The reduction gear box body ponents technological process and its the processing hole jig design is includes the ponents processing the technological design, the working procedure design as well as the unit clamp design three parts. Must first carry on the analysis in the technological design to the ponents, understood the ponents the craft redesigns the semi finished materials the structure, and chooses the good ponents the processing datum, designs the ponents the craft route。在工藝設計中要首先對零件進行分析,了解零件的工藝再設計出毛坯的結構,并選擇好零件的加工基準,設計出零件的工藝路線;接著對零件各個工步的工序進行尺寸計算,關鍵是決定出各個工序的工藝裝備及切削用量。 設計說明書 題目 : 氣門挺柱 零件 的工藝規(guī)程設計 學 生: 學 號: 專 業(yè): 班 級: 指導老師: 摘 要 本次設計內(nèi)容涉及了機械制造工藝及機床夾具設 計、金屬切削機床、公差配合與
