毕业设计进给箱齿轮轴.pdf

机电一体化专业 毕 业 设 计 （论 文） 机械制造工艺部分 题 目： 进给箱齿轮轴 系 别： 动力工程系 专 业： 机电一体化 班 级： 机电092班 学生姓名： 李春光 指导教师： 熊娟 韩丽娜 完成日期： 2012-05-06 四川电力职业技术学院 2012 届毕业设计 进给箱齿轮轴 进给箱齿轮轴机械加工工艺规程毕业设计 摘 要 进给箱用来改变进给量，主轴经挂轮箱传入进给箱的运动，通过移动 变速手柄来改变进给箱中滑动齿轮的啮合位置，便可使光杆或丝杆获得不 同的转速。 本文主要是给 “进给箱齿轮轴” 制订机械加工工艺规程。文章分别从 课题的来源及意义，毛坯的制造形式及尺寸，基准的选择，加工阶段的划 分以及工艺路径的拟定，加工余量还有尺寸的设计来进行介绍的。 关键词：齿轮轴，尺寸，设计工艺，加工基准， 设 计 人 ： 李 春 光 1 2012 届毕业设计 进给箱齿轮轴 目 录 1 绪论 ·······························································3 1 1 3 ． 选题背景······················································ 1．2 零件作用 ······················································3 2 毛坯的选择 ·························································3 2 1 4 ． 外圆表面尺寸的确定··········································· 2．2 外圆表面沿轴线长度方向加工余量及工差的确定···················4 2．3零件图························································4 2 4 5 ． 立体图························································ 3 基准的选择 ························································5 4 加工阶段的划分···················································6 4.1 粗加工阶段 ····················································6 4.2 半精加工阶段 ··················································6 4.3 齿轮加工阶段磨削加工阶段 ······································6 5 工艺路径的拟定··········································
