摘要

拨叉的加工质量将直接影响机器的性能和使用寿命。本次设计旨在提高CA6140车床拨叉的加工效率，由此我们首先对拨叉的结构特征和工艺进行了仔细的分析，然后确定了一套合理的加工方案，加工方案要求简单，操作方便，并能保证零件的加工质量。在制定加工工艺规程的顺序如下：

1分析零件；

2选择毛坯；

3设计工艺规程：包括制定工艺路线，选择基准面等；

4工序设计：包括选择机床，确定加工余量，工序尺寸及毛坯尺寸，确定切削用量及计算基本工时等；

5编制工艺文件。

此外，为了提高劳动生产率，降低劳动强度，保证加工质量，需设计专用夹具，本次设计选择了第六道工序铣断双体的专用夹具设计，以满足加工过程的需要。

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。
