According to the plan and didactical brief made by machine manufacturing craft profession committee,this design have mainly compiled and designed teachining technics regulations and appropriative clamp using professional theory and practical knowledge.This design is not only a great chanllenge,but also a good exercise for our graduate.It has enhanced our lever of speciality,at the same time,it also has cultived our team sprint. The design mainly introduces the spare parts craft process,tongs technological design to make comparison system,analysis and argumen integrity.Design craft regulations to make expation,and establishment reasonable of process craft route.In this design,I have analysed and calculated some key working proces,which include the remaining quantity of process,the measure of working procedure procedure the tolerance of working procedure techics cards.Whatmore in the end ,I have designed a appropriative clamp and proof-tested its precision to ensure the quality of workpiece.
