Kwimveliso yeIibhore ze-cylinder zemoto, inkqubo yokuhoya ibalulekile ekuphumezeni okufunekayoukuchaneka, ukugqiba komphezulu, kwayeukuchaneka kwejometri. Umatshini wokuhombisa udlala indima ephambili ekusulungekiseni umphezulu we-cylinder bore ukuhlangabezana neemfuno ezingqongqo zokusebenza kwe-injini, ukusebenza kakuhle, kunye nokuphila ixesha elide.
Kutheni aUmatshini wokuhombisaiyafuneka:
Iibhore ze-cylinder zizinto ezibalulekileyo kwi-injini, njengoko zigcina ipiston kwaye kufuneka zinike indawo echanekileyo, egudileyo ukuze iipiston zityibilike. Ngexesha lenkqubo yokuvelisa, iibhore ze-cylinder ngokuqhelekileyo zidalwe ngeenkqubo ezifanaiyadikaokanyeukugrumba. Ngelixa ezi nkqubo zivelisa ubume be-cylinder esisiseko, aziboneleli ngesiphelo somphezulu sokugqibela esifunekayo kwintshukumo efanelekileyo yepiston, ukugcinwa kweoyile, kunye nokumelana nokunxiba. Kulapho umatshini wokuhoya ungena khona.
Iumatshini wokuhoyaibalulekile ku:
Ukufezekisa Ukuchaneka: Iibhore ze-cylinder kufuneka zibe nobubanzi obuchanekileyo, ubungqukuva, kunye nokuthe tye, ingakumbi kwiinjini zokusebenza eziphezulu-. Oomatshini beHoning babonelela ngohlengahlengiso olufanelekileyo oluyimfuneko ukuze kuqinisekiswe ukuba i-cylinder bore idibana nokunyamezelana okuqinileyo.
Ukudala uMphezulu oLungileyo Gqiba: Umgangatho wangaphakathi we-cylinder bore kufuneka ube nesicatshulwa esithile esikhuthaza ukutywinwa ngokufanelekileyo phakathi kwamakhonkco episton kunye nodonga lwe-cylinder. Kukwafuneka ivumele ukugcinwa kwe-oyile ngeyona ndlela ilungileyo ukunciphisa ukukhuhlana kunye nokuguga.
Ukuphucula imfezeko yeJiyometri: Inkqubo yokulola inceda ukuphelisa nakuphi na ukungafezeki okunje ngaphandle{{0}ku{1}}okungqukuva, ukucotha, okanye ukugqwetheka okubangelwa yinkqubo yangaphambili, ukuqinisekisa inyani, ibhore efanayo.
Imisebenzi yoMshini wokuHonga:
UkuQeda komphezulu: Ukunika imbeko kususa isixa esincinci semathiriyeli ekubholeni ukuze kuphuculwe ukugqitywa komphezulu, nto leyo efuna ukufikelela uburhabaxa bomphezulu kuluhlu lweRa 0,2 ukuba 1.0 microns(kuxhomekeke kwiinkcukacha zenjini). Ukuguda kuphucula ukusebenza ngokutywinwa kwamakhonkco episton.
Ubungakanani kunye noLawulo loNyamezelo: Umatshini wokuhombisa usetyenziselwa ukufezekisa ukugqibela, ububanzi obuchanekileyo be-cylinder bore, ukuqinisekisa ukuba ihambelana nepiston kwaye inika ukunyanzeliswa okufanelekileyo.
Ukujikeleza kunye nokuTsha: Inkqubo ye-honing iqinisekisa ukuba i-cylinder bore ijikeleze i-geometrically kwaye iqonde, isusa nakuphi na ukungahambelani kwiinkqubo zangaphambili zomatshini.
Ipateni yeCrosshatch: Ukuhoya kudala into ethileipateni yokuwelakumphezulu wombhobho, obalulekileyo ekugcineni ioli. Lo mzekelo unceda ekudaleni itywina elifanelekileyo kunye namakhonkco episton kunye nokunciphisa ukunxiba kwiindonga zombini kunye namakhonkco episton.
Deburring: Inkqubo ye-honing inceda ukususa nayiphi na i-burrs okanye imiphetho ebukhali eshiywe kumanyathelo omatshini angaphambili, ukuphucula umgangatho opheleleyo we-cylinder bore.
Iqhutywa njani iNkqubo yokuHlola:
Ukulungiselela:
I-cylinder bore iqala ngomatshini ukuya kubukhulu oburhabaxa kusetyenziswa iinkqubo ezifana nokudika okanye ukugrumba.
I-workpiece (ibhloko yesilinda) ifakwe ngokukhuselekileyo kumatshini we-honing.
Umatshini wokuhoya uyeamatye abrasiveokanyeamabhanti abrasiveezikhethwe ngokuthe ngqo ngokusekelwe ekugqityweni okufunwayo kunye nezinto eziphathekayo ze-cylinder.
Ukuseta isixhobo seHoning:
Amatye Abrasive: La matye axhonyweukulola iintlokoezijikeleza ngaphakathi kwibhore yesilinda. Amatye enziwa ngawoi-aluminium oxideokanyecubic boron nitride (CBN), kuxhomekeke kubunzima bezinto eziphathekayo.
I-Stroke Mechanism: Isixhobo sokulola sishukunyiswa ngokwentshukumo ({0}}kunye{1}}kunye{1}}phambili) ngaphakathi kwebhore. Esi senzo, kunye nokujikeleza kwamatye abrasive, kuqinisekisa ukuba ubuso busebenza ngokulinganayo.
Ukuthambisa: Ulwelo olukhethekileyo lokusika okanye i-coolant lusetyenziselwa ukuthambisa inkqubo ye-honing, ukunciphisa ukufudumala kobushushu kunye nokuthintela ukunxiba kwe-abrasive. Ikwanceda nokuthwala imathiriyeli entle esusiweyo kumbhobho.
Inkqubo Honing:
Ukwandiswa kweRadial kwaMatye aAbrasive: Njengoko isixhobo honing sihamba, iamatye abrasiveokanyeiibrashi ezirhabaxacinezela ujonge ngaphandle eludongeni lwesilinda, ngokuqhubekayo ucola kwaye upholise umphezulu webhore. Uxinzelelo olwenziweyo luhlala luphantsi ukuqinisekisa ukususwa kwezinto ezintle ngaphandle kokonakalisa umphezulu.
Iiparamitha ezilungisekayo: Umsebenzisi uhlengahlengisa iiparamitha eziphambili njengeisantya sokujikeleza, izinga lokubetha, kwayeUkwandiswa kobubanzi bamatyeukufezekisa ukugqiba okufunekayo, ijometri, kunye nobukhulu.
Ipateni yeCrosshatch: Ngexesha lenkqubo yokucoca, ukushukuma kwamatye abrasive kunye nokujikeleza kwesilinda kudalaipateni yokuwelaphezu komhlaba. Le pateni ibalulekile ekuphuculeni ukugcinwa kweoli kunye nokuqinisekisa ukutywinwa okufanelekileyo phakathi kwamakhonkco episton kunye nodonga lwesilinda.
Imilinganiselo yokugqibela:
Icylinder bore idayamithakulinganiswa kuyo yonke inkqubo ukuqinisekisa ukuba ubungakanani bombhobho bokugqibela buhambelana neenkcukacha ezifunekayo. Iubungqukuvakwayeukuthi tyeyebhore nazo ziqinisekisiwe.
Ukugqitywa komphezulu kuyajongwa, ngokuqhelekileyo ngeprofilometers yomphezulu, ukuqinisekisa ukuba iwela ngaphakathi koburhabaxa obufunekayo kunye nepateni yokuwela.
Ukugqiba:
Nje ukuba umphezulu ofunwayo ugqitywe kunye nokunyamezelwa kwe-dimensional kufezekisiwe, inkqubo ye-honing iyamiswa.
Ibhloko yesilinda iyasuswa kumatshini wokucoca kwaye icocwe ukuze isuse nayiphi na inkunkuma kunye nentsalela yokupholisa.
Isishwankathelo seNkqubo yokuHlola:
Rugh Machining: Iibhore ze-cylinder zidalwa ekuqaleni ngokukruqula okanye ukubhoboza.
Misela: I-workpiece ifakwe kumatshini we-honing, kwaye amatye abrasive okanye iibrashi zisekwe.
Ukuhlonipha: Isixhobo sihamba nge-radially kwaye sibuyisela ngaphakathi kwi-bore, sisusa izinto ezincinci zokuphucula ukujikeleza, ubungakanani kunye nokugqiba umphezulu.
Ukudalwa kwePatheni: Ipateni ye-crosshatch yenziwe phezulu, eyimfuneko ekugcineni i-oyile kunye nepiston efanelekileyo-yokutywinwa kweringi.
Imilinganiselo yokuGqibela kunye nokuCoca: Ibhore iyalinganiswa ukuze kuqinisekiswe ukuba zonke iinkcukacha zifezekisiwe, kwaye inxalenye iyacocwa ukuze idityaniswe ngakumbi.
Kutheni ukuhlonipha kubalulekile:
Ukuchaneka: Inkqubo ye-honing ifezekisa ukuchaneka okufunekayo kwi-tight fit phakathi kwepiston kunye ne-cylinder bore.
Umgangatho womphezulu: Ipateni egudileyo, ye-crosshatch eveliswa ngokuhombisa iqinisekisa ukuba amakhonkco episton angatywinwa ngokufanelekileyo kwaye udonga lwesilinda luthanjiswe ngokufanelekileyo.
Ukuqina: I-Honing iphakamisa ukuqina kwe-cylinder ngokuphucula umphezulu wayo ogqityiweyo kunye nejometri, ukunciphisa ukunxiba kuzo zombini i-cylinder kunye ne-piston rings ekuhambeni kwexesha.
Ukusebenza kakuhle kweNjini: Ukuhoya ngendlela eyiyo kukhokelela ekusebenzeni kakuhle kwe-injini, amandla, kunye nokunciphisa ukusetyenziswa kwe-oyile, nokuqinisekisa ukusebenza kwe-injini ixesha elide.
