The design of Block entitled rocker shaft technology and equipment design and CAD / CAM. From Chaoyang Diesel Engine Company is designed to complete the 195-seat rocker shaft diesel engine mold design, Rocker Shaft Tower card processing routes and the development process, some special fixture design modeling software Pro / E into the mold of its design, including: the construction of a module with parts and blank parts of the solid model; on the part of the investment casting mold design, including sub-surface, injection system, pushing pieces of bodies, punch and die, mold base, etc., with engineering drawings and CAXA electronic board module to complete the mold assembly drawings. Order to develop machining technology, including process selection, process development line, the determination of machining allowance, and then calculated according to the technical point of order parameters and the appropriate technology to produce the card. Special milling fixture design, 2 sets of special drilling jig 1 set: the analysis, selection and design, the use of CAXA electronic drawing board to complete its work design of the difficulties is the fixture and die, in the access to a wealth of information and very good teachers under the guidance of the final settlement of these issues, the successful completion of the design.
