Konke ukusilela komdlalo we-BIW kuqala ngendlela efanayo-hayi ngokuntlitheka, kodwa ngolungelelwaniso olufihlakeleyo ngexesha lokuqala le-takt. Siyibonile kumazwekazi amathathu: i-0.15 mm ye-datum shift kwindawo yepaneli yecala ibangela ukupakishwa kokunyamezela kwizikhululo ezintandathu; i-welded base plate warps emva kweeyure ze-48 zokusebenza okuqhubekayo; i-pneumatic clamp ilahlekelwa ukubamba amandla kwi-32 ° C ambient-ngaphezu nje kobushushu beshifti yehlobo e-Chennai okanye eMonterrey.
Kutheni i-BIW Fixture Design iyiNjini ethuleyo yokuSebenza ngokuFanelekileyo kweeMoto
Isixhobo se-BIW ayisiyiyo nje intsimbi yokubamba isinyithi. Luguqulelo olubonakalayo lwe-GD&T nenjongo kwinyani ephindaphindwayo ye-kinematic. E-Botou Haijun Metal Products Co., Ltd., siye sakha kwaye saqinisekisa ngaphezulu kwe-1,270 ye-BIW fixtures ukususela ngo-2016-nganye ivavanywa phantsi kwemithwalo yokwenyani yemveliso, imijikelezo ye-thermal, kunye namaxesha okugcina. Idatha yethu ibonisa ukuba i-68% yokuyeka umgca ongacwangciswanga kwiivenkile zomzimba ze-Tier-1 zibuyela emva kwiingcambu ezinxulumene ne-fixture-related root: i-locator igugile ngaphaya kwe-0.08 mm, ukuqina kwesiseko esingaphantsi kwe-2.3 × 10⁵ N / mm, okanye ukubola kwamandla okubamba ngaphezu kwe-12% ngaphezu kwemijikelo ye-10,000.
Olona celomngeni? Ulungiso kufuneka lwanelise iimeko ezine ezingaxoxiswanga ngaxeshanye: uzinzo kinematic (akukho mqobo), ukungathathi hlangothi kwe-thermal (ΔL ≤ 0.03 mm ukusuka kwi-20-40 ° C), ukuqina kwenkonzo (≥ 500,000 imijikelo ngaphandle kohlengahlengiso), kunye ergonomics yomntu (i-clamp actuation force ≤ 22 N, ixesha lokujikeleza ≤ 4.2 imizuzwana). Ukulalanisa nayiphi na enye-kunye nokusebenza kakuhle kuyawa.
Izigqibo eziThathu zoYilo lweLizwe lokwenyani Ezenza okanye Ezophula i-BIW Fixture Performance
1. Ukukhethwa kwezinto eziphathekayo akukhona malunga namandla-kumalunga nememori ye-dimensional. Siyekile ukusebenzisa i-A36 yensimbi yeeplate zesiseko kwi-2020. I-coefficient yayo yokwandiswa kwe-thermal (12.0 × 10⁻⁶ / ° C) ibangele i-drift enokulinganisa ngexesha lokunyuka kweqondo lokushisa eliphakathi. Namhlanje, sicacisa i-ASTM A572 yeBanga le-50 kunye nokunciphisa uxinzelelo lwe-post-machining-kwaye kuphela xa idibene nomjikelo wokuguga weeyure ezingama-72. Kwiindawo ezichanekileyo ezichanekileyo, sisebenzisa i-17-4 PH insimbi engenasici, iphathwa ukushisa ukuya kwi-H900 (485 HB), ukufezekisa ukuzinza kobunzima ngaphakathi kwe-± 1.3 HRc kwiminyaka eyi-3 yokusetyenziswa kwentsimi.
2. Isicwangciso sokubambelela simisela inxalenye yokukhululwa-kungekhona nje ukubamba amandla. Izithinteli zomoya zisilela xa umoya ocinezelweyo une>0.5 ppm yeoli okanye indawo yombethe ingaphezu kwe-3°C. Isisombululo sethu: iindlela ezimbini zokubamba. Izibonda eziphambili zisebenzisa iisilinda ze-ISO 15552 ezinezinzwa zendawo ezidibeneyo; i-second "soft-touch-touch" ii-clamps zisebenzisa i-spring-loaded urethane pads (i-Shore A 70) ezixinzelela i-1.2 mm phambi koqhagamshelwano-ukuphelisa ukubola kwiindawo ze-Class-A. Ubomi bomjikelo butsiba ukusuka kwi-180,000 ukuya kwi-620,000 yentshukumo.
3. Isakhiwo seDatum kufuneka sibonise ukulandelelana kwendibano-kungekhona imodeli yeCAD. I-OEM enye yaseYurophu igxininise ekufumaneni i-3-2-1 kwisikhululo ngasinye. Sakha yona. Emva koko wabukela inxalenye yayo isiya isiba mandundu emva kweSikhululo sesi-4. Oyena nobangela? Ulandelelwano lwabo lwe-weld lwe-weld lulayishe inxalenye ngokulinganayo, ibangela ukuguqulwa kwe-elastic enokuthi ukulungiswa kungenakuhlawulela. Sayila ngokutsha ngokulandelelana kwedatum transfer: Isikhululo 1 sitshixa iiflange zomgangatho wepan; Isitishi sesi-3 songeza inkxaso ye-sill yecala *kuphela emva kokuba* i-rocker panel welding; Isitishi sesi-6 sazisa iilokhi zikaloliwe eziphahleni—kungekhona ngaphambili. Isivuno sokuphumelela kokuqala sinyuke ukusuka kuma-71% ukuya kuma-99.4%.
Yintoni uninzi lweeNjineli ezingayijongiyo (kunye nendlela yokuyilungisa)
Abanye baphikisa ngelithi uyilo lwezixhobo zenziwa ngoomatshini kuphela—ukubala amandla kwaye ukhethe imathiriyeli. Kodwa idatha yethu yentsimi iyayiphikisa loo nto. Kwi-41% yemidlalo ekhatyiweyo, isiphene besingalungelelananga. Ibingumntu: abaqhubi begqitha izitshixo zokhuseleko ngenxa yokuba ii-clamp actuator zifuna i-32 N yonyanzeliso, okanye amagcisa atsiba ukulinganisa kuba ufikelelo lwe-CMM lufuna ukuchithwa ngokupheleleyo.
Silungisa oku ngoqeqesho loyilo oluzinzisiweyo:
Ukunyanzelela ukwenza imephu: Yonke into yokubamba, i-lever, kunye ne-pedal ifumana ukuqinisekiswa kwe-ergonomic-ubuninzi be-actuation force efakwe kwi-18 N, umgama wokuhamba uqiniswe kwi-42-48 mm. Ukugcinwa kwejometri yokuqala: Zonke izibophelelo zihlala ngaphakathi kwe-120 ° arc yokufikelela kumqhubi; iithagethi zokulinganisa zenziwa ngoomatshini ngokuthe ngqo kwimizimba-ayidityaniswa njengeepleyiti zebholiti Ukuqhawulwa kwe-Thermal: Iipleyiti ezisisiseko zikhwela kwi-elastomeric isolators (i-durometer 55 Shore A) kunye ne-0.8 mm static deflection-ithintela ukuhanjiswa kwe-vibration ye-shop-floor ngaphantsi kwe-15 Hz Oku akuyothiyori. Ucango lwangaphakathi lwamva nje olufakwe ngaphakathi lwenkqubo ye-EV yaseMntla Melika iqhube i-14,200 imijikelezo engaphazamisekiyo ngaphambi kokulungiswa kokuqala-ukugqithisa i-OEM ekujoliswe kuyo ngama-310%.
Ukusuka kuMzobo ukuya kwi-Deployment: I-Haijun Validation Protocol
Asithumeli izixhobo-sithumela inkqubo eqinisekisiweyo yenkqubo. Wonke umzobo we-BIW uphantsi kwezigaba ezine zokuqinisekisa:
Ukulinganisa okudityanisiweyo kweDFM: Umzimba ogcweleyo we-FEA (ANSYS Mechanical) imodeli yokuqhuba i-thermal, i-clamping distortion, kunye nokudinwa komjikelo wezigidi ezili-10-usebenzisa idatha yovavanyo lwezinto ezivela kwilebhu yethu yangaphakathi. Uvavanyo lweprototype yomzimba: Uvavanyo lobomi olukhawulezileyo lweeyure ezingama-72 phantsi koxinzelelo lokwenyani lwe-pneumatic, ukuhamba ngebhayisikile kweqondo lobushushu (20–45°C), kunye nokulayishwa kwerobhothi okufanisiweyo (± 15% ukwahluka kwamandla) Ivenkile-kumgangatho owomileyo: Ifakwe kwindawo yomthengi kwii-3 shifts-ukulinganisa ukuphindaphinda kwendawo (Cpk ≥ 1.67), ixesha lokujikeleza kwe-clamp (± 0.15 s), kunye namanqaku empendulo yomqhubi Amaxwebhu anokulandeleka: Ingxelo yokugqibela ibandakanya i-CMM yokwaleka kwescan, ukufundwa kwegeji yoxinzelelo, kunye netemplates yelog yolondolozo-zonke zinikezelwe kwiiyure ezingama-72 zokusayina I-Botou Haijun Metal Products Co., Ltd. isebenza ukusuka kwisiXeko saseBotou-intliziyo ye-ecosystem yaseChina esebenza ngokubanda-apho ukuchaneka kungenakuzikhethela. Yisiseko. Xa ufuna i ukulungiswa kwe-biw leyo ibambe inyani kuwo wonke amaxesha onyaka, utshintsho, kunye notshintsho lomthengisi, qala ngememori ephakathi-hayi nje ubunzima bentsimbi.
