Abstract
The utility model relates to a lathe support component, concretely relates to gantry machine tools's circular muscle formula crossbeam, including the outer wall of square, the outer wall inscription has a round muscle, and circle muscle and outer wall are connected as an organic wholely through four bonding points of tangent department, all is equipped with the venthole on outer wall and the round muscle, and the gusset is equipped with at the outer wall both ends, this crossbeam reasonable in design, and crossbeam distortion's problem elimination, in the course of working, the stability of crossbeam obtains the machining precision of obvious promotion, assurance lathe.
Description
Technical field
The utility model relates to a kind of lathe support component, is specifically related to a kind of circular muscle formula crossbeam 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.The large multiple stiffness of crossbeam of prior art is not enough, and particularly when main spindle box runs to crossbeam medium position, the easy torsional deformation of crossbeam, and castings material slightly difference, torsional deformation amount is just different, affects machining accuracy.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the circular muscle formula crossbeam providing a kind of Longmen machine tool, eliminates the torsional deformation of crossbeam, ensures the machining accuracy of lathe.
The circular muscle formula crossbeam of Longmen machine tool described in the utility model, comprises foursquare outer wall, is connected to round muscle in outer wall, and circle muscle and outer wall are connected as one by the four combinations point at tangent place, and outer wall and circle muscle are equipped with venthole, and gusset is equipped with at outer wall two ends.
The carrying of crossbeam and machining load eliminate torsional deformation by the version of outer wall and inscribed circle muscle, not by the impact of castings material, ensure that 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, the reinforcement square crossing on gusset.
Preferably, the venthole on outer wall is circular port, and the venthole on circle muscle is strip hole, uniform according to structure, convenient processing.
Preferably, outer wall is casting integrated structure with circle muscle.
Preferably, outer wall is welded as a whole with circle muscle.
The beneficial effect that the utility model is compared with prior art had is:
The circular muscle formula beam design of Longmen machine tool is reasonable, and the problem of crossbeam torsional deformation is eliminated, and in process, the stability of crossbeam is significantly improved, and ensures the machining accuracy of lathe.
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, gusset; 2, outer wall; 3, venthole; 4, binding site; 5, muscle is justified; 6, reinforcement.
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 circular muscle formula crossbeam of Longmen machine tool comprises foursquare outer wall 2, is connected to round muscle 5 in outer wall 2, and circle muscle 5 is connected as one by the four combinations point 4 at tangent place with outer wall 2, outer wall 2 and circle muscle 5 are equipped with venthole 3, and gusset 1 is equipped with at outer wall 2 two ends.
Reinforcement 6 on gusset 1 is in groined type square crossing.
Venthole 3 on outer wall 2 is circular port, and the venthole 3 on circle muscle 5 is strip hole.
Outer wall 2 can think casting integrated structure with circle muscle 5, also can be welded as a whole.
The carrying of crossbeam and machining load eliminate torsional deformation by the version of outer wall 2 and inscribed circle muscle 5, and avoid the impact of castings material, in process, stability and the machining accuracy of crossbeam obviously promote; Venthole 3 both can be ventilated, and served again the effect of loss of weight, sand removal.
