Ibisobanuro urupapuro rwo guhimba ibyuma ntabwo ari umurimo wakazi gusa-ni ishingiro ryumubiri ryo kugenzura ibipimo, gusubiramo, no kwizerana kubakoresha. Twarebye injeniyeri zisubiramo selile zose zibyara umusaruro kuko ameza yabo yagabanutse munsi yumukino wo gusiganwa ku magare. Twabonye abakora kunama bahagarara hagati yizuba kugirango bagabanye icyuho cya mm 0,15 - gusa twabonye ko icyabiteye ari ukuringaniza kumeza kurenga ± 0.2 mm hejuru ya mm 1200. Mu kwihanganira urupapuro rwakazi rukora, imbonerahamwe niho geometrie itangirira.
Botou Haijun Metal Products Co., Ltd yubaka ibice byabatanga ibinyabiziga bya Tier-1 banga ibice bifite kwihanganira ibicuruzwa birenga ± 0,12 mm. Kugira ngo ibyo bishoboke, buri kimenyetso cya prototype, buri nzu ishushanyije yimbitse, inzu yose isudira itangirira hejuru yubushakashatsi bwakozwe kugirango butajegajega - ntabwo byoroshye. Ibyo bivuze ko ibyuma bikozwe mu byuma bifite imyaka 30+ yo gusaza bitagabanije gusaza, ntabwo ibyuma bisudira bikoreshwa na mikoro nyuma yo kwikorera imitwaro inshuro nyinshi. Bisobanura ubutaka bwa granite cyangwa ibyuma bikomye hejuru hamwe nuburinganire bwemejwe na ISO 10791-7 Icyiciro cya 4 (≤0.015 mm / m), byagenzuwe hakoreshejwe laser interferometrie - ntabwo ari ibimenyetso byerekana wenyine. Icy'ingenzi cyane, bivuze kwinjiza imbonerahamwe mubikorwa byuzuye: CNC ikanda feri ihagaze, ingingo za CMM zo kugenzura zubatswe hejuru, hamwe na T-slot ishusho ihujwe na sisitemu yo guhuza imashini - ntabwo yongeweho nkigitekerezo.
Bamwe bashobora kuvuga ko imbonerahamwe ya $ 2000 modular ikemura ikibazo kimwe na $ 12,000. Ariko mubikorwa-byukuri byoherejwe, ibyo bitekerezo birananirana kubintu bitatu bikomeye. Ubwa mbere, gutwarwa nubushyuhe: ameza ya aluminiyumu yoroheje yagura 2,3 × byihuse kuruta ibyuma. Guhindura ibidukikije 5 ° C mugihe cyo gushiraho mugitondo birashobora gutera 0,08 mm ikosa ryumwanya hejuru ya mm 1.000 - bihagije kugirango uhuze imiterere yimyobo yo gusudira robot. Icya kabiri, kugabura imizigo: imbonerahamwe isanzwe ntigaragaza neza gutandukana kwingana munsi ya 500 kg. Twapimye mm 0.32 mm sag mubice byinjira-murwego mugihe kimwe icyarimwe cyo gufatira hamwe-kwimura amakosa muburyo bugoramye. Icya gatatu, ubunyangamugayo bwa interineti: ibyapa byerekana ibikoresho akenshi bibura dowel-pin, kureka guhuza bikagenda hagati yimikorere. I Haijun, ameza yose yakozwe akoresha amaboko akomeye ya dowel hamwe na ≤0.005 mm bore-to-pin clearance - kandi isahani yose yashizwe kuri CMM mbere yo kurekurwa.
Niki gitandukanya ubuso bukora nukuri urupapuro rwo guhimba ibyuma iramanuka mubushobozi bune butaganirwaho:
Kugumana ibibyimba munsi yumuriro nubukanishi: Byagenzuwe kuri 25 ° C ± 1 ° C, hanyuma bigenzurwa nyuma yamasaha 8 yumuyaga wa 60 ° C hamwe na 300 kg byagabanijwe Sisitemu yo guhuza ibipimo: Embedded M8 threaded holes on 100 mm grids, with positional accuracy traceable to NIST standards Gucunga imbaraga. Ibyiringiro byo guhuza ibikoresho. Ntabwo tugurisha ameza nkibintu byihariye. Twabashyize mubikorwa byubwubatsi. Mugihe umukiriya w’ibikoresho by’ubuhinzi by’i Burayi yari akeneye gusubirwamo mu bikorwa 14 byunamye ku murongo umwe wa chassis, twashizeho ameza ahindura uburebure bwa zone ebyiri - igice kimwe gifunze kuri mm 920 kugira ngo kibe intoki, ikindi kuri mm 850 zo gupakira robot - byombi dusangira indege imwe ya datum. Iyo imashini yo muri Amerika y'Amajyaruguru ikomatanya byasabye zeru gukora ku byapa byashyizweho na lazeri, twatanze ameza afite impande zabanjirije imashini zahujwe n'ubugari bwa fibre-laser (± 0.02 mm). Ibi ntabwo ari ibintu byihariye. Nuburyo bwo kubazwa bwahinduwe mubyuma na granite.
Reba imbere: Igisekuru kizaza cya urupapuro rwo guhimba ibyuma sisitemu ntizifata ibice gusa-bazabipima. Laboratwari ya R&D ya Haijun ubu irimo kwemeza ibipimo byashyizwemo hamwe na sensor capacitif de sensor igaburira amakuru nyayo yibintu kuri sisitemu ya MES. Ntabwo ari agashya, ariko nkugufunga-gufunga kugenzura kwinjiza: niba kwaguka kwumuriro bihindura Y-axis datum kuri 0,03 mm, feri yamakuru ya CNC yishyura byikora. Urwo rwego rwo kwishyira hamwe rukora gusa iyo imbonerahamwe ihagaritse kuba ibikoresho hanyuma igahinduka igice cyubwubatsi bwiza. Ku matsinda yubaka ibice aho ± 0,05 mm igena gutsindwa kwumurima - cyangwa aho 95% mugihe cyo gutanga kugihe cyatsindiye kubanza kwiruka-imbonerahamwe ntabwo ari yo ntangiriro. Ni garanti yo guceceka.
