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.
Claims10
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 chuck shaped and configured to be rotated by a drive, wherein the chuck comprises:
- a jaw;
- and
- a wedge-lock coupling configured to couple the jaw to an actuator arm, wherein the wedge-lock coupling comprises:
- a wedge portion having a path of travel between a release position and a lock position, wherein a locking direction along the path of travel is configured to gradually wedge the wedge portion between the actuator arm and the jaw;
- an axis along the path of travel, wherein the wedge portion comprises a locking surface tapered relative to the axis;
- and
- a first plurality of teeth disposed on the locking surface, wherein the first plurality of teeth are configured to engage a second plurality of teeth of the actuator arm when the wedge portion is in the lock position.
