PAGE 2 数控机床分度工作台设计 摘要 本论文对数控机床分度工作台进行了设计，通过研究分度工作台的基本原理，结合数控、液压驱动、齿轮传动等知识，设计出一种运用于加工中心的数控机床分度工作台。为了提高工作台的分度精度，本设计采用了多弹性齿减小累积误差的原理，设计出半弹性齿的工作台分度装置。这种弹性齿分度精度高、制造成本低、经济效益好，今后将会在数控机床上得到广泛的应用。 关键词：分度工作台；数控；液压；齿轮；弹性齿 The design of hydraulic CNC indexing workbench Abstract This paper design on the work bench of CNC indexing，it will design a kind of application to the hydraulic CNC dividing workbench through the research on the basic principle of the indexing of workbench, combined with the knowledge of CNC, hydraulic drive of, and gear transmission, and so on. In order to improve the precision and indexing of the workbench, this design makes use of the principle of elastic gear to reducing error and it will design a half elastic indexing equipment of workbench。The cost of this elastic gear is low and the efficiency of the economy is good as well as the indexing and precision, which will apply widely on CNC lathe in the future. Keywords: indexing workbench, CNC, Hydraulic, Gear, Elastic gear 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc262591034 1绪论 PAGEREF _Toc262591034 \h 1 HYPERLINK \l _Toc262591035 1.1前言 PAGEREF _Toc262591035 \h 1 HYPERLINK \l _Toc262591036 1.2数控机床的发展现状和趋势 PAGEREF _Toc262591036 \h 2 HYPERLINK \l _Toc262591037 1.2.1我国数控机床的发展现状 PAGEREF _Toc262591037 \h 2 HYPERLINK \l _Toc262591038 1.2.2数控机床的发展趋势 PAGEREF _Toc262591038 \h 3 HYPERLINK \l _Toc262591039 1.3数控工作台的研究 PAGEREF _Toc262591039 \h 3 HYPERLINK \l _Toc262591040 1.4数控工作台分度头的研究 PAGEREF _Toc262591040 \h 4 HYPERLINK \l _Toc262591041 1.5本课题研究的内容 PAGEREF _Toc262591041 \h 5 HYPERLINK \l _Toc262591042 2数控机床分度工作台总体方案设计 PAGEREF _Toc262591042 \h 6 HYPERLINK \l _Toc262591043 2.1数控机床分度工作台原理设计 PAGEREF _Toc262591043 \h 6 HYPERLINK \l _Toc262591044 2.2数控机床分度工作台的主要技术参数 PAGEREF _Toc262591044 \h 8 HYPERLINK \l _Toc262591045 2.3数控机床分度工作台的液压系统设计 PAGEREF _Toc262591045 \h 8 HYPERLINK \l _Toc262591046 2.3.1液压系统的方案设计 PAGEREF _Toc262591046 \h 8 HYPERLINK \l _Toc262591047 2.3.2液压泵的选择 PAGEREF _Toc2625
