摘　　要：为提升球形阀芯的表面质量,本文提出了一种恒压控制的球形阀芯表面精密研磨装置。以杯型磨具为基础,氧化铝研磨膏为研磨介质,采用磨具和阀芯接触后同时旋转的方式实现对阀芯表面的精密研磨加工,并开发单片机实现对研磨力的采集与控制;采用有限元方法对研磨过程中的研磨压力进行分析,以提供相关理论基础;最后,采用最佳参数对球形阀芯进行了试验,以验证装置的有效性。加工后球形阀芯表面形貌均匀、质量较好,粗糙度为Ra 0.06μm。To improve the surface quality of spherical valve cores,this paper proposes a precision grinding device for spherical valve core surfaces with constant pressure control.Based on a cup-shaped grinding tool and using alumina abrasive paste as the grinding medium,the device achieves precision grinding of the valve core surface by rotating both the grinding tool and the valve core after contact.A microcontroller is developed to collect and control the grinding force.The finite element method is used to analyze the grinding pressure in the grinding process to provide the relevant theoretical basis.Finally,experiments are conducted on spherical valve cores using optimal parameters to verify the effectiveness of the device.The results show that the surface morphology of the spherical valve core is uniform and of high quality,with a roughness of Ra 0.06 μm.
