Description

A kind of planer-type high-precision numerical control EDM shaping machine structure of optimal design
Technical field
The utility model relates to a kind of planer-type high-precision numerical control EDM shaping machine structure of optimal design.
Background technology
Current, on market, high-precision numerical control EDM shaping machine is mainly based on famous foreign brand, and no matter the EDM shaping machine of home brands is by comparison in machine tool capability, precision, or stability aspect all also exists larger gap.The domestic EDM shaping machine that common are column (C type) structure and ram type (cattle-head) structure two kinds of structures, the structure of ram type makes the precision of its main shaft associated components comparatively large by the impact of gravity, and Fig. 9 gives existing ram type machine tool chief axis associated components and distortion schematic diagram thereof.As seen from the figure, level and smooth pillow and coupled vertical shaft base, vertical ram deform by the effect of gravity, and along with they are along cross saddle to the movement of+Y-direction, deflection also can constantly increase, and rigidity is also along with variation.
For ram type structure, because the change that the position of working head causes each parts stressed with the movement of ram, long-term accuracy is unstable, as shown in Figure 10.Meanwhile, cause the stroke of axle to be also restricted owing to smoothly resting the head on the long rigidity variation that overhangs, guide rail parallelism error is also amplified along with the increase of Mold processing (deflection); The designing requirement lathe bed of this structure is heavy, working head is light, and this can cause lathe bed to be subject to the change of temperature comparatively slow, and working head is comparatively responsive by the change of temperature, and this uneven structure of being heated can cause the precision of lathe to change by the change of temperature, and heat endurance is poor.
Column spark-erosion machine tool relies on the movement of workbench to realize the motion of X/Y axle, thus the precision of these two axles and the weight of workpiece closely related, its dynamic accuracy and rigidity all can be affected.Simultaneously, the stroke of X/Y axle is restricted because workbench need move in narrow and small limited space, if design the workpiece that processing is slightly bigger, then the base of lathe and column can more aobvious maximizations, relative to lathe size, can machining area obviously less than normal, and rigidity also can along with stand column and beam overhang lengthen and be deteriorated.This structure should not design, install Liftable type work tank, and working solution easily spills along with the continuous translation of workbench.
Due to the problem that these two kinds of machine tool structures itself are inherent, cause in the use of reality, directly have influence on part or mould machining accuracy and surface quality, therefore must pass through the correct type selecting of machine tool structure and optimal design, particularly seek corresponding solution for these two kinds of structure Problems existing.
Relative to ram type structure, planer type structure is because working head is suspended on portal frame, and stressing conditions can not change with the position of main tapping, long-term accuracy can keep stable, main tapping can arrive any one corner of work top, and stressing conditions is all consistent, as shown in figure 11.Meanwhile, overhang short due to working head and immobilize, good rigidly, affect less by external force, parallelism error also minimizes; The lathe bed of this structure, working solution and portal frame can realize bulk temperature and control, thus realize high accuracy and the heat endurance of lathe.
Relative to high column structure, planer type structure (driven portal formula) maintains static because of platen, and each motion of bar axle has nothing to do with the weight of workpiece and working solution, and its dynamic accuracy and rigidity can not be affected.This structure is convenient to design, is installed Liftable type work tank, moves when oil groove can fill working solution, with the position automatic lifting of electric discharge processing and forming, saves punching and puts the time.
By relatively finding out above, planer type structure is except avoiding the immanent structure problem of ram type structure and high column structure, and lot of advantages own also just in time can meet the various requirement of high-accuracy EDM shaping machine, this lathe good rigidly, precision is high, good stability.Therefore planer type structure is the first-selected frame for movement of design high-precision numerical control EDM shaping machine.As shown in figure 11.But because gantry structure is comparatively complicated, manufacture more difficult.Planer type structure is applicable to large and medium-sized EDM shaping machine and adopts.
And towards the huge market demand, in conjunction with the requirement of precision component and tool and mould technical development, existing EDM shaping machine can not meet some customer demands, I takes charge of equipment Imported From German EMH Company Ou Jisuo advanced technology, specially for the demand of some high-end customers, design is optimized to the gantry structure of high-accuracy spark-erosion sinking lathe, successfully develops technological precedence, superior performance, moderate middle-size and small-size planer-type high-precision numerical control EDM shaping machine (hereinafter referred to as G450C lathe).
