During polishing, two polishing wheels are rotated to achieve the grinding effect.

[0003] However, there are also some problems in the use of the polishing device. For example, in the process of polishing the valve stem, the waste chips from grinding will directly float in the air, causing a certain impact on the surrounding environment, and some of the waste chips adhere to the polishing wheel, thereby affecting the subsequent polishing and grinding effect of the valve stem. That is, the waste chips adhere to the polishing wheel, making the surface roughness of the polishing wheel insufficient, which can easily cause slipping during polishing, and it is difficult to ensure that the valve stem is fully polished.

[0023] When the valve stem needs to be polished, the valve stem is placed between the first polishing wheel 2 and the second polishing wheel 3, so that the telescopic component arranged at the lower end of the second polishing wheel 3 drives the second polishing wheel 3 to move until the first polishing wheel 2 and the second polishing wheel 3 are tightly fitted with the valve stem. During the movement of the second polishing wheel 3, the fixed rod 403 begins to slide in the through hole opened on the sliding plate 402, that is, under the action of the sliding plate 402 and the fixed rod 403, the right side of the fixed plate 401 can be stably supported to avoid deformation of the fixed plate 401, and then the first polishing wheel 2 and the second polishing wheel 3 start to rotate (the first polishing wheel 2 and the second polishing wheel 3 are driven to rotate by a rotating shaft arranged at the output end of the motor at the rear end of the device), and as the first polishing wheel 2 and the second polishing wheel 3 rotate, the valve stem closely fitted therewith can be polished, and during the polishing process, the cleaning brush 404 is closely fitted with the first polishing wheel 2 and the second polishing wheel 3, so as to realize brushing and cleaning of the surfaces of the first polishing wheel 2 and the second polishing wheel 3 as the first polishing wheel 2 and the second polishing wheel 3 rotate, under the action of the cleaning brush 404, waste chips are prevented from adhering to the surfaces of the first polishing wheel 2 and the second polishing wheel 3 and affecting the subsequent polishing effect of the first polishing wheel 2 and the second polishing wheel 3;

[0024] The dust removal component 5 is connected to the cleaning component 4; the dust removal component 5 includes a fixed dust collection plate 501, and the fixed dust collection plate 501 is installed at the lower end of the fixed plate 401, and the ventilation duct arranged on the fixed dust collection plate 501 is penetrated and arranged on the fixed plate 401; the dust removal component 5 also includes a filter box 502 and a negative pressure fan 503, and the filter box 502 is connected to the fixed dust collection plate 501 through the pipeline, and the negative pressure fan 503 is connected to the filter box 502 through the pipeline. Then, the filter box 502 and the negative pressure fan 503 are both arranged on the upper surface of the fixing plate 401; the dust removal assembly 5 also includes a filter plate 504, a fastening plate 505 and a fastening screw 506, and the filter plate 504 is arranged on both sides of the front side of the filter box 502, and the fastening plate 505 is installed on the filter plate 504, and the fastening screw 506 is arranged on the fastening plate 505 through the fastening screw 506, and the fastening screw 506 is connected to the filter box 502 through the threaded hole opened on the filter box 502;

[0025] As the first polishing wheel 2 and the second polishing wheel 3 rotate, the valve stem is polished, and then the negative pressure fan 503 starts to work, and the negative pressure fan 503 starts to generate negative pressure. At this time, the dust and waste chips generated during the polishing process are absorbed by the fixed dust suction plate 501. At this time, the dust and waste chips enter the filter box 502 through the pipeline. A filter plate is fixedly arranged on the left side of the filter box 502 (the diameter of the hole on the filter plate fixedly arranged on the left side of the filter box 502 is smaller than the hole on the filter plate 504).

Filtering is performed to achieve the purpose of filtering waste debris and dust in the air. When the filter plate 504 needs to be disassembled, replaced or cleaned, the fastening screw 506 is rotated to make the fastening screw 506 start to move away from the fastening plate 505 until the fastening screw 506 is no longer connected to the threaded hole opened on the filter box 502. At this time, the fastening screw 506 can be removed, and then the filter plate 504 is pulled until the filter plate 504 is no longer in contact with the grooves opened on the front and rear sides of the filter box 502. At this time, the filter plate 504 can be disassembled, replaced or cleaned.
