Yuav ua li cas txheeb xyuas tus ntsuj plig
Kev tshuaj xyuas ntawm qib ntsuj plig yuav tsum tau ua raws li cov qauv sib xws. Qhov ntsuas kub hauv chav kuaj xyuas yuav tsum yog 20 ± 2 degree, thiab kev tshuaj xyuas yuav tsum tau ua raws li qhov kev ruaj ntseg, tsis muaj kev vibration, thiab deb ntawm qhov chaw kub. Ua ntej kev soj ntsuam, txhua qhov chaw ntawm qib yuav tsum tau txhuam kom huv si, thiab tom qab ntawd cov qib yuav tsum tau muab tso rau ntawm lub phaj hlau hauv chav kuaj xyuas, thiab tib lub sijhawm kub yuav tsum tsis pub tsawg dua 3 teev.
Kev tshuaj xyuas qhov muag
Rau lub Hoobkas tshiab qib siab, qhov chaw ua haujlwm yuav tsum tiaj tus, du thiab tsis muaj qhov tsis xws luag xws li hlwv, pores, bruises, khawb, thiab corrosion. Cov xim pleev xim, xeb thiab pom tseeb tsis raug tso cai rau ntawm qhov chaw tsis ua haujlwm. Cov theem yuav tsum huv si thiab pob tshab, cov kab engraved yuav tsum meej thiab zoo ib yam, yuav tsum tsis txhob muaj discoloration, thiab engraved kab yuav tsum perpendicular mus rau lub axis ntawm theem. Ntawm qhov tsis ua hauj lwm ntawm tus ntsuj plig, lub npe ntawm cov chaw tsim khoom, tus lej xov tooj thiab tus nqi faib yuav tsum raug cim.
kev sib tham
Cov theem tseem ceeb yuav tsum tau teeb tsa kom ruaj ntseg, thiab xoom hloov kho yuav tsum yooj yim siv thiab txhim khu kev qha. Lub zog ntawm cov npuas yuav tsum du, thiab yuav tsum tsis txhob pom kev dhia lossis stagnation. Thaum chav tsev kub yog 20 degree, qhov ntev ntawm cov npuas yuav tsum sib npaug ntawm qhov deb ntawm ob txoj kab ntev, thiab qhov sib txawv yuav tsum tsis pub tshaj ± 1 faib rau cov uas kawm tiav ntawm {{4} }.02 txog 0 05mm/m; rau kev kawm tiav ntawm 0.06 txog 0.10mm / m yuav tsum tsis pub tshaj ± 0.5 faib. Kev ruaj ntseg ntawm kev txav ntawm cov npuas thiab qhov ntev ntawm cov npuas yuav tsum tau kuaj xyuas ntawm tus ntsuas ntsuas.
ua haujlwm dav hlau
Protrusions tsis raug tso cai rau ntawm qhov chaw ua haujlwm ntawm tus ntsuj plig, thiab nws txoj kev tiaj tus yuav tsum ua kom tau raws li qhov yuav tsum tau muaj hauv Table 6-10-54. Qhov ntev ntawm lub ntsej muag ua haujlwm yog 150-200 250-300, thiab qhov sib txawv flatness yog<0.003 <0.005. For the grinding and grinding working face, the flatness is verified by the zero-level knife-edge ruler whose size is not less than the length of the inspected face, and the light gap method is used for verification , this verification work should be carried out at several positions in the longitudinal, transverse and diagonal directions of the working face. The largest gap seen is the flatness deviation of the surface. When estimating the size of the gap, it can be compared with the standard gap composed of gauge blocks.
Rau qhov flatness ntawm scraped ua hauj lwm nto, siv xoom-theem ca phaj los ntsuam xyuas los ntawm cov xim txoj kev. Tus naj npawb ntawm cov chaw hauv ib cheeb tsam square nrog ib sab ntev ntawm 25 hli yuav tsum tsis pub tsawg tshaj 25 cov ntsiab lus rau ib qib nrog tus nqi faib ntawm 0.02 txog 0.{{ 10}}5mm / m, thiab yuav tsum tsis pub tsawg tshaj 20 rau ib theem nrog tus nqi faib ntawm 0.06 txog 0.10mm / m Cov chaw yuav tsum tau muab sib npaug.
Qhov ncaj ntawm V-shaped ua haujlwm saum npoo yog txheeb xyuas los ntawm txoj kev pleev xim nrog cov ntawv pov thawj mandrel. Muab cov mandrel coated nrog cov hmoov txhuas liab rau ntawm V-shaped nto kom tig, thiab cov kab sib txuas uas pom ntawm V-shaped nto tsis raug tso cai kom muaj qhov tsis sib xws ntawm ntau tshaj 10 hli.
xoom check
Qhov sib txawv ntawm lub npuas los ntawm qhov nruab nrab txoj hauj lwm yuav tsum tsis txhob ntau tshaj 1/4 ntawm tus nqi kawm tiav. Lub xoom txoj hauj lwm tshuaj xyuas ntawm lub ntsej muag ua hauj lwm qis ntawm tus ntsuj plig theem tuaj yeem nqa tawm ntawm xoom-theem tiaj tiaj phaj, lossis nyob rau qib ntsuas ntsuas ntsuas; xoom txoj hauj lwm tshuaj xyuas ntawm qis V-zoo li lub ntsej muag ua haujlwm ntawm qib ntsuas yuav tsum tau nqa tawm ntawm lub cuab yeej tshwj xeeb; rau lub thav duab theem 'meter' Qhov xoom txoj hauj lwm ntawm lub dav hlau sab sauv ua hauj lwm nto, lub Upper V-shaped ua hauj lwm nto, sab dav hlau ua hauj lwm nto thiab sab V-zoo li tus ua hauj lwm nto yuav tsum tau nqa tawm ntawm tshwj xeeb cov cuab yeej.
Kev ruaj ntseg ntawm xoom txoj hauj lwm ntawm qib 'meter' yuav tsum tau hais tias tom qab xoom txoj hauj lwm ntawm lub ntsej muag ua hauj lwm qis dua raug txheeb xyuas, xoom txoj hauj lwm yuav tsum tau xyuas dua nyob rau hauv ib ncua sij hawm ntawm 4 teev, thiab qhov kev hloov yuav tsum tsis txhob ntau tshaj qhov tso cai ntawm xoom. txoj hauj lwm sib txawv.
kev tshawb nrhiav yuam kev
Nws yuav tsum tau nqa tawm ntawm ib theem 'meter' calibrator. Qhov sib txawv ntawm qhov ntsuas nruab nrab lub kaum sab xis thiab tus nqi nominal lub kaum sab xis yuav tsum tsis pub tshaj 10 feem pua ntawm tus nqi nominal. Qhov tsis sib xws ntawm tus nqi kawm tiav yuav tsum tsis pub tshaj 20 feem pua ntawm cov nqi kawm tiav. Ntawd yog, qhov sib txawv ntawm kev nyeem ntawv nyob ib sab yog nyob rau hauv thaj tsam ntawm 0.8 txog 1.2 kev faib. Kev txheeb xyuas qhov kev faib nqi yuam kev ntawm qib ntsuas yuav tsum tau ua nyob rau sab laug thiab sab xis teev ntawm cov npuas. Txhawm rau kom tshem tawm cov kev cuam tshuam ntawm kev tuag nyob deb ntawm lub micro-ntsuab ntsia hlau ntawm qib meter calibrator, micro-motion ntsia hlau yuav tsum tig mus rau hauv ib qho kev taw qhia.
