Abstract

本发明公开了换向器铜片，包括主片体和设于主片体内侧面的勾脚，其特征在于：勾脚沿主片体的高度方向上下设有偶数只，单数勾脚设有加强横条时双数勾脚不设加强横条，双数勾脚设有加强横条时单数勾脚不设加强横条，所有勾脚上均开设有条形孔，所述加强横条固定穿设在条形孔内；所述加强横条为弧形板结构。本发明具有偶数只勾脚且加强横条错开设置，有效增强换向器成型时与换向器基体之间的结合力，提高换向器产品的机械强度和超速性能。

Description

换向器铜片
技术领域：
本发明涉及换向器技术领域，具体涉及一种换向器铜片的改进发明。
背景技术：
换向器一般由换向器基体和在换向器基体的外圆作圆周排布的换向器铜片组成，换向器铜片的基本构造为：包括主片体和设于主片体内侧面的勾脚，在换向器成型时，主片体通过勾脚植入换向器基体内与换向器基体牢固结合在一起。现有技术的换向器铜片，受限于勾脚的结构设计，要进一步增强换向器成型时与换向器基体之间的结合力存在较大技术困难，换向器产品机械强度和超速性能不能得到更进一步的提高，因此不能很好满足电动工具越来越高的速度要求。
发明内容：
鉴于背景技术的不足，本发明的目的旨在提供一种具有偶数只勾脚且加强横条错开设置，有效增强换向器成型时与换向器基体之间的结合力，提高换向器产品机械强度和超速性能的换向器铜片。
本发明是采取如下技术方案来完成的：
换向器铜片，包括主片体和设于主片体内侧面的勾脚，其特征在于：勾脚沿主片体的高度方向上下设有偶数只，单数勾脚设有加强横条时双数勾脚不设加强横条，双数勾脚设有加强横条时单数勾脚不设加强横条，所有勾脚上均开设有条形孔，所述加强横条固定穿设在条形孔内。
所述加强横条为弧形板结构。
上述技术方案的换向器铜片，勾脚沿主片体的高度方向上下设有偶数只，加强横条在勾脚上错开设置，这样一来，首先，加强横条的横向设置可以极大增强提高与换向器基体的结合强度，而且由于加强横条的错开设置，加强横条的横向长度可以加长，更利于与换向器基体的结合强度的加强，因此能够有效增强换向器成型时与换向器基体之间的结合力，提高换向器产品的机械强度和超速性能。
附图说明：
本发明有如下附图：
图1为本发明的结构示意图，
图2为图1的俯视方向图。
具体实施方式：
如图所示，本发明的换向器铜片，包括主片体1和设于主片体1内侧面的勾脚2，勾脚2沿主片体1的高度方向上下设有偶数只的四只，单数勾脚设有加强横条3时双数勾脚不设加强横条(图1中所示)，当然，同样道理，双数勾脚设有加强横条时单数勾脚不设加强横条，由于加强横条3的上下错开设置，加强横条3的横向长度可以加长，所有勾脚2上均开设有条形孔4，所述加强横条3固定穿设在条形孔4内，所述加强横条3为弧形板结构。
上述的换向器铜片，加强横条是横向设置的，所以换向器成型时可以与换向器基体之间有更好的结合力，并且，加强横条是上下错开设置的，所以加强横条的横向长度可以加长，更利于与换向器基体的结合强度的加强。
