Equipment Manufacturing Technology No.02,2016 点获线的固定可确保设计过程中尺寸约束的稳定。 对于本文所涉及的轮胎来说,通过本次设计轮胎三 维模型的过程,发现SolidWorks的特征功能里面的 “包覆”功能特别适合于花纹之类的圆周模型的构 建,此前,笔者也绕了不少弯路,开始建造轮胎花纹 模型时,使用花纹的二维草图进行曲面投影,但是不 能做到花纹侧面垂直于圆心的实际效果,只能放弃 投影曲线建模的思路;最后通过包覆功能,才完成花 纹的建模设计。通过本次设计,笔者感觉SolidWorks 软件功能丰富,只有在实际的应用中,不断总结经 验,才能找到最佳设计思路,达到设计效果。 进行二维图纸的转换,表达出轮胎的断面、花纹等尺 寸,三维设计对于初学设计的人员具有上手快,立体 感强的优点,设计修改方便、快速、简单,更加直观、 清楚。三维实体设计可以任意试验在实物上不允许 的失败,使设计人员不怕失败,勇于创新。作为设计 人员,利用好三维设计工具,对提高设计水平将有巨 大的帮助,同时也希望抛砖引玉,对需要者有所 启发。 参考文献: [1]湛迪强,孔杰.solidworks2014快速入门、进阶与精通[M】. 北京:电子工业出版社,2014. 3结束语 [2】叶修梓,陈超祥.solidworks基础教程:零件与装配体【M]. 北京:机械工业出版社,2007. 3】陈超祥,叶修梓.solidworks高级教程简编【M】.北京:机械工 总之,在实际轮胎外形设计工作中,通过三维模 [型可以将轮胎的外形尺寸准确的表示出来,并可以 业出版社,2010: Tire Three-Dimensional Design and Achieve based on Solidworks Coated XUN Yu-hong 一.LONG Ming-yuan (1.Guizhou Machinery Industy rSchool,Guiyang 550004,China; 2.Guizhou Youruite Industry Co.Ltd.,Guiyang 550001,China; 3.Guizhou Normal University,Vocational&Technical College,Guiyang 550001,China) Abstract:In the actual design,it need three—dimensional model to introduce the product.SolidWorks so ̄ware are used in the three-dimensional design of the tire.It is complete description of the tire from the sketch to complete the design process,especially describes how’’coated”feature achieve circumferential pattern modeling for Solidworks provides a useful attempt in tire design,provide a reference for the relevant designer.

Automatic blanking unit is the first unit of automatic line,providing the work piece and the tray for the entire automated production line. Automatic blanking unit consists of the feeding unit and blanking unit.This paper using Mitsubishi PLC and MCGS touch screen,designed a set of automatic blanking unit system,which can automatically blank.The experimental results show that,the manipulator is running wel1.
