Specific embodiment
Below in conjunction with the accompanying drawings and example is specifically described to the utility model.
Fig. 1 show structural representation of the present utility model.
The utility model includes slide carriage 1 and ram 4.
The ram 4 is square ram, and the ram 4 is provided with eight guide pass 13, installs quiet between slide carriage 1 and guide pass 13
Pressure guide-rail plate 2, is left on hydrostatic slideway plate 2 and static pressure oil film is formed in static pressure area 11, static pressure area 11, and static pressure oil film is imitated by pumping
Should, play cushioning effect.
The guide pass 13 of the ram carries out integral grinding on slideway grinder, meets each guide pass parallel or vertical
It is required that.
There is pressure detecting in the static pressure area 11, pressure gauge reading shows the pressure value in static pressure area in real time.
Fig. 2 show A of the present utility model to schematic diagram.
The slide carriage 1 is provided with front pressuring plate 5.
Between the leading flank and front pressuring plate 5 of the ram 4, gap adjustment block 6 is installed between right flank and slide carriage 1, leads to
Adjustment gap adjustment block 6 is crossed, fore-and-aft direction, the thickness of the static pressure oil film of left and right directions can be adjusted, make each side static pressure of ram 4
Oil film thickness uniformity in area 11, and cause that oil film rigidity reaches maximum.
Static pressure oil is ceaselessly cycling in and out by internal EGR, serves the effect for reducing the temperature rise of ram 4.
Fig. 3 show I portions of the present utility model enlarged diagram.
The lower end of the slide carriage 1 is provided with swab case 12.
Guide rail scraper plate 7 and oil-resistant rubber strip 8 are installed in the upper end of the slide carriage 1, and oil scraping plate 9, the and of oil-resistant rubber strip 8 are installed in lower end

Direct oil return is to system fuel tank.
The ram 4 installs oil guard 3 along its length, it is ensured that static pressure oil is on guide pass 13.
Operation principle of the present utility model and specific：
1) it is provided with clearance adjusting unit by ram leading flank and right flank so that rub system between ram and slide carriage
Number is small, it is possible to be adjusted to suitable oil film thickness, makes oil film thickness uniformity in each side static pressure area of ram, and cause oil
Film rigidity reaches maximum；
2) multiple stationary. platens are set in each side of ram, static pressure area area is big, big with ram contact surface, be adapted to it is high-power,
High pulling torque cuts, and effectively improves the flexural deformation of ram when high pulling torque is processed, it is ensured that machine tool accuracy；
3) increase of the dynamic rate of hydrostatic slideway with the increase of the frequency of oscillation on supporting surface quickly.This
Planting vibration has pumping effect, alternately increases and reduce the output flow of hydrostatic slideway, and it may stop in moment or even change
Liquid flow path direction, because it wants consumed energy, this energy is then transformed into the form of heat and dissipates again, therefore must block vibration,
Hydrostatic slideway can play cushioning effect, while the dynamic property of whole lathe is improved, will also improve the machining accuracy of part.
The utility model the embodiment above, is merely illustrative, be not it is only, it is all in the range of the utility model
