Ububanzi bephinikhodi yokuphepha kufanele bunqunywe ngokuya ngesimo samandla sokugunda lapho kulayishwe kakhulu.Ngemikhiqizo yephinikhodi efana ne-DIN1 ne-DIN7, imfuneko enkulu ukunemba okuphezulu.Ukubekezelelwa kwephinikhodi evamile ye-cylindrical 8m6 ngu-φ8m6 (+0.015/+0.006);ukuphambuka okuphezulu kungu-+0.015, ukuphambuka okuphansi kungu-+0.006;usayizi womkhawulo omkhulu ngu-φ8.015, usayizi womkhawulo omncane ngu-φ8.006, futhi indawo yokubekezelela ngu-0.009.Ukubekezelela iphinikhodi yensimbi engagqwali eyi-cylindrical 10 h8 ingu-φ10 h8 (0/-0.022), ukuchezuka okuphezulu ngu-0, kanti ukuchezuka okuphansi kungu-0.022.Usayizi womkhawulo omkhulu ngu-φ10, usayizi womkhawulo omncane ngu-φ9.978, futhi indawo yokubekezelela ngu-0.022.Amaphini ngokuvamile asetshenziselwa ukuxhuma, ukukhiya izingxenye noma ukubeka umhlangano, futhi angasetshenziswa njengezingxenye zemishini yokuphepha.Izikhonkwane eziyi-cylindrical zilungiswa emigodini ngokuphazamisa ukulungisa izingxenye, ukudlulisa amandla, noma ukusebenza njengezingxenye zokumisa.Amaphinikhodi angama-cylindrical amaphini okumisa asetshenziselwa ukulungisa indawo ehlobene phakathi kwezingxenye.Kuyingxenye ebalulekile yokusiza lapho kuhlangene ukucubungula nokuhlanganisa.Izikhonkwane ze-cylindrical ngokuvamile zenziwe ngensimbi yekhwalithi ephezulu ye-carbon structural njengezinto zokusetshenziswa.Ngaphansi kwezimo ezijwayelekile, izinto zokwakha ngokuvamile ziyi-C35 ne-C45, kodwa ukwelashwa kokushisa kuyadingeka.Insimbi yokuthwala ikhethwa ngaphansi kwezidingo zamandla aphezulu.Insimbi engagqwali yenziwe ngokuyinhloko ngezinto ezingama-303 futhi ayidingi ukwelashwa okushisa.Iphinikhodi elinwebekayo eliyisilinda ngokuvamile lingama-65Mn.
Amahange alezi zinhlobo ezilandelayo:
(1) Ibhawodi yehange yokwandisa
Amabhawodi okunweba ihange, abizwa ngokuthi amabhawodi okunweba, sebenzisa ukunyakaza okuhlobene kwekhoni kanye neshidi lokunweba (noma umkhono wokunweba) ukuze kuthuthukiswe ukunwetshwa kweshidi lokunweba, kukhiqize amandla okunweba nawokunweba ngokhonkolo odongeni lwembobo, futhi kukhiqize amandla okunweba nawokunweba ngokhonkolo odongeni lwembobo. ukumelana nokukhipha nge-shear friction.Ingxenye eqaphela ukubambelela kwesiqephu esixhunyiwe.Amabhawodi okunweba ihange ahlukaniswe ngohlobo lokulawula i-torque kanye nohlobo lokulawula ukufuduka ngokuya ngezindlela ezihlukene zokulawula amandla okunweba ngesikhathi sokufakwa.Eyokuqala ilawulwa yi-torque, kanti eyesibili ilawulwa ngokususwa.
(2) Ibhawodi yehange yohlobo lokuphindayo
Amahange ohlobo oluvuzayo, abizwa ngokuthi ama-reaming bolt noma ama-grooving bolt, aphinde agxumeke futhi aphinde amise ukhonkolo ngaphansi kwembobo ebhoboliwe, kusetshenziswa ukuxhuma okuwumshini phakathi kwendawo ephethe ukhonkolo eyakhiwe ngemva kokuvuselelwa kabusha kanye nenhloko yokunweba yebhawodi lehange. ., ingxenye eqaphela ukubambelela kwesiqephu esixhunyiwe.Ama-reaming ama-anchor bolts ahlukaniswe abe-pre-reaming kanye nokuzivuselela ngokwawo ngezindlela ezihlukene zokuphinda zenziwe kabusha.Eyangaphambili i-pre-grooving futhi ivuselela ngethuluzi elikhethekile lokumba;umshudo wokugcina wehange ufika nethuluzi, elizikhukhumeza ngokwalo futhi lizibuyisela kabusha ngesikhathi sokufakwa, futhi ukugoba nokufakwa kuqedwa ngesikhathi esisodwa.
(3) Amabhawodi okusetshenzwa kulengwa aboshwe
Amabhawodi okusetshenzwa kwe-anchor ahlanganisiwe, aziwa nangokuthi amabhowudi okuqinisa amakhemikhali, abizwa ngokuthi amabhawudi amakhemikhali noma amabhowuthi okuqinisa, enziwe ngezinamatheliso zamakhemikhali ezikhethekile (iglue okunamathiselwe kwi-anchoring) ukuze kunamathiselwe futhi kulungiswe izikulufu namapayipi anentambo yangaphakathi emigodini yokubhoboza yama-substrates kakhonkolo.Umsebenzi wokuhlanganisa nokukhiya phakathi kwe-adhesive ne-screw kanye ne-adhesive kanye nodonga lwembobo kakhonkolo ukuze kubonakale ingxenye ehlanganiswe nesiqephu esixhunyiwe.
(4) Ukutshalwa kwemisipha ngamakhemikhali
Ibha yokutshala yamakhemikhali ihlanganisa ibha yensimbi enentambo kanye nenduku ende yesikulufu, okuwubuchwepheshe bokuxhuma ngemuva kwehange obusetshenziswa kakhulu emibuthanweni yobunjiniyela yezwe lami.Ukubambelela kwezinsimbi zokutshala amakhemikhali kuyafana nokuhlanganisa amabhawodi okunamathisela ihange, kodwa ngenxa yokuthi ubude bezinsimbi zokutshala amakhemikhali nezikulufu ezinde abunqunyelwe, bufana nokubambelela kwezinsimbi zikakhonkolo ezifakwe endaweni, kanye nefomu lomonakalo. kulula ukuyilawula, futhi ngokuvamile ingalawulwa njengokulimala kwezinsimbi zokusethula.Ngakho-ke, ilungele ukuxhunywa okuqinile kwamalungu esakhiwo noma amalungu angewona wesakhiwo ukuqina kwawo okuqinile nokuzamazama komhlaba kungaphansi noma okulingana no-8.
(5) Izikulufu zikakhonkolo
Isakhiwo kanye nendlela yokunamathisela yezikulufo zikakhonkolo zifana nezikulufu zokhuni.Inqubo ekhethekile isetshenziselwa ukugoqa nokucisha isikulufu sentambo esiqinile nesibukhali sommese.Ngesikhathi sokufakwa, imbobo eqondile ene-diameter encane i-pre-drilled, bese i-screw ifakwe ngaphakathi, kusetshenziswa intambo nembobo.Isenzo se-occlusal phakathi kokhonkolo odongeni sikhiqiza amandla okudonsa futhi sibona ingxenye ebambelele ezingxenyeni ezixhunyiwe.
(6) Ukudubula izinzipho
Izipikili zokudubula uhlobo lwezinzipho zensimbi ezinokuqina okuphezulu, okuhlanganisa izikulufu, ezishayelwa isibhamu, zibe ukhonkolo, futhi zisebenzisa izinga lokushisa eliphezulu (900 ° C) ukuze zenze izipikili zensimbi nokhonkolo kuhlanganiswe ngenxa yokuhlangana kwamakhemikhali nokubopha.Qaphela ukubambelela kwezingxenye ezixhunyiwe.
