<p>A clamping device with articulated levers, particularly for locking workpieces, includes a body (12) in which an axially sliding stem (14) is mounted, a main shaft (32) rotatable about a rotation axis (A) transverse to the stem (14) and connected to the stem (14) by means of a first toggle articulation mechanism (26, 30), and a first and second swingable clamping arm (34, 42) that can simultaneously rotate between respective back rest and advanced operative positions. The movement of the second arm (42) is controlled by a linkage (50, 54, 56) including a second toggle articulation mechanism. The second arm (42) is connected to a rotatable secondary shaft (38) coaxial with respect to the main shaft (32), in such a way that both arms (34, 42) swing about the same rotation axis (A).</p> |
