摘要随着科学与技术的发展，金属切削加工技术的日趋成熟，加工技术在世界的工业范围内都有了显著的提高。我国造船业发达，用于造船的钢板在使用前往往需要进行坡口和侧面的加工，以满足船体焊接加工和使用者对焊接质量的要求。进行此项加工的常规设备主要是龙门铣，大型刨床。由于利用率低，加工质量不高，劳动强度大，刀具寿命短、更换频繁、调整也比较困难。为此特地设计适用大型船用钢板侧面、坡口加工的大型绿色船用铣边机。对于提高生产效率具有重要的现实意义。49743
论文介绍了大型船用铣边机的设计。首先，了解传统船用铣边机的构造，确定设计和改造方案。在设计过程中通过现设计由链轮链条组成的新型板料输送机构，使钢板能够快速达到预定铣削位置进行铣削，并且在机床两侧安装输送装置，能够实现在一次输送中实现钢板两边都能够铣削的效果，生产效率大大提高。最后，利用Pro/e进行建模和虚拟样机的装配。
结果表明，本次设计可以顺利达到设计任务的要求，完成板料的输送要求，同时提高了加工效率。

Abstract Process technology has experienced a significant improvement on a world scale with the development of science and technology, along with the maturity of metal cutting technology. It’s known to all that China owns a prosperous shipbuilding industry. In order to satisfy the requirement of actual welding quality, steel plate for shipbuilding section and industrial boiler tends to process the grooves and sides before used. The conventional equipments which handle the process involve gantry milling and large-size planer. However, there are three problems: firstly, the equipment is labor-intensive and under-utilization; secondly, it is hard to guarantee the width and precision of the steel sides; thirdly, a rapid failure of cutter easily appears and it needs frequent maintenance and replacement. Therefore, the customized milling machine for shipbuilding section is designed and it is undoubtedly of realistic significance to improve process efficiency.
This thesis has explained the design the large milling machine for shipbuilding section. First of all, the scheme design is based on the structure of traditional milling machine. Then the new type conveying mechanism, made up of chains and chain gears, is able to deliver steel plate to fixed positions to mill. Also, conveying devices are installed along both sides of machine tool so that the two sides of steel plate can be milled during one transmission. Finally, it is advised to evaluate the milling machine with finite element analysis and re-optimize the work. In addition, the installation and emulation of virtual prototype by using Pro/e is tested.
The result shows that this design has met two requests: conveying the steel plate successfully and improving the efficiency.
