Abstract
A workpiece gripping apparatus comprising a base, two centering jaws displaceably guided on the base so as to be movable toward and away from one another, and an actuator jaw displaceably guided on both of the centering jaws. The actuator jaw is movable toward and away from the base, with movement of the actuator jaw causing movement of both of the centering jaws, which are adapted to center a workpiece between them.
Claims11
A workpiece gripping apparatus for an indexing chuck, comprising:
- a base mounted on the indexing chuck;
- two centering jaws displaceably guided on said base so as to be movable toward and away from one another, wherein said centering jaws are each a monolithic piece and are adapted to center a workpiece between them;
- and
- an actuator jaw displaceably guided on both of said centering jaws, wherein said actuator jaw is a monolithic piece that is movable toward and away from said base, and wherein movement of said actuator jaw causes movement of both of said centering jaws.
1 more element
A method of self-centering a workpiece in an indexing chuck, including the steps of:
- mounting a base on the indexing chuck;
- placing a workpiece on the base;
- and
- effecting movement of two centering jaws that are each a monolithic piece and are displaceably guided on said base toward one another by moving an actuator jaw that is a monolithic piece and is displaceably guided on said centering jaws toward said base, wherein said movement of said centering jaws toward one another effects centering of said workpiece between them.
