Abstract

The invention discloses a hydrostatic guideway of a liquid discontinuous flow precise circular turntable, comprising a static guideway, a movable guideway and an oil supply system, wherein the movable guideway is embedded in the static guideway and drives a workbench to rotate, the oil supply system is used for reducing friction between the static guideway and the movable guideway and supplies oil to the static guideway, a plurality of oil pressure chambers communicated with the oil supply system by respective corresponding oil-feeding oil passages are arranged in the static guideway equidistantly, each oil pressure chamber is divided into two parts of an upper oil pressure chamber and a lower oil pressure chamber by the movable guideway, and upper sealing components and lower sealing components are correspondingly arranged in the upper oil pressure chambers and the lower oil pressure chambers respectively. The invention fundamentally eliminates the heating phenomenon of a traditionalhydrostatic guideway and only needs a set of oil sources with very small capacity to carry out intermittent operation. Hydraulic oil is completely sealed, has no inevitable leakage and loss and can not be polluted by the environment, and the invention is a green hydrostatic guideway. The hydrostatic guideway has very high rigidity, and the movable guideway hardly displaces along with the change of load and has very high bias carrying resistance capability.
本发明公开一种液体不连续流动精密圆转台静压导轨,包括有静导轨、嵌入在静导轨内并带动工作台旋转的动导轨、以及为了减少静导轨与动导轨之间的摩擦而向静导轨内供油的供油系统,所述的静导轨内等间距的设置有多个通过各自对应的进油油路与供油系统连通的油压室,所述的每一个油压室都被动导轨分割为上油压室和下油压室两部分,所述的上油压室和下油压室内分别对应设置有上密封件和下密封件。本发明从根本上消除了传统静压导轨的发热现象,只需要一套容量很小的油源间歇工作即可。液压油是完全封闭的,无必然的漏损,也不会被环境污染,是一种绿色静压导轨。静压导轨刚性很高,运动导轨几乎不随负载的变化而发生位移,有很高的抗偏载能力。
