三江学院本科生毕业设计（论文）题目汽车后轮毂八轴钻孔头设计 高职院 院（系部） 机械制造及其自动化专业学生姓名 学号 G095152032 指导老师 职称 助 教 指导老师工作单位 三 江 学 院 起讫日期 2012年12月17日—2013年4月5日 摘 要多轴头主要用于快速钻孔。是目前国内刚兴起的一种提高生产效率、降低成本的工作母机。随着国内汽配行的发展，各零部件供应商之间竞争激烈，选择一种高性能、高效率的机床是企业降低生产成本、提高企业竞争力的一种行之有效的途径。所以，多轴头在轿车上中小型零件类孔系加工中心的应用。即是值得推广的一项应用技术。多轴钻床在生产中的应用，解决了普通钻床加工多孔工件时逐孔加工浪费时间和人工这两个重要问题。本设计设计一台安装于立式钻床做535上的汽车轮毂八轴钻孔头，多轴头齿轮传动系统的设计，即保证工艺要求，又要考虑多轴头结构的紧凑型。传动系统设计良好，可使多轴头的结构灵活，各个轴受力情况良好，从而能减小齿轮、轴和轴承的磨损，延长多轴头的寿命。此外，我们对于传动部件进行了详细的参数和结构设计，并且对传动件进行了强度和刚度验算，使其达到设计技术精度。其中特别对齿轮、轴、滚动轴承等进行了具体的计算和验证来确定已达到设计要求。关键词：多轴头；轮毂钻孔；设计。AbstractMulti-axis head is mainly used for fast drilling. Is just the rise of a domestic increase productivity, reducecosts of machine tools. With the development of domestic auto parts firms, the fierce competition among partssuppliers, select a high-performance. high-efficiency machines are enterprises to reduce production costs andimprove the competitiveness ofenterprises an effective means. Therefore, the multi-axis head part in the bridge onthe category of small and medium holes of the application. That is a worthy application of technology. Multi-axisdrilling application in production to solve the general processing of porous workpiece by drilling holes a waste of time and manual processing of these two important issues.The design for the design of a vertical drilling machine installed in the Z535 Wheel 8 on the drilling head axis, multi-axis head gear transmission system design, that is, to ensure the process requirements. Have to consider firstthe structure of multi-axis compact. Transmission system design well, make smart multi-axis head structure. the force of each axis in good condition, so that it can reduce the gear, shaft and bearing wear, extending the life of multi-axis head. In addition, we carried out a detailed parts of the transmission parameters and structure design, and on the transmission parts for checking the strength and stiffness, to achieve design accurac
