<p>Coupling device for the transmission of the movement to rotatable toolholder units mounted on automatic turrets, comprising coupling means disposed in correspondence with the sole working position of the tool, and adapted for performing axially translatory movement for engagement with the rotatable toolholder unit, under the action of actuating means for the translatory movement and control means for the axial blocking of the turret, said coupling means being furthermore adapted for revolving about their own axis under the action of means for generating and transmitting the movement, in this manner causing coupling of the transmission of the movement to the sole tool disposed in the working position, with the turret blocked and with rotation axes of the toolholder unit and of the coupling means coinciding in a position of alignment. <IMAGE></p> |
