摘　要
工艺规程是工装设计、制造和确定零件加工方法与加工路线的主要依据，它对组织生产、保证产品质量、提高劳动生产率、降低成本、缩短生产周期及改善劳动条件等都有着直接的影响，因此是生产中的关键工作。夹具在机械加工中起着重要的作用，它直接影响着机械加工的质量，生产效率和成本，因此，夹具设计是机械工艺准备和施工中的一项重要工作。本文对转速器盘的结构和工艺进行了分析，确定了机械加工工艺路线，制订出了零件的铸造工艺方案和机械加工工艺规程，并为加工零件上直径Φ9H8mm的孔设计了一套专用钻床夹具。

Abstract
The process is the base of frock design、manufacturing、the method of machining and machining route. Its function is flowing: organizing produce, controlling quality, enhancing productivity, reducing cost, reducing produce periods, improving work conditions, etc. So, the process planning is the core part of produce. Fixture is very important equipment in process of machine manufacturing because it can directly affect the quality of products and productivity and cost. So fixture designing is also a basilica portion in machine process preparative and manufacture. This thesis is about the analysis with the craftwork and the structure of the speed governor tray which is used for the diesel engine, make sure the process route, establish the foundry process project and the process planning of the parts, and design a set of appropriative fixture for the bore with diameter 9mm.
Key Words：Group technology;  Foundry technology;  Process planning; Fixture design
