Ntchito ndi ubwino wa machining center atatu-axis:
Tiye ogwira kwambiri Machining pamwamba pa ofukula Machining pakati (atatu-olamulira) ndi pamwamba pamwamba pa workpiece, ndi yopingasa Machining likulu akhoza kokha kumaliza anayi mbali Machining wa workpiece mothandizidwa ndi tebulo rotary.Pakalipano, malo opangira makina apamwamba akukula motsogozedwa ndi kayendetsedwe ka ma olamulira asanu, ndipo workpiece ikhoza kukonzedwa mu clamping imodzi.Ngati okonzeka ndi mkulu-mapeto dongosolo CNC ndi kugwirizana asanu olamulira, angathenso kuchita mkulu-mwatsatanetsatane Machining pa malo ovuta malo.
Kodi makina anayi ogwirizana nthawi imodzi ndi chiyani?
Makina otchedwa four-axis munthawi imodzi amawonjezera nsonga yozungulira, yomwe nthawi zambiri imatchedwa axis yachinayi.Chida chachikulu cha makina chili ndi nkhwangwa zitatu zokha, ndiye kuti nsanja yogwirira ntchito imatha kusuntha kumanzere ndi kumanja (1 olamulira), kutsogolo ndi kumbuyo (2 olamulira), ndipo mutu wa spindle (3 olamulira) umagwiritsidwa ntchito podula zida.Mutu wolozera wamagetsi wozungulira!Mwanjira iyi, mabowo a bevel amatha kulembedwa molunjika, ndipo m'mphepete mwa beveled amatha kuphwanyidwa, etc., popanda kutayika kolondola ndi kumenyedwa kwachiwiri.
Makina olumikizirana ma-axis anayi:
(1).Makina opanga makina olumikizirana ma axis atatu sangathe kukonzedwa kapena amafunika kumangirizidwa motalika kwambiri
(2).Limbikitsani kulondola, khalidwe ndi luso la malo aulere
(3).Kusiyana pakati pa olamulira anayi ndi olamulira atatu;kusiyana kwa ma axis anayi ndi ma axis atatu okhala ndi nsonga imodzi yozungulira.Kukhazikitsidwa kwa ma 4-axis coordinates ndi kuyimira ma code:
Kutsimikiza kwa Z-axis: mayendedwe a olamulira a chida cha makina opota kapena njira yowongoka ya tebulo logwirira ntchito kuti agwire ntchitoyo ndi Z-axis.Kutsimikiza kwa X-olamulira: yopingasa ndege kufanana workpiece okwera pamwamba kapena malangizo perpendicular kwa kasinthasintha olamulira workpiece mu yopingasa ndege ndi X-olamulira.Mayendedwe akutali ndi ozungulira ozungulira ndi njira yabwino.
Malo opangira makina okwana asanu agawidwa kukhala malo opangira makina osakanikirana ndi olamulira asanu ndi malo opingasa amitundu isanu.Kodi makhalidwe awo ndi otani?
Oyima asanu-axis Machining Center
Pali mitundu iwiri ya ma rotary axis amtundu uwu wa makina opanga makina, imodzi ndi yozungulira patebulo.
Zogwiritsira ntchito pabedi zimatha kuzungulira X-axis, yomwe imatanthauzidwa ngati A-axis, ndipo A-axis nthawi zambiri imakhala ndi madigiri +30 mpaka -120 madigiri.Palinso tebulo lozungulira pakati pa tebulo logwiritsira ntchito, lomwe limazungulira kuzungulira Z-axis pamalo omwe akuwonetsedwa mu chithunzicho, chomwe chimatanthauzidwa ngati C-axis, ndipo C-axis imazungulira madigiri 360.Mwa njira iyi, kupyolera mu kuphatikiza kwa Axis ndi C axis, workpiece yokhazikika patebulo ikhoza kukonzedwa ndi spindle yowongoka kupatula pansi pamtunda, malo ena asanu.Mtengo wocheperako wa A-axis ndi C-axis nthawi zambiri ndi madigiri 0.001, kotero kuti chogwiriracho chikhoza kugawidwa mu ngodya iliyonse, ndi malo ozungulira, mabowo, ndi zina zotero.
Ngati A-axis ndi C-axis alumikizidwa ndi XYZ mizere itatu ya mzere, malo ovuta amatha kukonzedwa.Inde, izi zimafuna chithandizo cha machitidwe apamwamba a CNC, machitidwe a servo ndi mapulogalamu.Ubwino wa dongosololi ndikuti mapangidwe a spindle ndi osavuta, kulimba kwa spindle ndikwabwino kwambiri, ndipo mtengo wopangira ndi wotsika.
Koma ambiri, worktable sangakhoze kupangidwa lalikulu kwambiri, ndi kunyamula mphamvu ndi yaing'ono, makamaka pamene A-olamulira kasinthasintha wamkulu kuposa kapena wofanana ndi madigiri 90, workpiece kudula kubweretsa lalikulu katundu nthawi worktable.
Kumapeto kwa shaft yayikulu ndi mutu wozungulira, womwe umatha kuzungulira Z axis 360 madigiri ndikukhala C axis.Mutu wozungulira ulinso ndi axis A yomwe imatha kuzungulira X axis, nthawi zambiri kuposa ± 90 madigiri, kuti ikwaniritse ntchito yomweyi pamwambapa.Ubwino wa njira yokhazikitsira iyi ndikuti kukonza kwa spindle ndikosavuta kwambiri, ndipo chogwirira ntchito chimatha kupangidwanso kuti chikhale chachikulu kwambiri.Gulu lalikulu la ndege zonyamula anthu komanso chosungira chachikulu cha injini zitha kukonzedwa pamtundu woterewu wamachining.
Mbali yopingasa asanu olamulira Machining pakati
Palinso njira ziwiri zokhotakhota zamtundu uwu wa makina opangira makina.Imodzi ndi yakuti spindle yopingasa imasinthasintha ngati axis yozungulira, kuphatikiza ndi nsonga yozungulira ya chogwirira ntchito kuti ikwaniritse kukonza kolumikizana kwa ma axis asanu.Njira yokhazikitsira iyi ndi yosavuta komanso yosinthika.Ngati spindle ikufunika kusinthidwa molunjika ndi mopingasa, tebulo logwirira ntchito likhoza kusinthidwa kukhala malo opangira makina atatu ozungulira ndi opingasa pokhapokha polozera ndi kuikapo.The ofukula ndi yopingasa kutembenuka kwa shaft waukulu amagwirizana ndi indexing ya worktable kuzindikira pentahedral processing wa workpiece, amene amachepetsa kupanga mtengo ndi zothandiza kwambiri.CNC nkhwangwa angathenso anapereka pa worktable, ndi osachepera index mtengo wa madigiri 0,001, koma popanda kugwirizana, amakhala anayi olamulira pakati Machining kwa ofukula ndi yopingasa kutembenuka, kuzolowera zofunika zosiyanasiyana processing, ndipo mtengo ndi mpikisano kwambiri.
Wina ndi wozungulira wachikhalidwe wa tebulo logwirira ntchito.The A-axis ya worktable yoikidwa pa bedi nthawi zambiri imakhala yogwira ntchito ya madigiri +20 mpaka -100 madigiri.Palinso tebulo lozungulira B-axis pakati pa tebulo, ndipo B-axis imatha kuzungulira madigiri 360 mbali zonse ziwiri.Malo opingasa a ma axis asanu ali ndi mikhalidwe yabwino yolumikizirana kuposa njira yoyamba, ndipo nthawi zambiri amagwiritsidwa ntchito pokonza malo opindika azinthu zazikulu.Ma rotary axis amathanso kukhala ndi mayankho ozungulira, ndipo kulondola kwa indexing kumatha kufika masekondi angapo.Zoonadi, kapangidwe kake kozungulira kameneka kamakhala kovutirapo komanso kokwera mtengo.
Ambiri mwa malo Machining akhoza cholinga kusinthanitsa worktables iwiri.Pamene worktable amathamanga m'dera processing, ena worktable m'malo workpiece kunja kwa malo processing kukonzekera processing wa workpiece lotsatira.Nthawi ya kusinthanitsa worktable zimadalira worktable.Kukula, kuyambira masekondi angapo mpaka makumi amasekondi kuti amalize.
