摘要

 
我的设计题目是惰齿轮轴钻孔夹具设计。我设计的夹具要应用于钻床上，完成对轴类零件的定位，使得对该轴的钻的孔的尺寸要求和位置要求都要达到设计要求。我从对夹具体的外形选择、定位元件的选择、加紧方式的选择分析出发，对惰齿轮夹具进行设计。我的夹具体选择半开式夹具体，便于工件的放入和取出，以便减少加工程序的繁冗而提高加工加工效率；我选择的定位元件是可调节的支撑钉和V形块，用于限制需要限制的自由度；我选择的夹紧方式是螺旋手柄推动另一个可以移动的V形块来达到夹紧工件的目的。在完成对夹具的设计后，我还对夹具的定位误差加以校核，以保证夹具的定位要求可以达到设计要求。
我的设计说明书包含的内容有封面、中英文摘要、目录、正文、参考文献、和致谢这些部分。
最后由于本人知识有限、经验不足，这份毕业设计肯定还存在很多技术上的问题，衷心希望各位老师和同学批评指正。

    My graduation project entitled idler gear shaft drilling fixture design. Fixture designed to be used in a drilling machine, complete the positioning of the shaft parts, making the axis of the drill hole size requirements and location requirements must meet the design requirements. From the specific shape on the folder, select the choice of positioning components, to intensify the analysis of mode choice, the idler gear fixture design. Specific folder select semi-open specific folder for easy loading and unloading of the workpiece in order to reduce the burdensome processing procedures to improve processing processing efficiency; I chose the positioning element is adjustable support nails and V-shaped block used to limit the need to limit the degrees of freedom; I chose the clamping spiral handle to promote another can move the V-shaped block to achieve the purpose of clamping the workpiece. In the design of the fixture, I be checking the positioning error of the fixture to fixture positioning requirements can meet the design requirements
My design specification includes the contents of the cover, Chinese and English abstracts, directories, text, references, and thanks
Finally, because of my limited knowledge, lack of experience, this graduation project there sure is a lot of technical issues, and sincerely hope that you teachers and students criticized the correction.
 
Keywords：Drill press fixcure、the support nail、V-shaped block、position error.
