内容简介：

摘 要本次毕业设计的题目是卷纸机卷纸缸缸盖的工艺工装。我主要需要完成的包括加工工艺的安排以及专用的钻床夹具设计。为了保证加工零件的精度同时节约成本和缩短加工周期以及提高加工效率，那么一个良好的工艺安排以及专用夹具的设计就是必不可少的了。在工艺的安排上不但要考虑合理的加工要求还要考虑到操作者以及加工机械的安全。同时夹具的设计上也要考虑到使用的安全性和经济性以及安装和拆卸上的方便性。设计一个良好的工艺工装安排路线那么必须要经过对加工件的详细分析以及周密的考虑后才能得出。所以分析问题是解决问题的关键，同时还要反复的调整，来寻求最好的一个路线。这样才能让工艺路线更加的完美，才能保证工件的加工精度和加工效率以及节约材料。关键词 加工工艺；专用夹具；加工精度；工艺路线AbstractThe graduation design is the subject of cylinder head roll of paper machine process tooling. I mainly need to complete including Processing craft arrangement as well as special-purpose drill jig design.In order to guarantee the processing components the precision Simultaneously saves cost and the reduction processing cycle as well as the enhancement processing efficiency, Then a good craft arrangement as well as unit clamps design was essential. Not only in the craft arrangement must consider that the reasonable processing request also needs to consider the operator as well as processes machinerys security. Simultaneously jigs design also needs to consider the use in secure and efficient as well as the installment and the disassemblage conveniences. Designs a good craft work clothes arrangement route that to probably pass through to the job multianalysis,After as well as thorough consideration, can obtain. Therefore the analysis question solves the question key, meanwhile must the repeated adjustment, Seeks a best route. Seeks a best route to be able to let craft route even more perfect like this, can guarantee that the work piece the working accuracy and the processing efficiency as well as save the material.Key word Processing craft; Unit clamp; Working accuracy ; Craft route目 录摘要 Abstract 绪论 11 工艺工装设计任务 32 零件的技术要求分析 4 2.1 零件的材料性能分析 4 2.2 零件的形状及尺寸分析 4 2.3 零件的工艺要求分析 53 零件毛坯选择及毛坯图设计 63.1 确定毛坯的类型及制造方法 63.2 确定毛坯形状、尺寸及公差 64 机械加工工艺规程的制定 7 4.1 主要加工表面定位基准的选择 7 4.1.1 粗基准的选择 7 4.1.2 精基准的选择 7 4.2 拟定机械加工工艺路线 8 4.2.1 确定各加工表面的加工方法 8 4.2.2 拟定加工工艺路线 8 4.2.3 工艺路线分析比较 94.3 确定机械加工工序余量、工序尺寸及表面粗糙度 94.4 选择机械加工设备及工艺设备 94.5 切削用量及参数确定 94.5.1 背吃刀量 104.5.2 进给量 104.5.3 切削速度 105 夹具设计 115.1 夹具的特点 115.2 研究夹具的目的和义 115.3 夹具在国内外的现状和发展趋势 125.4 夹具总体方案的确定 135.4.1 定位方案及定位元件的选择 135.4.2 夹紧方案及夹紧元件的选择 145.4.3 夹紧力的计算 155.4.4 夹具的安装及导向机构的选择
