摘　　要：并联机床的结构实际上是并联机器人机构。分析并联机床所采用的并联机构的自由度,发现并联机床基本上基于三、六自由度并联机构开发的,其他自由度的并联机床比较少,其与各种自由度的并联机构的比例基本一致。同时对各种自由度的并联机床的结构特点进行分析,重点对具有重大研究价值的五轴并联机床结构进行详细分析。In fact the structure of parallel machine tool is the parallel mechanism. After analyzing the degree of freedom of the parallel mechanisms by which the parallel machine tools are developed, the results indicate that the structure of the most parallel machine tools are three or six degree of freedom parallel mechanisms while the other degree of freedom＇ s parallel machine tools are fewer. The dis- tribution of degree of freedom of parallel machine tools is accordant with the one of parallel mechanisms. The design features of the different degree of freedom＇ s parallel machine tools are also analyzed respectively, and the design feature of five axis parallel machine tools is introduced especially for his highly values.
