Nangona kunjalo, zisenokungalungeli iijiyometri ezintsonkothileyo okanye iimfuno ze-welding ezichanekileyo. Amandla okubamba kufuneka alawulwe ngononophelo ukuphepha ukonakalisa amacandelo.
Izilungiso zeJig-Type
Izixhobo zodidi lweJig zibonelela ngesisombululo esingqongqo nesichanekileyo kwiijiyometri ezintsonkothileyo. Bahlala bebandakanya izikhonkwane zendawo, i-bushings, kunye nezinye iimpawu zokuqinisekisa indawo echanekileyo yecandelo. Izilungiso zeJig zihlala zibiza kakhulu kwaye zintsonkothile ukwenza kunohlobo lwe-clamp kodwa zibonelela ngokuchaneka okuphezulu kunye nokuphindaphinda. Oku kuchanekileyo kubalulekile kumgangatho we-weld ongaguqukiyo ekufuneni izicelo zeemoto.
Ukulungiswa kweeModyuli
Iimodyuli zibonelela ngokuguquguquka kunye nokuguquguquka. Uyilo lwabo luvumela uhlengahlengiso olulula kunye nokwenza ngokwezifiso ukulungiselela amacandelo ahlukeneyo okanye ulandelelwano lwe-welding. Oku kuziqhelanisa kubalulekile kubavelisi abajongana nokutshintsha rhoqo kwemodeli okanye ukwahluka kwemveliso. Ubume bemodyuli bunciphisa ixesha lokuphumla kwaye lukhawulezise ukulungiswa komgca wemveliso. Nangona kunjalo, utyalo-mali lokuqala kwinkqubo yemodyuli ingaba phezulu.
Iingqwalasela eziphambili kwi-BIW Welding Fixture Design
Ukukhethwa kwezinto
Ukukhethwa kwezinto eziphathekayo BIW izixhobo zokuwelda ibalulekile ekomeleleni, ukuchaneka, kunye nokumelana nokunxiba. Intsimbi ephezulu kunye nentsimbi ephosiweyo zikhetho eziqhelekileyo, ezinikezela ngokugqwesileyo okugqwesileyo kunye nokuchasana ne-deformation phantsi kwemikhosi ephezulu ye-clamping. Ukhetho kufuneka luthathele ingqalelo izinto ezinje nge-weldability kunye nokulula komatshini. Ukukhetha izixhobo ezifanelekileyo kuchaphazela ngokuthe ngqo ubomi bomdlalo kunye neemfuno zokugcinwa. Ukusetyenziswa kwezinto ezisemgangathweni ophezulu kuqinisekisa ukusebenza kwexesha elide kunye nokunciphisa ixesha lokuphumla.
Uyilo lokuVeliswa (DFM)
Ukuphunyezwa kwemithetho-siseko yoYilo lweMveliso (DFM) ibalulekile kwimveliso esebenzayo neyonga imali. Oku kubandakanya ukwenziwa ngcono uyilo lokulungisa ukwenza lula iinkqubo zokwenziwa, ukunciphisa inkcitho yezinto eziphathekayo, kunye nokunciphisa ixesha lokudibanisa. Iingqwalasela ze-DFM kufuneka zibandakanye imiba efana nokukhetha izixhobo, ukufikeleleka kwemathiriyeli, kunye nokulula kokucoca nokugcinwa. Iinkqubo ezisebenzayo ze-DFM zikhokelela ekunciphiseni iindleko zemveliso kunye namaxesha okuguqula ngokukhawuleza.
Ulawulo loMgangatho kunye noLondolozo
Ukuhlolwa rhoqo kunye nokugcinwa kwe BIW izixhobo zokuwelda zibalulekile ekuqinisekiseni umgangatho we-weld ongaguqukiyo kunye nokunciphisa ixesha lokuphumla. Oku kuquka ukujonga ukuguga nokukrazuka, ukuqinisekisa amandla abambekayo afanelekileyo, kunye nokuqinisekisa ukuchaneka kwamalungu okulungiseka. Ukulungiswa okugcinwe kakuhle kuya kuqinisekisa ukuchaneka kwexesha elide kunye nokuthembeka kwenkqubo ye-welding. Iishedyuli zothintelo lolondolozo kufuneka zisekwe kwaye zithotyelwe. Ukujongwa rhoqo komgangatho wezixhobo ngokwazo kubaluleke njengokuhlolwa komgangatho we welds ezivelisayo.
I-Case Study: Ukuphucula i-BIW ye-Welding Fixture yokuphucula ukusebenza kakuhle
Omnye umenzi uye wafumana ukuphucuka okubonakalayo kokungaguquguquki kwe-weld kunye nesantya semveliso ngokufaka endaweni yesistim esidala se-clamp ngenkqubo yeemodyuli.
