组合机床主轴箱及夹具设计摘要:根据设计任务书的要求,本设计说明书针对连杆大小头双端面铣削组合机床的设计及专用夹具设计进行说明。主要内容包括组合机床工艺方案的制定、组合机床配置型式的选择、组合机床总体设计以及主轴箱设计。全文主要包括组合铣床的总体设计和主轴箱设计两部分。机床总体设计主要是在选定工艺方案并确定机床配置形式、结构方案基础上确定“三图一卡”，主轴箱设计根据“三图一卡”，整理编绘出主轴箱原始依据图，重点分析传动系统经过各种方案的比较，最后确定最优方案。此外，为了提高劳动生产率，降低劳动强度，保证加工质量，需设计专用夹具。关键词：主轴箱；组合机床；夹具ICombinationMachineToolSpindleboxesandfixturedesignAbstract:Accordingtodesignstheprojectdescriptiontherequest,Thisdesigninstructionbookletcarriesontheexplanationinviewoftheconnectingrodreducingsocketdoublefacemillingaggregatemachine-tooldesignandtheunitclampdesign.Maincontentincludingaggregatemachine-toolcraftplanformulation,aggregatemachine-toolconfigurationchoice,aggregatemachine-toolsystemdesignaswellasheadstockdesign.Thefulltextmainlyincludescombinesthemillingmachinethesystemdesignandtheheadstockdesignstwoparts.Theenginebedsystemdesignmainlyisinthedesignationcraftplanandthedeterminationenginebeddispositionform,inthestructureplanfoundationdetermined"athreechartscard",theheadstockdesignbasis"athreechartscard",reorganizesthecompilationtoleavetheheadstockprimitivebasischart,thekeyanalysistransmissionsystem,passesthrougheachkindofplancomparison,finallydeterminesthemostsuperiorplan.Inaddition,inordertoenhancethelaborproductivity,reducesthelaborintensity,guaranteedtheprocessingquality,mustdesigntheunitclamp.Keyword：headstock；aggregatemachine-tool；jigII目录第一章绪论........................................................11.1组合机床的特点..................................................11.2组合机床的分类和组成............................................11.3组合机床的方案选择.............................................2第二章组合机床总体描述.............................................32.1组合铣床工艺方案的制定..........................................32.2确定切削力、切削功率...........................................42.3组合机床配置型式的选择..........................................52.4影响总体布置的因素..............................................52.5组合铣床的总体分析——三图一卡..................................6III第三章组合机床主轴箱设计..........................................123.1主轴箱设计的原始依据...........................................123.2运动参数和动力参数的确定.......................................123.3主轴箱的坐标计算...............................................24第四章组合机床夹具设计............................................264.1组合机床夹具概述..............................................264.2定位支承系统概述...............................................27第五章总结........................................................30致谢..............................................................31参考文献...........................................................32IV第一章绪论1.1组合机床的特点组合机床是由大量的通用部件和少量专用部件组成的工序集中的高效率专用机床。它能够对一种（或几种）零件进行多刀、多轴、多面、多工位加工。在组合机床上可以完成钻孔、扩孔、铣削磨削等工序，生产效率高，加工精度稳定。组合机床与通用机床、其他专用机床比较，具有以下特点：（1）组合机床上的通用部件和标准零件约占全部机床零、...
