CA6140車床輸出軸工藝設(shè)計(jì)


摘　要

這次設(shè)計(jì)的是CA6140車床輸出軸2*Φ8斜孔，包括被加工工件的零件圖、工件的毛坯圖、夾具裝配圖、夾具體圖各一張，機(jī)械加工工藝過程卡片和與工序卡片各一張。輸出軸作為動(dòng)力裝置的主要零件，工藝工裝的設(shè)計(jì)與改良直接影響著其質(zhì)量與性能。

本文首先介紹了輸出軸的作用和工藝分析.然后，根據(jù)零件的性質(zhì)和零件圖上各端面的粗糙度確定毛坯的尺寸和械加工余量。最后擬定鉆孔的工藝路線圖，制定該工件的夾緊方案，畫出夾具裝配圖。

本次課程設(shè)計(jì)主要是應(yīng)用機(jī)械制造技術(shù)，是一次深入的綜合性的總復(fù)習(xí)。通過這次課程設(shè)計(jì)，了解并認(rèn)識(shí)一般機(jī)器零件的生產(chǎn)工藝過程，鞏固和加深已學(xué)過的技術(shù)基礎(chǔ)課和專業(yè)課的知識(shí)，理論聯(lián)系實(shí)際，從中鍛煉自己分析問題、解決問題的能力，為今后的工作打下一個(gè)良好的基礎(chǔ)，并且為后續(xù)課程的學(xué)習(xí)打好基礎(chǔ)。


 


 


Abstract

Designing that this time is that the CA6140 lathe exports 2*Φ8 holes. The part including the workpiece being processed pursues , the workpiece blank pursues , clamp assembling picture , the clip pursue concretely every sheet, the machine work procedure card draws and the working procedure card takes a look respectively once. The part , handicraft frock design and reform exporting axis main part as the power set are having direct impact to whose mass and function.

The effect and handicraft having introduced the axis outputing's first analyse the main body of a book. And then, the dimension and instrument having pursued every end face harshness according to part character and part ascertain a blank process a margin. The at last designs the handicraft route chart drilling , works out the fastening motion scheme being workpiece's turn , draws up clamp assembling picture.

Time of curriculum design is the general review applying the machinofacture technology , being a thorough comprehensiveness originally mainly. By current curriculum design, process knowing and knowing general machine part productive technology, the knowledge consolidating and deepening the technology basic course and specialized course have already learned, integrates theory with practice. Temper self analytical problem , the ability to solve problems out of , be that job the days to come lays down one is fine basis, and be that follow-up course study about finishes striking a basis.
