Knurling (GB/T6403.3—1986)
Njira yogubuduza chithunzi pamwamba pa chogwirira ntchito ndi chida chomangira pa lathe imatchedwa knurling.Mtundu wopindika nthawi zambiri umakhala ndi mitundu iwiri ya njere zowongoka ndi ukonde, ndipo pali zokhuthala ndi zoonda.Kuchuluka kwa chitsanzo kumatsimikiziridwa ndi kukula kwa phula.
1.Mawonekedwe a knurling ndi mawonekedwe a knurling pattern
makulidwe a chitsanzo knurled ayenera kusankhidwa molingana ndi awiri a knurled pamwamba pa workpiece, lalikulu m'mimba mwake, lalikulu modulus chitsanzo;chocheperako m'mimba mwake, mawonekedwe ang'onoang'ono a modulus.
2.Chitsanzo cha chilemba chofunika pa knurling
①Modulus m = 0.2, ng'anjo yowongoka, chizindikiro chake ndi: mbewu zowongoka m=0.2 (GB6403.3-1986).
② Reticulate m = 0.3, reticulated knurling, chizindikiro chake ndi: reticulated m=0.3 (GB6403.3-1986).
3.Knurling processing
(1) Ikani chogwirira ntchito.Kuyika kuyenera kukhala kolimba momwe kungathekere.
① Mukayika chogwirira ntchito, kutalika kwa chuck chotuluka chiyenera kukhala chachifupi kwambiri.
②Chogwirira ntchito chachitali chimathandizidwa ndi pamwamba.
③Mukatembenuza bwalo lakunja la gawo lopindika, m'mimba mwake liyenera kukhala lochepera 0.25mm kuposa kukula komaliza.
(2) Ikani mpeni wokhomerera.
①Yang'anani ngati tchipisi todulira pa mpeni wakupukusa tatsuka.Ngati ndi kotheka, gwiritsani ntchito burashi yawaya kuti muyeretse.
②Mukayika chodulira chokhotakhota, pini ya pivot iyenera kulumikizidwa kuti ichite ndi ngodya pang'ono.
④ Gwirani chidacho mwamphamvu.
(3) Kubowoleza kogwirira ntchito.
①Sankhani liwiro lotsika komanso chakudya chachikulu.
②Yambitsani spindle ya chida cha makina ndikuyika zoziziritsa kukwanira pa chida chokhotakhota.
③Gwirani mpeni wokhotakhota kuti mudule chogwirira ntchito ndikukakamiza mpaka mtundu wa diamondi wochuluka upangike.
④ Dyetsani mpeni mopingasa ndikuudyetsa motalika mpaka kutalika kofunikirako kupezeke.
⑤ Gwirani mpeni wokhomedwa kuti muchoke mwachangu.
(4) Kusokoneza.
Pamapeto a chogwirira ntchito, ma burrs amachotsedwa podula chamfer ya 45 ° yomwe imafika pansi pa poyambira.Mtima ndi wapamwamba.
③ Sinthani mpeni wokhotakhota mowoneka, ndikuwupotoza pang'ono pang'ono kuti muwunikire mosavuta.
④ Gwirani chidacho mwamphamvu.
