激光切割机所设计

A1A0A2A3A4A5A6A7A8A9A11A101摘要激光切割技术广泛应用于金属和非金属材料的加工中，可大大减少加工时间，降低加工成本，提高工件质量。脉冲激光适用于金属材料。本工作台专为光大CDYAGAC200/400/500激光切割机所设计。激光切割机在工作过程中仅为YY方向移动则可，可切割小于3MM厚的金属片，打孔，等。其切割路线由CAD图纸直接传输，可切割一些不规则的路线。由于激光切割为特种加工技术，在切割过程中并无切割力的作用，因些在工作台设计方面，可以不考虑切削力的影响。机械系统应具备良好的伺服性能（即高精度、快速响应性和稳定性好）从G13792G16213G8726本G8437设计传动机G7512G9397G17287以G991G1972方面G726（G20）G17728动G5827量小（2）G2030度大（3）G19471G4624G2524适G8504G3818G17836G16213G8726G6717G6842小（提高机G7512的G9801G6947度）、G1861G6403性好（提高机G7512的稳定性）、间G19565小（G1457G16789机G7512的传动精度），特G2047G7171其动G5589特性应G994伺服G11017动机等其G4439G10627G14422的动G5589特性G11468G2317G18209。设计过程中G1039G16213G4557工作台的G1009G7476，G4560G17724，G11017机，以G2462G2331降机的G2454G6980G17839G1849G17885G6333设计，以G2462工件的G13864接设计等。G2528时G13484G2058G2520G1039G16213工件的G19658件图和工作台G16025G18209G5647图，设计其中G18337G16213工件的加工工G14414规程。G1863G19202G4395G29工作台机械设计激光技术切割机A12A13A14A15A16A17A18A19A20A21A22A232ABSTRACTLASERCUTTINGTECHNOLOGYWIDELYUSEDINMETALANDNONMETALLICMATERIALSPROCESSING,CANGREATLYREDUCETHEPROCESSINGTIME,LOWERPROCESSINGCOSTSANDIMPROVETHEQUALITYOFTHEWORKPIECEPULSEDLASERAPPLIEDTOMETALMATERIALSTHETABLEFORTHECHINAEVERBRIGHTCDYAGAC200/400/500LASERCUTTINGMACHINEDESIGNEDLASERCUTTINGMACHINEINTHECOURSEOFTHEIRWORKCANBEMOVEDONLYYY,CUTTINGLESSTHAN3MMTHICKMETALSHEETS,PUNCHING,ANDSOONITSCUTTINGLINEDIRECTLYFROMCADDRAWINGSTRANSMISSION,CUTTINGSOMEIRREGULARROUTESSINCELASERCUTTINGFORSPECIALPROCESSINGTECHNOLOGIES,INTHEPROCESSOFCUTTINGNOROLEINCUTTINGEDGE,THEMORETHEDESIGNOFTHETABLE,YOUCANNOTCONSIDERTHEIMPACTOFCUTTINGFORCEMECHANICALSYSTEMSSHOULDHAVEAGOODSERVOPERFORMANCETHATIS,HIGHPRECISION,RAPIDRESPONSEANDSTABILITYTOREQUESTTHETRANSMISSIONMECHANISM,DESIGNEDTOMEETTHEFOLLOWING1SMALLMOMENTOFINERTIA2THESTIFFNESS3SUITABLEDAMPINGFRICTIONALSOREQUIRESMALLINCREASETHESENSITIVITY,THERESONANCEOFGOODIMPROVETHESTABILITYOFINSTITUTIONS,THESMALLSPACETHETRANSMISSIONENSUREACCURACY,INPARTICULARITSDYNAMICCHARACTERISTICSWITHTHESERVOMOTORANDOTHERLINKSTOTHEDYNAMICNATUREOFMATCHTHEPROCESSOFDESIGNINGTHEMAINTABLEOFTHESCREW,RAILS,THEELECTRICALANDLIFTTHEPARAMETERSINTOTHECHOICEOFDESIGN,ANDPARTSOFTHELINKDESIGNATTHESAMETIMEDRAWINGALLTHEMAJORPARTSOFTHEASSEMBLYPARTSMAPANDTHEMAPTABLE,ONEOFTHEMAJORPARTSOFTHEDESIGNOFPROCESSINGAPOINTOFORDERKEYWORDSTABLEMECHANICALDESIGNLASERTECHNOLOGYCUTTINGMACHINEA24A25A26A27A28A29A30A31A32A33A34A353前言1激光原理激光G14533G7003G1852G2529为G47G76G74G75G87AMG83G79G76G73G76G70G68G87G76G82G81G69G92G54G87G76MG88G79G68G87G72G71G40MG76G86G86G76G82G81G82G73G53G68G71G76G68G87G76G82G81G11G47AG54G40G53G12。于G20G28G250G5192面G1002，G7171一种因G2062激G1147G10995G17764G4568G13792G5390G2282的光。G12197G4410G4490在G11017G12661中以光G6122G11017G8981的能量G7481G6770G1999G7588些G7242G1319G6122G2419G4388G7143G2475激G2469的G10301质，G1363其G2419G4388的G11017G4388G17810G2052G2475激G2469的高能量状G5589，当这些G11017G4388G16213回复G2052平静的低能量状G5589时，G2419G4388就会G4568出光G4388，以放出多余的能量；G13792接着，这些被放出的光G4388又会G6770G1999其G4439G2419G4388，激G2469更多的G2419G4388G1147G10995光G4388，引G2469一连串的连锁反应，并且都朝G2528一个方前G17839，形成G5390烈G13792且集中朝向G7588个方向的光；因G8504G5390的激光甚至可用作切割钢板2激光加工技术激光G717120G1002纪G250G5192代的新光源。由于激光具有方向性好、亮度高、单色性好等特点G13792得G2052广泛应用激光加工G7171激光应用最有G2469展前途的领域之一，现在已开G2469出20多种激光加工技术。激光切割G7171应用激光聚焦后G1147G10995的高功率密度能量G7481实现的。在计算机的控G2058G991，通过脉冲G1363激光器放G11017，从G13792输出G2475控的G18337复高频率的脉冲激光，形成一定频率，一定脉宽的光束，该脉冲激光束经过光路传G4560G2462反G4568并通过聚焦透镜组聚焦在加工G10301G1319的表面上，形成一个个细微的、高能量密度光斑，焦斑位于待加工面附近，以瞬间高温熔G2282G6122气G2282被加工材料。每一个高能量的激光脉冲瞬间就把G10301G1319表面溅G4568出一个细小的孔，在计算机控G2058G991，激光加工头G994被加工材料按预先G13484好的图形G17839行连续G11468G4557运动打点，这样就会把G10301G1319加工成想G16213的形状。切割时,一股G994光束G2528轴气G8981由切割头喷出，将熔G2282G6122气G2282的材料由切口的底部吹出G11注G726如果吹出的气G1319和被切割材料G1147G10995热效反应,则G8504反应将提供切割所需的附加能源；气G8981G17836有冷却已切割面，减少热影响区和G1457G16789聚焦镜不G2475污染的作用G12。A24A25A26A27A28A29A30A31A32A33A34A354一、总体设计方案11设计任务X方向行程G29300MMY方向行程G29300MM工作台面的G2454考尺寸G29300X300MM最高运动速度G29G20400MM/MG76G81定位精度G29002MM工作寿G2641G29每G3837G27小时,工作G27G5192,300G3837/G519212机构要求机械系统应具备良好的伺服性能（即高精度、快速响应性和稳定性好）从G13792G16213G8726本G8437设计传动机G7512G9397G17287以G991G1972方面G726（G20）G17728动G5827量小在不影响机械系统G2030度的前提G991，传动机G7512的质量和G17728动G5827量应G4625量减小。G2554则，G17728动G5827量大会G4557系统G17908成不良影响，机械G17139G17745G3698大；系统响应速度降低，G9801G6947度G991降；系统G3278有频率减小，G4493G7143G1147G10995G16868G6403。所以在设计传动机G7512时应G4625量减小G17728动G5827量。（2）G2030度大G2030度G7171G1363G5389性G1319G1147G10995单位G2476形量所需的作用力。大G2030度G4557机械系统G13792G16340G7171有G2045的G726G311伺服系统动力G6451G3845G19555之减小。G312机G7512G3278有频率高，G17241出机G7512的频G5114宽度，G1363之不G7143G1147G10995G1861G6403。G313G3698加G19393G10627伺服系统的稳定性。所以在设计时应G17885用大的G2030度的机G7512。（3）G19471G4624G2524适机械系统G1147G10995G1861G6403时，系统的G19471G4624G3698大，其最大G6403G5145就G17246小且G15940减G1075快，G1306大G19471G4624G1075会G1363系统的稳G5589G16835G5058G3698大，精度降低，所以设计时，传动机G7512的G19471G4624G16213G17885着适当。G8504G3818G17836G16213G8726G6717G6842小（提高机G7512的G9801G6947度）、G1861G6403性好（提高机G7512的稳定性）、间G19565小（G1457G16789机G7512的传动精度），特G2047G7171其动G5589特性应G994伺服G11017动机等其G4439G10627G14422的动G5589特性G11468G2317G18209。G5647G1319设计如图G202G20所G12046G726A36A37A38A39A40A41A42A43A44A45A46A475方向传动机构方向传动机构电机步进电机步进电机微机控制图G202G2013设计方向确定XY工
