Abstract
The utility model discloses a cross beam structure of an extra-large gate width gantry processing center. The cross beam structure comprises a cross beam body. The cross beam body is in a cuboid box body structure, a plurality of bars are evenly arranged in a cross beam box body, two lower-part supports are arranged at the middle position of a bottom plate of the cross beam box body, and top positions of two ends of the cross beam are respectively provided with an adjusting bolt fixing seat. An adjusting bolt is fixed on each adjusting bolt fixing seat, an inclined pull rod surrounds a fixing bolt at one end of the cross beam and penetrates through the two lower-part supports of the cross beam, and the two pull rods are in symmetrical structures. The cross beam structure of the extra-large gate width gantry processing center is high-efficiency and reliable, saves cost, can improve rigidity of the cross beam and resist droop under the premise of not increasing weight of the cross beam, and guarantees processing accuracy and stability of a machine tool.
Description
Technical field
The utility model relates to a kind of beam structure of super large gate-width gantry machining center.
Background technology
In recent years, greatly develop in country under the influence of equipment manufacture policy, industrial technology has obtained swift and violent development, and numerical control machining center has become the process equipment that the most widely uses in recent years.Characteristics such as its high efficiency, high accuracy, high stability, ease for operation make is bringing into play the effect of not replacing in its Modern Production.Along with the development of infant industries such as automobile making, aircraft, pleasure boat, automated arm, wind energy, solar energy industry, process equipment is had higher requirement.The super large gate-width gantry machining center of big cutting output, big stroke, multiaspect processing arises at the historic moment.
In the numerical control machining center of super large gantry, crossbeam is the most key parts, has directly determined the overall precision and the performance of lathe.Because super large gate-width gantry machining center crossbeam is all very long, how when weight is constant, to strengthen the crossbeam rigidity, reduce its deadweight sag of chain and become a problem demanding prompt solution.
For guaranteeing the crossbeam rigidity, the opposing beam deformation must increase crossbeam outer wall thickness and rib quantity in the tradition beam structure, and this method can cause crossbeam weight to increase, and bead structures is complicated, is not easy to welding, increases the lathe cost, and poor effect.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of beam structure of super large gate-width gantry machining center is provided; Its high efficient and reliable, practice thrift cost and under the prerequisite that does not increase crossbeam weight, can improve the crossbeam rigidity simultaneously and resist saggingly, can guarantee machine finish and stability.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of beam structure of super large gate-width gantry machining center; Comprise cross-beam body; Said cross-beam body is the cuboid box body structure, evenly is provided with the multiple tracks rib in the crossbeam casing, and said crossbeam box bottom centre position is provided with two lower seats; The two ends tip position of crossbeam is respectively arranged with an adjustment bolt seat; Be fixed with an adjustment bolt respectively on each adjustment bolt seat, walk around the set bolt of crossbeam one end and be provided with an oblique pull bar, amount to two pull bars through the crossbeam lower seat.
Two pull bars are symmetrical structure.
The utlity model has following beneficial effect:
1, the utility model adopts Tiebar structure, and crossbeam two terminal screws adjustment pull bar capable of using is tightened dynamics, reduces the sagging effect of crossbeam deadweight thereby reach.
2, owing to the effect of pull bar, the crossbeam wall thickness reduces, and rib quantity reduces and simple shape is made easily, and welding is compared the weight that has reduced crossbeam significantly with old beam design and reduced the lathe cost easily.
The utility model high efficient and reliable, practice thrift cost and under the prerequisite that does not increase crossbeam weight, can improve the crossbeam rigidity simultaneously and resist saggingly, can guarantee machine finish and stability.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of beam structure of super large gate-width gantry machining center, comprises cross-beam body 1; Said cross-beam body is the cuboid box body structure; Evenly be provided with multiple tracks rib 2 in the crossbeam casing, said crossbeam box bottom centre position is provided with two lower seats 3, and the two ends tip position of crossbeam is respectively arranged with an adjustment bolt seat 4; Be fixed with an adjustment bolt 5 respectively on each adjustment bolt seat; Walk around the set bolt of crossbeam one end and be provided with an oblique pull bar 6 through the crossbeam lower seat, amount to two pull bars, two pull bars are symmetrical structure.
The utility model adopts Tiebar structure, and crossbeam two terminal screws adjustment pull bar capable of using is tightened dynamics, reduces the sagging effect of crossbeam deadweight thereby reach.Because the effect of pull bar, the crossbeam wall thickness reduces, and rib quantity reduces and simple shape is made easily, and welding is compared the weight that has reduced crossbeam significantly with old beam design and reduced the lathe cost easily.
The utility model high efficient and reliable, practice thrift cost and under the prerequisite that does not increase crossbeam weight, can improve the crossbeam rigidity simultaneously and resist saggingly, can guarantee machine finish and stability.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (2)
1. the beam structure of a super large gate-width gantry machining center; It is characterized in that: comprise cross-beam body; Said cross-beam body is the cuboid box body structure, evenly is provided with the multiple tracks rib in the crossbeam casing, and said crossbeam box bottom centre position is provided with two lower seats; The two ends tip position of crossbeam is respectively arranged with an adjustment bolt seat; Be fixed with an adjustment bolt respectively on each adjustment bolt seat, walk around the set bolt of crossbeam one end and be provided with an oblique pull bar, amount to two pull bars through the crossbeam lower seat.
