Problems solved by technology

For the assembly sequence of the pole box, the pole box can be assembled on the rotor first, and then the final assembly of the stator and rotor is carried out. The advantage of this assembly is that the pole box can be positioned on the rotor when it is assembled on the rotor, and the installation is convenient. The disadvantage is When the stator and rotor are assembled, the rotor has strong magnetism, which is very difficult for large motors
Another pole box assembly method is to first assemble the pole boxes into a string, then assemble the stator and rotor, and finally assemble the string of pole boxes to the rotor. However, due to the large size of the permanent magnet of a large motor, the magnetic pole The repulsion between the boxes is very strong, and the magnetic pole boxes must be operated with special tooling equipment when they are installed in series

Abstract

The invention relates to the technical field of assembling process, in particular to a large-scale motor rotor string magnetic pole box assembling tool and assembling method. The assembling tool comprises a tool base, an oil cylinder mounting plate, a pushing plate, a pressing tool and a pressing plate. The tool base comprises a bottom plate, side plates and an end plate. The bottom plate, the side plates and the end plate are all detachably connected. The side plates are symmetrically installed on the left and right sides of the bottom plate and the end plate and are perpendicular to the endplate. The inner side of the side plates is provided with a plurality of longitudinal strip grooves. The spacing of the two adjacent longitudinal strip grooves is the same. The oil cylinder mounting plate can be inserted into the tool base along the symmetrically arranged longitudinal strip grooves. The outer side of the side plate sis provided with a transverse chute. The pressing tool can slidealong the symmetrically arranged transverse chutes. The structure is compact, the design of split bolt connection is applied to the tool base, the processing of parts is economical and good, and one or more of the bottom plate, the side plates or the end plate can be replaced to adapt to the assembling of the string magnetic pole box of various specifications.

Description

technical field [0001] The invention relates to the technical field of assembly technology, in particular to a large-scale motor rotor series magnetic pole box assembly tool and assembly method. Background technique [0002] According to the assembly position of permanent magnets, permanent magnet synchronous motors can be mainly divided into surface mount type and built-in type. In the surface-mounted permanent magnet synchronous motor, the permanent magnet is located on the outer surface of the rotor core. This kind of motor has a simple structure and is easy to install, but the anti-corrosion and anti-collision of the permanent magnet are difficult to deal with; while the permanent magnet of the built-in permanent magnet synchronous motor Located inside the rotor, there is a pole shoe made of ferromagnetic material between the outer surface of the permanent magnet and the inner circle of the stator core. The pole shoe protects the permanent magnet, making it anti-corrosio...
