Makina akuya-dzenje trepanning TK2150
I. Basic ndondomeko ntchito makina
1) Makinawa amatha kugwiritsidwa ntchito popanga mabowo amkati.
2) Pamakina, workpiece imazungulira, chida chodulira chimadyetsa, ndipo Kudula madzimadzi kumalowa m'dera lodulira kudzera mu bar ya trepanning kuti kuziziritsa ndi kudzoza malo odulira ndikuchotsa zitsulo zachitsulo.
3) Pamene trepanning, kumbuyo kumbuyo kwa trepanning bar amagwiritsidwa ntchito popereka mafuta, ndipo kumapeto kwa mutu wopondereza mafuta kumagwiritsidwa ntchito podula.
6) Kulondola kwa makina opangira makina:

III.Magwiridwe ndi mawonekedwe a makina:
TK2150 CNC trepanning makina ndi chida chapadera makina pokonza cylindrical dzenje zakuya.
Panthawi yopangira trepanning, zoziziritsa kukhosi zimaperekedwa kuchokera kumapeto kwenikweni kwa trepanning bar, ndipo kumapeto kwa mafuta kumutu kumakhala ndi nyali yodulira.Zoyenera kupanga zambiri ndipo zitha kugwiritsidwanso ntchito kupanga chidutswa chimodzi komanso kupanga batch yaying'ono.
IV.dongosolo lalikulu la makina
1) Chida chamakina chimapangidwa ndi zinthu zazikulu monga bedi, mutu, chishalo, chodyeramo, kupumula kokhazikika, chotsitsa chotsitsa chokhazikika cha trepanning bar, makina oziziritsa, magetsi, chipangizo chochotsa chitsulo, ndi zina zambiri.
2) Bedi, chishalo, chishalo, bokosi, mutu woponderezedwa wamafuta, chothandizira ndi zinthu zina zonse zimapangidwa ndi chitsulo champhamvu kwambiri komanso nkhungu yamchenga wa resin, kuwonetsetsa kulimba, mphamvu, ndi kusungidwa kolondola kwa chida cha makina.Bedi limakhala lozimitsa nyimbo zapamwamba kwambiri padziko lonse lapansi, ndikuya kwa 3-5mm ndi HRC48-52, komwe kumakhala kukana kuvala kwambiri.
(1) Bedi
Bedi la chida cha makina limapangidwa ndi kuphatikiza zidutswa zitatu za matupi a bedi.Thupi la bedi ndi mawonekedwe okhala ndi mbali zitatu zotsekedwa ndi nthiti zokhotakhota, ndipo amapangidwa ndi chitsulo chapamwamba kwambiri cha HT300 chokhazikika bwino.M'lifupi mwa njanji yowongolera bedi ndi 800mm, yomwe ndi njira yathyathyathya komanso V-kalozera yokhala ndi mphamvu zonyamula katundu komanso kulondola kolondola.Njira yolondolerayo idalandira chithandizo chozimitsa ndipo ili ndi kukana kwamphamvu kwambiri.M'mphepete mwa njira yolondolera bedi, zomangira za mpira wa chakudya zimayikidwa, zothandizidwa ndi mabatani mbali zonse ziwiri ndikuthandizidwa ndi mafelemu awiri okoka pakati.Chojambula chokoka chimatha kuyenda motsatira njira yolondolera pansi pa poyambira, ndipo kuyenda kwake ndi kuyima kumayendetsedwa ndi kukoka mbale ndi zogudubuza pa chishalo.Pakhoma lakutsogolo kwa bedi pali poyambira ngati T, wokhala ndi mpando wokhazikika wa vibration damper wokhazikika wa bar wotopetsa, komanso mpando wokhazikika wa chishalo kuti ulamulire momwe kugwedezeka kwa bar ndi chishalo chokhazikika.Khoma lakutsogolo la bedi lili ndi ma rack omwe amalumikizana ndi magiya a chida chamanja kuti asunthire mpumulo wokhazikika, wothandizira, ndi chotsitsa chotsitsa cha vibration chokhazikika cha bar yotopetsa.
(2) Mutu:
Zokhazikika kumapeto kumanzere kwa bedi, bore la spindle ndi φ 130mm.Mutu wamutu umayendetsedwa ndi injini ya 30kW, ndipo liwiro la spindle ndi 3.15-315r / min kupyolera muzitsulo zochepetsera masitepe ambiri komanso kusintha kwapamanja ndi kutsika.Ikani chuck ya nsagwada zinayi kumapeto kwa spindle yamutu kuti mutseke chogwirira ntchito.
Mutuwu uli ndi makina odziyimira pawokha kuti apereke mafuta olimba amitundu yosiyanasiyana komanso ma giya awiri.
(3）Chishalo ndi mutu ulendo
Mutu waulendo umakhazikika pa chishalo, ndipo panthawi ya kudyetsa, mutu wa ulendo (wokhazikika kumbuyo kwa bedi) umayendetsa screw kuti azungulire, kuchititsa kuti mtedza wokhazikika ndi chishalocho usunthire axially, kuyendetsa chishalo kuti chidye.Chishalo chikamayenda mwachangu, mota yothamanga kuseri kwa chishalo imayendetsa chochepetsera liwiro kuti chizungulire, ndikuyendetsa chishalocho kuti chisunthe mwachangu.
Mutu woyendayenda wakhazikika pa chishalo.Ntchito yayikulu ndikumangirira kapamwamba ndikuyendetsa kutsogolo ndi kumbuyo kudzera pachishalo.
(4）Bokosi la chakudya
Bokosi la chakudya limayikidwa kumapeto kwa bedi ndipo limayendetsedwa ndi AC servo motor.The linanena bungwe olamulira akhoza kukwaniritsa stepless liwiro lamulo la 0.5-100r/mphindi.Mafuta mkati mwa bokosi amaperekedwa ndi plunger pampu yoyendetsedwa ndi kamera.Pali cholumikizira chachitetezo pakulumikizana pakati pa shaft yotulutsa ndi screw, ndipo mphamvu yolumikizira imatha kusinthidwa ndi akasupe.Ikadzaza, clutch imasiya ndipo microswitch imayambitsidwa kutumiza chizindikiro kuti chiyimitse chishalo (chiwonetsero chowonetsa cholakwika)
(5）Kupumula kokhazikika ndi jack of workpiece
Kupumula kosasunthika kumagwiritsa ntchito zodzigudubuza zitatu zokhala ndi mayendedwe odzigudubuza monga chothandizira chogwirira ntchito.Odzigudubuza awiri otsika amaikidwa pa bulaketi, ndipo bulaketi imasuntha m'njira yowongoka kuti ithandizire chogwirira ntchito.Mabakiteriya akutsogolo ndi akumbuyo amatha kusunthidwa kudzera pa screw screw, pomwe chogudubuza chapamwamba chimayikidwa pa ndodo yolondolera, yomwe imayenda motsatira dzenje.Thandizo likatha, ndodo yowongolera iyenera kukhazikitsidwa ndi zomangira.
Jack ali ndi zodzigudubuza ziwiri zokhala ndi mayendedwe ozungulira ngati malo ogwirira ntchito.Zodzigudubuza zimayikidwa pa jack, ndipo jack imayenda motsatira njira yothandizira ntchito.Ma jacks akutsogolo ndi akumbuyo amatha kusunthidwa nthawi imodzi kudzera pa zomangira zabwino ndi zoyipa, ndipo kulumikizana kwa ma roller awiriwo kumatha kusinthidwa kudzera pamanja owongolera kutsogolo.Pambuyo pothandizidwa, ma jacks onse ndi ndodo zowongolera ziyenera kukhazikitsidwa ndi zomangira.
(6）Kugwedera damper wosasunthika wa trepanning bar:
Chotsitsa chotsitsa cha vibration chimagwiritsidwa ntchito ngati chothandizira pa bar ya trepanning.Kwa mipiringidzo yowonda kwambiri, ndikofunikira kuwonjezera kuchuluka kwa zokhazikika moyenera.Kuyenda kwake panjira yolondolera bedi kumayendetsedwa ndi ngolo kapena kuthanso kuyendetsedwa ndi chida chamanja.Chida cha makina ichi chili ndi seti ya damper yokhazikika yokhazikika ya trepanning bar.
(7）Dongosolo lozizira:
Dongosolo loziziritsa lili kuseri kwa chida cha makina, makamaka chomwe chimakhala ndi thanki yamafuta, popopera, poyikira mafuta, ngolo yosungiramo chip, ndi poyambira mafuta.Ntchito ya choziziritsa kuzizira ndikuchotsa tchipisi tachitsulo.
