Ukuyila a i-weld test fixture ayithethi malunga nokubopha iinxalenye kunye nethemba lokufumana iziphumo ezifanayo. Kumalunga nokwakha ukongezwa kwenjongo yobunjineli bakho-apho yonke indawo, iphini, kunye namandla okubamba aguqulela ngokuthe ngqo kumgangatho we-weld ophinda-phindayo, uzinzo lobungakanani, kunye nokuzithemba kokuhlola. E-Botou Haijun Metal Products Co., Ltd., sakhe ngaphezulu kwe-270 yesiko izixhobo zovavanyo lwe-weld kubaboneleli beemoto zeTier-1, izixhobo zezolimo ze-OEMs, kunye nezihlanganisi ezizenzekelayo kwimizi-mveliso. Kuzo zonke iimeko, ukusilela ukujongana neziseko zoyilo oluphambili kukhokelele kwesinye okanye ngaphezulu kwezi ziphumo: i-weld seams engalunganga, ukupasa kobuxoki / ukusilela ukufundwa ngexesha lokuqinisekiswa, okanye ukuphinda kusetyenzwe ngeendleko emva kokuqaliswa kwemveliso.
Yibethelele Inxalenye—Unganeli Nje Ukuyibamba
Uninzi lwamaqela aqala ngeqhinga lokubambelela-kodwa oko kusemva. Okokuqala, chaza iskimu se-datum usebenzisa indawo esebenzayo yecandelo: i-flange ekhulayo, i-mating boss, okanye ipateni ebalulekileyo yomngxuma echaza indlela icandelo elingena ngayo kwindibano yokugqibela. Sisebenzisa iingongoma ezintathu kwiindawo ezisisiseko, azizange zibe zine—kuba iingongoma ezine ziphembelela ukugqwetheka kwesinyithi esinegeyiji encinci. Kwisibiyeli esiqhelekileyo esenziwe kwi-2.0 mm yentsimbi epholileyo epholileyo, sicacisa izikhonkwane zedoweli eziqinileyo kunye nokunyamezela kwe-± 0.005 mm ububanzi, ukucinezela kwi-bushings yomhlaba ehleli kwiiplate zesiseko ze-aluminium 6061-T6. Kutheni i-aluminium? Isebenza ngomatshini ngokucocekileyo, ithomalalise ukungcangcazela ngexesha le-robotic welding, kwaye inobunzima obungama-60% ngaphantsi kwentsimbi yokuphatha umsebenzi. Sigwema iziseko zentsimbi etyhidiweyo ngaphandle kokuba ubunzima be-thermal bufunekayo kuvavanyo lwe-high-duty-cycle test-i-brittleness yayo ibeka ingozi ye-micro-fractures kufuphi nemingxuma edibeneyo emva kwemijikelezo ye-torque ephindaphindiweyo.
Lawula ukuKhula kweThermal-Ngaphambi koKubetha kweArc yokuQala
Ukuwelda kuvelisa ubushushu bendawo ukuya kuthi ga kwi-1500°C. Loo mandla akapheli-ayafuduka. Ayikhange iqwalaselwe, ijika izithuba zentsimbi, itshintshe indawo yephini ukuya kuthi ga kwi-0.08 mm, kwaye yenza yonke imilinganiselo elandelayo ingasebenzi. Ukulungiswa kwethu: i-alloy ye-alloy yobuchule ifaka kwiindawo ezikufutshane ze-weld. I-Copper's thermal conductivity (401 W / m · K) itsala ubushushu kude kahlanu ngokukhawuleza kune-aluminiyam. Sizinzise iibhloko zobhedu ze-OFHC ngokuthe ngqo phantsi kwee-weld joints, ezibotshelelwe ngezikrufu ze-M4 cap kwaye zodwa kwisakhiwo esingundoqo sisebenzisa i-0.5 mm PTFE shims. Oku ayisiyonto ithiyori-silinganise i-32% esezantsi ye-thermal drift kulo lonke uvavanyo lonyamezelo lomjikelo we-120 ngokuchasene ne-aluminiyam yonke. Ibhonasi: Ubume bobhedu obungenamagnetic buthintela ukuphazamiseka kwe-arc ngexesha lokuqinisekiswa kwe-TIG.
Yakhela uQinisekiso-Hayi nje Ukusetyenziswa
A i-weld test fixture kufuneka ingqine ukuchaneka kwayo. Uyilo ngalunye lubandakanya iimpawu zokuqinisekisa ezakhelwe ngaphakathi: iiflethi zereferensi ezichanekileyo (Ra ≤ 0.4 µm), iithagethi ze-CMM ezifikelelekayo kwi-callouts eziphambili ze-GD&T, kunye neebar zokulinganisa ezisusekayo ezilandelekayo kwimigangatho ye-NIST. Omnye umxhasi unyanzelise ukuba "kungabikho mingxunya ingaphezulu" -ngoko ke siye sasebenza ngoomatshini i-Ø6.35 mm iindawo ezingqukuva ezingqukuva kwindawo yokukhangela indawo. Aba bamkela isitayile esiqhelekileyo seCMM ngaphandle kweeadaptha kwaye baphile 10,000+ imijikelo yokuhlola. Siphinde sidibanise iiphaneli zokufikelela ngokukhawuleza kwiibhloko zangaphakathi zegeji, ukuvumela abaqhubi baqinisekise ubude bendawo ngaphakathi kwemizuzwana engama-90-kungekhona imizuzu engama-20 ukudiliza yonke indibano. Ukuba awukwazi ukulinganisa ukunyaniseka kwesixhobo ngokukhawuleza kunokuba uhlole inxalenye, uthemba ithamsanqa, hayi idatha.
Tshatisa Ukuqina kokuLungisa kwinkqubo yakho-hayi uHlahlo Lwakho
Ukuqina akukho malunga nobukhulu-ku malunga nomzuzu wokusabalalisa inertia. Ipleyiti yentsimbi eyi-30 mm engqindilili ibonakala iqinile de wongeze ingalo ye-cantilevered eyi-120 mm yokufikelela kwitotshi yerobhothi. Emva koko ukuphambuka kubetha i-0.12 mm phantsi kwe-45 N ye-welding force. Isisombululo sethu: ukwakhiwa komxube. Isiseko esingundoqo = 25 mm ubukhulu be-7075-T6 i-aluminium (amandla aphezulu-kuya-ubunzima). Iireyile ezibalulekileyo ze-locator = i-bonding steel stainless 304 strips (isivuno samandla 505 MPa). Umgca webhondi usebenzisa i-aerospace-grade epoxy kunye ne-0.05 mm gap elawulwayo-iqinisekisiwe nge-ultrasonic pulse-echo scanning. Oku kunikezela nge-2.3 × ukuphakama kwe-torsional ephezulu kune-aluminium ye-monolithic kwi-18% ubunzima obuphantsi. Siqinisekisa uyilo ngalunye kunye nohlalutyo lwe-FEA lwemodyuli ejolise kwi-frequency yokuqala yendalo> 120 Hz-ngaphezu kweendlela eziqhelekileyo zerobhothi ze-welding. Akukho resonance. Akukho drift. Akukho zizathu.
Yonke i-weld test fixture sihambisa iinqanawa ngephakheji ye-metrology epheleleyo: ingxelo ye-CMM eyakhiweyo, ijika le-thermal drift, kunye nesifundo sokuphindaphinda kubasebenzisi abathathu kunye neeshifti ezimbini. Kuba ukuchaneka ayisilo ibango lephepha elithile-yinto esindayo kusetyenziso lwehlabathi lokwenyani. I-Botou Haijun Metal Products Co., Ltd. yakha izixhobo zokuthemba iinjineli xa iindleko ze-scrap zidlula i-$ 1,200 ngeqela elibi le-weld. Ukuba yangoku i-weld test fixture ifuna uhlengahlengiso lwemihla ngemihla okanye iyasilela uphicotho lwe-GD&T emva kwemijikelo engama-500, isiphene asikho kwinkqubo yakho-sisesiseko. Qala apho.
