[0026] Beneficial effects of the present invention:

[0027] 1. Place the shaft parts that need magnetic grinding into the grinding container, convey the liquid required for grinding into the grinding container, then add the grinding medium and lubricant into the grinding container respectively, and drive the grinding medium through the grinding body to grind the shaft parts placed in the grinding container under the action of magnetic force; flip the grinding container by rotating the rotating shaft, at this time, the grinding liquid, grinding medium and shaft parts slide and enter the processing frame respectively, the grinding liquid passes through the hollow sealing plate and is discharged to the lower end, the external water source is sucked and conveyed to the inside of the water distribution pipe by the water pump, and sprayed to the outer wall of the shaft parts and the grinding medium in the processing frame through multiple cleaning nozzles, and the water stains attached to the outside of the shaft parts are cleaned, and at the same time, the crankshaft is driven to rotate by the first servo motor, and the crankshaft drives the connecting rod to rotate along the pin shaft, so that the pin shaft drives the processing frame to shake along the grinding container, and the shaft parts in the processing frame are flipped, thereby improving the discharge efficiency and cleaning effect of the shaft parts after grinding and reducing residues.

[0028] 2. The external air is sucked and transported to the first hollow block through the blower. The first hollow block transports the external air to the second hollow block and the third hollow block respectively. The air is continuously compressed to spray the external air into the processing frame through the inclined holes, and the shaft parts and grinding media in the processing frame are air-dried, which is convenient for rapid drying of moisture. There is no need to transport the shaft parts, which reduces damage to the shaft parts. While air-drying, the pin shaft drives the processing frame to shake along the grinding container, flips the shaft parts and grinding media, and improves the processing efficiency of the shaft parts after magnetic grinding.

[0029] 3. When the processing frame is rotated to discharge, the grinding liquid passes through the hollow sealing plate and then passes through the first filter block and the second filter block in turn, and then falls into the top surface of the liquid outlet guide plate, so that the grinding liquid and debris slide along the liquid outlet guide plate to the inclined drainage block, and then are discharged to the outside from the recovery port, which is convenient for the recycling of waste liquid; after opening the hollow sealing plate, the shaft parts slide along the top surface of the first filter block and are discharged to the outside for collection; the grinding medium that falls with the shaft parts passes through the first filter block and then falls into the top surface of the second filter block, and the grinding medium slides along the second filter block to the inside of the abrasive discharge box, and slides out from one side of the inside of the abrasive discharge box, which is convenient for the classification and collection of shaft parts, grinding media and grinding liquid, simplifies the operating process of magnetic grinding of shaft parts, and makes the discharge and collection work more convenient.

[0030] 4. After placing the shaft parts to be ground into the grinding container, the polishing agent and brightener required for grinding are respectively transported to the corresponding solution tanks, and the grinding media (such as abrasives) are transported to the abrasive box. Then, the output shaft of the forward and reverse motor drives the screw to rotate, pushing the moving block to slide along the T-shaped block. At the same time, the corresponding polishing agent and brightener are discharged through the electric valve and fall into the grinding container, and the appropriate dosage is selected through the flow meter.

[0031] 5. The output shaft of the second servo motor drives one of the rotating rods to rotate, so that the metering block rotates. When the metering slot is at the upper end, the grinding medium inside the abrasive box enters the metering slot. As the metering block rotates, the grinding medium inside the metering slot falls into the grinding container, which facilitates the delivery of an appropriate amount of grinding medium to the grinding container, ensuring the appropriate and accurate feeding of grinding media, polishing agent and brightener, and improving the grinding effect and product quality.
