齒輪泵泵體前、后端面銑削專機總體設(shè)計

【摘  要】：本次畢業(yè)設(shè)計是齒輪泵泵體前、后端面銑削專機總體設(shè)計。齒輪泵泵體結(jié)構(gòu)復(fù)雜，普通機床加工難度大，生產(chǎn)效率低。然而組合機床是以大量的通用部件為基礎(chǔ),配以少量的按被加工零件特殊要求而設(shè)計的專用部件,以實現(xiàn)對一種或幾種零件按預(yù)先確定的工序進行加工的高效機床。它既具有專用機床的結(jié)構(gòu)簡單、生產(chǎn)率及自動化程度較高的特點,又具有一定的重新調(diào)整能力,以適應(yīng)工件變化的要求。所以為了提高生產(chǎn)效率，降低勞動強度，專門設(shè)計一齒輪泵泵體前、后端面銑削組合機床及其專用夾具。這次設(shè)計主要內(nèi)容：齒輪泵泵體銑削加工工藝規(guī)程設(shè)計，專用組合機床得設(shè)計，機床結(jié)構(gòu)方案與配置形式確定，針對這道工序進行專用夾具得設(shè)計以及外文翻譯和編輯說明書。

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.
