微型轴承外表面缺陷自动检测线设计 机械学院140108班 史永杰摘要目前我国大部分轴承产品加工企业，特别是一些中小规模的生产单位，对产品感官指标的检测还要借助于人的视觉和个人主观判断能力,因而占用了大量的人力,而且由于受到个人的视力、情绪、疲劳、光线等因素的影响,工作效率低,分选差异大。如何提高检测效率、检测的准确度，成为一个重要的研究课题。本次设计引入了一个新的现代化的检测技术：基于图像识别技术的在线检测。本次我的任务主要是设计整个检测线以及与其配套的相关执行系统、及相关软件。设计出了以同步带为传送方式的轴承输送带，设计出了4轴机械手，及其控制电器图，并编制了以部分系统软件。 经过设计，证明基于机器视觉的轴承在线检测系统的开发完确是可行的，我们的设计完全可以用到轴承生产企业中去。关键字：图像识别；在线检测；同步带；机械手Abstract Currently ，most of bearings production enterprises of our country , especially some factories of medium and small scale, still need to ask for help from the persons sense of vision and personal subjective judgment abilities to the examination of the product sense organs index sign, as result of taking up a great deal of manpower, and because of being affect by the factors, such as personal sight, motion, fatigue and ray.etc., the work efficiency is low, and the difference of choosing is obvious. How to raise the degree of the efficiency and accurate examination, becomes an important research topic.This design led to go into a new modernized of examination technique: on-line examination based on image understanding technique. My mission mainly is to design the whole examination line performance system, and software with its kit of related. We have designed bearings belt taking synchronously belt as the conveying way, 4 stalk mechanical hands, and electric appliances controlling diagram, also we have drawn up parts of system software. Through designing, it shows that the development of bearings on-line examination system is reasonable; Our design can used in the manufactures of bearings production.Keywords: image understanding; on-line examination; synchronously belt; manipulator目录第一章 概 述 11.1 前 言 11.2 国内外发展情况11.3 课题研究内容1第二章 系统总体设计32.1系统总体技术分析 32.2总体系统工作原理 22.3系统描述及关键问题分析 42.4系统总体的组成 52.5 总体系统的设计任务 6第三章 输送线的设计 73.1 自动线的设计选用要点 73.2 同步带简介 73.3 同步带的设计计算 10第四章 机械手的设计 164.1引言164.2 机械手的组成 164.3 机械手的整体功能 174.4机械手手部得设计 194.5 臂部设计 204.6 机身设计 214.7 底座设计 244.8 滚动轴承的选择计算 274.9 联轴器的选择 274.10 机械手的基本参数28第五章 中间轴轴径估计295.1 初估轴径 295.2 零件的强度校核 30第六章
