Iirobhothi zibonakala zikuyo yonke indawo kule mihla - kwiimuvi, kwizikhululo zeenqwelomoya, kwimveliso yokutya, nakwimizi-mveliso eyenza ezinye iirobhothi.Iirobhothi zinemisebenzi emininzi eyahlukeneyo kunye nokusetyenziswa kwazo, kwaye njengoko zisiba lula kwaye zingabizi kakhulu ukwenza, ziya zisiba yindawo eqhelekileyo kwishishini.Njengoko imfuno yerobhothi isanda, abavelisi berobhothi kufuneka baqhubeke, kwaye enye indlela esisiseko yokwenza iinxalenye zerobhothi bumatshini beCNC.Eli nqaku liza kufunda ngakumbi malunga nemigangatho yerobhothi kwaye kutheni i-CNC machining ibaluleke kakhulu ekwenzeni iirobhothi.
Umatshini we-CNC wenzelwe iirobhothi
Okokuqala, ukucwangciswa kwe-CNC kwenza ukuveliswa kwamalungu anexesha elikhawulezayo lokukhokela.Phantse nje ukuba imodeli yakho ye-3D ilungile, ungaqala ukwenza amacandelo ngomatshini we-CNC.Oku kuvumela ukuphindaphindwa okukhawulezayo kweeprototypes kunye nokuhanjiswa ngokukhawuleza kweendawo zerobhothi zesiko kwizicelo zobungcali.
Olunye uncedo lobuchwephesha be-CNC kukukwazi ukwenza ngokuchanekileyo iinxalenye ezithile.Oku kuchaneka kokwenziwa kwemveliso kubaluleke kakhulu kwiirobhothi, njengoko ukuchaneka komda kungundoqo ekwenzeni iirobhothi ezisebenza kakhulu.Ukuchaneka kweCNC machining kugcina ukunyamezela ngaphakathi +/- 0.0002 intshi, kwaye inxalenye ivumela ukunyakaza okuchanekileyo kunye nokuphindaphindiweyo kwerobhothi.
Ukugqitywa komphezulu sesinye isizathu sokusebenzisa i-CNC machining ukuvelisa iindawo zerobhothi.Amalungu asebenzisanayo kufuneka abe ne-friction ephantsi, kwaye ukuchaneka kwe-CNC machining kunokuvelisa iinxalenye ezinoburhabaxa bomhlaba obuphantsi njenge-Ra 0.8 μm, okanye iphantsi ngokusebenza emva kokulungiswa okufana nokupolisha.Ngokuchaseneyo, ukuphosa (phambi kokugqiba) kuvelisa uburhabaxa bomphezulu obukufutshane ne-5µm.Ushicilelo lweMetal 3D luvelisa umphezulu orhabaxa.
Okokugqibela, uhlobo lwezinto ezisetyenziswa yirobhothi ilungele ukwenziwa komatshini weCNC.Iirobhothi kufuneka zikwazi ukuhamba kwaye ziphakamise izinto ngokuzinzileyo, ezifuna izinto ezinamandla, ezinzima.Ezi mpawu ziyimfuneko zifezekiswa kakuhle ngokucofa iintsimbi ezithile kunye neeplastiki.Ukongeza, iirobhothi zihlala zisetyenziselwa ukwenza isiko okanye ukuvelisa umthamo ophantsi, okwenza ukuba i-CNC ithathe indawo yokhetho lwendalo kwiindawo zerobhothi.
Iindidi zamacandelo eRobhothi enziwe yi-CNC Machining
Ngemisebenzi emininzi enokwenzeka, iintlobo ezininzi ezahlukeneyo zeerobhothi ziye zavela.Kukho iintlobo ezininzi eziphambili zeerobhothi ezisetyenziswa ngokuqhelekileyo.Iirobhothi ezichazweyo zinengalo enye enamalungu amaninzi, abantu abaninzi abaye bayibona.Kukwakho ne-SCRA (i-Selective Compliance Articulated Robot Arm) irobhothi, enokuhambisa izinto phakathi kweenqwelomoya ezimbini ezinxuseneyo.I-SCRA inokuqina okuphezulu okuthe nkqo kuba intshukumo yabo ithe tye.Amalungu erobhothi yeDelta asezantsi, agcina ingalo ilula kwaye ikwazi ukuhamba ngokukhawuleza.Ekugqibeleni, iirobhothi ze-gantry okanye zeCartesian zinee-actuator ezihambelanayo ezihamba i-90 degrees enye kwenye.Nganye kwezi robhothi inolwakhiwo olwahlukileyo kunye nezicelo ezahlukeneyo, kodwa kukho izinto ezintlanu ngokubanzi ezenza irobhothi:
1. Ingalo yerobhothi
Iingalo zerobhothi zahluke kakhulu ngokwemo kunye nomsebenzi, ngoko ke kusetyenziswa iindawo ezininzi ezahlukeneyo.Nangona kunjalo, bonke banento enye abafana ngayo, kukukwazi kwabo ukushukuma okanye ukulawula izinto-njengengalo yomntu!Iindawo ezahlukeneyo zengalo yerobhothi zithiywe nangeezethu: igxalaba, ingqiniba kunye namalungu esihlahla ajikeleza kwaye alawule ukuhamba kwenxalenye nganye.
2. Ukuphelisa umphumo
Isiphelo sesiphumo sisincamatheliso esincanyathiselwe ekupheleni kwengalo yerobhothi.Iimpembelelo zokugqibela zikuvumela ukuba wenze ngokwezifiso ukusebenza kwerobhothi kwimisebenzi eyahlukeneyo ngaphandle kokwakha irobhothi entsha ngokupheleleyo.Ziyakwazi ukubamba, ii-grippers, i-vacuum cleaners okanye iikomityi zokufunxa.Ezi ziphumo zokugqibela ziqhelekile ziinxalenye zoomatshini be-CNC kwintsimbi (ngokuqhelekileyo i-aluminiyam).Enye yamacandelo ifakwe ngokusisigxina ekupheleni kwengalo yerobhothi.Eyona gripper, ikomityi yokufunxa, okanye amanye amaqabane aneendibano ukuze ilawuleke ngengalo yerobhothi.Olu cwangciso olunamacandelo amabini ahlukeneyo lwenza kube lula ukutshintshiselana ngeempembelelo zesiphelo ezahlukeneyo, ngoko ke irobhothi inokulungiswa kwizicelo ezahlukeneyo.Ungakubona oku kumfanekiso ongezantsi.Idiski esezantsi iya kubotshelelwa kwingalo yerobhothi, ikuvumela ukuba uqhagamshele umbhobho osebenza ikomityi yokufunxa kubonelelo lomoya werobhothi.
3. Imoto
Yonke irobhothi idinga iimotor ukuqhuba ukuhamba kweengalo kunye namalungu.Injini ngokwayo inamalungu amaninzi ashukumayo, uninzi lwawo olunokuba ngoomatshini beCNC.Ngokuqhelekileyo, i-motor isebenzisa uhlobo oluthile lwezindlu ezinomatshini njengomthombo wamandla, kunye nesibiyeli somatshini esidibanisa nengalo yerobhothi.Iibheringi kunye neeshafti nazo zihlala zisenziwa ngoomatshini be-CNC.Iishafti zingenziwa ngomatshini kwi-lathe ukunciphisa i-diameter okanye kwi-mill ukongeza iimpawu ezifana nezitshixo okanye iindawo zokubeka.Ekugqibeleni, ukunyakaza kwemoto kunokudluliselwa kumalungu okanye iigiya zezinye iindawo zerobhothi ngokugaya, i-EDM okanye i-gear hobbing.
4. Umlawuli
Umlawuli ngokusisiseko yingqondo yerobhothi kwaye ilawula iintshukumo ezichanekileyo zerobhothi.Njengekhompyuter yerobhothi, ithatha igalelo kuluvo kwaye ilungisa inkqubo elawula imveliso.Oku kufuna ibhodi yesekethe eprintiweyo (PCB) yokubeka izinto ze-elektroniki.Le PCB inokuba CNC ngoomatshini kubungakanani obufunwayo kunye nokumila phambi kokongeza amacandelo e-elektroniki.
5. Izivamvo
Njengoko sele kukhankanyiwe ngasentla, abenzi boluvo bafumana ulwazi malunga nendawo engqonge irobhothi kwaye balubuyisele kumlawuli werobhothi.Isivamvo sikwafuna iPCB, enokuthi yenziwe ngoomatshini beCNC.Ngamanye amaxesha ezi zinzwa zikwabekwe kwizindlu zoomatshini ze-CNC.
Iijigs kunye nezixhobo eziqhelekileyo
Ngelixa ingeyonxalenye yerobhothi ngokwayo, uninzi lwemisebenzi yerobhothi ifuna ukubamba isiko kunye nokulungiswa.Unokufuna i-gripper ukubamba inxalenye ngelixa i-robot isebenza kuyo.Ungasebenzisa kwakhona iigrippers ukubeka ngokuchanekileyo iindawo, ezihlala zifuneka ukuba iirobhothi zichole okanye zibeke iindawo.Ngenxa yokuba ziqhele ukuba yinxalenye yesiko elinye, umatshini we-CNC ufanelekile kwiijigi.
