自动机凸轮机构的设计与动作协调性分析
|
摘要
针对全自动胶囊生产线自动机工艺动作过程复杂、协调性设计困难的问题,从该自动机的工作原理出发,通过对其结构和运动特性的分析,根据自动机夹囊、顶囊机构运动的协调性原则,提出了用统筹法的搭接网络技术辅助协调设计的思路。根据调设计的特点和搭接网络的要求,基于功能—行为—结构的计算机辅助概念设计了过程模型,采用单代号搭接网络构建了自动机协调设计的多层网络模型。运用搭接网络技术不仅能够完成运动循环图所能完成的工作,还为设计者提供了丰富的设计调整信息,适应了协调设计的模糊性、层次性和继承性要求。研究结果表明:该方法适应了协调设计的要求,方便了产品设计、方案调整和计算机实现,对自动机械凸轮机构协调设计具有借鉴作用。
Aiming at the problem of automatic process of automatic production of capsule production line is complicated and coordinated process design is difficult,starting from the working principle of the automaton,through the analysis of its structure and motion characteristics,according to the coordination principle of the movement of the automatic bladder and the top bag mechanism,the idea of using coordinated network technology to assist coordinated design was put forward.According to the characteristics and design requirements of the spliced network,and the conceptual design model of computer aid based on the function、behavior and structure,single code overlapping network was adopted to constructing a multilayer network model of the coordinated design.The application of lapping network technique can not only complete the work of motion cycle chart,also provide abundant information of the design and adjustment for the designer,to adapt the requirements of fuzzy hierarchy and inheritance for coordination design.The results indicate that the method meets the requirements of coordinated design,facilitates product design,program adjustment and computer implementation,and has a reference function for the coordinated design of automatic mechanical cam mechanisms.
