I-CNC esezingeni eliphezulu

Enkambweni yokusika, udonga oluncane lukhubaza kalula amandla okusika, okuholela ekubukeni kwe-oval noma "i-waist shape" eneziphetho ezincane eziphakathi nendawo ezinkulu. Ngaphezu kwalokho, izindonga ezincane ibhasiAma-s athambekele ekuguqukeni kokushisa ngenxa yokungashisi kahle ukushisa ngesikhathi sokucubungula, futhi kunzima ukuqinisekisa ikhwalithi yokucubungula yezingxenye. Izingxenye eziboniswe emfanekisweni ongezansi azigcini nje ngokuphazamisa ukufaka nokubopha, kodwa futhi kunzima ukucubungula izingxenye ezicutshunguliwe. Kuyadingeka ukuklama i-casing ekhethekile enezindonga ezincane futhi umphini unogada.

▌ Ukuhlaziywa kwenqubo

Ngokwezidingo zobuchwepheshe ezinikezwe emdwebeni, i-workpiece icutshungulwa ngepayipi yensimbi engenamthungo. Ubukhulu obungaphezulu bembobo yangaphakathi kanye nodonga lwangaphandle yi-Ra1.6μm, engafinyelelwa ngokuphenduka, kodwa i-cylindricity yembobo yangaphakathi ingu-0.03mm, edingekayo ezingxenyeni ezinezindonga ezincane Eziphakeme. Ekukhiqizweni ngobuningi, umzila wenqubo ucishe uthi: ukwelashwa okungashisi-imoto ekupheleni ubuso-imoto eyindilinga yangaphandle-imoto yokuhlola imbobo yangaphakathi yekhwalithi.

Inqubo "ye-inner hole machining" iyisihluthulelo sokulawula ikhwalithi. Kunzima ngathi ukusika imbobo engaphakathi ngaphandle kwesiyingi esingaphandle kanye nekesi enezindonga ezincane ukuze siqinisekise isilinda esingu-0.03mm.

▌ Ubuchwepheshe obuyinhloko bembobo yemoto

Ubuchwepheshe obuyinhloko bomgodi wokuguqula ukuxazulula inkinga yokuqina nokususwa kwe-chip yethuluzi lokuguqula imbobo yangaphakathi. Ukwandisa ukuqina kwethuluzi elingaphakathi lokuguqula imbobo, thatha izinyathelo ezilandelayo:

(1) Zama ukukhulisa indawo ephambanayo yesibambi samathuluzi, imvamisa ithiphu yethuluzi elijikayo lembobo engaphakathi itholakala phezulu kwesibambi sethuluzi, ukuze indawo ephambanayo yesibambi sethuluzi ibe ncane, incane. kune-1/4 yendawo ephambanayo yembobo, njengoba kukhonjisiwe esithombeni esingakwesokunxele ngezansi. Uma ithiphu lethuluzi lokujika lembobo yangaphakathi litholakala kulayini ophakathi nendawo yesiphathi sethuluzi, indawo ephambanayo yesibambi samathuluzi emgodini ingandiswa kakhulu, ngale ndlela elandelayo.

(2) Ubude obunwetshiwe besibambi samathuluzi kufanele bube bubude obungu-5-8mm njengobude bomsebenzi ocutshungulwayo, ukuze kwandiswe ukuqina kwesibambi sethuluzi elijikayo futhi kuncishiswe ukudlidliza phakathi nenqubo yokusika.

▌ Xazulula inkinga yokukhishwa kwe-chip

Ikakhulukazi lawula isiqondiso sokuphuma kokuphumayo. Ithuluzi elijikajikayo lidinga ukuthi ama-chips agelezele phezulu ukuze enziwe ngomshini (ukukhishwa kwe-chip ngaphambili). Ngenxa yalesi sizathu, kusetshenziswa ithuluzi lokuguqula imbobo yangaphakathi elinomphetho omuhle, njengoba kuboniswe esithombeni esingezansi.

Lapho uqeda ukuphenduka, kuyadingeka ukuthi ama-chips ageleze aye enkabeni ukuze atshekisele i-chip phambili (ukususwa kwe-chip ephakathi nendawo), ngakho-ke lapho ulola ithuluzi, naka indlela yokugaya yonqenqema lokusika, kanye nendlela yokususa i-chip. ukutshekisela i-arc ngaphambili, njengoba kuboniswe emfanekisweni ongezansi ukuze ujike kahle Ingxubevange yommese isebenzisa i-YA6, uhlobo lwamanje lwe-M, olunamandla angcono okuguquguquka, ukumelana nokugqoka, ukuqina komthelela, nokumelana nensimbi nezinga lokushisa.

Lapho kucijiswa, i-engeli ye-rake iyindilinga ibe i-engeli emise okwe-arc engu-10-15°, futhi i-engeli yangemuva ikude ngo-0.5-0.8mm ukusuka odongeni ngokuya nge-machining arc (umugqa ophansi wethuluzi u-radian), futhi i-engeli enqenqemeni ka-c ingu-§0.5-1. I-wiper endaweni engu-B yonqenqema lwe-chip ngu-R1-1.5, i-engeli yokusiza iphansi ifinyelele ku-7-8 °, futhi iphuzu elingu-AA le-E edge yangaphakathi ligaywe libe yindingilizi ukuze kukhishwe ama-chips.

▌ Indlela yokucubungula

(1) I-shaft guard kufanele yenziwe ngaphambi kokucubungula. Inhloso eyinhloko yonogada be-shaft ukumboza imbobo yangaphakathi yomkhono omncane wemoto enodonga oluncane ngosayizi wangempela, futhi uyilungise ngezikhungo zangaphambili nangemuva ukucubungula umbuthano wangaphandle ngaphandle kokuguqulwa, nokugcina ikhwalithi kanye ukunemba kwendilinga yangaphandle. Ngakho-ke, ukucutshungulwa konogada be-shaft kuyisixhumanisi esibalulekile enqubweni yokucubungula i-casing enezindonga ezincane.

45﹟Insimbi eyindilinga yesakhiwo sekhabhoni isetshenziselwa ukucubungula indawo yokuvikela shaft ingenalutho; ubuso bokuphela kwemoto, izimbobo ezimbili ezimaphakathi ezimise okwe-B ziyavulwa, indilinga yangaphandle ilukhuni, kanti umkhawulo ungu-1mm. Ngemuva kokwelashwa kokushisa, ukushisa nokubumba, bese uphenduka kahle, ushiye umkhawulo ongu-0.2mm wokugaya. Shisisa kabusha ingaphezulu lomlilo ophukile libe ubulukhuni be-HRC50, bese uyigaya nge-cylindrical grinder njengoba kukhonjisiwe emfanekisweni ongezansi. Ukunemba kuhlangabezana nezidingo futhi kuzosetshenziswa ngemuva kokuqedwa.

(2) Ukuze uqedele ukucutshungulwa kwe-workpiece ngesikhathi esisodwa, okungenalutho kugcina indawo yokubopha kanye nomkhawulo wokusika.

(3) Okokuqala, phatha izikhala ngokushisisa, ukucisha kanye nokushisa, ubulukhuni buyi-HRC28-30 (ubulukhuni bebanga lokucubungula).

(4) Ithuluzi lokuguqula lamukela i-C620. Okokuqala, faka isikhungo sangaphambili ku-spindle cone bese usilungisa. Ukuze uvimbele ukubola kwe-workpiece lapho ubopha umkhono omncane onezindonga ezincane, kunezelwa umkhono owugqinsi we-loop, njengoba kuboniswe emfanekisweni ongezansi.

Ukuze kugcinwe ukukhiqizwa okukhulu, isiphetho sangaphandle se-casing enezindonga ezincane sicutshungulwa kusayizi ofanayo d, i-rula ye-t iyindawo yokubopha i-axial, futhi i-casing enezindonga ezincane iyacindezelwa ukuze kuthuthukiswe ikhwalithi yembobo yangaphakathi. yemoto nokugcina usayizi. Uma kucatshangelwa ukuthi ukusika ukushisa kukhiqizwa, usayizi wokunwebeka we-workpiece kunzima ukubamba. Kuyadingeka ukuthulula uketshezi olwanele lokusika ukuze unciphise ukuguquguquka okushisayo kwe-workpiece.

(5) Bopha ucezu lokusebenza ngokuqinile nge-othomathikhi ye-othomathikhi yemihlathi emithathu, phendulela ubuso obusekugcineni, bese ujikisa indilinga engaphakathi. Shiya imajini engu-0.1-0.2mm ukuze ujike kahle, futhi esikhundleni salo ufake ithuluzi elijikajikayo ukuze ucubungule umkhawulo wokusika kuze kube yilapho umshini wonogada uhlangabezana nezidingo zokulingana nobulukhuni ngokweqile. Khipha ithuluzi lokuguqula imbobo yangaphakathi, faka i-shaft yonogada phakathi nendawo engaphambili, sebenzisa isikhungo se-tailstock ukuze ubambe ngokuvumelana nezidingo zobude, shintsha ithuluzi lokujikisa langaphandle ukuze wenze roughen indilinga yangaphandle, bese uqedela ukuphendukela ezidingweni zokudweba. Ngemva kokudlulisa ukuhlolwa, sebenzisa ummese wokusika ukuze usike ubude ngokuvumelana nobukhulu obudingekayo. Ukuze wenze ukusika kube bushelelezi lapho i-workpiece inqanyuliwe, umkhawulo wokusika kufanele ucijiswe ukuze wenze ubuso bokugcina be-workpiece bushelelezi; ingxenye encane ye-shaft yokuqapha kufanele ibe phansi ukuze kuncishiswe igebe elishiywe ukusika, futhi umshini wokuqapha ukunciphisa ukuguqulwa komsebenzi, ukuvimbela ukudlidliza, futhi lapho usika Isizathu sokuwa nokulimaza.
