Abstract
An injection shuttle system is disclosed for fabricating stator core assemblies. Injection tooling and a stator core are selected and positioned on a shuttle means at a selection station for moving to coil loading stations and a transfer station. The injection tooling is positioned, aligned and manipulated relative to a winding machine at each coil loading station for disposing winding turns thereon. At the transfer station, the injection tooling is transferred to a wedge guide housing of a turntable arrangement which includes wedge making and injection stations. A stator height adjustment arrangement is provided for adjusting the wedge making and injection stations in accordance with the axial length of the core. The injection tooling is moved or indexed to the wedge making stations where insulating wedges are fabricated and inserted into wedge guides of the wedge guide housing. The injection tooling is then moved to the injection station where the core is interfitted with the tooling by a core transfer assembly. An injection mechanism at the injection station then injects or transfers the winding turns and insulating wedges into axially extending slots of the core. The end turns …
