The invention discloses a vertical static-pressure guide rail and an oil return device. The device comprises a Z-axle slide table, an oil receiving disc, front guide rails, side guide rails, back guide rails, a Y-axle base, oil seals, a slide table and a support block, wherein the support block is mounted at one end of the Z-axle slide table; the Y-axle base is mounted on the support block; the oil receiving disc is mounted at the other end of the Z-axle slide table for supporting oil flowing back from the guide rails to flow into an oil tank; two front guide rails are mounted on two sides of the oil receiving disc; two back guide rails are also mounted on the oil receiving disc, and are contacted with the end surface of the Y-axle base; two side guide rails are mounted between the front guide rails and the back guide rails; the slide table is mounted between the front guide rails and the back guide rails, and is positioned between the two side guide rails to form a static-pressure guide rail with a closed structure; two oil seals are mounted at the upper end of the slide table to realize oil distribution to each oil cavity of the slide table. The vertical static-pressure guide rail and oil return device is low in frictional force, high in rigidity, high in guiding precision and high in bearing capacity.
Description
technical field [0001] The invention is a vertical static pressure guide rail and an oil return device, which belongs to the innovative technology of the vertical static pressure guide rail and the oil return device. Background technique [0002] Ultra-precision machine tools are the primary basic conditions for ultra-precision machining, and guide rail components are key components in ultra-precision machine tools, and their performance largely determines the accuracy of ultra-precision machine tools. At present, there are mainly two types of vertical Y-axis guide rails in China, sliding guide rails and linear guide rails, which are used as guiding mechanisms. The frictional force is large and the guiding precision is low, which limits the development of ultra-precision CNC machine tools. [0003] Hydrostatic guide rails are divided into open type and closed type, which are mainly used in ultra-precision equipment technology. The development of precision and ultra-precisio...
