<p>Clamping device for a machine duplicating keys, with a body (1) lodging two jaws (2,3) apt to transversely tighten a key (4,4A), wherein said two jaws (2,3) can be approached and/or spaced by the activation of only one operation means (10,15), and a bridge (20) is arranged apt to tighten the key (4) against said body (1) through a movement (Y) orthogonal to the reciprocal motion (X) of said jaws (2,3); these ones are provided with respective inclined planes with a symmetrical inclination, and said bridge is provided with two inclined planes (20A,20B) each having the same inclination of a respective of the inclined planes (2A,3A) of said two jaws. Elastic means (35,36) are arranged which are able of pushing said bridge (20) against said two jaws (2,3) along a direction (Y) orthogonal to the direction (Y) of reciprocal tightening of the two jaws (2,3), and the bridge (20) is provided in its outer portion with a relief (23) capable of tightening the key against said body.</p> |
