Abstract
The utility model discloses a sealing device used for an electric spark molding machine tool oil trough and a work table, belonging to the machine tool design technical field, and provides a sealing device with good sealing for electric spark molding machine tool oil trough and the work table. The utility model is characterized in that the work table adopts the structure of that dual-sealing troughs are embedded into the oil-resistance foam rubber; the oil trough in the middle of the dual-sealing troughs is fixed on the work table by a tightening screw. By using the features of the oil-resistance foam rubber of good elasticity, good molding through the die and the optionally design of the elastic force, the sealing problem is solved. The utility model has the advantages of simple whole structure, good sealing effect, and low processing precision of needed assembly parts and improves the quality of the products and the assembly efficiency of the whole machine to some extent.
Description
Technical field
The utility model discloses a kind of sealing device that is used for EDM shaping machine oil groove and workbench, belong to the Machine Tool design technical field.
Background technology
The sealing of EDM shaping machine oil groove and workbench is owing to need the big (0.5m of the area of sealing
2More than), adopt the conventional seals backing structure to be difficult to reach seal request, difficulty is that the flatness of sealing surface is had relatively high expectations processing difficulties.Simultaneously, make oil groove loosening in the transporting and hoisting process easily, sealing place is ftractureed easily, causes sealing surface place oil impregnate even leakage of oil.In addition, the working media one industrial kerosene permeability that EDM shaping machine uses is very strong, has caused very big difficulty to sealing.
Summary of the invention
The utility model provides a kind of EDM shaping machine oil groove of good airproof performance and the sealing device of workbench at the deficiency of prior art.
Technical characterictic of the present utility model is that workbench adopts the double density sealing groove to embed the structure of oil resistant foam rubber, by housing screw oil groove is fixed on the workbench in the middle of the double density sealing groove.Utilize arbitrarily design characteristic of the good springiness of oil resistant foam rubber,, elasticity strength good, solved sealing problem by die forming.
Concrete structure of the present utility model: the sealing device of a kind of EDM shaping machine oil groove and workbench, comprise workbench, oil groove, it is characterized in that the groove that has at least twice annular enclosed on the workbench, groove is embedded in the oil resistant foam rubber, by housing screw oil groove and stationary table is integral in the middle of two grooves.
The overall structure characteristics are simple, good sealing effect, required build-up member machining accuracy are low, improved product quality and final assembly efficient to a certain extent.Even flat seal place flatness is poor on the workbench, rely on the strain of himself, make two faying faces of sealing closely be close to all the time, reach the effect of sealing.
Description of drawings
The specific embodiment
Embodiment:
The sealing device of a kind of EDM shaping machine oil groove and workbench, comprise workbench 4, oil groove 3, it is characterized in that having the annular enclosed groove of twice on the workbench 4 at least, groove is fixed into one by housing screw 1 with oil groove 3 and workbench 4 in the middle of being embedded in oil resistant foam rubber 2, two grooves.
Working table structure such as Fig. 1, Fig. 2, the assembling back is as Fig. 3; Milling Process twice annular seal groove on workbench 4 sealing planes at first, the oil resistant foam rubber 2 of packing into compresses oil groove 3 and workbench 4 by housing screw 1.
