[0023] According to the overall structure of the device, firstly, the support leg 101 and the support seat 2 are symmetrically distributed on both sides of the top of the workbench 103 to enhance stability. The connecting rod 206 is fixedly connected between the covering ring 205 and the connecting plate 204, and is set at a 45° tilt to make the force evenly distributed. The fixed ring 209, the limit block 208, and the slide groove 207 constitute a lifting structure to increase the adjustability of the device. The covering ring 205 is arranged outside the grinding end 305 to avoid debris splashing. The sliding connection between the guide groove 3 and the sliding end 301 guides and positions the bottom processing end 304 so that it can remain stable during use. The connecting end 302 and the fixed ring 209 constitute a rotating structure to meet the needs of complex shape grinding. The grinding end 305 is distributed in an annular manner on the inner surface of the processing end 304 to improve processing efficiency. At the same time, the grinding end 305 is made of elastic grinding sheet material to adapt to the curved surface of the bell shell. The placement seat 402 fixes the workpiece to ensure the stability of the grinding process. The center line of the fixing block 4 coincides with the center line of the placement seat 402 , so that the grinding end 305 maintains uniform contact with the surface of the workpiece when rotating, thereby achieving efficient grinding.

[0024] The supporting legs 101 are symmetrically distributed on both sides of the bottom of the device body 1, the workbench 103 is arranged at the top center of the top plate 102, and the support seat 2 is symmetrically distributed on both sides of the top of the workbench 103. The reinforcement plate 202 is arranged as a group, and a group of reinforcement plates 202 is arranged in an L shape. The covering ring 205 is arranged in a hollow ring shape. The connecting rod 206 is fixedly connected between the covering ring 205 and the connecting plate 204. The connecting rod 206 is inclined at 45°. A group of connecting rods 206 and the covering ring 205 and the connecting plate 204 respectively form a triangular shape. The limit block 208 and the slide groove 207 are slidably connected. The fixed ring 209 forms a lifting structure with the covering ring 205 through the cooperation between the limit block 208 and the slide groove 207, and there are several limit blocks 208.

[0025] The support legs 101 are used as the support of the device, and the support seats 2 are symmetrically distributed on both sides of the top of the workbench 103, which enhances the stability of the device and ensures that the device will not shake during the processing. The reinforcement plate 202 is set in an L shape. This structure enhances the sturdiness of the device. At the same time, the connecting rod 206 is fixedly connected between the covering ring 205 and the connecting plate 204, and the connecting rod 206 is set at a 45° tilt, so that the force distribution during the grinding process is more uniform, which helps to maintain the stability during the processing. The fixed ring 209 forms a lifting structure with the covering ring 205 through the cooperation between the limit block 208 and the slide groove 207, which increases the adjustment performance of the device in structure, and facilitates the grinding end 305 to adjust the height according to the position of the workpiece during processing, so that it can adapt to processing requirements of different heights. The covering ring 205 is set on the outside of the grinding end 305 to avoid the splashing of debris during the grinding process. There are several limit blocks 208, thereby improving the stability of the lifting process.

[0026] The guide groove 3 and the sliding end 301 are slidably connected, and the connecting end 302 forms a rotating structure with the fixing ring 209 through the cooperation between the guide groove 3 and the sliding end 301. The grinding end 305 is distributed in an annular shape on the inner surface of the processing end 304, and the grinding end 305 is set with an elastic grinding disc material.

[0027] The processing end 304 at the bottom is guided and positioned through the sliding connection between the guide groove 3 and the sliding end 301. During the processing, the sliding end 301 can slide in the guide groove 3, ensuring that the grinding device can remain stable during the processing of the bell shell surface. Secondly, the connecting end 302 forms a rotating structure with the fixing ring 209 through the cooperation between the guide groove 3 and the sliding end 301. This design allows the grinding end 305 to rotate, thereby meeting the grinding needs of complex shapes, allowing the grinding head to better adapt to curvature changes and improve the grinding effect. Then, when working, the grinding end 305 is distributed in a ring on the inner surface of the processing end 304, so that the grinding end 305 can fully cover the outer surface of the bell shell, thereby improving the processing efficiency. At the same time, the grinding end 305 is set with an elastic grinding sheet material, so that it can better adapt to the curved surface of the bell shell, reducing the problems of grinding marks and uneven material removal.

[0028] The fixing block 4 is disposed at the top center of the workbench 103 , and the vertical center lines among the fixing block 4 , the placement seat 402 and the grinding end 305 coincide with each other.

[0029] The workpiece is fixedly placed by the placement seat 402 to ensure that the workpiece remains stable during the grinding process. Since the vertical center line between the fixed block 4 and the placement seat 402 coincides with the vertical center line of the grinding end 305, the grinding end 305 can always maintain uniform contact with the surface of the workpiece during rotation, thereby achieving an efficient grinding effect.

[0030] Working principle: First, the support base 2 is symmetrically distributed on both sides of the top of the workbench 103, which enhances the stability of the device and ensures that the device will not shake during the processing. The reinforcement plate 202 is set in an L shape. This structure enhances the firmness of the device. At the same time, the connecting rod 206 is fixedly connected between the covering ring 205 and the connecting plate 204, and the connecting rod 206 is set at a 45° tilt, so that the force distribution during the grinding process is more uniform, which helps to maintain the stability during the processing. The fixing ring 209 is connected to the slide groove 207 through the limit block 208. The cooperation between the two and the covering ring 205 constitutes a lifting structure, which increases the adjustment performance of the device in structure, so that the grinding end 305 can be adjusted in height according to the position of the workpiece during processing, so as to adapt to the processing requirements of different heights. The covering ring 205 is arranged on the outside of the grinding end 305 to avoid the splashing of debris during the grinding process. There are several limit blocks 208, so as to improve the stability of the device during the lifting process. Then, the processing end 304 at the bottom is guided and positioned through the sliding connection between the guide groove 3 and the sliding end 301. During the processing, the sliding end 304 is guided and positioned. The moving end 301 can slide in the guide groove 3, ensuring that the grinding device can remain stable during the processing of the bell-shaped shell surface. Secondly, the connecting end 302 forms a rotating structure with the fixing ring 209 through the cooperation between the guide groove 3 and the sliding end 301. This design allows the grinding end 305 to rotate, thereby meeting the grinding needs of complex shapes, allowing the grinding head to better adapt to the curvature change and improve the grinding effect. Then, during work, the grinding end 305 is distributed in an annular manner on the inner surface of the processing end 304, so that the grinding end 305 can fully cover the bell-shaped shell surface. The outer surface of the shell improves the processing efficiency. At the same time, the grinding end 305 is made of elastic grinding material, so that it can better adapt to the curved surface of the bell-shaped shell, reduce grinding marks and uneven material removal problems, and finally fix the workpiece by the placement seat 402 to ensure that the workpiece remains stable during the grinding process. Since the vertical center line between the fixed block 4 and the placement seat 402 coincides with the vertical center line of the grinding end 305, the grinding end 305 can always maintain uniform contact with the surface of the workpiece during rotation, thereby achieving an efficient grinding effect.
