Zida za shaft monga crankshafts, camshafts, ndi cylinder liners zama injini zimagwiritsa ntchito chucks pokonza. Pakukonza, ma chucks ali ndi ntchito zoyika pakati, kuwongolera ndi kuyendetsa chogwirira ntchito. Malinga ndi kuthekera kwa chuck kugwira chogwirira ntchito ndikusunga pakati, chimagawidwa kukhala chuck yolimba ndi chuck yoyandama. Nkhaniyi ikufotokoza makamaka mfundo zosankhidwa ndi zosamalira tsiku ndi tsiku za chucks ziwirizi.5aixs cnc Machining magawo
Ma chucks okhwima ndi ma chucks oyandama ndi osiyana kwambiri pamapangidwe ndi njira yosinthira. Kutenga ma chucks angapo a mtundu waku Japan mwachitsanzo, Chithunzi 1 chikuwonetsa momwe chuck yoyandama imagwirira ntchito: chogwiriracho chili pansi pa chotchinga chothandizira ndi pamwamba. Axial ndi radial positioning ndi clamping zimachitika, ndiyeno silinda ya chuck imayendetsa ndodo ya chuck center, mbale yosinthira gap, mbale yothandizira nsagwada, mgwirizano wozungulira ndi mkono wa nsagwada kudzera pa ndodo, ndipo pamapeto pake amazindikira nsagwada ya chuck kuti igwire. workpiece. .
Pamene pali kupatuka kwakukulu kwa coaxiality pakati pa nsagwada zitatu za chuck ndi pakati pa workpiece, nsagwada ya chuck yomwe imakhudzana ndi workpiece choyamba idzagonjetsedwa ndi mphamvu F2, yomwe imaperekedwa ku nsagwada. mbale yothandizira mkono kudzera mumkono wa nsagwada ndi malo ozungulira. F3 imagwira pa mbale yothandizira ya claw mkono. Kwa chuck yoyandama, pali kusiyana pakati pa ndodo yapakati ya chuck ndi mbale yothandizira mkono. Pansi pa mphamvu ya F3, mbale yothandizira claw mkono imagwiritsa ntchito choyandama choyandama (mbale yosinthira gap, ndodo yapakati ya chuck ndi mbale yothandizira ya mkono wa nsagwada palimodzi zimapanga njira yoyandama ya chuck), yomwe imasuntha. kumbali ya mphamvu mpaka nsagwada zitatu kwathunthu atsekeretse workpiece.

Kuchokera pakuwunika kwa makina a chuck mu Chithunzi 1 ndi Chithunzi 2, chuck yoyandama ndi chuck yolimba imakhala ndi zosiyana zotsatirazi.
Kuyandama chuck: Monga momwe chithunzi 3, m'kati clamping workpiece, chifukwa cha kutalika osiyana workpiece akusowekapo pamwamba kapena lalikulu roundness kulolerana opanda kanthu, ndi No. 3 nsagwada adzakumana ndi workpiece pamwamba ndi nsagwada za nambala 1 ndi nambala 2 zidzawonekera. Ngati workpiece sichinakhudzidwebe, panthawiyi, njira yoyandama ya chuck yoyandama imagwira ntchito, pogwiritsa ntchito pamwamba pa workpiece monga chithandizo choyandama nsagwada No. Malingana ngati kuchuluka koyandama kuli kokwanira, nsagwada za nambala 1 ndi nambala 2 pamapeto pake zidzatsekedwa. Chogwirira ntchito chimakhala ndi zotsatira zochepa pakatikati pa workpiece.
Chithunzi 3 Kutsekereza nsagwada zoyandama za chuck
Olimba chuck: Monga momwe chithunzi 4, pa ndondomeko clamping, ngati concentricity pakati chuck ndi workpiece si kusintha bwino, nsagwada No. 3 adzalumikizana workpiece, ndi No. 1 ndi No. 2 nsagwada sadzatero. kukumana ndi workpiece. , ndiye chuck clamping mphamvu F1 idzachitapo kanthu pa workpiece. Ngati mphamvuyo ndi yayikulu mokwanira, chogwiriracho chidzachotsedwa ku malo okonzedweratu, kukakamiza workpiece kupita pakati pa chuck; pamene clamping mphamvu ya chuck ndi yaing'ono, zina zidzachitika. Pamene nsagwada sangathe mokwanira kukhudzana workpiece, kugwedezeka kumachitika pa Machining.cnc mphero cholumikizira
Chithunzi 4 Kumanga kwa nsagwada zolimba za chuck
Zofunikira zosintha chuck isanayambe kugwiritsidwa ntchito: Chuck yolimba ipanga malo otsekera a chuck yokhayo pambuyo pomenya. Mukamagwiritsa ntchito chuck yolimba, ndikofunikira kusintha malo otsekera a chuck kuti agwirizane ndi malo omangira ndi malo ogwirira ntchito, monga momwe tawonetsera pachithunzi 5.cnc Machining aluminiyamu gawo
Chithunzi 5 Kusintha kwa malo okhwima a chuck
Malinga ndi kusanthula kwamapangidwe omwe ali pamwambapa, tikulimbikitsidwa kutsatira mfundo zotsatirazi pakuwongolera ndi kukonza chuck: Mafuta ndi mafuta azinthu zosunthika mkati mwa chuck amasinthidwa pafupipafupi. Kuyenda pakati pa magawo omwe akuyenda mkati mwa chuck kwenikweni ndikugwedezeka. Ndikofunikira kuwonjezera ndikusintha nthawi zonse kalasi yamafuta opaka mafuta / mafuta molingana ndi zofunikira pakukonza chuck. Mukawonjezera mafuta, ndikofunikira kufinya mafuta onse omwe adagwiritsidwa ntchito m'mbuyomu, kenako ndikutsekereza khomo lotulutsa mafuta mukamamanga chuck kuti mutseke mkati mwa chuck kuti asabwerere.
Kuyang'ana nthawi zonse ndikusintha malo okhomerera a chuck olimba komanso pakatikati pa chogwirira ntchito: Chuck yolimba imayenera kuyeza nthawi ndi nthawi ngati pakati pa chuck ndi pakati pa chopondera chogwirira ntchito ndizofanana. Yezerani kuthamanga kwa disc. Ngati ipitilira mulingo wofunikira, onjezani ma spacers moyenera pansagwada imodzi kapena ziwiri zomwe zikugwirizana ndi malo okwera, ndikubwereza masitepe omwe ali pamwambawa mpaka zofunikira zitakwaniritsidwa.
Kuwunika kwanthawi ndi nthawi kuchuluka kwa chuck yoyandama (onani Chithunzi 6). Pokonza chuck tsiku lililonse, ndikofunikira kuyeza kuchuluka koyandama komanso kuyandama kwa chuck yoyandama, ndikupereka chitsogozo pakukonza mkati mwa chuck pambuyo pake. Njira yoyezera yoyandama mwatsatanetsatane: chuck ikamangirira chitsanzo, ikani chuck kuti ayezedwe. Tembenuzani chikhadabocho pamalo oyenera kuyeza, yesani chizindikiro choyimba (chofunika kumangitsa maginito mita pansi pa shaft yomwe ikuyenda), ndipo chongani poyezera ngati zero point. Kenako lamulirani nsonga ya servo kuti musunthe chizindikiro choyimba, tsegulani chuck, ikani gasket yokhala ndi makulidwe a Amm pakati pa nsagwada kuti muyesedwe ndi chitsanzo, ikani chitsanzo pa chuck, sunthani chizindikiro choyimba pamalo a zero, ndi kutsimikizira ngati deta mbamuikha ndi oyimba chizindikiro ndi za Amm. Ngati ndi choncho, ndiye kuti kulondola koyandama ndikwabwino. Ngati deta imasiyana kwambiri, zikutanthauza kuti pali vuto ndi makina oyandama a chuck. Muyeso wa nsagwada zina ndi wofanana ndi pamwambapa.
Chithunzi 6 Kuyang'ana kuchuluka koyandama kwa chuck yoyandama
Kusinthidwa pafupipafupi kwa magawo monga zisindikizo, ma gaskets ndi akasupe mkati mwa chuck: akasupe amakona anayi, thupi la chuck, chivundikiro chakumbuyo chakumbuyo, akasupe amakona anayi ndi zisindikizo ndi akasupe pazothandizira zozungulira ziyenera kuchitika molingana ndi kuchuluka kwa ntchito komanso mayeso omwe ali pamwambapa. zotsatira. Bwezerani pafupipafupi, apo ayi zidzawonongeka chifukwa cha kutopa, zomwe zimabweretsa kuchuluka koyandama komanso kutha kwa chuck.
Kupyolera mu kusanthula pamwamba pa mfundo zazikulu za kusintha kwa kamangidwe ka chuck ndi kukonza, tcherani khutu ku mfundo zotsatirazi posankha ma chucks: ngati chuck clamping gawo la gawo lokonzedwa ndi lopanda kanthu, chuck yoyandama imakonda, ndipo yolimba. chuck imagwiritsidwa ntchito mu workpiece. Pamwamba pa chuck clamping ya gawo lopangidwa ndi makina ndi pamwamba pambuyo pa roughing, semi-finishing/finishing. Pambuyo potsatira malamulo ofunikira omwe ali pamwambawa, ndikofunikira kupanga zosankha zenizeni malinga ndi momwe ntchito zikuyendera.
Kusankhidwa kwa chuck yolimba: ①Mapangidwe a makina amafunikira kudula kwakukulu komanso mphamvu yayikulu yodulira. Pambuyo clamped ndi workpiece kuti kukonzedwa ndi kuthandizidwa ndi chimango chapakati, amphamvu workpiece rigidity ndi lalikulu workpiece rotational galimoto amafunikira. ②Pakakhala palibe njira imodzi yokhazikika ngati pamwamba, ndipo mapangidwe a chuck centering amafunikira.
Kusankha kwa chuck yoyandama: ①Zofunika kwambiri pakatikati pa chopondera chopondera. Chuck ikamangidwa, kuyandama kwake sikungasokoneze malo oyambira a spindle. ②Kuchuluka kwa kudula sikuli kwakukulu, ndipo kumangofunika kuyendetsa spindle ya workpiece kuti izungulire ndikuwonjezera kulimba kwa workpiece.
Zomwe zili pamwambazi zikufotokozera kusiyana kwapangidwe, kukonza ndi kusankha zofunikira za chucks zoyandama komanso zolimba, zomwe zimathandiza kugwiritsa ntchito ndi kukonza ma chucks. Ngati mukufuna kumvetsetsa mozama komanso kugwiritsa ntchito mosinthika, muyenera kufotokozera mwachidule zomwe mwakumana nazo pakugwiritsa ntchito ndi kukonza patsamba.
