Patent ID: 8702081

Claim:
A clamping device comprising: at least three jaws for clamping a plurality of elongated workpieces with the workpieces forming predetermined angles therebetween, wherein each of at least two jaws comprises clamping surfaces oriented to correspond to a respective angle; at least two arms, each arm having a respective jaw of the at least two jaws connected thereto at a first endportion thereof; a holding element having the at least two arms pivotally movable mounted thereto such that the at least two jaws are movable between an open position for placing the clamping device and a clamping position for clamping the workpieces; and, an actuator connected to the at least two arms, the actuator for moving the at least two arms and for holding the at least two arms in the clamping position, wherein the actuator comprises: an actuator element; at least two coupling elements, each coupling element being pivotally movable mounted to the actuator element and pivotally movable mounted to the respective arm; and a screw mechanism for pivotally moving the at least two arms by changing a distance between the actuator element and the holding element; and, wherein each of the at least two arms is pivotally movable mounted at a midportion thereof and interacts with the actuator at a second endportion thereof.
