ELECTROMECHANICALLY-OPERATED CLAMPING FIXTURE, PARTICULARLY FOR CLAMPING SHEET-METAL VEHICLE PARTS
The fixture comprises a plurality of clamping devices (10) and an electromechanical actuation system arranged to control the clamping devices (10). Each clamping device (10) comprises a clamping member (20) that is mobile between a first position, or closed position, and a second position, or open position, and a translating control member (22) that is operatively connected to the clamping member (20) to control the movement of the same between the first and second positions. The electromechanical actuation system comprises an electric motor (14), a rotary actuation member (48) arranged to be driven to rotate by the electric motor (14) and, for each clamping device (10), a rotary input member (24), a motion, conversion mechanism (26, 28) arranged to convert the rotary motion of the input member (24) into a translational motion of the control member (22) of said clamping device (10), and an elongated and flexible mechanical transmission member (16) arranged to transmit torque from the rotary actuation member (48) to the rotary input member (24) of said clamping device (10). Each elongated and flexible mechanical transmission member (16) has a first end (44) that is torsionally coupled, directly or indirectly, to the rotary input member (24) of the respective clamping device (10), and a second end (46) that is torsionally coupled, directly or indirectly, to the rotary actuation member (48).
