The invention relates to vibration grinding equipment, and belongs to the field of valves. The vibration grinding equipment is mainly used for grinding a valve sealing surface. The vibration grindingmachine is mainly composed of a motor (1), belt wheels (2 and 4), a belt (3), a main shaft (5), a bearing (6), an eccentric wheel (7), a spring retaining piece (8) and a grinding disc (9). The main working principle includes that the motor drives the belt wheels to rotate, and the belt wheels (4) and the main shaft (5) are driven by the belt to rotate at a certain speed ratio, the main shaft drives the eccentric wheel to rotate together, and the grinding disc generates vibration in the horizontal direction and the circumferential direction, so that parts placed on the grinding disc generate autorotation and revolution, and grinding movement is realized. The vibration grinding machine is simple in structure, the vibration amplitude and the vibration frequency can be adjusted, and the vibration grinding equipment is suitable for the valves of plane sealing pairs such as grinding gate valves and stop valves.
