Hauv kev lag luam Aerospace, cov txheej txheem loj dua {{0} Zoo li cov kev sib tw fusel? Txhua lub sijhawm ib feem yog rov - clamped, feeb Datum explet tshwm sim. Thaum tus kheej tsis lees paub, cov kev hloov no tuaj yeem ua txhaum yuam kev cov yam ntxwv xws li nce qhov thiab cov chaw datum.
Qhov kev sib tw
Qhov teeb meem tseem ceeb yog tsim tsa kev ua yuam kev:
Data Drifttshwm sim nrog txhua re txhua- Camp yog rau qhov sib txawv hauv clamping zog, lossis kho kom nruj.
Koom Tes Ua Khaub Ncawstxhais tau tias txhua lub teeb tsa tshiab tsim thaum yav dhau los ua yuam kev.
Txawm<0.01 mm mismatches become critical when the final assembly tolerance is tight and the part is large.
Tshuaj Yim Zoo
Ib txoj hauv kev sib xyaw tau tsim los tshem tawm qhov yuam kev:
Nchuav Modular fixture tsim
Fixtures tau tsim nrog kev sib xyaw ua ke ntawm cov chaw ua haujlwm Datum, cov yam ntxwv theem nrab, thiab kho cov shims. Cov qauv tsim no tso cai Minimal Repositioning yuam kev thiab hauv {{1} fixture kho kho thaum rov ua- clamping.
Ntau - ntsej muag machining hauv ib qho teeb tsa
Los ntawm kev siv txuas ntxiv - ntev cuab yeej thiab 5 {Axis thiab cov ntaub ntawv loj} Axis thiab cov khoom siv tau {- Kev ua kom rov muaj dua tshiab rov ua haujlwm dua.
Kho qhov cuab yeej kho qhov muag ua haujlwm + hauv - txheej txheem probing
Tom qab txhua tus flip, kho qhov muag -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} rest rest rest rest rest rest rest restor tool tool Tool Datum rau tus tswv siv. Qhov no yog ua raws li nyob rau hauv - tshuab soj ntsuam ntawm cov yam ntxwv tseem ceeb los hloov kho lub cuab tam tau ntsuas cov ntaub ntawv ntsuas.
Qho kawg
| Yam zoo | Ua ntej kev siv | Tom qab siv |
|---|---|---|
| Sau Datum Drift | >0.015 hli | < 0.005 mm |
| Thawj -} pass tawm los | ~80% | > 98% |
| Rhiav vim yog misalignment | Ntau zaus | Tsawg tsawg |
Yog tias koj ntsib kev zam kev khiav tawm hauv loj nyob rau hauv 5 {{1} {{{{{{2} {} txheej txheem tsim kho kom ruaj khov rau hauv ib feem, tsis yuam kev rau hauv datum.
