一种数控滚齿机Z轴导向机构

Abstract

本实用新型公开了一种数控滚齿机Z轴导向机构，具体涉及数控滚齿机机床技术领域，包括导向组件,所述导向组件的顶面设置有防偏组件，所述导向组件的正面设置有滑动组件，所述防偏组件包括凹型安装板，所述凹型安装板位于顶部的水平部分顶面固定嵌装有伺服电机，所述凹型安装板的两个水平部分之间转动安装有螺纹竖杆，所述螺纹竖杆的杆身上螺纹套接有螺纹滑块，该数控滚齿机Z轴导向机构通过三个导向竖轴和两组嵌滑块和滑轨可以共同承担导向功能，分摊复合形载荷，有效提升滚齿机在重切时沿Z轴方向移动的精度，同时通过两个定位夹板可以从两侧限制滑动座的横向偏移，起到防偏效果，同时还可不影响滑动座的Z轴方向的升降，实用性更强。
