如图1至图6所示，本发明实施例提供的一种径向磁路组装装置，用于将上轴向磁片10和下轴向磁片20分别装配于多个瓦型磁铁30的上轴向侧面（图未示）和下轴向侧面（图未示），所述径向磁路组装装置包括磁性中心柱40以及套设于所述磁性中心柱40的下套环50和上套环60，所述磁性中心柱40包括顺序连接的大直径段41和小直径段42，所述大直径段41与小直径段42的连接处形成有用于供各所述瓦型磁铁30环形均布装配的限位台阶43，所述下套环50于所述大直径段41朝所述小直径段42的方向套入所述瓦型磁铁30外并用于限制各所述瓦型磁铁30径向位移，所述上套环60于所述小直径段42朝所述大直径段41的方向套入并将所述上轴向磁片10和所述下轴向磁片20分别压紧连接于各所述瓦型磁铁30的上轴向侧面和下轴向侧面。
具体地，本发明实施例的径向磁路组装装置，装配时，先将各个瓦型磁铁30环形均布于大直径段41与小直径段42的连接处形成的限位台阶43上，然后套入下套环50限制住各个瓦型磁铁30径向位移；或者，可以先将下套环50套入大直径段41外，再将各个瓦型磁铁30环形均布于限位台阶43与下套环50之间形成的空间内，如此通过下套环50实现对各个瓦型磁铁30径向位移的限制。接着再通过上套环60将上轴向磁片10压紧于各个瓦型磁铁30的上轴向侧面并使得各个瓦型磁铁30与上轴向磁片10固定连接，最后翻转上轴向磁片10，继续通过上套环60将下轴向磁片20压紧于各个瓦型磁铁30的下轴向侧面并使得各个瓦型磁铁30与下轴向磁片20固定连接，如此，在装配的过程中，即使各个瓦型磁铁30与上轴向磁片10和下轴向磁片20之间产生排斥的磁性力，但由于各个瓦型磁铁30在径向和轴向分别受到下套环50和上套环60的限制，从而可以有效降低加工难度，批量生产时，可以有效提高生产效率，进而可以节省大量的人力及组装成本。
结合图4所示，需要进一步说明的是，各个瓦型磁铁30在装配前，需要对其进行径向充磁，箭头所指即为各个瓦型磁铁30的磁场方向，将各个瓦型磁铁30装配到限位台阶43上时，各个瓦型磁铁30也会与小直径段42磁性吸附连接。
其中，磁性中心柱40优选采用软磁性材料制成，例如低碳钢。
本实施例中，所述下套环50的一端设有封板51，所述大直径段41的端部抵接于所述封板51的内侧。具体地，当将所述下套环50于所述大直径段41朝所述小直径段42的方向套入所述瓦型磁铁30外时，无需对下套环50的套入深度进行控制，直接推动下套环50直至下套环50的封板51的内侧与大直径段41的端部抵接，装配效率更高，且装配适量也可以得到保证。优选地，封板51与下套环50一体成型设计。
本实施例中，结合图6所示，所述径向磁路组装装置还包括用于将完成装配的所述上轴向磁片10与所述瓦型磁铁30以及完成装配的所述上轴向磁片10和所述下轴向磁片20与所述瓦型磁铁30从所述小直径段42上推出的套筒70。具体地，由于需要将上轴向磁片10和下轴向磁片20分别与环形均布的瓦型磁铁30的上轴向侧面和下轴向侧面装配连接，那么就需要在完成上轴向磁片10与各个瓦型磁铁30的上轴向侧面装配连接后，取出上轴向磁片10与各个瓦型磁铁30，此时，采用套筒70推动上轴向磁片10与各个瓦型磁铁30，直至上轴向磁片10与各个瓦型磁铁30脱出下直径段外，翻转上轴向磁片10，同时与上轴向磁片10连接的各个瓦型磁铁30也随着翻转，然后再将上轴向磁片10套入小直径段42外，直至上轴向磁片10抵接在限位台阶43，此时，再进行下轴向磁片20的装配，下轴向磁片20的装配与上轴向磁片10的装配方法一样，在此不再进行一一赘述。
优选地，上轴向磁片10和下轴向磁片20与各个瓦型磁铁30的装配连接可以采用于快干型胶水，例如A/B 胶或者厌氧胶。
本实施例中，所述下套环50为非金属下套环，所述上套环60为非金属上套环。具体地，下套环50和上套环60采用非金属材料制成可以避免与瓦型磁铁30、上轴向磁片10和下轴向磁片20之间产生相互吸附，从而可以确保对下套环50和上套环60的装拆自由，装配顺利进行。
本实施例中，具体地，所述非金属下套环为塑料下套环，所述非金属上套环为塑料上套环。塑料材质制成的下套环50和上套环60质量更轻，更容易制造，且成本更低。
优选地，所述磁性中心柱40为软磁性中心柱。
更优选地，所述软磁性中心柱为低碳钢中心柱。
本发明实施例还提供一种径向磁路组装方法，包括如下步骤：
S1：提供一磁性中心柱40，所述磁性中心柱40包括顺序连接的大直径段41和小直径段42，所述大直径段41与小直径段42的连接处形成有限位台阶43；
S2：提供一下套环50，先将多个瓦型磁铁30环形均布装配于所述限位台阶43上，再将所述下套环50于所述大直径段41朝所述小直径段42的方向套入所述瓦型磁铁30外并用于限制各所述瓦型磁铁30径向位移；或者，先将所述下套环50于所述大直径段41朝所述小直径段42的方向套入所述大直径段42外，再将各个所述瓦型磁铁30环形均布于所述限位台阶43与所述下套环50之间形成的空间内以使得所述下套环50限制各个所述瓦型磁铁30的径向位移；
S3：提供一上套环60，先将上轴向磁片10套入所述小直径段42外，再将所述上套环60于所述小直径段42朝所述大直径段41的方向套入并将所述上轴向磁片10压紧于各所述瓦型磁铁30的上轴向侧面以使所述上轴向磁片10与各所述瓦型磁铁30固定连接；
S4：将完成装配的所述上轴向磁片10与各所述瓦型磁铁30推出所述小直径段42外；
S5：先将完成装配的所述上轴向磁片10与各所述瓦型磁铁30翻转后套入所述小直径段42，接着将所述下轴向磁片20套入所述小直径段42外，再将所述上套环60于所述小直径段42朝所述大直径段41的方向套入并将所述下轴向磁片20压紧于各所述瓦型磁铁30的下轴向侧面以使所述下轴向磁片20与各所述瓦型磁铁30固定连接；；
S6：将完成装配的所述上轴向磁片10和所述上轴向磁片10与各所述瓦型磁铁30推出所述小直径段42外。

本实施例中，在所述步骤S3中，于各所述瓦型磁铁30的上轴向侧面上涂覆快干型胶水以使所述上轴向磁片10与各所述瓦型磁铁30固定连接；在所述步骤S5中，于各所述瓦型磁铁30的下轴向侧面上涂覆快干型胶水以使所述下轴向磁片20与各所述瓦型磁铁30固定连接。具体地，通过快干型胶水将上轴向磁片10和下轴向磁片20与各瓦型磁铁30固定连接，不但能够实现快速装配，且完成装配后的上轴向磁片10和下轴向磁片20与各瓦型磁铁30连接的稳定性极佳。
本实施例中，优选地，所述快干型胶水为A/B 胶或者厌氧胶。当然，在其他实施例中，快干型胶水还可以是黄胶或者白胶。
本实施例中，结合图6所示，在所述步骤S4中，提供一套筒70，通过所述套筒70将完成装配的所述上轴向磁片10与各所述瓦型磁铁30推出所述小直径段42外；在所述步骤S6中，通过所述套筒70将完成装配的所述上轴向磁片10和所述上轴向磁片10与各所述瓦型磁铁30推出所述小直径段42外。具体地，由于需要将上轴向磁片10和下轴向磁片20分别与环形均布的瓦型磁铁30的上轴向侧面和下轴向侧面装配连接，那么就需要在完成上轴向磁片10与各个瓦型磁铁30的上轴向侧面装配连接后，取出上轴向磁片10与各个瓦型磁铁30，此时，采用套筒70推动上轴向磁片10与各个瓦型磁铁30，直至上轴向磁片10与各个瓦型磁铁30脱出下直径段外，翻转上轴向磁片10，同时与上轴向磁片10连接的各个瓦型磁铁30也随着翻转，然后再将上轴向磁片10套入小直径段42外，直至上轴向磁片10抵接在限位台阶43，此时，再进行下轴向磁片20的装配，下轴向磁片20的装配与上轴向磁片10的装配方法一样，在此不再进行一一赘述。
本实施例中，所述下套环50的一端设有封板51，所述大直径段41的端部抵接于所述封板51的内侧。具体地，当将所述下套环50于所述大直径段41朝所述小直径段42的方向套入所述瓦型磁铁30外时，无需对下套环50的套入深度进行控制，直接推动下套环50直至下套环50的封板51的内侧与大直径段41的端部抵接，装配效率更高，且装配适量也可以得到保证。优选地，封板51与下套环50一体成型设计。
