底座的的钻2-Φ8孔专用夹具设计及机械加工工艺规程含4张CAD图+说明书

底座——A1

摘要
本次设计内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。
底座的机械加工工艺规程及钻、铰2-Φ8孔工序的专用夹具设计。在工艺设计中要首先对零件进行分析，了解零件的工艺再设计出毛坯，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具的设计，对定位方案及元件，夹紧方案及元件进行确定；计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处，并在以后设计中注意改进。

Abstract
This design involves mechanical manufacturing technology and machine tool fixture design, metal cutting machine tools, tolerance coordination and measurement and so on.
The mechanical processing technology of the pedestal and the special fixture design for drilling and hinges 2- 8 hole process. In the process design, the parts are analyzed first, the process of the parts is redesigned and the blank is redesigned. The process datum of the parts is selected and the process route of the parts is designed. Then the size calculation of theworking procedure of the parts is calculated. The key is to determine the equipment and the cutting amount of each process; and then make a special purpose. With the design of the fixture, the positioning scheme and components, the clamping scheme and the components are determined, the positioning error of the fixture positioning is calculated, the rationality and inadequacies of the fixture structure are analyzed, and the improvement is paid attention to in the future design.
Keywords: base; processing technology; fixture design; process route; cutting parameter
