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。
