Abstract
Improved mandrel, of the type comprising a substantially cylindrical main body that at one end has an extension that can be coupled to the rotating head of a machine tool, while at the opposite end there are linked guides by which the tool carriage is slidable, essentially characterized because it comprises: an externally graduated body, rotating around the main body, coupled internally to conventional toothed bodies that transmit and convert their rotation into linear displacements of the tool carriage, and provided with a coaxial annular groove in the bottom of which there is a continuous plurality of conical concavities tangents with each other; a ring installed between an annular protruding flange of the end of the main body that is linked to the guides of the carriage and said graduated body, said ring being of a vernier faced with the graduation of the graduated body and the ring itself being provided with means of immobilization of said graduated body with respect to the main body; a secondary body having a tubular portion fitted in the annular groove of the graduated body, said tubular portion being provided with a series of through conduits perpendicular to the bottom of that groove, in each of which conduits there is housed a pivot provided at one end a conical tip normally retracted thanks to a spring wound on the pivot itself and capable of fitting into one of those concavities, and also provided, at the opposite end, with a ball projecting partially outside the secondary body; a concentric disc superimposed on the secondary body, carrying a small inclined plane, capable of being immobilized with respect to the rotation of the secondary body in order to procure the successive passage of the emerging balls of said secondary body under said inclined plane to cause the thrust of the respective pivots against a conical concavity; and a concentric crown and associated to said disc carrying the inclined plane.
