Abstract
A machine tool equipped with an automatic tool changing device, including a tool support having a clamping mechanism for holding a cutting tool, a tool transfer device having a tool gripper for transferring the tool to and from the tool support at a tool change position, and a device for moving the tool support and the tool transfer device in a direction perpendicular to the axis of the tool held on the tool support, the tool changing device including a mechanism for converting a first relative movement of the gripper and the tool support toward each other, into a movement of the clamping mechanism for unclamping the tool from the tool support, and converting a second relative movement of the gripper and the tool support away from each other, into a movement of the clamping mechanism for clamping the tool to the tool support, wherein the gripper has a pair of jaws shaped for engagement with the tool held on the tool support before the tool is unclamped, and for permitting completion of the first relative movement at the tool change position after the tool is unclamped.
