[0025] like Figures 1 to 4 As shown, a plane grinding device for silicon carbide bearings includes a processing table 1, an automatic loading component 3 for inputting bearings is installed on the front side of the processing table 1, a position adjustment component 2 for controlling the movement of the bearing is arranged on the top surface of the processing table 1, a double-sided grinding component 4 for grinding the end surface of the bearing is arranged on the rear side of the processing table 1, a feed pipe 5 is fixedly connected to the right side surface of the processing table 1, a roller 6 is rotatably connected to the bottom of the inner wall of the feed pipe 5, a dust cleaning component 7 is arranged on the surface of the feed pipe 5, and a flow control component 8 for closing the feed pipe 5 is arranged at the end of the feed pipe 5. More specifically, the automatic loading component 3 is used to convey the silicon carbide bearing to be processed into the position adjustment component 2, and the position adjustment component 2 drives the bearing to move along the top surface of the processing table 1, so that the bearing reaches the double-sided grinding component 4. At this time, both ends of the bearing are in contact with the double-sided grinding component 4, and the double-sided grinding component 4 is used to synchronously grind the two end surfaces of the bearing. After the processing is completed, the position adjustment component 2 drives the bearing to continue to move. When the bearing reaches the position of the discharge pipe 5, the bearing will move downward along the surface of the drum 6. The processed bearing can be cleaned by the cleaning component 7 to remove debris on its surface. The discharge pipe 5 can be closed by the flow control component 8, so that the bearing can stay in the discharge pipe 5 to ensure the cleaning time. After the cleaning is completed, the flow control component 8 is used to release the seal and the bearing can be exported.

[0026] The position adjustment component 2 includes a first motor 201, and the first motor 201 is fixedly installed on the bottom surface of the processing table 1.

At least three limiting holes 204 are provided on the surface of the rotating disk 203. It should be noted that by running the first motor 201, the rotating shaft 202 is driven to rotate, which can drive the rotating disk 203 and the limiting holes 204 to rotate. By setting at least three limiting holes 204, when one limiting hole 204 is located below the automatic feeding component 3, feeding can be carried out. At this time, the second limiting hole 204 can be located at the position of the double-sided grinding component 4, so that one bearing is in a grinding processing state, and the third limiting hole 204 is just located at the feeding tube 5 for feeding, so that the three bearings are in different processing steps at the same time.

[0027] The automatic feeding assembly 3 includes an oblique support rod 301, and the oblique support rod 301 is fixedly connected to the front of the processing table 1, and the end of the oblique support rod 301 is fixedly connected to a mounting box 302, and a conveyor belt 303 is provided at the bottom of the inner wall of the mounting box 302, and a feeding tube 304 is fixedly plugged at the bottom of the mounting box 302. More specifically, the bearing to be polished is placed on the surface of the conveyor belt 303, and the bearing is transported by the conveyor belt 303. When the bearing moves to the end of the conveyor belt 303, the bearing will pass through the feeding tube 304 and enter the limiting hole 204 downward, thereby feeding the bearing.

[0028] The double-sided grinding assembly 4 includes a mounting frame 401, and the mounting frame 401 is fixedly mounted on the surface of the processing table 1. A notch is provided on the rear side of the top surface of the processing table 1, and the mounting frame 401 is located in the notch. The top and bottom surfaces of the mounting frame 401 are fixedly mounted with a second motor 402, and a grinding wheel 403 is provided at the output end of the second motor 402. It should be noted that when the bearing rotates to the notch under the action of the limiting hole 204, the upper and lower ends of the bearing will contact the surfaces of the upper and lower grinding wheels 403. At this time, the second motor 402 is operated to drive the grinding wheel 403 to rotate at a high speed, so that the two end surfaces of the bearing can be ground.

[0029] The dust removal assembly 7 includes a liquid storage tank 701, and the liquid storage tank 701 is fixedly installed on the top surface of the feed pipe 5. A water pump 702 is fixedly installed on the surface of the liquid storage tank 701, and the liquid inlet end of the water pump 702 is connected to the inside of the liquid storage tank 701. The liquid outlet end of the water pump 702 is fixedly connected to a liquid outlet pipe 703, and a nozzle 704 is fixedly installed on the surface of the liquid outlet pipe 703. A sewage tank 705 is fixedly connected to the bottom surface of the feed pipe 5, and a discharge pipe 706 is fixedly plugged on the surface of the sewage tank 705.

[0030] The circulation control assembly 8 includes an electric push rod 801, and the electric push rod 801 is fixedly installed on the surface of the feeding tube 5. The telescopic end of the electric push rod 801 is fixedly connected with a baffle 802, and the baffle 802 is movably plugged with the feeding tube 5. It should be noted that when a bearing enters the inside of the feeding tube 5, the electric push rod 801 is operated to drive the baffle 802 to descend, so that the baffle 802 blocks the inside of the feeding tube 5, thereby keeping the bearing inside the feeding tube 5 for a period of time, which is convenient for cleaning the bearing, and can also prevent the cleaning sewage from flowing out from the end of the feeding tube 5. When the cleaning is completed, the baffle 802 can be driven to rise by the electric push rod 801, thereby releasing the closure of the end of the feeding tube 5.

[0031] In summary: the silicon carbide bearing to be processed is conveyed to the position adjustment component 2 by the automatic feeding component 3, and the position adjustment component 2 drives the bearing to move along the top surface of the processing table 1, so that the bearing reaches the double-sided grinding component 4. At this time, both ends of the bearing are in contact with the double-sided grinding component 4, and the double-sided grinding component 4 is used to synchronously grind the two end surfaces of the bearing. After the processing is completed, the bearing is driven to continue to move by the position adjustment component 2. When the bearing reaches the position of the discharge pipe 5, the bearing will move downward along the surface of the drum 6. The processed bearing can be cleaned by the cleaning component 7 to remove the debris on its surface. The discharge pipe 5 can be closed by the flow control component 8, so that the bearing can stay in the discharge pipe 5 to ensure the cleaning time. After the cleaning is completed, the flow control component 8 is used to release the seal and the bearing can be exported. In use, the effect of facilitating automatic grinding of the bearing is achieved, and the two end surfaces of the bearing can be ground at the same time. There is no need to manually flip and adjust the bearing. The operation is simpler during the entire grinding process, which effectively improves the processing efficiency.
