Abstract
The utility model discloses a crossbeam in a cavity type structure, and belongs to the field of mechanical crossbeams. The crossbeam in the cavity type structure comprises a plurality of cavity units which contact with one another in a fit mode. Each cavity unit is a hollow cube or a hollow cuboid, and a through hole is formed in each of the six cavity walls of each cavity unit. Due to the cavity type structure, compared with a frame type structure and a plate-rib mechanism in the prior art, the crossbeam in the cavity type structure is higher in rigidity, more stable in structure and not prone to deformation in the using process, and work precision of a machine tool is guaranteed; and compared with a solid crossbeam, the crossbeam in the cavity type structure is lighter in weight and convenient to move.
Description
Technical field
The utility model relates to a kind of crossbeam of cavity structure, belongs to mechanical crossbeam field.
Background technology
In the prior art, the crossbeam that is used on the lathe generally all adopts frame structure, plate muscle structure or solid construction.Although adopt frame structure and plate muscle structure can alleviate the weight of crossbeam, a little less than its structural rigidity, be out of shape easily, can affect the precision of lathe after use a period of time; Although and the crossbeam rigidity of solid construction is strong, Stability Analysis of Structures, weight is heavier, and it is very inconvenient that the lathe transition are moved, inapplicable on heavy duty machine tools.
In view of this, the inventor studies this, develops specially a kind of crossbeam of cavity structure, and this case produces thus.
The utility model content
The purpose of this utility model provides that a kind of rigidity is strong, Stability Analysis of Structures and on-deformable cavity structure crossbeam.
To achieve these goals, solution of the present utility model is:
A kind of crossbeam of cavity structure, described crossbeam comprise the cavate unit that several are bonded to each other, and described cavate unit is square or the cuboid of hollow, have all dug a through hole on six chamber walls of cavate unit.
Through hole on the wall of chamber can be various shape, and such as square, rectangle, ellipse or circular etc. wherein one or more combinations, the size of through hole is decided according to the supporting power of crossbeam.
The volume of cavate unit determines by the supporting power of crossbeam, and when the supporting power of crossbeam was larger, the cavate unit volume was less, and namely in the unit volume of crossbeam, cavate unit number increases; When the supporting power of crossbeam hour, the cavate unit volume more greatly, namely in the unit volume of crossbeam, cavate unit number reduces.
As preferably, be positioned at its chamber wall thickness of cavate unit of crossbeam outer surface greater than other chamber walls of crossbeam inside.
The crossbeam of cavate described in the utility model mechanism, can be applied on the multiple mechanical device, such as planer-type milling machine etc., adopt the crossbeam of above-mentioned cavity structure, compare with plate muscle mechanism with frame structure of the prior art, rigidity is stronger, structure is more stable and use procedure in not yielding, guarantee the operating accuracy of lathe, compare with solid beam, weight is lighter, is convenient to move.
Below in conjunction with drawings and the specific embodiments the utility model is done and to be described in further detail.
Description of drawings
Fig. 1 is the cavity structure crossbeam stereogram of present embodiment;
Fig. 2 is the cavate unit three-dimensional figure of present embodiment.
The specific embodiment
As depicted in figs. 1 and 2, a kind of crossbeam of cavity structure, described crossbeam comprise the cavate unit 1 that several are bonded to each other, and described cavate unit 1 is square or the cuboid of hollow, have all dug a through hole 111 on six chamber walls 11 of cavate unit 1.
Through hole 111 on the chamber wall 11 can be various shape, and such as square, rectangle, ellipse or circular etc. wherein one or more combinations, the size of through hole 111 is decided according to the supporting power of crossbeam.
The volume of cavate unit 1 determines by the supporting power of crossbeam, and when the supporting power of crossbeam was larger, cavate unit 1 volume was less, and namely in the unit volume of crossbeam, cavate unit 1 number increases; When the supporting power of crossbeam hour, cavate unit 1 volume more greatly, namely in the unit volume of crossbeam, cavate unit 1 number reduces.
In the present embodiment, crossbeam laterally is comprised of 2*2 cavate unit 1; Crossbeam vertically is comprised of 9 cavate unit 1.
Cavate unit 1 chamber wall, 11 its thickness of crossbeam outer surface are greater than other chamber walls 11 in the crossbeam, and according to the actual moulding of crossbeam, cavate unit 1 through hole, 111 sizes of crossbeam outer surface also can correspondingly be adjusted sometimes.
Each outer surface of crossbeam also can arrange all parts on the basis of cavate unit 1 chamber wall 11, such as guide rail groove etc.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
Claims (4)
