摘　　要：针对被动式欧式木窗外框铣削加工效率低、加工精度低和人工劳动强度大等问题,设计一种被动式欧式木窗的双端铣削加工中心,用于被动式欧式木窗外框高效率、高精度铣削加工。通过对木窗铣削工艺的分析,采用计算机辅助设计方法对加工中心结构进行详细设计,利用Solidworks软件对加工中心进行三维建模,基于有限元分析软件对关键支撑零件的强度、刚度进行分析,使用虚拟试验方法验证加工中心的加工效率。研究结果表明,加工中心理论加工效率约为400扇/d,相较于人工加工效率350扇/d,效率提升了14.28%,关键支撑零件的最大应力远小于材料的许用应力,满足使用要求。Aiming at the problems of low milling efficiency,low machining precision and high manual labor intensity of the outer frame of passive European-style wood windows,a double end milling machining center for passive European-style wood windows was designed and used for high-efficiency and high-precision milling of the outer frame of passive European-style wood windows.Through the analysis of the milling process of wood windows,the detailed design of the machining center structure was carried out using computer-aided design methods.Solidworks software was used for three-dimensional modeling of the machining center,and finite element analysis software was used to analyze the strength and stiffness of the key support parts.Virtual experimental methods was used to verify the machining efficiency of the machining center.The results showed that the theoretical machining efficiency of the machining center was about 400 fans/day,compared with the manual machining efficiency of 350 fans/day,the efficiency was improved by 14.28%,and the maximum stress of the key support parts was far less than the permissible stress of the material,which met the requirements for use.
