I. Direct Judgement Basis: Tshaj cov qauv hauv cov ntaub ntawv xeem
Thaum qhov kev ua yuam kev flatness pom los ntawm cov cuab yeej tshaj lij tshaj li lub Hoobkas, kev hloov kho yog tsim nyog. Cov kev txiav txim siab rau cov qib raug yog raws li hauv qab no:
Platform theem: Flatness tsawg dua los yog sib npaug rau 0.15mm / 1000mm
Precision Level Platform: Flatness Tsawg dua lossis sib npaug rau 0.10mm / 1000mm
Siab -Precision Level Platform: Flatness Tsawg dua lossis sib npaug li 0.05mm / 1000mm
Yog tias qhov ntsuas tus nqi siab tshaj tus qauv qib sib xws, lossis ib zaug - lub caij hloov pauv piv rau cov ntaub ntawv xeem dhau los yog> 0.02mm / 1000mm, nws qhia tau tias lub platform tsis tu ncua deforming thiab yuav tsum muaj kev cuam tshuam raws sijhawm.
II. Cov teeb liab txawv txav hauv cov txheej txheem tsim khoom (Kev txiav txim ncaj qha)
Txawm hais tias lub voj voog soj ntsuam tsis tu ncua tseem tsis tau tuaj txog, cov txheej txheem hauv qab no qhia tau hais tias qhov flatness yuav tsis raug:
1. Workpiece Positioning Misalignment
Tom qab lub fixture los yog positioning tus pin yog muab tso rau, lub workpiece txoj hauj lwm tsis phim tus tsim, thiab rov kho tsis tau reliably reproduce qhov yuam kev.
2. Weld misalignment lossis qhov tsis sib xws: Yog tias cov khoom ua haujlwm los ntawm tib lub batch yog welded nyob rau hauv tib lub fixture thiab pom tsis tu ncua misalignment los yog tsis zoo sib tshooj, tom qab txiav txim tawm qhov kev pab cuam thiab fixture teeb meem, platform deformation yuav tsum xav tias.
3. Nyuaj lossis xoob hauv qhov kev sib dhos / tshem tawm: Yog tias qhov chaw pins tau daig lossis wobble pom zoo thaum muab tso, nws yuav yog vim muaj kev cuam tshuam ntawm lub qhov system los ntawm lub platform warping.
4. Muaj qhov sib txawv ntawm cov pob qij txha ntawm ntau lub platform: qhov siab qhov sib txawv lossis qhov tsis zoo ntawm cov pob qij txha ua rau tsis muaj kev cuam tshuam ntawm tag nrho cov ntaub ntawv nto tom qab sib dhos.
⚠️ Kev ceeb toom tshwj xeeb: Yog tias muaj teeb meem zoo sib xws tshwm sim ib txhij ntawm ntau qhov chaw ua haujlwm, ua ntej xyuas seb lub ntsiab lus siv lub platform puas yog deformed.
III. Yooj yim ntawm - txoj kev tshuaj xyuas qhov chaw (tsis muaj cov cuab yeej tshaj lij yuav tsum tau): Thaum siab - cov cuab yeej muaj tseeb tsis muaj, cov hauv qab no tuaj yeem siv rau kev txiav txim siab sai:
1. Knife-edge ruler + feeler gauge method: Place a knife-edge ruler against the platform and use a feeler gauge to measure the gap. If the gap is >0.05mm nyob rau hauv ib tug 250mm ntev, nws qhia tau hais tias tseem ceeb hauv zos bulges los yog kev nyuaj siab.
2. Standard Square Measurement: Use a precision square against the side and a feeler gauge to check the verticality. If the gap is >0.1 hli nyob rau hauv ib qhov siab 200 hli, nws qhia tau hais tias qhov chaw siv yog tilted.
3. Red Lead Lapping Method: Siv cov hlau lead liab mus rau qhov chaw tiaj tus qauv thiab lapped tiv thaiv qhov chaw ua haujlwm. Yog hais tias cov ntsiab lus sib txuas yog sib sib zog nqus los yog muaj zog ntawm cov npoo, nws qhia tias tsis zoo.
✅ Kev Pom Zoo: suav nrog cov txheej txheem no hauv daim ntawv tshuaj ntsuam xyuas niaj hnub ua thawj kab ntawm kev tiv thaiv kev tiv thaiv kev saib xyuas.
IV. Kev Kho Cov Kev Xav Tau Ua los ntawm Ib puag ncig thiab Kev Pabcuam
Cov xwm txheej hauv qab no yuav tsum tau kuaj xyuas thiab hloov kho txawm tias tsis pom qhov txawv txav:
Platform tau ntsib lub sijhawm tseem ceeb ntawm kev ua haujlwm siab - qhov kub thiab txias (piv txwv li, kev ua haujlwm tas mus li - thauj khoom rau ob peb hnub);
Kev cuam tshuam los ntawm cov khoom hnyav lossis hoisting tsis raug ua rau muaj kev ntxhov siab hauv lub platform;
Kev kho hauv pem teb lossis cov cuab yeej hloov chaw hauv lub rhiav, uas yuav cuam tshuam rau lub hauv paus ruaj khov;
Kev rov ua dua tom qab ntev - tsis siv sijhawm ntev, xav tau kev lees paub tias cov ntaub ntawv siv tau raug tswj xyuas.
📌 Kev ceeb toom tus phooj ywg: Ua qhov kev tshuaj xyuas txhua lub hlis twg los tsim "cov ntaub ntawv sib luag" thiab paub txog kev hloov pauv los ntawm kev saib xyuas tsis tu ncua mus rau kev tswj hwm.
