机器人打磨工作站关键技术及其应用

Key Technology and Its Application of Robot Cleaning and Grinding

铸件毛坯表面存在大量的飞边、毛刺,不仅影响铸件外形美观,而且严重影响铸件的产品性能和使用寿命。针对发动机缸体、缸盖等大型、内腔复杂的铸件,设计了一种发动机铸件智能打磨工作站,开发了具有自主知识产权的机器视觉技术、信息化技术等,并进行了应用验证。通过机器人作业与铸造工艺、工装夹具有效融合,产品生产效率提升了20%以上,生产合格率达到了97%以上,用工成本降低了20%以上,显著改善了清理打磨现场的粉尘和噪音污染等,满足了打磨机器人在铸件清理打磨环节日益增多的应用需求。

There are a lot of flash and burr on the surface of the casting, which not only affects the appearance, but also seriously affects the product performance and service life of the casting. For large castings with complex inner cavities such as engine cylinder block and cylinder head, an intelligent grinding workstation for engine castings is designed in this paper. Machine vision technology and information technology with independent intellectual property rights are developed and verified. Through the integration of the robot operation, casting process and tooling fixture effectively, the production efficiency has been increased by more than 20%, the production qualification rate has reached more than 97%, and the labor cost has been reduced by more than 20%. The working environment is improved significantly, and the dust and noise pollution at the cleaning and grinding site are reduced, which meets the increasing application needs of grinding robot in the cleaning and grinding of castings.
