Abstract

 This text introduce R180 diesel engine crankshaft technological design and two of them jig of process design mainly. The author of this text is guaranteeing product quality, boost productivity, lower costs, utilize existing working condition, guaranteeing worker to have good work prerequisite of terms to design . In technological design, the author combine carrying on theory design, improve the traditional production technology of the crankshaft actually, optimize craft course and craft equip, enable economy rational even more of production and processing of the crankshaft. Designing in the jig , the author collect the relevant materials, such as lathe, cutter and handling tool，etc. At the foundation of the analyse of work piece material, specification requirement and craft, and make jig of request according to jig measure design and cankshaft production technology and jig.
