Abstract
A hydraulic chuck may include an expansion sleeve, a plurality of pistons, and an actuator ring. The expansion sleeve may include a bore. The plurality of pistons may be axially mounted in at least one piston chamber of the expansion sleeve. The actuator ring may be rotatably mounted relative to the expansion sleeve. The actuator ring may be configured to actuate the plurality of pistons in the at least one piston chamber to hydraulically expand the expansion sleeve to provide a varying clamping force within the bore.
Claims20
A hydraulic chuck comprising:
- an expansion sleeve comprising a bore;
- a plurality of pistons axially mounted in at least one piston chamber of the expansion sleeve;
- and
- an actuator ring rotatably mounted relative to the expansion sleeve, the actuator ring configured to actuate the plurality of pistons in the at least one piston chamber to hydraulically expand the expansion sleeve to provide a varying clamping force within the bore.
A method of hydraulically actuating a hydraulic chuck comprising:
- rotating an actuator ring of the hydraulic chuck to actuate a plurality of pistons axially mounted within at least one piston chamber of an expansion sleeve of the hydraulic chuck;
- and
- expanding the expansion sleeve to provide a varying clamping force within a bore of the hydraulic chuck.
