齿轮油泵零件右端盖的加工工艺摘要首先,本人设计齿轮油泵零件右端盖的机械加工工艺规程及工艺装备,不过本人对于自己设计的齿轮油泵右端盖经过了解,根据零件的形状、尺寸精度、生产的经济效益等各方面的详细分析其加工工艺,采用多工序,数控机床加工。
通过对零件的分析,此齿轮油泵右端盖要求精度高,工序适当集中,要求光滑,所以选用的工具和尺寸要量得准。
最后对零件进行校核。
以便达到零件精度的要求。
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。
随着科学技术的进步,各种新技术、新工艺、新材料和新设备不断涌现,机械制造工艺正向着高质量、高生产率和低成本方向发展。
所以我们必须捉住机遇,把引进国内外先进技术(如数控设备)和自己的研究创新结合起来,奋发图强,加快发展速度,为使我们厂生产出一批具有世界先进水平的产品,提高我们厂的生产。

Through parts of the analysis, the right gear pumps cover the requirements of high precision, the appropriate processes focused on demanding smooth, so the selection of tools and size to the amount accurately. Finally, check for components. In order to meet the requirements of precision parts. ,( cover the right gear pump function and structure of the characteristics of theGear pump cover is the right gear pumps on the basis of one 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 of a 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 thecover of the processing quality of the cabinet after the assembly of precision components have a decisive impact.And his cabinet belong to Split, structural characteristics: the structure of the shape of a little complex, was an internal cavity,thick-walled box and uneven, and its many high precision bearings usedin the assembly hole and the base plane. In addition, there are a number of less demanding precision fastening holes and secondary plane. As a result, gear pumps right to cover large parts of the processing, processing more difficult.,( gear pumps cover the right materials and roughGear pumps use the right cover gray cast iron HT200, it is easy to deformation, vibration absorber of good wear resistance and good cutting and so on. When the production volume is not right when the oil pump gear cover rough shape by hand using wooden mold, but the simple production of rough lower accuracy, is also a greater margin, a large number, when mass-produced metal mold machine model. Blank and high precision, to reduce the margin may be appropriate. In the production of one-piece, sometimes used for welding pieces of rough, so as to reduce the short production cycleWith the progress in science and technology, a variety of new technologies, new materials and new equipment have emerged, machinery manufacturing is toward high-quality, high productivity and low-cost direction. That is why we must seize the opportunity to introduce advanced technology at home and abroad (such as numerical controlequipment) and its innovative combination of research, work hard to accelerate the pace of development, we plant to produce a number of world-class products, improve our Factory production齿轮油泵零件右端盖的加工工艺Key words:NC programming, processing,milling, gear pumps right end caps,clamping p前言21世纪机械制造业的竞争,其实质是数控技术的竞争,这种竞争是全方位的。
