Description

一种钻孔辅具 技术领域
本发明涉及一种钻孔辅具，属于机床附件技术领域。
背景技术
许多轴类零件，需要在外圆钻一个或若干个通过直径位置的孔，为了防止所钻的孔偏离直径位置，一般需要对钻床做特别的调整，同时采用专门的工装来实现定位的目的，这类工装不但结构复杂，尤其存在通用性较差的缺陷，致使工装品种较多，提高了零件的加工成本，尤其不适用多品种小批量零部件的生产制造。
发明内容
本发明的目的在于：针对现有技术中所存在的上述缺陷，本发明提供一种钻孔附件，在钻轴类零件外圆上通过直径位置孔时，使用该种钻孔辅具，不但能够提高劳动的生产率、降低零件的制造成本、尤其具有通用性较好的优点。
本发明实现上述目的所采用的技术方案是：所述的一种钻孔辅具，它是由锥度柄(1)、第一转轴(2)、U型连接头(3)、刻度线(4)、指针(5)、固定螺母(6)、第二转轴(7)、第一轴承(8)、跨接脚(9)、第二轴承(10)、止转键(11)所组成，所述的U型连接头(3)是字母U字型结构，第二转轴(7)通过第一轴承(2)与第二轴承(3)可旋转地安装在U型连接头(3)的开裆两侧的平面上，在U型连接头(3)的开裆之间的第二转轴(7)上通过止转键(11)固定安装有 跨接脚(9)，所述的跨接脚(9)是一个等边的内角结构，所述的跨接脚(9)两个边内侧是平面型结构，在第二转轴(7)其中一端用固定螺母(6)固定安装有指针(5)，在指针(5)所对应部位的U型连接头(3)的平面上制有刻度线(4)，在U型连接头(3)的中心轴线处于垂直状态下，跨接脚(9)两个边所组成角的角平分线与U型连接头(3)的中心轴线重合，同时，指针(5)指向刻度线(4)的中点，在U型连接头(3)结合部中心位置，可旋转地设置一个第一转轴(2)，所述的第一转轴(2)顶部突出部分、通过螺纹连接的方式与锥度柄(1)的底部中心连接固定在一起。
本发明的使用过程与使用方法是：预先将待加工的轴类水平地安装固定在钻床的工作台上，将部分的装置通过锥度柄(1)安装在钻床安装钻头的主轴孔内，调整钻床的摇臂与主轴的位置，使跨接脚(9)两个边跨骑在待加工工件的外圆上，进一步地调整钻床的摇臂与主轴的位置，使指针(5)指向中间位置，此时，钻床的主轴轴线通过工件的直径位置，此时，将机床锁定，将本装置卸下并换上钻头，就可以加工。
有益效果：由本发明的使用过程以及使用方法可知，本发明能够使用不同直径的工件，而且调节效率较高，所以，本发明够提高劳动的生产率、降低零件的制造成本、尤其具有通用性较好的优点。
