杠杆工艺和工装设计VIP专享VIP免费

摘要本设计的零件为杠杆零件，选用⒋⒌号钢。根据零件的形状、尺寸精度、生产的经济效益等各方面的详细分析其加工工艺，多采钻床加工。通过对零件的分析，此工件外形轮廓尺寸小，重量轻，加工要求不高，生产批量不大。因此在保证质量和提高生产率的前提下，尽量简化结构，做到经济合理。关键词：钻床加工，杠杆零件，尺寸精度。AbstractThedesignofpartsfortheleverpartsof45steel.Accordingtopartsofshape,dimensionalaccuracy,cost-effectiveproductionareassuchasadetailedanalysisofitsmanufacturingprocesses,MostDrilling.Partoftheanalysis,theshapeoftheworkpiececontoursmallsize,lightweight,low-processing,notmassproduction.Thereforethequalityassuranceandproductivity,underthepremiseofthestructureassimpleaspossible,soeconomicallyrational.Keywords:Drilling,leveragedparts,dimensionalaccuracy。目录摘要：..................................................................................................................................1前言.....................................................................................................................................3绪言.....................................................................................................................................41毕业设计的目的.......................................................................................................42毕业设计的基本任务与要求................................................................................42.1设计基本任务........................................................................................................42.2设计要求.................................................................................................................43毕业设计说明书的编写..........................................................................................5杠杆零件工艺设计与工装设计.............................................................................51.基本任务：...............................................................................................................52.设计要求：...............................................................................................................63.方法和步骤：...........................................................................................................63.1生产纲领.................................................................................................................63.2零件图审查.............................................................................................................64.钻床夹具设计...........................................................................................................74.1设计任务.................................................................................................................74.2设计方法和步骤....................................................................................................84.3夹紧装置的设计..................................................................................................124.4导向装置的设计及其他装置结构.夹具体的确定......................................154.5绘制夹具结构图..................................................................................................174.6确定夹具技术要求和有关尺寸，公差配合................................................174.7夹具精度分析与计算.........................................................
