Abstract
A system, in certain embodiments, includes a cutting tool, a drive and a chuck rotatable by the drive. The chuck includes multiple actuator arms, multiple jaws and multiple spring-loaded lock pins coupling the respective jaws to the respective actuator arms.
Claims19
A system, comprising:
- a cutting tool;
- a drive;
- a chuck rotatable by the drive, wherein the chuck comprises:
- a plurality of actuator arms;
- a plurality of jaws;
- and
- a plurality of spring-loaded lock pins coupling the respective jaws to the respective actuator arms by blocking movement of the respective jaws along respective longitudinal axes of the respective actuator arms, wherein compressing each spring-loaded lock pin enables movement and removal of each respective jaw from each respective actuator arm along the respective longitudinal axes.
4 more elements
A system, comprising:
- a chuck configured to hold a workpiece, the chuck comprising:
- a chuck body;
- and
- an actuator arm coupled to the chuck body, wherein the actuator arm comprises an annular wall surrounding a cavity, a recess along an interior surface of the annular wall near a base portion of the cavity, and a tool opening through the annular wall adjacent to the recess, wherein the recess comprises a cylindrical hole at an angle into the interior surface of the annular wall, and the angle is greater than 0 degrees and less than 90 degrees;
- wherein the cavity is configured to receive a jaw, the recess is configured to receive a spring-loaded lock pin biased from the jaw toward the annular wall, and the tool opening is configured to receive a tool to bias the spring-loaded lock pin away from the recess.
2 more elements
A system, comprising:
- a workpiece holding jaw comprising a passage, wherein the passage extends at an angle from an end portion to a side portion of the workpiece holding jaw;
- and
- a spring-loaded lock pin disposed in the passage, wherein the spring-loaded lock pin is biased outwardly from the side portion of the workpiece holding jaw, the spring-loaded lock pin is configured to block movement of the jaw relative to an actuator arm via engagement with a recess in the actuator arm, and compressing the spring-loaded lock pin enables movement and removal of the jaw from the actuator arm.
