Abstract

The tool changer of the present invention is characterized by a drawbar having a gripper at one of its ends and incorporating a tensioner at its opposite end that is released after full retraction of the milling sleeve to release the drawbar by opening this way the gripper to release a tool holder from it. The released tool holder can be replaced by a new tool holder and the sleeve can be extended by causing the tensioner to be actuated to tension the drawbar, in order to make the gripper be closed around the new tool holder. In the preferred embodiment, the tensioner is formed by a group of angled rods that normally protrude in the axial direction of the drawbar to hold said drawbar in its retracted or tensioned position and are partially crushed to release the bar traction to its extended position. The changing apparatus may also incorporate a safety feature that renders inoperative the release of the angled levers during rotation of the spindle, thereby preventing inadvertent release of the tool holder during a milling operation.
