摘 要
此次設(shè)計是對撥叉零件的加工工藝和夾具的設(shè)計，其零件為鍛件，具有體積小，零件復(fù)雜的特點。由于面比孔易加工，在制定工藝規(guī)程時，就先加工面，再以面為基準來加工其他，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，其機構(gòu)設(shè)計簡單，方便且能滿足要求。
關(guān)鍵詞 撥叉，加工工藝，專用夾具，設(shè)計
Abstract
The design Plectrum parts of the process and fixture design, and its parts forgings, small size, complex parts due to the surface hole Yi processing, the development of the technological procedure, on the first machined surface, and then to the surfaceprocessing as a benchmark to other, in which the process fixture with special fixtures, special process for processing the bulk of holes, slots and slant hole drilling small head positioning, the election of two sells, and simple to operate manual clampingclamping manner, its structure is simple, convenient and can meet the requirements.
