Problems solved by technology

The magnetic poles are fixed on the stator shell by glue. At present, a chisel is used to separate the magnetic poles from the stator shell, which takes a long time. At the same time, some magnetic poles remain on the stator shell and need to be removed by grinding.

Embodiment 1

[0045] like Figure 4 As shown, this embodiment discloses a permanent magnet motor remanufacturing repair line with glued magnetic poles, including a heating device 7 , a rotating and fixing device 6 , a cooling pool 4 , a conveying device 5 , a knocking device 41 and an operating table 9 . The conveying device 5 is arranged obliquely in the cooling pool 4 , one end of the conveying device 5 is located in the cooling pool 4 , and one end extends out of the cooling pool 4 and is connected to one side of the operating platform 9 .

[0046] like Figure 7 As shown, the transmission device 5 includes a transmission motor 51, a transmission wheel 52 and a transmission belt 53, the transmission motor 51 and the transmission wheel 52 are arranged on both sides in the cooling pool 4, and the transmission belt 53 is installed on the transmission wheel 52 and the transmission motor 51. The conveyor belt 35 is evenly provided with several convex strips 54 , and the convex strips 54 can ...

Embodiment 2

[0062] The difference between this embodiment and the first embodiment is that: Step 1: After taking out the rotor in the stator casing 1; cleaning the magnetic poles 3 in the stator casing 1, and detecting and identifying whether each magnetic pole 3 is damaged. Before detecting and identifying the magnetic pole 3 in the stator shell 1, it is sandblasted and cleaned, and the visual inspection system detects the outer surface of the magnetic pole 3 after sand blasting to check whether there are cracks, depressions and other adverse conditions on the appearance of the magnetic pole 3 .

[0063] The damaged magnetic poles are marked and classified, and the stator shell is divided into several heating areas and cooling areas. The surface of the stator shell corresponding to the damaged magnetic poles is the heating area, and the surface of the stator shell corresponding to the undamaged magnetic poles is the cooling area. like Figure 5 As shown, put the stator housing 1 into th...

Abstract

The invention discloses a remanufacturing and repairing process and assembly line of a permanent magnet motor with glued magnetic poles, comprising the following steps: firstly, the end cover of the permanent magnet motor to be repaired is opened, and the outer surface of the stator shell is heated until the glue melts and fails, Beat the magnetic pole inside the stator casing to separate the magnetic pole from the stator casing; cool the stator casing after separation, and glue the side where the new magnetic pole is in contact with the stator casing; the positive and negative magnetic poles have been stained with glue alternately glued to the inner wall of the stator housing. The invention also discloses a permanent magnet motor remanufacturing and repairing assembly line with glued magnetic poles, which includes a rotating fixing device, a heating device, a cooling pool, a conveying device and an operating table. The invention can realize the complete detachment of the magnetic pole and the stator shell, prevent the magnetic pole from remaining in the stator shell, and at the same time not damage the stator shell, and realize the remanufacturing production of the permanent magnet motor.

Description

technical field [0001] The invention relates to the technical field of repairing a permanent magnet motor, in particular to a remanufacturing and repairing process and assembly line of a permanent magnet motor with glued magnetic poles. Background technique [0002] In the current remanufacturing process of permanent magnet motors, it is necessary to disassemble and replace the damaged and invalid magnetic poles of the permanent magnet motor. In the process of remanufacturing, the damaged and invalid magnetic poles need to be disassembled from the stator shell Replace the poles before reinstalling the stator housing. The magnetic poles are fixed on the stator housing by glue. At present, a chisel is used to separate the magnetic poles from the stator housing, which takes a long time. At the same time, some magnetic poles remain on the stator housing and need to be removed by grinding. Contents of the invention [0003] The purpose of the present invention is to provide a ...
