CA6140車床撥叉831008夾具設(shè)計(jì)
摘要
撥叉的加工質(zhì)量將直接影響機(jī)器的性能和使用壽命。本次設(shè)計(jì)旨在提高CA6140車床撥叉的加工效率，由此我們首先對(duì)撥叉的結(jié)構(gòu)特征和工藝進(jìn)行了仔細(xì)的分析，然后確定了一套合理的加工方案，加工方案要求簡(jiǎn)單，操作方便，并能保證零件的加工質(zhì)量。在制定加工工藝規(guī)程的順序如下：
1分析零件；
2選擇毛坯；
3設(shè)計(jì)工藝規(guī)程：包括制定工藝路線，選擇基準(zhǔn)面等；
4工序設(shè)計(jì)：包括選擇機(jī)床，確定加工余量，工序尺寸及毛坯尺寸，確定切削用量及計(jì)算基本工時(shí)等；
5編制工藝文件。
此外，為了提高勞動(dòng)生產(chǎn)率，降低勞動(dòng)強(qiáng)度，保證加工質(zhì)量，需設(shè)計(jì)專用夾具，本次設(shè)計(jì)選擇了第六道工序銑斷雙體的專用夾具設(shè)計(jì)，以滿足加工過(guò)程的需要。

Abstract

Dials the fork processing quality directly will affect the machine the performance and the service life. This design is for the purpose of enhancing the CA6140 Lathe machine Dials the fork the processing efficiency, first has carried on the careful analysis from this us to the Dials the fork structure characteristic and the craft, then had determined set of reasonable processings plans, the processing plan request are simple, the ease of operation, and can guarantee the components the processing quality. In formulation processing technological process order as follows:
1 analysis the components;
2 choices semifinished materials;
3 designs technological process: Including division Craft route, preferred orientation datum and so on;
4 working procedures designs: Including chooses the engine bed, the determination processing remainder, the computation working procedure size and its the Semifinished materials size, the determination cutting specifications and the computation man-hour and so on;
5 establishments technological document.
In addition, in order to enhance the labor productivity, reduces the labor intensity, guaranteed the processing quality, must design the unit clamp, this design chose the six working procedure to The mill breaks Catarmaran Special-purpose jig design, by satisfied the processing process the need.
Key words: Dials the fork; technological process; jig desin。
