kufotokozera1
Malo olumikizirana bwino a maloboti anzeru
Malumikizidwe a maloboti anzeru, monga malumikizidwe a thupi la munthu, ali ndi zofunikira kwambiri pa zipangizo zomwe zimakhala ndi kusinthasintha komanso mphamvu yonyamula. Njira yopangira zinthu pogwiritsa ntchito aloyi ya aluminiyamu imalola kuti chimbudzi cholumikizira chizitha kudzaza bwino madzi a aluminiyamu m'makona aliwonse ang'onoang'ono a nkhungu yovuta panthawi yopangira zinthu. Mwachitsanzo, chimbudzi cholumikizira dzanja cha loboti yamafakitale yokhala ndi ma axis asanu ndi limodzi chili ndi makulidwe a khoma a 3-5mm okha, koma chimatha kunyamula mphamvu ya 50-100N・m, chifukwa cha kapangidwe kolimba kamene kamaperekedwa ndi kupangira zinthu pogwiritsa ntchito mphamvu yothamanga kwambiri. Pakupanga, timawongolera kutentha kwa 660±5℃ kuti chimbudzi cholumikizira aluminiyamu chigwirizane bwino ndi nkhungu pansi pa mphamvu yothamanga ya 100-150MPa, kuonetsetsa kuti kulondola kwa chimbudzicho kufika pa ±0.1mm ndipo kuuma kwa pamwamba pa Ra kumayendetsedwa mkati mwa 1.6μm, ndikuyika maziko a kusonkhana kolondola kwambiri komanso kugwiritsa ntchito bwino zigawo zolumikizira.
Nyumba zochepetsera
Monga gawo lofunikira kwambiri lotumizira, khalidwe la nyumba ya loboti yochepetsera mphamvu limakhudza mwachindunji magwiridwe antchito ndi kukhazikika kwa ma transmission. Nyumba yochepetsera mphamvu yopangidwa ndi aluminiyamu yopangidwa ndi kupopera kwamphamvu kwambiri imakhala ndi kukhazikika kwa kutentha komanso mphamvu zamakanika. Tengani nyumba yochepetsera mphamvu ya harmonic mwachitsanzo. Ngakhale ndi yaying'ono, ili ndi kapangidwe kovuta kokhala ndi mano opyapyala komanso mabowo omangira mkati. Panthawi yoponyera, timagwiritsa ntchito ukadaulo wapamwamba wopanga nkhungu ndi kukonza bwino kuti tiwongolere kusintha kwa nyumba mkati mwa 0.05mm pansi pa mphamvu yosinthira ya 80-120MPa. Nthawi yomweyo, kudzera mu njira yapadera yochizira pamwamba, kukana kwa kuvala kwa nyumbayo kumawonjezeka, ndipo kulondola kwa ma transmission kumatsimikizika panthawi yoyendetsa loboti yobwerezabwereza pafupipafupi, mtengo wokonza umachepetsedwa, moyo wautumiki umakulitsidwa, ndipo chitsimikizo chodalirika chotumizira chimaperekedwa kuti loboti yanzeru iyende bwino.
Nyumba yowongolera
Malo owongolera a loboti yanzeru sayenera kungoteteza zida zamagetsi zamkati kuchokera ku malo akunja, komanso kukhala ndi magwiridwe antchito abwino otenthetsera kutentha. Malo owongolera opangidwa ndi aluminiyamu yokhala ndi mphamvu yayikulu yopopera ali ndi nthiti 10-15 zotenthetsera kutentha zomwe zimagawidwa mofanana pautali wa 150-200mm kudzera mu kapangidwe ka nthiti zotenthetsera kutentha, ndipo mtunda umayendetsedwa bwino pa 3-5mm. Loboti ikapanga kutentha panthawi yogwira ntchito mosalekeza, kutentha kwakukulu kwa aluminiyamu (kutenthetsera kutentha kwa 100-200W/(m・K)) kumatha kusamutsa kutentha mwachangu pamwamba pa chipolopolo, kenako kuwongolera kutentha mkati mwa malo ogwirira ntchito otetezeka a zida zamagetsi (nthawi zambiri osapitirira 60℃) kudzera pakukhudzana pakati pa nthiti zotenthetsera kutentha ndi mpweya. Nthawi yomweyo, magwiridwe ake abwino oteteza maginito amaletsa kusokoneza maginito ndikuwonetsetsa kuti wowongolerayo akugwira ntchito mokhazikika, zomwe ndi chitetezo cholimba cha "ubongo" wogwira ntchito bwino wa loboti yanzeru.

FAQ
Q1: Kodi mungatsimikizire bwanji kuti ziwalo za loboti zopangidwa ndi aluminiyamu yopangidwa ndi kupopera kwamphamvu kwa aluminiyamu zikukhala zolimba pogwiritsa ntchito pafupipafupi?
A1: Timalamulira mosamala magwero a zipangizo ndikusankha aluminiyamu apamwamba kwambiri kuti titsimikizire kuti mphamvu zawo zokoka zitha kufika 250-300MPa. Pa nthawi yogwiritsa ntchito mphamvu yopopera, kuwongolera molondola kwa magawo a njira kumapangitsa kuti kapangidwe ka mkati mwa chopoperacho kakhale kolimba ndipo kumachepetsa zolakwika monga ma pores ndi zolumikizira. Nthawi yomweyo, kudzera mu kulimbitsa kutentha komwe kumachitika pambuyo pake, kupsinjika kwamkati kumachotsedwa ndipo mphamvu yotopa ya zigawozo imawongoleredwa kwambiri. Pakugwiritsa ntchito kwenikweni, pambuyo pa kuyesa koyeserera, chipolopolo cha loboti chingathebe kukhalabe ndi magwiridwe antchito okhazikika pansi pa 10^7 cycles of loading, kukwaniritsa zosowa za kugwiritsa ntchito pafupipafupi.
Q2: Kodi kulondola kwa magawo a ma robot okhala ndi mawonekedwe ovuta kungatsimikizidwe?
A2: Zachidziwikire. Timagwiritsa ntchito ukadaulo wapamwamba wopanga nkhungu ndi zida zoponyera molondola. Pa gawo lopangira nkhungu, timagwiritsa ntchito kusanthula kwa kompyuta kuti tikonze bwino njira yothira ndi kugawa kwa kutentha kwa nkhungu. Panthawi yoponyera, madzi a aluminiyamu amadzazidwa molondola m'chibowo cha nkhungu mwachangu komanso mwamphamvu kudzera mu chipangizo chojambulira cholondola kwambiri, kotero kuti kulondola kwa gawo la kuponyera kumatha kufika pamlingo wa IT7-IT8, ndipo kusiyana kwa magawo ofunikira kumayendetsedwa mkati mwa ±0.05mm, zomwe zimakwaniritsa mokwanira zofunikira zosonkhanitsira zolondola kwambiri za maloboti anzeru opangira zinthu zooneka ngati zovuta.
Q3: Kodi ziwalo za loboti zopangidwa ndi aluminiyamu yopangidwa ndi mphamvu yamagetsi yothamanga kwambiri zitha kuwononga?
A3: Tili ndi njira zabwino zotetezera izi. Choyamba, sankhani zinthu zopangidwa ndi aluminiyamu zokhala ndi zinyalala zochepa kuti muchepetse chiopsezo cha dzimbiri. Mukamaliza kuyika, njira zapadera zoyeretsera pamwamba monga anodizing zidzachitika kuti apange filimu yokhuthala ya oxide yokhala ndi makulidwe a 10-25μm. Filimuyi ili ndi kukana kwabwino kwa dzimbiri ndipo imatha kukana bwino zinthu zowononga monga ma acid, alkali ndi mchere m'malo opangira mafakitale. Pambuyo pa mayeso a mchere, zotayidwazo sizinali ndi dzimbiri loonekera pamwamba pamalo opaka mchere kwa maola 500, zomwe zimatsimikizira kuti zigawo za loboti zikugwira ntchito bwino nthawi yayitali m'malo ovuta.
Q4: Kodi nthawi yoperekera zinthu ndi yayitali kwambiri pakupanga zinthu za loboti zopangidwa ndi aluminiyamu yokhala ndi mphamvu zambiri?
A4: Tili ndi njira yopangira yokonzedwa bwino komanso njira yabwino yoperekera zinthu. Kuyambira zofunikira kwa makasitomala mpaka kapangidwe ka nkhungu ndi kupanga, mpaka kupanga zinthu zoyeserera komanso kupanga zinthu zambiri, ulalo uliwonse umalumikizidwa kwambiri. Pazinthu zomwe zimapangidwa mwamakonda za kukula ndi kapangidwe kake, kutumiza kumatha kumalizidwa mkati mwa masabata 3-4; pazigawo zovuta komanso zazikulu, nthawi yotumizira ndi masabata 6-8 okha. Nthawi yomweyo, tidzasunga kulumikizana ndi makasitomala nthawi yeniyeni, kupereka ndemanga pa nthawi yake pakupita patsogolo kwa kupanga, ndikuwonetsetsa kuti mapulojekiti a makasitomala akupita patsogolo bwino.
Q5: Kodi mtengo wa zida za loboti zoponyera zinthu za aluminiyamu ndi wokwera kwambiri?
A5: Poganizira za ubwino wa nthawi yayitali, phindu la mtengo wake ndi lodziwikiratu. Ngakhale kuti mtengo wa zinthu zopangira aluminiyamu ndi wokwera pang'ono kuposa wa mapulasitiki ena auinjiniya, njira yopangira zinthu pogwiritsa ntchito mphamvu zambiri imatha kupanga zinthu zozungulira, zomwe zimapangitsa kuti zinthu zigwiritsidwe ntchito mpaka 85% - 95%, zomwe zimachepetsa ndalama zogwirira ntchito. Nthawi yomweyo, panthawi yopanga zinthu zambiri, mtengo wogawana nkhungu umachepetsedwa, ndipo magwiridwe antchito opangira zinthu amakhala okhazikika, zomwe zimachepetsa ndalama zokonzanso zinthu ndi zotsalira zomwe zimayambitsidwa ndi mavuto aubwino. Poyerekeza ndi njira zachikhalidwe zopangira zinthu, mtengo wonse ukhoza kuchepetsedwa ndi 20% - 30%, zomwe zimapatsa makampani anzeru a roboti mayankho ogwiritsira ntchito zinthu zotsika mtengo.
