Description

转子线圈整形装置 技术领域
本发明涉及一种电机转子组装设备，具体涉及一种转子线圈整形装置。
 背景技术
转子由转子铁芯、转子轴等部件构成，转子铁芯上绕线后需要在转子铁芯的转子槽内塞槽签，通过使槽签沿转子轴轴向的方向进行槽签的安装，转子两端的铜线会挡在转子槽的轴向侧，需要将转子两端的线圈向内侧压紧以露出转子槽，从而便于槽签的安装。现有技术中采用人工压线圈的方式进行线圈的整形，但效率较低，工人的劳动强度较高。
 技术问题
本发明的目的是提供一种能提高生产效率，且能降低工人劳动强度的转子线圈整形装置。
 技术解决方案
为实现上述目的，本发明采用如下技术方案：一种转子线圈整形装置，包括定位块及位于定位块上方的压块，所述定位块中部设有向上延伸并沿前后方向设置的定位凸起，所述定位凸起的宽度与转子的转子槽开口处宽度相同，所述定位块前后两端至少有一端具有向上延的限位凸起，所述压块下侧固定有上整形片，所述上整形片具有向下开口的弧形槽。
本发明装置使用时，将转子放置在定位块上，使定位凸起位于转子铁芯上的转子槽内，然后进行转子的轴向移动，以使转子铁芯轴向端面与限位凸起相贴，然后下压压块以使上整形刀片的弧形槽槽壁与线圈接触并压紧，然后进行转子的转动，以将转子圈周向面都压紧。其中，通过定位凸起以实现转子的径向限位。其中，通过限位凸起以使线圈与上整形刀片对准，以避免压块向下移动时上整形刀片与转子铁芯接触。
作为优选，所述定位块固定于定位座上，所述定位座套设在若干竖向设置的导向杆上，所述导向杆下端与底板固定，所述定位座与底板之间设有弹簧，所述弹簧套设在导向杆上，所述底板上设有向上延伸的下整形片，所述下整形片具有向上开口的弧形槽，下整形片位于一个上整形片正下方。上述设置以增加每次压块下压时被压紧整形线圈的面积，以提高效率。其中，定位块与定位座可以是一体的，也可以是两个相互独立的零部件。
作为优选，所述压块前后两端均设有上整形片，所述定位座前后两侧均设有下整形片，每个下整形片均位于一个上整形片正下方。上述设置以提高本发明装置使用时的稳定性，避免转子在线圈压紧整形时发生倾覆的情况发生。
作为优选，所述定位块可拆卸固定于定位座上。当转子为斜槽转子时，根据转子槽倾斜角度更换不同具有相对应倾斜角度定位凸起的定位座。
作为优选，所述定位座形成有向上开口的V形槽，V形槽包括两个倾斜设置以构成V形结构的支撑槽面，所述定位块固定于V形槽中部，以使定位块位于两个支撑槽面之间。支撑槽面用于对转子的转子铁芯进行支撑，以限制转子径向位移，提高本发明装置使用时的稳定性。
作为优选，所述压块固定于压机输出端，所述压块与导向块一端固定，所述导向块另一端位于固定板的导向槽内，所述导向槽竖向设置。导向块和导向槽用于压块的导向，避免压块带动上整形片的转动。
 有益效果
本发明具有能提高生产效率，且能降低工人劳动强度的优点。
