Body parts of the main plane of the surface and pore system. In general, the plane guarantee processing precision than that of holes machining precision easy. Therefore, this design follows the surface after the first hole principle. Plane with holes and the processing clearly divided into roughing and finishing stages of holes to ensure machining accuracy. Datum selection box input shaft and the output shaft of the supporting hole as a rough benchmark, with top with two holes as a precision technology reference. Main processes arrangements to support holes for positioning and processing the top plane, and then the top plane and the supporting hole location hole processing technology. In addition to the follow-up processes individual processes are made of the top plane and technological hole location hole and plane processing. Supported hole processing using the method of coordinate boring. The whole process of processing machine combinations were selected. Selection of special fixture fixture, clamping means more choice of pneumatic clamping, clamping reliable, institutions can not be locked, so the production efficiency is high, suitable for large batch, line processing, can meet the design requirements.Key words: Angle gear seat parts; fixture;IV目录摘 要IABSTRACTII第1章 加工工艺规程设计11.1 零件的分析11.1.1 零件的作用11.1.2 零件的工艺分析11.2 带轮加工的主要问题和工艺过程设计所应采取的相应措施21.2.1 孔和平面的加工顺序21.2.2加工方案选择21.3 带轮加工定位基准的选择31.3.1粗基准的选择31.3.2 精基准的选择31.4 带轮加工主要工序安排41.5 机械加工余量、工序尺寸及毛坯尺寸的确定61.6选择加工设备及刀、量具61.7确定切削用量及基本工时（机动时间）7第2章 斜砌滑块式定心夹紧三爪卡盘182.1 车床夹具设计要求说明182.2车床夹具
