并联机床工作空间解析系统的开发

Development of the Analytical System of Working Space for Parallel Mechanism Type Machine Tools

以丰田工机公司的HexaM并联机床为模型,讨论了刀架和刀架铰链的改造以及螺母高度等并联机床零部件的形状和尺寸对工作空间的影响,开发了对应倾斜滑动型、垂直滑动型、伸缩型以及回转型并联机床的工作空间解析系统.通过实验结果与仿真结果的对比,证明了所开发软件的正确性,该软件有助于新的并联机床的开发.

Taking HexaM machine developed by Toyoda Machine Works Co. as a model, this paper discussed the influence of the shape and dimension of parts of the parallel mechanism type machine tools on the working space, an analytical system for calculating the working space ot parallel mechanism type machine tools was developed. It can be adapted to various types of parallel mechanism including tilting type, perpendicular type, telescopic type and revolving type. The developed software is proved to be effective by comparing the results of experiment and simulation. Moreover, it is useful for develop the new parallel mechanism type machine tools.
