Abstract
The utility model relates to a static pressure guide rail, which comprises a shaft, a slider, a fixed plate. The utility model is characterized in that two or more than two circular parallel axis are linked by the fixed board at both ends, the slider is provided with an shaft hole, the gap between the shaft and the slider is the hydraulic oil cavity with a seal ring, the hydraulic oil is fed into the cavity through the restrictor by the oil pump. The utility model has a small friction between the slider and the shaft, which has the advantages of manufacturing easy, adjusting simple and repairing convenient.
Description
One, technical field
The utility model belongs to field of mechanical manufacture technology, specifically is a kind of hydrostatic slideway.
Two, background technology
On lathe,, influence the serviceability of lathe because direct contact type rail friction power is bigger, so general normal employing hydrostatic slideway, but existing hydrostatic slideway generally is V font, square, and its manufacturing, adjustment, maintenance be difficulty, structure is reasonable inadequately, and it is convenient inadequately to use.
Three, technology contents
The purpose of this utility model is at the deficiencies in the prior art, a kind of more reasonable structure is provided, makes and use simpler hydrostatic slideway.
The technical solution of the utility model is as follows:
A kind of hydrostatic slideway comprises axle, slide block, fixed head, it is characterized in that: two parallel circular shaft two ends are connected by fixed head, and the hole of dress axle is arranged on the slide block, and the space of slide block and between centers is a hydraulic fluid chamber.
Hydraulic oil of the present utility model is injected in the hydraulic fluid chamber by flow controller by oil pump, between slide block and hydraulic fluid chamber sealing ring is arranged.
The utility model is full of hydraulic oil owing to adopted circular shaft between axle and slide block, has both reduced the friction of axle with slide block, simultaneously because circular guideway manufacturing, repairing, adjustment are easy, rational in infrastructure, simple and easy to use, and machine tool capability is stablized.
Four, drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Five, the specific embodiment
Embodiment as shown in Figure 1, 2, a kind of hydrostatic slideway comprises axle (1), fixed head (3), and it is characterized in that: two parallel circular shaft (1) two ends are connected by fixed head (3), the hole that the dress axle is arranged on the slide block (2), the space between slide block (2) and axle (1) is hydraulic fluid chamber (4).
Hydraulic oil of the present utility model injects hydraulic fluid chamber (4) by oil pump by flow controller.
Between slide block of the present utility model (2) and hydraulic fluid chamber (4) sealing ring (5) is arranged.
Parallel axes of the present utility model can be more than two.
Claims (4)
1, a kind of hydrostatic slideway, comprise axle (1), slide block (2), fixed head (3), it is characterized in that: two parallel circular shaft (1) two ends are connected by fixed head (3), and the hole of dress axle is arranged on the slide block (2), and the space between slide block (2) and axle (1) is hydraulic fluid chamber (4).
2, according to the described hydrostatic slideway of claim 1, it is characterized in that: hydraulic oil injects hydraulic fluid chamber (4) by oil pump by flow controller.
3, according to claim 1 and 2 described hydrostatic slideways, it is characterized in that: between slide block (2) and hydraulic fluid chamber (4) sealing ring (5) is arranged.
4, according to the described hydrostatic slideway of claim 1, it is characterized in that: parallel axes (1) can be more than two.
