One part is provided with couplings for assembling on a machine-tool, and the other is provided with a presser and a drill guide. Another spring which is suitable for keeping the tool centered is included and a relative stroke between the two sliding parts is longer than the drilling stroke of the tool.

Abstract: An operating head for automatic machine tools consists of a fork (2) having a shaft (6) rotatably mounted to a support arm (1) for rotating around an axis (C). A motor chuck (5) is rotatably mounted between the arms of the fork and rotates around an axis (A). Axis (A) is orthogonal to axis (C). Drive systems (10,9,8) control the rotation of the fork (2) around the axis (C) by directly engaging the shaft (6). In order to transmit rotational motion for the fork (2) around support arm (1) and for the positioning motion of the motor chuck (5), a hypoid toothed crown wheel (8,13) and pinion (9,14) are used.

Abstract: A machine tool head comprises a fork fitted to a support having a plurality of degrees of freedom, and a tool unit hinged to the fork. The tool unit contains equipment designed to control a tool carrier so that it can traverse along an axis, and equipment designed to perform controlled tool rotation around that axis. The tool carrier is in the form of a shaft which is mounted on a bushing to which a crown gear is connected. The crown gear engages a first pinion which meshes with a second pinion that is connected to a gear motor. The gear motor and the first and second pinions are mounted as a unit on a hinge to the structure which supports the bushing and a biasing mechanism is provided for urgening the first pinion into meshing engagement with the crown gear.
