1. Mamiriro Ekuita Eworkpiece
Chimiro che workpiece yakaonda-yakavezwamavhiri anoremachimiro chefani, zvinhu iQT600, kuoma kuri 187-255 HBW, mukati igomba rakasarudzika, uye chikamu chakatetepa chingori 4 mm mukobvu. Zvidimbu zvedimensional accuracy zvinodiwa zvebhanhire rekuenzanisa zvinoratidzwa muMufananidzo 1. Kureba kwepakati pegomba B bhenji ndeye Φ69.914-69.944 mm, uye kushivirira ndeye 0.03 mm chete. Pazasi pane buri rakanyorwa. Kucheka kwepakati kunoitwa kana uchigadzira C referensi gomba uye denderedzwa rekunze. Ukobvu hwemadziro pano ndeye 4 mm chete, iyo iri nyore kugadzira kutema kushushikana uye deformation uye inokanganisa saizi yekushivirira yeB referenzi gomba, inova nzvimbo yakaoma mukugadzirisa workpiece.
2. Dzakavanzika Ngozi Dzechinyakare Craft
Zvikamu zvakatetepa-madziro zvinoremara zviri nyore panguva yekugaya, zvakanyanya nekuda kweiyo deformation inokonzerwa nekucheka kushushikana uye clamping. Iyo yechinyakare yekugadzirisa chirongwa inogadziriswa neCNC machining Center uye CNC lathe, iyo yakakamurwa kuita maviri maitiro. Imwe ndeye OP10 maitiro. Shandisa Φ60 mm dhisiki yekuchekesa kuita kushata uye kupedzisa ndege yepamusoro kusvika pakukura kwekudhirowa, shandisa Φ20 mm alloy milling cutter kune rough pakugaya mukati meburi Φ51.04-51.07 mm kusvika Φ50.7 mm (siya 0.3-0.4 mm), shandisa Φ20 mm Alloy milling cutter rough yemukati meburi Φ69.914～69.944 mm kusvika Φ69.6 mm (kusiya 0.3～0.4 mm), gomba remukati rakanaka Φ51.04～51.07 mm uye 9 Φ49 mm. nemucheki wakanaka unoboora, dhiraivha 2 ×Φ18 mm nemaburi madiki maviri. Yechipiri ndiyo OP20 maitiro. Denderedzwa rekunze "C" rekushanya uye kutendeuka kwakanaka kune zvinodiwa zvehunyanzvi zvekudhirowa.
Kuoma kwekugadzira kwemavhiri anorema, gomba rereferenzi B, rakagadzirwa kune saizi inodiwa nedhirowa muchirongwa cheOP10. Bvisa workpiece uye kuyera dhayamita yereferensi gomba B, Φ69.914 ~ 69.944 mm, uye ovality kukanganisa ndeye 0.005 ~ 0.015 mm, uye saizi inosangana nezvinodiwa zvekudhirowa. Zvisinei, mushure mokunge OP20 yagadziriswa, bvisa workpiece uye kuyera dhayamita yegomba rereferensi reB, Φ69.914-69.944 mm, uye kukanganisa kwe ovality ndeye 0.03-0.04 mm. Zvinogona kuonekwa kuti dhayamita yakapfuura zvinodiwa pakudhirowa .
3. Solution
Kuvandudza tooling. Kunyangwe dhizaini yechishandiso chekusunga iri chokwadi ine chekuita nekuona machining echokwadi cheiyo workpiece, kuvandudza kugadzirwa kwevashandi uye kuderedza kuwanda kwevashandi. Nekuda kwehunhu hwezvikamu zvakatetepa-madziro, yakawandisa clamping simba kana isina kuenzana simba inokonzeresa elastic deformation yeworkpiece, izvo zvinokanganisa kurongeka kwehukuru uye chimiro kushivirira kwechikamu, uye pakupedzisira kutungamira kune saizi yechikamu chakagadziriswa. nokuda kwokushivirira. Kuti ugadzirise dambudziko iri, modhi uye saizi ye clamping cylinder uye cylinder yekutsigira inofanirwa kusarudzwa kana uchigadzira iyo hydraulic tooling.
