数控机床自动排屑装置设计论文

摘要

本次毕业设计题目是数控机床的自动排屑装置设计。本人致力于整机机械系统的设计，即包括电动机的选择，带传动设计，减速器的设计，链传动的设计，排屑装置外形的设计。设计思路是从排屑机的性能和动作要求入手，并以国内的质量和技术性能接近设计要求的排屑机为基础，研究国外的先进机型，设计出市场需求的以经济为第一设计原则的适用于数控机床的排屑装置。图纸采用Auto CAD 绘制。经过认真地设计计算,查找资料撰写设计论文。

本文的排屑装置,它是针对市场的需要而设计的，从而能有效地满足当今市场上对排屑装置的需求,它具有如下的优点:传动平稳，传动效率搞，生产效率高，劳动强度低，产品质量好，经济性好，人性化等优点。

关键词数控机床，排屑装置，机械系统

ABSTRACT

My graduation project is the subject of CNC machine tools automatically Paixie design. I am 忽略mitted myself to mechanical systems design, including the choice of motor, belt drive design, reducer design, chain drive design. Paixie design ideas from the machine's performance and movements start with requirements and to the quality of domestic and technical performance close to the design requirements of the Paixie based to the advanced foreign models, the development of market demand in the economy as the first design CNC machine tools in the application of the principle of the Paixie devices. Auto CAD drawings by drawing. Through careful design and calculate, designed to find information to write papers.

This paper designed Paixie device, it is against the needs of the market designed so that they could effectively meet the market today Paixie on the demand, it has the following advantages: a smooth transmission, engage in transmission efficiency, productivity, Low labour intensity, product quality, economic, and human advantages

Key words CNC machine tools, Paixie devices, mechanical systems
