A method and apparatus for shaping the winding end turns of a stator assembly wherein the outside diameter of the end turns is first engaged by a set of alternate segments in a circular array and is thereafter engaged by a set of intervening segments of the array while the first set remains engaged. The motion and configuration of the segments avoids the risk of pinching a wire of the winding by eliminating relative circumferential closing movement between adjacent segments. The inside diameter of the end turns is shaped by an expandable mandrel assembly that includes interengaged shoes that have a sliding movement in expansion and contraction that also avoids the risk of pinching strands of the winding.

Apparatus for end turn shaping

A lead straightening and trimming apparatus for the leads of electrical components such as stators. The apparatus includes a pallet having positioning posts which position the stators on the pallet and also position coils within the stator. The apparatus also includes a rotating helical pick-up tool which is movable between a retracted position and an extended position adjacent to a component supporting pallet having lead retaining posts. The pick-up tool operates to capture the free ends of leads extending from posts provided by the pallets. Upon retraction, the pick-up tool moves the associated free ends of the leads to a partially straightened gripping position. The apparatus also includes a combined gripper straightening and cutting apparatus which grips the associated lead adjacent to the pallet post with a force insufficient to cut the lead. Retraction of the gripper straightens the portion of the lead extending from the retaining post of the pallet. The gripper is then released to release tension in the lead. The straightener cutter then cuts the lead along the straightened portion at a predetermined distance from the post.
