2、 是一种参数化的计算机辅助设计(CAD)和计算 机辅助制造(CAM)系统。CAD 功能使当今制造业公司的工程、设计以及 制图能力得以自动化。CAM 功能为现代机床刀具提供了 NC 编程,以便使 用 UG 设计模型来描述完成的部件。 按照设计要求,最后用 UG 及 AutoCAD 软件进行绘图,包括系统二维 装配图、三维装配。 关键词关键词 煤粉;定量;供料机构;UG;三维造型 - II - Quantitatively Feeding MechanismS Design Of Pulverized Coal Abstract Quantitatively pulverized coal fee
3、ding mechanism is designed for coal-fired power when the viscosity of the great lignite is used, The main process is transporting quantitative coal to the designated boiler. So the emphasis of the design is how to feed coal quantitatively, the structure of the quantitatively feeding mechanism is not
4、 complex, but as it is used in coal, the have high demands. It hopes that the design can improve the precision degree based on the mechanism working now, and feed coal Quantitatively. This system design adopts UG software .It creates the assembly drawing of three dimensions .At the same time, it also creates the assembly drawing of two dimensions . UG is a king of CAD/CAM system that it is provided with alternant function. The function of project CAD makes automatization of
