文档介绍：齿轮油泵零件右端盖的设计第一部分摘要此设计当中包含了机械设计,机械制图,数控加工工艺和数控编程夹具设计等基本知识。在此我以齿轮油泵零件的右端盖为研究对象,通过深入的构思和多次的查阅资料, 设计出合理的工艺装备及编制出合理的加工工艺和程序。学会用理性思维发现问题,处理问题,并解决问题。以达到最终实际目的,使自己的理论知识与实际知识更好的融合在一起。 1、齿轮油泵右端盖的功用和结构特点齿轮油泵右端盖是齿轮油泵的基础零件之一,用手将一些轴套和齿轮等零件组装在一起,使其保持正确的相互位置,并按照一定的传动关系协调的运动。组装后的齿轮油泵,用端盖的基准平面安装在机器上。因此,齿轮右端盖的加工质量对箱体部件装配后的精度有着决定性的影响。且其属于剖分式箱体,结构特点为:结构形状稍微复杂,内部呈空腔,箱壁较厚且不均匀, 其上有许多精度要求很高的轴承孔和装配用的基准平面。此外,还有一些精度要求不高的紧固孔和次要平面。因此,齿轮油泵右端盖要加工部位较多,加工难度也较大。 2、齿轮油泵右端盖的材料和毛坯齿轮油泵右端盖采用灰铸铁 HT200 ,它是有容易变形,吸振性好,耐磨性及切削性好等特点。当生产批量不大时齿轮油泵右端盖毛坯采用木模手工造型,制作简单但毛坯精度较低,余量也较大,大批、大量生产时则采用金属模机器造型。毛坯精度高,余量可适当减少。在单件生产时,有时采用焊接件作毛坯,以缩减短生产周期。摘要写清当今制造业的特点,研究的内容及重要性,以及达到的目的关键词数控编程、加工工艺、铣削加工、齿轮油泵右端盖、装夹方案齿轮油泵零件右端盖的设计 Abstract This design which includes mechanical design, mechanical drawing, digital processing technology and design of numerical control programming, such as basic knowledge of the fixture. I gear pumps in order to cover parts of the right to study, through in-depth access toa number of ideas and information, design and reasonable process and the preparation of equipment ata reasonable level of processing technology and procedures. Institute found that the problem with rational thinking to deal with the problem and solve the problem. In order to achieve the ultimate objective of practical, so that their theoretical knowledge with practical knowledge and better together. 1. cover the right gear pump function and structure of the characteristics of the Gear pump cover is the right gear pumps on the basis ofone of the parts, some with their hands and sleeve assembly of parts such as gears together to keep each other in the right position, and in accordance with the transmission ofa certain relationship between the co-ordination of movement. After the assembly of gear pumps, cover with the base machine installed in the plane. As a result, the right gear on the cover of the processing quality of the after the assembly of ponents have a decisive impact. And his belong to Split, structural charact
