The main processing surface of vane pump pump body parts of the right end face and a series of hole. In general, to ensure the processing accuracy of plane than to guarantee the machining accuracy of the series of hole. Therefore, the design follows the principle of the surface after the first hole. And the hole and the plane processing clearly divided into rough machining stage and finish machining stage in order to guarantee the working accuracy of the series of hole. Choose special fixture fixture clamping way choose manual clamping, clamping reliable, agencies can not self-locking. Therefore the production efficiency is higher. Suitable for large batch processing, assembly line. To meet the design requirements.Keywords: vane pump right pump body parts; technology; fixture; PAGE VI目 录 TOC \o 1-3 \u 摘 要 PAGEREF _Toc416628712 \h IIABSTRACT PAGEREF _Toc416628713 \h III第1章 绪论 PAGEREF _Toc416628714 \h 11.1 机械加工工艺概述 PAGEREF _Toc416628715 \h 11.2机械加工工艺流程 PAGEREF _Toc416628716 \h 11.3夹具概述 PAGEREF _Toc416628717 \h 21.4机床夹具的功能 PAGEREF _Toc416628718 \h 21.5机床夹具的发展趋势 PAGEREF _Toc416628719 \h 31.5.1机床夹具的现状 PAGEREF _Toc416628720 \h 31.5.2现代机床夹具的发展方向 PAGEREF _Toc416628721 \h 4第2章 加工工艺规程设计 PAGEREF _Toc416628722 \h 62.1 零件的分析 PAGEREF _Toc416628723 \h 62.1.1 零件的作用 PAGEREF _Toc416628724 \h 62.1.2 零件的工艺分析 PAGEREF _Toc416628725 \h 62.2 叶片泵右泵体加工的主要问题和工艺过程设计所应采取的相应措施 PAGEREF _Toc416628726 \h 72.2.1 孔和平面的加工顺序 PAGEREF _Toc416628727 \h 72.2.2加工方案选择 PAGEREF _Toc416628728
