Robotic welding fixture tsim tsis yog hais txog bolting qhov chaw rau lub phaj. Nws yog hais txog kev tshem tawm qhov sib txawv ua ntej tus neeg hlau txawm txav nws thawj axis. Peb tau pom ntau cov kab ntau lawm - tsis yog los ntawm faulty robots los yog hlau tsis zoo - tab sis vim hais tias lub fixture cia qhov chaw hloov 0.12 hli thaum lub sij hawm clamping. Qhov kev sib txawv me me no hla 300 welds, tig lub nominal ± 0.5 hli kam rau ua tus nqi seem tshaj 18%. Precision pib qhov twg hlau ntsib fixture.
Vim li cas "Zoo txaus" Fixtures Fail nyob rau hauv Automation
Phau ntawv welding tolerates tus neeg teb xov tooj adaptation. Ib tug kws welder txawj them nyiaj rau qhov me me txav, kho lub kaum sab xis ntawm lub ya, thiab nyeem thermal distortion zoo li lub cev lus. Cov neeg hlau tsis hloov pauv - lawv rov ua dua. Yog tias koj cov khoom siv hlau vuam tsis muaj qhov chaw rov ua dua, cov khoom sib txuas sib txuas sib txuas, lossis cov nyiaj thermal nthuav dav, koj tsis tuaj yeem ua qhov vuam zoo-koj ua haujlwm tsis sib xws.
Peb niaj hnub soj ntsuam cov khoom siv coj los ntawm Tier-1 automotive lwm tus neeg. Cov ntsiab lus tsis zoo tshaj plaws? Pin-and-bush locators hnav dhau ISO 2768-mK txwv. Caij nplooj ntoos hlav-loaded clamps nrog 22% quab yuam lwj tom qab 4,000 cycles. Lub hauv paus daim hlau warped los ntawm unbalanced tshav kub dissipation - ntsuas txog li 0.35 mm sib txawv nyob rau hauv ib tug 1.2 m ncua. Cov no tsis yog rooj plaub ntug. Lawv yog lub hauv paus ua rau tom qab 63% ntawm thawj tsab xov xwm rov ua haujlwm peb pom hauv cov phiaj xwm tshiab.
Kev ua haujlwm tiag tiag hauv ntiaj teb xav tau ntau dua li kev sib tw CAD. Nws yuav tsum to taub yuav ua li cas txias-kuav los tiag steel expands ntawm 12.5 µm/m·°C piv rau stainless ntawm 17.3 µm/m·°C — thiab tsim qhov chaw zes uas haum rau ob qho tib si tsis qhia parasitic kev nyuaj siab. Nws txhais tau hais tias cov hardened 60 HRC dowel pins hloov tus qauv 45 HRC pins thaum lub voj voog suav ntau tshaj 50,000. Nws txhais tau tias kev txheeb xyuas clamping siab ib square millimeter-tsis yog tag nrho tonnage-siv calibrated load hlwb thaum tsim nyog.
Plaub Txoj Cai Tsim Kev Txhim Kho Tsis Muaj Kev Sib Tham
Txhua qhov kev ntseeg siab robotic welding fixture peb tsim ua raws li cov cai hauv qab no:
Peb-Point nrhiav, Tsis yog Plaub: Over-constraint induces binding. Peb siv kinematic mounting: ob precision-hauv av dowel pins + ib qho chaw tiaj tus, tag nrho cov txheeb xyuas nrog CMM tiv thaiv GD&T callouts - tsis yog qhov loj me. Clamp Force> Thermal Expansion Force: Thaum qhov kub ntawm qhov kub siab tshaj (txog 1,400 ° C ntawm qhov nugget), cov khoom siv hauv paus nthuav dav tuaj yeem tsim 1,200 N ntawm lub zog sab nraud ntawm 300 hli bracket. Peb cov clamps xa ≥2.5 × qhov tsawg kawg nkaus tuav quab yuam, ntsuas dynamically-tsis statically-ntawm 120 ° C ambient. Modular Interface, Tsis Monolithic Tsim: Lub sijhawm hloov pauv tua ROI. Peb koom ua ke cov qauv ISO 841-3 mounting qauv thiab ceev-disconnect coolant kab. Qhov nruab nrab hloov pauv poob los ntawm 92 feeb mus rau qis dua 14 feeb hla 17 tus neeg siv khoom. Weld Spatter Management li Core Function: Spatter tsis yog khib nyiab - nws yog cov kab mob sib kis. Peb embed tooj liab-coated, hloov tau spatter shields ncaj qha rau hauv lub cev clamp thiab nrhiav lawv nyob rau hauv 8 hli ntawm txhua qhov weld cheeb tsam. Cov ntaub ntawv hauv teb qhia tau hais tias qhov no txo qhov hluav taws xob tu ntau zaus los ntawm 70% thiab txuas lub neej siv tau los ntawm 2.3 ×. Kev Xaiv Khoom Siv Li Cas Hloov Txhua Yam
Aluminium fixtures zoo li sleek - tab sis lawv ua tsis tau sai nyob rau hauv high-duty-cycle ib puag ncig. Peb tau taug qab 10,000+ teev ntawm kev ua haujlwm hla peb tsev neeg cov khoom:
Hardened 4140 Hlau (28-32 HRC): Qhov zoo tshaj plaws rau> 200,000-cycle program. Dimensional stability tuav nyob rau hauv ± 0.015 hli tshaj 18 lub hlis - txawm nrog thermal cycling txhua hnub. Stainless hlau 17-4PH (H900): Nyiam rau cov zaub mov qib lossis corrosive ib puag ncig. Khaws qhov chaw qhov tseeb tom qab 5,000 xuab moos ntsev-txhaj tshuaj-tab sis tus nqi 3.2 × ntau dua 4140. Cam khwb cia hlau EN-GJS-600-3: Siv tsuas yog rau cov rooj sib txoos loj loj (> 2.5 m). Dampens kev co zoo dua hlau-tab sis yuav tsum tau 72-teev kev ntxhov siab nyem annealing tom qab machining. Peb yeej tsis qhia cov khoom raws li tus nqi ib leeg. Thaum ib tus neeg thov kom peb hloov ntawm 4140 mus rau txhuas kom txuag tau $ 1,200 rau ib qho kev sib tw, peb tau khiav 3 lub hlis tsav. Qhov tshwm sim: 4.8% nce hauv qhov porosity, 11% siab dua electrode noj, thiab 3.2 ntxiv kev saib xyuas nres ib zaug. Cov "txuag" ploj mus hauv lub lim tiam ob.
Botou Haijun's Fixture Validation Protocol
Peb cov khoom siv thauj khoom nrog cov ntaub ntawv pov thawj-tsis tau cog lus. Txhua unit yuav tsum:
Pre-assembly CMM pov thawj ntawm txhua qhov chaw qhov chaw (ASME B89.1.10M-2018 ua raws) Clamp quab yuam daim duab qhia thoob plaws kev mus ncig ntau yam siv piezoelectric sensor daim phiaj Kev ntsuas kub ntawm lub voj voog: 50 lub voj voog ntawm 20 ° C mus rau 180 ° C, ntsuas qhov chaw drift ntawm txhua qhov huab Ntau lawm-kab qhuav-khiav: 200 lub voj voog sib law liag nrog cov khoom tiag tiag, saib xyuas ntawm laser tshem tawm sensors Qhov no tsis yog over-engineering. Nws tiv thaiv tus nqi $ 247,000 ntawm ib qho kev tsim tawm ib zaug uas tshwm sim los ntawm kev sib tw-induced misalignment. Botou Haijun Hlau Khoom Co., Ltd. tsim robotic welding fixture systems uas ciaj sia-tsis yog ua haujlwm-hauv cov chaw tsim khoom tiag. Peb ua haujlwm los ntawm Botou City, Hebei Xeev, qhov chaw txias-forming metallurgy ntsuas hauv microns, tsis yog millimeters. Peb lub tuam txhab ISO-raws li kev sib koom ua ke stamping, dabtsi yog khoov, vuam, thiab kev ntsuas hauv qab ib lub ru tsev - yog li tsis muaj kev cuam tshuam rau kev ua siab ntev stack-up. Peb xa cov tswv yim engineering hauv peb hnub ua haujlwm. Cov lus hais tuaj txog hauv qab 48 teev. Thiab yog hais tias lub fixture tsis tuav ± 0.02 hli tshaj 10,000 cycles, peb rework nws - tsis muaj kev sib cav.
Vim hais tias precision tsis yog specification. Nws yog qhov sib txawv ntawm qhov uas tus neeg hlau xav tias nws ua - thiab qhov ua tau zoo li cas. Kaw qhov khoob. Pib nrog lub fixture.
