Description
Technical field
The present invention relates to a kind of movable gantry Digit Control Machine Tool.
Background technology
What the support component of existing lathe all adopted is metal, ironcasting or steel plate weldment, and the shortcoming that adopts this material to bring is, temperature influence changes greatly, and STRESS VARIATION is arranged, and conducting electricity, be subject to magnetic force influences, and acid and alkali-resistance is not prone to get rusty.In the machine tooling process, when the sand holes of milling to workpiece, rigidly be mingled with or during parts such as milling superhard material, can produce local interrupted milling or cutting vibration ripple; Because the cast iron damping and amortization is little and be mostly can not effectively stop or eliminate vibration wave, along with these continuity of vibration wave on machine tool components such as lathe bed, crossbeam by cavity; Will influence the continuity of cutter milling; Produce small chatter mark at surface of the work, will impact, receive the influence of these factors the surface of the work precision; Especially high precision lathe, precision are difficult to improve.
Summary of the invention
The object of the present invention is to provide a kind of movable gantry Digit Control Machine Tool, solve the above problems.
The technical solution adopted for the present invention to solve the technical problems is: a kind of movable gantry Digit Control Machine Tool, and comprise workbench, X axle, crossbeam on Digit Control Machine Tool body and the Digit Control Machine Tool body, be fixed on slide and Z axle on the crossbeam, it is characterized in that; Described X axle is two, parallel placement, and the X axle is the spill cuboid; In be provided with leading screw; On the X axle, be provided with X axle balladeur train, the two ends of crossbeam are separately fixed on the two X axle slides, also are provided with slide on the crossbeam; Slide drives through the leading screw that is fixed on crossbeam, and the Z axle is fixed on the slide; The side of described X axle is provided with at interval groove uniformly, and the side that groove is parallel to X axle bottom surface also is provided with anchor (bolt) hole; Described X axle, X axle balladeur train, crossbeam and workbench adopt the granite material; Be equipped with a plurality of connecting holes of being connected to a fixed with other parts of being used on described X axle, X axle balladeur train, crossbeam and the workbench, all be inlaid with tapped connector in the described connecting hole;
Described slide and Z axle also can be the granite material material.
The invention has the beneficial effects as follows: through adopting granite entity X axle, X axle balladeur train, crossbeam and workbench, corrosion resistance is strong, does not feel magnetic, and non-corrosive is prone to cleaning; Linear expansion coefficient is little, and wearability is high, and collision or scuffing back are whole indeformable, unstressed influence; Need not Ageing Treatment, shock resistance is good, can effectively absorb the nuisance vibration ripple in the milling process; Eliminate the surface of the work chatter mark, thereby improve surface of the work machining accuracy about 30%, and can improve tool life 37%.

The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of movable gantry Digit Control Machine Tool comprises workbench, X axle 1, crossbeam 2 on Digit Control Machine Tool body and the Digit Control Machine Tool body, is fixed on slide 3 and Z axle 4 on the crossbeam 2, it is characterized in that; Described X axle 1 is two, parallel placement, and X axle 1 is the spill cuboid; In be provided with leading screw 5, on X axle 1, be provided with X axle balladeur train 6, the two ends of crossbeam 2 are separately fixed on the two X axle balladeur trains 6; Also be provided with slide 3 on the crossbeam 2, slide 3 drives through the leading screw that is fixed on crossbeam 2, and Z axle 4 is fixed on the slide 3; The side of described X axle 1 is provided with at interval groove 11 uniformly, and the side that groove 11 is parallel to X axle 1 bottom surface also is provided with anchor (bolt) hole 12; Described X axle 1, X axle balladeur train 6, crossbeam 2 and workbench adopt the granite material; Be equipped with a plurality of connecting holes of being connected to a fixed with other parts of being used on described X axle 1, X axle balladeur train 6, crossbeam 2 and the workbench, all be inlaid with tapped connector in the described connecting hole;
Described slide 3 also can be the granite material material with Z axle 4, and stable shock absorption is splendid, no machining stress, and thermal deformation is minimum, has effectively guaranteed machining accuracy.
Crossbeam 2 adopts the high-quality natural granite to form through the constant temperature attrition process with X axle balladeur train 6, and stable shock absorption is splendid, no machining stress.Crossbeam 2 adopts planer type structure, and two X axle balladeur train 6 wide contact-making surfaces support, and the compact conformation rigidity is strong, reduces to bore boring and milling greatly and cuts torsion in the process, thereby effectively reduce distortion and guarantee precision.
The movable gantry Digit Control Machine Tool is mainly served mechanical processing industry, and die industry is suitable for the plane of materials such as milling and grinding steel part, cast iron, non-ferrous metal and part be nonmetal, and is high to requirement on machining accuracy.
There is following characteristic in granite material:
(1), Shore hardness is 3 times of cast iron, wear-resistant, acidproof, alkaline-resisting, corrosion resistance, indeformable under the weight;
(2), linear expansion coefficient is 1/2nd of cast iron, heat endurance is 20 times of cast iron, it is minimum to meet thermal deformation, good stability;
(3), the damped coefficient ability of absorbing vibration (stop) is bigger 10 times than cast iron, and is mostly solid, resistance shake, shock absorption are strong.
(4), the granite nonmetallic materials, the plastic-less deformation does not also have magnetic reaction, rigidity, physical characteristic retentivity are good;
(5), can not get rusty maintaining convenience, longer service life.The processing of stone energy consumption is low, pollution-free and take from the Nature, and environmental protection has very high social benefit.
In the machine tooling process, when the sand holes of milling to workpiece, rigidly be mingled with or during parts such as milling superhard material, can produce local interrupted milling or cutting vibration ripple; Traditional machine tool adopts cast iron materials, and damping and amortization is little and be mostly can not effectively stop or eliminate vibration wave by cavity; Along with these continuity of vibration wave on machine tool components such as lathe bed, crossbeam, will influence the continuity of cutter milling, produce small chatter mark at surface of the work; To impact the surface of the work precision; And the present invention can effectively absorb the nuisance vibration ripple in the milling process through adopting granite entity X axle, X axle balladeur train, crossbeam and workbench, eliminates the surface of the work chatter mark; Thereby improve surface of the work machining accuracy about 30%, and can improve tool life 37%.
