Abstract

本发明公开了一种镗杆导向装置,包括铣轴,铣轴上装导向长键,在铣轴的端部设置二个增加导向长度的导向端面键。本发明结构合理,极大地增加了导向长度,从而确保镗杆的直线运动精度。

Description

镗杆导向装置
技术领域
本发明涉及一种镗床的镗杆导向装置。
背景技术
在镗床中,镗杆需沿铣轴作Z轴向的直线进给运动,铣轴一般是通过2个导向长键来传递该直线进给运动的,导向长键越长,其能传递的直线运动精度就越高,但由于受其结构制约,导向长键的长度受到一定的限制。
发明内容
本发明的目的在于提供一种结构合理,确保镗杆直线运动精度的镗杆导向装置。
本发明的技术解决方案是:
一种镗杆导向装置,包括铣轴,铣轴上装导向长键,其特征是:在铣轴的端部设置二个增加导向长度的导向端面键。
本发明结构合理,极大地增加了导向长度,从而确保镗杆的直线运动精度。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明一个实施例的结构示意图。
具体实施方式
一种镗杆导向装置,包括铣轴1,铣轴上装导向长键2,在铣轴的端部设置二个增加导向长度的导向端面键3。图中还要镗杆4、齿轮5、滑枕6、轴承7。
