Auxiliary laminating device for segmental stator iron core

Abstract

The invention relates to an auxiliary laminating device for a segmental stator iron core. The auxiliary laminating device comprises a pressure plate, a screw rod assembly, outer circle positioning rods, an equi-index plate, a brace rod assembly and a baseplate, wherein the baseplate is used for holding a segmental stator iron core, the pressure plate is used for pressing the top of the segmental stator iron core, and the pressure plate is connected with the baseplate through the screw rod assembly for pressurizing the segmental stator iron core; equal division holes corresponding to the size of the outer diameter of stator segments and the number of pieces for splicing a full circle are formed in the baseplate, positioning semi-circular holes corresponding to the pieces for splicing the full circle in number are formed in an inner hole of the equi-index plate, the lower ends of the outer circle positioning rods are correspondingly assembled in the equal division holes in the baseplate, and the upper ends of the outer circle positioning rods are positioned by relying on the corresponding positioning semi-circular holes in the equi-index plate; and the equi-index plate is supported through the brace rod assembly and is positioned in height. The auxiliary laminating device for the segmental stator iron core, disclosed by the invention, is simple and novel in structure and good in actual using effects, and can greatly improve the lamination efficiency of the segmental stator iron core, and ensure the lamination quality of the segmental stator iron core.

Description

technical field [0001] The invention relates to an auxiliary device for assembling a segmented stator core, in particular to an auxiliary segmented stator core lamination device. Background technique [0002] The stator core structure of large AC motors is mostly fan-shaped stator core. The traditional lamination method is to use the inner circle of the stator segment to position the inner hole of the stator segment for lamination. Due to the machining accuracy of the table itself and the operator's lamination skills, etc. Influenced by various factors, it is difficult to meet the design requirements for the verticality, groove quality, and inner and outer diameters of the segmented stator core. It affects the overall performance of the motor to a certain extent, so it needs to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a simple and novel auxiliary segment stator cor...
