另外，本发明还公开了一种磁悬浮电机轴的护套工装，该护套工装用于将所述磁钢护套压紧至电机轴外壁；该护套工装包括护套孔和压紧面，护套孔用于被前主轴外端穿过，压紧面用于与磁钢护套上端面相接触。
另外，本发明还公开了一种磁悬浮电机转子组装方法，该方法用于组装所述一种磁悬浮电机转子，该方法包括以下的步骤：
（S1）组装隔磁环和磁钢：将两块隔磁环和三块磁钢端面用酒精擦拭干净，等酒精挥发后，将三块磁钢的两个端面和两块隔磁环的内侧端面都涂抹上设定量的金属粘合剂；涂抹完成后，按照安装顺序依次将隔磁环和磁钢紧靠的摆放在定位凹槽内；而后转动拧紧螺钉进而带动压紧块前移将隔磁环和磁钢组合件压紧，静置，等待金属粘合剂生效；
（S2）组装前主轴和后主轴：将前主轴内侧面和后主轴内侧面分别用酒精擦拭干净，隔磁环和磁钢组合件两端涂抹上金属粘合剂；将后主轴竖直放置在工作台上，隔磁环和磁钢组合件放置在后主轴的内侧面上，并且隔磁环和磁钢组合件下端面与后主轴内侧面相贴合；将两个定位块相对套设在后主轴外壁，并且定位面在轴向一端与后主轴外表面相贴合，另一端与隔磁环和磁钢组合件的外表面相贴合，而后用多个卡箍将两个定位块锁紧；使用相同操作将前主轴安装到隔磁环和磁钢组合件上端面，静置，等金属粘合剂生效；
（S3）切削电机轴：拆卸掉定位块和卡箍，将上步粘接形成的电机轴加工出定位台阶和上定位面；
（S4）组装磁钢护套：将磁钢护套热套至电机轴外壁，此时磁钢护套下端面与定位台阶一端面相贴合，磁钢护套上端面高于上定位面；将护套工装套设在前主轴外壁，护套工装的压紧面与磁钢护套上端面相贴合，并用液压机压住护套工装上端面；电机轴及磁钢护套组件冷却后，拆卸掉护套工装，并且将磁钢护套上端面切削至与上定位面平齐；

作为优选，隔磁环和磁钢紧靠的摆放在定位凹槽内后，将每个隔磁环和磁钢旋转360°；隔磁环和磁钢组合件竖直放置在后主轴的内侧面上以后，将隔磁环和磁钢组合件旋转360°；将前主轴竖直放置到隔磁环和磁钢组合件上以后，将前主轴旋转360°。
 有益效果
本发明采用上述技术方案的一种磁悬浮电机轴的定位工装、电机转子及组装方法的优点是：
定位块靠近贴合前主轴或者后主轴外表面时，考虑到制造误差等原因，定位块的一个定位凸起先与前主轴或者后主轴外表面相贴合；由于只有一个定位凸起贴合，定位块不具有稳定性，因此随着卡箍锁紧定位块时定位块的另一个定位凸起也与前主轴或者后主轴外表面靠近贴合并且具有稳定性；即两个定位凸起都能与前主轴或者后主轴外表面相贴合对其进行定位；当多个定位块同时被卡箍锁紧后，每个定位块的两个定位凸起都具有定位作用；从而增加了定位工装的定位部分，提高了电机轴组装时的定位精度。

 本发明的最佳实施方式
如图1、图2所示的一种磁悬浮电机轴的定位工装，该工装包括多个定位块81和卡箍82；定位块81包括定位块本体83和定位凸起84，定位块本体83为圆弧形状，两个定位凸起84位于定位块本体83的圆弧内侧；定位凸起84设置有定位面85，并且两个定位凸起84的定位面85的内接圆直径与磁钢的直径相同；定位面85在轴向一端用于与前主轴或者后主轴外表面相贴合，另一端用于与磁钢或者隔磁环外表面相贴合；多个定位块81沿着圆周方向分布，卡箍82套设在多个定位块81外侧表面，并且用于将多个定位块81卡紧。此种方式中，定位块81靠近贴合前主轴或者后主轴外表面时，考虑到制造误差等原因，定位块81的一个定位凸起84先与前主轴或者后主轴外表面相贴合；由于只有一个定位凸起84贴合，定位块81不具有稳定性，因此随着卡箍82锁紧定位块81时定位块81的另一个定位凸起84也与前主轴或者后主轴外表面靠近贴合并且具有稳定性；即两个定位凸起84都能与前主轴或者后主轴外表面相贴合对其进行定位；当多个定位块81同时被卡箍82锁紧后，每个定位块81的两个定位凸起84都具有定位作用；从而增加了定位工装的定位部分，提高了电机轴组装时的定位精度。
定位凸起84为沿着定位块本体83轴向分布的直线形状。定位面85为圆弧面或者平面。两个定位凸起84之间在圆周方向的圆弧夹角为45°，并且两个定位凸起84沿着定位块81圆弧中心对称分布。
如图1、图3所示，一种磁悬浮电机轴，该电机轴采用所述的磁悬浮电机轴的定位工装进行定位；该电机轴包括磁钢1、隔磁环2、前主轴3和后主轴4；多个磁钢1沿着轴向堆叠分布，并且相邻两个磁钢1之间通过胶水固定连接；两个隔磁环2分别位于堆叠磁钢1的两侧并且分别与最外侧磁钢1通过胶水固定连接；前主轴3的内侧端面和后主轴4的内侧端面分别通过胶水与两个隔磁环2外端面相连接。
如图4所示，一种磁悬浮电机轴的磁钢组装工装，该工装用于组装所述磁悬浮电机轴的磁钢1；该工装包括磁钢底座5、拧紧螺钉6和压紧块7；磁钢底座5设置有定位凹槽51、定位侧面52和螺钉孔，定位凹槽51为V型凹槽，V型凹槽两侧面分别与多个磁钢1和多个隔磁环2外表面相接触；定位侧面52与其中一个隔磁环2的外端面相贴合；拧紧螺钉6一端穿过螺钉孔并且与相螺钉孔旋合，压紧块7固定设置在拧紧螺钉6一端，压紧块7外端面与另一个隔磁环2的外端面相贴合。在组装磁钢时：将两块隔磁环2和三块磁钢1端面用酒精擦拭干净，等酒精挥发后，将三块磁钢1的两个端面和两块隔磁环2的内侧端面都涂抹上设定量的金属粘合剂；涂抹完成后，按照安装顺序依次将隔磁环2和磁钢1紧靠的摆放在定位凹槽51内；而后转动拧紧螺钉6进而带动压紧块7前移将隔磁环2和磁钢1组合件压紧，静置，等待金属粘合剂生效完成磁钢组装过程。而此种方式中，采用V型凹槽同时对隔磁环2和磁钢1进行定位，进而保证隔磁环2和磁钢1粘接后的同心度。
如图5所示，一种磁悬浮电机转子，该转子包括电机轴，电机轴上固定套设有磁钢护套41、前热套组件42、推力盘43和后热套组件44；电机轴设置有定位台阶45和上定位面46，磁钢护套41一端面与定位台阶45一端面相贴合，磁钢护套41另一端面与上定位面46相平齐；前热套组件42端面与上定位面46相贴合；推力盘43一端面与定位台阶45另一端面相贴合，推力盘43另一端面与后热套组件44端面相贴合。
如图6、图7所示，一种磁悬浮电机轴的护套工装，该护套工装用于将所述磁钢护套41压紧至电机轴外壁；该护套工装包括护套孔47和压紧面48，护套孔47用于被前主轴3外端穿过，压紧面48用于与磁钢护套41上端面相接触。磁钢护套41热套至电机轴外壁后，此时磁钢护套41下端面与定位台阶45一端面相贴合，磁钢护套41上端面高于上定位面46；将护套工装套设在前主轴3外壁，护套工装的压紧面48与磁钢护套41上端面相贴合，并用液压机压住护套工装上端面；电机轴及磁钢护套41组件冷却后，拆卸掉护套工装，并且将磁钢护套41上端面切削至与上定位面46平齐。此种方式中，热套后的磁钢护套41上端面被护套工装下压，防止磁钢护套41冷却过程中由于冷却收缩其下端面与定位台阶45贴合部位产生缝隙，保证磁钢护套41的装配精度。
另外，本发明还公开了一种磁悬浮电机转子组装方法，该方法用于组装所述一种磁悬浮电机转子，该方法包括以下的步骤：
（S1）组装隔磁环和磁钢：将两块隔磁环2和三块磁钢1端面用酒精擦拭干净，等酒精挥发后，将三块磁钢1的两个端面和两块隔磁环2的内侧端面都涂抹上设定量的金属粘合剂；涂抹完成后，按照安装顺序依次将隔磁环2和磁钢1紧靠的摆放在定位凹槽51内；而后转动拧紧螺钉6进而带动压紧块7前移将隔磁环2和磁钢1组合件压紧，静置，等待金属粘合剂生效；
（S2）组装前主轴和后主轴：将前主轴3内侧面和后主轴4内侧面分别用酒精擦拭干净，隔磁环2和磁钢1组合件两端涂抹上金属粘合剂；将后主轴4竖直放置在工作台上，隔磁环2和磁钢1组合件放置在后主轴4的内侧面上，并且隔磁环2和磁钢1组合件下端面与后主轴4内侧面相贴合；将两个定位块81相对套设在后主轴4外壁，并且定位面85在轴向一端与后主轴4外表面相贴合，另一端与隔磁环2和磁钢1组合件的外表面相贴合，而后用多个卡箍82将两个定位块81锁紧；使用相同操作将前主轴3安装到隔磁环2和磁钢1组合件上端面，静置，等金属粘合剂生效；此种方式中，采用竖直组装的方式将隔磁环2和磁钢1组合件组装至后主轴4上方，将前主轴3组装至隔磁环2和磁钢1组合件上方，而后对其在水平方向进行同轴定位；而隔磁环2和磁钢1组合件和前主轴3在竖直方向上分别受到下方的后主轴4及隔磁环2和磁钢1组合件的支撑以克服自身重力，不需要额外的支撑装置；从而避免了水平组装时需要其他装置支撑以克服重力的情况，减少了工装中定位装置的数量；同时，隔磁环2和磁钢1组合件和前主轴3在竖直方向被支撑后，其在水平方向进行同轴定位时只需要克服其与下方零件的较小的摩擦力就可以调节其位置；从而避免了水平组装时需要克服其自身重力才能竖直移动零件以调节位置的情况，减轻了工人的劳动强度。
（S3）切削电机轴：拆卸掉定位块81和卡箍82，将上步粘接形成的电机轴加工出定位台阶45和上定位面46；
（S4）组装磁钢护套：将磁钢护套41热套至电机轴外壁，此时磁钢护套41下端面与定位台阶45一端面相贴合，磁钢护套41上端面高于上定位面46；将护套工装套设在前主轴3外壁，护套工装的压紧面48与磁钢护套41上端面相贴合，并用液压机压住护套工装上端面；电机轴及磁钢护套41组件冷却后，拆卸掉护套工装，并且将磁钢护套41上端面切削至与上定位面46平齐；
（S5）热套电机转子剩余零件并切削至最终尺寸：将前热套组件42、推力盘43和后热套组件44分别热套至电机轴外壁后对其进行切削加工使其达到最终设计尺寸，而后对需要充磁的零件进行充磁完成磁悬浮电机转子的加工过程。
隔磁环2和磁钢1紧靠的摆放在定位凹槽51内后，将每个隔磁环2和磁钢1旋转360°；隔磁环2和磁钢1组合件竖直放置在后主轴4的内侧面上以后，将隔磁环2和磁钢1组合件旋转360°；将前主轴3竖直放置到隔磁环2和磁钢1组合件上以后，将前主轴3旋转360°。将相应零件旋转360°时可以将各零件间的气泡赶出，同时使金属粘合剂更加均匀，保证粘接强度。
