1、数显数显水平转台设计水平转台设计 院院 系系 机械工程学院机械工程学院 专业专业 机械电子工程 STUDY ON DIGITAL DOUBLE-AXIS EXACT GRADIENT REVOLVING TABLE 中中文文文文摘摘 ：由于电子技术的飞速发展和国防、工业生产等领域的需要，高精度高自动化的 数控加工设备越来越受到重视， 而转台作数控加工的关键设备已经被广泛的用于航空、 航天、 国防及工业生产等领域。本课题以“数显水平转台”为研究背景，主要对水平转台整体系统进 行了结构设计、控制系统设计及测角系统和角位移显示的设计与研究。 本文首先进行了结构总体设计，包括竖直轴 360o 回转的实

2、现，快速定位和锁紧机构的 设计， 其中， 定位加紧机构的设计和选择一种能提高回转精度的传动方案是这次设计的重点， 本文对其进行了详细的分析和设计。之后，文中对转台控制进行了较详细的设计。 在角位置测量系统设计中， 选用圆光栅直接对工作台的角位移进行测量， 并对测量数据 进行反馈，通过六位数码显示对测量值进行输出显示。 中文关键词中文关键词结构设计；定位夹紧机构设计；角位置测量 英文文英文文摘摘 ：As a result of electronic technology rapid development and domain and so on national defense, indust

3、rial production need, The high accuracy high automation numerical control processing equipment more and more receives takes, But the turnplate made the numerical control processing the essential equipment already widespread to use in domains and so on aviation, astronautics, national defense and ind

4、ustrial production.This topic360;reveals the horizontal turnplate take the number as the research background, mainly has carried on the design and the research to the horizontal turnplate integrated system which the structural design, the control system design and the goniometrical system and the an

5、gular displacement demonstrated. This article has first carried on the structure system design, including the vertical stroke straight axle 360o rotation realization, the fast localization and the lock mechanism design, among, the localization step-up organization design and chose one kind to be abl

6、e to increase the rotation precision the transmission plan is this design key point, this article has carried on the detailed analysis and the design to it.Afterwards, in the article has carried on the detailed design to the turnplate control. In the angular position measurement system design, selects the round diffraction grating directly to carry on the survey to the work table angular displacement, and carries on the feedback to the survey data, through six numerical codes demonstrated carr
