Abstract:
An apparatus for releasably holding a toolholder with a shank having lockable surfaces and a releasable surface, the apparatus comprising:(a) a tool support member having a forwardly facing surface and a bore along a longitudinal axis, wherein the bore intersects the forwardly facing surface and extends rearwardly therefrom for receiving the shank of the toolholder; (b) a rotatable actuating bolt positioned within the tool support member along a radial axis (R1) relative to the longitudinal axis and having a first end with a bolt locking segment having a bolt locking surface, wherein the actuating bolt further includes a releasing segment having a releasing surface for abutting and urging forwardly the releasable surface of the shank to eject the toolholder shank from the tool support member; (c) an actuating nut rotatably fixed within the tool support member, threadably secured to a second end of the actuating bolt and having a nut locking segment having a nut locking surface; and (d) wherein rotation of the actuating bolt in a locking direction causes the actuating nut to be drawn to the bolt first end thereby drawing together the nut locking surface and the bolt locking surface such that they engage the toolholder lockable surfaces and lock the toolholder within the tool support member.
