由单一机器人实现多平台铆接工艺的研究

Research on Riveting Process for Multi-Platforms by A Single Robot

由于铆接工艺多用于铝材连接,导致此工艺在汽车白车身上的使用具有局限性,因此在白车身上应用较少。为解决铆接工艺与其他基础工艺的兼容问题,基于此情况进行了多种铆接工艺的整合研究,设计由单一机器人实现多种铆接工艺的方案,并进行验证分析。主要包括自冲铆接工艺、无铆钉自冲铆接工艺、旋转攻丝铆接工艺的整合,同时对其他工艺的后期融合进行了客观分析。验证结果表明,多种铆接工艺整合可以在一个生产节拍中提高设备开动率,降低生产成本和能源消耗。

Due to the fact that riveting technology is mostly applied for aluminum connection,its application in automotive Body In White(BIW)is limited.To solve the issue of compatibility between riveting process and other basic processes,this paper studied the integration of multiple riveting processes,designed a scheme to achieve multiple riveting processes emplying a single robot,validation analysis was conducted.The integration mainly includes self-piercing riveting process,rivetless self-piercing riveting process and rotary tapping riveting process.Meanwhile this paper also objectively analyzed the post-integration of other processes.The validation results indicate that the integration of multiple riveting processes can improve equipment start-up rate,reduce production costs and energy consumption in a single production cycle.
