摘要: 涡旋盘是影响滤油机制冷系统涡旋压缩机性能的主要部件,在逆向工程反求基础上,通过激光扫描方式获取涡旋盘点云数据,比较了接触式测量和非接触式测量的优缺点。利用Imageware进行了点云数据处理,通过Imageware导入扫描所得到的点云,选择保留原始数据,在显示中选择隐藏选择对象,对剩下的点云部分进行圈选,直到点云近似于一条直线。基于CATIA软件平台对涡旋盘进行了重构和反求,运用在点云上生成断面功能,将实体部分隐藏,在截出图形上选择点列,切换到创成式外形设计模式,构建新的曲线和平面,按照涡旋盘实体对图形进行倒角等修改获得最终涡旋盘成品。Abstract: Scroll Plate is the main component affecting the performance of the scroll machine. Based on the Reverse Engineering,this paper has obtained the scroll point cloud data via laser scanning and compared the advantages and disadvantages of the contact measurement with the non-contact measurement at the same time. After using the Image ware into the processing point cloud data,the scroll' s reconstruction and reverse based on the CATIA software platform have carried out. This paper has absorbed the advanced technology and promoted the achievements, progress and technical innovation. More importantly,this study has further validated the principle of work of the scroll machine. This paper provided the new technology and methods for the scroll machine' s product design and manufacturing,greatly improved the precision of product design and manufacturing and realized the paperless processing,and the product development cycle has been shortened.
