Abstract
A system, in certain embodiments, includes a wedge-lock coupling configured to connect a jaw to an actuator arm of a chuck. The wedge-lock coupling includes a wedge portion having a path of travel between a release position and a lock position, and a locking direction along the path of travel gradually wedges the wedge portion between the actuator arm and the jaw.
Claims20
A system, comprising:
- a drive;
- a chuck rotatable by the drive, wherein the chuck comprises:
- an actuator arm;
- and
- a jaw;
- and
- a wedge-lock coupling between the actuator arm and the jaw, wherein the wedge-lock coupling comprises a wedge portion having a path of travel between a release position and a lock position, and a locking direction along the path of travel gradually wedges the wedge portion between the actuator arm and the jaw.
4 more elements
A system, comprising:
- a jaw comprising a first bore and a second bore, wherein the first bore is configured to couple to an arm of a work-holding chuck along a first axis, the second bore has a second axis disposed in a plane crosswise to the first axis, and the second bore gradually converges toward the first bore at a convergence angle of approximately 5 to 85 degrees;
- and
- a wedge-lock coupling disposed in the second bore, wherein the wedge-lock coupling comprises a wedge portion having a locking surface tapered relative to the second axis, the locking surface comprises a plurality of teeth elongated along the second axis, and the wedge portion is movable along the second bore.
A system, comprising:
- an actuator arm configured to couple to a work-holding chuck, wherein the actuator arm comprises:
- a first flat side wall having a first plurality of teeth oriented crosswise relative to an axis of the actuator arm, wherein the actuator arm is configured to retain a work-holding jaw in a first orientation via engagement with the first plurality of teeth;
- and
- a second flat side wall having a second plurality of teeth oriented crosswise to the axis of the actuator arm;
- wherein the actuator arm is configured to retain the work-holding jaw in a second orientation via engagement with the second plurality of teeth.
