Abstract
The utility model discloses a kind of crossbeam of Longmen machine tool, including outer wall, outer wall is transversely equipped with rectangular-ambulatory-plane partition, four sides of the rectangular-ambulatory-plane partition with outer wall is vertical is fixedly connected, the quantity of the rectangular-ambulatory-plane partition is no less than one；The outer wall both ends are equipped with end plate, and the end plate is connect with rectangular-ambulatory-plane partition by dowel, and the outer wall is equipped with the first venthole, and the end plate and rectangular-ambulatory-plane partition are equipped with the second venthole.Rationally, rectangular-ambulatory-plane partition and dowel combination can promote bending resistance and torsional rigidity simultaneously, so that the problem of crossbeam torsional deformation is eliminated, stability is significantly improved, and guarantees the machining accuracy of lathe for the crossbeam design of the utility model.
Description
Technical field
The utility model relates to a kind of lathe support members, and in particular to a kind of crossbeam of Longmen machine tool.
Background technique
The main shaft of Longmen machine tool is mounted on two root posts and cross-arm at gantry that stand column and beam is constituted in currently available technology
In structure, gantry constitutes the X-axis of lathe along the movement in vertical direction for the plane that its column, crossbeam are formed, and main shaft is along crossbeam
Length direction movement constitutes the Y-axis of lathe, and main shaft itself, which is movable in a vertical direction, constitutes the Z axis of lathe；Crossbeam is directly held
The total weight and machining load of main shaft are carried, the rigidity of crossbeam decides the rigidity and machining accuracy of entire lathe；Crossbeam simultaneously
Laterally load is put in column, and in the state for being conducive to deformation, therefore the structure of crossbeam is to maintain the key of machine tool accuracy.The prior art
The big multiple stiffness of crossbeam it is insufficient, crossbeam is easy torsional deformation, and castings material slight difference, torsional deformation amount just difference, shadow
Ring machining accuracy.
Utility model content
Purpose of utility model: the utility model aim is to provide a kind of crossbeam of Longmen machine tool, can eliminate the torsion of crossbeam
Song deformation, guarantees the machining accuracy of lathe.
Technical solution: the crossbeam of the utility model Longmen machine tool, including outer wall, outer wall are transversely equipped with rectangular-ambulatory-plane partition,
Four sides of the rectangular-ambulatory-plane partition with outer wall is vertical is fixedly connected, the quantity of the rectangular-ambulatory-plane partition is no less than one, Back Word
It is connected between shape partition by dowel；The outer wall both ends are equipped with end plate, and the end plate and rectangular-ambulatory-plane partition pass through dowel
Connection, the outer wall are equipped with the first venthole, and the first venthole is rectangular opening；The end plate and rectangular-ambulatory-plane partition are equipped with the
Two ventholes, the second venthole are round hole.The outer wall and rectangular-ambulatory-plane separator material are gray cast iron.
Preferably, rectangular-ambulatory-plane partition quantity is 20, and beam deformation amplitude is minimum at this time, and crossbeam mechanical property is best.
The utility model has the advantages that the crossbeam design of Longmen machine tool is rationally, crossbeam uses rectangular-ambulatory-plane diaphragm structure, and partition arrangement simply has
Rule has good craftsmanship；Rectangular-ambulatory-plane diaphragm structure can promote torsion stiffness, reduce the deformation of Y-direction, while in order to subtract
Small bending deformation；Increase dowel between end plate and rectangular-ambulatory-plane partition, formed engraved structure can loss of weight will not reduce cross
The mechanical property of beam.In process, the stability of crossbeam is significantly improved, and guarantees the stabilization of machine tool accuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional structure schematic diagram of the utility model；
Fig. 3 is plate muscle structural schematic diagram inside the front end face of the utility model.
Specific embodiment
The embodiments of the present invention are described further with reference to the accompanying drawing:
Referring to Fig. 1, the crossbeam of the Longmen machine tool of the utility model includes outer wall 1, and outer wall 1 is transversely equipped with rectangular-ambulatory-plane partition
2, since welding structure bending resistance torsional rigidity is inadequate, crossbeam is using casting processing, outer wall 1 and 2 material of rectangular-ambulatory-plane partition selection ash
Cast iron, four sides of rectangular-ambulatory-plane partition 2 with outer wall 1 is vertical is fixedly connected, due to using 2 structure of rectangular-ambulatory-plane partition, rectangular-ambulatory-plane every
Plate 2 arranges simple regular, has good craftsmanship；2 structure of rectangular-ambulatory-plane partition can promote torsion stiffness, reduce Y-direction
Deformation, while in order to reduce bending deformation；The quantity of rectangular-ambulatory-plane partition 2 is no less than one, preferably selection 2 quantity of rectangular-ambulatory-plane partition
It is 20, beam deformation amplitude at this time is minimum, and crossbeam mechanical property is best；1 both ends of outer wall are equipped with end plate 3, the end
Plate 3 and rectangular-ambulatory-plane partition 2 are connect by dowel 4, formed engraved structure can loss of weight will not reduce the mechanical property of crossbeam；
The outer wall 1 is equipped with the first venthole 5, and the first venthole 5 is rectangular opening, and the end plate 3 and rectangular-ambulatory-plane partition 2 are equipped with the
Two ventholes 6, the second venthole 6 are round hole.First venthole 5 and the second venthole 6 can not only ventilate, but also played and subtract
Heavy, sand removal effect.
Referring to fig. 2, it is connected between the rectangular-ambulatory-plane partition 2 in the utility model also by dowel 4, had formed engraved structure both
Energy loss of weight will not reduce the mechanical property of crossbeam.
Be the 7 inside sheet-beam structure of front end face of the utility model referring to Fig. 3, it is seen that crossbeam plate muscle genesis analysis account for compared with
Large scale has a distinct increment then resisting bending ability accordingly.
It should be pointed out that the utility model implement the technical solution method and approach it is very much, the above is only this
The preferred embodiment of utility model.For those skilled in the art, the utility model original is not being departed from
Under the premise of reason, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the protection model of the utility model
It encloses.All undefined components in this embodiment can be implemented in the prior art.
