此次設(shè)計(jì)是對撥叉零件的加工工藝和夾具設(shè)計(jì)，其零件為鍛件，具有體積小，零件復(fù)雜的特點(diǎn)，由于面比孔易加工，在制定工藝規(guī)程時，就先加工面，再以面為基準(zhǔn)來加工其它，其中各工序夾具都采用專用夾具，特別的對于加工大頭孔、槽和鉆小頭孔斜面小孔的工序中，選一面兩銷的定位方式，并以操作簡單的手動夾緊方式夾緊，其機(jī)構(gòu)設(shè)計(jì)簡單，方便且能滿足要求。 FZtI

ABSTRACT VJ(#FA2  
Z4Qq#iHZR  
This design is to dials forks the components the processing craft and the jig design, its components are the forging, has the volume to be small, components complex characteristic,Because the surface is easier than the hole to process, when formulation technological process, first the machined surface, then processes other take the surface as the datum,In which various working procedures jig all uses the unit clamp, special regarding processes the big end of hole, the trough and drills the capitellum hole incline eyelet in the working procedure, Chooses locate mode which two sells at the same time, and operates the simple manual clamp way clamp, its organization design is simple, the convenience also can satisfy the request. kO\aNtK
