A method for pressing the winding stator iron core of a long rod motor into the frame

Abstract

The invention discloses a method for pressing a winding stator iron core of a pole motor in a machine base. Specifically, a lower press mounting die assembly (5) is arranged on a push trolley (6); in a press mounting process, the winding stator iron core (3) is placed on the lower press mounting die assembly, then an upper press mounting die assembly (2) is placed on the winding stator iron core (3), a lead wire is pulled out of the kidney-shaped hole of the upper press mounting die assembly (2) and placed in the upper press mounting die assembly (2), the machine base (4) is sleeved on the press mounting die assemblies, and finally the push trolley provided with a tool and a workpiece is pushed below a single column vertical hydraulic machine (1) to be pressed and mounted. Due to the fact that in the press mounting process, an upper locating guide structure and a lower locating guide structure are adopted and the machine base is pressed towards the winding stator iron core, the breakdown rate generated in the process is zero, the assembling quality that the winding stator iron core of the pole motor is pressed in the machine base is greatly improved, therefore, the performance of the generated motor is made to be capable of meeting design requirements, meanwhile, production efficiency is improved, and the labor intensity of workers is reduced.

Description

Technical field [0001] The invention relates to the field of assembling a stator iron core with windings and a motor frame, in particular to a method for pressing a winding stator iron core of a long rod motor into the frame. Background technique [0002] The long pole motor currently in use is an excitation source for mud separation screens in the petroleum industry and dewatering screens in the mining industry. For example, the VLB outdoor flameproof vibration motor produced by Zhongxiang Xinyu Electromechanical Manufacturing Co., Ltd. is a flameproof vibration motor developed and produced by the company according to the domestic market demand (referred to as VLB motor or long pole motor in this manual). It uses a set of eccentric blocks at both ends of the rotor of an asynchronous motor to rotate to generate centrifugal force, thereby forming a vibration source of exciting force. It can be used alone or in combination, with different installation methods to meet different pro...

Problems solved by technology

[0003] However, because the base of the VLB motor is much longer than the base of the ordinary vibration motor, after the stator core with windings is pressed into the base by the conventional press-fitting method, there will be more breakdowns between turns of the coil, and the scrap rate will be higher, and It is inconvenient to pass the lead wires through the hole of the outlet box of the machine base, and the labor intensity of the workers is extremely high
