Magnetic pole assembly method and system

Abstract

The invention discloses a magnetic pole assembly method, which comprises the following steps of: inversely arranging a plurality of magnetic poles on a horizontally arranged magnetic pole tool one byone, so that mounting bosses of any magnetic pole are matched with supporting bosses of the magnetic pole tool in a one-to-one correspondence manner; powering on all the magnetic poles, so that any mounting boss is tightly attached to the corresponding supporting boss through magnetic attraction force, and all the magnetic poles are accurately positioned; and finally, aligning and matching the magnetic pole base with all magnetic poles, and fixedly connecting the magnetic poles with the magnetic pole base. Manual positioning can be carried out without the help of measuring tools such as a leveling instrument and a feeler gauge hand in the magnetic pole assembling process. The magnetic pole can be accurately and stably fixed to the supporting boss of the magnetic pole tool through magneticattraction force, the magnetic pole is prevented from being affected by natural bending deformation of the magnetic pole tool during positioning, the magnetic pole is prevented from moving relative tothe magnetic pole tool in the assembling process, it is guaranteed that the magnetic pole and the magnetic pole base are accurately aligned, assembling errors and accumulated errors are reduced, andthe assembling precision is high. The invention further discloses a magnetic pole assembly system.

Description

technical field [0001] The invention relates to the technical field of magnetic pole assembly, in particular to a magnetic pole assembly method. The invention also relates to a pole assembly system. Background technique [0002] Large-scale synchronous motors usually use the forward installation method to install many magnetic poles on the magnetic pole base. Specifically, each magnetic pole is first placed on the magnetic pole tooling one by one, so that the installation bosses of the magnetic poles are matched with the support bosses of the magnetic pole tooling one by one. Limit the horizontal position of each magnetic pole; then use a spirit level and feeler gauge to manually adjust the height difference between the magnetic poles, so that the magnetic poles are accurately inverted in the corresponding support bosses; finally, use the magnetic pole tooling to directly press each magnetic pole on the magnetic pole base It is convenient to accurately fix each magnetic pol...

Problems solved by technology

[0003] However, in view of the slight deflection and deformation of the magnetic pole tooling, it is difficult to ensure that the mounting boss and the supporting boss are in close contact, resulting in a certain degree of assembly error in the placement of each magnetic pole, and a large number of magnetic poles in the assembly process. It is easy to produce a large cumulative error in the process, which affects the assembly accuracy between the magnetic pole and the magnetic pole base; further, when the magnetic pole is manually assembled with the help of a level ruler and a feeler gauge, the assembly error and the cumulative error are further increased due to the limitation of the operating level
