铣60°斜面夹具设计毕业论文.docVIP

摘 要 车床主要用于加工回转表面，和孔的加工，另外还可以加工平面，所以车床广泛用于各种机械加工中，是目前使用最为广泛的机床之一。而本文中提到的上刀架位于车床的方刀架的下方，用于定位方刀架，由此可见上刀架在车床中的重要的作用。 本文主要研究了上刀架的加工，从铸造毛坯到成品件的各个加工的工序的工艺过程，以及在各个工艺中所用到的机床、夹具、量具等设备，还有切削速度、切削用量等。最后还研究了上刀架的四面三工位铣和两侧面铣的夹具的设计，进行基准的选择，误差分析，夹紧力计算等。而通过查阅各种资料，了解了加工过程中的各种的要求和要素，特别是加工用量的选择，通过大量的计算和分析最终得到了一套完整的数据。而在夹具的具体设计中也查阅了大量的夹具方面的文献，最终得到了一套较优的装夹方案。 通过本文会了解到上刀架的完整的加工工艺过程以及四面三工位和两侧面铣的夹具的完整信息。 关键词：工艺过程 切削用量 基准 误差分析 夹紧力 ABSTRACT Lathe is mainly used for machining a surface of revolution and some hole machining, and some of the plane can be processed too. So lathe is widely used in various mechanical processing, which is one of the most widely used tools currently. And the top slide mentioned in the text is located on the bellow the turret on the lathe. Used to locate the turret, thus the top slide is on an important role of the lathe. This paper mainly studies the processing of the top slide, from blank to end product, as well as the various processes used in machine tools, jigs, gauges and other equipment, and cutting speed, cutting data and so on. Finally, studies on the fixture design of the four sides and three-position of the top slide milling and face milling on both sides, selecting the standard, analyzing the error, computing the clamping force. The author of this article searched a variety of literature, known the processing elements of the requirements, especially selecting the cutting data, author did a lot of calculation and analysis and finally got a complete set of data. The design of the fixture was also the author searching a lot of the fixture literature, finally got a set of optimum clamping scheme. Through this paper you will get the on the complete machining process of the top slide, and complete information of four sides and three-position milling and face milling on both sides of the top slide fixture. Key words: craft process cutting data standard error analysis clamping force 目 录 绪 论 1 第一章 零件的分析 2 1.1零件的作用 2 1.2零件的工艺分析 2 1.3零件图 2 第二章 工艺规
