This graduation design topic is fork and lathe fixture design process .The main design way of thinking BE: the feature of the parts is analyzed so as to plan the reasonable process and select the corresponding machine and jig. Machined parts if they can widely used fixture, you can greatly save the auxiliary time when the processing in order to reduce the amount of labor of workers, improve labor productivity and product quality. Design fixture first general analysis of the raw materials, design requirements and intentions clear, and then propose specific positioning and clamping programs ,. lathe fixture design process .Positioning an article using 5 Morse cone structure to ensure the reliability of the design, but also on the accuracy of the clamp is analyzed.
This graduation design is profession course of theories study and after practice of the last teaching link, pass this design to learn profession course of the theories take in to synthesize and increase produce to practice knowledge, pass by training of machine design, develop and raise thus personal independence work of ability. Make stronger and enlarged the related course contents. Control the method and step of its design. Checked a great deal of machine book in the design, toughen in this process and raised the basic technical ability of machine design, such as calculation, paint, check design data and manual; Acquaint with standard and other of the machine design relevant of standard and norm, and take in to carry through in the design, to after time's work and study beat under solid foundation.
KEY WORDS: Fork , Process planning,Machine tool fixtures
