The graduation design topic is formulating S195 diesel engine connecting parts manufacturing procedure and boring head hole fixture design, want to reduce production cost in the also can produce good quality products at least, the process of manufacturing and processing time meet the shape, size, accuracy and surface roughness and requirements of the product. Design should guarantee the machining accuracy of workpiece loading and unloading, and use of reasonable fixture structure, and has certain practical value. Due to the theoretical knowledge and practical experience. I will consider using universal stronger processing method, but the machining procedure can appropriate USES advanced manufacturing technology and special machine equipment, tools and measuring tool. The main content of this project is to analyze the technical conditions of the parts and painted parts blank. The plan was reasonable process route, big hole clamp sketches and boring fixture. This design USES the connecting rod body and connecting separated, and formulate relative reasonable forging process. In part, the size of fixture design with head big hole hole surface, small head for convex and locating datum, and achieve the goal orientation positioning principle, clamping mechanism using spiral clamping institutions, i.e. reached clamping effect.
