Abstract
The utility model relates to an enclosed air-bearing guide rail, and is characterized in that an upper guide rail, a middle guide rail and a lower guide rail constitute an enclosed air-bearing guide rail mechanism. The mechanism consists of six guide rails and is shaped like two C-shaped mechanisms. The C-shaped mechanism surrounds a fixed guide rail, is connected with an objective table and forms an enclosed guide rail mechanism together with the fixed guide rail. Three types of guide rails (six in total) in the mechanism are provided with intercommunicated air channels, an air faucet is arranged at the exit of each air channel, and an air flow with a certain pressure is led into the air channel. A counterforce is formed among the fixed guide rail and the upper guide rail, the middle guide rail and the lower guide rail under the action of the airflow pressure to ensure that the objective table can move steadily on the fixed guide rail. The steady motion is free from the influence of the weight on the objective table and the airflow pressure, and is applied to a three-coordinate measuring instrument, a shape measuring instrument, a roughness measuring instrument and other precise instruments to improve the measuring precision of the instruments.

Technical scheme
The closed air-float guide rail that the utility model proposes comprises the gas circuit that conduit that guide rail and gas transmission use is formed, and technical characterictic is: described guide rail has two upper rails 5, two middle guides 6, two lower guideways 8 and decides guide rail 7; Upper rail 5 and middle guide 6 and lower guideway 8 are formed the C shape of symmetric shapes, and the device of two C shapes connects to surround by objective table 4 and decides guide rail 7 mouth to mouth; The indoor design of described upper rail 5, middle guide 6 and lower guideway 8 has gas channel, is interconnected in the combination of C shape, adopts gas circuit conduit 10 to connect between two upper rails and connects; The side that gas channel in the described guide rail is decided guide rail 7 has relatively all designed valve 3; 1 design of air inlet road is in the lower end of deciding guide rail 7.
Gas channel on the described upper rail 5 is the through hole that is evenly distributed in this guide rail.
Gas channel on the described middle guide 6 is the one section through hole that is evenly distributed in this guide rail, and top and bottom are not communicated with the outside.
Gas channel on the described lower guideway 8 is the one section through hole that is evenly distributed in this guide rail, the side and the external communications that are connected with middle guide 6, and opposite side is not communicated with the outside.
Uniformity coefficient, the consistent size of the through hole that distributes on described upper rail 5, middle guide 6 and the lower guideway 8.
Beneficial effect
The utility model proposes a kind of closed air-float guide rail, make the measurement of fine measuring instrument, not because the variation of source of the gas, and the dead weight of movable member and the measurement mistake that produces is solved.Use our closed air-float guide rail in the measuring system of exact instrument, exact instrument will no longer rely on the deadweight of movable member so, keep the easy motion of moving part.The inaccurate factor that influences measurement data has reduced, thereby has improved measuring reliability.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
Be illustrated as the synoptic diagram of the closed air-float guide rail of embodiment.
Figure one is a front elevation, and arrow is depicted as the air inlet signal among the figure.Wherein there is screw that middle guide is connected with upper rail, lower guideway, the corresponding connection of gas circuit is arranged in each guide rail.
Figure two is a side view, and the air-flow in the air admission hole enters guide rail through gas circuit, flows to each valve again, and air-flow sprays through valve, shown in synoptic diagram.Screw retention objective table plane on upper rail is wherein arranged, decide guide rail and support platform is fixed.
Figure three is a vertical view, each guide rail of upper, middle and lower be symmetrically arranged in decide the going up of guide rail, about, following four planes.Wherein connect each gas circuit by the conduit of ventilating between two upper rails, make it to communicate.
Gas circuit conduit is in the present embodiment made of the polyethylene pipe word, and the gas circuit of this pipe and each upper rail is connected to form the gas circuit conduit shown in the figure three by the joint of special making.
The middle guide length of present embodiment is 180, and thickness is 12, and width is 54.On the width plane, be evenly equipped with positions, hole such as screw that usefulness is installed, plug, valve.After assembling upper and lower guide rail, all pore Φ 2.5 will form gas channels over against the gas circuit in upper rail, the lower guideway.The screw hole of 2-M3 dark 6 will be used for being connected usefulness with the power system that drags whole closed air-float guide rail, so that total system steadily moves.
The present embodiment middle guide has two upper rails 5, two middle guides 6, two lower guideways 8 and decides guide rail 7; Upper rail 5 and middle guide 6 and lower guideway 8 are formed the C shape of symmetric shapes, and the device of two C shapes connects to surround by objective table 4 and decides guide rail 7 mouth to mouth, is combined into closed state.The gas channel of described upper rail 5 is the through hole that is evenly distributed in this guide rail.The gas channel of middle guide 6 is the one section through hole that is evenly distributed in this guide rail, and top and bottom are not communicated with the outside.Lower guideway 8 gas channel be the one section through hole that is evenly distributed in this guide rail, the side and the external communications that are connected with middle guide 6, opposite side is not communicated with the outside.Uniformity coefficient, the consistent size of the through hole that distributes on upper rail 5, middle guide 6 and the lower guideway 8, and in the combination of C shape, be interconnected, adopt gas circuit conduit 10 to connect between two upper rails and connect.The side that gas channel in guide rail is decided guide rail 7 has relatively all designed valve 3, and 1 design of air inlet road is in the lower end of deciding guide rail 7.
Shown in the figure two, the gas circuit that valve is pressed in upper rail, middle guide, lower guideway and the guide rail forms restriction device, so that air-flow can gush under pressure, and decide guide rail and is formed with reacting force, and the objective table that impels the upper, middle and lower guide rail to form can be steadily mobile along deciding guide rail.
Concrete application is, the gas circuit of the air admission hole access to plant of the gas that has a certain pressure by being arranged in a middle guide, the gas that enters gas circuit carries out the shunting earlier, then by each air flue, enter into upper, middle and lower three class guide rails, gas relies on pressure by being distributed in valve in the three class guide rails, and ejection forms air film rapidly.Upper, middle and lower guide rail three class guide rails with decide guide rail and under the reacting force of this air film, float, the guide rail that floats moves with the power that is applied to it under the effect of upper, middle and lower symmetric arrangement reposefully.Workpiece is arranged on the objective table (movable member), or transducer arrangements just can have been carried out detailed measurement on objective table (movable member).
