Abstract
The invention discloses a hydraulic automatic gap-eliminating panel mechanism. After a panel is worn, by adjusting the oil pressure of hydraulic oil in an oil cavity, a piston can apply appropriate pressure to the panel to ensure that a part of the panel, which is opposite to a guide rail, is integrally subjected to bending deformation towards the guide rail and a gap between the guide rail and a sliding plate is kept unchanged, so that the accuracy of a machine tool can be ensured; and the size of the oil pressure is convenient to adjust and controllable, so that the maintenance workload of the panel mechanism can be greatly reduced, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of machine tool guideway parts, particularly a kind of slide gib.
Background technology
Machine tool guideway panel commonly used is oblique panel, and tiltedly the gradient of panel is 1:100, and tiltedly panel is embedded between the pressing plate and guide rail of slide plate, tiltedly two faces of panel respectively with the pressing plate and the guide rail even contact of slide plate, reduce the friction between guide rail and pressing plate through panel.After the panel wearing and tearing, the gap between slide block and guide rail can be strengthened, and this situation can reduce the machining accuracy of lathe, and aggravates the wearing and tearing of slide block and guide rail easily; Therefore after the panel wearing and tearing, need repair a die, and regulate the embedded location of panel, thereby the gap between panel and guide rail is remained unchanged panel.But this panel; Its adjustment work that repairs a die is comparatively loaded down with trivial details, and tiltedly panel has tapering, its uneven thickness; The stress distribution of panel is uneven after processing; In adjustment, compress or panel is stressed under the lathe duty occurs bending and deformation easily, thereby the gap between slide block and guide rail is changed, influence machine finish.And because that lathe when work slide plate moves back and forth is frequent, need regularly the adjustment that repairs a die of oblique panel, maintenance work is frequent, so can reduce lathe production efficiency.
Therefore need the oblique panel of lathe of the prior art to improve, to solve the problem that it exists.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of hydraulic pressure automatic anti-backlash panel mechanism, it has automatic compensation function after the panel wearing and tearing, remains unchanged to guarantee the gap between guide rail and slide plate, thereby guarantees machine tool accuracy; And can reduce maintenance workload to panel, enhance productivity.
Hydraulic pressure automatic anti-backlash panel of the present invention mechanism; Comprise the pressing plate that is arranged on the lathe slide plate and be arranged at the panel on the pressing plate; Pressing plate longitudinal middle part both sides are respectively and slide plate opposing first regions and the second area relative with machine tool guideway; The first area of panel and pressing plate is fixedly connected; The second area of panel and pressing plate freely contacts, and the second area of pressing plate longitudinally is set side by side with and also is provided with the oil supply gallery that is communicated with oil pocket on several oil pockets and the pressing plate, is provided with the piston of exerting pressure to panel in the oil pocket.
Further, the face that cooperates with machine tool guideway on the panel is provided with the wear-resistant plastic filler strip;
Further, said panel is that thickness is the steel bar of 10mm.
Beneficial effect of the present invention: hydraulic pressure automatic anti-backlash panel of the present invention mechanism; After the panel wearing and tearing; Through regulating the oil pressure of hydraulic oil in the oil pocket; Piston just can apply suitable pressure to panel and make the whole flexural deformation that produces to the guide rail direction of the panel part relative with guide rail, the gap between guide rail and slide plate is remained unchanged, thereby can guarantee machine tool accuracy; And the oil pressure size adjustment is convenient controlled, thereby the maintenance workload of reduction panel mechanism that can be very big is enhanced productivity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is the transverse sectional view of hydraulic pressure automatic anti-backlash panel of the present invention mechanism;
Fig. 2 is the partial enlarged view of I portion among Fig. 1;

The specific embodiment
Fig. 1 is the transverse sectional view of hydraulic pressure automatic anti-backlash panel of the present invention mechanism; Fig. 2 is the partial enlarged view of I portion among Fig. 1; Fig. 3 is along the broken section zoomed-in view of A-A among Fig. 1.
As shown in the figure; Present embodiment hydraulic pressure automatic anti-backlash panel mechanism; Comprise the pressing plate 2 that is arranged on the lathe slide plate 1 and be arranged at the panel 3 on the pressing plate 2; Pressing plate 2 longitudinal middle part both sides are respectively and slide plate 1 opposing first regions and the second area relative with machine tool guideway 4, and panel 3 is fixedly connected with the first area of pressing plate 2, and panel 3 freely contacts with the second area of pressing plate 2; The second area of pressing plate 2 longitudinally is set side by side with and also is provided with the oil supply gallery 2b that is communicated with oil pocket 2a on several oil pockets 2a and the pressing plate 2, is provided with the piston 5 of exerting pressure to panel 3 in the oil pocket.
Panel 3 is connected through bolt with the first area of pressing plate 2 in this enforcement, also connects easy accessibility between pressing plate 2 and the slide plate 1 through bolt; Certainly in different embodiments, also can adopt other forms of connector to connect.Oil pocket 2a in the present embodiment is 5, is provided with 5 and can satisfies panel to the distortion of the bending of rail-sides evenly; Certainly in different embodiments, the quantity of oil pocket can specifically be adjusted as required, and oil pocket quantity is many more, can guarantee the deformation uniformity of panel more, but cost of manufacture is also higher simultaneously.
Hydraulic pressure automatic anti-backlash panel of the present invention mechanism; After the panel wearing and tearing; Through regulating the oil pressure of hydraulic oil in the oil pocket; Piston just can apply suitable pressure to panel and make the whole flexural deformation that produces to the guide rail direction of the panel part relative with guide rail, the gap between guide rail and slide plate is remained unchanged, thereby can guarantee machine tool accuracy; And the oil pressure size adjustment is convenient controlled, thereby the maintenance workload of reduction panel mechanism that can be very big is enhanced productivity.
As the improvement to this embodiment, the face that cooperates with machine tool guideway on the panel 3 is provided with wear-resistant plastic filler strip 6, and this structure can prolong the service life of panel 2.
In the present embodiment, said panel 2 is the steel bar of 10mm for thickness, and integration capabilities such as its rigidity and deformation performance are better.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
