铣床主轴的加工工艺及铣2-8H9键槽夹具设计
摘要
本次设计的题目是基于三维软件的铣床主轴的加工工艺及铣2-8H9键槽夹具设计，根据图纸要求进行机械工艺规程设计和专用铣床夹具设计，在掌握零件作用的基础上，对零件的工艺进行分析。
针对设计给定的题目，设计出铣削2-8H9键槽的专用铣床夹具。里面的知识点主要有对机床夹具进行设计、公差等。先对需要加工的零部件进行了解，分析，以便更加精确的对其进行加工，确定加工零件的标准；然后对每一个步进行计算，要算出每一道工序的切削用量；夹具设计包括：设计出对零件进行定位，夹紧，还有引导的各个元件。在这里尤其要注意的是，夹具在定位零部件的时候，会产生误差，这个误差要在的合理控制范围以内，要充分了解夹具的优缺点，以便改进。最后通过PROE软件对夹具完成三维建模。
通过上面的设计、分析和计算，圆满的完成了本次设计的所有任务，在巩固大学所学知识的同时，还为自己步入社会夯实基矗

ABSTRACT
The graduation project is based on the three-dimensional software milling machine spindle machining process and milling 2-8H9 keyway fixture design, according to the requirements of the drawings of the mechanical process design and special milling machine fixture design, in the grasp of the role of parts on the basis of parts Process analysis.
For the given design of the subject, designed to milling 2-8H9 key slot of the special milling machine fixture. The knowledge points inside the paper are mainly designed for the fixture, tolerance and so on. The parts need to be processed to understand and analyze, in order to more precisely its processing, to determine the standard parts processing; and then for each step to calculate the calculation of each process to calculate the amount; fixture design includes: design The positioning of parts, clamping, aswell as thevarious components of the guide. In particular here to note that the fixture in the positioning of parts, itwill produce errors, the errorwithin the reasonable control range, to fully understand the advantages and disadvantages of fixtures in order to improve. Finally, through the PROE software to complete the three-dimensional modeling fixture.
Through the above design, analysis and calculation, the successful completion of the graduation design of all the tasks in the consolidation of the University of knowledge at the same time, but also for their own social solid foundation.
Keywords: Milling machine spindle, processing technology, 2-8H9 keyway, milling machine, PROE
