When the workpiece is placed on the grinding platform, the clamping plate can be pushed to reset through the setting of the reset spring and the contact plate. Therefore, under the setting of the anti-slip pad, the friction between the clamping plate and the workpiece can be increased to prevent the workpiece from falling during grinding, thereby improving the stability of the workpiece during grinding and ensuring the quality of grinding; Furthermore, when one side of the workpiece is polished, the drive motor is started, and the drive motor drives the flip rod to rotate through the engagement of the first bevel gear and the second bevel gear. The rotation of the flip rod drives the clamping plate connected to the workpiece to flip, thereby achieving the effect of flipping the processed workpiece and polishing both sides. The polishing efficiency of the polishing device can be improved, and there is no need for manual flipping by the staff.

[0015] 2. When the left and right clamping plates have finished clamping the workpiece, the first bevel gear on the left is meshed with the second bevel gear. As the workpiece turns over, the first rotating rod can drive the second rotating rod at the front end of the fixed plate to rotate under the setting of the belt. At this time, as the workpiece rotates toward the front end, the ground of the workpiece can be sprayed with water for humidification. When the other side is subsequently polished, the polishing effect can be improved while avoiding dust and flying chips during polishing, thus protecting the safety of the staff and avoiding environmental pollution. At the same time, the polishing effect can be further improved. 3. When the left and right movable plates move inward to clamp the workpiece, the bottom of the movable plate slides along the positioning rod to squeeze the airbag, and the airbag is squeezed to deliver the internal air to the air jet through the delivery hose, thereby automatically removing impurities on the surface of the workpiece, avoiding the influence of impurities on the grinding effect, avoiding impurity particles from scratching the workpiece during grinding, and improving the quality stability of the grinding device after grinding.

At this time, the workpiece is processed by starting the grinding disc 3 on the mechanical arm 2. When the workpiece is placed on the grinding platform 4, the electric telescopic rod 7 is started to make the movable plate 6 slide along the positioning rod 5. At this time, as the sliding clamping plate 12 of the movable plate 6 clamps the workpiece, as the clamping plate 12 clamps the workpiece, the flip rod 10 moves outward to drive the second bevel gear 11 to mesh with the first bevel gear 9. At this time, the workpiece can be clamped stably. When the clamping plate 12 stops clamping the workpiece, the reset spring 14 and the contact plate 15 are set. The clamping plate 12 can be pushed to reset, so under the setting of the anti-slip pad 13, the friction between the clamping plate 12 and the workpiece can be increased to prevent the workpiece from falling during grinding, thereby improving the stability of the workpiece during grinding and ensuring the quality of grinding. When one side of the workpiece is ground, the driving motor 8 is started, and the driving motor 8 drives the flipping rod 10 to rotate through the engagement of the first bevel gear 9 and the second bevel gear 11. The rotation of the flipping rod 10 drives the clamping plate 12 to connect with the workpiece to flip, so that the workpiece can be flipped and polished on both sides, which can improve the grinding efficiency of the grinding device and does not require manual flipping by staff.

As the workpiece flips, the first rotating rod 16 can drive the second rotating rod 18 at the front end of the fixed plate 19 to rotate under the setting of the belt 17. The rotation of the second rotating rod 18 can drive the disc 20 to rotate. As the disc 20 rotates, the positioning bolt 21 rotates along the outer circumference of the disc 20 to move the groove push rod 22. The groove push rod 22 moves back and forth left and right under the limit of the storage box 24. When it passes through the lower right end of the feeding bin 27, After water is added to the storage box 24 through the one-way feed port 28, as the groove push rod 22 pushes the sealing plate 23 to move back and forth, the water inside the storage box 24 is squeezed along the guide pipe 25 into the water spray port 26. At this time, as the workpiece rotates toward the front end, the ground of the workpiece can be sprayed with water to humidify it at the same time, so that when the other side is polished later, the polishing effect can be improved while avoiding dust and the spread of flying chips during polishing, thereby protecting the safety of the staff and avoiding environmental pollution, and at the same time, the polishing effect can be further improved.
