拨叉钻孔夹具(铣床钻床).doc

毕业设计(论文)题目
摘要
随着全球制造产业的区域转移整个制造行业竞争的加剧,所有机械加工生产单位都面临提高生产效率的问题。
本论文是结合目前实际生产中,常常发现仅用通用夹具不能满足生产要求,用通用夹具装夹工件生产效率低劳动强大,加工质量不高,而且往往需要增加划线工序,而专门设计的铣床钻床夹具,主要包括夹具的定位方案,夹紧方案、对刀方案、钻模套方案,夹具体与定位键的设计及加工精度等方面的分析。可以有效的减少工件加工的基本时间和辅助时间,大大提高了劳动生产力,从而可以有效地减轻工人的劳动强度和增加劳动效率。

ABSTRACT
With the global transfer of manufacturing industry in petition throughout the manufacturing industry, all production units are facing machining to improve production efficiency. In the machining process technology and equipment as the workpiece clamping fixture, in improving the production efficiency has its particular advantages. Especially in the machining process, with appropriate processing aids. (Such as fixtures) so powerful in the improved production efficiency, so plex parts processing as possible, conventional machining parts to further enhance the quality and reduce labor intensity, in ensuring quality of products, while mass production of precision, thus reducing production costs . To some extent increase the use of fixture actual production efficiency of enterprises. Thus the understanding of knowledge and learning fixture in today's priority is obviously important.
This paper bined with the current actual production, often found only universal fixture can not meet the production requirements, workpiece clamping fixture with the general low productivity of labor power, processing quality is not high, and often need to increase the marking process, a specially designed Types of milling fixture, including fixture locating scheme, clamping program, tool programs, folders and location specific key aspects of the design and analysis of precision machining. Workpiece can effectively reduce the time and support the basic time, greatly improving labor productivity, which can effectively reduce the labor intensity and increase labor efficiency
