Amathebula ezinto zokushisela aguqula indlela abenzi bokwenza izinto ababamba ngayo, bathole, futhi baphinde izingxenye—kungasekho ukucisha ngeso, akusasebenzi kabusha kusuka ekukhukhuleni. Sibone izitolo zinciphisa isikhathi sokusetha ngo-65% ngemva kokusuka ku-jig yangokwezifiso ukuya kwe-modular welding fixture table izinhlelo. Ikhasimende elilodwa e-Changzhou lishicekele ozimele be-chassis abafanayo iminyaka emithathu lisebenzisa ipuleti lesisekelo elilodwa kanye namathuluzi ashintshashintshayo—ukuchezuka kwe-zero dimensional kumayunithi angu-12,000.
Kungani ukuphindaphinda kuqala etafuleni-hhayi kumshiseli
Amaphutha amaningi wokushisela aqala ngaphambi kokuthi i-arc ishaye. Ingxenye ishintsha ngo-0.3 mm ngesikhathi sokubopha. Umhlathi we-vise ugqoka ngokungalingani. Indawo ephansi ilahlekelwa ukucaba ngemva kwemijikelezo emihlanu yokushisa. Lawa akuwona "amaphutha omqhubi." Ziwukwehluleka kwesistimu-futhi zihlanganiswa nawo wonke amalunga.
A iqiniso welding fixture table ixazulula lokhu kusisekelo. Akulona nje ipuleti lensimbi elinezimbobo. Iwuhlelo lokuxhumanisa olugxiliswe ekubekezeleleni kwe-ISO 2768-mK, enezikhala ze-T ezihlukaniswe ngezikhathi eziqondile ezingu-50-mm, izindawo eziphezulu eziqinile (HRC 58–62), kanye namandla okuthwala aqinisekisiwe nge-DIN 53404 ngayinye. Lokho kusho ukuthi ithebula elilinganiselwe ngo-1,200 kg libamba u-3,600 kg ngaphandle kokuchezuka okulinganisekayo.
Ukwehluleka komhlaba wangempela kwenzeka lapho abasebenzisi beziba ukuqina okukhulayo. Ukubophela itafula lokulungisa kuhlaka lwensimbi oluncane oluyi-6-mm? Lindela ukwehla okungu-0.18 mm ngaphansi kokulayisha okungu-800 kg. Ikhweze kusisekelo sensimbi esinesakhiwo esingu-25-mm esinamabhawodi amane ahange i-M16 athotshiswe ku-190 N·m? Ukuchezuka kwehla ku-0.02 mm. Ithebula aliqambi amanga-isakhiwo sokusekela siyakwenza.
I-Modular vs. fixed: Yikuphi okuletha i-ROI ezinsukwini ezingu-90?
Ezinye ziphikisana nezinhlelo ezakhelwe ngokwezifiso zehlula amatafula e-modular ngokunemba. Kodwa silandelele izitolo zemisebenzi eziyi-17 eziphakathi nendawo ezinyangeni eziyi-18. Labo abasebenzisa ama-jig alungisiwe benza isilinganiso esingu-$4,200 ngesikhathi sokuphumula sonyaka esiteshini ngasinye—ikakhulukazi kusukela ekubambezelekeni kokuklama kabusha kanye nemfuhlumfuhlu yesitoreji. I-modular welding fixture table abasebenzisi bachithe u-$1,100 ekubuyekezweni kwamathuluzi minyaka yonke futhi bathole amahora angu-11/ngesonto ohlelweni nesikhathi sesakhiwo.
Umehluko usekuguquguqukeni. Isistimu ye-modular isebenzisa izingxenye ezijwayelekile: ama-profile rails (20 × 20 mm, 30 × 30 mm, noma 40 × 40 mm ama-aluminium extrusions), izinsimbi zokuvala ezinokuphindaphinda okungu-±0.02 mm, nezitholi ezishintsha ngokushesha ezinamaphini ensimbi aqinile (Ø6 mm, Ø8 mm, Ø10 mm). Wakha into entsha ngaphansi kwemizuzu engama-90—hhayi izinsuku ezintathu.
Nakhu okusebenzayo-nokuthi yini engasebenzi:
- Iyasebenza: Kusetshenziswa izikhonkwane zedowel ezingu-Ø10 mm endaweni eyinhloko; ukubhanqa amantongomane e-T-slot anezikulufu ze-cap ezinephrofayili ephansi (M6 × 12 mm) ukuze kugwenywe ukuphazamiseka kwemizila yethoshi yerobhothi
- Iyahluleka: Ukupakisha izendlalelo ezintathu zamapuleti e-adaptha ngaphandle kokulinganisa kabusha idatha ye-axis ye-Z; usebenzisa izinsimbi ezinezingqimba zepulasitiki kunsimbi egoqelwe eshisayo engaphezu kuka-120°C
- Kushaywe indiva: Ukuqhubeka kokugawula—zonke izinsimbi kufanele zigcine ≤0.1 Ω ukumelana nendawo yetafula. Sikala lokhu nge-Fluke 1625-2 ngaphambi kokuthunywa
I-Botou Haijun Metal Products Co., Ltd. iklama amatafula ayo azungeze lezi zimo ezingokoqobo. Kusukela ngo-2010, onjiniyela bethu bafake amayunithi angaphezu kuka-2,300 kubo bonke abahlinzeki bezimoto abangaphansi kwesigaba sezimoto, abenzi bempahla yezolimo, namadepho okukhanda izimoto zikaloliwe—konke eDolobheni laseBotou, eSifundazweni saseHebei, lapho izinga lokushisa lishintsha ukusuka ku-−15°C ukuya ku-42°C minyaka yonke. Ukuzinza kwe-thermal akuyona inketho. Yakhelwe esisekelweni sensimbi esidambisa ukucindezelwa kanye ne-slot geometry enxeshezelwe.
Ukufaka akuyona i-plug-and-play-futhi yilokho iphuzu
Udinga ukhonkolo osezingeni, hhayi phansi esitolo esine-epoxy-dusted. Ubuncane be-slab ukujiya: 150 mm. Isikhala sebha: ≤200 mm phakathi nendawo-kuya-maphakathi. Ukujula kwebhawodi yehange: ≥180 mm kukhonkolo olashiwe (hhayi ukuthela okuluhlaza). Yeqa noma yisiphi isinyathelo, futhi ukubekezelela kwakho okungu-0.05 mm kuba ngu-0.4 mm phakathi nezinyanga eziyisithupha.
Sidinga ukuqondanisa kwe-laser phakathi nokufakwa kokugcina—sisebenzisa i-Leica Geosystems LS15 rotary laser, hhayi ileveli yomoya. Kungani? Ngoba amandla adonsela phansi awanandaba nebhendi yakho yokubekezelelana. Ukutshekisa okungu-0.1° kuthebula elingu-2,000 mm kudala ukuhluka kobude obungu-3.5 mm ekugcineni okude. Lokho kwanele ukumisa kabi i-robotic seam tracker.
Amandla kanye nendaba yesisekelo nayo. Amathebula ezinto zokushisela kufanele ahlanganiswe ohlelweni lwe-grounding olufanayo nomthombo wamandla. Azikho izinduku ezihlukene. Akukho okungathathi hlangothi okwabiwe. Indlela eyodwa eqhubekayo—iqinisekiswe nge-megohmmeter ku-500 V DC. Sibhala konke ukufundwa kokuphikisana embikweni wokugunyazwa. Amakhasimende eqa lokhu abona ukugqokwa kwangaphambi kwesikhathi kumagayidi alayini kanye nokuma kwe-CNC okuyiphutha.
I-Botou Haijun inikeza ukwesekwa okugcwele kokufakwa—hhayi nje amamanuwali. Ochwepheshe bethu baphatha izingalo eziphathwayo ze-CMM ukuze baqinisekise ukucaba ngemva kokufakwa. Ukubekezelela ukucaba kungu-≤0.08 mm ngaphezu kwanoma iyiphi indawo engu-1,000 × 1,000 mm. Uma ihluleka, silungisa ama-shim noma siphinde sibhoboze amahange—endaweni.
Ukunemba akusona isici. Yisisekelo.
A welding fixture table ayenzi ama-welds aqine. Kubenza babikezeleke. Iguqula ukuhluka kobukhulu kube okuguquguqukayo okulawulwayo—hhayi ilotho. Izitolo ezikuthatha njengengqalasizinda-hhayi okokusebenza-bona amazinga e-scrap ehla esuka ku-4.7% aya ku-0.9% ngaphansi kwezinyanga ezine. Bayeka ukubuza ukuthi "Sikutholile kahle?" bese uqala ukubuza ukuthi “Singakala ngokushesha kangakanani?”
Lolo shintsho luqala ngokukhethwa kwezinto ezibonakalayo (insimbi encibilikisiwe engu-EN-GJL-250, hhayi insimbi eshiselwe), iqhubeka ngomshini webanga le-metrology (izikhala ezigaywe ze-CNC ezibanjwe ku-±0.015 mm), futhi ziphethe ngokuqinisekisa komhlaba wangempela—hhayi imininingwane yelebhu. I-Botou Haijun Metal Products Co., Ltd. yakhela phansi esitolo, hhayi indawo yombukiso. Ithebula ngalinye lihamba ngesitifiketi sokulinganisa esilandelekayo, imininingwane egcwele yetorque, kanye nedatha yokunwetshwa kwezinga lokushisa yendawo yakho yesimo sezulu.
Ikusasa ngelabakhiqizi abashisela kanye—futhi bakulungise. Hhayi labo abashiselayo, abakalayo, abagayayo, abashisela kabusha, nabanethemba. Ithebula lakho elilandelayo lokulungisa akufanele libe nezingxenye. Kufanele iqinisekise imiphumela.
