Abstract
An apparatus for assembling a stator core having a plurality of radially disposed and radially movably jigs for holding the segmented cores. Vertically movable cams are provided vertically downwards on an upper vertically movable plate. By lowering the movably plate, the jigs are pushed radially inwards, thereby causing the plurality of segmented cores circumferentially to approach each other. The projection of each segmented core is fit by press fitting into the groove of the adjoining segmented core in the circumferential direction, thereby connecting the segmented cores together.
Claims2
An apparatus for assembling a stator core, said stator core having a plurality of segmented cores, each of said segmented cores having an arcuate yoke portion, a pole portion extending diametrically inwards from said yoke portion, and a tooth portion on a diametrically inner end of said pole portion, said yoke portion having a projection and a groove on circumferential one end and the other end, respectively, thereof, said segmented cores being assembled to form a stator core by circumferentially connecting said segmented cores by fitting a projection in one of adjoining segmented cores into a groove in the other of said adjoining segmented cores, said apparatus comprising:
- a bed;
- a movable plate which is provided above said bed so as to be movable up and down;
- a plurality of jigs for holding said plurality of segmented cores radially disposed on said bed so as to be radially movable;
- and
- cam means downwardly provided on a lower surface of said movable plate so as to push each of said plurality of jigs radially inwards in synchronization with a downward movement of said movable plate,
- wherein said downward movement of said movable plate is in a direction perpendicular to a direction in which each of said jigs is pushed by said cam means.
