I. Kev Npaj Ua Ntej Siv: Kev ntxuav thiab tshuaj xyuas
Ua ntej kev hloov kho, xyuas kom lub rooj ua haujlwm huv si thiab tsis muaj kev puas tsuaj:
1. Ua kom huv si huv lub chaw ua haujlwm: Siv lub tshuab ntxhua khaub ncaws thiab cov lint -dawb daim ntaub kom tshem tawm cov roj, plua plav, thiab vuam slag residue los tiv thaiv impurities los ntawm kev ntsuas qhov tseeb.
2. Tshawb xyuas qhov tsis xws luag: Saib xyuas qhov khawb, dents, lossis qhov chaw deformation, ua tib zoo saib seb T- cov qhov thiab qhov chaw qhov chaw raug thaiv lossis hnav.
3. Paub meej tias Fixture Integrity: Txheeb xyuas tias qhov chaw pins, cov phaj siab, ceev clamps, thiab lwm yam khoom siv tau ua tiav thiab txav mus los kom ntseeg tau tias cov clamping txuas ntxiv txhim khu kev qha.
Kev huv huv tsis yog tsuas yog kev nyiam huv xwb tab sis kuj yog thawj kauj ruam ntawm kev ua kom raug.
II. Coarse Adjustment: Basic Leveling Kho (Macroscopic Stability)
Lub hom phiaj yog txhawm rau tshem tawm kev ntxhov siab los ntawm kev teeb tsa tsis raug thiab xyuas kom meej txawm tias quab yuam kev faib tawm ntawm cov ntsiab lus txhawb nqa.
1. Xaiv cov cuab yeej ntsuas tsim nyog: Siv 00-qib coincidence qib lossis qib hluav taws xob. Calibrate nws qhov tseeb ua ntej ntsuas.
2. Siv txoj kev "Peb-Point Surface": Ua ntej, kho peb lub ntsiab lus txhawb nqa ntawm lub platform kom muab cov npuas rau hauv ib qho kev taw qhia (piv txwv li, sab ntev); tom qab ntawd kho qhov taw tes thib plaub kom theem nws nyob rau hauv txoj kab ntsug (piv txwv li, sab luv); rov ua dua - ntsuas thiab nplua -tu kom txog thaum cov kev nyeem nyob rau hauv tag nrho cov lus qhia zoo ib yam.
3. Tighten Anchor Bolts: nruj nreem tag nrho cov kev txhawb nqa bolts kom tsis txhob xoob thiab deformation theem nrab.
4. Kev Tswj Ib puag ncig: Tsis txhob muaj lub hnub ci ncaj qha, cua, lossis cuam tshuam kev co. Xyuas kom qhov kub thiab txias yog sib npaug nrog lub rhiav ib puag ncig los tiv thaiv thermal expansion thiab contraction los ntawm kev cuam tshuam cov txiaj ntsig.
Cov theem no tsis ua raws qhov tseeb kawg tab sis tsim kom muaj qhov ntsuas ruaj khov rau qhov zoo -tuning.
III. Fine-tuning: Kho qhov Flatness ntawm Qhov Chaw Ua Haujlwm (Microscopic Precision) Rau qhov tsis sib xws hauv cheeb tsam tom qab vuam kho lossis siv sijhawm ntev - siv sijhawm, siab- yuav tsum tau ua kom tiav machining.
Txoj Kev 1: Phau Ntawv Scraping (Suitable rau siab -qhov yuav tsum tau muaj tseeb)
Tiv tauj Point Inspection: Siv cov xim liab coj mus rau qhov chaw tiaj tus qauv thiab rub nws tawm tsam workpiece nto, kos cov ntsiab lus siab tshaj plaws.
Scraping Successive: Txhua kauj ruam scraping yog tswj ntawm 0.003-0.005 hli. Rov qab xyuas kom txog thaum qhov sib chwv qhov ceev yog ntau dua lossis sib npaug rau 16 ntsiab lus / 200mm × 200mm.
Qhov zoo: Ua tiav flatness Tsawg dua lossis sib npaug ntawm 0.03mm / m, ib txwm siv "tus qauv kub" txoj kev.
Txoj Kev 2: Mechanical Milling (Suitable for loj - thaj tsam kho sai)
Kho lub platform mus rau lub tshuab gantry milling, siv lub nraub qaum phaj raws li kev siv rau kev sib tw.
Siv lub disc milling cutter los ua ib zaug xwb - dhau precision milling ntawm tag nrho cov workpiece nto.
Qhov zoo: Kev ua haujlwm siab, tsim nyog rau kev kho tag nrho ntawm lub platform loj.
Scraping yog tsim rau me me - cheeb tsam, siab - kho qhov tseeb, thaum milling yog tsim rau loj - cheeb tsam, kho sai sai.
IV. Qhov tseeb Calibration thiab Verification
Tom qab hloov kho, cov nyhuv yuav tsum raug txheeb xyuas siv cov cuab yeej tshaj lij:
1. Laser Interferometer Scanning: Xyuas tag nrho cov flatness kom nws ua tau raws li lub Hoobkas qauv (feem ntau tsawg dua los yog sib npaug rau 0.15mm / 1000mm);
2. Coordinate Measuring Machine Verification: Txheeb xyuas qhov kev kam rau siab ntawm qhov chaw qhov tseem ceeb, yuav tsum tau nyob rau hauv ± 0.05mm;
3. Tsis tu ncua Re- kuaj Mechanism: Nws raug nquahu kom ua qhov ntsuas ntsuas txhua txhua 6 lub hlis txhawm rau txheeb xyuas qhov sib txawv me me.
Calibration tsis yog ib qho haujlwm - lub sijhawm, tab sis yog ib feem tseem ceeb ntawm kev saib xyuas tas li.
V. Cov lus qhia txog kev tu txhua hnub
1. Tig qhov chaw siv: Tsis txhob ntev - lub sij hawm thauj khoom tsis sib npaug thiab siv "kev sib hloov hauv cheeb tsam" los faib cov khoom thauj;
2. Txau Anti-spatter Liquid: Txo weld slag adhesion thiab tiv thaiv lub rooj saum npoo mesh qhov thiab T- qhov chaw;
3. Txwv tsis pub cuam tshuam lossis Arc Ignition: Tiv thaiv kev puas tsuaj thiab hluav taws xob corrosion;
4. Kev tiv thaiv xeb thaum tsis ua haujlwm: Siv xeb- tiv thaiv cov roj thiab npog nrog cov ntaub plua plav.
