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: pump parts; fixture;IIIIV目 錄摘 要IIABSTRACTIII第1章 加工工藝規(guī)程設(shè)計(jì)11.1 零件的分析11.1.1 零件的作用11.1.2 零件的工藝分析21.2 總泵缸體加工的主要問題和工藝過程設(shè)計(jì)所應(yīng)采取的相應(yīng)措施21.2.1 孔和平面的加工順序21.2.2加工方案選擇21.3 總泵缸體加工定位基準(zhǔn)的選擇31.3.1 粗基準(zhǔn)的選擇31.3.2 精基準(zhǔn)的選擇31.4 總泵缸體加工主要工序安排41.5 機(jī)械加工余量、工序尺寸及毛坯尺寸的確定61.6確定切削用量及基本工時（機(jī)動時間）71.7 時間定額計(jì)算及生產(chǎn)安排17第2章 銑右端面夾具設(shè)計(jì)192.1設(shè)計(jì)要求192.2夾具設(shè)計(jì)192.2.1 定位基準(zhǔn)的選擇192.2.2 切削力及夾緊力的計(jì)算192.3定位誤差的分析253.5 確定夾具體結(jié)構(gòu)和總體結(jié)構(gòu)262.4夾具設(shè)計(jì)及操作的簡要說明27結(jié) 論28參考文獻(xiàn)29致 謝3143
