Abstract
The utility model relates to a kind of lathe support component, the double walled crossbeam of concrete a kind of Longmen machine tool, comprise the inwall of outer wall and rectangle, inwall four limit is cast into one by lateral connection muscle and longitudinal dowel and outer wall, and outer wall, inwall, lateral connection muscle and longitudinal dowel are equipped with venthole, outer wall two ends are provided with end plate, this beam design is reasonable, and crossbeam elastic deformation amount is diminished, in process, the stability of crossbeam is significantly improved, and ensures the stable of machine tool accuracy.
Description
Technical field
The utility model relates to a kind of lathe support component, the double walled crossbeam of concrete a kind of Longmen machine tool.
Background technology
In currently available technology, the main shaft of Longmen machine tool is arranged on the gantry structure that two root posts and cross-arm form in stand column and beam, the movement in vertical direction of the plane that gantry is formed along its column, crossbeam constitutes the X-axis of lathe, main shaft moves along the length direction of crossbeam and constitutes the Y-axis of lathe, and main shaft self vertically moves and constitutes the Z axis of lathe; Crossbeam directly carries total weight and the machining load of main shaft, and the rigidity of crossbeam decides rigidity and the machining accuracy of whole lathe; Crossbeam is laterally carried on a shoulder pole and is put in column simultaneously, is in the state being beneficial to distortion, and therefore the structure of crossbeam is the key keeping machine tool accuracy.Crossbeam precision in the application of reality of prior art not easily ensures, namely uses reversible deformation processing, can not ensure stable accuracy, affect crudy.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the double walled crossbeam providing a kind of Longmen machine tool, ensures that machine finish is stablized.
The double walled crossbeam of Longmen machine tool described in the utility model, comprise the inwall of outer wall and rectangle, inwall four limit is cast into one by lateral connection muscle and longitudinal dowel and outer wall, and outer wall, inwall, lateral connection muscle and longitudinal dowel are equipped with venthole, and outer wall two ends are provided with end plate.
The version of the inwall that outer wall is connected with dowel improves the rigidity of crossbeam, and the carrying of crossbeam and machining load reduce the elastic deformation that crossbeam produces, and also reduces the numerical value of reversible deformation processing simultaneously, ensure that integral rigidity and the machining accuracy of lathe; The setting of venthole both can be ventilated, sand removal, served again the effect of loss of weight.
Preferably, venthole is rectangular opening, uniform according to structure, convenient processing.
The beneficial effect that the utility model is compared with prior art had is:
The double walled beam design of Longmen machine tool is reasonable, and crossbeam elastic deformation amount is diminished, and in process, the stability of crossbeam is significantly improved, and ensures the stable of machine tool accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross section view of the present utility model.
In figure: 1, outer wall; 2, venthole; 3, end plate; 4, inwall; 5, lateral connection muscle; 6, longitudinal dowel.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, the double walled crossbeam of Longmen machine tool comprises the inwall 4 of outer wall 1 and rectangle, inwall 4 four limit is cast into one by lateral connection muscle 5 and longitudinal dowel 6 with outer wall 1 when casting, outer wall 1, inwall 4, lateral connection muscle 5 and longitudinal dowel 6 are equipped with venthole 2, and outer wall 1 two ends are provided with end plate 3.
Venthole 2 is rectangular opening.
The version of the inwall 4 that the carrying of crossbeam is connected by outer wall 1 and dowel with machining load makes crossbeam elastic deformation amount reduce, and in process, stability and the machining accuracy of crossbeam obviously promote; Venthole 2 both can be ventilated, sand removal, served again the effect of loss of weight, sand removal.
