ABSTRACT:
Armatures for electric machines of the direct current type conventionally include a slotted core and commutator on a common shaft. This apparatus is for winding coils in the core slots and for connecting the coil leads to the commutator. The commutator is provided with bars and risers and the risers with slots. The apparatus includes a supporting frame and a support on the frame for holding an armature in winding position. Lead-connecting mechanism is mounted on the frame adjacent to the armature support in juxtaposition to the commutator of the armature for locating two coil leads in two riser slots, respectively. The lead-connecting mechanism is further supported for limited rotational movement about the axis of the armature shaft. Coil-winding mechanism is provided on the frame for winding a coil on the core of the armature.
The lead-connecting mechanism includes a coil lead guide device having two lead-aligning sections laterally spaced a distance corresponding to the spacing between two adjacent slots in the commutator riser. The lead-aligning sections are disposed radially opposite the riser with said sections being in alignment with the two adjacent riser slots. Further, means are provided for locating the two end leads of the coil wound on the core in the lead-aligning sections in radial alignment with the two riser slots, respectively. Two lead-inserting devices as a part of the lead-connecting mechanism are mounted for selective movement into and out of said two riser slots for inserting the coil leads into the slots, respectively.
