Therefore both in the mechanical processing industry is a vital link.In machine tool of mechanical parts of the process, in order to ensure the processing precision of the workpiece, first of all to guarantee the workpiece holds the correct position on the machine, then by clamping the workpiece in the correct position is fixed, this task is by the machine tool fixture. For single and small batch production, the use of universal fixture should be as far as possible, so that the production cost of the workpiece can be reduced. But because the universal fixture is suitable for various workpiece clamping, so clamping tend to spend more time and the operation is complex, the production efficiency is low, it is difficult to guarantee machining accuracy, so it is necessary to design a special fixture.The design content involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement and other aspects of knowledge.Keywords ： process, process, cutting dosage, clamping, positioning目錄1 序 言12 零件的分析22.1零件的形狀22.2零件的工藝分析23 工藝規(guī)程設(shè)計43.1 確定毛坯的制造形式43.2 基面的選擇43.3 制定工藝路線43.3.1 工藝路線方案一53.3.2 工藝路線方案二53.3.3 工藝方案的比較與分析63.4 選擇加工設(shè)備和工藝裝備73.4.1 機床選用73.4.2 選擇刀具73.4.3 選擇量具73.5 機械加工余量、工序尺寸及毛坯尺寸的確定73.6確定切削用量及基本工時94 夾具設(shè)計204.1 研究原始質(zhì)料204.2 定位、夾緊方案的選擇214.3切削力及夾緊力的計算214.4 誤差分析與計算224.5鉆套、襯套、鉆模板設(shè)計與選用234.6 確定夾具體結(jié)構(gòu)尺寸和總體結(jié)構(gòu)264.7 夾具設(shè)計及操作的簡要說明27總 結(jié)27致 謝28參 考 文 獻306
