滑块加工工艺及夹具设计说明书

重庆交通大学学士学位论文摘要本次毕业设计针对滑块工艺规程进行设计，涉及滑块的选材、确定毛坯和机械加工余量及工序尺寸与公差、拟定工艺路线、选择工艺设备；并进行切削用量和时间定额的计算，填写机械加工工艺过程卡和机械加工工序卡片。为了保证加工质量，提高生产效率，对关键工序进行夹具设计。本文对夹具的工作原理、作用、分类和组成做了简单概述；着重分析了工序特点和要求，根据结果确定定位方案，设计定位元件、夹紧机构、对刀元件和夹具体。因此，保证了加工精度和设计质量。关键词：滑块；工艺规程设计；夹具设计；生产规划重庆交通大学学士学位论文AbstractThispapercarriesonthedesigninviewoftheslidertechnologicalprocess,involvestheselectionoftheslider,thedeterminationofsemi-finishedmaterials,themachiningallowance,theworkingproceduresizeandthecommondifference.Idrawupthesliderroute,andchoosetheprocessunit.AndthenIcarryonthecomputationofthecuttingspecificationsandthetimenorm,nextIfillabove-mentionedresultsinmachine-finishingtechnologicalprocesscardandthemachine-finishingworkingprocedurecard.Inordertoguaranteetheprocessingqualityandenhancetheproductionefficiency,Icarryoutthejigdesigntotheessentialworkingprocedure.InthispaperIhavemadethesimpleoutlinetotheoperatingprinciple,thefunction,theclassificationandthecompositionofthejig.Ihavealsoemphaticallyanalyzedthecharacteristicandtherequestoftheworkingprocedure,determinedthelocalizationplanaccordingtotheresult,anddesignedthelocalizationpart,theclamporganization,theguidingcomponentandthejigbody.Therefore,theprocessingprecisionandthedesignqualityhavebeenguaranteed.Keywords:slider；Technologicalprocessdesign；Jigdesign；Productionplan重庆交通大学学士学位论文I目录第1章绪论..........................................................................................11.1滑块加工技术现状及发展方向..............................................................................11.2本课题研究的目的、意义......................................................................................21.3课题的主要内容......................................................................................................2第2章滑块的机械加工工艺规程设计...............................................................................42.1滑块的工艺分析及生产类型的确定......................................................................42.1.1滑块概述........................................................................................................42.1.2滑块零件的技术要求....................................................................................42.1.3确定滑块的生产类型和工艺特征分析........................................................62.2滑块的材料和毛坯确定..........................................................................................72.2.1滑块毛坯材料、加工方法及技术要求........................................................72.2.2滑块毛坯的尺寸公差和机械加工余量........................................................82.2.3绘制滑块毛坯简图......................................................................................102.3拟定滑块工艺路线................................................................................................102.3.1定位基准的选择..........................................................................................102.3.2表面加工方法的确定..................................................................................102.3.3加工阶段的划分..........................................................................................112.3.4加工工艺路线方案确定..............................................................................112.4机床设备及工艺装备的选用................................................................................112.4.1机床设备的选用..........................................................................................112.4.2工艺装备的选用..........................................................................................122.5加工余量、工序尺寸及其公差的确定................................................................132.6确定切削用量及时间定额....................................................................................142.6.1切削用量的计算..........................................................................................142.6.2时间定额的确定..........................................................................................162.7填写工艺文件........................................................................................................17第3章机床夹具设计........................................................................................193.1机床夹具设计概述................................................................................................193.1.1夹具的主要工作原理..................................................................................203.1.2夹具的作用..................................................................................................203.1.3机床夹具的分类..........................................................................................203.1.4专用机床夹具的组成..................................................................................203.2机床夹具设计........................................................................................................213.2.1问题的提出..................................................................................................213.2.2定位方案及定位元件选择和设计..............................................................213.2.3确定夹紧方式、设计夹紧机构..................................................................223.2.4设计对刀元件、连接元件及夹具体..........................................................223.2.5绘制夹具总图及零件图...........
