一种定子冲片叠压工装
本技术涉及永磁无刷电机制造领域,尤其是一种定子冲片叠压工装。
技术介绍
为避免气隙磁导波的齿槽影响,稀土永磁无刷电机的定子铁芯的内孔壁上一般设置有内孔斜槽。该类型的定子铁芯由若干片定子冲片层层叠压而成,对应的每定子冲片的内孔内均设置有斜槽,各片定子冲片内的斜槽依次连接即形成定子铁芯内的内孔斜槽。如何保证堆叠完成的定子铁芯内的内孔斜槽与预定结构一致一直是困扰本行业的一个难题。
技术实现思路
为了解决现有技术中的上述技术问题,本技术提出了一种定子冲片叠压工装,其能够实现对定子冲片的叠压装配,以获得具有预定形状的内孔斜槽的定子铁芯。一种定子冲片叠压工装,其用于实现对定子冲片的叠压,以获得内孔内具有预定形状的斜槽的定子铁芯,其特征在于,其包括下压板、上压板、内柱及压紧螺杆,其中:所述下压板的周缘处沿周向设置有若干下压紧孔,所述下压紧孔的内壁上形成有内螺纹;所述上压板的周缘处沿周向设置有若干与所述若干下压紧孔一一对应的上压紧孔;所述内柱设置在所述下压板和所述上压板之间,所述内柱的外侧壁上形成有凸起的导向条,所述内柱用于套装待叠压的定子冲片,所述导向条的形状与所述预定形状的斜槽相匹配;所述压紧螺杆与所述下压紧孔及所述上压紧孔对应设置,其从所述上压紧孔穿入并从对应的所述下压紧孔穿出,所述压紧螺杆的一端设有与所述下压紧孔内的内螺纹相匹配的外螺纹,所述压紧螺杆的另一端设有螺帽。进一步的,其还包括下定位板和上定位板,其中:所述下定位板与所述下压板贴合, ...
