Iyintoni inkqubo yokugqiba iibheringi?

Inkqubo yokugqiba i-superfinishing ayisetyenziswa kuphela kwishishini lokuthwala iibheringi, kodwa nakwiinjini, kwaye ezinye iimashini ezichanekileyo kunye nezixhobo nazo ziqalile ukusebenzisa le nkqubo.

Yintoni i-bearing superprecision?

Ukugqiba ukuthwala izinto ngendlela yokuthambisa, yindlela yokuthambisa esetyenziswa ngokutya ukuze kufezekiswe ukugaywa okuncinci.

Umphezulu ngaphambi kokuba ugqitywe ujikelezwe ngokuchanekileyo kwaye ucolwe. Ngokukodwa, ibhekisa kwindlela yokucubungula ethambileyo engenaxinzelelo lungako kwisixhobo sokusebenza esine-grained abrasive (ilitye leoyile) phantsi kweemeko ezilungileyo zokuthambisa kunye nokupholisa, kwaye yenza intshukumo ekhawulezayo nemfutshane yokujikeleza kwisixhobo sokusebenza ejikeleza ngesantya esithile kwicala lokujikeleza kwesixhobo sokusebenza esomileyo ngokuthe nkqo.

Iyintoni indima ye-superfinishing yebhereyitha?

Kwinkqubo yokuvelisa iibheringi eziqengqelekayo, ukugqiba okuphezulu yinkqubo yokugqibela yokucubungula iringi yokuthwala, edlala indima ebalulekileyo ekunciphiseni okanye ekupheliseni ukuphambuka okujikelezayo okushiywe kukucubungula, ukulungisa impazamo yesimo somsele, ukuphucula uburhabaxa bomphezulu wawo, ukuphucula iipropati zomzimba nezoomatshini zomphezulu, ukunciphisa ukungcangcazela kunye nengxolo yebheringi, kunye nokuphucula umsebenzi webheringi.

Ingabonakaliswa kwezi nkalo zintathu zilandelayo

1. Inganciphisa ngempumelelo ubungqindilili. Kwinkqubo yokugqiba kakhulu, ukuqinisekisa ukuba ilitye leoyile lihlala lisebenza kwincochoyi yamaza kwaye alidibani nomkhombe, i-arc yelitye leoyile edibana ne-workpiece ≥ ubude bobude bobungqindilili kumphezulu we-workpiece, ukuze uxinzelelo loqhagamshelwano lwe-crest lube lukhulu, kwaye incochoyi ejikelezayo isuswe, ngaloo ndlela kunciphisa ubungqindilili.

2. Ukuphucula impazamo yegroove yendlela yokugijima yebhola. Ukugqiba kakuhle kunokuphucula impazamo yegroove malunga ne-30% yeendlela zokugijima.

3. Ingabangela uxinzelelo oluxinzelelweyo kumphezulu wokugaya ocolekileyo kakhulu. Kwinkqubo yokugqiba, ukuguquka kweplastiki ebandayo kuveliswa kakhulu, ukuze emva kokugqiba, kubekho uxinzelelo oluxinzelelweyo oluseleyo kumphezulu womsebenzi.

4. Ingandisa indawo yoqhagamshelwano yomphezulu wokusebenza we-ferrule. Emva kokugqiba okuphezulu, indawo yoqhagamshelwano yomphezulu wokusebenza we-ferrule ingandiswa ukusuka kwi-15% ~ 40% emva kokusila ukuya kwi-80% ~ 95%.

Inkqubo yokugqiba ukuthwala:

1. Ukusika iibheringi

Xa umphezulu welitye lokusila udibana nencochoyi engqukuva yomphezulu wendlela erhabaxa, ngenxa yendawo encinci yoqhagamshelwano kunye namandla amakhulu kwindawo yeyunithi, phantsi kwesenzo soxinzelelo oluthile, ilitye lokusila liqala lisetyenziswe "ukusika ngasemva" kwesixhobo sokusila, ukuze inxalenye yamasuntswana arhabaxa kumphezulu welitye lokusila iwe kwaye iqhekeke, iveze iinkozo ezintsha ezibukhali kunye nemiphetho yokusila. Kwangaxeshanye, iqhuma lomphezulu wesixhobo sokusila liyasikwa ngokukhawuleza, kwaye umaleko wokonakala kwe-crest kunye nokugaya kumphezulu wesixhobo sokusila ziyasuswa ngokusika nangokusika ngasemva. Eli nqanaba libizwa ngokuba sisigaba sokusika, kwaye kule nqanaba apho uninzi lwesibonelelo sesinyithi lususwa khona.

2. Ukunqunyulwa kwesiqingatha seebheringi

Njengoko umatshini uqhubeka, umphezulu wesixhobo sokugalela uyagudiswa kancinci kancinci. Ngeli xesha, indawo yoqhagamshelwano phakathi kwelitye lokugalela nomphezulu wesixhobo sokugalela iyanda, uxinzelelo kwindawo nganye yeyunithi luyancipha, ubunzulu bokusika buyancipha, kwaye amandla okusika ayancipha. Kwangaxeshanye, iimbobo kumphezulu welitye lokugalela ziyavalwa, kwaye ilitye lokugalela likwimeko yokusika kancinci. Eli nqanaba laziwa njengesigaba sokugalela esisiqingatha sokugqiba isitya, apho amanqaku okusika kumphezulu wesixhobo sokugalela aba mhlophe kwaye abe nokukhanya okumnyama.

3. Inqanaba lokugqiba

Eli nqanaba linokwahlulwa libe ngamanyathelo amabini: elinye linqanaba lokutshintsha kokusila; elesibini linqanaba lokusila emva kokuyeka ukusika.

Isigaba sokutshintsha sokusila:

I-abrasive grain iyazilola ngokwayo, umphetho we-abrasive grain uyagudiswa, i-chip oxide iqala ukufakwa kwindawo engenanto yelitye leoyile, umgubo orhabaxa uvimba iimbobo zelitye leoyile, ukuze i-abrasive grain inqunyulwe kuphela kancinci, ihamba kunye nokukhupha kunye nokusila, emva koko uburhabaxa bomphezulu wento yokusebenza buncitshiswa ngokukhawuleza, kwaye umphezulu welitye leoyile unamatheliswe nge-black chip oxide.

Misa isigaba sokusika:

Ukungqubana kwelitye leoyile kunye neempahla zokusebenza kuye kwaba bushelelezi kakhulu, indawo yoqhagamshelwano inyuswe kakhulu, uxinzelelo luyehla, ingqolowa erhabaxa ikwazile ukungena kwifilimu yeoyile kwaye inxibelelane nempahla yokusebenza, xa uxinzelelo lwefilimu yeoyile yomphezulu wokuthwala lulinganiswe noxinzelelo lwelitye leoyile, ilitye leoyile liyadada. Ngexesha lokwenziwa kwefilimu yeoyile, akukho siphumo sokusika. Eli nqanaba likhethekile ekugqityweni okuphezulu.
