Tool for stator and rotor assembling of permanent magnetism motor

Abstract

The invention discloses a tool for stator and rotor assembling of a permanent magnetism motor. The tool comprises a pedestal, an elevating device and a stator feeding device, the pedestal is providedwith a pressure head, a middle shoe plate and a right shoe plate, the pressure head is provided with a threaded tip, the middle and right shoe plates are provided with a long tip, the rotor is arranged between the threaded tip and the long tip, the stator is arranged on the long tip, and connected with the elevating device to ensure that the stator and rotor are arranged coaxially, and a stator feeding device is arranged under the elevating device and used to feed the stator to realize stator and rotor assembling. Stator and rotor are prevented from collision effectively, the disability rate of parts is reduced, the assembling quality is improved, and high economic benefit is generated; the assembling efficiency is improved, stator and rotor assembling can be completed by one person instead of at least two people traditionally, and the assembling safety is improved; and the permanent magnetism motor is assembled in a horizontal way, and the difficulty of manual operation is reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a tool for assembling a stator and rotor of a permanent magnet motor. Background technique [0002] At present, the permanent magnet motor manufacturers generally do not have special equipment or tools to assemble the permanent magnet motor stator and rotor. Generally, the stator and rotor assembly of small motors are assembled by hand, and the stator and rotor assembly of relatively large motors are carried out by using hoisting tools such as cranes and other auxiliary tools, which is time-consuming and laborious, with low labor efficiency and high risk. There are many problems in manual assembly: because the rotor has strong magnetism due to the permanent magnet, during the manual assembly process, affected by the magnetic pull, the rotor hits and absorbs the stator, thus causing damage to the rotor and stator; in addition, due to the influence of strong ma...

Problems solved by technology

Generally, the stator and rotor assembly of small motors are assembled by hand, and the stator and rotor assembly of relatively large motors are carried out by borrowing hoisting tools such as cranes and other auxiliary tools, which is time-consuming and laborious, with low labor efficiency and high risk.

There are many problems in manual assembly: because the rotor has strong magnetism due to the permanent magnet, during the manual assembly process, affected by the magnetic pull, the rotor hits and absorbs the stator, thus causing damage to the rotor and stator; in addition, due to the influence of strong magnetism, it is easy to cause the rotor The lack of concentricity with the stator assembly will cause failures such as bore sweeping; the assembly speed of manual assembly is uncontrollable, and it is easy to impact the bearing, causing damage to the bearing; due to the strong magnetic force generated by manual assembly, it is easy to pinch the assembler and cause potential safety hazards
