1、 毕毕 业业 设设 计计 （论文）（论文） 课题名称：课题名称：凸轮轴瓦盖钻孔加工夹具设计 专 业 机械设计制造及其自动化 班 级 学 号 学生姓名 指导教师 完成日期 I 摘摘 要要 这次毕业设计以凸轮轴瓦盖为主要加工对象,设计任务有两项,第一项是设计多轴 钻分动箱对凸轮轴瓦盖上表面两孔同时加工;第二项是设计零件的工装夹具（钻孔夹具 设计） .在对多轴钻分动箱的设计中,首选根据零件图对零件的机构、 技术要求进行分析， 然后根据被加工孔的位置分布，选择合适的传动方案，进而对设计组件进行设计计算, 最后完成箱体的结构设计. 本文钻削夹具设计的主要内容是，首先进行夹具方案设计， 接下来通过参考资料
2、、查阅标准及设计规范进行了定位部分设计、夹紧部分设计、夹具 体设计等，并对其定位误差、夹紧力进行了计算，最后完成其夹具装配图。多轴钻夹具 是配合立式钻床进行钻孔加工的工艺装备，利用钻床主轴驱动多轴头各个工作轴，配套 夹具进行夹紧和定位。在一次装夹过程中就可以完成若干孔位的加工，很适合大型汽车 厂内大批量加工零件上多个孔系的工序，可以显著提高生产效率。 关键词：关键词： 钻床夹具；多轴钻；定位 II Abstract The graduation design the camshaft cap design for the main target, there are two design ta
