By lowering the cam 15 attached to the board 11 to the base 10 and pressing the inclined surface 13f of the jig 13 with the inclined cam surface 15a of the cam 15, the divided cores 1 move in the radial direction so as to reduce the diameter of each other, This is a stator core assembling apparatus in which protrusions 6 of adjacent split cores 1 are press-fitted into concave grooves 7 of adjacent split cores 1 and the split cores 1 are connected in a ring shape.

[0003]

However, in the above-described stator core assembling apparatus, the cam 15 attached to the movable platen 11 is moved down to the base 10 and the divided cores 1 are connected in a ring shape. Height is required, and the device becomes large. That is, it is difficult to use the stator core assembling apparatus in a place where there is no allowance in the height direction.
Therefore, there is a demand for a stator core assembling apparatus for a generator / motor which does not require a space in the height direction of the device and can assemble the stator core even in a place where there is no room in the height direction.

It is an object of the present invention to provide a generator / motor stator core assembling apparatus capable of assembling a stator core without selecting a space for an assembling place, particularly in a place where there is no height.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a yoke portion of a split core comprising an arc-shaped yoke portion and a pole portion extending from the center of the yoke portion toward the center of the arc. In a stator core assembling apparatus for a generator / motor in which a fitting projection is provided at one end and a fitting recess is provided at the other end, and a fitting projection is fitted to an adjacent fitting recess, a ring-shaped stator core is assembled. A core supporter for supporting each of the split cores, a base for supporting these core supporters so as to be movable in a radial direction, and a rotatable cam groove mounted on the base, and a spiral cam groove formed on the splitter. , A locking portion for locking the core support to the cam groove, and a rotating means for rotating the rotary plate.

A plurality of divided cores are respectively supported by a core support, a rotating plate is rotated by a rotating means, and a hook portion of the core support is moved in a radial direction by each cam groove of the rotating plate. The ring-shaped stator core is assembled by fitting the fitting protrusions into the fitting recesses adjacent to each other.

Conventionally, the height of the apparatus is increased due to the adoption of the vertical slide method, but the present invention employs the horizontal rotation method. That is, the stator core assembling apparatus is configured such that the core supporting base, the base, the rotating plate having the spiral cam grooves as many as the number of the divided cores, the locking portion for locking the core supporting base in the cam grooves, and the rotating plate are rotated. By using the rotating means, the device could be made significantly shorter.
