Abstract

六角柄麻花钻头。本实用新型涉及金属切削加工工具，尤其涉及一种快速装卸的钻头。本实用新型由钻头和六角形柄组成，柄部设有环形圆弧槽，圆弧槽的截面轮廓线为半径2.4～2.8mm的劣弧，环的中心线距柄端的距离为13.7～14.3mm，柄的长度为上述距离的3倍。本实用新型的六角柄麻花钻头结合标准快换钻夹头，将定位槽位置进行了优化改进，使得装夹更可靠；上述定位槽的设置还会使得钻头的上端面与快换钻夹头的孔的底面接触，减小钻头上环形槽和夹头钢珠承受的轴向力，延长快换钻夹头的使用寿命；定位圆弧槽的劣弧设计，可方便钢珠嵌入、脱离，使得装卸更方便；另外本实用新型的六角柄麻花钻头还能在普通钻夹头上使用。

Description

六角柄麻花钻头
技术领域
本实用新型涉及金属切削加工工具，尤其涉及一种快速装卸的钻头。
背景技术
目前的钻头装夹柄，其截面形状一般是圆形、六角形、正方形或带倒角的三角形。使用时，通常和普通的扳手三爪钻夹头配合使用，扳手三爪钻夹头是通过旋转扳手带动一个螺母旋转，使夹爪夹紧钻头。当需要频繁更换不同规格钻头时，每次的拆卸都要耗费大量时间、人力，工作效率很低。一种快速装夹头解决了以上的问题，其原理主要是通过定位珠实现对钻头的定位，在钻头的柄上开设一圆弧槽，用于配合上述的定位珠。但由于麻花钻生产的标准化程度低，在目前通用的快速装夹头中经常会出现定位不可靠的问题，造成钻头松脱、打滑的现象。
发明内容
针对以上问题，本实用新型提供一种适用于快换钻夹头，工作时定位可靠，装卸方便的六角柄麻花钻头。
本实用新型的技术方案是：由钻头和六角形柄组成，柄部设有环形圆弧槽，圆弧槽的截面轮廓线为半径2.4~2.8mm的劣弧，环的中心线距柄端的距离为13.7~14.3mm，柄的长度为上述距离的3倍。
本实用新型的六角柄麻花钻头结合标准快换钻夹头，将定位槽位置进行了优化改进，使得装夹更可靠；上述定位槽的设置还会使得钻头的上端面与快换钻夹头的孔的底面接触，减小钻头上环形槽和夹头钢珠承受的轴向力，延长快换钻夹头的使用寿命；定位圆弧槽的劣弧设计，可方便钢珠嵌入、脱离，使得装卸更方便；另外本实用新型的六角柄麻花钻头还能在普通钻夹头上使用。
附图说明

图2是图1中A-A视图
具体实施方式
在钻头1的柄部2开设环形圆弧槽3，圆弧槽3的截面轮廓线为半径2.4~2.8mm的劣弧，这样能使定位珠进入和分离便捷；环形圆弧槽3的中心线距柄部2端头的距离为13.7~14.3mm，柄部2的长度为上述距离的3倍。
