题目: 数控XY工作台与控制系统设计
摘要
数控机床是一种高精度、高效率的自动化机床。能够适应市场对产品多样化、高精度和快速响应的加工要求,因此得到了广泛的应用。数控机床正朝着高性能、高智能化、系统化以及轻量、微型化方向发展。作为一个较完善的机电一体化系统,数控车床应包含以下几个基本要素:机械本体、动力与驱动部分、执行机构、传感测试部分、控制系统及信息处理部分。
XY数控工作台采用开环控制系统,结构简单、实行方便并且能够保证一定的精度,设计主要对工作台的机械部分进行设计,包括滚珠丝杆、滚动导轨、轴承等传动元件及步进电动机的计算及选用,最后对控制系统进行了分析和完成各电子元件的选用,并且利用CAD进行了装配图的绘制,各机械元件的设计及各零件的安装也做了比较详细的说明。
关键词: 数控车床机械部分传动元件控制系统
Abstract
XY table of C machine tool and control system design.
C lathe is a high -efficiency automatic machine. Can able to adapt to the market what product diversification. the processing requirements of high accuracy and fast response. has been widely used. CNC lathe is moving high-performance. high intelligence. Organization. and lightweight. miniaturized direction. As a plete mechatronic systems , CNC lathes should contain the following basic elements: mechanical body . part of the motivation and drive. executing agency . the sensor test section .the control system and information processing section .
C table using open-loop control simple structure. convenient to implement. And be able to guarantee a certain accuracy. This design is mainly designed for the mechanical part of the workbench. Including ball screw. rolling guide bearings . stepper motor and other transmission elements calculation and selection. Finally, the analysis to control system plete selection of ponents. In the same time. Use software CAD drawing of the assembly drawing. The design of ponents and parts installed a more detailed explanation
Key words: CNC lathes. mechanical part. driving element. control system
