Inkqubo yokuguqula i-CNC
Ukujika kwe-CNC yinkqubo yomatshini apho isixhobo sokusika, ngokuqhelekileyo i-bit yesixhobo esingatshintshiyo, sichaza i-helix toolpath ngokuhambisa ngaphezulu okanye ngaphantsi ngomgca ngelixa i-workpiece ijikeleza.
Ngokuqhelekileyo igama elithi "ukujika" ligcinelwe ukuveliswa kwemigangatho yangaphandle ngesi senzo sokusika, ngelixa eli nyathelo libalulekileyo lokusika xa lisetyenziswa kwimigangatho yangaphakathi (imingxuma, yolunye uhlobo okanye enye) ibizwa ngokuba "yi-boring".Ngaloo ndlela ibinzana elithi "ukujika kunye nokukruqula" lihlela usapho olukhulu lweenkqubo ezaziwa njenge lathing.Ukusikwa kobuso kwindawo yokusebenza, nokuba ngesixhobo esijikayo okanye esikruqulayo, kuthiwa "ukujongana", kwaye kunokudityaniswa kulo naluphi na udidi njengeseti.
Ukuguqula kungenziwa ngesandla, ngendlela yendabuko ye-lathe, ehlala ifuna ukulawulwa okuqhubekayo ngumqhubi, okanye ngokusebenzisa i-lathe ezenzekelayo engenzi.Namhlanje olona hlobo luqhelekileyo lolo hlobo lokuzenzekelayo lulawulo lwamanani ekhompyutha, olwaziwa ngokuba yi-CNC.(I-CNC iqhele ukusetyenziswa kunye nezinye iintlobo ezininzi zoomatshini ngaphandle kokujika.)
Xa ujika, icwecwe (isuntswana lezinto ezomeleleyo njengeplanga, intsimbi, iplastiki, okanye ilitye) liyajikeleziswa size isixhobo sokusika sityhutywe ngamazembe asisi-1, esi-2, okanye esi-3 ukuze sivelise ubunzulu obuchanekileyo.Ukujika kunokuba ngaphandle kwe-cylinder okanye ngaphakathi (ekwabizwa ngokuba kukudika) ukuvelisa amacandelo e-tubular kwiijometri ezahlukeneyo.Nangona ngoku kunqabile, iileyile zakwangoko zingade zisetyenziswe ukuvelisa amanani ejometri antsonkothileyo, nkqu izinto eziqinileyo zeplatonic;nangona oko kwavela i-CNC iye yaba yinto engaqhelekanga ukusebenzisa ulawulo lwendlela yesixhobo engeyiyo eyekhompyutha ukulungiselela le njongo.
Iinkqubo zokuguqula ngokuqhelekileyo ziqhutyelwa kwi-lathe, ithathwa njengeyona nto indala yezixhobo zoomatshini, kwaye inokuba yeentlobo ezahlukeneyo ezifana nokujika okuthe ngqo, ukujika kwe-taper, iprofayili okanye i-grooving yangaphandle.Ezo ntlobo zeenkqubo zokujika zinokuvelisa iimilo ezahlukahlukeneyo zemathiriyeli ezinje ngokuthe tye, i-conical, i-curved, okanye i-grooved workpieces.Ngokubanzi, ukujika kusebenzisa izixhobo ezilula zokusika enye.Iqela ngalinye lezixhobo zokusebenza lineseti efanelekileyo yee-engile zesixhobo eziphuhliswe ukutyhubela iminyaka.
Amasuntswana enkunkuma yesinyithi evela kwimisebenzi yokujika aziwa ngokuba ziitshiphusi (kuMntla Melika), okanye i-swarf (eBritani).Kwezinye iindawo zisenokubizwa ngokuba zijiko.
Iiasi zokuhamba zesixhobo zinokuba ngumgca othe ngqo, okanye zisenokuba ecaleni kweseti yeegophe okanye ii-engile, kodwa zinomgca ocacileyo (kwingqiqo engeyiyo yezibalo).
Icandelo elixhomekeke kwimisebenzi yokuguqula linokubizwa ngokuba yi "Turned Part" okanye "iCandelo eliMachine".Imisebenzi yokuguqula iqhutyelwa kumatshini we-lathe onokuthi usebenze ngesandla okanye i-CNC.
Ukujika
Inkqubo eqhelekileyo yokuguqula iquka ukujikeleza inxalenye ngelixa isixhobo sokusika isicatshulwa esisodwa sishukunyiswa ngokuhambelana ne-axis yokujikeleza.Ukujika kungenziwa kumphezulu wangaphandle wenxalenye kunye nomgangatho wangaphakathi (inkqubo eyaziwa ngokuba yi-boring).Isixhobo sokuqala ngokuqhelekileyo sisicwecwe esiveliswa zezinye iinkqubo ezifana nokuphosa, ukubunjwa, ukukhupha, okanye ukuzoba.
Ukujika kwetapered
I-tapered turning ivelisa i-cylindrical shape eyancipha ngokukhawuleza ukusuka kwelinye icala ukuya kwelinye.Oku kunokufezekiswa a) ukusuka kwisilayidi sekhompawundi b) ukusuka kwi-taper turning attachment c) usebenzisa i-hydraulic copy attachment d) usebenzisa i-CNC lathe e) usebenzisa isixhobo sefom f) ngokususa i-tailstock - le ndlela ifaneleke ngakumbi kwi-shallow tapers.
Isizukulwana esingqukuva
Isizukulwana esingqukuva sivelisa umgangatho ogqityiweyo ongqukuva ngokujikela imo ejikeleze iaxis esisigxina ye revolution.Iimethodi ziquka a) ukusebenzisa i-hydraulic copy attachment b) i-CNC (elawulwa ngokwamanani ekhompyutheni) i-lathe c) usebenzisa isixhobo sefom (indlela erhabaxa nesele ilungile) d) usebenzisa i-bed jig (ifuna umzobo ukuchaza).
Ukujika nzima
Ukujika kanzima luhlobo lokuguqula olwenziwa kwizinto ezinobunzima be-Rockwell C obungaphezulu kwama-45. Kwenziwa ngokwesiqhelo emva kokuba i-workpiece iphathwe ubushushu.
Inkqubo yenzelwe ukubuyisela okanye ukunciphisa imisebenzi yesiko lokusila.Ukuguquguquka okunzima, xa kusetyenziselwa iinjongo zokususa isitokhwe kuphela, kukhuphisana ngokufanelekileyo nokusila ngokurhabaxa.Nangona kunjalo, xa isetyenziselwa ukugqiba apho ifom kunye nobukhulu bubaluleke kakhulu, ukugaya kuphezulu.Ukugaya kuvelisa ukuchaneka okuphezulu kwe-dimensional of roundness kunye ne-cylindricity.Ukongeza, umphezulu opolishiweyo ugqibezela i-Rz=0.3-0.8z awunakufezekiswa ngokujika nzima yedwa.Ukujika okunzima kufanelekile kwiindawo ezifuna ukuchaneka okujikelezayo kwe-0.5-12 micrometers, kunye / okanye uburhabaxa bomhlaba we-Rz 0.8-7.0 micrometres.Isetyenziselwa iigiya, iinxalenye zempompo yokutofa, kunye nezixhobo zehydraulic, phakathi kwezinye iinkqubo.
Ukujongana
Ukujongana nomxholo wokuguqula umsebenzi kubandakanya ukuhambisa isixhobo sokusika kwii-angles ezifanelekileyo kwi-axis yokujikeleza komsebenzi ojikelezayo.Oku kunokwenziwa ngokusebenza kwe-cross-slide, ukuba enye ifakwe, njengoko ihluke kwi-feed longitudinal (ukujika).Idla ngokuba luqhaqho lokuqala olwenziwayo kwimveliso yomsebenzi, kwaye kaninzi iba ngowokugqibela-kungoko ibinzana elithi "ukuphela".
Ukwahlukana
Le nkqubo, ikwabizwa ngokuba yi-parting off okanye cutoff, isetyenziselwa ukudala i-grooves enzulu eya kususa inxalenye egqityiweyo okanye inxalenye-epheleleyo kwisitokhwe sabazali bayo.
Grooving
I-Grooving ifana nokwahlula, ngaphandle kokuba i-grooves isikwa kubunzulu obuthile endaweni yokuqhawula icandelo eligqityiweyo / elipheleleyo kwi-stock.I-grooving inokwenziwa kwiindawo zangaphakathi nangaphandle, kunye nobuso benxalenye (i-grooving ebusweni okanye i-trepanning).
Imisebenzi engangqalanga ibandakanya:
Kuyadika
Ukwandisa okanye ukugudisa umngxuma osele ukho owenziwe ngokugrumba, ukubumba njl njl. njl. okt ukwenziwa kweefom zecylindrical zangaphakathi (ukuvelisa) a) ngokunyusa icwecwe lokuchwetheza kwindawo yokusonta ngechuck okanye kwiplate yobuso b) ngokunyusa iworkpiece kwisilayidi esinqamlezayo nokubeka isixhobo sokusika phakathi. ichuki.Lo msebenzi ulungele ukuphosa okunzima kakhulu ukukhwela kwipleyiti yobuso.Kwibhedi ende iileyile zokusebenzela ezinkulu zinokubotshelelwa kwisixhobo esisebhedini kunye neshafti egqithwe phakathi kweelugi ezimbini kwisixhobo sokusebenza kwaye ezi lugs zinokudikwa ngokobukhulu.Isicelo esilinganiselweyo kodwa esifumanekayo kwi-turner/machinist onobuchule.
Ukugrumba
Isetyenziselwa ukususa imathiriyeli ngaphakathi kwendawo yokusebenza.Le nkqubo isebenzisa amasuntswana okubhola asemgangathweni agcinwe emi kwisitokhwe somsila okanye isixhobo se-lathe.Inkqubo inokwenziwa ngoomatshini bokwemba abakhoyo ngokwahlukeneyo.
Knurling
Ukusikwa kwepateni ejikelezayo kumphezulu wenxalenye ukuze kusetyenziswe ukubamba isandla okanye njengophuculo olubonakalayo usebenzisa isixhobo esikhethekileyo sokugquma.
Ukuhlaziya kwakhona
Umsebenzi wokulinganisa osusa isixa esincinci setsimbi kumngxuma osele ugrunjiwe.Yenzelwe ukwenza imingxuma yangaphakathi yeediameter ezichanekileyo kakhulu.Umzekelo, umngxuma oyi-6mm wenziwa ngokugrumba nge-5.98 mm drill bit kwaye emva koko ubuyiselwe kwimilinganiselo echanekileyo.
Umsonto
Zomibini iintambo ze-screw ezisemgangathweni kunye nezingavumelekanga zingavulwa kwi-lathe usebenzisa isixhobo esifanelekileyo sokusika.(Idla ngokuba ne-60, okanye i-55° i-engile yempumlo) Nokuba ngaphandle, okanye ngaphakathi kwebhore(Ukusebenza ngokucofa yinkqubo yokwenza imisonto ngaphakathi okanye ngaphandle kumcu wokusetyenzwa. Ngokubanzi kubhekiselwa kuko njengokuthunga kwenqaku elinye.
Ukucofa amandongomane anemisonto kunye nemingxuma a) Ukusebenzisa iitephu zesandla kunye neziko letailstock b) usebenzisa isixhobo sokucofa esineclutch etyibilikayo ukunciphisa umngcipheko wokwaphuka kwetephu.
Imisebenzi yokuthunga ibandakanya a)zonke iintlobo zemisonto yangaphandle nengaphakathi kusetyenziswa isixhobo senqaku elinye kwakhona taper imisonto, imisonto yokuqalisa kabini, imisonto emininzi yokuqalisa, iintshulube njengoko zisetyenziswa kwiibhokisi zokunciphisa ivili leentshulube, i-leadcrew enemisonto enye okanye emininzi.b) ngokusetyenziswa kweebhokisi zokuthunga ezifakelwe izixhobo zefom ezi-4, ukuya kuthi ga kwi-2" yemitha yedayamitha kodwa kuyenzeka ukufumana iibhokisi ezinkulu kunale.
