1. Nā hiʻohiʻona o ka mea hana
ʻO ke ʻano o ka mea hana i ka paia lahilahinā paona huilahe ʻano peʻa, ʻo QT600 ka mea, ʻo 187-255 HBW ka paʻakikī, ʻo loko he puka kūikawā, a ʻo ka ʻāpana lahilahi he 4 mm wale nō ka mānoanoa. Hōʻike ʻia nā koi kikoʻī o ka poloka kaulike ma ke Kiʻi 1. ʻO ke anawaena o ka lua waena B benchmark he Φ69.914-69.944 mm, a ʻo ka hoʻomanawanui he 0.03 mm wale nō. Aia ma lalo kahi puka hakahaka. Hana ʻia ka ʻoki ʻana i ka wā e mīkini ana i ka lua kuhikuhi C a me ka pōʻai waho. ʻO ka mānoanoa o ka pā ma ʻaneʻi he 4 mm wale nō, he mea maʻalahi ke hoʻoulu i ke kaumaha a me ka deformation a pili i ka nui o ka hoʻomanawanui o ka lua kuhikuhi B, he wahi paʻakikī ia i ka hana ʻana i nā mea hana.
2. Nā pōʻino huna o ka hana kuʻuna
Hoʻololi maʻalahi nā ʻāpana ʻāpana ʻāpana i ka wā o ke kaʻina wili, ma muli o ka deformation i hoʻokumu ʻia e ka ʻoki ʻana i ke kaumaha a me ka hoʻopili ʻana. Hoʻoponoponoʻia ka papahana hana maʻamau e CNC machining center a me CNC lathe, i māheleʻia iʻelua kaʻina hana. ʻO kekahi ke kaʻina hana OP10. E hoʻohana i ka mea ʻoki wili diski Φ60 mm e ʻokiʻoki a hoʻopau i ka mokulele luna e like me ka nui o ke kaha kiʻi, e hoʻohana i ka mea ʻoki wili wili Φ20 mm i ka wili wili i ka lua i loko Φ51.04-51.07 mm a i Φ50.7 mm (haʻalele 0.3-0.4 mm), e hoohana i ka Φ20 mm Alloy milling cutter rough milling ill hole Φ69.914～69.944 mm a i Φ69.6 mm (waiho 0.3～0.4 mm), Φ51.04～51.07 mm a me Φ49.6 mm. me ka ʻoki ʻoki maikaʻi, e wili i 2 ×Φ18 mm me ʻelua puka liʻiliʻi. ʻO ka lua ka hana OP20. ʻO ka pōʻai waho "C" o ka huli ʻana a me ka maikaʻi e pili ana i nā koi ʻenehana o ke kaha kiʻi.
ʻO ka paʻakikī o ka mīkininā paona huila, ka puka kuhikuhi B, ua mīkini ʻia i ka nui i koi ʻia e ke kaha kiʻi ma ke kaʻina hana OP10. Wehe i ka mea hana a ana i ke anawaena o ka puka kuhikuhi B, Φ69.914~69.944 mm, a o ka hewa ovality he 0.005~0.015 mm, a ua like ka nui i na koi o ke kaha kii. Eia naʻe, ma hope o ka hana ʻia ʻana o ka OP20, wehe i ka mea hana a ana i ke anawaena o ka lua kuhikuhi o B, Φ69.914-69.944 mm, a ʻo ka hewa ovality ʻo 0.03-0.04 mm. Hiki ke ʻike ʻia ua ʻoi aku ke anawaena ma mua o nā koi o ke kaha kiʻi.
3. Hoʻonā
E hoʻomaikaʻi i nā mea hana. Inā pololei ka hoʻolālā ʻana o ka mea hoʻopaʻa paʻa i ka hopena pololei i ka hōʻoia ʻana i ka pololei o ka mīkini o ka mea hana, ka hoʻomaikaʻi ʻana i ka hana hana a me ka hōʻemi ʻana i ka ikaika o nā limahana. Ma muli o nā hiʻohiʻona o nā ʻāpana ʻāpana lahilahi, ʻoi aku ka ikaika o ka hoʻopili ʻana a i ʻole ka ikaika ʻole e hoʻoneʻe i ka elastic deformation o ka mea hana, e pili ana i ka pololei o ka nui a me ke ʻano hoʻomanawanui o ka ʻāpana, a ma hope e alakaʻi i ka nui o ka ʻāpana i hana ʻia. no ka hoomanawanui. I mea e hoʻoponopono ai i kēia pilikia, pono e koho pono ʻia ke kumu hoʻohālike a me ka nui o ka cylinder clamping a me ke kākoʻo cylinder i ka wā e hoʻolālā ai i ka mea hana hydraulic.
