Description

有绕组定子铁芯槽盖纸压平工具
技术领域
本发明涉及中小型三相异步电动机有绕组定子铁芯的制造领域，特别适用于槽盖纸装配到有绕组定子铁芯的过程。
背景技术
电动机的有绕组定子铁芯(图6)一般包括定子铁芯和绕组，绕组手工嵌入定子铁芯中，定子铁芯的槽口用槽盖纸封住(图7)，槽盖纸应不凸出定子铁芯内圆表面。有绕组定子铁心端部经过整形达到图纸要求。在端部整形过程中，铁芯中的槽盖纸由于受力经常会凸出定子铁芯内圆表面。后续工作需要对突出的槽盖纸进行压平，以达到图纸要求。原来，操作者一般使用压纸板(图8)进行压平工作，每个槽都需要进行压平工作，操作繁琐、效率低下，而且压纸板经常对槽盖纸造成破坏，对产品质量造成影响。
发明内容
有绕组定子铁芯槽盖纸压平工具(图1)，包括压平头、手柄，其特征是：压平头的齿根圆直径Φ2(图2)等于定子铁芯内圆直径Φ(图6)减1mm，齿顶圆直径Φ1(图2)等于定子铁芯内径Φ(图2)加1.5mm，压平头的齿数等于定子槽数，压平头的齿宽B(图2)等于定子槽口宽B1(图7)减0.2～0.3mm，齿面均为圆弧过度，中心加工有M16的螺纹，压平头端部加工有5×30°倒角(图3)，具有导向保护作用；手柄(图4)一端滚花处理，另一端加工有一段M16的螺纹；压平头与手柄通过M16的螺纹装配在一起。
本发明的有益效果是：
在保证槽盖纸绝缘的前提下，对定子铁芯中所有的槽盖纸能一次性完成压平工作，提高了生产效率，保证了产品质量。
附图说明
图1是本发明装配示意图。
图2是本发明压平头主视图。
图3是本发明压平头左视图。
图4是本发明手柄主视图。
图5是本发明使用示意图。
图6是有绕组定子铁芯的结构示意图。
图7是图6中A-A剖面放大视图。
图8是压纸板结构示意图。
图9是图8中A向视图。
在图1～8中，零部件的名称：1——定子铁芯；2——绕组；3——槽盖纸。
具体实施方式
1.按图2压平头主视图和图3压平头左视图，加工本发明的压平头；按图4加工本发明的手柄；按图1本发明装配示意图，将压平头和手柄装配到位。
2.如图5本发明使用示意图所示，将压平头有倒角一端朝向有绕组定子铁芯(图6)，压平头的齿与有绕组定子铁芯的槽口对齐，借助手柄(图4)将压平头(图2)从有绕组定子铁芯(图6)的一端推到另一端，槽盖纸3(图7)在压平头(图2)的压力作用下，一次性完成了定子铁芯1(图7)所有的槽盖纸3(图7)的压平工作，达到了槽盖纸3(图7)包裹绕组2(图7)的绝缘作用。
