[0024] Working principle: when grinding the sound insulation cover, due to the need to meet the requirements of different grinding stages, it is necessary to frequently replace grinding wheels of different coarsenesses to carry out the operation during grinding. During grinding, due to the need to replace the grinding wheel 6 back and forth, the position of the sound insulation cover needs to be adjusted back and forth during the replacement process. When adjusting the grinding, the accuracy of the grinding is affected, and the molding effect of the sound insulation cover is affected; therefore, a corner grinding device for the sound insulation cover is proposed to address the above problems; during the grinding process, first place the sound insulation cover to be ground flat on two placement plates 19, and make one side wall of the sound insulation cover contact with the rotating sleeve 20, then push the sound insulation cover to make the slider 14 move in the limiting slide groove 13 until the side wall of the sound insulation cover moves to contact with the grinding wheel 6, start the second motor 11, and make the second gear The wheel 12 rotates, forcing the small gear ring 7 to drive the grinding wheel 6 to rotate, so that the edges and corners of the sound insulation cover can be polished; when the grinding wheel 6 needs to be replaced for polishing, the first motor 9 is started to rotate the first gear 10, forcing the large gear ring 8 to drive the central column 2 to rotate, and then the rotating disk 3 drives the fixed seat 4 and the grinding wheel 6 to rotate, and at the same time the rotating shaft 5 drives the small gear ring 7 to rotate until the small gear ring 7 rotates to mesh with the second gear 12, so that the replacement of the grinding wheel 6 can be completed quickly, which is suitable for the needs of different coarse and fine grinding wheels in different polishing stages. During the replacement process, the position of the sound insulation cover does not need to be adjusted back and forth, which ensures the accuracy of the polishing, improves the molding effect of the sound insulation cover, greatly shortens the replacement time, and greatly improves the work efficiency.

[0025] During the grinding process, the water inlet pipe 27 is connected to a water pump, and the delivery pipe 30 is connected to a fan. The water pump and the fan work simultaneously, so that water flows into the hollow tube 25 through the water inlet pipe 27, and is finally sprayed out through the nozzle 26 in the form of fine water mist. These water mists can effectively cover and absorb the dust in the air and the debris generated during the grinding process, greatly reducing the suspended particulate matter in the air, thereby achieving efficient dust reduction effect. At the same time, the fan external to the delivery pipe 30 blows out strong winds through the air inlet 28. These winds not only help to diffuse the water mist, so that it covers the entire working area more evenly, but also help to quickly discharge the dust-laden air, reduce the exposure time of workers in high-dust environments, and protect their health.
