Abstract
An method and apparatus for the assembly of motors utilizing curable adhesives. The method includes stations for: treating motor components with adhesive, assembling the motor components piece by piece, holding assembled motor components under compressive tension, overgramming components as needed, and an operational and life testing station. Integral to using the method are multi-position preload/cure fixtures. These fixtures include frame and base pieces. The frame holds assembled and adhesive treated motor components under compressive tension with spring loaded guide shafts during the curing process. The frame rests on the base. The base features nests which align the motor components for engagement with the guide shafts. The base also features a retractor bar to facilitate the insertion and removal of motor components. The base also features an overgramming means which supplies a brief overgramming pressure on the motor components to fully seat motor components. The present invention enables the rapid assembly and curing of motor components allowing efficient mass production of motors.
