摘要本文介绍了汽车转向节设计制造的整个过程，其中机械工艺规程部分详细说明零件工艺分析，基准选择，工艺路线制定，加工经济度和加工方法的经济选择，加工阶段上述分析，毛坯的制造，拟定工艺路线，确定切削余量，毛坯决定的加工尺寸大小；机床夹具设计，机床夹具包括一些主要的夹具组成，夹具的类型，夹具的功能，工件在夹具上的位置，工件夹的夹紧，拉主销孔夹具设计，刀具设计部分包括的主要刀具，拉刀的设计特点，种类，拉削销孔的主要刀具的设计。有效的利用高效组合机床，不仅要效率，而且要确保该定位精度的要求，重点放在加工过程和减少定位误差，加工效率高。组合夹具，专有夹具，操作简便，缩短了辅助实践。合理有序的工序不足，以减少工件量，节约资源。拉削主销孔夹具采用摇板与支撑组成的自我定位的支撑，让拉刀在这个拉削过程中的切割保持和主销孔的同轴度。机构简单，易于操作，并确保准确和精度，拉削过程中就用一次行程可以完成拉削过程，提高加工效率。拉刀的设计采用了组合式来源空拉刀设计方法，拉刀的特点分析，类型，材料和其他问题，根据加工余量，大小，工件材料的设计需要的刀具。拉刀这种工具，具有高效率，高精密加工的特点，在机械加工中被广泛的加工应用。关键词转向节加工工艺工艺路线切削余量机床夹具夹具拉刀AbstaracThispaperdescribesthecarsectionofthemanufacturingprocesstodesignthewholeprocessofwhichmachineryoftheorderofthedetaileddescriptionofthepartsanalysis,thebenchmarkchoiceofroutedevelopment,precisionmachiningandprocessingmethodsofeconomicchoice,theprocessingstageoftheAnalysisroughthemanufacture,preparationoftheroad,determinedcuttingcushionandprocessingdeterminethesizeandrough;machinefixtureofthefunction,theworkpieceinthefixtureonthelocation,folderTight,pullthemainpinholefixturedesign,includingthemantoolofthedesigncharacteristicsofBroach,Broachtype,pinholeBroachingthemaintoolusedbydesign.Efficientuseofprocessingcombinationofmachinetools,notonlyefficient,butalsotoensurethatthelocationaccuracyrequirementsfocusonprocessesandreducethepositioningerrorprocessingefficiency.Acombinationoffixture,proprietaryfixture,easytooperate,shortenedthetimetosupport.Reasonableandorderlyprocessforstepstoreducetheworkload,savingresources.Broachingthemainpinholefixturewithashake-salessupportoftheself-targetedsupporttobroachinRafahintheprocessofcuttingitsownmaintainandbroachthemainlineofthepinhole.Bodiessimple,easytooperate,andensuretheaccuracyofprocessingBroachingprocesscanbecompletedinonetripBroachingprocess,theprocessingefficiency.BroachthedesignusingamodulardesignmethodsholeBroach,Broachanalysisofthecharacteristics,types,materialsandotherissues,accordingtothecuttingcsshion,size,theworkpiecematerialsdesignedfortool.Rafahprocessingtoolhashighefficiency,high-precisionmachiningcharacteristics,itwaswidelymachiningapplications.Keyword:Knuckle,technologicalmanufacturingdesign,thelineofthemanufacture,fixture,broach摘要................................................................................................................2ABSTARAC...................................................................................................3第1章绪言...................................................................................................6一制定工艺路线............................................................................................................6二夹具设计....................................................................................................................6三专用刀具设计........................................................
