专用卧式双面镗床设计 摘 要 机械制造业是国民经济的基础产业,它的发展直接影响到国民经济各部门的发展,也影响到国计民生和国防力量的加强,因此,各国都把机械制造业的发展放在首要位置。随着机械产品国际市场竞争的日益加剧,各大公司都把高新技术注入机械产品的开发中,作为竞争取胜的重要段。改革开放以来，我国机械制造业充分利用国内外两方面的资金和技术，进行了较大规模的技术改造，使制造技术、产品质量和水平及经济效益有了很大地提高，为推动国民经济发展起了重要作用。 但与工业发达的国家相比，我国机械制造业的水平还存在阶段性的差距，主要表现在产品质量和水平不高，技术开发能力不强，基础元器件和基础工艺不过关，生产率低下，科技投入严重不足等。我们应该正视现实，面对挑战，抓住机遇，深化改革，以振兴和发展中国的机械制造业为己任，以使我国的机械制造业在不太长的时间内，赶上世界先进水平。 SPECIAL-PURPOSE HORIZONTAL-TYPE TWO-SIDED BORING LATHE DESIGNS ABSTRACT Machinery manufacturing industry is the foundation of the national economy, the development of a direct impact on sectors of the national economy development, but also affect the Guojiminsheng and the strengthening of national defense forces, therefore, machinery manufacturing countries regard the development on top. With the machinery of international competition in the market growing, major high-tech companies put into the development of machinery products, as a competition to win the important paragraph. This paper is on the horizontal boring double-sided fixture for the processing and machine tool design for the note. This demand for machine tools: the two face at the same time boring. This paper includes special fixture, the spindle box for machine design and analysis of the need. Through the design of the machines function and function of decomposition, and the processing of the workpiece to the design of the processing machine dedicated to the programme. By way of the choice and positioning of the workpiece process of analysis, and parts of the process map and machine the size of contact analysis, the horizontal boring machine double the overall design programme. In order to achieve the requirements of automated production, the paper also fixture on the hydraulic system carried out a detailed description. Since reform and opening up, Chinas machinery industry take full advantage of both domestic and foreign funds and technology for the large-scale technological transformation, manufacturing technology
