Description

Technical Field

[0001] The utility model relates to the technical field of crimping, in particular to a stator concentric crimping device for controlling tooth separation. Background Art

[0002] At present, the stator structure of the traditional small-power (0.2kw-1kw) 60 / 80 frame servo motor is generally an integral stator punching. However, due to the high difficulty of the integral stator punching off the production line and the limitations of performance, a better performance solution is being gradually replaced, from the original integral type to a 12-petal sun tooth, that is, a tooth-tooth separation structure. The most difficult technical difficulty in the splicing link is how to ensure the concentricity of the crimping of the stator punching of the tooth part and the stator punching of the internal tooth part to ensure the consistency of the product. The splicing method used in the prior art is mostly a core rod plus a throat clamp locking method. Due to the uneven force at the locking point of the throat clamp, the concentricity and ovality of the locked stator punching are too different, resulting in a high defective rate in the production process, and it is impossible to meet the technical requirements of the product. At the same time, due to the locking force, the welds between the stator punchings are larger, and they are easy to tilt during the crimping process, resulting in poor product quality and consistency.
