Vuam fixture ntxhuav hloov li cas fabricators tuav, nrhiav, thiab rov ua qhov chaw-tsis muaj clamping los ntawm qhov muag, tsis muaj rework ntxiv los ntawm drift. Peb tau pom cov khw txiav lub sijhawm teeb tsa los ntawm 65% tom qab hloov los ntawm kev cai jigs rau modular welding fixture rooj tshuab. Ib tus neeg siv khoom hauv Changzhou welded zoo tib yam chassis thav duab rau peb xyoos siv ib lub phaj phaj thiab cov cuab yeej sib hloov tau - xoom qhov sib txawv ntawm 12,000 units.
Vim li cas repeatability pib ntawm lub rooj - tsis yog welder
Feem ntau cov vuam yuam kev pib ua ntej arc ntaus. Ib feem hloov 0.3 hli thaum clamping. Lub puab tsaig hnav tsis sib xws. Ib qho av saum npoo poob flatness tom qab tsib lub voj voog thermal. Cov no tsis yog "tus neeg ua haujlwm yuam kev." Lawv yog cov kev ua tsis tiav - thiab lawv sib xyaw nrog txhua qhov sib koom ua ke.
Ib qhov tseeb welding fixture rooj daws qhov no ntawm lub hauv paus. Nws tsis yog tsuas yog steel phaj nrog qhov. Nws yog ib qho kev sib koom ua ke anchored rau ISO 2768-mK tolerances, nrog T-slots spaced ntawm meej 50-mm intervals, hardened saum npoo (HRC 58-62), thiab load-bearing muaj peev xwm txheeb xyuas ib DIN 53404. Peb sim txhua lub rooj nyob rau hauv 300% rated static load ua ntej shipping. Qhov ntawd txhais tau hais tias 1,200 kg-rated lub rooj tuav 3,600 kg yam tsis muaj kev ntsuas qhov deflection.
Lub ntiaj teb tsis ua haujlwm tiag tiag tshwm sim thaum cov neeg siv tsis quav ntsej mounting rigidity. Bolting lub rooj fixture rau nyias 6-mm steel ncej? Cia siab tias 0.18 hli sag hauv qab 800 kg loading. Mount nws mus rau 25-mm structural steel puag nrog plaub M16 thauj tog rau nkoj bolts torqued rau 190 N·m? Deflection poob rau 0.02 hli. Lub rooj tsis dag - tus qauv txhawb nqa ua.
Modular vs. tsau: Qhov twg xa ROI hauv 90 hnub?
Qee qhov kev sib cav tsim kho cov rooj sib tw modular ntawm qhov tseeb. Tab sis peb tau taug qab 17 qhov chaw ua haujlwm nruab nrab ntawm 18 lub hlis. Cov neeg siv cov jigs ruaj khov nruab nrab yog $ 4,200 nyob rau hauv ib xyoos ib zaug downtime ib lub chaw nres tsheb - feem ntau los ntawm kev rov tsim kho qeeb thiab kev cia khoom sib tsoo. Modular welding fixture rooj cov neeg siv tau siv $ 1,100 rau kev hloov kho tshiab txhua xyoo thiab rov qab 11 teev / lub lim tiam hauv kev ua haujlwm thiab lub sijhawm teeb tsa.
Qhov txawv yog nyob rau hauv adaptability. Cov txheej txheem modular siv cov txheej txheem txheem: profile rails (20 × 20 mm, 30 × 30 mm, lossis 40 × 40 mm aluminium extrusions), locking clamps nrog ± 0.02 mm repeatability, thiab ceev-hloov locators nrog hardened steel pins (Ø6 mm, Ø8 mm, Ø10 mm). Koj tsim kho qhov tshiab nyob rau hauv 90 feeb - tsis yog peb hnub.
Nov yog dab tsi ua haujlwm - thiab dab tsi tsis ua:
- Ua haujlwm: Siv Ø10 mm dowel pins rau thawj qhov chaw; ua ke T-slot txiv ntseej nrog qis-profile cap screws (M6 × 12 mm) kom tsis txhob cuam tshuam nrog cov neeg hlau teeb pom kev
- Ua tsis tiav: Stacking peb txheej ntawm daim hlau adapter tsis recalibrating Z-axis datum; siv cov yas-tipped clamps ntawm kub dov steel saum 120 ° C
- Saib tsis taus: Grounding txuas ntxiv-txhua qhov clamp yuav tsum tuav ≤0.1 Ω tsis kam rau lub rooj hauv av. Peb ntsuas qhov no nrog Fluke 1625-2 ua ntej commissioning
Botou Haijun Hlau Khoom Co., Ltd. tsim nws cov ntxhuav nyob ib ncig ntawm cov teb no. Txij li xyoo 2010, peb cov engineers tau teeb tsa ntau dua 2,300 units thoob plaws cov chaw tsim khoom tsheb, cov khoom siv ua liaj ua teb, thiab cov chaw kho tsheb ciav hlau-tag nrho hauv Botou City, Hebei Xeev, qhov chaw kub ntawm 15 ° C mus rau 42 ° C txhua xyoo. Thermal stability tsis yog xaiv tau. Nws tau tsim rau hauv qhov kev ntxhov siab-txhim kho cam khwb cia hlau puag thiab them nyiaj rau qhov geometry.
Kev teeb tsa tsis yog ntsaws-thiab-ua si - thiab qhov ntawd yog qhov taw tes
Koj xav tau qib pob zeb, tsis yog epoxy-dusted khw hauv pem teb. Yam tsawg kawg nkaus slab thickness: 150 mm. Rebar sib nrug: ≤200mm nruab nrab-rau-center. Anchor bolt qhov tob: ≥180 mm rau hauv cov pob zeb kho (tsis ntsuab ncuav). Hla ib kauj ruam, thiab koj 0.05 mm kam rau ua 0.4 mm nyob rau hauv rau lub hlis.
Peb yuav tsum tau laser alignment thaum lub sij hawm kawg installation-siv ib tug Leica Geosystems LS15 teb laser, tsis yog ib tug ntsuj plig. Vim li cas? Vim lub ntiajteb txawj nqus tsis mob siab rau koj lub siab ntev. A 0.1 ° qaij hla lub rooj 2,000 hli tsim 3.5 hli qhov siab hloov pauv ntawm qhov kawg. Qhov ntawd yog txaus rau misalign tus neeg hlau seam tracker.
Lub zog thiab grounding tseem ceeb heev. Vuam fixture rooj yuav tsum khi rau hauv tib lub earthing system raws li lub hwj chim qhov chaw. Tsis muaj rods. Tsis muaj kev sib koom ua ke. Ib txoj kev txuas mus ntxiv - txheeb xyuas nrog lub megohmmeter ntawm 500 V DC. Peb sau txhua qhov kev tawm tsam nyeem hauv daim ntawv tshaj tawm commissioning. Cov neeg siv khoom uas hla qhov no pom kev hnav ntxov ntxov ntawm cov lus qhia tawm thiab qhov tsis zoo ntawm CNC qhov chaw.
Botou Haijun muab kev txhawb nqa tag nrho-tsis yog phau ntawv qhia xwb. Peb cov kws tshaj lij nqa tau CMM caj npab los xyuas kom meej qhov flatness tom qab kev teeb tsa. Flatness kam rau ua yog ≤0.08 hli tshaj 1,000 × 1,000 mm cheeb tsam. Yog tias nws ua tsis tau, peb kho shims los yog rov tho anchors - ntawm qhov chaw.
Precision tsis yog ib qho feature. Nws yog lub hauv paus.
A welding fixture rooj tsis ua kom welds muaj zog. Nws ua rau lawv twv tau. Nws hloov qhov sib txawv ntawm qhov sib txawv rau hauv kev tswj hwm qhov sib txawv - tsis yog rho npe. Cov khw muag khoom uas kho nws raws li kev tsim kho vaj tse-tsis yog khoom siv-pom cov nqi poob qis los ntawm 4.7% mus rau 0.9% hauv qis dua plaub lub hlis. Lawv tsis nug "Peb puas tau txais nws lawm?" thiab pib nug "Peb tuaj yeem ntsuas tau nrawm npaum li cas?"
Qhov kev hloov pauv no pib nrog kev xaiv cov khoom siv (kev ntxhov siab-txo EN-GJL-250 cam khwb cia hlau, tsis yog welded steel), txuas ntxiv nrog kev ntsuas ntsuas-qib machining (CNC-milled slots tuav mus rau ± 0.015 hli), thiab xaus nrog lub ntiaj teb validation-tsis yog lab specs. Botou Haijun Hlau Khoom Co., Ltd. tsim rau lub khw hauv pem teb, tsis yog chav ua yeeb yam. Txhua lub rooj ships nrog ib daim ntawv pov thawj calibration, tag nrho torque specs, thiab thermal expansion cov ntaub ntawv rau koj cheeb tsam huab cua.
Lub neej yav tom ntej belongs rau cov tuam txhab uas txuas ib zaug - thiab tau txais nws txoj cai. Tsis yog cov uas welding, ntsuas, grind, re-weld, thiab kev cia siab. Koj lub rooj zaum tom ntej yuav tsum tsis txhob tuav cov khoom. Nws yuav tsum tau lav qhov tshwm sim.
