Ukunyamezela kunye nokufumanisa ukudibanisa intambo
Injongo yesi sahluko kukuqonda iimpawu zokuguquguquka kwentambo eqhelekileyo kunye nokusetyenziswa kwemigangatho yokunyamezela.Imfuno yokufunda kukuqonda impembelelo yeempazamo eziphambili zejometri zomsonto oqhelekileyo ekutshintsheni;Ukuseka ingqikelelo yedayamitha yentshukumo yomsonto;Ngokuhlalutya ukuhanjiswa kwendawo yokunyamezela intambo, lawula iimpawu zokunyamezela intambo eqhelekileyo kunye nokufaneleka kunye nokukhethwa kokuchaneka kwentambo;Qonda izinto ezichaphazela ukuchaneka kokufuduswa kwesikrufu somatshini.
Uhlobo lwentambo kunye neemfuno zokusetyenziswa
1, intambo eqhelekileyo
Ngokuqhelekileyo ibizwa ngokuba yintambo yokudibanisa, isetyenziselwa ukudibanisa kunye nokudibanisa iindawo ezahlukeneyo zoomatshini.Iimfuno zokusetyenziswa kolu hlobo loxhumo oludibeneyo luyi-screwability (indibano elula kunye ne-disassembly) kunye nokuthembeka koqhagamshelwano.
2. Qhuba umsonto
Olu hlobo lwentambo ludla ngokusetyenziselwa ukuhambisa intshukumo okanye amandla.Ukusetyenziswa koxhumo lwentambo kufuna ukuthembeka kwamandla adlulisiweyo okanye ukuchaneka kokufuduswa okugqithisiweyo.
3. Umsonto oqinileyo
Olu hlobo lwentambo lusetyenziselwa ukutywina amalunga.Ukusetyenziswa kweemfuno zentambo ziqinile, akukho manzi avuzayo, akukho moya ovuzayo kwaye akukho mafutha avuzayo.
5. Umlinganiselo womsonto
1. Umlinganiselo obanzi
Ukujonga intambo ngegeyiji yomsonto ngumlinganiselo obanzi.Kwimveliso yebhetshi, intambo eqhelekileyo isetyenziswa indlela yokulinganisa ebanzi.Umlinganiselo obanzi wenziwa kusetyenziswa igeyiji yomsonto (i-gauge yokulinganisa ebanzi) ngokwemigaqo yokufaneleka komgangatho womsonto owaziswa ngaphambili (umgaqo kaTaylor). Igeyiji yomsonto yahlulwe yaba “yigeyiji yokudlula” kunye “negeyiji yokuyeka”.Xa uvavanya, "i-pass gauge" inokuphumelela ngempumelelo nge-workpiece, kwaye "i-stop gauge" ayikwazi ukukrazula okanye i-screw engaphelelanga, ngoko intambo ifanelekile.Ngokuphambene noko, "i-pass gauge" ayikwazi ukujikelezwa, ebonisa ukuba i-nut incinci kakhulu, i-bolt inkulu kakhulu, kwaye intambo kufuneka ilungiswe.Xa "i-stop gauge" inokudlula kwi-workpiece, ithetha ukuba i-nut inkulu kakhulu, i-bolt incinci, kwaye intambo iyimveliso yenkunkuma.
2. Ukubhaqwa komntu omnye
(1) Ukulinganisa ububanzi bomsonto ngendlela yeepin-ntathuIndlela yezikhonkwane ezintathu isetyenziswa ikakhulu ukulinganisa idiamitha ephakathi echanekileyo yokuchaneka kwemisonto yangaphandle (efana neegeyiji zeplagi yentambo, iintambo zokujija zelothe, njl. njl.).Ngexesha lokulinganisa, beka iinaliti ezintathu zokulinganisa ezichanekileyo ezinobubanzi obufanayo kwigrooves yomsonto olinganisiweyo ngokulandelelana, kwaye usebenzise isixhobo sokulinganisa i-optical okanye umatshini ukulinganisa umgama wenaliti M, njengoko kubonisiwe kuMfanekiso 9-9 (a).Ngokutsho kwepitch eyaziwayo yeP yomsonto olinganisiweyo kunye nesiqingatha se-Angle a/2 yohlobo lwezinyo, i-d2 ephakathi kwedayamitha ephakathi yomsonto olinganisiweyo ibalwa ngokucinezela ifomula.
2. Umlinganiselo omnye
Ubukhulu obukhulu bemisonto eqhelekileyo, imicu echanekileyo kunye neentambo zokuqhuba, ngaphezu kokujikeleza kunye nokuthembeka koxhumo, kukho ezinye iimfuneko zokuchaneka kunye nokusebenza, kwaye umlinganiselo omnye usetyenziswa ngokubanzi kwimveliso.
Zininzi iindlela zokulinganisa intambo enye, eyona iqhelekileyo kukusebenzisa isixhobo se-universal microscope ukulinganisa ububanzi, i-pitch kunye nesiqingatha se-Engile yomsonto.Isixhobo se-microscope sisetyenziselwa ukwandisa iphrofayili yomsonto olinganisiweyo kunye nokulinganisa i-pitch yayo, isiqingatha se-Angle kunye ne-diameter ephakathi ngokomfanekiso womsonto olinganisiweyo, ngoko ke indlela ibizwa ngokuba yindlela yomfanekiso.
Kwimveliso yangempela, indlela yokulinganisa i-pin ezintathu isetyenziselwa ukulinganisa ububanzi obuphakathi bomsonto wangaphandle.Le ndlela ilula, iphezulu yokulinganisa ichanekile kwaye isetyenziswa ngokubanzi
Isishwankathelo esifutshane
1. Intambo eqhelekileyo
1 I-D2a, i-d2a) i-diameter yokwenyani ephakathi, i-pitch (P), uhlobo lwezinyo i-Engile (a) kunye nohlobo lwezinyo lwesiqingatha se-Engile (a/2), kunye nobude be-screw.
(2) Ingcamango yobubanzi obuphakathi besenzo kunye neemeko ezifanelekileyo zomda ophakathi
Ubungakanani bobubanzi obuphakathi obusebenzayo buchaphazela i-spinability, kwaye ubungakanani bobukhulu bokwenene obuphakathi buchaphazela ukuthembeka koqhagamshelwano.Ukuba i-diameter ephakathi ifanelekile okanye ayifanele ilandele umgaqo we-Taylor, kwaye zombini i-diameter ephakathi kunye ne-diameter ephakathi esebenzayo ilawulwa ngaphakathi kwendawo yokunyamezela ye-diameter ephakathi.
(3) Inqanaba eliqhelekileyo lokunyamezela intambo Kumgangatho wokunyamezela intambo, ukunyamezela kwe-d, d2 kunye ne-D1, i-D2 kucacisiwe.Amanqanaba abo okunyamezelana aboniswe kwiThebhile 9-1.Akukho unyamezelo luchaziwe pitch kunye nodidi izinyo (ukulawulwa yi zone unyamezelo ephakathi ububanzi), kwaye akukho unyamezelo luchazwe kwidayamitha encinane d intambo yangaphandle kunye nedayamitha enkulu D yomsonto wangaphakathi.
(4) Ukutenxa okusisiseko Kwimisonto yangaphandle, ukutenxa okusisiseko kukutenxa okuphezulu (ii), kukho u-e, f, g, h iindidi ezine;Kwimisonto yangaphakathi, ukutenxa okusisiseko kukutenxa okusezantsi (El), kukho iindidi ezimbini ze-G kunye ne-H. Ibakala lokunyamezela kunye nokutenxa okusisiseko kubumba indawo yokunyamezela intambo.Umgangatho wesizwe uchaza indawo yokunyamezela eqhelekileyo, njengoko kubonisiwe kwiThebhile 9-4.Ngokubanzi, indawo yokunyamezela ekhethiweyo echazwe kwitheyibhile kufuneka ikhethwe kangangoko kunokwenzeka.Ukukhethwa kwemimandla yokunyamezela kuchazwe kwesi sahluko.
(5) Ubude bekrikri kunye nebakala elichanekileyo
Ubude be-screw screw buhlukaniswe kwiintlobo ezintathu: ezimfutshane, eziphakathi kunye nezide, ezichazwe yikhowudi S, N kunye ne-L, ngokulandelanayo.Amaxabiso aboniswe kwiThebhile 9-5
Xa inqanaba lonyamezelo lomsonto lilungisiwe, okukhona ubude be-screw, ukuphakama kokutenxa kwepitch eqokelelweyo kunye nesiqingatha sezinyo ukutenxa kwe-engile kunokubakho.Ngoko ke, intambo ngokwenqanaba lokunyamezela kunye nobude be-screw inamanqanaba amathathu achanekileyo: ukuchaneka, okuphakathi kunye nokukrakra.Ukusetyenziswa kwenqanaba ngalinye lokuchaneka kuchazwe kwesi sahluko.Ngomgangatho ofanayo wokuchaneka, umgangatho wokunyamezela umsonto kufuneka uncitshiswe kunye nokunyuka kobude be-spinning (jonga iThebhile 9-4).
(6) Ukumakishwa kwemisonto kumzobo kubonisiwe kwiziqulatho ezifanelekileyo zesi sahluko.
(7) Ukufunyaniswa kwemisonto kwahlulahlulwe kubhaqo olubanzi kunye nobhaqo olulodwa.
