Zida zamakina a CNC zikukula molunjika, kuthamanga kwambiri, pawiri, nzeru komanso kuteteza chilengedwe. Makina olondola komanso othamanga kwambiri amaika zofuna zapamwamba pagalimoto ndi kuwongolera kwake, mawonekedwe apamwamba kwambiri komanso kuwongolera kolondola, kuchuluka kwa chakudya komanso kuthamangitsa, phokoso locheperako komanso kuvala kochepa. The crux wa vuto ndi kuti chikhalidwe kufala unyolo kwa galimoto monga gwero mphamvu kwa mbali ntchito kudzera magiya, magiya nyongolotsi, malamba, zomangira, couplings, zowomba ndi zina wapakatikati kufala maulalo, mu maulalo awa anatulutsa inertia lalikulu rotational. , zotanuka mapindikidwe, backlash, kuyenda hysteresis, mikangano, kugwedera, phokoso ndi kuvala. Ngakhale m'maderawa kudzera patsogolo mosalekeza kupititsa patsogolo ntchito kufala, koma vuto n'kovuta kwenikweni kuthetsa, mu zikamera wa lingaliro la "kufala mwachindunji", ndiko kuti, kuchotsa maulalo osiyanasiyana wapakatikati kuchokera galimoto kupita ku mbali zogwirira ntchito. . Ndi chitukuko cha ma motors ndi luso lawo loyendetsa galimoto, ma spindles amagetsi, ma linear motors, ma torque motors komanso kukula kwa teknoloji, kotero kuti spindle, mizere ndi rotary zimagwirizanitsa kayendetsedwe ka "direct drive" kuti ikhale yeniyeni, ndikuwonetsa mochulukirachulukira. ukulu wake waukulu. Linear motor ndi ukadaulo wake wowongolera pamakina opangira zida zamakina pakugwiritsa ntchito, kotero kuti makina otumizira chida chakhala kusintha kwakukulu ndikupanga kudumpha kwatsopano pamakina.
TheMayiAubwino waLineMotorFeedDmtsinje:
Kuthamanga kosiyanasiyana kwa chakudya: Kungakhale kuchokera ku 1 (1) m / s kufika ku 20m / min, malo opangira makina othamanga kwambiri afika 208m / min, pamene chida chamakono chimathamanga <60m / min. Nthawi zambiri 20 ~ 30m / min.
Makhalidwe abwino othamanga:Kupatuka kwa liwiro kumatha kufika (1) 0.01% kapena kuchepera.
Kuthamanga kwakukulu: Linear motor pazipita mathamangitsidwe mpaka 30g, panopa Machining pakati chakudya mathamangitsidwe wafika 3.24g, laser processing makina chakudya mathamangitsidwe wafika 5g, pamene chikhalidwe makina chida mathamangitsidwe mathamangitsidwe 1g kapena zochepa, zambiri 0.3g.
Kulondola kwa malo apamwamba : Kugwiritsa ntchito grating yotseka-loop control, kuyika kulondola mpaka 0.1 ~ 0.01 (1) mm. kugwiritsa ntchito njira yoyendetsera kutsogolo kwa linear motor drive system kumatha kuchepetsa zolakwika zotsata nthawi zopitilira 200. Chifukwa cha mawonekedwe abwino osunthika a magawo osuntha komanso kuyankha tcheru, kuphatikizidwa ndi kuwongolera kwa kutanthauzira, kuwongolera kwa nano-level kumatha kukwaniritsidwa.
Kuyenda sikuli ndi malire : Kuyendetsa kwachikhalidwe kwa mpira kumachepa ndi kupanga wononga, nthawi zambiri 4 mpaka 6m, ndipo zikwapu zambiri zimafunika kulumikiza wononga yayitali, zonse kuchokera pakupanga ndi momwe zimagwirira ntchito sizoyenera. Kugwiritsa ntchito liniya yamagalimoto oyendetsa, stator imatha kukhala yayitali kwambiri, ndipo njira yopangira ndiyosavuta, pali makina akulu othamanga kwambiri X-axis mpaka 40m kutalika kapena kupitilira apo.
Kupita patsogolo kwaLineMotor ndiIts DmtsinjeCkulamuliraTzamakono:
Ma Linear motors ndi ofanana ndi ma motors wamba kwenikweni, ndikungokulira kwa cylindrical pamwamba pagalimoto, ndipo mitundu yake ndi yofanana ndi ma motors achikhalidwe, monga: DC linear motors, AC maginito okhazikika maginito liniya motors, AC induction asynchronous ma motors ozungulira, ma stepper linear motors, etc.
Monga liniya servo galimoto kuti akhoza kulamulira kulondola kuyenda anaonekera mu 1980s mochedwa, ndi chitukuko cha zipangizo (monga okhazikika maginito zipangizo), zipangizo mphamvu, luso kulamulira ndi ukadaulo womvera, ntchito liniya servo Motors akupitiriza kusintha, mtengo ukuchepa, kupanga mikhalidwe kwa ntchito yawo ponseponse.
M'zaka zaposachedwa, makina opangira ma liniya ndi ukadaulo wake wowongolera pagalimoto akupita patsogolo m'magawo otsatirawa: (1) magwiridwe antchito akupitilizabe kuyenda bwino (monga kuthamanga, kuthamanga, kuthamanga, kukonza, etc.); (2) kuchepetsa voliyumu, kuchepetsa kutentha; (3) zosiyanasiyana Kuphunzira kukwaniritsa zofunika mitundu yosiyanasiyana ya zida makina; (4) kutsika kwakukulu kwa mtengo; (5) unsembe mosavuta ndi chitetezo; (6) kudalirika kwabwino; (7) kuphatikiza machitidwe a CNC Muukadaulo wothandizira akukhala wangwiro; (8) digiri yapamwamba yamalonda.
Pakali pano, otsogola padziko lonse lapansi a linear servo motors ndi makina awo oyendetsa ndi: Siemens;Japan FANUC, Mitsubishi; Anorad Co.(USA), Kollmorgen Co.; ETEL Co. (Switzerland) ndi zina.
