Abstract
The utility model relates to the technical field of mechanical process equipment, in particular to a planer type numerical control boring and milling machine with a fixed beam structure. The utility model provides the planer type numerical control boring and milling machine with the fixed beam structure, a beam adopts a rectangle major structure, three lead rails are arranged on the beam, one lead rail is distributed at the top face of the beam, the other lead rails are distributed on the front end face of the beam, the stress of the beam is uneven when the existing boring and milling machine works to cause the problems that the lead rails are worn and torn seriously and the precision is lowered. The rigidity, the precision and the accuracy hold life of the rectangle beam of a linear three lead rail structure of the boring and milling machine are better than that of the general two-spherical guide, in particular the increase of the rigidity, the planer type numerical control boring and milling machine with a three spherical guide fixed beam structure can be good for the requirements of the heavy cutting, improve the rigidity of a machine tool, and prolong the accuracy retentivity of the machine tool.
Description
Technical field
The utility model relates to the machining equipment technical field, especially a kind of planer type numerical control boring and milling machine of deciding girder construction.
Background technology
Decide diplodocus gate-type digital-control boring-milling machine and be the processing of big-and-middle-sized parts such as a kind of various casing classes that are widely used in automobile, Aero-Space, metallurgical machinery, printing packaging machinery, textile machine, die industry, refrigeration petrochemical industry and rolling stock industry, frame class, dish class, plate class, precision die.After clamping of workpiece, can finish boring automatically, mill, multiple working procedure processing such as brill, hinge, tapping.Can realize five processing by dress annex cutting head as required,, three the grating chi can be installed all and carry out the precision feedback, make positioning accuracy, repetitive positioning accuracy reach very high level for improving machining accuracy to workpiece.
At present, decide diplodocus gate-type numerical control boring and milling lathe and generally adopt rail plate or two kinds of forms of linear rolling track.The rail plate relative stiffness is better, mostly is used for thick, the semi-finished occasion of heavy load, and rail plate is because coefficient of friction is bigger, and starting torque is very big, and mechanical response is blunt, so positioning accuracy is poor slightly.Linear rolling track has adopted the steel ball of high-quality or steel column as rolling element, coefficient of friction is very little, starting torque is very little, the mechanical response sensitivity, positioning accuracy is very high, because that steel ball and guide rail are that point or line contacts is mobile, though the increase pretightning force, can improve rigidity, but the retentivity of rigidity and precision still is a bit weaker.Through use after a while, machine tool accuracy will be adjusted, otherwise will lose the precision of lathe, the processing of not competent high-precision part.Secondly, carried slide plate and ram on the crossbeam,, generally can not increase the slide block of linear guides, in other words, can not carry out corresponding compensation because of load becomes the quantity that increases slide block greatly owing to structural reason.So the condition of work of the linear rolling track on the crossbeam is relatively poor relatively.
The slide plate of general CNC planer type milling machine and the structure (as shown in the figure) of crossbeam, the weight of slide plate, ram and gearbox is the both sides of the online rail of carrying all, some design becomes beam design the structure of 30 degree skew back formulas, though can divide to fall some load, but main stressed or online rail two sides are so still can not fundamentally improve the situation of quick wearing and tearing.
Summary of the invention
The technical problems to be solved in the utility model is: existing planer type numerical control boring and milling machine when work crossbeam stressedly cause way rub serious all in the side of two guide rails of front end face, cause the problem of precision reduction.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of crossbeam of planer type numerical control boring and milling machine adopts the rectangular cylinder structure, and three guide rails are arranged on crossbeam.Boring and milling machine has lathe bed, workbench, left column, right column, crossbeam, slide plate, ram, main speed reduction box, console, electric control box, compositions such as hydraulic control box, crossbeam has adopted the rectangular cylinder structure, three linear rolling tracks are arranged on crossbeam, two linear rolling tracks distribute in the side of crossbeam, two guide rails of side mainly transmit the precision of slide plate Y direction, at end face single-rail is set, the end face single-rail mainly bears the load of the slide plate ram of Z axle, minimizing is to the load of side guide
The beneficial effects of the utility model are, it is far better that the rigidity of the rectangle crossbeam of linear three guide rail structures of the present utility model, precision and precision keep that the life-span will be than common two spherical guides, especially the increase of its rigidity, the planer type numerical control boring and milling machine that linear three guide rails are decided girder construction can be competent at the requirement of heavy load cutting, improve the lathe rigidity, prolong the machine tool accuracy retentivity.
