摘要摘要PAGEII摘要本文主要论述了柴油机连杆的加工工艺及其夹具设计。因为连杆是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。连杆承受的是冲击动载荷，因此要求连杆质量小，强度高。所以在安排工艺过程时，按照“先基准后一般”的加工原则。连杆的主要加工表面为大小头孔和两端面，较重要的加工表面为连杆体和盖的结合面及螺栓孔定位面。在夹具设计方面也要针对连杆结构特点比较小，设计应时应注意夹具体结构尺寸的大小等，最终就能达到零件的理想要求！关键词:连杆变形加工工艺夹具设AbstractAbstractAbstractAbstractThedieselconnectingrodtreatinghandicraftthemainbodyofabookhasbeendiscussedmainlyandtheirgripdesign.Becauseoftheconnectingrodisoneofdyadicengineofpistonandmaincompressionenginepart,whoselargerendholeandcrankshaftlinkup,thesmallheadholelinksupbythewristpinandthepiston,whoseeffectisthatthepistongaspressureistransmittedtothecrankshaft,collectcrankshaftgasindrivingbutsettingapistoninmotiontocompressacylinder.Beingthatthepolebearspoundsaliveload,requestconnectingrodmassisminortherefore,theintensityishigh.Thereforewhenarrangingprocedurefor,accordingto"firstthecriterionqueen-like"treatingprinciple.Theconnectingrodmainpartprocessesasurfacebeingthatheadholeandbothendsbigorsmallareweak,moreimportantfayingfaceandboltholelocatingsurfacebeingtheconnectingrodbodyandcovertreatingoutside.Alsoshouldbecomparativelysmallspecificallyforconnectingrodstructurecharacteristicinthefieldofgripdesign,designthatthesizeshouldpayattentiontogrippingtheconcretestructuredimensionoftheseasonwaits,theidealbeingthereforelikelytoreachapartultimatelydemands!Keyword:ConnectingrodDeforminationProcessingtechnologyDesignofclampingdevice目录目录目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc275630563"摘要PAGEREF_Toc275630563\hIHYPERLINK\l"_Toc275630564"AbstractPAGEREF_Toc275630564\hIIHYPERLINK\l"_Toc275630565"第一章柴油机连杆的加工工艺PAGEREF_Toc275630565\h1HYPERLINK\l"_Toc275630566"1.1柴油机连杆的用途及其特点PAGEREF_Toc275630566\h1HYPERLINK\l"_Toc275630567"1.2连杆的的材料及毛坯制造PAGEREF_Toc275630567\h1HYPERLINK\l"_Toc275630568"1.3连杆的加工工艺过程PAGEREF_Toc275630568\h2HYPERLINK\l"_Toc275630569"1.4连杆的加工工艺过程分析PAGEREF_Toc275630569\h2HYPERLINK\l"_Toc2
