Abstract
The invention relates to a supporting roller floating-type static pressure centre frame. The centre frame consists of a shell (1), static pressure supporting blocks (8, and 2), supporting rollers (6, and 4), driving devices (9, and 10), limiting plates (11, and 12), oil intake pipelines (7, and 3) and an oil discharge pipeline (13). The supporting roller floating-type static pressure centre frame is characterized in that the supporting surfaces of the upper and lower static pressure supporting blocks (8, and 2) are respectively provided with a static pressure oil cavity (16), the upper and lower supporting rollers (6, and 4) are respectively arranged on the static pressure oil cavity supporting surfaces of the upper and lower static pressure supporting blocks (8, and 2), and a workpiece (5) is arranged and supported on the upper and lower supporting rollers (6, and 4) to be supported. When rotating, the workpiece can drive the upper and lower supporting rollers (6, and 4) to rotate. Because the upper and lower supporting rollers (6 , and 4) are subjected to static pressure supporting, and therefore the supporting roller floating-type static pressure centre frame has the characteristics of small friction force, low vibration and durability.
Description
Technical field
The present invention relates to the support of workpiece, the especially support of many diameter specifications roll, particularly a kind of static-pressure central frame of supporting roller floating type.
Background technology:On roll grinder, common centre frame comprises two kinds of static-pressure central frame and slip centre frames.The static pressure supporting surface of static-pressure central frame is circular arc, and a static pressure supporting surface can only directly match with a kind of roller and could form hydrostatic effects, and therefore the specification of how many roll diameter of roller is arranged, and just needs the different static pressure tray of configuration how many kinds of.The slip centre frame is directly contacted with supporting surface by roll, and vibration is large, and it is comparatively serious to wear and tear, and therefore needs often to change tray, thereby causes the waste of material.Therefore, how to design a cover centre frame, realize that it without wearing and tearing, need not often dismantling and reliable and stable support, will have very wide market prospects.
Summary of the invention:Purpose of the present invention is providing a kind of long-lived centre frame for roll grinder, this centre frame does not does not wear and tear, need not often change tray, and realizes different-diameter specification roll is carried out reliable and stable support.
Formation of the present invention: a kind of static-pressure central frame of supporting roller floating type, by housing, static pressure tray up and down, supporting roller up and down, drive unit, limiting plate up and down, oil inlet pipe and oil extraction pipeline form up and down, it is characterized in that: all have static-pressure oil chamber on upper static pressure tray and the lower static pressure tray bearing-surface, upper support roller and lower support roller are installed in respectively on the static-pressure oil chamber bearing-surface of static pressure tray and lower static pressure tray, workpiece is placed on upper support roller and the lower support roller and supports, at upper static pressure tray afterbody and housing screw rod driving device is installed, the skewback below lower static pressure tray and housing are installed the skewback drive unit.
Pressure oil forms hydrostatic effects after entering static-pressure oil chamber, makes the supporting surface of upper support roller and lower support roller and upper static pressure tray and lower static pressure tray that certain floatation volume be arranged.
When workpiece rotating, can drive the upper support roller and the lower support roller rotates simultaneously.
Upper support roller and lower support roller are by upper limit plate and lower limiting board constraint with mounting hole.
Adjust the displacement of upper support roller and lower support roller according to the diameter of workpiece.
Upper static pressure tray is directly to drive by screw rod driving device, and lower static pressure tray is to drive by skewback drive unit pulling skewback wherein.
Compared with prior art, the present invention has following features: when the present invention combines static-pressure central frame and slip centre frame advantage, do not reduce the reliability of its support.For common static-pressure central frame, the present invention also can realize the support to the differential roller footpath in the situation that need not change the static pressure tray; For common slip centre frame, the present invention is floated support by static pressure, and tray need not often be changed in wearing and tearing.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is static-pressure bracket watt oil recess structure figure up and down.
Among the figure 1, housing, 2, lower static pressure tray, 3, lower oil inlet pipe, 4, lower support roller, 5, workpiece, 6, the upper support roller, 7, upper oil inlet pipe, 8, upper static pressure tray, 9, screw rod driving device, 10, skewback drive unit, 11, the upper limit plate, 12, lower limiting board, 13, oil extraction pipeline, 14, oil inlet pipe, 15, the oil return annular groove, 16, static-pressure oil chamber, 17, fuel feed hole, 18, oil drain out.
The specific embodiment:
As Figure 1-3, formation of the present invention: consisted of by housing 1, upper static pressure tray 8, upper support roller 6, upper oil inlet pipe 7, upper limit plate 11, screw rod driving device 9, lower static pressure tray 2, lower support roller 4, lower oil inlet pipe 3, lower limiting board 12, skewback drive unit 10 and oil extraction pipeline 13.
Be equipped with static-pressure oil chamber 16 on upper static pressure tray 8 and lower static pressure tray 2 bearing-surfaces, upper support roller 6 is installed on the static pressure tray 8, and lower support roller 4 is installed on the lower static pressure tray 2, and workpiece 5 is placed on upper support roller 6 and the lower support roller 4 and supports.
Pressure oil enters static-pressure oil chamber 16 and forms hydrostatic effects, makes upper support roller 6 and upper static pressure tray 8 supporting surfaces that certain floatation volume be arranged, and makes lower support roller 4 and lower static pressure tray 2 supporting surfaces that certain floatation volume be arranged;
Upper support roller 6 is by upper limit plate 11 constraint with mounting hole, and lower support roller 4 is by lower limiting board 12 constraints, prevent supporting roller when not having Work-sheet pressing from the supporting surface of static pressure tray and lower static pressure tray come off;
When workpiece 5 rotation, can drive upper support roller 6 and lower support roller 4 and rotate simultaneously;
Can adjust according to the diameter of workpiece 5 displacement of upper support roller 6 and lower support roller 4;
Upper static pressure tray 8 is directly to drive by screw rod driving device 9, and lower static pressure tray 2 is to drive by skewback drive unit 10 pullings skewback wherein.
