职业技术学院 毕业设计说明书 题 目 T68型卧式镗床电气线路的设计 院 系： 专 业： 机电一体化技术 班 级： 机电13301 学生姓名： 学 号： 201303030111 同组学生： 指导教师： 李 新 平 企业指导教师： 周 建 伟 完成日期： 2016 年 5 月 20 日 摘要 镗床是一种精密加工机床，主要用于孔和孔间距离要求较为精确的零件的加工。按不同用途，镗床可分为卧式镗床、立式镗床、坐标镗床和专用镗床等。在生产中使用较广泛的有卧式镗床和坐标镗床，其中坐标镗床加工精度很高，适合于加工高精度坐标孔距的多孔零件；而卧式镗床具有万能性特点，它不但能完成孔加工，而且还能完成车削端面及内外圆，铣削平面等。本毕业设计进行了T68卧式镗床的主电路及其控制电路的设计，并对其常见故障进行了分析。 【关键词】： T68卧式镗床 、 电气控制电路、 故障分析 Abstract and boring machine is a precision machine, mainly used for processing precise holes and distances between holes require precise parts. According to their different uses, boring can be divided into horizontal boring machines, vertical boring machines, jig boring machine and a dedicated boring machine. More widely used in the production of horizontal boring machine and jig boring machine, jig boring machine accuracy is high, suitable for machining of high-precision coordinate-space of porous parts and horizontal boring machine has universal characteristics, it can not only complete machining, but also complete turning face and internal and external circular, milling, and so on. Here the T68 boring main circuit and control circuit design, and common fault analysis. [Keywords]: T68 boring machine 、circuit design、common analysis. 目 录 概述·····················································1 1-1 T68卧式镗床结构··········································1 1-2 T68卧式镗床性能特点······································2 第二章 T68卧式镗床电气控制系统的设计························4 元器件的选择·············································4 T68卧式镗床主电路设计···································4 T68卧式镗床控制
