Description

Technical Field

[0001] The utility model relates to the technical field related to motor assembly, in particular to a motor magnetic ring assembly structure. Background Art

[0002] In the field of automotive parts assembly, micro motors and magnetic rings need to be assembled together. Magnetic rings are used to detect motor speed. Existing magnetic ring assembly equipment usually adopts one-time press-fitting, even if the positioning and auxiliary holding mechanisms are pre-assembled; because the magnetic ring may contact the positioning mechanism during the clamping and transfer process, resulting in positioning deviation, the magnetic ring is prone to incorrect press-fitting position after press-fitting, which leads to a temporary increase in the defective rate, seriously affecting product quality and is not easy to know. Therefore, the production of defective products caused by the above mechanical reasons should be reduced, and problems should be discovered in time.

[0003] The Chinese patent publication number is CN219420512U, and the authorization announcement date is July 25, 2023.

Therefore, the magnetic ring assembly has two steps of pre-installation and formal pressing, and during the formal pressing, there is a straightening component for auxiliary retention. Thereby, the assembly of the magnetic ring is more accurate and the product qualification rate is improved. The shortcoming of this utility model is that it is difficult to detect problems with the auxiliary mechanism, which easily leads to a certain amount of defective products. Utility Model Content
