PROBLEM TO BE SOLVED: To provide a center jig device for laminated core assembly, in assembly work of a laminated core for stator that is configured by laminating toric or divided segment-like unit material, which is available for lamination work of the unit materials in different inner diameter sizes and can easily pull the laminated core away after completion.SOLUTION: A number of inner claw rails K4... are fitted to a mandrel K1 that is installed in an upright state, through radius conversion mechanisms K2... formed from a number of slide units 20... installed radially in a movable state in a radial direction. A number of inner claw rails K4... are adjusted and locked at positions in an inner circumferential radius of unit materials W... subjected to lamination. Next, the laminated core is formed by laminating the unit materials W... in such a manner that inner edges of the unit materials W... are inscribed and supported at multiple points by a number of inner claw rails K4... and after the laminated core is completed, the laminated core can be pulled away by moving a number of inner claw rails K4... to a center side.SELECTED DRAWING: Figure 1 |
