分离叉内侧面铣夹具的设计 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，导致机械加工生产单位都面临提高生产效率的问题。而在机加过程中作为装夹工件的工艺装备的夹具，在提高生产效率方面有其显著的优势。特别是在在切削过程中，配以适当的加工辅助工具。（如夹具）等有力于提高企业生产效率，使得许多复杂零件的加工成为可能，常规零件加工的质量进一步提升，并降低劳动强度，在保证产品质量加工精度的同时批量生产，从而降低生产成本，从而夹具的使用在某种长度上提高实际生产企业的效益。因而对夹具知识的认识和学习，在今天显的优为更重要起来。 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度大，加工质量不高，而且往往需要增加划线工序，而专门设计的一种铣床夹具，主要包括夹具的定位方案、夹紧方案、对刀方案，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的加工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。 关键词：高效，设计，制造，机床夹具 Abstract With the global manufacturing industry throughout the manufacturing industry regionally competition intensifies, so mechanical processing production units are facing improve production efficiency. And in the machine add process as clamping work-piece process equipment fixture in improving production efficiency aspects has its special advantages. Especially in cutting process in, match with proper processing auxiliary tools. (such as fixture) strong in the improve production efficiency, make many complex parts processing becomes possible, conventional parts processing quality further ascension, and reduces the labor intensity, to ensure the product quality processing precision in the meanwhile batch production, so as to reduce the production cost, thus fixture use in some length improve the benefit of the actual production enterprise. Thus to fixture knowledge know and study the optimal in todays show up for more important. The present paper is combining the actual production, often find using universal fixture cannot meet only production requirements, using universal fixture clamping work-piece production efficiency low labor intensity, processing quality is not high, and often need to increase crossed process, and special design of a milling machine fixture, mainly including fixture positioning scheme, clamping, of cutter scheme, the concrete and the TAB folder design and machining precision analysis. Can effectively reduce the processing time and workpiece basic non-productive
