Kuwotchera kulikonse kolondola kumayamba osati ndi arc-koma ndi pamwamba pomwe sikuyenda. A kupanga jig table sizitsulo chabe pamiyendo. Ndiwothandizana naye chete pamsonkhano uliwonse womwe umabwerezedwanso: maziko omwe amamangirira kulolerana kuposa ma callouts anu a GD&T, amayamwa kugwedezeka asanasokoneze fillet, ndikusintha luso la opareshoni kuti likhale losasinthika.
Tawona mashopu ambiri akuthamangitsa kusokonekera kwa weld kuti tizindikire kuti chomwe chimayambitsa sikunali kutentha - kunali kuyenda pang'ono panthawi yothina. Mu projekiti ina ya zida zaulimi chaka chatha, cholakwa chamakasitomala chosungiramo masinthidwe chinali ± 0.8 mm kudutsa mabowo 12. Adakweza mfuti yawo ya MIG, adawonjezera gasi wotsuka, ngakhalenso zowotcherera pamagawo amphamvu. Kukonza? Wopangidwanso kupanga jig table okhala ndi ma pini a kinematic, zomangira zolimba zolimba, ndi zingwe zotchingira ziro-sewero. Kusintha komaliza kunatsikira ku ± 0.15 mm-mkati mwachidziwitso, popanda kukonzanso.
Chifukwa chiyani "Tebulo Yokha" Imalephera Pansi pa Zolemetsa Zapadziko Lonse
Tebulo la jig liyenera kuchita zinthu zitatu nthawi imodzi: kupeza, kukakamiza, ndikupulumuka. Si onse amene amatero.
Kupeza kumatanthauza kubwereza—osati kungogunda malo amodzi kamodzi, koma kuchita maulendo 500 kudutsa masinthidwe, kusintha kwa kutentha, ndi kuvala kwa zida. Timagwiritsa ntchito zitsulo zosapanga dzimbiri zopeza zisa zokhala ndi ± 0.01 mm flatness, osati mbale zamakina. Kukakamiza kumatanthauza kuteteza madigiri asanu ndi limodzi a ufulu-osati kukanikiza pansi, koma kukana kukweza, kupindika, ndi kukwawa kwapambuyo panthawi yowotcherera kutentha. Ichi ndichifukwa chake matebulo athu amaphatikiza njanji zowotcherera mu T-slot okhala ndi zida zotchingira zolemetsa-osati zida za bawuti. Kupulumuka kutanthauza kusunga ma weld pambuyo pa 3,000+ weld pass, osati kungopulumuka kuwala koyamba. Timatsitsimutsa mbale zonse zoyambira pambuyo pokonza ndikutsimikizira kukhazikika ndi kuseseratu kwa CMM musanayambe kugaya komaliza. Yendetsani pa chilichonse - ndipo mumalipira ndalama, kukonzanso, kapena kutumiza mochedwa. Tawona makasitomala m'malo $120k ma cell a robotic chifukwa tebulo lawo la jig linagwedezeka pansi pa njinga yamoto. Kukonza tebulo kumawononga 7% ya mtengo wa robot. Ndipo idaperekedwa m'masiku 11.
Zimene Amayinjiniya Amafunikira—Osati Zimene Timabuku Amalonjeza
Otsatsa ena amalemba "± 0.05 mm kulondola" popanda kunena zikhalidwe: kutentha kwa chipinda? Palibe zilowerere zotentha? Zotsitsa? Kulondola kwenikweni kwadziko lapansi kumadalira momwe tebulo limakhalira mukamawotchera nthawi ya 4 koloko, ndi kutentha kozungulira 15 ° C usiku wonse.
Chifukwa chake timapanga chilichonse kupanga jig table kwa kupirira ntchito:
Zida zoyambira: Chitsulo cha ASTM A572 Giredi 50—osati chitsulo chocheperako—chotenthedwa mpaka kulimba kwa 220–250 HB, kenako kutsetsereka mpaka 0.005 mm kupitirira 2 m². Makina okwera: Kuphatikizika kwa 10-mm T-slot njanji zokhala ndi zomangira zolimba (62 HRC), zoyesedwa mpaka 12,000 N kukakamiza kwa njanji pagawo lililonse. Kuwongolera kutentha: Zosankha zoyambira zoziziritsa m'madzi zopangira ntchito zapamwamba-zoyesedwa mpaka 200 welds / ola popanda kupindika. Modularity: Malo olumikizirana okhazikika amalola ogwiritsa ntchito kusintha malo omwe ali, kuwonjezera zikhomo za mpweya, kapena kuphatikizira masomphenya olunjika - zonsezi popanda kuboola mabowo atsopano. Sitigulitsa "matebulo". Timapereka ma calibrated positioning systems. Chigawo chilichonse chimatumiza lipoti lathunthu la CMM losonyeza kuphwatalala, kufanana, ndi mayendedwe a njanji kupita ku njanji—kutsatiridwa ndi miyezo ya NIST.
Palibe Zochepa. Palibe Guesswork. Palibe Compromise on Traceability
Magulu ang'onoang'ono ang'onoang'ono asatanthauze zida za gawo lachiwiri. Wogulitsa magalimoto m'modzi waku Europe wa Tier-1 amafunikira ma jig 14 - kuti atsimikizire zachitsanzo pa bulaketi yatsopano ya batri ya EV. Wogulitsa wawo wam'mbuyomu adatchula masabata 12 ndipo amafunikira mayunitsi 50 osachepera. Tinapereka matebulo 14 omwe anawunikiridwa mokwanira, ovomerezeka ndi CAD m'masiku 16. Chigawo chilichonse chinali ndi ndemanga za DFM, malingaliro a katsatidwe ka weld, ndi ma satifiketi azinthu za EN 10131 DC04 zitsulo zozizira.
Izi zimagwira ntchito chifukwa kuthekera kwathu kumakhala koyimirira-osati kusanjika:
Kapangidwe: Akatswiri a m'nyumba a GD&T amawunikanso mtundu wanu wa 3D ndi zoopsa zosokoneza mbendera musanatchule. Mangani: Kudula kwa plasma ya CNC, kuwotcherera kwa maloboti, ndikumaliza ndi manja -zonse zili pansi pa denga limodzi lovomerezeka la ISO 9001. Tsimikizirani: Gome lililonse limayesedwa ndi zida zopangira ndi zomangira zenizeni - osati ma caliper okha. Thandizo: Kutumiza, timasunga zidziwitso zanu za CMM, mapu a weld, ndi kusanthula kwapang'onopang'ono kuti tiwunikenso mtsogolo. Palibe kutumiza kunja. Palibe ma handoffs. Ayi "tidzayang'ana pakupanga." Gulu limodzi lokha-kuchokera ku mawu mpaka kutumidwa.
Gawo Lanu Lotsatira Si Mawu Enanso. Ndi Protocol Yotsimikizira.
Musanasiyine pa ina kupanga jig table, funsani: Kodi zimabwera ndi cholembera chokhazikika cha kutentha? Kodi mungatsimikizire kusalala kwake pansi pa katundu-osati popuma? Kodi njira yopezera malo idapangidwira kusintha kwanthawi yoyipa kwambiri - kapena geometry yabwino?
Botou Haijun Metal Products Co., Ltd. imamanga matebulo a jig pomwe zolinga zauinjiniya zimakumana ndi zenizeni zapashopu. Tatumiza makina opitilira 870 olondola kwambiri kuyambira 2019-kwa makasitomala aku Germany omanga makina opangira makina opangira mphepo, kumakampani aku US ag-tech omwe amasonkhanitsa mafelemu opopera odziyimira pawokha, kwa othandizira a EMS aku Southeast Asia omwe amasonkhanitsa chassis yamaloboti azachipatala. Onse amagawana chofunikira chimodzi: kusalolera ziro pakuyenda kwapadziko.
Ngati msonkhano wanu wotsatira ukufuna kubwerezabwereza-osati chiyembekezo-yambani ndi choonadi chapamwamba. Yambani ndi a kupanga jig table linapangidwa kuti lizigwira ntchito, zowotcherera pambuyo pa kuwotcherera, chaka ndi chaka.
