Method and device for inserting a plurality of phase insulators in the cavities of the stator of a dynamo-electric machine.

摘要

A plurality of phase insulators are inserted in the cavities of the stator of a dynamo-electric machine by means of an insertion device which includes a plurality of guide blades (8) displaced circumferentially around a central axis (9) and an insertion member (10) slidable between the series of guide blades (8) and having a circumferential series of axial grooves in its outer surface in which the various blades (8) are engated. The insertion member (10) is disposed initially in a rest position in which it allows a phase insulator to be positioned above the guide blades (8), after which it is moved to an operative position so as to cause the phase insulators to slide along the guide blades (8) and to be inserted in the cavities of the stator. Before the phase insulators are disposed above the guide blades (8) at least some of them are moved from their normal operative positions to positions spaced radially towards the outside in which the arrangement of the phase insulators above the guide blades (8) is particularly simple so as to enable this to be carried out by automatic assembly equipment as well.
