Isifundo se-3D design ngo-360. Izindlela ezilula ngokushesha! - Isifundo 5
Lolu wuhlelo lwesihlanu lwezifundo zokuklama ze-Autodesk Fusion 360. Ezinyangeni ezedlule, sixoxe ngezici eziyinhloko zohlelo: ukudala okuqinile okulula, okuyisilinda nokujikelezayo. Senze i-ball bearing - eyenziwe ngepulasitiki ngokuphelele. Sabe sesithuthukisa amakhono okudala izimo eziyinkimbinkimbi. Kulokhu sizobhekana namagiya e-angle namagiya.
Ezinye izakhi zemishini zithanda ukuphuka kaningi, lokhu kusebenza nasezintweni zezinkanyezi. kuletha isisombululo kwezinye izinkinga - isibonelo, nge-gearbox engekho.
Indlela
Siqala ngento elula. Amagiya ngokuvamile amasilinda anamazinyo asikiwe noma ashiselwe. Siqala umdwebo endizeni ye-XY bese udweba umbuthano nge-radius engu-30 mm. Siyinweba ifike ku-5 mm ukuphakama - yile ndlela i-cylinder etholakala ngayo, lapho sinquma khona amazinyo (ngenxa yokuthi sithola ukulawula okungcono phezu kobubanzi begiya elidala).
1. Isisekelo sokudala i-rack
Isinyathelo esilandelayo ukudweba isifanekiso esasetshenziswa ukwenza amazinyo. Kwesinye sezisekelo zesilinda, dweba i-trapezoid enesisekelo esingu-1 no-2 mm ubude. Uhlelo lukuvumela ukuthi ungadwebi isisekelo eside se-trapezoid - singakwazi ukunquma ubude bayo ngenxa yamaphuzu ekugcineni "kwamahlombe" ayo. Sizungeza amakhona ngendlela emfishane sisebenzisa izinketho kuthebhu yomsebenzi womdwebo. Sika umdwebo owenziwe sizungeze isilinda sonke bese sizungeza imiphetho ebukhali. Indawo ye-clove eyodwa isilungile - phinda izikhathi ezingama-29 ngaphezulu. Inketho eshiwo ezinhlelweni zangaphambilini zesifundo izoba usizo, i.e. ukuphindaphinda. Le nketho ifihliwe ngaphansi kwegama Iphethini kuthebhu lapho sikhetha khona inguqulo.
2. Umgodi usikwa ube inotshi eyodwa
Ngokukhetha leli thuluzi, sikhetha zonke izindawo zokusikwa okudaliwe (kuhlanganise neziyindilinga). Iya kupharamitha ye-Axis efasiteleni elisizayo bese ukhetha i-eksisi lapho ukusika kuzophindwa khona. Singakwazi futhi ukukhetha unqenqema lwesilinda - umphumela wokuphela uzofana. Siphinda ukuphindaphinda izikhathi ezingu-30 (singena efasiteleni elibonakalayo endaweni yokusebenza eduze kwemodeli noma efasiteleni elisizayo). Lapho udala amagiya, udinga ukuzilolonga kancane ukuze uthole usayizi wamazinyo ofanele.
Indlela ngomumo. Ukwengeza imbobo yokukhweza isondo ku-ekseli akumele kube yinkinga kuleli phuzu esifundweni. Kodwa-ke, lapho udala umbuthano onjalo, umbuzo ungase uphakame: "Kungani ungadwebi amazinyo emdwebeni wokuqala esikhundleni sokuwasika ube yi-cylinder?".
3. Ukuphindaphinda okumbalwa kanye ne-rack isilungile
Impendulo ilula kakhulu - ukuze kube lula. Uma kunesidingo sokushintsha usayizi noma ukuma, kwanele ukushintsha umdwebo wezinyo. Uma lokhu bekwenziwe ohlakeni lokuqala, bekuyodingeka ukubuyekezwa okuphelele komdwebo. Kuhlongozwa ukuthi kusetshenziswe umsebenzi wokuphindaphinda, osevele usebenza kumodeli, uphinda umsebenzi owenziwe noma ubuso obukhethiwe bento (1-3).
Igiya lekhona
Sifika engxenyeni enzima kakhudlwana yesifundo, okungukuthi, ukudluliselwa ekhoneni. Isetshenziselwa ukushintsha indlela, ngokuvamile engu-90°.
Isiqalo sizofana nesegiyeni. Dweba indilinga (ububanzi obungama-40 mm) endizeni ye-XY bese uyidweba phezulu (ngo-10 mm), kodwa ubeke ipharamitha ku-45°. Senza umdwebo wesifanekiso sokusika amazinyo, njengendilinga evamile. Sidweba amaphethini anjalo ezindizeni ezingezansi nezingaphezulu. Isifanekiso esisebusweni obuphansi kufanele sibe nobubanzi obuphindwe kabili kunomdwebo osebusweni obungaphezulu. Leli nani litholakala esilinganisweni sama-diameter angaphezulu naphansi.
4. Isisekelo sokulungiswa kwegiya le-bevel
Uma udala umdwebo, kunconywa ukuba uwukhulise ukuze uphume kancane esisekelweni ukuze ugweme izindiza ezinobukhulu be-zero. Lawa amamodeli ama-elementi akhona okudingekayo ngenxa yosayizi ongalungile noma umdwebo ongalungile. Bangaphazamisa umsebenzi owengeziwe.
Ngemva kokudala imidwebo emibili, sisebenzisa ukusebenza kwe-Loft, kusukela kubhukhimakhi. Lesi sinyathelo kuxoxiwe ngaso ezigabeni ezedlule zokuhlanganisa imidwebo emibili noma ngaphezulu ibe into eqinile. Lena indlela engcono kakhulu yokwenza izinguquko ezibushelelezi phakathi kwezimo ezimbili.
5. Sika emidwebo emibili
Sikhetha inketho eshiwo bese sikhetha zombili izithonjana. Isiqephu esisikiwe semodeli sizogqanyiswa ngokubomvu, ngakho-ke singakwazi ukuqapha njalo ukuthi ngabe imimo engadingeki noma izindiza ziyadalwa. Ngemuva kwesivumelwano, inotshi yenziwa ku-clove eyodwa. Manje kusele ukuzungeza imiphetho ukuze amazinyo awele kalula kusikwa. Phinda ukusika ngendlela efanayo negiya elivamile - kulokhu izikhathi ezingu-25 (4-6).
6. I-Finished Corner Rack
Igiya lezikelemu
Igiya lezikelemu alikatholakali egiyeni. Iphinde isebenze ekudluliselweni kwe-angular of rotation. Iqukethe isikulufu, i.e. isibungu, kanye ne-rack ne-pinion ejwayelekile. Ekuboneni kokuqala, ukuqaliswa kwayo kubonakala kuyinkimbinkimbi kakhulu, kodwa ngenxa yemisebenzi etholakala ohlelweni, kubonakala kulula njengoba kwenzeka kumamodeli wangaphambilini.
7. Induku esizosika ngayo amagiya
Ake siqale ngokudweba indilinga (ububanzi obungama-40mm) endizeni ye-XY. Ukuyidonsa ifike ku-50 mm ubude, sakha isilinda lapho umnenke uzosikwa khona. Bese sithola futhi sikhethe ukusebenza kuthebhu, bese uhlelo lusitshela ukuthi sigijime umdwebo bese sidweba umbuthano, ozoba yinto efana nomongo we-spiral esisanda kuyidala. Uma umbuthano usudwetshiwe, kuvela isiphethu. Sebenzisa imicibisholo ukuyibeka ukuze idlule isilinda. Ewindini elisizayo, shintsha ipharamitha ibe ngu-6 kanye nepharamitha. Sizosika futhi sigunyaze ukusebenza. Isibungu sisanda kwakhiwa, i.e. ingxenye yokuqala yesinciphisi (7, 8).
Ku-worm eyenziwe ngaphambili, udinga futhi ukwengeza i-rack efanelekile. Ngeke ihluke kakhulu ku-rack ekuqaleni kwalesi sifundo - umehluko kuphela ubukhulu nokuma kwama-prong, asekelwe ekubunjweni kwenotshi ku-cochlea. Uma womabili amamodeli ebekwe ukuze asondele komunye nomunye (noma adlulele kancane), singadweba umumo ohambisanayo. Phinda ukusika njengakwezimo ezedlule bese usika imbobo ye-axle. Kuyafaneleka futhi ukusika imbobo emnenkeni wokunamathisela i-axis.
9. Izakhi ezibonakalayo ziyimizimba emibili ezimele.
Kuleli qophelo, amagiya alungile, nakuba "aselenga emoyeni" (9, 10).
10. Igiya lezikelemu selilungile
Isikhathi Sesethulo
Amagiya adaliwe azofakwa ngezindlela ezahlukahlukene, ngakho-ke kufanelekile ukuhlolwa. Ukuze senze lokhu, sizolungisa izindonga zebhokisi lapho sizobeka khona amagiya. Ake siqale kusukela ekuqaleni, futhi ukonga impahla nesikhathi, sizokwenza ujantshi ovamile wamagiya amabili okuqala.
Qala umdwebo endizeni ye-XY bese udweba unxande ongu-60x80mm. Siyidonsela phezulu ngo-2 mm. Sengeza into efanayo endizeni ye-XZ, ngaleyo ndlela sidale isigaba se-angular lapho sizofaka khona amagiya adaliwe. Manje kusele ukusika izimbobo zama-axles atholakala kwelinye lamadonga angaphakathi ekhoneni. Izimbobo kufanele zibe kude ngaphezu kuka-20mm kwezinye izingxenye ukuze isitendi esingu-40mm sibe nendawo yokuzungeza. Singase sengeze izimbazo ukuze amagiya avuleke. Ngishiya le modeli ngaphandle kwencazelo enemininingwane, ngoba kulesi sigaba sesifundo kuzofana nokuphindaphinda okungadingekile (11).
11. Isibonelo se-shelving rack
Igiya lezikelemu sizoyifaka ohlotsheni lukabhasikidi lapho izosebenza khona. Kulokhu isikwele asisebenzi kahle kakhulu. Ngakho-ke, sizoqala ngokwenza isilinda lapho isikulufu sizozungeza. Bese sifaka ipuleti lapho sizofaka khona i-rack.
Siqala umdwebo endizeni ye-YZ bese udweba umbuthano onobubanzi obungama-50 mm, esiwukhipha ekuphakameni kuka-60 mm. Ngokusebenzisa ukusebenza kweShell, sikhipha isilinda, sishiya ukushuba kodonga okungama-2 mm. I-eksisi esizokhweza kuyo i-auger kufanele ibe namaphoyinti amabili okusekela, ngakho-ke manje sizobuyisela udonga olususiwe ngesikhathi sokusebenza kwe-"Shell". Lokhu kudinga ukuthi uyidwebe kabusha - asisebenzise lokho futhi sikwenze kube yizicucu. Lesi sici kufanele sisuswe kancane kwesikhulu - imisebenzi esivele icatshangelwe izosiza kulokhu.
Sidweba umbuthano ngobubanzi obuhambisana nobubanzi besilinda, bese siyidweba ngo-2 mm. Bese wengeza i-flange ebangeni elingu-2,1 mm ukusuka odongeni oludaliwe (senza lokhu esigabeni somdwebo we-flange). Selula ikhola ngo-2 mm - umnenke ngeke uvumele okwengeziwe. Ngale ndlela, sithola isikulufu esifakwe ngokuzinzile ngokuhlangana kwaso okulula.
Yiqiniso, ungakhohlwa ukusika izimbobo ze-axle. Kuyafaneleka ukuhlola ingaphakathi le-rig kancane - singakwenza lokho ngokusika okuqondile. Endizeni ye-XZ, siqala umdwebo bese sidweba ubuso lapho sizobeka khona i-rack. Udonga kufanele lube ngu-2,5mm ukusuka phakathi nendawo yesilinda futhi isikhala se-axial kufanele sibe ngu-15mm ukusuka ebusweni besilinda. Kuyafaneleka ukwengeza imilenze embalwa lapho ungabeka khona imodeli (12).
Isifinyezo
Ukukhiqizwa kwamagiya akuseyona inkinga kithina, sesikwazi nokuwethula kahle. Amamodeli azosebenza kuma-prototypes asekhaya futhi, uma kunesidingo, azothatha indawo yengxenye eyonakele yamadivayisi asekhaya. Amagiya anamazinyo amakhulu kunawawasefemini. Lokhu kungenxa yokulinganiselwa kobuchwepheshe - amazinyo kufanele abe makhudlwana ukuze athole amandla adingekayo.
13. Igiya lezikelemu eliphrintiwe
Manje kufanele sidlale ngemisebenzi esanda kufundwa futhi sihlole izilungiselelo ezihlukile (13-15).
