Ukubekezelela nokutholwa kwe-threadbonding
Inhloso yalesi sahluko ukuqonda izici zokuguquguquka kwentambo evamile kanye nokusetshenziswa kwamazinga okubekezelelana.Isidingo sokufunda siwukuqonda umthelela wamaphutha amakhulu wejometri wentambo evamile ekushintsheni;Misa umqondo wobubanzi besenzo somucu;Ngokuhlaziya ukusatshalaliswa kwendawo yokubekezelela intambo, phatha kahle izici zokubekezelela intambo evamile kanye nokufaneleka kanye nokukhetha kokunemba kwentambo;Qonda izinto ezithinta ukunemba kokususwa kwesikulufu somshini.
Uhlobo lwentambo kanye nezidingo zokusebenzisa
1, intambo evamile
Ivamise ukubizwa nge-fastening thread, isetshenziswa ngokuyinhloko ukuxhuma nokubopha izingxenye ezihlukahlukene zemishini.Izidingo zokusetshenziswa kwalolu hlobo lokuxhuma okufakwe imicu yi-screwability (ukuhlanganiswa okulula nokuhlakazeka) nokuthembeka kokuxhuma.
2. Shayela intambo
Lolu hlobo lwentambo ngokuvamile lusetshenziselwa ukudlulisa ukunyakaza noma amandla.Ukusetshenziswa koxhumano olunentambo kudinga ukwethembeka kwamandla adlulisiwe noma ukunemba kokufuduka okudlulisiwe.
3. Intambo eqinile
Lolu hlobo lwentambo lusetshenziselwa ukuhlanganisa amalunga.Ukusetshenziswa kwezidingo zentambo kuqinile, akukho ukuvuza kwamanzi, akukho ukuvuza komoya futhi akukho ukuvuza kukawoyela.
Ukusingatha ingxabano
Uchungechunge lwangaphandle oluhlangabezana nemithetho ehambisanayo yokusetshenziswa kuThebula loku-1 lapho luhlolwa ngegeji yokukala indandatho yochungechunge oluphela kanye negeji yokukala indandatho yokuphela yaleli zinga, futhi luhlangabezana nemithetho ehambisanayo yokusebenzisa kuThebula u-Al lapho ihlolwa nge- through. -end smooth ring gauge (noma i-snap gauge) kanye ne-end-end smooth snap gauge (noma i-ring gauge) yaleli zinga, ibhekwa njengefanelekile.Uchungechunge lwangaphakathi oluthobela imithetho ehambisanayo yokusebenzisa kuThebula 1 uma ihlolwa nge i-plug gauge yokuqeda kanye ne-stop-end plug gauge yaleli zinga kanye nemithetho ehambisanayo yokusetshenziswa kuThebula u-Al lapho ihlolwa nge-plug gauge eshelelayo yokuqeda ukuphela kanye ne-plug gauge yokuqeda ebushelelezi ye-Appendix A yaleli zinga. uthathwa njengofanelekile.T.5 Ukuze kuncishiswe izingxabano ngesikhathi sokuhlolwa, isisebenzisi kufanele sisebenzise izikali ezintsha noma ezincane ezigugile kakhulu futhi ezigugile kakhulu noma eziseduze nomkhawulo wokuguga ngesikhathi sokwenza izintambo zokusebenza.Umnyango wokuhlola noma omele umsebenzisi uzosebenzisa igeji yentambo eguga kakhulu noma esondele kumkhawulo wokuguga kanye negeji yentambo yokuvala entsha noma encane lapho amukela uchungechunge lwe-T.1.6 Esimeni sengxabano ngesikhathi sokuhlolwa , uma i-gauge yentambo enquma intambo ye-workpiece okufanele ifaneleke ngokuhambisana nezinhlinzeko zaleli zinga, intambo ye-workpiece izobhekwa njengefanelekile.
Isilinganiso esisodwa
Ngemicu evamile yosayizi omkhulu, izintambo ezinembayo kanye nezintambo zokushayela, ngaphezu kokujikeleza nokuthembeka kokuxhumeka, kunezinye izidingo zokunemba nokusebenza, futhi isilinganiso esisodwa ngokuvamile sisetshenziswa ekukhiqizeni.
Ziningi izindlela zokukala intambo eyodwa, ejwayeleke kakhulu ukusebenzisa isibonakhulu sethuluzi lomhlaba wonke ukukala ububanzi, iphimbo kanye nengxenye ye-Engeli yochungechunge.I-microscope yethuluzi isetshenziselwa ukukhulisa iphrofayili yentambo elinganisiwe futhi ikalwe ukuphakama kwayo, i-Angle enguhhafu kanye nobubanzi obuphakathi ngokuvumelana nesithombe sentambo elinganisiwe, ngakho indlela ibizwa nangokuthi indlela yesithombe.
Ekukhiqizeni kwangempela, indlela yokulinganisa yezikhonkwane ezintathu isetshenziselwa ukukala ububanzi obuphakathi bomucu wangaphandle.Le ndlela ilula, inembile yokulinganisa futhi isetshenziswa kabanzi
Isifinyezo esifushane
1. Intambo evamile
(1) Amagama ayinhloko kanye nemingcele yejometri yezintambo ezijwayelekile yilezi: uhlobo lwamazinyo ayisisekelo, ububanzi obukhulu (D, d), ububanzi obuncane (D1, d1), ububanzi obuphakathi (D2, d2), ububanzi obuphakathi obusebenzayo, ububanzi obuphakathi obubodwa ( I-D2a, i-d2a) ububanzi bangempela obuphakathi, iphimbo (P), uhlobo lwezinyo I-engeli (a) nohlobo lwezinyo I-engeli enguhhafu (a/2), nobude bezikulufu.
(2) Umqondo wobubanzi obumaphakathi besenzo kanye nezimo ezifanelekayo ze-diameter ephakathiUbukhulu bobubanzi obuphakathi obusebenzayo buthinta i-spibility, futhi ubukhulu bobubanzi bangempela obuphakathi buthinta ukwethembeka koxhumano.Ukuthi i-diameter emaphakathi ifanelekile noma cha kufanele ilandele isimiso sika-Taylor, futhi kokubili ububanzi bangempela obumaphakathi kanye nobubanzi obuphakathi obusebenzayo kulawulwa ngaphakathi kwendawo yokubekezelela yobubanzi obuphakathi.
(3) Izinga elivamile lokubekezelela intambo Esilinganisweni sokubekezelela intambo, ukubekezelelwa kwe-d, d2 kanye no-D1, D2 kucacisiwe.Amazinga abo okubekezelelana aboniswa kuThebula 9-1.Akukho ukubekezelelana okucacisiwe kohlobo lwephimbo kanye nezinyo (okulawulwa indawo yokubekezelela ububanzi obuphakathi), futhi akukho ukubekezelelana okucacisiwe ku-diameter encane d yentambo yangaphandle kanye nobubanzi obukhulu D bentambo yangaphakathi.
(4) Ukuchezuka okuyisisekelo Emicu yangaphandle, ukuchezuka okuyisisekelo ukuchezuka okuphezulu (ama), kukhona u-e, f, g, h izinhlobo ezine;Ngemicu yangaphakathi, ukuchezuka okuyisisekelo ukuchezuka okuphansi (El), kunezinhlobo ezimbili zika-G kanye no-H. Ibanga lokubekezelela kanye nokuchezuka okuyisisekelo kuhlanganisa indawo yokubekezelela intambo.Izinga likazwelonke licacisa indawo evamile yokubekezelelana, njengoba kukhonjisiwe kuThebula 9-4.Ngokuvamile, indawo yokubekezelela ekhethwayo ecaciswe etafuleni kufanele ikhethwe ngokusemandleni.Ukukhethwa kwezindawo zokubekezelelana kuchazwe kulesi sahluko.
(5) Ubude be-screw kanye nebanga lokunembaUbude besikulufu buhlukaniswe ngezinhlobo ezintathu: ezifushane, eziphakathi nendawo nezinde, ezikhonjwa ngekhodi S, N kanye no-L, ngokulandelana.Amanani aboniswa kuThebula 9-5Uma ileveli yokubekezelela yochungechunge ilungisiwe, uma ubude be-screw, buphakama ukuchezuka kwephimbo okunqwabelene kanye nokuchezuka kwe-engeli uhhafu wezinyo.Ngakho-ke, intambo ngokwezinga lokubekezelela kanye nobude besikulufa inamazinga amathathu okunemba: ukunemba, okuphakathi nokumangelengele.Ukusetshenziswa kwezinga ngalinye lokunemba kuchazwe kulesi sahluko.Ngezinga elifanayo lokunemba, izinga lokubekezelela intambo kufanele lincishiswe ngokunyuka kobude bokuphotha (bheka Ithebula 9-4).
(6) Ukumakwa kwemicu emdwebeni kukhonjisiwe kokuqukethwe kulesi sahluko.
(7) Ukutholwa kwemicu kuhlukaniswe ukutholwa okuphelele nokutholwa okukodwa.
