Abstract
An expanding, inner diameter gripping collet assembly for a pick-off spindle. An arbor base is connected to the pick-off spindle and is moveably connected to a moveable arbor. The moveable arbor engages and is driven by the pick-off spindle nose. The moveable arbor has motion-translating cam surfaces on one end that engage corresponding surfaces on one end of an expanding collet. A drawplug having motion-translating cam surfaces that engage corresponding ones on the other end of an expanding collet is inserted through the moveable arbor and secured into the arbor base. The collet assembly also includes an ejector housing, in which an ejector is positioned for sliding movement. A compression spring biases the ejector forwardly.
