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; Process planning; Fixture design目 錄1 零件的工藝分析及生產(chǎn)類型的確定11.1 零件的作用11.2 零件的工藝分析21.3 零件的生產(chǎn)類型22 選擇毛坯、確定毛坯尺寸、繪制毛坯簡圖22.1 毛坯的選擇22.2 確定機械加工余量和公差22.3 設(shè)計及繪制毛坯圖33 選擇加工方法，制定工藝路線33.1 定位基準的選擇33.2 零件表面加工方法的選擇43.3 制訂工藝路線44 工序設(shè)計54.1 9mm孔54.2 確定切削用量及基本工時65 夾具設(shè)計75.1定位方案75.2夾緊機構(gòu)75.3導(dǎo)向裝置85.4夾具體86 方案綜合評價與結(jié)論87體會與展望88參考文獻10
