摘 要 我国社会主义现代化要求机械制造工业为国民经济各部门的技术进步、技术改造提供先进、高效的技术装备，它首先要为我国正在发展的产业包括农业、重工业、轻工业以及其它产业提供质量优良、技术先进的技术装备，同时还要为新材料、新能源、机械工程等新技术的生产和应用提供基础装备。 关键词：装备；制造；铣床；专用夹具； Abstract Chinas socialist modernization requirements for mechanical manufacturing industry sectors of the national economy progress of technology, technical transformation to provide advanced, effective technical equipment, it must first for China is in the development of the industry include agricultural, heavy industry, light industry and other industries provide good quality, technical advanced technical equipment, but also for new materials, new energy, mechanical engineering of production and application of new technology provides the basis of equipment. The present paper is combining the actual production, gm can not meet the production requirements, fixture using universal fixture clamping work-piece efficiency, low labor strength, 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. This fixture can in processing of conventional parts that quality further ascension, and reduce the labor intensity, can guarantee the quality of its products processing precision and batch production, so as to reduce the production cost. Thus fixture use in some extent improve the efficiency of enterprises in practical production. Thus to fixture knowledge know and study the optimal in todays show for important up.
