齿轮泵泵体前、后端面铣削专机总体设计

【摘  要】：本次毕业设计是齿轮泵泵体前、后端面铣削专机总体设计。齿轮泵泵体结构复杂，普通机床加工难度大，生产效率低。然而组合机床是以大量的通用部件为基础,配以少量的按被加工零件特殊要求而设计的专用部件,以实现对一种或几种零件按预先确定的工序进行加工的高效机床。它既具有专用机床的结构简单、生产率及自动化程度较高的特点,又具有一定的重新调整能力,以适应工件变化的要求。所以为了提高生产效率，降低劳动强度，专门设计一齿轮泵泵体前、后端面铣削组合机床及其专用夹具。这次设计主要内容：齿轮泵泵体铣削加工工艺规程设计，专用组合机床得设计，机床结构方案与配置形式确定，针对这道工序进行专用夹具得设计以及外文翻译和编辑说明书。

The End-Milling Plane Design Of Gear Pump Body Before And After

【Abstract】：The graduation project is a gear pump body before and after the end-milling plane design. Gear pump body structure of the complex, general machining difficult and low productivity.However The combination of machine tools is a lot of common parts for the foundation, was supported by a small number of special requirements for the processing parts and components for the design, to achieve one or more of the components of the pre-set process for the efficient processing machine. It has a dedicated machine simple structure, productivity and a higher degree of automation features, but also has a re-adjustment ability to adapt to changing requirements of the workpiece. So, in order to improve productivity and reduce labor intensity, specially designed gear pump a pump body before and after the combination of end-milling machine and a dedicated fixture. The main elements of design: gear pump Milling Process pump body design, a special combination of machine tool design, machine tool structure and the configuration form for this process to a dedicated fixture design and foreign language translation and editing of brochures.
