Abstract
A kind of static-pressure central frame of supporting roller floating type.This centre frame is made up of housing (1), static pressure tray (8,2), supporting roller (6,4), drive unit (9,10), limiting plate (11,12), in-line (7,3) and drain line (13), it is characterized in that: upper and lower two static pressure trays (8,2) bearing-surface all has static-pressure oil chamber (16), upper and lower supporting roller (6,4) is arranged on the static-pressure oil chamber bearing-surface of upper and lower static pressure tray (8,2) respectively, and workpiece (5) is placed in upper and lower supporting roller (6,4) and supports.When workpiece rotates, upper and lower supporting roller (6,4) can be driven to rotate.Because upper and lower supporting roller (6,4) is supported by static pressure, therefore have frictional force little, vibrate little and long-lived feature.
Description
Technical field
The present invention relates to the support of workpiece, especially the 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 static-pressure central frame and slip centre frame two kinds.The static pressure supporting surface of static-pressure central frame is circular arc, and a static pressure supporting surface can only match and could form hydrostatic effects with a kind of roller footpath, therefore has the specification of how many roll diameter of roller, just needs to configure the different static pressure tray of how many kinds of.Slip centre frame is directly contacted with supporting surface by roll, and vibration is large, and wearing and tearing are comparatively serious, therefore need often to change tray, thus cause the waste of material.Therefore, how to design a set of centre frame, realize it without wearing and tearing, need not often dismantling and reliable and stable support, will there are very wide market prospects.
summary of the invention:object 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, often need not change tray, and realizes carrying out reliable and stable support to different-diameter specification roll.
Formation of the present invention: a kind of static-pressure central frame of supporting roller floating type, by housing, upper and lower static pressure tray, upper and lower supporting roller, drive unit, upper and lower limiting plate, upper and lower oil inlet pipe and drain line composition, it is characterized in that: upper static pressure tray and lower static pressure tray bearing-surface all have static-pressure oil chamber, upper supporting roller and lower support roller are arranged on the static-pressure oil chamber bearing-surface of static pressure tray and lower static pressure tray respectively, workpiece is placed on supporting roller and lower support roller and supports, upper static pressure tray afterbody and housing install screw rod driving device, skewback below lower static pressure tray and housing install skewback drive unit.
Pressure oil forms hydrostatic effects after entering static-pressure oil chamber, makes the supporting surface of supporting roller and lower support roller and upper static pressure tray and lower static pressure tray have certain floatation volume.
When workpiece rotates, supporting roller and lower support roller can be driven to rotate simultaneously.
Upper supporting roller and lower support roller retrain by with the upper limit plate of mounting hole and lower limiting board.
The displacement of upper supporting roller and lower support roller is adjusted according to the diameter of workpiece.
Upper static pressure tray carrys out Direct driver by screw rod driving device, and lower static pressure tray pulls skewback wherein to drive by skewback drive unit.
Compared with prior art, the present invention has following features: while present invention incorporates static-pressure central frame and slip centre frame advantage, does not reduce the reliability that it supports.For common static-pressure central frame, the present invention also can realize the support to differential roller footpath when changing static pressure tray; For common slip centre frame, the present invention floats support by static pressure, and wearing and tearing, often need not change tray.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is upper and lower static-pressure bracket watt oil recess structure figure.
In figure 1, housing, 2, lower static pressure tray, 3, lower oil inlet pipe, 4, lower support roller, 5, workpiece, 6, upper supporting roller, 7, upper oil inlet pipe, 8, upper static pressure tray, 9, screw rod driving device, 10, skewback drive unit, 11, upper limit plate, 12, lower limiting board, 13, drain line, 14, oil inlet pipe, 15, oil return annular groove, 16, static-pressure oil chamber, 17, fuel feed hole, 18, oil drain out.
detailed description of the invention:
As Figure 1-3, formation of the present invention: be made up of housing 1, upper static pressure tray 8, upper supporting 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 drain line 13.
Upper static pressure tray 8 and lower static pressure tray 2 bearing-surface are equipped with static-pressure oil chamber 16, and upper supporting roller 6 is arranged on static pressure tray 8, and lower support roller 4 is arranged on lower static pressure tray 2, and workpiece 5 is placed on supporting roller 6 and lower support roller 4 and supports.
Pressure oil enters static-pressure oil chamber 16 and forms hydrostatic effects, makes supporting roller 6 and upper static pressure tray 8 supporting surface have certain floatation volume, makes lower support roller 4 and lower static pressure tray 2 supporting surface have certain floatation volume;
Upper supporting roller 6 is retrained by the upper limit plate 11 with mounting hole, and lower support roller 4 is retrained by lower limiting board 12, prevent supporting roller when there is no Work-sheet pressing from the supporting surface of static pressure tray and lower static pressure tray come off;
When workpiece 5 rotates, supporting roller 6 and lower support roller 4 can be driven to rotate simultaneously;
The displacement of upper supporting roller 6 and lower support roller 4 can be adjusted according to the diameter of workpiece 5;
Upper static pressure tray 8 carrys out Direct driver by screw rod driving device 9, and lower static pressure tray 2 pulls skewback wherein to drive by skewback drive unit 10.
