Chii chinonzi eccentric parts?
Eccentric parts inhengo dzemakanika dzine off-center axis of rotation kana chimiro chisina kujairika chinoita kuti dzitenderere zvisina kufanana. Zvikamu izvi zvinowanzo shandiswa mumakina uye masisitimu emuchina panodiwa mafambiro chaiwo uye kutonga.
Mumwe muenzaniso wakajairika wechikamu cheeccentric ndeye eccentric cam, inova denderedzwa disc ine protrusion pamusoro payo inoita kuti ifambe nenzira isina kufanana sezvainotenderera. Eccentric zvikamu zvinogona zvakare kureva kune chero chikamu chakagadzirirwa nemaune kutenderera kubva-pakati, senge vhiri rinobhururuka rine kusaenzana kugovera kwehuwandu.
Eccentric zvikamu zvinowanzo shandiswa mumashandisirwo akadai seinjini, pombi, uye maconveyor masisitimu panodiwa mafambiro chaiwo uye kutonga. Ivo vanogona kubatsira kuderedza vibration, kuvandudza mashandiro, uye kuwedzera hupenyu hwemuchina.
Nhanganyaya
Mumagetsi ekufambisa, eccentric zvikamu senge eccentric workpieces kana crankshafts anowanzo shandiswa kupedzisa basa rekuchinjana pakati pekufamba kwekutenderera uye kudzoreredza kufamba, saka eccentric zvikamu zvinoshandiswa zvakanyanya mukutapurirana kwemuchina. Iyo nhanho ye eccentric zvikamu zvekugadzirisa tekinoroji (kunyanya hombe eccentric workpieces) inogona kuratidza machining tekinoroji kugona kwebhizinesi.
Eccentric workpieces inoita basa rakakosha mukugadzirwa chaiko uye hupenyu. Mukufambisa kwemakanika, kushandura kutenderera kuita mutsetse kana kushandura mutsara kufamba kuita kutenderera kunopedzwa ne eccentric workpieces kana crankshafts. Semuyenzaniso, pombi yemafuta ekuzora mubhokisi rekupinza inofambiswa ne eccentric shaft, uye kutenderera kwe crankshaft yemota uye tarakita kunofambiswa nekudzokorodza mutsara kufamba kwepiston.
Matemu ehunyanzvi/mazita
1) Eccentric workpiece
Chishandiso chine matemo edenderedzwa rekunze uye denderedzwa rekunze kana denderedzwa rekunze negomba remukati zvakaenzana asi zvisina tsaona inova eccentric workpiece.
2) Eccentric shaft
Chishandiso chine matemo edenderedzwa rekunze uye denderedzwa rekunze zvakaenzana uye zvisina tsaona inonzi eccentric shaft.
3) Eccentric sleeve
Chishandiso chine matemo edenderedzwa rekunze negomba remukati zvakaenzana asi zvisina tsaona inonzi eccentric sleeve.
4) Eccentricity
Mune eccentric workpiece, chinhambwe chiri pakati peaxis ye eccentric chikamu uye axis yereferensi chikamu chinonzi eccentricity.
Iyo matatu-shaya inozvimisa-center chuck inokodzera eccentric workpieces isingade yakakwira kutendeuka, diki eccentric chinhambwe, uye hurefu hupfupi. Kana uchitendeuka, iyo eccentricity ye workpiece inovimbiswa nehupamhi hwe gasket yakaiswa pashaya.
Kunyangwe iyo yechinyakare nzira dzekugadzirisa eccentricCNC machining zvikamuuye yakagadziridzwa matatu-shay kutendeuka nzira inogona kupedza basa rekugadzirisa eccentric workpiece zvikamu, kukanganisa kwekuoma kwakaoma, kushanda kwakaderera, kuchinjana uye kunyatsoita zvakaoma kuvimbisa. Mazuva ano high-efficiency uyehigh-precision machiningpfungwa haigoni kushivirira.
Iyo Nheyo, Nzira uye Mapoinzi eKucherechedzwa kweEccentricity yeTatu-shaya Chuck
Nheyo yeiyo eccentricity yeshayi-matatu chuck: gadzirisa nzvimbo yekutenderera yenzvimbo yebasa kuti igadziriswe kuti ive concentric neakisi yemuchina wekushandisa spindle. Gadzirisa iyo geometric centroid yechikamu chinosungirira kusvika kureba kubva kune spindle axis yakaenzana ne eccentricity.
Gasket ukobvu kuverenga (yekutanga, yekupedzisira) l Gasket ukobvu hwekuverenga fomula: x=1.5e+k apo:
e-workpiece eccentricity, mm;
k——Kururamisa kukosha (kwakawanikwa mushure mekuedzwa, kureva, k≈1.5△e), mm;
△e—chikanganiso chiri pakati pechiyereso chakayerwa uye kuenzana kunodiwa mushure mekuita bvunzo (kureva △e=ee kuyerwa), mm;
e chiyero - iyo yakayerwa eccentricity, mm;
Muenzaniso 1
Kushandura workpiece ne eccentricity ye 3mm, kana hupamhi hwegasket huchishandurwa nechisarudzo chekuedza, iyo yakayerwa eccentricity ndeye 3.12mm, uye kukosha kwakarurama kwehupamhi hwegasket inowanikwa. l Solution: Ukobvu hweyedzo gasket ndeiyi:
X=1.5e=1.5×3mm=4.5mm
△e=(3-3.12)mm=-0.12mm
K=1.5△e=1.5×(-0.12)mm=-0.18mm
Zvinoenderana neformula: x=1.5e+k=(4.5-0.18) mm=4.32mm
Iko kukosha kweiyo gasket ukobvu ndeye 4.32mm.
Muenzaniso 2
Gasket rine ukobvu hwe10mm rinoshandiswa kushandura eccentric workpiece pane shaya pedhi yetatu-shaya self-centering chuck. Mushure mekutendeuka, iyo eccentricity yeworkpiece inoyerwa kuita 0.65mm idiki pane inodiwa dhizaini. Tsvaga iyo chaiyo kukosha kweiyo gasket ukobvu.
Inozivikanwa eccentricity kukanganisa △e = 0.65mm
Yakaenzana gasket ukobvu: X bvunzo = 1.5e = 10mm
K=1.5△e=1.5×0.65mm=0.975mm
Zvinoenderana neformula: x=1.5e+k=(10+0.975)mm=10.975mm
Iko kukosha kweiyo gasket ukobvu ndeye 10.975mm.
Kuipa kwe eccentric matatu-shaya kutendeuka
Eccentric-three-shaw turning, inozivikanwawo se eccentric chucking, inzira yekutenderedza apo workpiece inobatwa muchuck ine shaya nhatu dzisina pakati nepakati neaxis yechuck. Pane kudaro, imwe yeshaya inoiswa kure-pakati, ichigadzira eccentricrotation yeworkpiece.
Nepo eccentric matatu-shayi kutendeuka kune zvimwe zvakanakira, sekugona kutenderedza zvimiro zvakaumbwa uye kudzikisira kudiwa kwehunyanzvi maturusi, ine zvakare yakashata, kusanganisira:
1. lnaccurate centering: Nekuda kwekuti workpiece yakabatwa kure-pakati, zvinogona kunetsa kunyatsoiisa pakati payo kuitira chaiwo machining mashandiro. Izvi zvinogona kuguma nezvikamu zvisiri kushivirira kana kuti zvine nzvimbo dzisina kuenzana.
2. Yakaderedzwa simba rekubata: Iyo yepakati-yepakati shaya ine simba shoma rekubata kupfuura the2other maviri shaya, izvo zvinogona kuita kuti ive shoma yakachengeteka kubata pane workpiece. Izvi zvinogona kuita kuti workpiece ishanduke kana kutsvedza panguva yekugadzira, zvichitungamira kune kucheka kusiri iko uye mamiriro angangoita njodzi.
3. Kuwedzera kwechishandiso kupfeka: Nekuti iyo workpiece haina pakati, chishandiso chekucheka chinogona kusangana nekupfeka zvisina kuenzana, izvo zvinogona kuguma nehupenyu hupfupi hwematurusi uye kuwedzera mutengo wekutsiva chishandiso.
4. Zvishomanana zvakasiyana-siyana zvezvikamu: Eccentric chucking inowanzoenderana nediki to4.medium-sized parts, uyecnc kutendeuka chikamuane chimiro chenguva dzose. Iyo inogona kunge isingakodzere zvidimbu zvakakura kana zvakanyanya kuomarara, sezvo shaya yepakati inogona kusapa rubatsiro rwakakwana.
5. Yakarebesa kuseta nguva: Kumisikidza chuck ye eccentric kutendeuka kunogona kutora nguva yakawanda pane kuseta yakajairwa chuck, sezvo inoda nekungwarira positioning ofthe off-center jaw kuti uwane eccentricity yaunoda.
MuCNC Lathe, iyo eccentric zvikamu zvinogadzirwa nekugadzira chikamu pane alathe uchishandisa yakakosha eccentric chuck kana chigadziriso chinobata chikamu kubva-pakati.
Aya anotevera matanho akajairwa ekugadzira eccentric zvikamu muCNC lathe:
1. Sarudza yakakodzera eccentric chuck kana fixture inokodzera workpiece uye inobvumira
eccentricity yaidiwa.
2. Gadzirisa lathe ne chuck kana fixture uye uise workpiece zvakachengeteka.
3. Shandisa software yelathe kuseta iyo yekubvisa kune eccentricity yaunoda.
4. Ronga CNC muchina kuti ucheke chikamu maererano nedhizaini yaunoda, kuve nechokwadi chekuzvidavirira kweiyo offset munzira yekucheka.
5. Ita chirongwa chekuedza kuti uone kuti chikamu chiri kutemwa nemazvo uye kuti eccentricity iri mukati mekuda kushivirira.
6. Ita chero zvigadziriswa zvakakosha purogiramu yekucheka kana kugadzirisa kuti uwane migumisiro yaunoda.
7. Ramba uchicheka chikamu kusvikira chapera, uchiita kuti nguva nenguva utarise eccentricity uye uite chero zvigadziriswa zvinodiwa.
Pakazere, kugadzira eccentric zvikamu muCNC lathe zvinoda kunyatsoronga uye kunyatsoita kuti uve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nezvinodiwa.
Zvinyorwa zviri pamusoro zvakapihwa chete nechikwata cheAnebon, kukanganisa kunofanirwa kuongororwa
Anebonikambani inogadzira yakavakirwa muShenzhen, China iyo inonyanya kupa macustomized CNC machining services. Iyo kambani inopa huwandu hwakasiyana hwekugadzira masevhisi, anosanganisira CNC kugaya, kutendeuka, kuchera, nekukuya, pamwe nekurapa kwepamusoro uye masevhisi egungano.
Anebon ine ruzivo rwekushanda nezvinhu zvakasiyana siyana, zvinosanganisira aruminiyamu, ndarira, simbi isina tsvina, titanium, uye mapurasitiki, uye inogona kugadzira zvikamu zvine majeometri akaoma uye kushivirira kwakasimba. Iyo kambani inoshandisa michina yemhando yepamusoro, senge 3-axis uye 5-axis CNC michina, pamwe nemidziyo yekuongorora, kuona zvigadzirwa zvemhando yepamusoro.
Pamusoro peCNC machining masevhisi, Anebon inopawo prototyping masevhisi, ichibvumira vatengi kukurumidza kuyedza uye kukwenenzvera magadzirirwo avo vasati vatamira mukugadzirwa kwakawanda. Iyo kambani inodada nekuzvipira kwayo kune sevhisi yevatengi uye mhando, uye inoshanda padhuze nevatengi kuona kuti zvavanoda uye zvavanoda zvinosangana.
