一种摇臂钻床的辅助立柱
本技术涉及一种摇臂钻床的辅助立柱。
技术介绍
摇臂钻床是广泛运用的通用机床,它操作方便,使用灵活;加工范围大,但因为它是悬臂梁结构布局,所以当主轴箱处于摇臂末端(右端),摇臂又处于上部升程位置时,这是它刚性最差的部位,在这个区位作切削力不大的加工是机床能保证,当切削力逐渐增加,就会出现机床振动、摇臂末端上抬,主轴中心位移等机床刚性不足现象,不但影响加工质量,也影响机床和刀具的使用寿命。
技术实现思路
本技术的目的在于提供一种摇臂钻床的辅助立柱。本技术采用的技术方案是:一种摇臂钻床的辅助立柱,其特征在于:包括底座、立柱、辅助立柱,所述底两端分别垂直设置有立柱、辅助立柱,所述辅助立柱顶部设有配重滚轮架,内部设有重锤,底部固定于托架上,所述托架与底座的连接端设有垫板,所述立柱、辅助立柱之间设置摇臂,所述摇臂与辅助立柱通过角尺板、导套固定连接,所述角尺板设于摇臂端部,所述导套通过螺钉固定于辅助立柱上,所述角尺板与导套的连接处设有带手柄的偏心凸轮,所述偏心凸轮内设置有T型拉杆,外部设有螺套与螺母,所述偏心凸轮内设有定位钢球,所述角尺板上设置夹紧手柄,所述导套靠近角尺板侧设有导向键,所述摇臂上设有主轴箱。所述导套上带有保护圈。所述重锤通过顶部绕于配重滚轮架上的链条与导套连接。本技术的优点:结构简单可靠,操作方便,使用便捷,拆装方便,增强了摇钻的刚度,可以在摇钻刚度最薄弱的摇臂末端位置进行强力切削,组成龙门框架,为发展简易数控坐标钻床创造了最好的基础条件,本结构可适用于多种规格的大型重型摇钻。附图说明下面结合附图和具体实施方式对本技术作进一步详细叙述。图 ...
