Patent ID: 7243414

Claim:
A device for gripping and transferring a ring of electrical conductors in the form of pins used to produce a pin winding for a rotating electrical machine stator, the gripping device comprising: a support element comprising a frame having an axis, and a plurality of levers for gripping the ring, wherein each of the plurality of levers comprises a control arm, a gripping arm having an end element configured to grip the ring, and an intermediate section between the control arm and the gripping arm; wherein the intermediate sections of the plurality of levers are pivotally mounted on the frame, the pivotal mounting comprising a position for gripping the ring and a release position; at least one control element configured to pivot the plurality of levers, the at least one control element comprising a cone disposed coaxial to the frame, and having a surface inclined relative to the axis of the frame, wherein the at least one control element is configured to axially move the cone in the frame; wherein the ends of the control arms of the plurality of levers are maintained in support against the inclined surface of the cone; wherein the plurality of levers pivot in response to the axial movement of the cone; and wherein the gripping device is adapted to seize the ring in a first device for forming the ring, and transfer the ring to a second device by inserting the ring in the support element of the winding.
