Description
Technical field
The present invention relates to a kind of gear-hobbing machine, particularly a kind of layout structure of gear-hobbing machine.
Background technology
The machine tool main body structure of tradition gear-hobbing machine comprises: lathe bed, big column, workbench and rear column; Its layout type is: big column, workbench and rear column are arranged in parallel at lathe bed successively, and column, workbench and rear column is centered close on the lathe bed axis greatly.In this layout structure, big column makes independently with rear column and is connected with lathe bed, does not have annexation between big column and the rear column, and it is bigger that the volume of therefore big column and rear column must be made, to guarantee its rigidity.Interval broad between simultaneously big column and the rear column, complete machine takes up room bigger, and layout is looser.And big column and rear column apart arrangement, its operation interval is bigger, is difficult for sealing, and chip removal structural design difficulty is very big fast, and layout structure is not suitable for dry type smear metal processing.
Therefore need that gear-hobbing machine layout mechanism improves in the prior art,, make layout compact more, reduce the lathe volume, and make it can be applicable to dry type smear metal gear-hobbing machine to improve its rigidity.
Summary of the invention
In view of this, the purpose of this invention is to provide the high rigidity DRY CUTTING of a kind of compact gear-hobbing machine layout structure, it has the advantage of rigidity height, compact conformation, and lathe takes up room little, and layout structure is applicable to dry type smear metal gear-hobbing machine.
The high rigidity DRY CUTTING of a kind of compact of the present invention gear-hobbing machine layout structure; Comprise lathe bed, big column, workbench and rear column; Said big column is arranged in the vertical limit portion of lathe bed, and said rear column is arranged in the widthwise edge portion of lathe bed, the end of big column and the rear column formation L type structure of joining; The lathe bed middle part also is provided with the partitions that is arranged in parallel with rear column; Said partitions is joined with big column and is formed T type structure, and the zone that said big column, rear column and partitions surround is a cutting region, and said workbench is arranged on the lathe bed in the cutting region.
Further, the position that said big column is relative with cutting region is provided with the maintenance window;
Further, the relative position of said rear column and cutting region is provided with the input and output material window;
Further; Comprise also being positioned at cutting region and being fixed on the smear metal protective cover on workbench, big column, rear column and the partitions wall that smear metal protective cover and big column, sidepiece and the smear metal protective cover bottom relative with workbench that rear column is relative with partitions are formed by the swash plate that tilts to the lathe bed below;
Further, the inclined-plane of said composition protective cover to the angle of inclination of oblique below in 45 °～90 ° scopes;
Further, also be provided with the compressed air shower nozzle on the said smear metal protective cover;
Further, said smear metal protective cover is processed by stainless steel material.
Beneficial effect of the present invention: the high rigidity DRY CUTTING of a kind of compact of the present invention gear-hobbing machine layout structure; Be fixedly connected between its big column and the rear column, good rigidly helps reducing the volume of big column and rear column; And big column becomes the L type to arrange with rear column; Compact conformation, the cutting region space hold is less, therefore adopts the gear-hobbing machine overall volume of this layout structure less.Simultaneously because cutting region takes up space little; Be convenient to sealing; The cutting region inwall is provided with the smear metal protective cover, and the smear metal protective cover can prevent that high-temperature iron scurf from contacting with machine tool main body, also can cutting region be discharged in smear metal fast, thereby the heat energy that makes iron filings pass to machine tool main body reduces; Can reduce the lathe temperature, guarantee machine tool accuracy; Therefore this layout structure is applicable to dry type smear metal gear-hobbing machine.
