Vuam fixtures tuav qhov chaw nyob rau hauv qhov chaw - tsis muaj kev xav ntau, tsis muaj rework ntxiv. Ntawm Botou Haijun Hlau Khoom Co., Ltd., peb tau tsim ntau tshaj 1,200 kev cai vuam fixture Cov tshuab rau cov chaw muag khoom tsheb, cov khoom siv ua liaj ua teb OEMs, thiab cov khoom siv hluav taws xob muaj kev sib koom ua ke. Feem ntau ua tsis tau los ntawm kev vuam tsis zoo, tab sis los ntawm kev tsim kho qhov tsis zoo: cov ntsiab lus tsis zoo ntawm cov ntsiab lus tsis zoo, tsis muaj kev tswj xyuas thermal distortion, lossis clamping uas npog qhov txawv ntawm qhov sib txawv. Peb kho qhov ntawd - tsis yog nrog txoj kev xav, tab sis nrog lub khw hauv pem teb validation.
Anchor Txhua Fixture rau Tiag Tiag Geometry - Tsis yog CAD Assumpions
Ib tus neeg siv khoom xa tuaj rau peb lub rooj sib dhos sib dhos nrog peb qhov "zoo tagnrho" qhov cim ua datums. Lawv thawj qhov khoom siv dowel pins hauv cov qhov. Tsis pub dhau 48 teev ntawm kev tsim tawm, weld distortion thawb lub qhov thib peb 0.32 hli tawm ntawm spec - txaus los thaiv kev sib dhos zaum kawg. Vim li cas? Daim duab qhia qhov zoo meej; Kev muaj tiag xa tawm ± 0.15 hli txoj hauj lwm kam rau ua los ntawm stamping ua ntej. Peb cov kev daws teeb meem: hloov cov thawj datum mus rau qhov chaw stamped flange, siv lub zes hauv av kom pom qhov tsim ntawm ntug, thiab cia lub qhov ntab thaum clamping. Qhov tshwm sim? Thawj-pass yield dhia los ntawm 68% mus rau 99.4%. Fixtures yuav tsum ua raws li qhov chaw * tiag tiag tuaj txog *, tsis yog lawv kos li cas. Ib txwm txheeb xyuas cov khoom tuaj ntawm GD&T tawm tsam koj qhov kev teeb tsa kev teeb tsa-ua ntej txiav hlau.
Tswj Thaum tshav kub kub-los yog Cia Nws Tswj Koj
Aluminium subassemblies warp sai dua hlau. Ib tus neeg siv khoom siv tshuab ua liaj ua teb nyob sab Europe xav tau kev sib tw rau 12-point TIG vuam ntawm 6061-T6 chassis bracket. Lawv tus qauv tsim yog siv cov hlau nplaum uas muaj kev sib cuag nrog tag nrho saum npoo. Weld kub soaked rau hauv lub fixture, ces rov qab mus rau hauv ib feem ntawm passes-ua rau cumulative angular drift mus txog 1.8 °. Peb hloov kev sib txuas mus tas li nrog ntu, cua-gapped aluminium pads (6061-T6, tib CTE raws li ib feem) thiab ntxiv tooj liab kub dab dej ntawm cov chaw kub kub. Thermal huab hwm coj poob 40%; interpass kub nyob rau hauv 120 ° C. Distortion poob qis dua 0.1 hli hla tag nrho 420-mm ntev. Yog tias koj cov khoom yog aluminium lossis nyias-gauge stainless, kho lub fixture raws li kev tswj kom sov - tsis yog ib tug tuav.
Clamp qhov twg nws tseem ceeb - Tsis yog qhov twg nws yooj yim
Peb taug qab clamping quab yuam qhov chaw ntawm txhua qhov kev tsim kho. Xyoo tas los, 37% ntawm cov neeg siv khoom qhia txog cov teeb meem haum rau clamping-induced elastic deformation. Ib qho kev ua yuam kev: clamping ncaj qha rau ntawm nyias-walled seem ua ntej vuam cov pob qij txha nyob ze. Lub clamp compresses phab ntsa, npog qhov sib txawv-tab sis tso tawm tom qab vuam, nthuav tawm cov kauj ruam 0.5-mm. Peb txoj cai: clamp nkaus xwb ntawm cov yam ntxwv nruj-khoov flanges, cov hlua txuas ntxiv, los yog cov ntaub qhwv lub tshuab-thiab ib txwm offset clamps ≥3 × cov khoom tuab ntawm qhov chaw weld. Rau cov ntawv hlau hauv qab 2 hli tuab, peb ntxiv lub caij nplooj ntoos hlav-loaded locators uas siv ≤150 N quab yuam-tsuas yog txaus tuav, tsis deform. Tsis txhob xav tias "tighter yog zoo dua." Ntsuas deflection nrog lub dial taw qhia thaum clamp-down. Yog tias nws txav ntau tshaj 0.05 hli, rov tsim kho qhov clamp taw tes.
Tsim rau Kev Pabcuam - Tsis yog Kev Sib Koom Tes xwb
Ib qho khoom siv nyob ntev tshaj li ib qho khoom siv. Txawm li cas los xij, 62% ntawm cov khoom siv kho dua tshiab tuaj txog nrog cov xov stripped, khoov qhov chaw pins, lossis cov kab pneumatic corroded - tag nrho los ntawm cov khoom siv tsis tau thiab tsis muaj kev saib xyuas. Peb cov qauv tam sim no suav nrog: ceev-tso cam levers es tsis txhob ntawm hex bolts, hardened stainless hlau hnav pads hloov tau nyob rau hauv 90 vib nas this, thiab modular puag daim hlau nrog standardized M8 tapped qhov spaced txhua txhua 25 hli. Peb kuj embed RFID cim npe nyob rau hauv txhua lub hauv paus fixture-scanned ntawm kab nkag mus pib-load qhov tseeb weld program thiab torque specs. Lub sijhawm poob rau ib qho kev hloov pauv poob los ntawm 22 feeb mus rau 3.4 feeb thoob plaws peb cov neeg siv khoom. Yog tias koj tsis tuaj yeem ntxuav, tshuaj xyuas, lossis hloov cov khoom siv hauv qab ob feeb, nws tsis nyob hauv qhov khoom siv.
Zoo heev vuam fixture kev tsim qauv pib nrog kev txo hwj chim: hwm qhov kev hloov pauv, hwm tus cwj pwm thermal, thiab ua haujlwm rau tus neeg teb xov tooj - tsis yog kos duab. Ntawm Botou Haijun Hlau Khoom Co., Ltd., peb tsis muag fixtures. Peb xa rov ua dua- ntsuas hauv microns, validated nyob rau hauv ntau lawm, thiab guaranteed sau ntawv. Txhua qhov khoom siv yog peb daim ntawv pov thawj ISO 9001-certified soj ntsuam, tag nrho GD&T traceability, thiab ib tug 24-lub hlis cov qauv warranty. Vim hais tias precision tsis yog ib tug feature. Nws yog lub hauv paus.
