用设计方法学的理论,从应用角度出发,以某产品的辅助成型设备——卷边-滚压螺纹二合一机的设计过程,论述在具体的设计问题中为满足特殊的功能要求而进行的机械设计综合,并应用平面机构尺寸综合理论,即图解法,对人们所熟悉的常见机构进行设计综合。在机械设计过程中,为快速达到某种设计意图,设计方法学理论具有一定的适用意义。 Using the theory of design methodology, from the application point of view, with a product of the auxiliary molding equipment - Crimping - Rolling thread combo machine design process, discussed in the design of specific issues to meet specific functional requirements The mechanical design synthesis, and the application of the theory of plane size theory, that is, graphic method, familiar to people familiar with the design and synthesis of institutions. In the process of mechanical design, in order to quickly reach a certain design intent, design methodology theory has a certain significance.
