1、 I 摘 要 本设计设计题目是花键轴工艺及钻模设计。 轴类零件在机械行业中占有很重要的地位。在原动机大多提供回转运动的 现状下，轴类零件在各类机械设备的设计中使用频率很高。要保证符合要求的 零件质量，除了合理的结构设计以外，在加工中制订并采用合理的加工工艺和 符合精度要求的夹具、辅具同样也必不可少。本课题主要针对一特定航空轴进 行工艺规范的编制和其中2 径向孔钻模夹具的设计。该轴有较为复杂的结构 和精度、技术要求。基本可以囊括一般轴类零件的加工方法和步骤。首先，运 用机械制造技术及相关的课程知识，依据零件和生产纲领的要求，分析从毛坯 到零件整个过程中每一道工序的进行和安排，制定出切实可行的加工

2、工艺规程 路线，确定加工方案。然后，根据图纸要求的技术条件解决工件在加工过程中 的定位、加紧以及工艺路线的安排等方面的相关问题，确定相关的工艺尺寸及 选择合适的机床和刀具。最后，参考机床夹具设计手册及相关方面的书籍，设 计出高效、经济、合理并且能保证加工质量的夹具。 关键词：轴，工艺路线，机械制造，钻床夹具 II ABSTRACT This design topic is the tail spline shaft connecting process and drilling jig design parts. Shaft parts takes a very important posit

3、ion in the machinery industry .Under the condition that the majority of primary motors can only provides the rotary motion. The quality of shafts can largely influents the using conditions and the using life of equipments wherever shafts use .In addition to guarantee the quality of a shaft to plan a

4、 good enough processing and apply the fitful fixture can play the very important role but to do a good structure design.Researching the processing of a particular air shaft and the design of the 2 radial hole content the most of this paper .The shaft has the mid-complex structure and accuracy demand

5、 .First,using of machinery manufacturing technology and related knowledge, on the basis of parts and the requirements of the production program, analysis from the blank to the whole process of parts of every process and arrangement, formulate the processing procedure of feasible routes, determine th

6、e processing scheme. Then, according to the technical condition requirements of the drawings, the workpiece in the process to solve relevant problems in stepping up and aspects of the process route arrangement, determine the relevant process size and select the appropriate machine tools and tool. Finally, machine tool fixture design reference manual and related aspects of the books, the design of efficient, economic, reasonable and can ensure the quality of processing fixture. KEY WORDS: shaft
