学士学位论文 PAGE PAGE IV 摘 要 本文记述了制备管压圈添装机构的设计过程。设计根据课题要求对普通冲压模具进行了改造。其中，详细阐述了制备管压圈添装机构的主要部件的设计，并作了简要的结构分析；动力源步进电机的选择及动力传动结构的设计；运动结构及其涉及的标准件的选择；制备管的定位及其传输方式的确定；PLC控制系统的程序及其流程；也叙述了设计中特殊部件在UG中建模的方法。这种四杆机构推动的自动填装机构，能够在快速装配压圈的同时保证装配精度，也能保证制备管在装配过程中不被损坏。 关键词：冲压模具；PLC；UG；四杆机构 Abstract This paper chronicles the design process of the adding equipment sector of the preparation of tube pressure ring . The general stamping dies are modified based on the design requirements. In which，the important components of the preparation of tube pressure ring are introduced in detail, and a brief analysis of the structure is also mentioned; the choice of power source of stepping motor and power transmission structure design; campaign structure and involved in the choice of standard parts ; preparation and transmission control position determination; PLC control system procedures and processes; also introduce the special part of the design method for modeling in UG. . This four-bar linkage driven automatic filling bodies, is able to quickly assemble pressure ring assembly while ensuring accuracy, but also ensure the preparation of pipe in the assembly process will not be damaged .
