Vuam lub rooj jigs tsis yog cov khoom siv-lawv yog quab yuam sib npaug. Nyob rau hauv peb lub khw, peb tau pom cov pab pawg txiav lub voj voog lub sij hawm los ntawm 40% tsuas yog los ntawm kev sib pauv generic clamps rau lub hom phiaj tsim welding rooj jigs. Ib tus neeg siv khoom siv ua liaj ua teb txo qis rov ua haujlwm ntawm 12% mus rau qis dua 2% tom qab hloov los ntawm phau ntawv layout mus rau rov ua dua jig-based fixturing. Qhov ntawd tsis yog kev txhim kho ntxiv. Nws yog dimensional tswj ua lub cev.
Yog vim li cas "Zoo txaus" Fixturing tsis nyob rau hauv tiag Load
Feem ntau cov fabricators pib nrog lub kaum sab xis hlau, C-clamps, thiab sib nqus hauv paus. Lawv ua hauj lwm-txog thaum tshav kub kub distortion kicks nyob rau hauv, kom txog rau thaum lub thib peb ntawm ib tug 50-thooj khiav hloov 0.3 hli, kom txog rau thaum ib tug bracket tsis qaug zog xeem vim weld nkag tau mus txawv tebchaws nyob rau hauv lub batch. Peb tau ntsuas nws: qhov tsis muaj kev ruaj ntseg deflect mus txog 0.8 hli thaum tack vuam ib leeg. Qhov kev txav me me no nthuav tawm mus rau hauv cov flanges misaligned, cov hauv paus tsis sib xws, thiab kev ntxhov siab tsis muaj kev sib tsoo tom qab vuam tuaj yeem kho.
Qhov tseeb fixturing ua peb yam ib txhij: nrhiav, txhawb, thiab txwv. Nrhiav tus pins ntaus datums - tsis kwv yees cov npoo. Kev them nyiaj yug pads phim ib feem contour-tsis tiaj steel daim hlau. Restraint rog tiv thaiv thermal expansion vectors - tsis yog lub ntiajteb txawj nqus xwb. Yog vim li cas welding rooj jigs ua rau ntawm modular T-slot tables outperform ad-hoc setups txhua lub sij hawm: lawv tig variability mus rau repeatability.
Plaub Tsis-Tshaj Tawm hauv Jig Tsim (Tom qab los ntawm 7 Xyoo ntawm Cov Ntaub Ntawv Teb)
Peb tau lees paub txhua qhov kev cai jig tawm tsam plaub yam no-ua ntej txiav thawj phaj:
Thermal Compensation: Lub hauv paus daim hlau siv 12-mm-tuab txias-kuav los tiag-tsis yog 6-mm-vim cov khoom nyias nyias warps sai dua nyob rau hauv arc tshav kub. Peb ntxiv cov qhov nyem nyob rau hauv cov cheeb tsam kub kub kom cia qhov nthuav dav tshwm sim deb ntawm qhov chaw nyob. Load Path Integrity: Txhua lub clamp quab yuam txoj kev ncaj qha mus rau hauv lub rooj cov qauv txheej txheem - tsis yog los ntawm stacked adapters. Ib qho 12-kN pneumatic clamp poob 35% muaj zog quab yuam yog mounted ntawm ob 10-mm spacers. Datum Consistency: Tag nrho cov thawj qhov chaw siv tib lub dav hlau saum npoo. Kev sib xyaw ntawm qhov chaw thiab ntug ntawm qhov chaw ntawm ib feem ua rau muaj qhov yuam kev. Peb tswj hwm "ib tus tswv datum ib axis" hauv txhua qhov kev tshuaj xyuas DFM. Tooling Accessibility: Weld access qhov yog qhov loj kom haum MIG phom - tsis yog "loj txaus." Peb sim nrog lub teeb lub kaum ntse ntse: 30 °, 45 °, thiab 60 ° txoj hauv kev. Yog hais tias lub nozzle ntaus lub jig ntawm 45 °, lub qhov yuav loj los yog offset. Cov no tsis yog cov tswv yim theoretical. Lawv yog hom kev ua tsis tiav peb tau nkag mus hla 1,200+ ntau lawm khiav-los ntawm cov hlau tsis muaj pa tawm mus rau txhuas neeg hlau qhov kawg-effectors.
Thaum Off-the-Shelf Jigs poob luv (Thiab Yuav Ua Li Cas Hloov)
Qee tus yuav sib cav: "Vim li cas ho tsis yuav cov qauv vuam rooj jigs?" Vim tias qhov tiag tiag tsis tshua muaj kev sib tw catalog profiles. Ib tus neeg siv khoom ib zaug xaj tsib qhov zoo ib yam "universal engine mount jigs" - tsuas yog nrhiav tau lawv cov cam khwb cia-aluminium vaj tse muaj qhov sib txawv ntawm qhov sib txawv ± 0.5 ° hla cov khoom siv. jig tuav Part #1 zoo kawg nkaus. Qhov #2–#5 yuav tsum tau shimming, re-torquing, thiab zaum kawg tes-fitting.
Qhov ntawd yog qhov chaw ntsug kev koom ua ke tseem ceeb. Ntawm Botou Haijun Hlau Khoom Co., Ltd., peb tsim, stamp, khoov, thiab weld jigs nyob rau hauv-tsev-tsis muaj lwm tus neeg muag khoom, tsis muaj handoffs. Thaum Tier-1 automotive tsum xav tau jigs rau EV roj teeb tshiab, peb tau xa cov qauv ua haujlwm hauv 11 hnub: CAD qauv → laser-txiav puag phaj → CNC-bent locator caj npab → welded los ua ke → CMM validation. Tsis tos rau machined castings. Tsis muaj kev tiv thaiv los ntawm ntau tus neeg muag khoom.
Peb cov neeg siv khoom tsis them rau "jigs." Lawv them rau thawj-ib feem-txoj cai sib xws-Thiab qhov ntawd tsuas yog tshwm sim thaum fixturing yog engineered raws li ib feem ntawm cov khoom tsim khoom, tsis bolted tom qab.
Tsim Kev Ntseeg, Ib Dimension ntawm Ib Lub Sijhawm
Vuam rooj jigs nthuav tawm qhov tsis muaj zog hauv koj cov txheej txheem-ceev. Yog tias koj qhov chaw yuav tsis nyob tsis tu ncua, jig qhia nws. Yog tias koj cov khoom springback tsis yog qauv, lub jig qhia qhov sib txawv. Lub pob tshab ntawd tsis xis nyob - tab sis tsim nyog.
Ntawm Botou Haijun Hlau Khoom Co., Ltd., peb kho jig tej yaam num xws li kev sib koom ua ke: sib koom GD&T tshuaj xyuas, stamped soj ntsuam cov ntaub ntawv rau txhua qhov chaw tus pin, ntsev tsuag tshuaj ntsuam ntawm zinc-nickel coated clamping nto. Peb tsis xa cov jigs "tiav" - peb xa cov ntaub ntawv rov ua dua. Txhua qhov khoom xa tuaj suav nrog CMM cov ntaub ntawv qhia qhov sib txawv max hla 20 qhov sib law liag. Tsis nruab nrab. Tsis yog cov ntawv nyeem zoo tshaj plaws. Qhov phem tshaj plaws, ntsuas.
Qhov muaj zog tshaj plaws vuam tsis yog ib qho uas muaj cov hlau nplaum tshaj plaws. Nws yog ib qho muab tso rau qhov chaw tsim qauv - txhua lub sijhawm. welding rooj jigs ua kom qhov kev xav tau ua tiav. Thiab thaum koj fixturing ua tau zoo li lub cuab yeej precision - tsis yog qhov chaw - koj tsis txhob sib ntaus sib tua, seem, thiab daim ntawv teev sijhawm. Koj pib shipping kev ntseeg siab.
