Abstract
A tool for installing or removing a collet head, which has a plurality of spring loaded collet segments, from a collet body, comprises a body having an axis, a base and a skirt extending from the base. A member is operably secured to the body and axially movable relative thereto. A plurality of arms are pivotally secured at each of one of their end portions to each one of a plurality of recesses disposed in the skirt. The other end portion of each arms is movably secured to one end of the member such that when the member moves axially, the other end of each of the arms move with the member while the one end of each of the arms pivots in the recesses. A pin is operably associated with each arm for cooperating with its respective hole in the collet head such that each pin moves radially relative to the axis when the member moves axially relative to the body, whereby the collet head is compressed or expanded for engaging or disengaging the collet head from the collet body.
