Description

一种换向器排片装置 技术领域
本发明属于换向器排片领域，特别涉及一种换向器排片装置。
背景技术
换向器是直流电机和交流整流子电动机电枢的一个重要部件，在电机转动时起换向作用。换向器由若干片换向片和换向器基座制成，而换向器的基座一般采用电木粉高温压制而成，同时为了将换向片嵌入在换向器基座内，就必须先对换向片进行排片，然后排列好的换向片才能进行下一道的压注工序。
目前，由于排片模芯的设计和工艺的限制，排片后的换向片在塑料套上的轴向位置会参差不齐，容易出现不合格，且排片后换向片容易缺失和脱落，且由于云母片比较薄，使得云母片在插入换向片本体之间时容易出现偏斜，使得换向片的本体也出现偏斜，从而影响换向器成品的质量。
发明内容
发明目的：为了克服以上不足，本发明的目的是提供一种换向器排片装置，其结构简单，易于实现，并能准确的定位换向片和云母片的位置，提高了安装精度，提高了产品性能稳定性，提升了生产效率。

进一步的，上述的换向器排片装置，所述凹槽与凸部沿模芯外侧圆周均匀排布。
进一步的，上述的换向器排片装置，所述凹槽为瓶形，所述凸部为T型。
进一步的，上述的换向器排片装置，所述凹槽瓶口与瓶身转角处设有圆角。所述圆角有利于换向片的安装和模芯的成型。

进一步的，上述的换向器排片装置，所述模芯的高度不小于限位轴的高度。
进一步的，上述的换向器排片装置，所述限位盘的外径大于换向片围成的外径。
