Kupanga a weld test fixture sizokhudza kulumikiza zigawo pamodzi ndikuyembekeza zotsatira zofanana. Ndi za kukulitsa cholinga chanu cha uinjiniya-pomwe malo aliwonse, pini, ndi mphamvu yotchinga imamasulira mwachindunji kumtundu wobwerezabwereza, kukhazikika kwa mawonekedwe, komanso chidaliro choyendera. Ku Botou Haijun Metal Products Co., Ltd., tapanga zopitilira 270 ma weld test fixtures kwa ogulitsa magalimoto a Tier-1, OEM zida zaulimi, ndi zophatikiza zamagetsi zamagetsi. Mulimonsemo, kulephera kuthana ndi zoyambira zoyambira zidapangitsa chimodzi kapena zingapo mwazotsatira izi: ma weld seams olakwika, kupita zabodza / kulephera kuwerengera pakutsimikizira, kapena kukonzanso kokwera mtengo pambuyo poyambitsa kupanga.
Nangula Mbali—Osati Kungoigwira
Magulu ambiri amayamba ndi njira yochepetsera - koma ndizobwerera m'mbuyo. Choyamba, fotokozerani dongosolo la datum pogwiritsa ntchito mawonekedwe a gawolo: flange yokwera, bwana wokweretsa, kapena ndondomeko yovuta kwambiri yomwe imasonyeza momwe chigawocho chikugwirizana ndi msonkhano womaliza. Timagwiritsa ntchito mfundo zitatu pazigawo zoyambira, osati zinayi - chifukwa mfundo zinayi zimapangitsa kupotoza kwazitsulo zazitsulo zopyapyala. Pa bulaketi wamba wopangidwa kuchokera ku chitsulo chozizira cha 2.0 mm, timatchula zikhomo zolimba zolimba zokhala ndi ± 0.005 mm m'mimba mwake, zofikira pazitsamba zokhala pansi pazitsulo zopumira za aluminiyamu 6061-T6. Chifukwa chiyani aluminiyamu? Imapangidwa mwaukhondo, imachepetsa kugwedezeka pa kuwotcherera kwa robotic, ndipo imalemera 60% kuchepera kuposa chitsulo chogwirira ntchito. Timapewa zitsulo zachitsulo pokhapokha ngati kutenthedwa kukufunika kuti tiyesedwe mozungulira kwambiri - kuphulika kwake kumaika pangozi ming'alu yaing'ono pafupi ndi mabowo oponyedwa pambuyo pa ma torque mobwerezabwereza.
Lamulirani Kukula Kwamafuta—Arc Isanamenyedwe
Kuwotcherera kumapanga kutentha komweko mpaka 1500 ° C. Mphamvu imeneyo siitha—imasamuka. Mosasunthika, imakhota malo olowera, imasuntha malo a pini mpaka 0.08 mm, ndikulepheretsa muyeso uliwonse wotsatira. Kukonzekera kwathu: strategic copper alloy inserts at weld proximity zones. Kutentha kwa Copper (401 W/m·K) kumakokera kutentha kuwirikiza kasanu kuposa aluminiyamu. Timayika midadada yamkuwa ya OFHC molunjika pansi pa zolumikizira zowotcherera, zomangika ndi zomangira za M4 kapu komanso otalikirana ndi kapangidwe kake pogwiritsa ntchito shimu 0.5 mm PTFE. Izi sizongoyerekeza - tidayezera 32% kutsika kwamafuta otsika pamayeso opirira maulendo 120 motsutsana ndi zida zonse za aluminiyamu. Bonasi: chikhalidwe chopanda maginito cha mkuwa chimalepheretsa kusokoneza kwa arc panthawi yovomerezeka ya TIG.
Mangani Kuti Mutsimikizire—Osati Kungogwiritsa Ntchito
A weld test fixture iyenera kutsimikizira kulondola kwake. Kapangidwe kalikonse kamakhala ndi zotsimikizira zomangidwira: ma flatreferensi olondola (Ra ≤ 0.4 µm), malo ofikirako ndi CMM pamatchulidwe ofunikira a GD&T, ndi mipiringidzo yochotsamo yotsatiridwa ndi miyezo ya NIST. Makasitomala m'modzi adaumirira kuti "pasakhale mabowo owonjezera" - chifukwa chake tidapanga ma Ø6.35 mm ozungulira kuti akhale pamalo olowera m'malo mwake. Izi zimavomereza masitayelo wamba a CMM opanda ma adapter ndikupulumuka maulendo oyendera 10,000+. Timaphatikizanso mapanelo olowa mwachangu pazida zamkati, kulola ogwiritsa ntchito kutsimikizira kutalika kwa malo mkati mwa masekondi 90—osati mphindi 20 kuchotsa gulu lonse. Ngati simungathe kuyeza kukhulupirika kwa chipangizocho mwachangu kuposa momwe mumayendera, mukudalira mwayi, osati deta.
Gwirizanitsani Kukhazikika Kwadongosolo ndi Njira Yanu-Osati Bajeti Yanu
Kukhazikika sikukhudza makulidwe - ndi nthawi yogawa inertia. Chitsulo chachitsulo cha 30 mm chikuwoneka cholimba mpaka mutawonjezera mkono wa cantilever wa 120 mm kuti muwongolere tochi ya robotic. Kenako kupatuka kumagunda 0.12 mm pansi pa 45 N ya mphamvu yowotcherera. Yankho lathu: zomangamanga zosakanizidwa. Main base = 25 mm wandiweyani 7075-T6 aluminiyamu (mphamvu-kulemera kwambiri). njanji zovuta locator = zomangira zitsulo zosapanga dzimbiri 304 n'kupanga (zokolola mphamvu 505 MPa). Mzere wa bond umagwiritsa ntchito epoxy-grade-grade epoxy yokhala ndi 0.05 mm-controlled gap-yotsimikiziridwa ndi ultrasonic pulse-echo scanning. Izi zimapereka 2.3 × kuuma kwamphamvu kwambiri kuposa aluminiyamu ya monolithic pa 18% yotsika kulemera. Timatsimikizira kamangidwe kalikonse ndi FEA modal kusanthula kolunjika koyamba kwachilengedwe> 120 Hz—kuposa ma loboti omwe amawotchera wamba. Palibe phokoso. Palibe kuyenda. Palibe zifukwa.
Aliyense weld test fixture timapereka zombo zokhala ndi phukusi lathunthu la metrology: lipoti la CMM lomwe limamangidwa, ma curve otenthetsera, ndi kafukufuku wobwerezabwereza pa oyendetsa atatu ndi masinthidwe awiri. Chifukwa kulondola sizomwe zimanenedwa - ndizomwe zimapulumuka kugwiritsidwa ntchito kwenikweni. Botou Haijun Metal Products Co., Ltd. imamanga akatswiri opanga ma injiniya kukhulupilira pamene ndalama zowonongeka zimadutsa $1,200 pagulu lililonse loyipa la weld. Ngati panopa weld test fixture imafuna kukonzanso tsiku ndi tsiku kapena kulephera kuwunika kwa GD&T pambuyo pa mizungu 500, cholakwikacho sichili m'dongosolo lanu - chili pamaziko. Yambirani pamenepo.
