POSITIONING DEVICE FOR STATOR CORE

To provide a positioning device for a stator core capable of positioning magnetic steel sheets stacked in a plate thickness direction without causing elastic deformation in teeth.SOLUTION: A positioning device 1 for a stator core 100 includes: a plurality of correction members 8 each having an insertion part which can be inserted into an adjacent tooth 103 of a plurality of teeth 103; and a movement mechanism 3 that moves the plurality of correction members 8 in a radial direction of a stator core body 102. The insertion part includes a circumferential contact part and a guide part. The circumferential contact part makes contact with a side surface positioned in the circumferential direction of the stator core body 102 in the adjacent tooth 103. The guide part extends to the outer side in the radial direction from the circumferential contact part, and the circumferential width in the insertion part becomes narrower as it goes towards the radially outer side.SELECTED DRAWING: Figure 3 【課題】ティースに弾性変形を生じさせることなく、板厚方向に積層された電磁鋼板の位置決めを行うことができる固定子コアの位置決め装置を提供する。【解決手段】複数のティース１０３のうち隣り合うティース１０３の間に挿入可能な挿入部を有する複数の矯正部材８と、前記複数の矯正部材８を前記固定子コア本体１０２の径方向に移動させる移動機構３を有し、前記挿入部は、周方向接触部と、案内部を有し、前記周方向接触部は、前記隣り合うティース１０３における前記固定子コア本体１０２の周方向に位置する側面にそれぞれ接触し、前記案内部は、前記周方向接触部からそれぞれ前記径方向外方に延び、且つ前記径方向外方に向かうにつれて前記挿入部における前記周方向の幅が狭くなる、固定子コア１００の位置決め装置１。【選択図】図３
