Motor rotor fixing tool, fixing system and fixing method

Abstract

The invention discloses a motor rotor fixing tool, a fixing system and a fixing method, and belongs to the field of motor production. The motor rotor fixing tool comprises a base and a sealing cover, the top end of the base is provided with a bottom end rotating shaft containing hole and a bottom end lamination containing hole, the bottom end of the sealing cover is provided with a top end rotating shaft containing hole and a top end lamination containing hole, and when the base is connected with the sealing cover, a relatively closed rotor containing cavity is formed. The connecting surface of the base and the sealing cover is vertically matched with the central axis of the accommodating cavity of the rotor, the bottom end rotating shaft accommodating hole, the bottom end lamination accommodating hole, the top end rotating shaft accommodating hole and the top end lamination accommodating hole are matched with the rotor in shape, and the end parts of the bottom end lamination accommodating hole and the top end lamination accommodating hole are propped against a magnet yoke lamination of the rotor and apply pre-tightening force to the magnet yoke lamination. The problem that the rotating shaft is bent due to the fact that the magnet yoke lamination is suspended at a single angle in an existing fixing tool is solved, and the problems that the rotating shaft is scratched and the magnet yoke lamination is damaged due to impact are solved.

Description

technical field [0001] The invention belongs to the field of motor production, in particular to a motor rotor fixing tool, a fixing system and a fixing method. Background technique [0002] The production and manufacturing of existing motors is to transport all parts and components to the assembly workshop after they are manufactured in different workshops or even different factory companies. Although this production method can give full play to the strengths of different manufacturing companies, the transportation of the motor rotor It is to place the rotating shaft of the rotor horizontally in the box. In order to facilitate the use of the rotor, the yoke laminations will be suspended in the air to reserve space for the hands to take out.

[0002] The production and manufacturing of existing motors is to transport all parts and components to the assembly workshop after they are manufactured in different workshops or even different factory companies. Although this production method can give full play to the strengths of different manufacturing companies, the transportation of the motor rotor It is to place the rotating shaft of the rotor horizontally in the box. In order to facilitate the use of the rotor, the yoke laminations will be suspended in the air to reserve space for the hands to take out. However, the yoke laminations are the heaviest part of the rotor. When the storage time is over For a long time, the yoke laminations suspended at a single angle have the problem of shaft bending, and improper storage and transportation will cause the rotor to be placed vertically, especially during transportation. The rotor will move in the box, and there will be shaft scratches and The yoke laminations are damaged by impact, so it is necessary to provide a fixed tool that can support the yoke laminations and prevent the rotor from moving in the box
