Abstract
Making the processing technology of lathe I axis, designing the drilling fixture for drilling hole 23, using the basic theory in the course of mechanical manufacturing technology and the practical knowledge learned in the production practice, correctly solving the problems of positioning, clamping, process route arrangement and process dimension determination of a part in the processing, so as to ensure the processing quality of the parts. Improve the ability of structural design. Through the training of fixture design, the ability of fixture designwhich is efficient, labor-saving, economical and reasonable and can guarantee the processing quality is obtained according to the processing requirements of the processed parts. Learn to use manuals and charts. Master the name and source of all kinds of data related to this design, and be able to use it skillfully. Graduation design is a thorough and comprehensive summary ofwhatwe have learned and a training of integrating theorywith practice. Therefore, it occupies an important position in our college life. In addition, after completing this graduation project, I got a comprehensive training, I think I can get exercise in many aspects. Personally, I hope that through this graduation project, Iwill carry out an adaptability training for my futurework, fromwhich I can exercise my ability to find, analyze and solve problems, and lay a good foundation for future participation in the construction of the motherland.
