first work-stop position adjuster;
wherein, when the first work-stop position adjuster is engaged in the passageway, both the first work-stop position adjuster and the second work-stop position adjuster are centered on said longitudinal axis;
and
the second work-stop position adjuster carries a blocking element that is axially moveable with respect to the second work-stop position adjuster to, in use, establish an adjustable depth limit for reception of a workpiece into the work-stop body.

A work-holding-collet with a longitudinal front to rear axis, formed of a collet body with flared front body portion defining a ring of compressible jaws around a central work-receiving collet mouth, and with a tubular rear body portion located longitudinally rearward of the flared front body portion, comprising:

a work-stop body attached at the rear of said tubular rear body portion and defining a through passageway aligned with said work-receiving-collet mouth on said longitudinal front to rear axis;
and
a work-stop assembly connected to said work-stop body in said through passageway and aligned on said longitudinal axis with the work-receiving-collet mouth;
wherein said work-stop assembly comprises:
a rod-stop having a work-blocking front surface positioned forward of the through passageway;
a shank carrying said rod stop in forwardly extending position from the front end of said shank, the shank being engaged in the through passageway for movement on the longitudinal axis with respect to the work-receiving-collet mouth, placing the front end of the rod-stop within the tubular rear body portion of said work-holding-collet at a selected spacing behind the work-receiving-collet mouth for, in use, blocking further rearward movement of a workpiece inserted from the front of the work-receiving-collet mouth;
and wherein:
the work-stop assembly has an associated lock operable between the shank and the through passageway securing the shank in a selectable fixed longitudinal position with respect to the passageway.

A work-holding-collet with a longitudinal front to rear axis, formed of a collet body with flared front body portion defining a ring of compressible jaws arranged around a central work-receiving collet mouth, and with a tubular rear body portion located longitudinally rearward of the flared front body portion, comprising:

a work-stop body attached at the rear of said tubular rear body portion and defining a through passageway symmetrically aligned with the workpiece-receiving mouth on said longitudinal front to rear axis;
and
a work-stop assembly connected to the work-stop body in said through passageway and symmetrically aligned on the longitudinal front to rear axis with the collet mouth;
wherein the work-stop assembly comprises:
a rod-stop having a workpiece-blocking front surface;
a tube having an open front with a hollow-center carrying said rod-stop,
wherein the tube is engaged in the through passageway for longitudinal movement with respect to the workpiece-receiving mouth to position said workpiece-blocking front surface of the rod-stop at a selected spacing behind the workpiece-receiving mouth for, in use, blocking further rearward movement of a workpiece inserted in the front of the work-receiving collet mouth;
and
the tube having an associated tube lock operable between the tube and the through passageway securing the tube in a fixed position with respect to the passageway.
