北华航天工业学院毕业论文 PAGE PAGE 1 摘 要 现代机械加工行业发生着深刻的结构性变化，工艺工装的设计与改良已成为相关企业生存和发展的必要条件。动力装置行业作为一个传统而富有活力的行业，近十几年取得了突飞猛进的发展。在新经济时代，这一行业呈现了新的发展趋势，由此对其动力装置的质量、性能产生了新的变化。输出轴作为动力装置的主要零件，工艺工装的设计与改良直接影响着其质量与性能。 本文首先介绍了输出轴的作用和工艺分析，其次确定毛坯尺寸，然后进行了工艺规程设计，本次设计的是CA6140车床输出轴钻10-φ20孔和车键槽夹具工艺设计，包括加工工件的零件图、毛坯图、夹具装配图、夹具体图和机械加工工艺过程卡片、与工序卡片各一张。 关键词：工艺分析 工艺规程设计 夹具设计 PAGE 2 PAGE 2 Abstract The modern machine-finishing profession is having the profound constitutive change, the craft work clothes design and the Improvement has become the correlation enterprise survival and the development essential condition. The power unit profession takes a tradition but the rich vigor profession, in the recent several years has obtained the development which progresses by leaps and bounds. In the new economical time, this profession has presented the recent development tendency, from this to its power unit quality; the performance has had the new change. The output shaft took the power unit the major parts, the craft work clothes design and the improvement directly is affecting its quality and the performance. This article first introduced the output shaft function and the craft analysis, next the definite semi finished materials size, then has carried on the technological process design, This design is the CA6140 lathe output shaft drill 10-φ20 hole and the keyway slot fixture process design, including the workpiece parts of the workpiece map, blank map, fixture assembly diagram, clip body and mechanical processing process card, and the process of the card Key words： technical analyze the technical rules plan modular design 目 录 TOC \o 1-3 \h \u 1315 摘 要 I 12436 Abstract II 32342 第1章 零件的工艺分析及生产类型的确定 1 19203 1.1零件的作用 1 4237 1.2零件的工艺性 1 5354 1.2.1分析、审查产品的零件图和装配图 1 16855 1.2.2零件的结构工艺性分析 1 8756 1.3确定零件的生产类型 2 19485 第2章 确定毛胚、绘制毛胚简图 3 11283 2.1选择毛胚 3 30481 2.2确定毛胚的机械加工余量和尺寸公差 3 2473 2.2.1毛胚的机械加工余量 3 6811 2.2.2毛胚的尺寸公差 3 25414 2.2.3加工余量、工序尺寸和工差的确定 4 21
