摘 要
本次畢業(yè)設(shè)計(jì)題目是數(shù)控機(jī)床的自動(dòng)排屑裝置設(shè)計(jì)。本人致力于整機(jī)機(jī)械系統(tǒng)的設(shè)計(jì),即包括電動(dòng)機(jī)的選擇,帶傳動(dòng)設(shè)計(jì),減速器的設(shè)計(jì),鏈傳動(dòng)的設(shè)計(jì),排屑裝置外形的設(shè)計(jì)。設(shè)計(jì)思路是從排屑機(jī)的性能和動(dòng)作要求入手,并以國內(nèi)的質(zhì)量和技術(shù)性能接近設(shè)計(jì)要求的排屑機(jī)為基礎(chǔ),研究國外的先進(jìn)機(jī)型,設(shè)計(jì)出市場需求的以經(jīng)濟(jì)為第一設(shè)計(jì)原則的適用于數(shù)控機(jī)床的排屑裝置。圖紙采用Auto CAD 繪制。經(jīng)過認(rèn)真地設(shè)計(jì)計(jì)算,查找資料撰寫設(shè)計(jì)論文。
本文的排屑裝置,它是針對市場的需要而設(shè)計(jì)的,從而能有效地滿足當(dāng)今市場上對排屑裝置的需求,它具有如下的優(yōu)點(diǎn):傳動(dòng)平穩(wěn),傳動(dòng)效率搞,生產(chǎn)效率高,勞動(dòng)強(qiáng)度低,產(chǎn)品質(zhì)量好,經(jīng)濟(jì)性好,人性化等優(yōu)點(diǎn)。

ABSTRACT
My graduation project is the subject of CNC machine tools automatically Paixie design. I am committed 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
