木窗加工指接机端面铣削部分设计说明书.doc

黑龙江工程学院本科生毕业设计I摘要本次设计的指接机端面铣削部分是应用于普及型欧式木窗加工的专用设备,通过指接技术降低类似于欧式木窗的木工产品的生产成本,提高其市场竞争力。通过对国内外指接设备的分析,在考虑生产成本的基础上,设计了能够满足一般指接需求的设备,并根据较小尺寸对刀具系统进行了完善,使本机床的刀具系统适用较小截面尺寸的木工产品的指榫加工。刀具主轴转速较高,并承受一定的扭矩,文中对其进行了受力分析,确保其在生产中的安全性,同时对其附属部分,如带传动和轴承等进行了校核计算。木材原料夹紧机构采用弹簧压紧,对弹簧力进行了分析,确保在最省力的情况下使木材原料顺利加工。本题目从生产实际出发,为小径木材指榫加工设计关键设备,对现有的指接机进行改进设计,降低指接生产线成本,使指接技术得以普及。对于我国中小型木工企业的生产改型和技术革新有重要的意义。关键词木材指接指榫欧式木窗木工机械黑龙江工程学院本科生毕业设计IIABSTRACTThemachinethatwedesignedisamillinginstallationwhichisusedforthemachiningofthepopularizedwesternstylewoodenwindow.Byapplyingthiskindofknowledge,wecouldreducetheproductioncostsofthoseproductsaswesternstylewoodenwindowandenhanceitscompetitivepower.Throughtheanalysisofboththedomesticandtheforeigntenonersandonthebasisoftheconsiderationofitsproductioncosts,wehavedesignedthiskindofequipmentwhichcouldmeettheneedforthejointofgeneraltenonneedrawmaterialsandhavemadeapprovementstoitstoolsystem.Throughthischange,wehavemadeitstoolsystemmoreapplicableforthejointofthoseproductsinsmallersectionsize.Thetoolsprimaryshaftworksinhigherrotationalspeedandwithstandscertaintorque.Wehavecarriedouttheforceanalysisinthisarticletomakesureitssecurityandhavemadecheckoutstoitsaccessorialparts,suchastransmissionbeltandtransmissionshaftandsoon.Throughtheanalysisofthespringforce,weusesthespringtocompactinthelumberrawmaterialjigsystemtomakesurethatthelumberrawmaterialscouldclampsmoothlyinthesituationwhichusestheminimumforces.Combinedfrominfactofproduct,thistopicissetupbothforthedesignofthekeyequipmentswhichareusedforthemachiningofthissmallmaterialsandtomakeapprovementstotheexistingtenonerssoastoreducethecostsoftheconnectproductionlineandtomakethistechniquepopular.Withregardtoourmiddleandsmallcarpentryenterprisesproductionmodificationandtechnicalinnovation,thisdesignhasquiteavitalsignificance.KeywordsLumberConnectTenonWesternstylewoodenwindowwoodworkingmachineny黑龙江工程学院本科生毕业设计目录摘要.........................................................................................................................................IAbtract...................................................................................................错误未定义书签。第1章绪论.......................................................................................................................11.1指接技术综述............................................................................................................11.2指接设备的研究意义................................................................................................11.3木工机械的国内外发展综述....................................................................................21.3.1木工机械产品的现状......................................................................................21.3.2木工机械发展趋势..........................................................................................21.4指接概述....................................................................................................................41.4.1指接工艺简介..................................................................................................41.4.2指接的特点......................................................................................................51.4.3指接材的种类..................................................................................................51.4.4指榫的加工方法..............................................................................................51.4.5指接机床的使用及加工缺陷的调整..............................................................61.4.6影响指接材质量的因素..................................................................................81.4.7指接材质量评定与检验..................................................................................91.4.8指接刀简介....................................................................................................10第2章指接机切削部分的设计方案.........................................................................132.1切削部分的设计任务..............................................................................................132.2切削部分的主要工作结构......................................................................................132.3指接机的开榫原理及工作方式..............................................................................132.4切削部分的设计方案..............................................................................................142.4.1机床的设计方案............................................................................................142.4.2工作要求........................................................................................................142.4.3产品的用途....................................................................................................152.4.4工段的生产制度和主要经济指标................................................................152.5本章小结..................................................................................................................15黑龙江工程学院本科生毕业设计第3章端铣系统的设计计算.....................................................................................163.1电动机的选择......................................................................................
