This design is the eccentric valve, respectively, draw the parts diagram, blank maps, clip a specific diagram, assembly drawing of a mechanical machining process card and with the design of fixture corresponding to those working procedure of the process card each one.Be processed in a familiar body part based on the eccentric. Learn eccentric bodys role, the next according to parts of the nature and parts drawing on each face and the internal structure of the roughness determine the rough size and mechanical machining allowance. Then we re-based positioning base first determine precise benchmark, it became clear that rough benchmark, the finalization of eccentric valve process road map to develop the workpiece clamping program, draw fixture assembly diagram. Through access to a variety of books on the completion of this course design task. 目 录 1、零件的分析…………………………………………………………………………1 1.1零件的作用及特点……………………………………………………………....1 1.2零件的形状......…………
