ABSTRACT:
A hollow body and drawbar coupler connect to form a collet adaptor with external configuration matching that of a commonly available draw-style spring collet. A receptacle at the anterior portion of the body holds the adapted collet. Tension applied by a machine tool drawbar is transmitted through the draw bar coupler and draw tube to actuate the adapted collet. A stop sleeve within the adaptor body limits the draw stroke, and thus the clamping force applied to the collet. The collet is threaded inward or outward by a machine operator to adjust clamping force. A keying ring within the adaptor maintains radial position of the collet via a friction mechanism. Differentially threaded engagements of the adaptor drawbar with the adapted collet and the body provide a self contained means for clamping the collet when the adaptor is removed from the machine tool. An optional unitary, cylindrical protuberance provides an extended nose for improved access to a chucked workpiece.
