The mechanical manufacturing industry is one of pillar industrieswhich a country technology advancement and the society develops,regardless of is the traditional industry, or the emerging industry,all cannot leave all kinds of mechanical device. But each kind ofmachine spare part processing core question is a craft. Thisgraduation project was has chosen this kind of topic - conducts theresearch to the power output shaft numerical control processing craftand the slanting hole jig design. In the machining craft establishmentaspect, mainly through the careful analysis product detail drawing andthe related specification, consults the box body class componentscorrelation data, the union summer vacation practises experience andso on, had considered craft structure request, batch request,efficiency, feasible and so on various factor, finally arranged 19working procedures to complete the gear box body the processing,including each working procedure processing method, engine bed,cutting tool, jig, auxiliary, measuring instrument choice, reducedplane selection, located and clamps the plan drawing up, and throughrepeatedly deliberated, the comparison, finally had determined thepreferred plan, and enrolled it the working procedure card, Clearbright expression entire processing process. Moreover, in the jigdesign aspect, mainly drilled slanting Kong Zheige the workingprocedure to carry on the jig plan analysis, the computation andfinally makes a final decision, and expressed the jig plan with anassembly drawing and two detail drawings which designed。
