Abstract

在车床尾座的底部安装了四个受力后可上下移动的滚动轴承,当需固定尾座时,旋紧固定手柄,四轴承克服弹力向上移动,尾座底面与床身导轨面接触,尾座被固定。松开紧固手柄,四轴承受弹力下移露出尾座底面,此时可轻便移动。

Description

车床尾座
本实用新型是一种车床尾座,供车床加工时用。
目前使用的车床尾座,在使其移动时,其底座在车床导轨上滑动,因而存在如下缺点:(1)摩擦力较大,操作者易疲劳,从而影响工作效率;(2)磨损快,降低车床加工精度。
本实用新型的目的是提供一种改滑动为滚动的车床尾座,能达到既省力(提高效率)又可减轻磨损(保证精度)的目的。
本实用新型的目的是这样实现的,在尾座底座的下方,即与车床床身导轨接触(滑动)的一面,按装四个滚动轴承,在推拉尾座时,滚动轴承在床身导轨上滚动,从而使尾座轻便地移动。
本实用新型与现有技术相比具有的优点是:(1)改滑动为滚动后,摩擦力减小,使用轻便,可提高效率;(2)可减轻磨损,减缓车床精度的降低。
以下结合附图和实施例作详细描述。
图1是车床尾座的结构示意图
车床尾座的结构如图所示,在尾座底座(2)上,加工四个孔,孔内按劳轴承架10,轴承8用轴肖9按装在轴承架上,轴承架上端按装弹簧11,调整螺母12与轴承架以螺纹联接,旋转调整螺母可调整弹簧弹力和轴承按装高度。当需紧固尾座时,旋转紧固手柄4使偏心轴5转动,从而使连接杆6带动固定块7上移,固定块与床身1导轨底面接触。当继续旋紧紧固手柄时,连接杆对尾座产生拉力,尾座的四个轴承受力后,克服弹簧弹力向上移动,直至尾座底板的下面与床身导轨的上面接触,即整个尾座紧固在床身导轨上。
当尾座需移动时,松开紧固手柄,弹簧将尾座托起,即四个轴承露出尾座底板的底平面,尾座即可轻便移动。
该尾座可按装四个轴承,按装其它数量的轴承也可达到上述之目的。
该尾座主要应用在车床上,也可应用于有类似车床尾座的其它机床上。
