1. Makhalidwe a Kapangidwe ka Ntchito
Mawonekedwe a workpiece yopyapyalazolemera zamawiloNdi mawonekedwe a fan, zinthu zake ndi QT600, kuuma kwake ndi 187-255 HBW, mkati mwake muli dzenje looneka ngati lapadera, ndipo gawo lopyapyala kwambiri ndi 4 mm yokha. Zofunikira pakulondola kwa balance block zikuwonetsedwa pa Chithunzi 1. M'mimba mwake mwa dzenje lapakati B benchmark ndi Φ69.914-69.944 mm, ndipo kulolerana kwake ndi 0.03 mm yokha. Pansipa pali dzenje lopanda kanthu lokhala ndi profile. Kudula kwapakati kumachitika pokonza dzenje la C ndi bwalo lakunja. Kukhuthala kwa khoma pano ndi 4 mm yokha, zomwe ndizosavuta kupanga kupsinjika ndi kusintha kwa kudula ndikukhudza kukula kwa dzenje la B, lomwe ndi lovuta pokonza workpiece.
2. Zoopsa Zobisika za Ntchito Zachikhalidwe
Zigawo zopyapyala zimawonongeka mosavuta panthawi yopangira mphero, makamaka chifukwa cha kusintha komwe kumachitika chifukwa cha kudula ndi kukakamiza. Njira yopangira mphero yachikhalidwe imakonzedwa ndi malo opangira machining a CNC ndi lathe ya CNC, yomwe imagawidwa m'njira ziwiri. Chimodzi ndi njira ya OP10. Gwiritsani ntchito chodulira chodulira cha Φ60 mm kuti mugwire bwino ndikumaliza gawo lapamwamba mpaka kukula kwa chojambula, gwiritsani ntchito chodulira chodulira cha Φ20 mm kuti mugwire bwino dzenje lamkati Φ51.04-51.07 mm mpaka Φ50.7 mm (siyani 0.3-0.4 mm), gwiritsani ntchito chodulira chodulira cha Φ20 mm Alloy milling bowo lamkati Φ69.914～69.944 mm mpaka Φ69.6 mm (siyani 0.3～0.4 mm), dzenje lodulira laling'ono Φ51.04～51.07 mm ndi Φ69.914～69.944 mm ndi chodulira chodulira pang'ono, bowolani 2 ×Φ18 mm ndi mabowo awiri ang'onoang'ono. Chachiwiri ndi njira ya OP20. Bwalo lakunja "C" la kutembenuza kodulira pang'ono ndi kosalala likugwirizana ndi zofunikira zaukadaulo za chojambulacho.
Kuvuta kwa makina azolemera zamawilo, dzenje lofotokozera B, linapangidwa molingana ndi kukula komwe kumafunika ndi kujambula mu ndondomeko ya OP10. Chotsani chogwirira ntchito ndikuyesa kukula kwa dzenje lofotokozera B, Φ69.914~69.944 mm, ndipo cholakwika cha ovality ndi 0.005~0.015 mm, ndipo kukula kwake kukukwaniritsa zofunikira za chojambula. Komabe, OP20 ikakonzedwa, chotsani chogwirira ntchito ndikuyesa kukula kwa dzenje lofotokozera la B, Φ69.914-69.944 mm, ndipo cholakwika cha ovality ndi 0.03-0.04 mm. Zikuoneka kuti kukula kwake kwapitirira zofunikira za chojambula.
3. Yankho
Konzani bwino zida. Kaya kapangidwe ka chipangizo cholumikizira ndi kolondola kakhudza mwachindunji kuwonetsetsa kuti ntchito yogwirira ntchito ikulondola, kukonza bwino ntchito komanso kuchepetsa mphamvu ya ogwira ntchito. Chifukwa cha makhalidwe a ziwalo zoonda, mphamvu yochulukirapo yolumikizira kapena mphamvu yosagwirizana imayambitsa kusintha kwa elasticity ya ntchitoyo, zomwe zidzakhudza kulondola kwa kukula ndi mawonekedwe a gawolo, ndipo pamapeto pake zimapangitsa kuti kukula kwa gawo lokonzedwa kusakhale kovomerezeka. Pofuna kuthetsa vutoli, chitsanzo ndi kukula kwa silinda yolumikizira ndi silinda yothandizira ziyenera kusankhidwa mosamala popanga zida zolumikizira zamagetsi.
