3D design course mu 360. Njira zosavuta nthawi yomweyo! - Phunziro 5
Ili ndilo gawo lachisanu la maphunziro a Autodesk Fusion 360. M'miyezi yapitayi, tinakambirana mbali zazikulu za pulogalamuyi: kupanga zolimba zosavuta, cylindrical ndi zozungulira. Tapanga chotengera cha mpira - chopangidwa ndi pulasitiki. Kenaka tinapanga luso lopanga maonekedwe ovuta kwambiri. Nthawi ino tithana ndi ma angle giya ndi magiya.
Zinthu zina zamakina zimakonda kusweka nthawi zambiri, izi zimagwiranso ntchito ku nyenyezi. kumabweretsa njira yothetsera mavuto ena - mwachitsanzo, ndi gearbox yosowa.
Njira
Timayamba ndi chinthu chosavuta. Magiya nthawi zambiri amakhala masilindala okhala ndi mano odulidwa kapena owotcherera. Timayamba kujambula pa ndege ya XY ndikujambula mozungulira ndi utali wa 30 mm. Timatambasula mpaka kutalika kwa 5 mm - umu ndi momwe silinda imapezera, momwe timadula mano (chifukwa chomwe timatha kulamulira bwino kukula kwa zida zomwe zimapangidwira).
1. Maziko opangira choyikapo
Chotsatira ndikujambula template yomwe idagwiritsidwa ntchito popanga mano. Pa imodzi mwa maziko a silinda, jambulani trapezoid yokhala ndi maziko a 1 ndi 2 mm kutalika. Pulogalamuyi imakupatsani mwayi kuti musajambule gawo lalitali la trapezoid - titha kudziwa kutalika kwake chifukwa cha mfundo zomwe zili kumapeto kwa "mapewa" ake. Timazungulira ngodya zazifupi pogwiritsa ntchito zosankha pa tabu ya sketch ntchito. Timadula chojambula chopangidwa mozungulira silinda yonse ndikuzungulira mbali zakuthwa. Malo a clove imodzi ndi okonzeka - kubwereza 29 zina. Njira yomwe yatchulidwa m'mabuku akale a maphunzirowa idzathandiza, i.e. kubwerezabwereza. Njirayi imabisika pansi pa dzina la Chitsanzo pa tabu yomwe timasankha mtunduwo.
2. Bowo ladulidwa mu mphako imodzi
Posankha chida ichi, timasankha malo onse odulidwa omwe adapangidwa (kuphatikiza ozungulira). Pitani ku gawo la Axis pawindo lothandizira ndikusankha olamulira omwe odulidwawo adzabwerezedwa. Tikhozanso kusankha m'mphepete mwa silinda - zotsatira zake zidzakhala zofanana. Timabwereza kubwereza 30 (timalowa muwindo lomwe likuwonekera pamunda wogwira ntchito pafupi ndi chitsanzo kapena pawindo lothandizira). Popanga zida, muyenera kuyeserera pang'ono kuti mupeze kukula kwa dzino.
Njira okonzeka. Kuonjezera dzenje kuti mukweze gudumu pa axle sikuyenera kukhala vuto panthawiyi pamaphunzirowa. Komabe, popanga bwalo loterolo, funso likhoza kubwera: "Bwanji osakoka mano pachithunzi choyamba m'malo mowadula mu silinda?".
3. Kubwereza pang'ono ndipo choyikapo ndi chokonzeka
Yankho ndi losavuta - ndi losavuta. Ngati pakufunika kusintha kukula kapena mawonekedwe, ndikwanira kusintha zojambula za dzino. Ngati izi zikanachitidwa muzolemba zoyamba, kukonzanso kwathunthu kwa chojambulacho kukanafunika. Amapangidwa kuti agwiritse ntchito kubwerezabwereza, kuchitapo kanthu pachitsanzo, kubwereza zomwe zachitika kapena nkhope zosankhidwa za chinthucho (1-3).
Zida zamakona
Timafika ku gawo lovuta pang'ono la phunzirolo, ndiko kuti, kufalikira kwa ngodya. Amagwiritsidwa ntchito kusintha kolowera, nthawi zambiri 90 °.
Chiyambi chidzakhala chofanana ndi mu gear. Jambulani bwalo (m'mimba mwake 40 mm) pa ndege ya XY ndikuyijambula (ndi 10 mm), koma ikani chizindikirocho kukhala 45 °. Timapanga chojambula cha template yodula mano, monga bwalo lokhazikika. Timajambula zitsanzo zoterezi pa ndege zapansi ndi zapamwamba. Chojambula chapansi pa nkhope chiyenera kukhala chowirikiza kawiri kuposa chojambula chapamwamba. Mtengo uwu umachokera ku chiŵerengero cha madiameter apamwamba ndi apansi.
4. Maziko okonzekera zida za bevel
Popanga chojambula, tikulimbikitsidwa kuchikulitsa kuti chituluke pang'ono kuchokera pansi kuti chipewe ndege zokhala ndi zero makulidwe. Izi ndi zinthu zachitsanzo zomwe kupezeka kwake kuli kofunikira chifukwa cha kukula kolakwika kapena sketch yolakwika. Iwo akhoza kulepheretsa ntchito ina.
Titapanga zojambula ziwiri, timagwiritsa ntchito Loft, kuchokera pa bookmark. Sitepe iyi idakambidwa m'magawo am'mbuyomu pophatikiza zojambula ziwiri kapena zingapo kukhala zolimba. Iyi ndi njira yabwino kwambiri yosinthira zosalala pakati pa mawonekedwe awiri.
5. Dulani kuchokera pazithunzi ziwiri
Timasankha njira yomwe tatchulayi ndikusankha tizithunzi zonse ziwiri. Chidutswa chodulidwa chachitsanzocho chidzawonetsedwa mofiira, kotero tikhoza kuyang'anitsitsa nthawi zonse ngati mawonekedwe osafunika kapena ndege zimapangidwira. Pambuyo pa mgwirizano, notch imapangidwa pa clove imodzi. Tsopano imatsalira kuzungulira m'mphepete kuti mano agwere mosavuta mu cutout. Bwerezani odulidwawo mofanana ndi giya wamba - nthawi 25 (4-6).
6. Anamaliza Pakona Rack
Zida za nyongolotsi
Zida za nyongolotsi zikusowabe pagulu la zida. Imagwiranso ntchito pakufalitsa kozungulira. Amakhala ndi screw, i.e. nyongolotsi, komanso choyikapo ndi pinion. Poyang'ana koyamba, kukhazikitsa kwake kumawoneka kovuta kwambiri, koma chifukwa cha ntchito zomwe zilipo mu pulogalamuyi, zimakhala zosavuta monga momwe zinalili ndi zitsanzo zam'mbuyo.
7. Ndodo yomwe tidzadula magiya
Tiyeni tiyambe ndi kujambula bwalo (40mm m'mimba mwake) pa ndege ya XY. Kuchikoka mpaka kutalika kwa 50 mm, timapanga silinda yomwe nkhono idzadulidwa. Kenako timapeza ndikusankha ntchitoyo kuchokera pa tabu, ndiye pulogalamuyo imatiuza kuti tiyendetse chojambula ndikujambula mozungulira, chomwe chidzakhala china chake ngati pakatikati pa ozungulira omwe tangopanga kumene. Bwalo likakokedwa, kasupe amawonekera. Gwiritsani ntchito miviyo kuti muyike kuti ikhale pamwamba pa silinda. Muwindo lothandizira, sinthani parameter kukhala 6 ndi parameter. Ife ndithudi kudula ndi kuvomereza opareshoni. Nyongolotsi yangopangidwa kumene, i.e. chinthu choyamba chochepetsera (7, 8).
Kwa nyongolotsi yopangidwa kale, muyeneranso kuwonjezera choyikapo choyenera. Sizidzakhala zosiyana kwambiri ndi rack kumayambiriro kwa phunziro ili - kusiyana kokha ndi kukula ndi mawonekedwe a ma prong, omwe amachokera ku mawonekedwe a notch pa cochlea. Zitsanzo zonse zikayikidwa kuti zikhale pafupi ndi mnzake (kapena zophatikizika pang'ono), titha kujambula mawonekedwewo. Bwerezani odulidwawo monga momwe zinalili kale ndikudula dzenje la ekseli. Ndikoyeneranso kudula dzenje mu nkhono kuti amangirire olamulira.
9. Zinthu zowoneka ndi matupi awiri odziyimira pawokha.
Panthawiyi, magiya ali okonzeka, ngakhale akadali "atapachikika mumlengalenga" (9, 10).
10. Zida za nyongolotsi zakonzeka
Nthawi Yowonetsera
Magiya opangidwa adzayikidwa munjira zosiyanasiyana, chifukwa chake ndi oyenera kuyesedwa. Kuti tichite izi, tidzakonzekera makoma a bokosi momwe tidzayikamo magiya. Tiyeni tiyambe kuyambira pachiyambi, ndipo kuti tisunge zinthu ndi nthawi, tidzapanga choyikapo wamba magiya awiri oyamba.
Yambitsani chojambula pa ndege ya XY ndikujambula rectangle ya 60x80mm. Timadula 2 mm. Timawonjezera chinthu chomwecho ku ndege ya XZ, motero timapanga gawo la angular lomwe tidzakwera magiya opangidwa. Tsopano zimatsalira kudula mabowo a ma axles omwe ali pa imodzi mwa makoma amkati mwa ngodya. Mabowowo akhale otalikirapo kuposa 20mm kuchokera kuzinthu zina kuti choyimira cha 40mm chikhale ndi malo opindika. Tikhozanso kuwonjezera nkhwangwa kuti magiya ayatse. Ndimasiya chitsanzo ichi popanda kufotokozera mwatsatanetsatane, chifukwa panthawiyi maphunzirowo adzakhala ngati kubwerezabwereza kosafunikira (11).
11. Chitsanzo choyikapo mashelufu
Zida za nyongolotsi tidzayiyika mumtundu wa dengu momwe idzagwirira ntchito. Nthawi ino sikwele sikuyenda bwino. Chifukwa chake, tiyamba kupanga silinda momwe zomangira zimazungulira. Kenaka timawonjezera mbale yomwe tidzayikapo choyikapo.
Timayamba zojambulajambula pa ndege ya YZ ndikujambula mozungulira ndi m'mimba mwake 50 mm, zomwe timatuluka mpaka kutalika kwa 60 mm. Pogwiritsa ntchito Shell, timabowola silinda, ndikusiya makulidwe a khoma la 2 mm. Mzere womwe tidzakwezera auger uyenera kukhala ndi mfundo ziwiri zothandizira, kotero tsopano tidzabwezeretsa khoma lomwe linachotsedwa panthawi ya "Shell". Izi zimafuna kuti mujambulenso - tiyeni titengerepo mwayi ndikuzipanga kukhala zolimba. Chinthu ichi chiyenera kuchotsedwa pang'ono kuchokera ku chachikulu - zomwe zaganiziridwa kale zidzakuthandizani ndi izi.
Timajambula bwalo ndi m'mimba mwake molingana ndi kukula kwa silinda, ndikujambula 2 mm. Kenaka yonjezerani flange pamtunda wa 2,1 mm kuchokera pakhoma lopangidwa (timachita izi mu gawo la sketch la flange). Timatambasula kolala ndi 2 mm - nkhono sidzalola zambiri. Mwanjira iyi, timapeza zomangira zokhazikika ndi zomangira zake zosavuta.
Inde, musaiwale kudula mabowo a chitsulo. Ndikoyenera kuyang'ana mkati mwa chowongolera pang'ono - titha kuchita izi ndikudula molunjika. Pa ndege ya XZ, timayamba kujambula ndikujambula nkhope yomwe tidzayikapo choyikapo. Khoma liyenera kukhala 2,5mm kuchokera pakati pa silinda ndipo danga la axial likhale 15mm kuchokera pamwamba pa silinda. Ndikoyenera kuwonjezera miyendo ingapo yomwe mungathe kuikapo chitsanzo (12).
Chidule
Kupanga magiya sikulinso vuto kwa ife, ndipo titha kuziwonetsa mokongola. Zitsanzozi zidzagwira ntchito muzojambula zapakhomo ndipo, ngati n'koyenera, zidzalowa m'malo owonongeka a zipangizo zapakhomo. Magiyawa ali ndi mano akulu kuposa akufakitale. Izi ndichifukwa cha zofooka zaukadaulo - mano ayenera kukhala okulirapo kuti apeze mphamvu yofunikira.
13. Zida zosindikizidwa za nyongolotsi
Tsopano tikungoyenera kusewera ndi zomwe taphunzira kumene ndikuyesa makonda osiyanasiyana (13-15).
