Akakodzera kuverenga mafomula anoshandiswa mukugadzira fastener:
1. Kuverenga uye kushivirira kwekunze kweshinda pitch dhayamita ye60° mbiri (National Standard GB 197/196)
a. Kuverengera kwezviyero zvekutanga zve pitch dhayamita
Saizi yekutanga yeshinda inonamira dhayamita = shinda huru dhayamita - pitch × coefficient value.
Formula kutaura: d/DP×0.6495
Muenzaniso: Kuverengera kwepitch dhayamita yeM8 yekunze shinda
8-1.25×0.6495=8-0.8119≈7.188
b. Inowanzo shandiswa 6h yekunze shinda pitch dhayamita kushivirira (zvichibva papitch)
Muganho wepamusoro kukosha ndeye "0"
Iyo yakaderera muganho kukosha ndeye P0.8-0.095 P1.00-0.112 P1.25-0.118

Iyo yepasi muganho yekuverenga formula d-ges-Td ndiyo saizi yekutanga yedhayamita huru yeshinda - iyo datum kutsauka - kushivirira.
Muenzaniso: M8 yekunze shinda 6g giredhi guru dhayamita yepamusoro muganho kukosha φ8-0.028=φ7.972.
Lower muganhu kukoshaφ8-0.028-0.212=φ7.76
Ongorora: ① Iyo dhayamita hombe yeshinda inotarwa nedhayamita yetambo yakakwenenzverwa uye dhigirii rezino rinopfekwa neshinda inotenderedza ndiro/roller, uye kukosha kwayo kunopesana nepakati nepakati dhayamita yeshinda zvichienderana ne zvakafanana blank uye shinda kugadzirisa maturusi. Ndiko kuti, kana dhayamita yepakati iri diki, iyo dhayamita yakakura ichave yakakura, uye zvinopesana kana dhayamita yepakati yakakura, iyo dhayamita yakakura ichava diki.
② Kune zvikamu zvinoda kurapwa kwekupisa uye kurapwa kwepamusoro, tichifunga nezvekugadzirisa, dhayamita yeshinda inofanirwa kudzorwa kuti ive pamusoro peiyo yakaderera muganho wegiredhi 6h pamwe ne0.04mm panguva yekugadzira chaiyo. Semuenzaniso, tambo yekunze yeM8 iri kukwesha (kutenderera) Iyo dhayamita yakakura yetambo inofanira kunge iri pamusoro pe φ7.83 uye pasi pe7.95.
4. Kuverenga uye kushivirira kwemukati thread dhayamita
a. Basic size calculation yemukati tambo dhayamita (D1)
Saizi yekutanga = saizi yekutanga yeshinda yemukati - pitch × coefficient
Muenzaniso: Iyo yekutanga dhayamita yemukati shinda M8 ndeye 8-1.25 × 1.0825 = 6.646875≈6.647
b. Kuverengera kwediki dhayamita kushivirira (zvichienderana nepitch) uye diki dhayamita kukosha kwe6H yemukati shinda
P0.8 +0. 2 P1.0 +0. 236 P1.25 +0.265 P1.5 +0.3 P1.75 +0.335
P2.0 +0.375 P2.5 +0.48
Iyo yakaderera muganho yekutsauka formula ye6H giredhi yemukati shinda D1+HE1 ndiyo yakakosha saizi yemukati shinda diki dhayamita + kutsauka.
Ongorora: Kudzika kwakasarudzika kukosha kwenhanho 6H ndeye "0"
Iyo yekuverengera fomula yeyepamusoro muganhu kukosha kwegiredhi 6H shinda yemukati =D1+HE1+TD1, inova saizi yehukuru hwediki dhayamita yemukati shinda + kutsauka + kushivirira.
Muenzaniso: Muganho wepamusoro wedhayamita diki ye6H giredhi M8 shinda yemukati ndeye 6.647+0=6.647
Muganho wakaderera weiyo dhayamita diki ye6H giredhi M8 shinda yemukati ndeye 6.647+0+0.265=6.912
c. Kuverengera kwekutsauka kwekutanga kwediki dhayamita yemukati shinda 6G giredhi (zvichienderana nepitch) uye diki dhayamita kukosha.
P0.8 +0.024 P1.0 +0.026 P1.25 +0.028 P1.5 +0.032 P1.75 +0.034
P2.0 +0.038 P2.5 +0.042
Chimiro chemuganho wezasi wedhayamita diki ye6G giredhi shinda yemukati = D1 + GE1, inova saizi yekutanga yeshinda yemukati + kutsauka.
Muenzaniso: Muganho wezasi weiyo dhayamita diki ye6G giredhi M8 shinda yemukati ndeye 6.647+0.028 = 6.675
Iyo yepamusoro muganhu kukosha formula ye6G giredhi M8 yemukati shinda dhayamita D1+GE1+TD1 ndiyo yakakosha saizi yemukati shinda + kutsauka + kushivirira.
Muenzaniso: Muganho wepamusoro wedhayamita diki ye6G giredhi M8 shinda yemukati ndeye 6.647+0.028+0.265=6.94
Ongorora: ① Kureba kwetambo yemukati kune hukama zvakananga nenguva yekuremerwa yetambo yemukati, saka inofanirwa kunge iri mukati memuganho wepamusoro wegiredhi 6H panguva yekugadzira isina chinhu.
② Panguva yekugadziriswa kwetambo dzemukati, iyo diki dhayamita yeshinda yemukati ichave nemhedzisiro pakushandiswa kwakanaka kwechigadzirwa chekugadzira - pombi. Kubva pakuona kwekushandiswa, iyo diki dhayamita, zviri nani, asi kana uchifunga zvakazara, iyo dhayamita diki inowanzoshandiswa. Kana iri simbi yakakandwa kana aruminiyamu chikamu, muganho wakaderera kusvika kumuganhu wepakati weiyo dhayamita diki inofanira kushandiswa.
③ Iyo dhayamita diki yeshinda yemukati 6G inogona kuitwa se6H mukugadzirwa kusina chinhu. Chiyero chechokwadi chinonyanya kutarisisa kuvharwa kwedhayamita yeshinda. Naizvozvo, chete dhayamita yepitch yepombi inotariswa panguva yekugadzira shinda pasina kutarisisa dhayamita diki regomba rechiedza.
5. Calculation formula ye single indexing nzira ye indexing musoro
Calculation formula ye single indexing method: n=40/Z
n: inhamba yekuchinja kunofanirwa kutenderedzwa musoro unopatsanura
Z: chikamu chakaenzana cheworkpiece
40: Yakagadziriswa nhamba yekuparadzanisa musoro
Muenzaniso: Kuverengera kwehexagonal milling
Tsiva mune fomula: n = 40/6
Kuverenga: ① Rerutsa chikamu: Tsvaga diki diki divisor 2 woigovane, kureva, patsanura nhamba nedhinominata ne2 panguva imwe chete kuti uwane 20/3. Nepo kuderedza chikamu, zvikamu zvaro zvakaenzana zvinoramba zvisina kuchinjwa.
② Verenga chikamu: Panguva ino, zvinoenderana nehunhu hwenhamba uye denominator; kana nhamba nedhinominata zvakakura, verenga.
20÷3=6(2/3) ndiyo n kukosha, kureva kuti, musoro unopatsanura unofanira kushandurwa 6(2/3) nguva. Panguva ino, chikamu chava nhamba yakasanganiswa; chikamu chizere chenhamba yakasanganiswa, 6, ndiyo nhamba yekuparadzanisa Musoro unofanira kutendeuka 6 zvizere. Chikamu 2/3 chine chidimbu chinogona kungoita 2/3 chemugero mumwe chete, uye chinofanira kuverengerwa patsva panguva ino.
③ Kuverengera kwekusarudzwa kwendiro yekunongedza: Iko kuverenga kweisingasviki denderedzwa imwe kunofanirwa kuitika nerubatsiro rwe indexing plate yemusoro we indexing. Nhanho yekutanga mukuverenga ndeyekuwedzera chikamu 2/3 panguva imwe chete. Semuenzaniso: kana chikamu chacho chichiwedzerwa nguva gumi nemana panguva imwe chete, chikamu chiri 28/42; kana yakawedzerwa ka10 panguva imwe chete, mucherechedzo uri 20/30; kana yakawedzerwa ka13 panguva imwe chete, mucherechedzo uri 26/39… Kuwedzera kuwanda kwegedhi rinopatsanura kunofanira kusarudzwa zvichienderana nenhamba yemakomba mu indexing plate.
Panguva ino, unofanira kuteerera:
①Huwandu hwemaburi akasarudzwa ku indexing plate inofanira kupatsanurwa ne denominator 3. Semuenzaniso, mumuenzaniso wapfuura, 42 maburi ari 14 times 3, 30 maburi 10 times 3, 39 is 13 times 3…
② Kuwedzerwa kwechikamu kunofanira kunge kwakaita kuti nhamba nedhinominata zviwedzere panguva imwe chete uye zvikamu zvakaenzana zvirambe zvisina kuchinjwa, semumuenzaniso.
28/42=2/3×14=(2×14)/(3×14); 20/30=2/3×10=(2×10)/(3×10);
26/39=2/3×13=(2×13)/(3×13)
Denominator 42 ye28/42 inorongedzerwa uchishandisa maburi makumi mana nemaviri einhamba yenhamba; nhamba 28 iri kumberi pane buri rekumisikidza vhiri repamusoro uye yobva yatenderera nepaburi makumi maviri nemasere, kureva kuti, 29 buri ndiro buri rekumisikidza vhiri razvino, uye 20/30 iri pa30 Hole indexing plate inotenderedzwa kumberi. uye buri rechigumi kana buri rechigumi nerimwe ndiro buri rekumisa epicycle.
