Abstract
A device for attaching a tool to the end of a robot arm includes a collet having a truncated conical body with a radially outwardly extending flange formed at a larger end and a cylindrical holder having a tapered aperture for receiving the conical body of the collet. The collet has radially outwardly extending threads formed on the periphery of the flange to engage the threaded interior of a tubular collar. A radially inwardly extending flange on the collar engages a radially outwardly extending flange on the holder to retain the collet conical body in the tapered aperture thereby providing precise X-Y location. The flange on the collet is attached to a face place which is in turn attached to a tool, and an end of the holder is attached to a mounting flange which in turn is attached to an end of a robot arm. Means for preventing relative rotation between the collet and the holder includes a pair of longitudinally extending slots and cooperating key, or a pair of circular apertures and a cooperating pin.
