ABSTRACT:
A push-type collet and seat assembly has a push-type collet including an elongated cylindrical body having a rear end portion, a front end portion tapering inwardly towards a front end thereof, an opening extending longitudinally through the collet, and slots extending longitudinally through at least the front end portion in communication with the opening to divide the front end portion into separated compressible portions. A workpiece is inserted into the opening of the collet and extends forwardly of the compressible portions. A seat partially receives the collet therein so that, when the collet front end portion is forcibly wedged against the seat, the compressible portions are squeezed against the workpiece to fix the workpiece relative to the collet. A stop is disposed a predetermined distance forwardly of the seat and adapted to receive the workpiece front end so that, when the workpiece front end is forcibly wedged against the stop, the stop limits forward movement of the workpiece. A drive generally simultaneously moves the workpiece forwardly against the stop to forcibly wedge the workpiece front end thereagainst and moves the collet forwardly against the seat to forcibly wedge the collet front end portion thereagainst, such that the workpiece abuts against the stop prior to the collet fixing the workpiece relative to the collet.
