Description
Technical field
The utility model relates to a kind of static pressure air-float guide rail, particularly relates to a kind of banded composite throttling pressurized air-float guide rail.
Background technique
At present, the static pressure air-float guide rail used in engineering, only utilizes outer throttling static pressure air-bearing or surface throttle carry out bearing load and provide rigidity, usually runs into that bearing capacity is low, rigidity is little, the problem of poor anti jamming capability in the middle of practical application.The pressurized air guide rail of these kinds does not make full use of composite throttling effect, thus can not provide large bearing capacity and rigidity, and poor anti jamming capability, kinematic accuracy are difficult to improve; Patent (US6164827A) proposes the air floating structure with surperficial very low power, and this structure only just works under little air-film thickness, does not have remarkable effect to raising air supporting block combination property; Patent (TOHKEMY 2009-209962A) proposes the air-float guide rail that the outlet of a kind of flow controller improves, but its improved confinement area only accounts for and makes 6.25% of area, cannot play surface throttle effect.
Summary of the invention
The purpose of this utility model is the composite throttling pressurized air-float guide rail of band shape in order to provide a kind of high rigidity, high bearing capacity.
The purpose of this utility model is achieved in that the guide pin bushing comprising guide rail He be arranged on guide rail outside, described guide pin bushing is spliced by four air supporting plates and forms, two upper and lower air supporting plates arrange an air supporting working surface respectively, two air supporting plates of left and right are arranged respectively two air supporting working surfaces arranged side by side, and between two air supporting working surfaces, pressure relief groove is set, and described pressure relief groove communicates with ambient air, described air supporting working surface neutral position is provided with banded shallow chamber, and neutral position, banded shallow chamber arranges the air vent running through air supporting plate.
The utility model also comprises some structure characteristics like this:
1. two upper and lower air supporting plates arrange the air supporting working surface of two side-by-side parallel.
2. also comprise throttling part, throttling part is installed flow controller in the outlet port of air vent or arrange throttle orifice between the shallow chamber of band shape and air vent.
3. the width in banded shallow chamber described in is the 30%-70% of air supporting face width, and the degree of depth in banded shallow chamber is 1-50 micron.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, and processing cost is low, and the utility model adds banded shallow chamber, form ' endless belt composite throttling mechanism ' structure, improve bearing capacity and rigidity.Compared with traditional static pressure air-float guide rail, the leveling effect of air film to locating face machining error is further enhanced.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Case study on implementation one: composition graphs 1-Fig. 4, the utility model comprises guide rail 1 and is arranged on the guide pin bushing 2 of guide rail 1 outside, described guide pin bushing 2 is by four air supporting plates (upper air supporting plate 3, lower air supporting plate 4, left air supporting plate 5, right air supporting plate 6) splicing composition, upper and lower two air supporting plates 3 and 4 arrange an air supporting working surface respectively, two air supporting plates 5 and 6 of left and right are arranged respectively two air supporting working surfaces 13 and 14 arranged side by side, 16 and 17, and between two air supporting working surfaces, pressure relief groove 15 and 18 is set, and described pressure relief groove communicates with ambient air, described air supporting working surface neutral position is provided with banded shallow chamber 34, banded neutral position, shallow chamber 34 arranges the air vent 35 running through air supporting plate.
Case study on implementation two: based on case study on implementation one, the air supporting working surface 7 and 8,10 and 11 of two side-by-side parallel is also set at two air supporting plates 3 and 4 up and down of the present utility model, and pressure relief groove 9 and 12 is also set between two air supporting working surfaces, and pressure relief groove also communicates with ambient air.
Case study on implementation three: based on embodiment one and embodiment two, and composition graphs 3-Fig. 6, the utility model also comprises throttling part, and throttling part is installed flow controller 36 in the outlet port of air vent 35 or arrange throttle orifice 40 between the shallow chamber 34 of band shape and air vent 35.When arranging flow controller 36, pressure air enters floating gap through air vent 35 and flow controller 36; When arranging throttle orifice 40, pressure air enters floating gap through air vent 35 and throttle orifice 40, and arrange throttling part and can realize throttling, the utility model realizes throttling action by simple structure.
The width in banded shallow chamber described in above-mentioned case study on implementation is the 30%-70% of air supporting face width, and the degree of depth in banded shallow chamber is 1-50 micron.
