During operation, the grinding mechanism 4 and the vertical adjusting component 2 are started, in the working process of polishing a workpiece, the grinding mechanism 4 vibrates to drive the first connecting piece 3 to generate displacement variation along the vertical direction, at this time, the two ends of the displacement sensor 5 detect displacement information generated between the first connecting piece 3 and the second connecting piece 204 along the vertical direction, after receiving the displacement information, the controller controls the first motor 202 to drive the screw 203 to rotate, so that the first connecting piece 3 carries out displacement adjustment along the vertical direction, and the first connecting piece 3 drives the grinding mechanism 4 to move together in the process of displacement adjustment. When the displacement information is overlarge, the distance between the first connecting piece 3 and the second connecting piece 204 is increased, so that the distance between the grinding mechanism 4 and the workpiece in the vertical direction is too short, the grinding mechanism 4 grinds the workpiece to a larger thickness, at the moment, the controller controls the first motor 202 to reversely rotate, so that the screw rod 203 reversely rotates to drive the first connecting piece 3 to gradually approach the second connecting piece 204 upwards in the vertical direction and generate displacement, and the grinding mechanism 4 is driven to gradually keep away from the workpiece; when the displacement information is too small, the distance between the first connecting piece 3 and the second connecting piece 204 is reduced, so that the distance between the grinding mechanism 4 and the workpiece in the vertical direction is far, the grinding thickness of the workpiece by the grinding mechanism 4 is small, at the moment, the first motor 202 is controlled to rotate positively through the controller, the screw 203 is driven to rotate positively at the same time to drive the first connecting piece 3 to move downwards and gradually away from the second connecting piece 204 in the vertical direction and generate displacement, the grinding mechanism 4 is driven to approach the workpiece gradually until the displacement information detected by the displacement sensor 5 meets the requirement of the grinding thickness, the detected displacement information is transmitted to the controller, the controller does not adjust the first motor 202 any more, the work for adjusting the grinding thickness of the workpiece is completed, the control of the grinding thickness in the working process of the grinding mechanism 4 is realized through the displacement sensor 5, the first motor 202 and the controller, and the grinding precision is improved; the housing 201 prevents debris generated during the grinding process from entering the interior of the vertical adjustment assembly 2 and eroding the assemblies, thereby prolonging the service life of the grinding apparatus.
