Hydraulic device for actuating plates of mechanical grip parts, intended especially for machine tools, characterized essentially because it is composed of a hydraulic rotary cylinder, adapted by one facing the output shaft of the machine, while the other is directly associated with the gripping plate of the parts to rotate together, which cylinder is provided with a piston capable of moving axially inside the plate and act on the gripping jaws of the pieces, whose displacement in one direction or another will be determined by the continuous feeding of a hydraulic circuit conveniently disposed in a body surrounding the cylinder and between which are provided running tracks that reduce friction both bodies facilitating piro the cylinder with respect to the housing.
