Description
Technical field
The invention belongs to Longmen machine tool device field, especially the numerical control gantry machine pillar beam composite guide rail structure of machinery manufacturing industry.
Technical background
The many important industries of China all need high-precision, large-scale moving beam numerical control gantry equipment as generating equipment (water power, wind-powered electricity generation, nuclear power), Aeronautics and Astronautics, boats and ships, auto manufacturing.Large-scale moving beam numerical control gantry machining tool is the urgtented need equipment of modern equipment manufacture, and along with the continuous growth of China's economy, country more and more payes attention to the development of heavy type numerical control plane milling and boring machine project relevant industries.The planer type numerical control lathe of machinery manufacturing industry extensive use at present.The guide rail that moving crossbeam moves---column guide rail, critical component for moving beam numerical control gantry formula lathe, guide rail is the sliding pair that two relative movement part composition surfaces are formed, support unit and execution unit coupling by lathe form, guide rail is the heart of lathe, be one of vitals of lathe, it determines rigidity, precision and the precision stability of lathe to a great extent, is one of greatest factor that guarantees machine finish.
The guide rail that modern Digit Control Machine Tool uses mainly contains 3 kinds, and they are rail plate, rolling guide and hydrostatic slideway.
1, rail plate is divided into rectangle rail plate and circular rail plate, and the rectangular guideway advantage is simple in structure, makes, checks and repair conveniently; The guide pass broad, bearing capacity is bigger, and the rigidity height is so be widely used.But guide clearance needs with pressing plate or panel adjustment, and need readjust after the wearing and tearing, and contact stiffness is low.For guaranteeing the guide rail operate as normal, should keep suitable gap between the guide rail slidingsurface.The gap is too small, can increase frictional resistance; Excesssive gap can reduce guiding accuracy.The gap of guide rail relies on scraping to guarantee, take the very big amount of labour, and guide rail can increase the gap because of wearing and tearing through after using for a long time.Circular guideway is easily manufactured, and cylindrical adopts grinding, and endoporus grinds and can reach accurate cooperation, but can not the adjusting play after the wearing and tearing.For preventing to rotate, can spline or process the plane at periphery, but can not bear big moment of torsion, should be used to bear the occasion of axial load.
2, the characteristics of linear rolling track are that frictional resistance is little, the motion light and flexible; It is little to wear and tear, and can keep precision for a long time, and dynamic and static coefficient of friction difference is little, is not prone to " creeping " phenomenon during low speed, so the motion uniform and stable.The shortcoming of rolling guide is, guide pass and rolling element are to contact or the line contact, and shock resistance is poor, and contact stress is big, so the case hardness of guide rail is required height; To the form accuracy of guide rail and the dimension precision requirement height of rolling element.
3, the hydrostatic slideway advantage is that the variation of guide rail movement speed is very little to the influence of oil film thickness; The variation of load is very little to the influence of oil film thickness; The liquid sassafras that rubs, the sassafras coefficient that rubs only is about 0.005, the oil film good anti-vibration.Shortcoming: guide rail self structure more complicated; Need to increase a cover oil supply system; Clean-up performance requirement to lubricating oil is very high, cost height, maintenance difficult.
Goal of the invention
It is not high to the present invention is directed in the above-mentioned technology in the rail plate the big precision in rectangle gap, circular guideway can't bear high pulling torque, rolling guide shock resistance difference contact stress is big, the weak point that the hydrostatic slideway cost is high, a kind of guide rail face width is provided, bearing capacity is big, and rigidity is high and can regulate the upright post/beam composite guide rail structure of Longmen machine tool in gap.
Realize that technical scheme of the present invention is as follows:
