【摘要】 在我国提倡木制产品高效利用的今天,木制产品的高利润将会给木业发展带来活力,欧式木窗是附加值较高的产品。本文从欧式木窗的生产实际出发,通过在实践中的调研,设计制造了带有大型推台的专用推台铣床。该设备可将窗扇整体组扇后铣削成型,使欧式木窗在工艺上得以变革。 本文所设计的欧式木窗以生产成本最小化,产品设计质量最优化,生产效率最高化为目的。通过考察研究设计出木窗截面的切削成型形状,计算了该形铣削功和铣削功率,进而确定设备的总功率。总结了专用推台铣床铣削原理和机械结构,设计并制造出适用于欧式木窗的专用推台铣床设备,使欧式木窗在加工工艺上有了进一步的发展,特别是在窗扇的铣削上可以整体周边铣削成型,从根本上解决了木窗结合部分的精度,提高了欧式木窗的产品质量,从而向该产品的产业化迈进了一步。 本文中推台铣床主轴转速达5780r/min,为了考察其运转时的固有频率和谐响应特性,对主轴部件做了动力学分析,确定该主轴为刚性转子,并阐述了为提高主轴动态性能提出的几点措施。然后对该轴系进行动平衡试验,以保证表面质量和工作安全。更多还原

【Abstract】 Nowadays it is advocated that wood products should be used in high efficiency in our country, for high profits with wood products will make wood industry vital, European type wooden window is a kind of wood products which has high additional value. This paper based on the practice of European type wooden window, we designed and made the slide-table miller for special-purpose. The device processes the whole after making the casements combined, which is just the reformation in the technics of the European type wooden window.The paper minimizes the cost of product, make the product design quality supreme, producing efficiently. By researching the process shape of wood window, calculate the power, and assure the total power of the device, it summarizes the theory and the structure of the special-purpose slide-table miller, design and produce the special-purpose slide-table miller for the popular European type wooden window, improve the produce technics of the popular European-style wooden window, specially in the milling of the windows, improve the precision and quality, and puts the first step for industrialization.In this paper, the velocity of the main shaft is up to 5780r/min. In order to examine the inherent running frequency and humorous response characteristics, the paper analyzes the part of the main shaft in dynamics, make sure the main shaft is rigidity rotor, and expatiate some measures to improve dynamic characters of main shaft. Then it tests the inertia balance for the surface quality and safe in working.更多还原
