【正文】 簽名： 年 月 日 注：任務書必須由指導教師和學生互相交流后，由指導老師下達并交所屬系部畢業(yè)設計（論文）領導小組審核后發(fā)給學生，最后同學生畢業(yè) 論文等其它材料一起存檔。目前機械加工工藝技術向著高精度、高效率高自動化發(fā)展。 機床夾具設計以培養(yǎng)和提升技術人員的機床夾具設計能力為主旨，強調應用能力的培養(yǎng)，以“必需、夠用”為度，著眼于解決現場實際問題，突出綜合素質的培養(yǎng)。 Mechanical manufacturing technology is produced in the human production practice and continuous development. Current machining technology development towards high precision, high efficiency, high automation. Machine tool fixture is indispensable important craft equipment in the machinery manufacturing, can guarantee the machining quality, improve production efficiency, reduce production costs, reduce labor intensity and realize automatic production process, using a dedicated fixture can also change the purpose of the original machine tools and to expand the use of the machine tool, realize one machine can, therefore, clamping apparatus play an important role in the mechanical processing, a large number of special machine tool fixture used for mass production to provide the necessary conditions. Machine tool fixture design to foster and promote the technical personnel of machine tool fixture design. 第 1 頁 目錄 100龍上方箱加工工藝 ...........................................................................................................................................2 100龍上方箱加工工藝分析 ............................................................................................................................ 2 100龍上方箱的工藝要求及工藝分析 ......................................................................................................... 2 100 龍上方箱技術要求 ............................................................................... 4 ......................................................................................................................................... 4 底面平面的加工 ............................................................................................. 5 配作兩個連接孔 ............................................................................................. 5 加工兩個半圓 ................................................................................................. 5 加工頂面螺紋 ................................................................................................ 5 確定定位基準 ...................................................................................................................................................... 6 粗基準的選擇 ................................................................................................. 6 選擇的原則 .................................................................................................... 6 .................................................................................................................................................. 6 工序的合理組合 ............................................................................................. 7 的集中與分散 ................................................................................................. 7 工階段的劃分 ................................................................................................. 8 加工工藝路線方案擬定 .................................................................................. 9 零件毛坯要求 ...........................................................................................................
