Device for gripping and transferring a ring of electrical conductors which is used to produce a winding and a winding-production system employing one such device

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.
