機床夾具是零件在機床上加工時，用以裝夾工 件和引導(dǎo)刀具之間的一種工藝裝備，現(xiàn)代夾具有很多種類：按使用機床分為車床、銑床 夾具。 此次設(shè)計是對機械制造技術(shù)基礎(chǔ)課程相關(guān)知識的綜合運用，培養(yǎng)了我們分析問題，解決問題以及查找資料的能力，為以后的學(xué)習(xí)和工作打下良好的基礎(chǔ)。其中銑床夾具中用到對刀塊和定位鍵，以利于銑削加工。 編號 210901112109011118 南京航空航天大學(xué)金城學(xué)院 畢業(yè)設(shè)計 題 目 法蘭盤零件的工藝規(guī)程及工裝設(shè)計 南京航空航天大學(xué)金城學(xué)院 本科畢業(yè)設(shè)計（論文）誠信承諾書 本人鄭重聲明：所呈交的畢業(yè)設(shè)計（論文）（題目： 法蘭盤零件的工藝規(guī)程及工裝設(shè)計 ）是本人在導(dǎo)師的指導(dǎo)下獨立進行研究所取得的成果。鉆床 夾具中用到鉆套，其作用是確定鉆頭等道具的軸線位置，防止道具在加工過程中發(fā)生偏斜。 關(guān)鍵詞 : 工藝規(guī)程，專用夾具，定位方案， UG 三維設(shè)計 畢業(yè)設(shè)計（論文）報告紙 ii The Process Procedures and Tooling Design of CA6140 lathe ring flange Based on UG Abstract A specialized main specialized course that “mechanical manufacturing engineering is studied is machinery , rely mainly on studying machining technology and jig to design technological discipline , have very strong practicality , require that should contact production practices closely in the learning process, at the same time it has prehensive the very strong one The task of this subject is according to the characteristics of final drive cover to finish a process of order. I designed two sets of special fixture which include rough milling of surface and drilling. Among them, the milling machine fixture used the knife block and positioning key which facilitate the milling process. Drilling jig used in drill set, which role is to determine the location of the axis to prevent the occurrence of tool deflection in the processing. UG NX is famous 3D product software of Siemens pany. The design process mainly uses UG to do modeling, fixture stereogram, and the animation of the installation. This design is the foundation of mechanical manufa
