Abstract
The utility model discloses a sealed type oil return structure for a hydrostatic guide rail. The sealed type oil return structure comprises a hydrostatic oil cavity arranged on a working face of the guide rail and an annular oil return cavity around outside the hydrostatic oil cavity. An annular groove is further arranged outside the annular oil return cavity; and an air inlet channel for inputting compressed air in the annular groove is further arranged on the guide rail. The sealed type oil return structure for the hydrostatic guide rail provided by the utility model fills the compressed air into the annular groove, so that a high-pressure annular air curtain is formed outside the annular oil return cavity. The high-pressure annular air curtain can prevent hydrostatic oil in the annular oil return cavity from flowing out, and can stop external cooling oil from entering the annular oil return cavity. Accordingly, the sealing structure can prevent the hydrostatic oil and the cooling oil from being mixed, prevents the hydrostatic oil from being leaked, and has the advantages of simple sealing structure and low manufacture cost.
Description
Technical field
The utility model relates to a kind of hydrostatic slideway, particularly a kind of hydrostatic slideway static pressure oil oil return structure.
Background technology
There is a shortcoming in the lathe of available technology adopting hydrostatic slideway in processing work: the static pressure oil that promptly is used to support hydrostatic slideway mixes with the cold oil that is used to cool off workpiece easily.
The solution of the problem of mixing to static pressure oil and cold oil at present has two kinds: 1, on guide rail installation carrier, special anti-loading in mixture is set and puts, but complex structure, and cold oil splashes in process, be difficult to guarantee fully that cold oil and static pressure oil do not mix; 2, through external discrete equipment mixed static pressure oil is separated with cold oil, but the external discrete equipment price is expensive, separation costs is high.
Therefore the mode that needs a kind of new solution static pressure oil and cold oil to mix, preventing the mixed problem of static pressure oil and cold oil more completely, and the reduction input cost.
The utility model content
In view of this; The purpose of the utility model provides a kind of hydrostatic slideway enclosed oil return structure; It has simple in structure, low cost of manufacture and characteristics such as anti-static pressure oil and cold oil good mixing effect, can solve hydrostatic slideway lathe static pressure oil and hydraulic oil mixed problem in the prior art.
The utility model hydrostatic slideway enclosed oil return structure; Comprise the static pressure oil pocket annular oil back chamber outer that is arranged on the working face of guide rail with being surrounded on the static pressure oil pocket; Outside annular oil back chamber, also be provided with an annular groove, also be provided with the compressed-air actuated inlet channel of input in annular groove on the guide rail.
Further, said inlet channel is provided with two to four inflation inlets of in annular groove, inflating, and said inflation inlet is circumferentially evenly arranged along annular groove.
The beneficial effect of the utility model: the utility model hydrostatic slideway enclosed oil return structure; In annular groove, charge into compressed air; Thereby can outside annular oil back chamber, form a high pressure circular curtain, the high pressure circular curtain can stop the static pressure oil in the annular oil back chamber to flow out, also can stop extraneous cold oil to get into annular oil back chamber; Therefore this hermetically-sealed construction can prevent that static pressure oil and cold oil from mixing, and stop the leakage of static pressure oil, and hermetically-sealed construction is simple, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the front view of the utility model hydrostatic slideway enclosed oil return structure;
Fig. 2 is the zoomed-in view of P portion among Fig. 1;
Fig. 3 is the cutaway view of Fig. 2 along A-A.
The specific embodiment
Fig. 1 is the front view of the utility model hydrostatic slideway enclosed oil return structure; Fig. 2 is the zoomed-in view of P portion among Fig. 1; Fig. 3 is the cutaway view of Fig. 2 along A-A.
As shown in the figure; Present embodiment hydrostatic slideway enclosed oil return structure; Comprise static pressure oil pocket 1 that is arranged on the working face of guide rail and the annular oil back chamber 2 that is surrounded on outside the static pressure oil pocket 1; Outside annular oil back chamber 2, also be provided with an annular groove 3, also be provided with the compressed-air actuated inlet channel 4 of input in annular groove 3 on the guide rail.
During work, in annular groove 3, charge into compressed air through inlet channel 4 earlier, charging into static pressure oil to static pressure oil pocket 1 through static pressure oil oil inlet passage 5.The gap of static pressure oil between guide rail and guide rail carrier flows into the annular oil back chamber 2, and the static pressure oil in the annular oil back chamber 2 flows back in the lathe oil return storage chamber through drainback passage 6 again.Because the gases at high pressure in the annular groove 3 have formed the high pressure gas curtain one in annular oil back chamber 2 outsides, thereby can stop the static pressure oil in the annular oil back chamber 2 to flow out from the gap between guide rail and guide rail carrier, also can stop extraneous cold oil to get into annular oil back chamber.Therefore this hermetically-sealed construction can prevent that static pressure oil and cold oil from mixing, and stop the leakage of static pressure oil, and hermetically-sealed construction is simple, low cost of manufacture.
In the present embodiment, said inlet channel 4 is provided with two inflation inlets of in annular groove, inflating, and two inflation inlets evenly arrange circumferentially that along annular groove two even layouts of inflation inlet can make the gas curtain of formation more even, and sealing effectiveness is better.Certainly in different embodiments, the quantity of air-filled pore can be adjusted as required, and operated by rotary motion 2-4 comparatively suitable.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
