Description
Technical field
The utility model relates to a kind of straight line and uses the ball hydrostatic slideway, specifically is applicable to the mechanism that requires to have relative straight line between two members, belongs to the frame for movement technical field.
Background technology
Along with the high speed development of China's mechanical industry, especially under big load to straight-line demand, hydrostatic slideway is had higher requirement.Concerning hydrostatic slideway, how to raise the efficiency, reduce dry friction, reduce to drive power become pendulum at each rectilinear motion with hydrostatic slideway manufacturer significant problem in front.
There are shortcomings such as precision is not high, difficulty of processing is big, oil film is inhomogeneous, have dry friction, efficient is lower, required driving power big, the high-precision control difficulty of realization is big, the fluid consumption is big, oil contamination is big in existing straight line hydrostatic slideway.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby provides a kind of rectilinear motion to use the ball hydrostatic slideway, utilizes the sphere contact to replace traditional plane contact; Reduced difficulty of processing; Use 5 oiling modes, guaranteed the uniformity of hydrostatic slideway oil film under uneven loading action, can also be according to the number and the installation site of magnitude of load and application point selection way block; Thereby improved the precision of hydrostatic slideway under the load effect, guaranteed higher instructions for use.
The technical scheme of the utility model is that a kind of rectilinear motion is used the ball hydrostatic slideway, the rolling supporting sephere that it is characterized in that in way block ball chamber, packing into composition way block assembly; Sealing block is installed on the line slideway through bolt, forms the line slideway assembly; The way block assembly is packed on the line slideway assembly, and the rolling supporting sephere is stuck in the ball path groove of line slideway; At the way block two ends oil scraping plate is housed; Form labyrinth sealing through sealing block between line slideway and the way block.
In the said way block upper surface rectangular channel and near the ball chamber drainback passage is arranged, said way block ball has five oil inlet passages in the chamber.
The utlity model has simple in structure, compact in design, advantages such as the hydraulic oil consumption is little, hydraulic oil pollution is little, load is big, precision is high, processing technology is simple, easy accessibility; Problem such as solved that plane contact hydrostatic slideway oil film is uneven, difficulty of processing is big, efficient is low, distortion is big when heavily loaded, guaranteed hydrostatic slideway efficient, steadily, the high accuracy running.
The utility model adopts hydraulic circuit control simultaneously, has improved production efficiency and has realized automation control; Reduce the friction between rolling supporter and the way block, prolonged service life; Reduced the influence of unbalance loading to oil film thickness; Improved its impact resistance.
Description of drawings
Fig. 1 is the utility model structure general assembly drawing.
Fig. 2 is the utility model way block structural representation.
Fig. 3 is the utility model oil scraping plate structural representation.
The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise way block 1, rolling supporting sephere 2, sealing block 3, line slideway 4, oil scraping plate 5, drainback passage 6, oil inlet passage 7 etc.
In way block 1 ball chamber, pack into rolling supporting sephere 2 of the utility model is formed slide block assemblies; Sealing block 3 is installed on the line slideway 4 through bolt, forms the line slideway assembly; Slide block assembly is packed on the line slideway assembly, and rolling supporting sephere 2 is stuck in the ball path groove of line slideway 4.
Said way block 1 upper surface has the ball chamber, and rolling supporting sephere 2 is contained in wherein during installation, and rolling supporting sephere 2 is played positioning action.There is ball path groove on said line slideway 4 surfaces, during relative way block 1 rectilinear motion of line slideway 4, rolling supporting sephere 2 are freely rolled in ball path groove, have replaced common plane contact with the sphere contact.
There is drainback passage 6 to insert oil return pipe respectively in the said way block 1 upper surface rectangular channel and near the ball chamber, can reclaims the fluid that overflows, reduce fluid and receive external pollution.
Said way block has five oil inlet passages 7 to insert oil inlet pipe respectively in the 1 ball chamber; Fluid is got in the ball chamber from five directions,, between rolling supporting sephere 2 and way block 1, form oil film so that pressure oil gets into; Make rolling supporter stress balance, can bear big unbalance loading.
Have rectangular channel on the said way block 1, with the sealing block 3 formation labyrinth seals on the line slideway 4, the side direction that can hinder fluid is overflowed, and is convenient to the recovery of fluid.
The utility model adopts piecemeal to install, and can choose the quantity and the installation site of way block according to need of load.Circulation in the fluid, the pollution problem that has solved fluid.Way block 1 adopts 5 oiling modes, and the rolling supporter still is in the center when guaranteeing unbalance loading.
The operation principle of the utility model and the course of work:
Rectilinear motion is seated with the ball hydrostatic slideway; When needing line slideway 4 with way block 1 relative motion, pressure oil pressurization back gets in the ball chamber of way block 1 jack-up rolling supporting sephere 2 through oil inlet passage 7; Under load gravity and hydraulic fluid pressure effect; Form uniform oil film between way block 1 and the rolling supporting sephere 2, the dry friction when having avoided line slideway 4 motions between rolling supporting sephere 2 and the way block 1 has improved efficient greatly; Fluid gets into oil return pipes through drainback passage 6, thereby gets into fuel tank, through becoming pressure oil after the oil pump pressurization, the fluid recycle, environmental protection, pollute little.
When needing line slideway 4 and way block 1 static relatively, the pressure oil pressure release, because action of load gravity, line slideway 4 is got back to the origin-location with rolling supporting sephere 2, accomplishes an operation cycle.
