摘　　要：针对当前铸造中的铸件浇冒口去除方法自动化程度低、劳动强度大等问题,研究铸件浇冒口砂轮自适应切割方法,通过切割机和夹具的运动配合实现铸件浇冒口的自动化去除。为保证切割质量,切割机通过自动进给方式对砂轮的磨损量进行补偿,以保证砂轮始终在最佳切割点进行切割。同时,在SolidWorks中建立砂轮切割装置模型并导入到Adams软件中,对其切割过程进行运动学仿真。仿真结果表明:切割装置可以在最佳切割点实现对铸件浇冒口的自动去除,验证了自适应切割方法的合理性。To solve the problems of low automation and high labor intensity during casting riser removal in current casting industry,an adaptive cutting method using grinding wheel was studied.The automatic removal of casting riser was realized by the movement coordination of cutting machine and fixture.To ensure the cutting quality,the cutting machine compensated for the wear of the grinding wheel through automatic feeding so that the wheel always cut at its best cutting point.At the same time,a cutting model was established in SolidWorks and then imported into Adams to simulate the cutting process.The simulation results show that the cutting device can automatically remove the casting riser at the best cutting point,which verifies the rationality of the adaptive cutting method.
