摘 要
此次畢業(yè)設(shè)計(jì)任務(wù)是對(duì)機(jī)油泵端蓋零件的機(jī)械加工工藝、夾具的設(shè)計(jì)。由機(jī)油泵端蓋零件圖可知,它的外表面上有四個(gè)平面需要進(jìn)行加工。兩軸承孔加工。此外各表面上還需加工一系列孔。因此可將其分為三組加工表面。它們相互間有一定的位置要求。在夾具的設(shè)計(jì)過(guò)程中,本夾具主要用來(lái)加工通孔Φ16H7和Φ20H7的鉆擴(kuò)孔。這兩孔與泵蓋面1垂直。因此在本道工序加工時(shí)主要應(yīng)考慮如何提高勞動(dòng)生產(chǎn)率,降低勞動(dòng)強(qiáng)度。
關(guān)鍵詞 機(jī)油泵端蓋零件,加工工藝,夾具設(shè)計(jì)。
ABSTRACT
The graduation design task is to pump end cover parts machining process, fixture design. By the oil pump cover parts diagram shows, on its outer surface has four planar needs for processing. Two bearing hole processing. In addition the surface is also required for processing a series of holes. It can be divided into three groups of machined surface. Among them a certain location requirements. A fixture in the design process, the fixture is mainly used for processing holes of diameter 16H7 and a 20H7 drilling and reaming. The two hole and pump cover 1 vertical. Therefore, in the process processing mainly should consider how to improve labor productivity, reduce labor intensity.
Key words Oil pump cover parts, processing craft, jig design.
