Buri cyuma gisobanutse neza ntigitangirana na arc - ahubwo gifite ubuso butimuka. A. ameza yo guhimba ntabwo ibyuma gusa kumaguru. Numufatanyabikorwa ucecetse muri buri teraniro risubirwamo: umusingi ufite kwihanganira gukomera kurenza umuhamagaro wawe wa GD&T, ukurura vibrasiya mbere yuko uhindura fillet, kandi uhindura ubuhanga bwabakozi muburyo buhoraho.
Twarebye amaduka menshi yiruka kugoreka weld gusa tumenye ko intandaro itari iyinjiza ubushyuhe-byari igice cyo kugenda mugihe cyo gufunga. Mu mushinga umwe wibikoresho byubuhinzi umwaka ushize, ikosa ryumukiriya wikurikiranwa ryagereranijwe ± 0.8 mm mumyobo 12. Bazamuye imbunda yabo ya MIG, bongeramo gaze ya purge, ndetse basudira gusudira ibipimo bya pulse. Gukosora? Yongeye gukora ameza yo guhimba hamwe na kinematike yo gushakisha pin, gukomera kwa dowel bushing, hamwe na zeru-gukina toggle clamps. Itandukaniro rya nyuma ryamanutse kuri ± 0.15 mm - muri spec, nta kongera gukora.
Kuki "Imeza gusa" yananiwe munsi yimitwaro-yisi
Imeza ya jig igomba gukora ibintu bitatu icyarimwe: gushakisha, kubuza, no kubaho. Ntabwo bose babikora.
Kubona bisobanura gusubiramo - ntabwo gukubita ahantu hamwe rimwe gusa, ahubwo kubikora inshuro 500 mugihe cyo guhinduranya, guhindagurika k'ubushyuhe, no kwambara ibikoresho. Dukoresha ibyuma bidafite ibyuma byerekana ibyari bifite uburinganire bwa mm 0.01, ntabwo ari plaque. Kubuza bisobanura gukumira dogere esheshatu zubwisanzure - ntabwo ari ugukanda hasi gusa, ahubwo no kurwanya kuzamura, kugoreka, no kunyerera kuruhande mugihe cyo gusudira kwaguka kwinshi. Niyo mpamvu ameza yacu ahuza gusudira-muri T-slot ya gari ya moshi hamwe nimbaraga zipakurura imitwaro-ntabwo ari ibikoresho bya bolt-on. Kurokoka bivuze gufata kalibrasi nyuma ya 3000+ weld pass, ntabwo irokoka urumuri rwa mbere. Turashimangira-gukuraho ibyapa byose byibanze nyuma yo gutunganya no kugenzura ituze hamwe na CMM yohanagura mbere yo gusya hejuru. Simbukira kuri buriwese - kandi wishyura ibicuruzwa, gukora, cyangwa gutinda kubyoherejwe. Twabonye abakiriya basimbuza amadolari 120k ya robot kuko ameza yabo ya jig yagabanutse munsi yumukino wo gusiganwa ku magare. Gukosora imbonerahamwe byatwaye 7% byigiciro cya robo. Kandi yatanzwe muminsi 11.
Ibyo ba injeniyeri bakeneye mubyukuri - ntabwo aribyo udutabo dusezeranya
Bamwe mubatanga urutonde "± 0,05 mm zukuri" batavuze uko ibintu bimeze: ubushyuhe bwicyumba? Nta gushiramo ubushyuhe? Yapakuruwe? Ukuri-kwisi kwukuri guterwa nuburyo imbonerahamwe yitwara mugihe urimo gusudira saa yine za mugitondo, hamwe nubushyuhe bwibidukikije buzunguruka 15 ° C ijoro ryose.
Niyo mpamvu twubaka buri ameza yo guhimba yo kwihanganira ibikorwa:
Ibikoresho shingiro. Sisitemu yo gushiraho. Gucunga ubushyuhe. Modularity: Imigaragarire isanzwe ireka abayikoresha bahinduranya, bongeramo clamps, cyangwa bahuze intego yo guhuza icyerekezo - byose batabanje gucukura umwobo mushya. Ntabwo tugurisha "ameza." Dutanga sisitemu yo guhitamo. Buri gice cyoherejwe na raporo yuzuye ya CMM yerekana uburinganire, kubangikanya, hamwe na gari ya moshi-kuri gari ya moshi - bikurikiza ibipimo bya NIST.
Nta Minimum. Nta Gukeka. Nta Kwiyunga Kubikurikirana
Amatsinda mato ntagomba gusobanura ibikoresho byo mucyiciro cya kabiri. Imodoka imwe yo mu Burayi Tier-1 itanga amamodoka yari ikeneye jigs 14 yihariye - kugirango yemeze prototype kumurongo mushya wa batiri ya EV. Abacuruzi babo ba mbere bavuze ibyumweru 12 kandi basaba ibice 50 byibuze. Twatanze imbonerahamwe 14 yagenzuwe neza, CAD yemewe muminsi 16. Buri gice cyarimo ibitekerezo bya DFM byerekana ibitekerezo, ibyifuzo bikurikirana, hamwe nibikoresho bya EN 10131 DC04 ibyuma bikonje.
Ibi birakora kuko ubushobozi bwacu burahagaritse - ntabwo buringaniye:
Igishushanyo: Mu nzu ya ba injeniyeri ba GD&T basubiramo icyitegererezo cya 3D hamwe nibibazo byo kubangamira ibendera mbere yo kuvuga. Kubaka: Gukata plasma ya CNC, gusudira robotic yububiko, hamwe no gufatisha intoki hejuru - byose munsi yinzu imwe yemewe ISO 9001. Kwemeza: Buri mbonerahamwe ikorerwa ibizamini bikora hamwe nibice byakozwe hamwe na clamp zifatika - ntabwo ari kaliperi gusa. Inkunga: Nyuma yo koherezwa, turagumana amakuru yawe ya CMM, ikarita yo gusudira, hamwe no kwihanganira isesengura ryibihe byo kuvugurura ejo hazaza. Nta outsourcing. Nta ntoki. Oya "tuzagenzura no gukora." Itsinda rimwe gusa - kuva kuri cote kugeza kuri komisiyo.
Intambwe ikurikiraho ntabwo ari ayandi magambo. Ni Porotokole yo Kwemeza.
Mbere yo gusinya kurindi ameza yo guhimba, ibaze: Iza ifite ibyangombwa byubushyuhe bwo gutuza umurongo? Urashobora kugenzura uburinganire bwacyo munsi yumutwaro - utaruhutse gusa? Sisitemu yo gushakisha yateguwe kubice byawe bibi cyane-datum ihinduka-cyangwa ni geometrie gusa?
Botou Haijun Metal Products Co., Ltd. yubaka ameza ya jig aho umugambi wubwubatsi uhura nukuri kububiko. Kohereje sisitemu zirenga 870 zuzuye kuva muri 2019-kubakiriya bo mubudage bubaka umuyaga wa turbine nacelles, mubigo byubuhanga bwikoranabuhanga byo muri Amerika biteranya ama frame yigenga, kubatanga EMS bo mu majyepfo yuburasirazuba bwa Aziya bateranya chassis yubuvuzi. Bose basangiye icyifuzo kimwe: kwihanganira zeru kumwanya ugenda.
Niba inteko yawe itaha isaba gusubirwamo - ntabwo ari ibyiringiro - tangirana n'ukuri kugaragara. Tangira na a ameza yo guhimba injeniyeri yo gufata ubutaka bwayo, gusudira nyuma yo gusudira, umwaka nuwundi.
