螺母加工工藝及夾具設(shè)計(jì)【全套設(shè)計(jì)含CAD圖紙】,全套設(shè)計(jì)含CAD圖紙,螺母,加工,工藝,夾具,設(shè)計(jì),全套,cad,圖紙 畢業(yè)設(shè)計(jì)（論文）中文摘要 本設(shè)計(jì)是基于螺母零件的加工工藝規(guī)程及一些工序的專用夾具設(shè)計(jì)。螺母零件的主要加工表面是外圓及孔系。一般來說，保證平面的加工精度要比保證孔系的加工精度容易。因此，本設(shè)計(jì)遵循先面后槽的原則。并將孔與平面的加工明確劃分成粗加工和精加工階段以保證孔系加工精度。主要加工工序安排是先以支承孔系定位加工出頂平面，在后續(xù)工序中除個(gè)別工序外均用頂平面和工藝孔定位加工其他孔系與平面。夾具選用專用夾具，夾緊方式多選用手動(dòng)夾緊，夾緊可靠，機(jī)構(gòu)可以不必自鎖。因此生產(chǎn)效率較高。適用于大批量、流水線上加工。能夠滿足設(shè)計(jì)要求。 關(guān)鍵詞：螺母類零件；工藝；夾具 畢業(yè)設(shè)計(jì)（論文）外文摘要 Title： The long shaft fork processing technology and fixture design Abstract： This design is the special fixture for machining process for long shaft parts and process design based on. The main processing surface of long shaft parts is cylindrical and holes. In general, ensure the machining accuracy of plane than to ensure the accuracy of the processing easily. Therefore, follow the groove surface after the first principle of the design. And the hole and the plane processing clearly divided into roughing and finishing stages to ensure machining precision. The main process of machining technology is first to support hole positioning processing the top plane, in addition to the follow-up processes are individual processes with the top plane positioning technology and other processing Kong and plane. The special fixture fixture, clamping means more choice of manual clamping, clamping reliable, agencies can not self-locking. Therefore, higher production efficiency. Suitable for large batch, the processing pipeline. Can meet the design requirements.
