摘要: 为解决自动钻铆系统离线编程过程中定位点的偏置问题,提出了以修正量为基础的定位点间接测量方法。该方法首先采用代理技术获取定位点,并通过可视化交互平台实现定位点的批量定义,然后采用AUTOMATION接口对定位点实施偏置,并基于模板文件实现定位点的整体偏移,进而通过线性规划方法求出最终的定位点。以某型钣金零件为例,实现了定位点的间接测量。

Abstract: To solve the locating points'offset problem in the off-line program process of the automatic drilling & riveting system, the indirect measurement method of the locating points based on correction was proposed. Firstly, the locating points were obtained by Agent technology. And a visual interactive definition platform was set up to define the locating points interactively. Secondly, the AUTOMATION interface was applied to correct the locating points and a template document was used to manage the global offset of the locating points. Then, the final locating points were determined by linear programming. Finally, an example of sheet metal parts was presented to demonstrate the implementation of the proposed method.
