Abstract
The utility model discloses a high-precision air static pressure guide rail and belongs to the scope of parts and components of machine tool equipment. The high-precision air static pressure guide rail is a non-contact type sliding guide rail. A cavity is arranged between a sliding block and the guide rail. The cavity is matched with the guide rail, and air with a certain pressure is filled into the cavity. The pressure which is produced by the air supports the sliding block, and then an air film between the guide rail and the sliding block is formed so that the friction energy consumption produced by relative motion is reduced. A static pressure air supply system is started before the guide rail starts , pressure of the static cavity is used for supporting the static guide rail, and then the guide rail is driven by a driving system to achieve movement. The guide rail has the advantages of having small starting torque, no friction, no depletion and no pollution. The guide rail is suitable for various high-precision machine tools and testing equipment.
Description
Technical field
The utility model belongs to the machine tool components range, particularly a kind of high-accuracy aerostatic guide way.
Background technology
The guide rail great majority of traditional machine tool are to adopt being slidably connected of dovetail groove, square groove or circular groove to form the contact rail plate with machine base, in sliding process, between guide rail and machine base, meeting produces frictional dissipation, the guide rail starting torque is large, generally except from piece surface processing fineness guarantees, add lubricating oil or machine oil in order to reduce friction, produce environmental pollution, very unfavorable to workers ' health.
The utility model content
The purpose of this utility model is to adopt the contact mode that is slidably connected for the guide rail of machine tool traditional in prior art and machine base, in sliding process, between guide rail and machine base, meeting produces frictional dissipation, the guide rail starting torque is large, and add lubricating oil or machine oil, produce environmental pollution, to the very disadvantageous deficiency of workers ' health, and propose a kind of high-accuracy aerostatic guide way, it is characterized in that.Between slide block and guide rail, cavity is set.
The cavity arranged between described slide block and guide rail is in two flank side surface or the bottom surface of slide block, and wherein, two flank side surface are for being vertical plane or inclined-plane.
Described guide rail is one or two.
Described guide rail is dove-tail form or square stripe shape.
Described cavity and guide rail.
Described high-accuracy aerostatic guide way is contactless rail plate.
Described guide material is natural granite.
Described slide block is the road and bridge types, and inclined-plane, both sides and bottom surface angle are 45-65
.。
The beneficial effects of the utility model are that this high-accuracy aerostatic guide way is contactless rail plate, and guide rail first plays the dynamic and static pressure air supply system at prestart, utilize the pressure support of static pressure cavity to play static guide rail again by drive systems, realize motion.This kind of guide rail starting torque be little, without friction, lossless, pollution-free, be applicable to all kinds of high-precision machine tools and checkout equipment.
The accompanying drawing explanation
Fig. 1 is high-accuracy aerostatic guide way structural representation.
Fig. 2 is high-accuracy aerostatic guide way overall schematic.
The specific embodiment
The utility model proposes a kind of high-accuracy aerostatic guide way.Below in conjunction with accompanying drawing, be explained
In the high-accuracy aerostatic guide way structural representation shown in Fig. 1, Fig. 2, on slide block 2 one sides between slide block 2 and guide rail 1, cavity 3 is set, at the equidistant fixing hole 4 that arranges of guide rail 1.Described slide block 2 is the road and bridge types, is made of cast iron, and inclined-plane, both sides and bottom surface angle are 55
.。
The skew back face of the both sides at slide block that described cavity arranges, or vertical plane, or bottom surface, described guide rail is dove-tail form or square stripe shape one or two.Cavity and guide rail must mate.
Described guide material is the high accuracy natural granite.Because natural granite has good characteristic, can make precision and be: the flatness of 0.002mm/m2, make this kind of aerostatic guide way X-direction linearity can reach 0.00015/150mm: the more conventional aerostatic guide way of precision is better; This high-accuracy aerostatic guide way is contactless rail plate, guide rail first plays at prestart the air that the dynamic and static pressure air supply system is filled with certain pressure in cavity, supply gas pressure: 4.5MPa-5.5MPa, air mass flow: 0.3m3/min.Make between guide rail and slide block and form air film, the pressure support slide block produced with air, reduce the friction energy loss that both relative motions produce; Utilize the pressure support of static pressure cavity to play static guide rail again by drive systems, realize motion.This kind of guide rail starting torque be little, without friction, lossless, pollution-free, be applicable to all kinds of high-precision machine tools and checkout equipment.
The more conventional rectangular closed formula of the high-accuracy aerostatic guide way of dove-tail form shown in Fig. 1 guide rail has three advantages:
A. increased the integral rigidity of rail sections;
B. reduced arrangement space
C. adjust Y, the Z-direction gap is more convenient
D. reduced the difficulty of processing of slide block
E. the Y of this kind of aerostatic guide way, the integral rigidity of Z-direction have been increased.
