【正文】 計(jì)（論文） CA10B 后鋼板彈簧吊耳加工工藝及夾具設(shè)計(jì) 攀枝花學(xué)院畢業(yè)設(shè)計(jì)（論文） 摘要 I 摘 要 本次設(shè)計(jì)是對(duì)后鋼板彈簧吊耳零件的加工工藝規(guī)程及一些工序的專用夾具設(shè)計(jì)。后鋼板彈簧吊零件的主要加工表面是平面及孔。所以本設(shè)計(jì)遵循先面后孔的原則。基準(zhǔn)選擇以后鋼板彈簧吊耳大外圓端面作為粗基準(zhǔn)，以后鋼板彈簧吊耳大外圓端面與兩個(gè)工藝孔作為精基準(zhǔn)。在后續(xù)工序中除個(gè)別工序外均用端面和工藝孔定位加工其他孔與平面。 關(guān)鍵詞 后鋼板彈簧吊耳，加工工藝，專用夾具 攀枝花學(xué) 院畢業(yè)設(shè)計(jì)（論文） ABSTRACT II ABSTRACT The design of the plate after spring lug parts of the processing order of the processes and some special fixture design. Spring plate after hanging parts of the main plane of the surface and pore. By the principle known Processing , the plane guarantee precision machining holes than guarantee the machining precision easy. So the design follows the surface after the first hole principle. Plane with holes and the processing clearly divided into roughing and finishing stages of processing to ensure accuracy. After selecting base plate spring lug large cylindrical face as a rough benchmark, After the leaf spring lug large cylindrical end with two holes as a precision technology benchmarks. main processes arrangements after the first spring plate lug large cylindrical face each other benchmarks machined face, End position to further processing out of holes. In addition to the followup processes are individual processes with endpositioning technology and other processing Kong and plane. The entire process of processing machine binations were selected. Key words The empress steel plate spring coil mourns the ear,Process the craft,Appropriation tongs 攀枝花學(xué)院畢業(yè)設(shè)計(jì)（論文） 目 錄 1 目 錄 摘 要 ..........................................................................................................................Ⅰ ABSTRACT .................................................................................................................
