加工中心复合排屑器结构设计

苏州科技学院本科生毕业设计（论文）I苏州科技学院毕业设计（论文）论文题目加工中心复合排屑器结构设计院系机械工程学院专业机械设计制造及其自动化学生姓名张明光学号11200136203指导教师殷振2015年6月8日苏州科技学院本科生毕业设计（论文）II加工中心复合排屑器结构设计摘要此次毕业设计题目是加工中心复合排屑器结构设计。目前，加工中心最广泛实用的自动排屑装置是刮板排屑器，这种排屑器排屑效率较高，排屑能力较强，且整体区域没有积屑死区，因而适应能力较强。但它排屑精度不高，较小的颗粒状切屑容易经刮板上的孔进入切削液的循环系统，从而影响加工。对于微小颗粒切屑的排屑方案，目前主要有纸带过滤与磁性分离两种。本课题目的是通过对几种排屑方式结构上的分析，比较其各自优缺点，并对其组合、改进使其能够实现应用在加工中心上的较为彻底的切屑过滤。在此过程中熟悉掌握一般机械结构的结构设计过程，并通过三维及二维图的形式呈现出来。本人主要进行整个机械系统的结构设计、传动设计，具体内容包括减速机的选型、V带传功设计、链条刮板结构设计、磁性排屑结构设计、滤纸排屑结构设计及排屑器外观、水箱结构设计。设计思路是从排屑机的性能和动作要求出发，并以国内的质量和技术性能接近设计要求的排屑机为基础，希望设计出市场需求的适用于加工中心的复合排屑装置。关键词加工中心；排屑装置；机械系统苏州科技学院本科生毕业设计（论文）IIIStructuredesignofcompositechipinmachiningcenterAbstractThegraduationdesigntopicistheprocessingcentercompoundchipbreakerstructuredesign.Atpresent,machiningcentermostwidelypracticalautomaticchipremovaldeviceisscraperchipthisrejectionchipchipremovalefficiencyishigher,rowcrumbsabilityisstronger,andtheregionasawholedidnotaccumulatechipdead,andstrongabilitytoadapt.However,thechipisnothigh,thesmallergranularchipiseasytocutintothecuttingfluidthroughtheholeinthescraper,andthusthemachiningprocessisaffected..Chipsolutionforsmallparticlesofchips,therearemainlytwokindsofmagneticseparationandfiltration.Thepurposeofthispaperisbasedonseveralrowsofchipstructureanalysis,comparestheirrespectiveadvantagesanddisadvantages,andthecombination,improvetheapplicationinmachiningcenterthoroughlyswarffiltrationcanbeachieved.Inthisprocess,familiarwiththestructureofthegeneralmechanicalstructuredesignprocess,andthroughtheformofthree-dimensionalandtwo-dimensionalmap.Mymaindesigncontentfortheentiremechanicalsystem,thestructure,thetransmissiondesign,selectionincludingmotor,reducerselection,Vbelttransmissiondesign,scraperchaintransmissiondesign,magneticrowchipstructuredesign,filterpaperscrapsdischargestructuredesignandrowchipappearance,watertanknodestructuredesign.Designthinkingisstartingfromtherowremovalmachineperformanceandthemovement,andtothenationalqualityandtechnicalperformanceclosetothedesignrequirementsofchipmachinebased,andhopeto苏州科技学院本科生毕业设计（论文）IVdesignmarketdemandformachiningcentercompositechipremovaldevice.Keyword：Machiningcenter，Chipdevice，Mechanicalsystem苏州科技学院本科生毕业设计（论文）V目录第一章绪论...........................................................................................................................11.1研究目的与意义.......................................................................................................11.2排屑器发展现状.......................................................................................................11.3排屑装置的发展趋势...............................................................................................3第二章粗屑排屑设计...........................................................................................................42.1总体方案的确定.......................................................................................................42.2电动机、减速机的选择：.......................................................................................52.3V带的设计计算.....................................................................................................62.4带传动方案的确定.................................................................................................62.5带传动设计计算.......................................................................................................62.6带轮的结构设计.......................................................................................................82.7链传动设计计算.....................................................................................................102.8链轮结构设计.........................................................................................................122.8.1主动链轮结构设计......................................................................................122.9刮板链设计..............................................................................................................152.10链轮轴的设计........................................................................................................172.10.1各轴运动与动力参数...............................................................................172.10.2轴4结构设计计算...................................................................................182.10.3轴5的设计计算.......................................................................................192.10.4轴6的设计计算.......................................................................................202.10.5轴6的校核..............................................................................................222.11轴承的校核...........................................................................................................23轴4上轴承的校核..............................................................................................242.12键的选择和校核...................................................................................................24轴4上链轮处的键..............................................................................................242.13排屑装置钣金结构设计.......................................................
