超聲波金屬焊接機工作前的準備事項

連lian接jie板ban是shi工gong程cheng起qi重zhong機ji常chang用yong的de零ling部bu件jian，主zhu要yao由you底di板ban和he四si個ge銷xiao柱zhu組zu成cheng。銷xiao柱zhu與yu底di板ban之zhi間jian采cai用yong環huan形xing角jiao焊han縫feng焊han接jie方fang式shi進jin行xing固gu定ding，以yi往wang的de焊han接jie方fang法fa采cai用yong手shou工gongCO2氣體保護加藥芯焊絲焊接工藝
，由於焊縫為環形角焊縫，因而手工作業時容易造成焊縫外觀質量差，焊接作業效率低、焊縫環線與焊接部位環線結合性差等缺點，容易造成“脫焊”等deng情qing況kuang，同tong時shi為wei保bao證zheng焊han縫feng外wai觀guan質zhi量liang
，焊han接jie後hou需xu要yao采cai用yong砂sha輪lun機ji對dui焊han縫feng進jin行xing打da磨mo，也ye容rong易yi造zao成cheng焊han接jie成cheng本ben的de增zeng加jia。通tong過guo分fen析xi
，決jue定ding該gai工gong件jian采cai用yong超chao聲sheng波bo金jin屬shu焊han接jie機ji進jin行xing焊han接jie作zuo業ye
，關guan鍵jian是shi需xu要yao設she計ji合he理li的de超chao聲sheng波bo金jin屬shu焊han接jie機ji操cao作zuo係xi統tong和he製zhi定ding合he理li的de焊han接jie工gong藝yi，確que保bao成cheng本ben質zhi量liang的de有you效xiao統tong一yi。
1.焊接機器人總體方案
根據連接板的尺寸、結jie構gou特te點dian以yi及ji焊han縫feng的de形xing式shi，考kao慮lv到dao底di板ban和he四si個ge銷xiao柱zhu是shi采cai用yong單dan麵mian焊han縫feng形xing式shi，焊han縫feng在zai工gong件jian上shang呈cheng規gui則ze性xing均jun勻yun分fen布bu，焊han接jie過guo程cheng不bu需xu要yao變bian位wei即ji可ke滿man足zu所suo有you焊han縫feng的de焊han接jie。為wei降jiang低di成cheng本ben和he提ti高gao效xiao率lv
，在zai進jin行xing焊han接jie機ji器qi人ren整zheng體ti方fang案an設she計ji時shi，決jue定ding不bu采cai用yong翻fan轉zhuan工gong裝zhuang等deng機ji器qi人ren周zhou邊bian設she備bei

，而er采cai用yong固gu定ding平ping台tai方fang式shi實shi現xian工gong件jian的de焊han接jie定ding位wei，同tong時shi為wei提ti高gao焊han接jie效xiao率lv
，超chao聲sheng波bo金jin屬shu焊han接jie機ji係xi統tong方fang案an采cai取qu一yi機ji雙shuang工gong位wei的de模mo式shi
，H型布置方式，如圖2所suo示shi
，即ji機ji器qi人ren本ben體ti固gu定ding在zai兩liang自zi製zhi焊han接jie工gong作zuo定ding位wei平ping台tai之zhi間jian
，工gong作zuo時shi一yi工gong位wei焊han接jie機ji器qi人ren對dui人ren一yi側ce工gong件jian進jin行xing自zi動dong焊han接jie，另ling一yi工gong位wei可ke以yi裝zhuang卸xie工gong件jian，交jiao替ti進jin行xing作zuo業ye，保bao證zheng機ji器qi人ren連lian續xu不bu停ting工gong作zuo。

3.焊接工藝的確定
焊接工藝采用富氬混合氣體+實芯焊絲代替原有的CO2氣體+藥芯焊絲，富氬保護焊接具有熔池可見度好，操作方便、適shi宜yi於yu全quan位wei置zhi焊han接jie，同tong時shi電dian弧hu在zai保bao護hu氣qi體ti的de壓ya縮suo下xia熱re量liang集ji中zhong
，焊han接jie速su度du較jiao快kuai，熔rong池chi小xiao，熱re影ying響xiang區qu窄zhai，焊han接jie變bian形xing小xiao，抗kang裂lie性xing能neng好hao，焊han接jie過guo程cheng中zhong在zai惰duo性xing氣qi體ti保bao護hu下xia，具ju有you焊han接jie質zhi量liang好hao的de特te點dian
，非fei常chang利li於yu焊han接jie過guo程cheng中zhong的de機ji械xie化hua和he自zi動dong化hua。但dan由you於yu電dian弧hu的de光guang輻fu射she較jiao強qiang

，因yin此ci在zai超chao聲sheng波bo金jin屬shu焊han接jie機ji總zong體ti方fang案an設she計ji中zhong，需xu要yao設she計ji弧hu光guang安an全quan防fang護hu裝zhuang置zhi進jin行xing安an全quan保bao護hu。為wei提ti高gao焊han接jie效xiao率lv，采cai用yong一yi次ci施shi焊han成cheng形xing的de工gong藝yi方fang法fa
，避bi免mian由you於yu超chao聲sheng波bo金jin屬shu焊han接jie機ji重zhong複fu定ding位wei而er造zao成cheng生sheng產chan效xiao率lv的de降jiang低di。
