ABSTRACT:
The invention is concerned with an improvement in a machine tool gripping assembly of the type which comprises a housing with a bore therewithin and a collet slidable toward and retractable from a spindle facing end portion of said bore, the collet having extending from a spindle facing end thereof a plurality of resilient leaves each attached at one end to said collet and separated at a spindle gripping end thereof, each of said leaves having a first annular cam surface adjacent said spindle gripping end thereof, said surface being formed at a selected angle with respect to the longitudinal axis of said collet. The improvement comprises a floating collar in said bore adjacent the spindle gripping end of said leaves, said collar having a second annular cam surface at generally the same angle as said first cam surface, an inner generally cylindrical surface of said collar urging said spindle gripping ends of said leaves towards one another when said collet is retracted into said bore and an outer generally cylindrical surface of said collar floating clear of the spindle facing end portion of said bore. The improvement further includes means supported by said bore adjacent said spindle facing end portion thereof for stopping said collar from sliding into said bore. Also, the improvement includes means for preventing said collar from sliding out of said spindle facing end portion of said bore, the ends of said collar floating clear of said stopping means and said preventing means.
