Gushushanya a Ikizamini cyo gusudira ntabwo ari uguhindura ibice hamwe no kwizera ibisubizo bihamye. Nukwubaka kwagura umubiri mubyifuzo byawe bya injeniyeri-aho buri buso, pin, nimbaraga zifata bihindura muburyo bwiza bwo gusudira gusubirwamo, guhagarara neza, no kwigirira ikizere. Muri Botou Haijun Metal Products Co., Ltd., twubatse ibicuruzwa birenga 270 ibizamini byo gusudira kubatanga ibinyabiziga bya Tier-1, ibikoresho byubuhinzi OEM, hamwe ninganda zikoresha inganda. Muri buri kintu cyose, kunanirwa gukemura ibyingenzi byashushanyije byatumye habaho kimwe cyangwa byinshi muribi bisubizo: kudoda neza, guswera ibinyoma / gutsindwa gusomwa mugihe cyo kwemeza, cyangwa gukora ibintu bihenze nyuma yo gutangiza umusaruro.
Shira igice - Ntukifate gusa
Amakipe menshi atangirana no gufata ingamba-ariko ibyo birasubira inyuma. Ubwa mbere, sobanura gahunda ya datum ukoresheje igice cyimikorere yibice: gushiraho flange, guhuza umuyobozi, cyangwa umwobo ukomeye ugena uko ibice bihuye mukiterane cyanyuma. Dukoresha ingingo eshatu ziri kuri datum zibanze, ntizigera zine - kuko ingingo enye zitera kugoreka mubyuma bito. Kubisanzwe bisanzwe bikozwe muri mm 2,2 mm ibyuma bikonje bikonje, turerekana pin ya dowel ikomye hamwe na ± 0.005 mm yihanganira diameter, kanda-shyira mubihuru byubutaka byicaye mumashanyarazi ya aluminium 6061-T6. Kuki aluminium? Imashini isukuye, igabanya kunyeganyega mugihe cyo gusudira robot, kandi ipima 60% ugereranije nicyuma kubakoresha. Twirinda ibyuma bikozwe mucyuma keretse niba ubushyuhe bwumuriro busabwa kugirango bipimishe cyane-ubwitonzi bwabwo bushobora kuvunika mikoro hafi y’imyobo ikozwe nyuma yizuba ryinshi.
Igenzura Gukura Ubushyuhe-Mbere ya Arc Yambere
Gusudira bitanga ubushyuhe bwaho kugeza kuri 1500 ° C. Izo mbaraga ntizishira-zirimuka. Utagenzuwe, irwanya ibice byabigenewe, ihindura imyanya ya pin kugeza kuri mm 0.08, kandi itesha agaciro ibipimo byose byakurikiyeho. Igisubizo cyacu: stratégies y'umuringa ushyizwemo muri weld yegeranye. Amashanyarazi yumuringa (401 W / m · K) akuramo ubushyuhe inshuro eshanu kurusha aluminium. Twashyizemo umuringa wa OFHC munsi yumutwe weld, ushyizwemo imigozi ya M4 hanyuma tugatandukana muburyo bukuru dukoresheje 0.5 mm PTFE shim. Ibi ntabwo ari theoretical-twapimye 32% yo munsi yubushyuhe bwo gutwarwa hejuru yikizamini cya 120 cyikigereranyo cyihangana na aluminiyumu yose. Bonus: imiterere yumuringa itari magnetique irinda arc guterana mugihe TIG yo kwemeza ikora.
Wubake Kugenzura-Ntabwo Gukoresha Gusa
A Ikizamini cyo gusudira igomba kwerekana ukuri kwayo. Igishushanyo cyose kirimo ibyubatswe byubugenzuzi: igorofa yerekana neza (Ra ≤ 0.4 µm), intego ya CMM igera kumurongo wibanze kuri GD&T ihamagarwa, hamwe na baribasi ya kalibrasi ikurwaho ikurikije ibipimo bya NIST. Umukiriya umwe yashimangiye ko "nta mwobo wongeyeho" - bityo twatunganije Ø6.35 mm z'uburebure bwa sphericale mu buso bwaho. Aba bemera stili ya CMM idafite adapteri kandi bakabaho 10,000+ yo kugenzura. Twinjizamo kandi uburyo bwihuse bwo kurekura hejuru yimbere ya gage imbere, tureka abashinzwe kugenzura uburebure bwaho mumasegonda 90 - ntabwo ari iminota 20 gusenya inteko yose. Niba udashobora gupima ubudahemuka bwa fixture kurenza uko ugenzura igice, wizeye amahirwe, ntabwo ari data.
Huza Ibikoresho Bikomeye Mubikorwa byawe-Ntabwo Bije yawe
Rigidity ntabwo ari mubyimbye-ni mugihe cyo gukwirakwiza inertia. Icyuma cya mm 30 cyibyuma bisa nkibikomeye kugeza igihe wongeyeho mm 120 ya cantilevered ukuboko kugirango ubone robot. Noneho deflection ikubita mm 0,12 munsi ya 45 N yingufu zo gusudira. Igisubizo cyacu: kubaka Hybrid. Shingiro shingiro = mm 25 z'ubugari 7075-T6 aluminium (imbaraga-z-uburemere). Inzira zikomeye za gari ya moshi = zifatanije ibyuma bitagira ibyuma 304 (umusaruro utanga 505 MPa). Umurongo wububiko ukoresha epoxy yo mu kirere hamwe na 0,05 mm igenzurwa-bigenzurwa hakoreshejwe ultrasonic pulse-echo scanning. Ibi bitanga 2,3 × hejuru ya torsional gukomera kurenza aluminium monolithic kuri 18% munsi yuburemere. Twemeje buri gishushanyo hamwe nisesengura ryuburyo bwa FEA bugamije inshuro ya mbere karemano> 120 Hz - hejuru yimashini isanzwe yo gusudira. Nta resonance. Nta drift. Nta rwitwazo.
Buri Ikizamini cyo gusudira dutanga amato hamwe na pake yuzuye ya metrology: nkuko yubatswe na raporo ya CMM, umurongo wa drift curve, hamwe nubushakashatsi bwisubiramo mubakozi batatu na sisitemu ebyiri. Kuberako ubusobanuro atari urupapuro rwihariye-nicyo kirokoka gukoreshwa kwisi. Botou Haijun Metal Products Co., Ltd yubaka ibikoresho bya injeniyeri bizera mugihe ibicuruzwa bisakaye birenga $ 1200 kuri cluster mbi. Niba ubungubu Ikizamini cyo gusudira bisaba kwisubiramo buri munsi cyangwa kunanirwa kugenzura GD&T nyuma yinzinguzingo 500, inenge ntabwo iri mubikorwa byawe-iri mumusingi. Tangirira aho.
