Clamping device

Clamping device (1) for holding a semifinished product in position with respect to a support base, which comprises:

• at least one first clamping assembly (2), which is intended to be removably fixed to one of said support base and said semifinished product and it comprises at least one first connection body (3);
• at least one second clamping assembly (4), which is intended to be removably fixed to the other of said semifinished product and said support base and it comprises at least one second connection body (5);
• said first and second connection body (3, 5) being mechanically engaged to mutually translate one with respect to the other with at least one degree of freedom on a first reference plane (X) between a plurality of first adjustment positions;
• a first locking mechanism (6), which is mechanically associated with said first and with said second connection body (3, 5) and it can be switched between a first constraint condition, in which it locks said first and second connection body (3, 5) into one of said first adjustment positions, and a first release condition, in which it frees said first and second connection body (3, 5) to mutually translate one with respect to the other on said reference plane (X);
• a first actuation piston (7), which is slidably inserted into a first guide chamber (8) obtained on said first connection body (3) in order to translate along a movement direction (Z) transversal to said reference plane (X) between a first actuation position, in which it maintains said first locking mechanism (6) in said first constraint condition, and a second actuation position, in which it maintains said first locking mechanism (6) in said first release condition;
• a first elastic member (9), which is inserted into said first guide chamber (8) and it is provided to force said first actuation piston (7) into one of said first actuation position and said second actuation position;
• a first actuator member (10), which is provided to move said first actuation piston (7) into the other of said first and second actuation position, making said first elastic member (9) yield elastically.
