考虑到转子冲片的各插孔有不同的安装角度和安装极性要求，本发明将这些插孔定义为定向插孔。
按照转子冲片的插孔布局图案，一些定向插孔关于转子冲片的中心旋转对称，本发明按照中心旋转对称的原则对转子冲片上的定向插孔进行分组。即在同一组定向插孔中，这些定向插孔在按照转子冲片的中心旋转一个角度后，其安装角度能够重合同时安装极性也相同。
本磁钢自动装配装置包括回转台和压磁钢机构，围绕回转台均布有多个工位，将转子冲片的定向插孔划分为多组，其中，每组定向插孔对应设置一个磁钢装配工位，每个磁钢装配工位均设有压磁钢机构，转子冲片随回转台回转一周时完成所有定向插孔的磁钢片压装。

铁芯旋转基座12和回转支撑26连接在一起安装到下滑台16上，气缸2通过气缸接头3与下滑台16连接在一起，气缸2固定在支架15上。
铁芯旋转基座12由伺服电机28驱动，实现转动和分度。
转子铁芯定位盘10通过铁芯旋转基座12抬起而脱离回转圆盘8，如图6所示，转子铁芯定位盘10和铁芯旋转基座12之间靠圆柱销14以及菱形销13来定位。

如图8所示，磁钢压装座19的侧面设有塑料隔片出孔19a，当塑料隔片推送至磁钢压装座19时，由推料机构29将塑料隔片从塑料隔片出孔中推出。
回转圆盘8转动到位，气缸2推动下滑台16抬起，安装于下滑台16上的铁芯旋转基座12抬起转子铁芯定位盘10，执行器1带动上滑台17降到压装位置，压头将磁钢5中的一磁钢片压入转子冲片25内，铁芯旋转基座12带动转子铁芯定位盘10旋转一个角度，压头再次将磁钢5中的一磁钢片压入转子冲片25内。
在本实施例中，磁钢装配工位用于选定转子冲片的定向插孔，不同磁钢装配工位可选择不同组的定向插孔，铁芯旋转基座能够分度转动，带动转子冲片的同一组定向插孔依次转动至磁钢片压装机构的压装位置，在一个磁钢装配工位上，磁钢片压装机构能够实现一组定向插孔的磁钢片压装。
