ABSTRACT:
A tool holder assembly for use with a workpiece feed mechanism and machining mechanism for forming a new surface on a workpiece is described. The workpiece feed mechanism has slot surfaces extending defining an opening which includes bearing surfaces. The tool holder assembly comprises a removable support including a plate adapted to be received in the slot. The plate has surfaces defining a socket and has shoulder surfaces adapted to engage the bearing surfaces. The tool holder assembly includes a tool receptacle which is adapted to receive the workpiece. At least one detent is provided which includes detent surfaces adapted to engage the socket in the plate. The detents are mounted on the workpiece feed mechanism for movement between a locking position where the detent surfaces of the detent are engaged with the socket, and a release position where the detent surfaces of the detent are spaced from the socket to afford sliding movement of the support within the slot. A spring is present that biases the detent toward the locking position and biases the shoulder of the plate outward toward engagement with the bearing surfaces to thereby hold the support on the workpiece feed mechanism while the new surface is formed on the workpiece by the machining mechanism. Also present is an actuation mechanism for moving the detent mechanism from the locking position to the release position and for overcoming the secure engagement between the shoulder surfaces of the plate and the bearing surfaces of the slot before the support is slid within the slot.
