Abstract

一种用于加工带内花键类零件用的芯轴，其技术 方案要点是筒形弹性瓣卡的下部槽中装有二片可由 胀杆分开的半键，筒内有一下端带有锥形头部的胀 杆，并依次装有胀套、弹簧、钢球、压套、钢球、上压套、 钢球和螺母。使用本实用新型可以高精度、高效率的 加工带内花键的零件。

Description

本实用新型涉及一种机床零件，特别是一种内花键零件用芯轴。
现有技术如中国专利CN88216959.9“内花键键侧磨床”中用来固定加工零件用的芯轴，是采用弹性瓣卡，下端由锥柄与回转工作台固定。由于固定零件时瓣卡只有上端与零件接触，因此定位精度不够高，下端由锥柄固定无定位装置，初始定位工作比较麻烦，效率不够高。
本实用新型的目的是提供一种高精度、高效加工带内花键零件用芯轴。
本实用新型的目的是这样实现的：筒形弹性瓣卡的下部槽中装有二片可由涨杆分开的半键；筒内有一下端带有锥形头部的涨杆，并依次装有涨套、弹簧、钢球、压套、钢球、上压套、钢球和螺母；筒形弹性瓣卡的花键至少有两个键中间有通槽。
以下结合附图对本实用新型作进一步说明。
图1是本实用新型一种具体实施例的主剖视图。
图2是图1的A向局部视图。
图3是图1的俯视图。
图4是图1的外观图。
图5是图3沿B－B的剖视图。
在图1－5中，筒型弹性瓣卡8下端开口槽中安有二个半键11，弹性瓣卡8的内部有上端带螺纹、下端是锥形头部的涨杆10，并依次安装有涨套9、弹簧7、钢球6、压套5、钢球4、上压套3、钢球2和螺母1。弹性瓣卡8的上部外表面制成花键形，有两个以上相对键中间开口。涨套8的下端带有锥面，上压套3和压套5外圆有倒角，钢球2、4和6分别放在螺母、上压套3与压套5外表面倒角间形成的槽内。工作时，先将半键11放入回转工作台4的中心孔中，需要加工的零件放在弹性瓣卡8上部。旋转螺母1，通过钢球2、4、6和上压套3、压套5、涨套9与涨杆10的锥形头部共同涨开瓣卡11，使芯轴能精确地固定在回转工作台上，随着螺母的继续旋转，上压套3和压套5的倒角推动钢球2、4、和6使弹性瓣卡8的卡瓣涨开，紧固住零件。相反方向旋转螺母，就可以取下零件和芯轴。
使用本实用新型芯轴可以快速地、精确地固定住零件，并且可以很方便地取下芯轴，因此可以提高加工带花键零件的生产效率。
