Abstract
The present invention belongs to the field of machine building technology, and is especially one kind of mixed guide rail. The horizontally set mixed guide rail includes closed static pressure vertical guide rail and sliding horizontal guide rail with high rigidity, and has reduced friction, especially in vertical direction, and raised rigidity, mainly in horizontal direction. The mixed guide rail with well combined closed static pressure vertical guide rail and sliding guide rail has reasonable structure, less friction, high regulation precision, high rigidity and relatively low cost.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of mixed type guiding rail.
Background technique
Closed hydrostatic slideway is a kind of guide rail of function admirable, and its principle is to utilize oil film to isolate frictional force is dropped to minimum, thereby improves the precision of guide rail, but its manufacture cost is higher, and rigidity is also not as slide guide; And the frictional force of slide guide is big, and the vibration of creeping is big, and guide precision is not enough, and the life-span is also short, and the problem that these aspects exist is difficult to solve, up to the present also do not have a kind of can be with the scheme of the effective combination of both advantages.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of precision height, good rigidly, the effective more scientific and reasonable mixed type guiding rail that combines of hydrostatic slideway and slide guide.
On general lathe, the guide rail of horizontal positioned is different in the frictional force of Vertical direction and substantially horizontal, because will bear the pressure of other parts on moving railing and workpiece or the lathe perpendicular to its guide rail of Vertical direction of horizontal plane, its rail friction resistance is also bigger, but the power of bearing in the horizontal direction is cutting force often, so frictional force is just less in the horizontal direction.
According to above characteristics, technological scheme of the present invention is as follows: adopt mixed type guiding rail on the guide rail of horizontal positioned, promptly adopt closed hydrostatic slideway in Vertical direction, adopt the better rigidity slide guide in the horizontal direction, so both can reduce friction (mainly in Vertical direction), can improve rigidity (mainly in the horizontal direction) again.
The present invention since with closed hydrostatic slideway and slide guide basis separately characteristics combine with performance is effective, make mixed type guiding rail more scientific and reasonable, compare with common slide guide, its frictional force is little, degree of regulation is higher, performance is more superior; Compare with closed hydrostatic slideway completely, rigidity is better, and cost reduces.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Embodiment
As shown in Figure 1, a kind of mixed type guiding rail is characterized in that: on the guide rail of horizontal positioned, Vertical direction adopts closed hydrostatic slideway, and promptly deciding has static pressure oil pocket 3 between guide rail 1 and the moving guide rail 2, can reduce friction; Adopt the better rigidity slide guide in the horizontal direction, promptly moving guide rail 2 slides in the chute 4 of deciding guide rail 1, can improve the guide rail rigidity.
