Uyilo lwe-robotic welding alukho malunga nokubopha iindawo kwipleyiti. Kumalunga nokuphelisa iyantlukwano ngaphambi kokuba irobhothi ide ihambise i-axis yayo yokuqala. Siye sabona imigca yemveliso emininzi kakhulu-hayi kwiirobhothi eziphosakeleyo okanye ucingo olubi-kodwa ngenxa yokuba ukulungiswa kuvumela ukuba inxalenye itshintshe i-0.12 mm ngexesha lokubamba. Olo tshintsho luncinci ludibanisa iiwelds ezingama-300, lujike unyamezelo oluyi-±0.5 mm lube linqanaba lokulahlwa ngaphezulu kwe-18%. Ukuchaneka kuqala apho intsimbi idibana khona.
Kutheni izilungiso "ezilungile ngokwaneleyo" zisilela phantsi kwe-Automation
I-welding ye-manual inyamezela ukulungiswa kwabaqhubi. Umshiseli onesakhono ubuyekeza intshukumo yamalungu amancinci, uhlengahlengisa i-engile yetotshi ekubhabheni, kwaye ifunde ukugqwetheka kobushushu njengolwimi lomzimba. Iirobhothi azivumelani-ziyaphinda. Ukuba i-robotic welding fixture yakho ayinayo indawo yokubeka ephinda-phindayo, ukunyanzeliswa koxinzelelo olungaguquguqukiyo, okanye imbuyekezo yokwandisa i-thermal, awuzenzi ngokuzenzekelayo umgangatho we-weld-uzenza ngokuzenzekelayo ukungangqinelani.
Sihlala siphicotha izinto eziziswe ngababoneleli beemoto beTier-1. Awona manqaku axhaphakileyo angaphumeleli? Iindawo zePin-and-bush zinxitywa ngaphaya kwemida ye-ISO 2768-mK. I-Spring-loaded clamps kunye ne-22% yokubola kwamandla emva kwemijikelezo ye-4,000. Iipleyiti ezisisiseko zixutywe ukusuka kwi-heat dissipation engalinganiyo-kulinganiswa ukuya kuthi ga kwi-0.35 mm ukuphambuka kwi-1.2 m ububanzi. Ezi ayizizo iimeko ezinzima. Ziingcambu ezibangela emva kwe-63% yenqaku lokuqala lokuphinda siphinde silibone ekuqalisweni kwenkqubo entsha.
Ukusebenza kwehlabathi lokwenyani kufuna ngaphezulu kolungelelwaniso lweCAD. Ifuna ukuqonda ukuba intsimbi eqengqelekayo ibanda kangakanani nge-12.5 µm/m·°C xa ithelekiswa ne-stainless kwi-17.3 µm/m·°C—kwaye nokuyila iindlwane zeendawo ezihlala zombini ngaphandle kokwazisa i-parasitic stress. Kuthetha ukucacisa izikhonkwane zedoweli ezingama-60 ze-HRC eziqinisiweyo endaweni yezikhonkwane ezisemgangathweni ezingama-45 ze-HRC xa ubalo lomjikelo lungaphezu kwama-50,000. Kuthetha ukuqinisekiswa koxinzelelo lwe-clamping nge-square millimeter-hayi nje itoni epheleleyo-usebenzisa iiseli zomthwalo olinganisiweyo ngexesha lokufaneleka.
ImiGaqo emine yoYilo lweFixture engaxoxisiyo
Yonke into enokuthenjwa ngokuphezulu kwe-robotic welding esiyakhayo ilandela le migaqo ingqinwe ebaleni:
Indawo enamaNqaku amathathu, hayi isine: Ukunyanzeliswa ngokugqithisileyo kubangela ukubophelela. Sisebenzisa i-kinematic mounting: izikhonkwane ezimbini zedoweli ezichanekileyo + umhlaba omnye osicaba, zonke zingqinwe nge-CMM ngokuchasene nee-callouts ze-GD&T-hayi nje ukuprintwa komda. I-Clamp Force> Amandla Okwandiswa kweThermal: Kwiqondo lokushisa eliphezulu le-weld (ukuya kwi-1,400 ° C kwi-nugget), ukwandiswa kwezinto ezisisiseko kunokuvelisa i-1,200 N ye-lateral force kwi-bracket ye-300 mm. I-clamps yethu ihambisa ≥2.5 × loo mandla amancinci okubamba, alinganiswe ngokuguquguqukayo-kungekhona i-statically-kwi-120 ° C ambient. Ujongano lweModyuli, hayi iMonolithic Yakhiwo: Ixesha lokutshintsha libulala i-ROI. Sidibanisa iipateni zokuxhoma ze-ISO 841-3 ezisemgangathweni kunye nokuqhawula ngokukhawuleza imigca yokupholisa. Umndilili wokutshintsha wehla ukusuka kwimizuzu engama-92 ukuya ngaphantsi kwemizuzu eli-14 kwiindawo ezili-17 zabathengi. Ulawulo lwe-Weld Spatter njengoMsebenzi oPhambili: I-Spatter ayiyonkunkuma-kungcoliseko oluqhubayo. Sizinzisa amakhaka e-copper-copper, atshintshelwe kwisitshizi ngokuthe ngqo kwimizimba ye-clamp kwaye siyibeke ngaphakathi kwe-8 mm yendawo nganye ye-weld. Idatha yendawo ibonisa oku kunqunyulwa kwetotshi yokucoca rhoqo nge-70% kwaye yandisa ubomi obusebenzisekayo nge-2.3 ×. Indlela Ukhetho Lwezinto Ezibonakalayo Oluyitshintsha Ngayo Yonke Into
Izixhobo ze-Aluminiyam zibukeka zibukeka-kodwa zisilela ngokukhawuleza kwiindawo eziphezulu zomjikelo. Silandele iiyure ezili-10,000+ zokusebenza kwiintsapho ezintathu eziphathekayo:
Intsimbi eyi-4140 eyenziwe yaQiniswa (28–32 HRC): Ingcono kwi>200,000-yeenkqubo zomjikelo. Uzinzo lweDimensional lubambe ngaphakathi kwe-± 0.015 mm ngaphezu kweenyanga ezili-18-nokuba kunye nokuhamba ngebhayisikile ye-thermal yemihla ngemihla. I-Stainless 17-4PH (H900): Ikhethwa kwibakala lokutya okanye kwindawo ezonakalisayo. Igcina ukuchaneka kwendawo emva kweeyure ze-5,000 zetyuwa-kodwa ixabisa i-3.2 × ngaphezu kwe-4140. Intsimbi yokuphosa EN-GJS-600-3: Isetyenziselwa kuphela iindibano ezinkulu (>2.5 m). Idambisa ukungcangcazela ngcono kunentsimbi-kodwa ifuna isiqabu soxinzelelo lweyure ezingama-72 emva komatshini. Asikhe sichaze izinto ezisekelwe kwindleko kuphela. Xa umxhasi wasicela ukuba sitshintshe ukusuka kwi-4140 ukuya kwi-aluminiyam ukugcina i-$ 1,200 ngomdlalo, siqhube umqhubi weenyanga ezi-3. Isiphumo: Ukunyuka kwe-4.8% kwi-weld porosity, i-11% yokusetyenziswa kwe-electrode ephezulu, kunye ne-3.2 yokuyeka ukugcinwa okongeziweyo kwishifti nganye. “Ugcino” lwaphela kwiveki yesibini.
IProtokholi yoQinisekiso lweBotou Haijun
Izinto zethu zithunyelwa ngobungqina obubhaliweyo—hayi izithembiso. Yonke iyunithi ifumana:
Ukuqinisekiswa kwangaphambili kwe-CMM yayo yonke imiphezulu yendawo (i-ASME B89.1.10M-2018 iyahambelana) I-Clamp force mapping kulo lonke uluhlu olupheleleyo lokuhamba usebenzisa i-piezoelectric sensor grids Uvavanyo lomjikelo we-Thermal: imijikelo engama-50 ukusuka kwi-20 ° C ukuya kwi-180 ° C, ukulinganisa i-locator drift kwinqanaba ngalinye. Ukomisa umgca wemveliso: Imijikelo engama-200 elandelelanayo eneendawo zokwenyani, ijongwe kusetyenziswa i-laser displacement sensors. Oku asikobunjineli obugqithisileyo. Ikhusela iindleko ze-247,000 zeedola zokuyeka umgca wemveliso omnye obangelwa ukulungiswa okungalunganga okubangelwa ukulungiswa. I-Botou Haijun Metal Products Co., Ltd. yakha iinkqubo ze-robotic welding fixture eziphila-kungekhona nje ukusebenza-kwiifektri zangempela. Sisebenza kwisiXeko saseBotou, kwiPhondo laseHebei, apho isinyithi esibumba ukubanda silinganiswa ngee-microns, hayi iimilimitha. Indawo yethu ethobela i-ISO idibanisa isitampu, ukugoba, ukuwelda, kunye ne-metrology phantsi kophahla olunye-ngoko akukho handoff ithoba ukunyamezela ukupakisha. Sihambisa ingxelo yobunjineli ngeentsuku ezintathu zokusebenza. Iikowuteshini zifika ngaphantsi kweeyure ezingama-48. Kwaye ukuba i-fixture ayibambi ± 0.02 mm ngaphezu kwemijikelo ye-10,000, siphinda siyisebenze-akukho ngxoxo.
Ngenxa yokuba ukuchaneka akusiyo inkcazo. Ngumsantsa phakathi kwento irobhothi ecinga ukuba iyayenza-kwaye yintoni eyenzeka ngokwenene kwinxalenye. Vala loo msantsa. Qala ngesixhobo.
