ABSTRACT:
A tool changer for use in a transfer machine includes a pallet movable to a station in front of a machining unit, and a tool support mounted on the pallet for releasably supporting a tool. The machining unit is movable by an actuator toward the tool support to receive the tool from or release the tool onto the tool support. When the machining unit is advanced toward the tool support, the pallet is lowered by another actuator to release the tool support from supporting the tool, which has been held by the machining unit. Prior to transfer of the tool from the tool support to the machining unit, the tool is held down against the tool support by a clamp arm pivotably mounted on a clamp frame fixedly placed on the pallet. The clamp arm is angularly actuatable to release the tool in response to the movement of the machining unit toward the tool support.
