Assembly tool for laminated stator packs
Abstract
Abstract THE INVENTION RELATES TO AN ASSEMBLING MACHINE FOR ASSEMBLING PACKS OF STAMPED LAMINATIONS FOR WELDING TO CONSTITUTE THE IRON STATOR CORES OF DYNAMO-ELECTRIC MACHINES. THE MACHINE COMPRISES A CAGE INTO WHICH THE LAMINATIONS CAN BE INSERTED INDIVIDUALLY ONE UPON ANOTHER TO FORM A STACK, THE CAGE HAVING A HYDRAULIC PRESS AT ONE END FOR COMPRESSING THE STACK. THE CAGE IS MOUNTED FOR ROTATION ABOUT THE AXIS OF THE STACK IN A CRADLE WHICH IS ITSELF PIVOTED FOR ROTATION ABOUT A HORIZONTAL AXIS TRANSVERSE THE PIVOT AXIS OF THE CAGE, SO THAT AFTER A STACK OF LAMINATIONS HAS BEEN INSERTED INTO THE CAGE WITH ITS AXIS VERTICAL AND HAS BEEN COMPRESSED BY THE HYDRAULIC PRESS, THE CAGE CAN BE SWUNG DOWN TO A HORIZONTAL ORIENTATION WITH THE STACK STILL COMPRESSED IN IT BY THE PRESS, TO FACILITATE THE WELDING OF THE EDGES OF THE LAMINATIONS TOGETHER. LOCKING MEANS IS PROVIDED FOR LOCKING THE CAGE IN A NUMBER OF PREDETERMINED ANGULAR POSITIONS CONVENIENT FOR PERFORMING THE WELDING OPERATION.
