摘　　要：层合速凝技术是当前关注的热点,陶瓷零件快速成型机是基于这种技术的,具有很广的发展前景。针对快速成型机的升降机构和水平运动机构,对原方案的结构进行了分析,根据分析结果,对原方案进行了改进设计,并通过Workbench的静力学分析,可知改进后的升降机构的最大变形位于工作台中部,为了减小铺料台在Y方向的变形,提出了在铺料台下方焊接加强筋的方案;而改进后的水平装置的变形发生在料斗装置附近,且导轨的变形非常小,水平装置满足刚性的要求,分析结果说明结构设计的合理性,为快速成型机结构的设计和改进提供了一种思路和参考依据。Laminated quick setting technology is the hotspot now, and rapid prototyping machine for ceramic parts has a good prospect based on this technology. A lining at the lifting mechanism and a horizontal movement mechanism of rapid prototyping machine, the structure of the original scheme is discussed, based on the results of the analysis, and the scheme is improved in design, and through the static analysis of workbench, the maximum deformation of the lifting mechanism of the improved is located in central of the platform, and in order to decrease the Y direction deformation, proposes the reinforcement rib program welded below the paving platform; the deformation of horizontal mechanism of the improved occurs in the hopper device near, and the deformation of the guide rail is very small, and the level device meets the rigid requirements, and the analysis results for the design and improvement of the rapid prototyping machine provide a new idea and reference.
