KST1002换挡拨叉的加工工艺及铣Φ10上端面夹具设计
摘要
这次设计的主要内容是KST1002换挡拨叉的加工工艺及铣Φ10上端面夹具设计,通过对任务书的解读,内容有加工工艺规程,专用铣床夹具。在掌握零件作用以及对其进行分析的基础上,完成了这2点设计内容。
设计之初通过资料的查阅了解和掌握机床夹具的相关知识,为后面的设计和计算提供保障。说明书里面的知识点主要有对机床夹具进行设计、公差等。首先搞清楚这个加工的零部件,然后对它进行了分析,这样就可以在加工的时候精确度更高,将零件的标准定下来,之后在算一下每一个步骤的切削用量的大小;夹具设计包括:定位零部件,夹紧零部件,另外还有进行引导的哪些零部件。在这还要特别关注的是,在对零部件进行定位的时候,必然会有偏差出现,这个偏差一定要在规定的范围里面,这样才可以对这个夹具的好处,坏处进行了解,对它进行改善。
通过上面的设计、分析和计算,圆满的完成了本次课程设计的所有任务,在巩固之前所学知识的同时,还为今后的学习夯实基矗

Abstract
The main content of this design is the processing technology of KST1002 shifting fork and the design of the upper end fixture of milling_10. Through the interpretation of the task book, the contents of the processing procedures, special milling machine fixture. On the basis of mastering the function of parts and analyzing them, the 2 points are completed.
At the beginning of the design, through the consulting of information to understand and master the relevant knowledge of machine tools and fixtures, to provide support for the later design and calculation. The knowledge points in the manual mainly include the design and tolerance of machine tools and fixtures. Firstly, make sure of the parts, then analyze them, so that they can be more accurate in processing, set the standard of the parts, then calculate the cutting parameters of each step; fixture design includes: positioning parts, clamping parts, and other guiding parts. Which parts? In this particular concern is that in the positioning of parts, therewill inevitably be a deviation, the deviation must bewithin the prescribed scope, so that the advantages and disadvantages of this fixture can be understood, to improve it.
Through the above design, analysis and calculation,we have successfully completed all the tasks of this course design. While consolidating the previous knowledge,we also lay a solid foundation for future learning.
