Txhua qhov precision weld pib tsis nrog arc-tab sis nrog rau qhov chaw uas tsis txav mus. A fabrication jig rooj tsis yog steel ntawm ob txhais ceg xwb. Nws yog tus khub uas ntsiag to hauv txhua lub rooj sib txoos uas rov ua dua: lub hauv paus uas tuav lub siab ntev dua li koj GD&T callouts, absorbs vibration ua ntej nws blurs ib fillet, thiab hloov tus neeg teb xov tooj txawj mus rau hauv cov txheej txheem sib xws.
Peb tau saib ntau lub khw caum qhov sib txawv ntawm qhov sib txawv tsuas yog kom paub tias lub hauv paus ua rau tsis muaj cua sov nkag - nws yog ib feem ntawm kev txav thaum clamping. Nyob rau hauv ib txoj haujlwm ua liaj ua teb xyoo tas los, tus neeg siv khoom qhov kev teeb tsa kev ua yuam kev yog qhov nruab nrab ± 0.8 hli hla 12 qhov. Lawv tau hloov kho lawv cov phom MIG, ntxiv cov pa ntxuav, txawm tias tau cob qhia cov welders ntawm cov ntsuas pulse. Qhov kho? Ib tug re-engineered fabrication jig rooj nrog kinematic nrhiav tus pins, hardened dowel bushings, thiab xoom-play toggle clamps. Qhov kawg variation poob rau ± 0.15 mm-hauv spec, tsis muaj rework.
Vim li cas "Tsuas yog Lub Rooj" Tsis Ua Raws Li Lub Ntiaj Teb Loads tiag
Lub rooj jig yuav tsum ua peb yam ib zaug: nrhiav, txwv, thiab ciaj sia. Tsis yog txhua tus ua.
Qhov chaw txhais tau hais tias rov ua dua-tsis yog tsuas yog ntaus tib qhov chaw ib zaug xwb, tab sis ua nws 500 zaug hla kev hloov pauv, hloov pauv kub, thiab cov cuab yeej hnav. Peb siv hauv av stainless hlau nrhiav zes nrog ± 0.01 hli flatness, tsis machined phaj. Kev txwv txhais tau tias tiv thaiv rau qib kev ywj pheej - tsis yog tsuas yog nias, tab sis tiv thaiv nqa, twist, thiab sab nraub qaum thaum vuam thermal expansion. Tias yog vim li cas peb cov ntxhuav integrate welded-hauv T-slot rails nrog load-rated clamping caj npab-tsis bolt-on accessories. Muaj sia nyob txhais tau tias tuav calibration tom qab 3,000+ weld hla, tsis yog ciaj sia thawj lub teeb. Peb ntxhov siab-relieve tag nrho cov hauv paus daim hlau tom qab-machining thiab txheeb xyuas kev ruaj ntseg nrog CMM cheb ua ntej zaum kawg nto sib tsoo. Skimp ntawm ib qho - thiab koj them nyiaj hauv seem, rov ua haujlwm, lossis xa khoom xa tuaj lig. Peb tau pom cov neeg siv khoom hloov $ 120k robotic hlwb vim lawv lub rooj jig warped nyob rau hauv thermal cycling. Kho lub rooj nqi 7% ntawm tus nqi neeg hlau. Thiab xa hauv 11 hnub.
Dab tsi Engineers xav tau tiag tiag - Tsis yog Daim Ntawv Qhia Cog Lus
Qee tus neeg muag khoom sau npe "± 0.05 hli qhov tseeb" yam tsis tau hais txog: chav tsev kub? Tsis muaj thermal so? Unloaded? Qhov tseeb ntawm lub ntiaj teb yog nyob ntawm seb lub rooj coj li cas thaum koj vuam thaum 4 teev sawv ntxov, nrog rau qhov kub thiab txias ntawm 15 ° C thaum hmo ntuj.
Yog vim li cas peb tsim txhua yam fabrication jig rooj rau kev ua haujlwm resilience:
Cov khoom siv hauv pausASTM A572 Qib 50 cov qauv hlau-tsis yog cov hlau me me-kho rau 220-250 HB hardness, ces precision-av mus rau 0.005 hli flatness tshaj 2 m². Mounting system: Integrated 10-mm T-slot rails nrog hardened inserts strips (62 HRC), kuaj rau 12,000 N clamping quab yuam ib ntu. Kev tswj cua sov: Kev xaiv dej-txias lub hauv paus phaj rau kev siv lub luag haujlwm siab-kuaj txog li 200 welds / teev yam tsis ntsuas qhov deflection. Modularity: Standardized interface cov ntsiab lus cia cov neeg siv sib pauv qhov chaw, ntxiv pneumatic clamps, los yog integrate lub zeem muag dlhos lub hom phiaj - tag nrho tsis muaj drilling qhov tshiab. Peb tsis muag "cov rooj." Peb xa calibrated positioning systems. Txhua chav tsev xa khoom nrog CMM daim ntawv qhia tag nrho uas qhia txog kev tiaj tus, kev sib luag, thiab kev tsheb ciav hlau-rau-rail perpendicularity-traceable rau NIST cov qauv.
Tsis muaj qhov tsawg kawg nkaus. Tsis Xav Ua Haujlwm. Tsis muaj kev cuam tshuam rau Traceability
Cov khoom me me yuav tsum tsis txhob txhais cov cuab yeej thib ob. Ib tug European Tier-1 automotive tsum xav tau 14 kev cai jigs-rau cov qauv siv tau ntawm tus tshiab EV roj teeb bracket. Lawv cov neeg muag khoom yav dhau los tau hais txog 12 lub lis piam thiab xav tau 50 units yam tsawg kawg nkaus. Peb xa 14 qhov kev soj ntsuam tag nrho, CAD-validated rooj hauv 16 hnub. Txhua chav tsev suav nrog DFM cov lus taw qhia, cov lus pom zoo ua ntu zus, thiab cov ntaub ntawv pov thawj rau EN 10131 DC04 txias-dov hlau.
Qhov no ua haujlwm vim peb lub peev xwm yog ntsug-tsis yog txheej:
Tsim: Hauv tsev GD&T engineers tshuaj xyuas koj tus qauv 3D thiab chij cuam tshuam kev pheej hmoo ua ntej hais. Tsim: CNC plasma txiav, robotic vuam ntawm substructures, thiab tes-scraped nto finishing-tag nrho nyob rau hauv ib tug ISO 9001-certified ru tsev. Validate: Txhua lub rooj dhau los ua qhov kev sim ua haujlwm nrog cov khoom tsim khoom thiab cov clamps tiag tiag - tsis yog calipers xwb. Kev them nyiaj yug: Tom qab xa khoom xa tuaj, peb khaws koj cov ntaub ntawv CMM, daim ntawv qhia kev sib txuas, thiab kev soj ntsuam kev ua siab ntev rau kev hloov kho yav tom ntej. Tsis muaj outsourcing. Tsis muaj handoffs. Tsis yog "peb yuav kuaj nrog kev tsim khoom." Tsuas yog ib pab neeg - los ntawm kev hais lus mus rau kev ua haujlwm.
Koj cov kauj ruam tom ntej tsis yog lwm nqe lus. Nws yog Validation Protocol.
Ua ntej koj kos npe rau lwm tus fabrication jig rooj, nug: Nws puas tuaj nrog cov ntaub ntawv thermal stability nkhaus? Koj puas tuaj yeem txheeb xyuas nws qhov flatness nyob rau hauv load-tsis yog thaum so? Puas yog qhov chaw nrhiav chaw tsim los rau koj qhov kev ua haujlwm phem tshaj plaws - lossis tsuas yog qhov zoo tshaj plaws geometry?
Botou Haijun Hlau Khoom Co., Ltd. tsim cov rooj jig qhov twg engineering lub hom phiaj ua tau raws li lub khw hauv pem teb kev muaj tiag. Peb tau xa tawm ntau dua 870 qhov tseeb jig tshuab txij li xyoo 2019-rau cov neeg siv khoom hauv lub teb chaws Yelemees tsim cua turbine nacelles, mus rau US ag-tech firms assembling autonomous sprayer frames, to Southeast Asian EMS cov chaw muab kev kho mob robotics chassis. Txhua tus qhia ib qho yuav tsum tau ua: xoom kam rau siab rau txoj hauj lwm drift.
Yog tias koj lub rooj sib txoos tom ntej xav tau rov ua dua-tsis yog kev cia siab- pib nrog qhov tseeb saum npoo. Pib nrog a fabrication jig rooj engineered tuav nws hauv av, weld tom qab weld, xyoo tom qab xyoo.
