US 6,206,382 B1 · Equalizing power chuck

Abstract

An equalizing power chuck includes a body, a plurality of work engaging jaws, and a plurality of rocker arms carrying the jaws. The rocker arms extend axially along an axis and have a mounting portion at one axial end for the jaws and an end portion at the other axial end. The equalizing power chuck also includes a plurality of swivel mountings connecting the rocker arms to the body, a plurality of slide members receiving the end portions of the rocker arms, a reciprocal actuator disposed centrally of the rocker arms, and a plurality of carrier members pivotally secured to the actuator. Each of the carrier members operatively cooperates with a pair of the slide members such that reciprocatory movement of the actuator moves the carrier members and correspondingly the slide members to move pairs of the jaws simultaneously relative to each other to engage a work-piece therebetween and allows the pairs of the jaws to pivot until a pressure exerted on the work-piece by the work engaging jaws is equalized.
