Boring machine workbench makes muscle board type and box form of characters or letters, working surface has rectangle, square or circle, material HT200-300, QT400-600, ZG15-45. Working face of boring machine workbench is used blow grind craft, chamfer of end of chamfer of V form, T form, U form, swallow, round hole, long aperture can be machined to wait on working surface. Boring machine workbench is the planar and standard measure that be used at workpiece to detect or underlines. Installation of boring machine workbench is moved to water flat, bear to distributing to go up at each fulcrum equably. Boring machine workbench uses environmental temperature (20±5) ℃ . Vibration should avoid when using. Material is qualitative: Intensity is cast-iron HT200-300, hardness of working face of boring machine workbench is HB170-240, pass artificial processing twice, make the precision of boring machine workbench stable, wear-resisting performance is good. Norms: 1500*2000—3000*6000mm, (workbench of special norms boring machine, make according to needing square blueprint. ) precision: 3 class, by national level metric calibrating regulations is carried out. Of working face of boring machine workbench smooth spending is to point to include actual surface and the distance is the distance between small two parallel area. There is Kong He T chamfer above working surface, use fixed work. Join is placed into luggage when boring machine workbench basically is used at the installation of wind- driven dynamo; The to boring machine workbench requirement when contented trends experiments, assure working dependability. Make the same score working face of boring machine workbench degree of public errand to allow a value, by its numeric size is divided into a few level, call accuracy of cast-iron flat plane. The computation of cast-iron flat flatness is formulary with JB7975-1999 standard 000 class =1* (1+d/1000) Um00 class =2* (1+d/1000) Um0 class =4* (1+d/1000) Um1 class =8* (1+d/1000) Um (D is diagonal Mm) flatness of boring machine workbench collects decided accuracy, it is the assurance of cast-iron flat service mass. The method that the boring machine workbench of common small standards moves a standard is put gradienter on cast-iron flat, of gradienter setting the position is with two bearing below boring machine workbench the dot connects line parallel, fall through rising among them dot of a bearing makes be placed in the middle of gradienter level bubble, place gradienter in next with two bearing the dot connects line photograph perpendicular locally, litre fall 3 bearing dot, make be placed in the middle of gradienter level bubble, adjust repeatedly through afore-mentioned methods, can move boring machine workbench level. But when the flat that should adjust 2000mm×3000mm above, especially the one chunk that many flat constitutes is cast-iron when flat, by afore-mentioned methods air level considers bothered. The method that uses sruveyor's level to lay a target will move cast-iron flat standard, discover this kind of method can raise accuracy not only, and can improve work efficiency. Boring machine workbench disappears model foundry technology flow: Boring machine workbench is made disappear model, set gating system, brush in bubble surface, gush is tailor-made high temperature resistant coating and stoving. On workbench of vibration of park of sandbox of will tailor-made secondary floor, fill a heart arenaceous (dry arenaceous) brace up solid, strickle, put the aerification standard of stoving at the bottom arenaceous on, cram doing is arenaceous, small brace up mouth of box of appropriate time strickle.
Enclothe with plastic film, put runner cup, receive vacuum system to suck vacuum, after dry arenaceous close solid shapes, undertake pouring, bubble aerification disappears, metallic fluid replaces its position.
Release vacuum, the iron that wait for ash turns over box after cast condensation, from work loose arenaceous in take out grey iron cast.
Put sruveyor's level tripod by around, make tripod firm, originally sruveyor's level closely on tripod, do put good sruveyor's level, height gauge is placed on flat strong point, risk one graduation mark to be with what sruveyor's level binoculars aims at height gauge fiducial, ordinal litre fall each strong point of boring machine workbench, so till flat the target above strong point is on same graduation mark, aim at and adjust what pass above twice, boring machine workbench was made the same score with respect to tone. Use DSZ1 sruveyor's level to adjust by the Http://www of boring machine workbench of 5 1500*2000*200mm.
Chinaweiyue.
Com/ , the division of one slip gauge that its accuracy forms for the boring machine workbench of 2 class is the boring machine workbench of 1500*10000*200mm, debug through this kind of method, classics calibrating, flatness of boring machine workbench is 127um. Carry out a proof, using sruveyor's level to aim at the method of the target to adjust level of boring machine workbench is feasible.
