I-laser welding fixture design ihlukanisa ukukhiqizwa okuthembekile kusuka ekusebenzeni kabusha okubizayo. Sibone amaklayenti echitha amasonto elungisa i-weld splatter, ukungaqondani kahle, noma ukuhlanekezelwa kwengxenye—ukuze alandele umsuka wesizathu emuva kokuthi i-weld splatter ingasebenzi kahle. Ukunemba akwengezwa ekucutshungulweni kwangemuva; ikhiyelwe *ngaphambi* komlilo we-laser. E-Botou Haijun Metal Products Co., Ltd., sakha izinto zokushisela nge-laser hhayi njengezibambi ezingenzi lutho, kodwa njengabahlanganyeli abakhuthele ekuphindaphindeni, ukuphatha okushisayo, nokuthembeka kwejometri.
Kungani Ukulungiswa Okujwayelekile Kwehluleka Ngaphansi Kwezimo Ze-Laser
Amandla okubamba umakhenikha ewodwa awakuqinisekisi ukuzinza ngesikhathi sokuchayeka kwe-laser engu-1–10 kW. Umehluko wokunwebeka okushisayo phakathi kwesisekelo sezinto eziyisisekelo kanye nocezu lokusebenza kungashintsha ingxenye ngo-0.08 mm phakathi kwamasekhondi angu-3—okwanele ukuvula igebe elingu-0.2 mm endaweni ehlangene yokushisela. Silinganise lokhu ngokuphindaphindiwe sisebenzisa ama-thermocouples ashumekiwe kanye nokulandelela kwe-CMM enesivinini esikhulu kumaassemblies ensimbi engagqwali. Izinto eziningi ezingaphandle kweshelufu zisebenzisa i-aluminium engu-6061-T6 ukuze ibe lula—kodwa i-coefficient yayo yokwandisa okushisayo (23.6 µm/m·°C) icishe iphindwe kabili kune-304 stainless (17.3 µm/m·°C). Lokho kungafani kubangela ukunyakaza okuncane, ukugxila kwe-beam okungahambisani, kanye ne-porosity.
Ukulungiswa nakho kuyahluleka uma kuziba izithiyo eziqondene ne-laser: ukufinyelela komugqa wokubona kwe-collimated optics, ukucaciswa kokugeleza kwegesi yokuhlanza umlomo wombhobho, kanye nokwelashwa kwendawo engabonisi ukukhanya. Iphinikhodi epholishiwe ye-stainless 316L ingase ibukeke njengeprimiyamu—kodwa ibonisa amandla angu-65% we-1070 nm we-beam ebuyela kokubonayo. Sishintshele kumaphini we-Inconel 718 we-matte-finish ngemva kokushintshwa kwamalensi amabili ngesonto elilodwa.
Izimiso Zomklamo Ezine Ezingaxoxiswana Sizisebenzisayo
Zonke izinto zokushisela nge-laser esizilethayo zilandela le mithetho eqinisekiswe yinkundla:
I-Thermal Decouupling: Izisekelo zokulungisa zisebenzisa izinto ezisebenza kancane njenge-G10 fiberglass noma i-PEEK egcwele i-ceramic lapho ukudlulisa ukushisa okuqondile kufanele kuncishiswe. Izindawo ezibucayi zigibela kumapuleti angaphansi ensimbi engenasici angawodwa anezindawo ezishisayo. I-Dynamic Clamping: Ama-actuator kagesi womoya noma we-servo-electric asebenzisa i-clamping pressure engu-15–25 N/mm²—akalwa ngesikhathi sangempela—hhayi amandla asentwasahlobo asethiwe. I-over-clamping ikhubaza kubakaki begeji elincane; i-under-clamping ivumela i-weld ripple ebangelwa ukudlidliza. Ubuqotho bobuso bereferensi: Zonke izindawo ze-datum ziphansi ku-Ra ≤ 0.4 µm futhi ziqinisekiswa nge-optical flat interferometry. Senqaba noma iyiphi indawo enenani elingu->0.005 mm lokufunda inkomba ku-100 mm—ngoba iphutha elingu-0.003 mm endaweni liba ngu-0.012 mm lapho kuthungwa i-weld engu-400 mm. I-Modular Reconfigurability: Awekho amaphini ashiselwe. Sonke isitholi sisebenzisa okufakwe ngochungechunge lwe-M4–M8 okunamaphinikhodi edowel ensimbi aqinile (HRC 60–62), okuvumela ukusetshenzwa kabusha okugcwele ngaphansi kwamaminithi angu-90 ngaphandle kokulungiswa kabusha. Ungakhetha Nini Okwezifiso vs. I-Modular Laser Welding Fixtures
Abanye onjiniyela bacabanga ukuthi amakhithi e-modular asindisa isikhathi. Kodwa silandelele amaphrojekthi angu-17 lapho amasistimu “alingana ngokushesha” adinga imizuliswano emithathu yokucwebezela, amahora amahlanu okuhlelwa kabusha kwendlela ye-laser, kanye nokwehla kwamandla e-weld ngo-12–18%. I-modular isebenza kuphela uma ingxenye yejiyomethri ihlala ifana kuzo zonke izinhlobo ezingu-≥10—futhi nalapho, ukukhukhuleka okushisayo kunqwabelana ngokushesha kunangemiklamo eyakhelwe inhloso.
Ukuthuthukiswa kwezinto zokushisela i-laser kubuyisela emuva ngaphansi kwamahora okukhiqiza angu-420 ezingxenyeni ezinezithungo zokushisela ezingu-≥3 noma ukubekezelela okuqina kuno-±0.1 mm. Isikhathi sethu esijwayelekile sokuhola? Izinsuku zokusebenza eziyi-12 kusukela emdwebeni ogunyaziwe we-GD&T kuya embikweni wokuhlolwa kwesihloko sokuqala—okuhlanganisa nokuqinisekiswa kwe-CMM yazo zonke izici zedatha ngokumelene ne-ISO 1101.
Asicaphuni ama-fixtures ngawodwa. Sonke isicelo sivusa isibuyekezo se-DFM: Ingabe ukujoyina kuyafinyeleleka ku-15° ubuncane be-engeli? Ingabe ukuqina kwengxenye kusekela ukugoqa ngaphandle kokululama okunwebekayo? Ingabe izindawo ze-weld seam azinawo amaphakethe egesi avaleleke? Simaka izinkinga ngaphambi kokusika insimbi—ngoba ukuzilungisa kamuva kubiza u-7× ngaphezulu.
Amamethrikhi Okusebenza Omhlaba Wangempela Ongawaqinisekisa
Izakhiwo zethu zihlala ziletha imiphumela elinganisekayo—hhayi izimangalo zokumaketha:
Ukuphindaphinda kwesikhundla se-Weld: ±0.03 mm ngaphezu kwemijikelezo engu-1,000 (kuqinisekiswe nge-laser tracker) Ukushintshashintsha kokulungisa kuya kokulungisa: ≤0.05 mm ukuchezuka okukhulu kumayunithi ama-5 akhelwe ekuphrinteni okufanayo Isikhathi esimaphakathi phakathi kokulungiswa: 14,200 welds (kusekelwe idatha yangaphakathi 2023 kuzo zonke 47 izinhlelo zabakaki bezimoto) Ukugcinwa kokuqedwa kobuso: Ra ≤ 0.6 µm ezindaweni ezibalulekile ngemva kweminyaka engu-2 yokusetshenziswa nsuku zonke Zonke izinto ezilungiswayo zithunyelwa ngezitifiketi zokulinganisa ezilandeleka ku-NIM China, okuhlanganisa ama-coefficients anwebekayo ashisayo ngendawo ngayinye yezinto kanye namamephu wamandla okubamba akhiqizwe ekuhlolweni kwe-strain-gauge.
Ukusebenza kwe-laser welding akuyona ithiyori—kukalwa ngama-microns, ama-millisecond, namazinga esivuno. I-Botou Haijun Metal Products Co., Ltd. yakha izinto ezihlala ziyiqiniso lapho i-laser ishaya, hhayi nje lapho ingxenye ihlezi inganyakazi. Uma iphrojekthi yakho elandelayo idinga i-laser welding fixture ukwethembeka—hhayi nje ukubamba amandla—kuqala ngenjongo yobunjiniyela, hhayi izinombolo zekhathalogi. Ukunemba kuqala lapho ingxenye ihlangana ne-base plate.
