扁铜线电机能够大幅提升电机槽满率，继而提高电机的性能，因而，目前扁铜线应用于电机领域也越来越多，但若扁铜线的安装加工不能满足电机需求或者其加工工艺精度不高、加工难度高，也将会导致电机的生产效率降低，并且精度不高会致使电机后续使用的效率大打折扣，故而，对于扁铜线电机而言，扁铜线的安装加工的效果直接影响到电机的性能。
现有技术中，为了保护绝缘纸多采用人工插线，这样导致生产效率低，同时，手动插线的过程中，绝缘纸在定子槽内窜动，从而使绝缘纸端部不整齐。因此，我们需要开发一款能保护绝缘纸的插线装置，既能提高生产效率，又能满足装配精度要求。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
图1-图10示出了根据本发明的一些实施例。
如图1-4所示，一种扁线发卡插入定子的定位导向装置，包括安装底板1、前导向装置40、后定位装置50、以及固定支架，前导向装置40和后定位装置50安装在固定 支架上，且前导向装置40和后定位装置50通过连接柱8连接到一起，形成定子铁芯的定位结构，用于固定安装定子铁芯12。
其中，前导向装置40和后定位装置50均为多个滑动块沿圆径向进行同时伸缩的结构，通过驱动机构控制滑动块的伸缩。前导向装置40包括驱动机构、旋转板6、滑块板14、前挡盖16、滑动块一17、以及固定在滑动块一17上的导向动片13。
其中，驱动机构用于带动旋转板6在滑块板14前侧转动，旋转板6转动过程中带动滑动块一17在滑块板14内径向滑动，进而带动导向动片13移动到定子铁芯12的轴向一端，使导向动片13上的导向槽与定子铁芯12上的插槽对齐，由于导向动片13上具有导向槽，在扁线发卡插入定子铁芯过程中导向槽起到导向作用。
具体地，如图4～6所示，滑块板14、旋转板6、前挡盖16均为空心圆环状板件，三者按顺序依次连接设置并保持同轴，而且所述旋转板6能在滑块板14与前挡盖16之间旋转。
其中，所述滑块板14上开有若干个沿径向延伸的直槽，若干直槽在滑块板14上环形阵列分布，同时滑动块一17安装设置在滑块板14上的直槽内并能沿直槽滑动，所述旋转板6上开设有若干弧形轨道槽61，而滑动块一17上靠近旋转板6一侧的侧面固定安装有滑片销19，且滑片销19延伸至弧形轨道槽61内。
其中，弧形轨道槽61沿旋转板6的周向和径向组合的方向延伸，形成一个倾斜的弧形轨道，当驱动机构带动所述旋转板6转动时，弧形轨道槽61的位置随旋转板6发生改变，由于滑片销19受弧形轨道槽61限制，滑动块一17受滑块板14中直槽的限制，使滑片销19能带动所述滑动块一17在滑块板14中的直槽内移动，进而使滑动块一17前端的导向动片13朝定子铁芯的中心轴线方向移动，并移动到定子铁芯的轴向一端的前侧，实现导向功能。
其中，如图7～图9所示，所述导向动片13具有导向块和导向槽，导向槽前端具有倒角一，导向块前端具有倒角二，其中，定子铁芯插槽的内表面设置有绝缘纸，绝缘纸的周向宽度L1略大于导向槽的宽度L2，同时导向槽的宽度L2大于扁线发卡的宽度L3。
在扁线发卡80沿轴线插入定子铁芯插槽过程中，扁线发卡先经过导向动片13，所述导向槽131对扁线发卡80进行周向限位，所述导向块132对扁线发卡80进行径向限位，由于导向槽的宽度L2小于绝缘纸的周向宽度L1，使得扁线发卡插装过程中不会直接压在绝缘纸的前端，避免插线过程中损伤绝缘纸121。
具体地，后定位装置50的结构与前导向装置40相似，后定位装置50包括与前导向装置一样的结构旋转板6、滑块板14、前挡盖16，还包括与滑动块一17类似的滑 动块二20，其中，后定位装置50的滑动块二20前端没有安装导向动片13，不能对扁线发卡80进行导向。
其中，如图10所示，滑动块二20前端具有开口槽一201和开口槽二202，开口槽一201的略大于绝缘纸121的尺寸，所述绝缘纸121的周向宽度小于所述开口槽一201的宽度并大于所述开口槽二202的宽度，且所述开口槽二202的宽度大于所述扁线发卡80的宽度，由于开口槽一201的宽度与开口槽二202的宽度不等，形成了挡肩203，在插线过程中，绝缘纸121末端位于开口槽一201内，挡肩203能阻止绝缘纸121沿轴向移动，从而使滑动块二20能在保护绝缘纸轴向移动的同时不影响扁线通过。
在一实施例中，如图3所示，在前导向装置40上固定有定位盘10，在后定位装置50上固定有定位圆弧11，定位盘10和定位圆弧11形成中心定位，定位盘10和后导向装置伸出后的滑动块轴向定位，用于定子铁芯12的轴向定位和中心定位，此处做成分体的原因为方便修配和调整。此外，在安装底板1上安装右止转键9，右止转键9与定子铁芯上的定位槽相配合，以防止定子铁芯发生周向旋转。
在一实施例中，如图1、4所示，驱动机构包括气缸4、连接板15、气缸固定板5、以及接头18，所述气缸4下端通过气缸固定板5与固定支架中的安装底板1铰接，所述气缸4上端固定设置有接头18，其中，连接板15与旋转板6周向一侧连接，且连接板15与接头18铰接，从而能将气缸4的直线运动转化为旋转板6的转动。
在一实施例中，如图1和图3所示，固定支架包括安装底板1、左立柱2、右立柱3、以及两个U型支架7，左立柱2、右立柱3沿竖直方向安装在所述安装底板1左右两侧，两个U型支架7安装在左立柱2与右立柱3之间，并分别与两者固定连接，前导向装置40、后定位装置50分别固定安装在U型支架7内，通过固定支架实现前导向装置40、后定位装置50的安装固定。
在一实施例中，如图1和图3所示，前导向装置40和后定位装置50通过上下左右四个连接柱8连接到一起，以保证前导向装置与后定位装置中心重合。
本发明的扁线发卡插入定子的定位导向装置的工作过程如下：
首先，通过气缸4控制旋转板6转动，使前导向装置40中的滑动块一17和后定位装置50中的滑动块二20均处于向外缩回状态，然后，人工或者自动化设备将定子铁芯12由后定位装置50推入定位工装中，并通过前导向装置40上的定位盘10和后定位装置50上的定位圆弧11、以及右止转键9对定子铁芯12进行固定。
然后，通过气缸4控制旋转板6转动，使前导向装置40中的滑动块一17和后定位装置50中的滑动块二20均向内伸出。
待扁线发卡准备好后，扁线发卡由前导向装置40侧进行人工或机械插入。
在扁线发卡插装过程中，通过滑动块一17进行导向使扁线的前端进入到定子铁芯12的槽口中，其中，扁线发卡移动时先经过导向动片13，导向槽131对扁线发卡80进行周向限位，导向块132对扁线发卡80进行径向限位，由于导向槽的宽度L2小于绝缘纸的周向L1，在定子径向和周向上能对扁线发卡径向准确定位，避免扁线发卡插装过程中直接压到绝缘纸端部，避免插线过程中损伤绝缘纸121。
待扁线发卡的前端全部插入定子铁芯12的槽口中后，通过气缸4控制旋转板6转动，使前导向装置40中的滑动块一17缩回，扁线发卡80再继续插装到位。
在扁线发卡插装过程中，后定位装置50中的滑动块二20处于伸出状态，使绝缘纸121末端位于开口槽一201内，挡肩203用于阻止绝缘纸121沿轴向移动，防止绝缘纸121在轴向上的窜动。
插装完成后，通过气缸4控制旋转板6转动，使后定位装置50中的滑动块二20处于向外缩回状态，再通过人工或自动化设备取出定子铁芯，工作完成。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
