Qib 'meter' - qhia txog kev ntsuas ntsuas ntsuas
Kev tshuaj xyuas ntawm qib ntsuj plig yuav tsum tau ua raws li cov qauv coj ua. 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 tshuaj ntsuam xyuas, 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 3h. qib ntsuj plig
(1) Kev tshuaj xyuas qhov tshwm sim: Rau qib siab ntawm lub Hoobkas tshiab, qhov chaw ua haujlwm yuav tsum tiaj tus thiab du, thiab yuav tsum tsis muaj qhov tsis xws luag xws li hlwv, qhov 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.
(2) Kev sib cuam tshuam ntawm txhua ntu:
Lub ntsiab theem yuav tsum tau muab ntsia kom ruaj khov, 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 rau qhov kev ncua deb ntawm ob txoj kab ntev, thiab qhov sib txawv yuav tsum tsis pub tshaj ± 1 faib rau cov neeg uas muaj qhov sib faib ntawm {{4} } 02 txog 0 05mm/m; rau cov uas muaj kev faib tawm 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 qib.
(3) Flatness ntawm qhov chaw ua haujlwm:
Tsis pub muaj protrusions rau ntawm qhov chaw ua hauj lwm ntawm tus ntsuj plig, thiab nws flatness yuav tsum tau raws li qhov yuav tsum tau nyob rau hauv cov lus 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 xyuas 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.
(4) Zero soj ntsuam ntawm tus ntsuj plig theem:
Qhov offset ntawm npuas mus rau nruab nrab txoj hauj lwm yuav tsum tsis txhob ntau tshaj 1/4 ntawm tus nqi kawm tiav. Kev tshuaj xyuas ntawm xoom txoj haujlwm ntawm lub ntsej muag ua haujlwm qis ntawm qib tuaj yeem nqa tawm ntawm lub phaj xoom, lossis ntawm cov ntsuas ntsuas qib; xoom tshuaj xyuas ntawm qis V-zoo li lub ntsej muag ua haujlwm ntawm qib yuav tsum tau nqa tawm ntawm cov cuab yeej tshwj xeeb; rau qib thav duab Qhov xoom txoj hauj lwm ntawm lub dav hlau sab sauv ua haujlwm, sab sauv V-shaped ua haujlwm saum npoo, sab dav hlau ua haujlwm saum npoo thiab sab V-shaped ua haujlwm saum npoo yuav tsum tau nqa tawm ntawm cov cuab yeej tshwj xeeb.
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.
(5) Kev txheeb xyuas ntawm theem faib tus nqi yuam kev:
Nws yuav tsum tau ua nyob rau hauv lub gauge 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.
