Abstract

本发明涉及取出断螺钉的工具，包括圆柱形的钻头部，所述钻头部端面具有楔形部，所述楔形部由平行于轴向的竖向面和倾斜于端面的斜向面形成，竖向面与斜向面夹角为50～80°，且夹角点所在连接线为楔尖线，所述楔尖线平行于钻头部端面，且楔尖线设置有尖齿。上述取出工具，在端面设置有楔形部，楔形部的尖部设置尖齿，工具抵紧断螺钉端面反螺纹旋转，尖齿可以刺入断螺钉端面，借助刺入的卡阻力度带动螺钉旋松取出。

Description

取出断螺钉的工具
技术领域
本发明涉及便于取出断螺钉的工具。
背景技术
对于机械设备的螺钉连接部分，某些螺钉受到过大的剪切力，会发生断裂。此时螺钉不能按照正常的螺纹拆卸方式拆除，导致螺钉无法更换，现行的处理方式，需要在断螺钉端部钻孔，然后用工具卡入孔中才能将螺钉取出，操作非常不便。
发明内容
本发明所要解决的技术问题是：提供一种取出断螺钉的工具，不用钻孔，即可将断螺钉取出。
本发明解决其技术问题所采用的技术方案是：
取出断螺钉的工具，包括圆柱形的钻头部，所述钻头部端面具有楔形部，所述楔形部由平行于轴向的竖向面和倾斜于端面的斜向面形成，竖向面与斜向面夹角为50～80°，且夹角点所在连接线为楔尖线，所述楔尖线平行于钻头部端面，且楔尖线设置有尖齿。
进一步的，所述钻头部端面设置有四个楔形部，所有楔形部沿端面所在圆圆心旋转对称。
本发明的有益效果是：上述取出工具，在端面设置有楔形部，楔形部的尖部设置尖齿，工具抵紧断螺钉端面反螺纹旋转，尖齿可以刺入断螺钉端面，借助刺入的卡阻力度带动螺钉旋松取出。
附图说明
图1是本发明的取出工具的立体示意图；
图中附图标记为：钻头部1、楔形部11、竖向面111、斜向面112、楔尖线113、尖齿12。
具体实施方式
下面结合附图和实施例对本发明进一步说明：
取出断螺钉的工具，包括圆柱形的钻头部1，所述钻头部1端面具有楔形部11，所述楔形部11由平行于轴向的竖向面111和倾斜于端面的斜向面112形成，竖向面111与斜向面112夹角为50～80°，且夹角点所在连接线为楔尖线113，所述楔尖线113平行于钻头部1端面，且楔尖线113设置有尖齿12。
如图1所示，本发明的工具可以像钻头一样安装在电钻上，让工具端部伸入断螺钉的孔，楔形部11的楔尖线113抵紧断螺钉端面，启动电钻带动工具向反螺纹方向旋转，则楔尖线113的尖齿12可以刺入断螺钉端面，产生阻力和摩擦力，进而带动断螺钉反螺纹方向转动，从螺纹孔旋松退出。
钻头部1的楔形部11数量根据需要可以是两个、三个或更多，优选的是，钻头部1端面设置有四个楔形部11。要求所有楔形部11沿端面所在圆圆心旋转对称，根据螺钉螺纹方向不同，设置楔形部11的楔尖线113是顺时针排布或是逆时针排布。
楔尖线113平行于钻头部1端面，可以增大与螺钉的接触面积，增大持力。便于旋转力矩传递至断螺钉。
