摘　　要：机器人打磨系统在加工不同种类铸件时需要更换相应的夹具,此步骤极大降低了机器人打磨产线的自动化程度与加工效率。针对以上问题,文中提出一种适用于管类铸件的可在一定尺寸范围内通用的夹具系统。首先,确定了管类铸件的夹紧需求,设计了相应的夹具组合夹紧方案,总结出一套不损伤铸件表面的夹具夹紧动作。随后,为夹具系统设计了相应的液压回路,并通过PLC配合压力继电器实现夹具动作顺序的控制。最后,对夹具平台的各辅助设备进行了整体布局,绘制液压夹具系统整体模型,并对夹具平台主体部分进行了有限元分析,证明其结构的可靠性。The robot grinding system needs to replace the corresponding fixture when processing different kinds of castings. This step greatly reduces the automation and processing efficiency of the robot grinding production line. This paper puts forward a kind of general fixture for the size of casting, which can be used in a certain range. Firstly, the clamping requirements of pipe castings are determined, the corresponding fixture combination clamping scheme is designed, and a set of fixture clamping action without damaging the casting surface is summarized. Then, the corresponding hydraulic circuit is designed for the fixture system, and the fixture action sequence is controlled by PLC and pressure relay. Finally, the overall layout of the auxiliary equipment of the fixture platform is carried out, the overall model of the hydraulic fixture system is drawn, and the finite element analysis of the main part of the fixture platform is carried out to prove the reliability of its structure.
