Motor stator core laminating tool

Abstract

The name of the present invention is a lamination tooling for motor stator cores, and relates to a tooling used for lamination of motor stator cores. It is mainly to solve the problem that the existing motor stator core lamination tooling cannot meet the requirements of the core lamination coefficient and the unevenness of the groove shape after lamination. question. The present invention includes a pressure tire arranged in the center hole of the base and a pressure die disposed on the other end of the pressure tire, and is characterized in that the pressure tire is a cylindrical body provided with upper and lower pressure plates, and the pressure tire is arranged in the center of the cylindrical body along the axial direction A support column is provided, and the two ends of the support column are respectively fixed on the upper and lower pressure plates, and fixed ribs and movable ribs are arranged on the outer wall of the tire cylinder, and the two ends of the fixed ribs and the movable ribs are respectively fixed on the upper and lower pressure plates. The pressure tire of the present invention has the functions of positioning and tensioning, can ensure the irregularity of the groove shape after the iron core is laminated, and is convenient for hoisting and dismounting;

Description

technical field [0001] The invention relates to a motor stator core lamination tool, in particular to a locomotive generator stator core lamination tool. Background technique [0002] At present, the known lamination tooling for stator cores of electric motors has the following disadvantages: ①The core body of the lamination tooling is integral or wedge-shaped. If the gap between the lamination and the stator core punching is large, it cannot satisfy the lamination coefficient of the core and the groove after lamination. Stator core punches are easily deformed after lamination; if the fit gap with the punches is small, it will be difficult to take the mold after lamination, difficult to disassemble after use, and difficult to hoist. Usually, cold pressing or heating the stator core is required. The traditional method has high work intensity and poor safety; ②The original tooling failed to effectively control the problem of loosening of the teeth of the punching sheet. Cont...
