Lipoti lamoyo: Kuphimba kwa laser pakhoma lamkati la dzenje la pini la pulaneti, kuwonetsa luso lokonzanso mafakitale

Nthawi ya 7:30 koloko m'mawa, gulu lathu laukadaulo linadutsa pa konkire yonyowa ya fakitaleyo ndipo linayima patsogolo pa malo ogwirira ntchito olemera a kasitomala. Lero, tinali kuchita cladding ya laser pakhoma lamkati la dzenje la pini kuti tipeze gawo lofunika kwambiri la zidazo—chimango cha mapulaneti.

Mpweya wa m'chipinda chogwirira ntchito unali ndi fungo losiyana la madzi odulira zitsulo ndi mafuta a injini, pomwe zingwe za crane zinali zitapachikidwa pamwamba pang'onopang'ono. "Wodwala" wathu—gawo la mapulaneti lolemera matani angapo—anali atayeretsedwa mosamala ndikuyikidwa bwino pa nsanja yayikulu yogwirira ntchito. Monga chimphona chopanda phokoso, makoma ake amkati anali ndi mabowo owonongeka omwe anali otseguka kwambiri, "mabala" omwe tinkafuna kuwachiza molondola lero.

Kufufuza pamalopo ndi "kukonzekera opaleshoni isanachitike"

Mainjiniya Wang wochokera kumbali ya kasitomala anatiyandikira. Pamene ankagwirana chanza, kuuma ndi mphamvu zomwe zinali m'dzanja lake zinali zomveka. Popanda zochitika zapadera, analoza mwachindunji dzenje lalikulu kwambiri la bearing bushing: "Ili lawonongeka ndi 0.8mm, zomwe zinapangitsa kuti phokoso likhale losazolowereka mu gawo lonse la magiya. Ngati tipitiliza kuligwiritsa ntchito, lidzathetsedwa." Kamvekedwe kake kanali ndi ululu wa gawo lofunika kwambiri lomwe likuyandikira kulephera komanso kuyembekezera njira yathu yatsopano.

Ndinagwada pansi ndikulowetsa tochi m'dzenje. Kumene kuwala kunadutsa njira yake, ndinkatha kuona bwino mikwingwirima yocheperako komanso kupotoka pang'ono kwa khoma lamkati chifukwa cha kuwonongeka kwa microscopic. Chimango cha mapulaneti chinali chachikulu, koma vuto linali pa kulondola kwa malo amkati omwe amayesedwa mu ma micrometer—monga kujambula mapangidwe ovuta pabwalo la basketball, kufuna kulondola kwathunthu komanso kukhazikika. "Musadandaule, Injiniya Wang. Kuphimba kwa laser kunapangidwira cholinga ichi," ndinatero, ndikuyimirira kuti ndikhazikitse "tebulo lathu logwirira ntchito."

Potsegula bokosi la zidazo panaonekera gawo lalikulu—mutu wamkati wodzazidwa ndi ufa wa laser wopangidwa ndi khoma. Kapangidwe kake kowonda, koyenera opaleshoni kanafanana ndi chida cholondola chomwe chinkayenera kugwira ntchito mkati mwa chimango cha pulaneti. Pamene mnzake Xiao Zhang anayambitsa dongosolo lolumikizidwa, laser yooneka ngati sikweya inatulutsa phokoso lotsika pamene chophimba cha kabati yowongolera chinkawala ndi magawo osinthasintha. Tinalumikiza mapaipi ozizira mwadongosolo, tinayika makatani a mpweya woteteza coaxial, tinakonza njira zowunikira, ndikukonza bwino chodyetsa ufa—gawo lililonse linkachitika mosamala kwambiri. Mpweya unadzazidwa ndi phokoso la mafani ndi malamulo athu achidule.

Njira yopangira cladding: kuvina kwa kuwala ndi ufa

"Njira" yeniyeni inayamba. Motsogozedwa ndi njira zomwe zinakonzedwa kale, mutu wophimba unalowetsedwa mofatsa mu dzenje la pin la pulaneti. Mkati mwa kuya kwa mdima kwa chibowo, kuwala kwa laser komwe sikunawonekere ndi maso ndi maso konse kunayang'ana bwino pakhoma lamkati, nthawi yomweyo kupanga dziwe losungunuka la microscopic. Pafupifupi nthawi yomweyo, mpweya wonyamulira unatulutsa ufa wa alloy wokhala ndi nickel wabwino kwambiri kudzera mu nozzle ya mutu wophimba, ndikupopera mofanana ngati utsi ndi fumbi zomwe zinapereka zinthuzo ku dziwe losungunuka.

Mwamsangamsanga, ufa ndi chitsulo choyambira zinasungunuka mofulumira, kusakanikirana, ndi kulimba chifukwa cha mphamvu yaikulu ya laser. Kudzera pawindo lowonera, dziwe laling'ono losungunuka linawala ndi kuwala koyera kowala, likupita patsogolo pang'onopang'ono kupanga chophimba cholimba, chosalala, komanso cholumikizidwa ndi zitsulo kumbuyo kwake. Chithunzichi chinali ngati kugwiritsa ntchito kuwala ngati burashi kujambula netiweki yatsopano yachitsulo mkati mwa chitsulocho.

"Kuthamanga kwa ufa kumakhala kokhazikika, mphamvu ya laser imakhala mkati mwa magawo abwinobwino, ndipo dziwe losungunuka limasunga mawonekedwe abwino." Xiao Zhang anayang'ana pazenera loyang'anira, akupereka zosintha zenizeni pa 'zizindikiro za moyo'. Ndinayima pafupi ndikulemba chizindikiro chilichonse, ndikuonetsetsa kuti mphindi iliyonse ya 'opaleshoni yocheperako' iyi ikulamulidwa. Mainjiniya angapo achichepere ochokera kumbali ya kasitomala adasonkhana mozungulira, maso awo odabwitsa akuyang'ana pamalo otentha omwe akuyenda pazenera pamene akunong'onezana. Mainjiniya Wang anaima ndi manja ake atapinda, nkhope yake pang'onopang'ono ikuchepa kuchoka pa mphamvu yokoka kupita ku khalidwe lomasuka kwambiri.

Luso ndi kudzipereka

Ntchito yonse yophimba denga inatenga pafupifupi maola anayi. Pamene mutu wophimba denga unachoka pang'onopang'ono kuchokera pa dzenje lomaliza, tinazimitsa zida ndipo malo ogwirira ntchito anakhala chete. Koma ntchitoyo sinathe. Gawo lofunika kwambiri linali kuwunika.

Ndinatenga tochi ndi endoscope, ndikuziyika m'bowo. Pansi pa kuunikira, chophimba chatsopanocho chinali ndi kuwala kofanana kwachitsulo, kofanana ndi "shati yatsopano" yokonzedwa bwino yolumikizidwa bwino pakhoma lamkati lomwe lawonongeka. Oyesa kukhwima konyamulika adatsimikizira kuti mtengo wa Ra uli pansi pa 0.8μm, pomwe miyeso ya makulidwe ambiri pogwiritsa ntchito gauge idawonetsa makulidwe ofanana pamwamba ponse, ndikukwaniritsa zonse zomwe zafotokozedwa muzojambula zaukadaulo za 0.5±0.05mm. "Injiniya Wang, monga mukuonera," ndidapereka deta yoyezera, "chophimba ndi gawo lapansi zimagwirizanitsidwa ndi zitsulo, ndipo mphamvu zimaposa ngakhale zinthu zoyambira. Ponena za vuto la kusintha kwa kutentha lomwe mukuda nkhawa nalo kwambiri, kuwongolera kwathu njira kumatsimikizira kuti kusintha konse kumakhalabe pansi pa 0.03mm. Izi zimachotsa kufunikira kwa makina olemera, kulola kusonkhana mwachindunji pambuyo popera molondola."

A Wang adatenga lipotilo, akuyang'anitsitsa bwino kwambiri mayeso onse asanayang'ane endoscope kwa nthawi yayitali. Pomaliza adawongoka, nkhope yake ikusweka ngati kumwetulira koyamba kwa tsikulo: "Zabwino kwambiri! Zotsatirazi zaposa zonse zomwe tikuyembekezera. 'Msana' wathu wabwezeretsedwanso kwathunthu - udzakhalapo nthawi ina yonse yogwira ntchito!" Mawu awa adakhala ngati ulemu waukulu kwa khama la gulu lathu losatopa. Pamene ankakonza zida, kuwala kwa dzuwa kwa dzuwa kunadutsa mumlengalenga wa workshop, ndikuwala bwino pamakina ozizira achitsulo. Ataima patsogolo pa chimango cha mapulaneti chomwe chidasinthidwa, malingaliro akuya a kuchita bwino adadza mkati mwake.

Zimene timapereka sizimangogwiritsa ntchito makina oziziritsa kapena ukadaulo wapamwamba - zimasonyeza kuteteza katundu wa makasitomala ndi kulemekeza luso ndi kudzipereka kosalekeza. Pamene laser yazima ndipo zida zapachikidwa, timatenga zida zathu, koma timasiya mbiri yodalirika komanso yodalirika yomwe imapangidwa ndi makasitomala athu. Izi zimapangitsa kuti tidzipereke tsiku lililonse ku malo aliwonse opangira zinthu omwe timapitako.
