Grip design has the important effect in machine work , it can swear to process accuracy , to raise product quality , lighten worker's labour intensity , swear to safe , to improve productivity, can use high grade , high-effect, the low consumption handicraft goes to accomplish the part treating and the product assembling. But the benefit having used scale division drill lies in, may adopt multistation treating, the working procedure the energy messenger is processed concentrates, thereby, lighten worker's labour intensity and improve efficacy.Use the basicest clamp purpose to be to gain the good economic effect. Therefore designing that the clamp is also same as other technology job, not only be a technology problem, and be economic problems. Needing to carry out necessary technical economy analysis , make the what be designed that clamp gain optimum economic results before designing a set of clamp everytime. The design constituting a machine tool by the same token is also very important , the science design combination machine tool cuts down on-time and the working strength. The structure the main body of a book is shifted gears fork to change gear carries out industrial analysis , ascertains the route processing handicraft, the call for according to mission book works out out the part technological procedure , design thick bright metal of working procedure III 19 56 and 2.6 44.6 liang of side special use.Keywords Technologicalprocedure Gripdesign Industrial analysis
