Abstract
The utility model relates to a large-span high-rigidity cross beam structure of a high speed processing machine tool, comprising U-steel and a through straight rib; the cross beam structure is an integrated box type structure formed by welding, and the central part of the cross beam structure is formed by the U-steel in a relative welding way; the through straight rib is welded along the longitudinal direction of the U-steel; and a cavity is formed on a cross beam in the vertical direction of the U-steel through a rib plate. The large-span high-rigidity cross beam structure can solve the problem that in the prior art, the cross beam of a cast structure limits the performance of a high speed machine tool.
Description
Technical field
The utility model belongs to the high-speed processing machine tool part field, particularly relates to the high rigid beam structure of the big span of a kind of high-speed processing machine tool.
Background technology
Essential characteristics such as high-speed processing machine tool is to follow modern project material technology, improving of microelectric technique and efficient, the high-performance machining tool that grow up, and it has the cutting speed height, and feed speed is fast, and acceleration is big.High cutting speed aspect can replace traditional frame for movement main shaft to realize by making the electricity consumption main shaft, so how to improve the feed speed of lathe and a great problem that acceleration just becomes the development of restriction high-speed processing machine tool.
Traditional machine tool adopts the cast structure crossbeam, and inner reinforcement thickness is 20-30mm.Because casting manufacturability restriction, the interior tendon chamber must evenly be arranged, this makes in order to concentrate the position to increase muscle chamber density at some stress and to have to the whole muscle of crossbeam chamber quantity is increased, make the unnecessary increase of crossbeam weight, remarkable by the caused deflection deformation of deadweight, 8m long beam deformation quantity is between 0.06-0.08mm; And because the restriction of material behaviors such as the elastic modelling quantity of cast iron and tensile strength makes it become the bottleneck of high-speed machine tool performance boost.
Summary of the invention
Technical problem to be solved in the utility model provides the high rigid beam structure of the big span of a kind of high-speed processing machine tool, to solve the problem of cast structure crossbeam restriction high-speed machine tool performance in the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: provide the big span of a kind of high-speed processing machine tool high rigid beam structure, comprise channel-section steel and elongated straight muscle, the whole box-structure that described beam structure forms for welding, its core is welded relatively by channel-section steel, vertically be welded with elongated straight muscle along channel-section steel, described channel-section steel vertical direction forms cavity by gusset on crossbeam.
Described channel-section steel vertical direction forms cavity by gusset on crossbeam.
Beneficial effect
2/3 of the casting beam that crossbeam weight of the present utility model is same size.The deflection deformation amount is 1/2 of a casting beam.Not only increase the dynamic and static rigidity of complete machine but also reduced the inertia of the weight and the transmission system of moving component greatly, reduced lathe drive system specification, reduction lathe cost.
Use the utility model can also shorten the manufacturing cycle of product,, and avoided a series of relevant issues such as the environmental pollution that brings in the crossbeam casting process and the wasting of resources, reach energy conservation and environment protection for enterprise brings bigger economic benefit.
Adopt welded crossbeam improving the dynamic and static rigidity of high-speed processing machine tool; reduce moving-member inertia; improve lathe and cutter life; increase aspects such as complete machine machining accuracy and reliability and have the not available many advantages of casting beam; and increasing the business economic benefit; save resource, also there is own powerful advantage aspects such as protection environment, and the Welding Structure crossbeam of therefore carrying out in an all-round way on high-speed machining center is imperative.

Fig. 2 is a front view of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1 and Figure 2, the utility model comprises channel-section steel 1 and elongated straight muscle 2, the whole box-structure that described beam structure forms for welding, its core is welded relatively by channel-section steel 1, vertically be welded with elongated straight muscle 2 along channel-section steel, described channel-section steel vertical direction forms cavity by gusset 3 on crossbeam.Described channel-section steel 1 vertical direction forms cavity by gusset 3 on crossbeam.
The stock that the utility model selection is welded as crossbeam with the big steel of elastic modelling quantity, adopt whole box-structure, core is that two groups of channel-section steels of 12mm are welded relatively by thickness, vertically weld 8 elongated straight muscle along channel-section steel, thickness is 16mm, this kind method for designing makes the crossbeam die cavity simplify difficulty that reduces to weld and deflection under the prerequisite that satisfies the crossbeam rigidity as far as possible.The vertical channel beam direction is separated into some little cavitys by gusset with crossbeam, the stress of finding the crossbeam coupling part through finite element analysis is comparatively concentrated, so the cavity space that we will locate reduces, and the mid portion of crossbeam, the flexural deformation that needs opposing to bring because of the weight of crossbeam deadweight and saddle ram, therefore cavity strengthens the bending resistance that increases crossbeam at interval herein, and can reduce the centre position amount of deflection deformation that is caused by the crossbeam deadweight.
