Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-Figure 10 A grinding and trimming machine tool shown in the figure comprises a grinding table 1, on which a rotatable grinding wheel 49 is arranged, and on which a vacuum adsorption assembly 2 is arranged, and the vacuum adsorption assembly 2 comprises two groups of vacuum adsorption units 21, a negative pressure unit 22 and a flip unit 23, and the vacuum adsorption unit 21 comprises an adsorption disk 211, and the adsorption disk 211 can rotate, and a plurality of adsorption holes are opened on the adsorption disk 211, and the adsorption disk 211 can move horizontally, and the flip unit 23 can make the two adsorption disks 211 rotate; The two adsorption plates 211 are pressed against each other during the rotation process, and the two adsorption plates 211 are separated from each other when they are rotated to a horizontal state; The negative pressure unit 22 includes a negative pressure pipe 221 , which can move vertically and is connected to the suction disk 211 located at the lower side of the two vacuum suction units 21 .

[0023] The suction disk 211 located at the top moves horizontally to expose the suction disk 211 located at the bottom, and the workpiece is placed on the suction disk 211 located at the bottom. The negative pressure pipe 221 is connected to the suction disk 211, so that negative pressure is formed in the suction hole, and the workpiece is adsorbed on the suction disk 211. The grinding wheel 49 rotates to grind the inner ring, outer ring and top of the workpiece, and grinds off the burrs on the upper surface of the workpiece. The suction disk 211 located at the top moves horizontally to the top of the workpiece, and the negative pressure pipe 221 moves downward. The flipping unit 23 drives the two suction disks 211 to rotate, so that the positions of the two suction disks 211 are swapped, and the workpiece is flipped. The two suction disks 211 move closer to each other during the rotation process to press the workpiece between them. After the workpiece is flipped, the suction disk 211 located at the top moves horizontally to expose the suction disk 211 and the workpiece located at the bottom, and the negative pressure pipe 221 moves upward to be connected to the suction disk 211 located at the bottom, and the grinding wheel 49 rotates to grind off the burrs on the other surface of the workpiece.

[0024] The workpiece is adsorbed on the adsorption plate 211, so that the workpiece is more stable and not easy to shake during the grinding process. After the upper surface of the workpiece is polished, the two adsorption plates 211 are turned over to drive the workpiece to turn over, and the other side of the workpiece is polished, which has a better grinding effect on the workpiece, eliminates the operation of manually turning the workpiece, improves the grinding efficiency, saves time and effort, and when the workpiece is turned over, the two adsorption plates 211 are close to each other to press the workpiece tightly to prevent the workpiece from falling during the turning process and improve stability.

At the same time, the fixed frame 212 compresses the release spring 219 to store force in the release spring 219. When the adsorption plates 211 are flipped to a horizontal state, the release spring 219 drives the two adsorption plates 211 to move away from each other, so that the upper adsorption plate 211 is separated from the workpiece and moves horizontally, exposing the workpiece for grinding.

The stabilizing frame 233 drives the fixed frame 212 to rotate through the stabilizing plate 231 and the sliding bar 218. The fixed frame 212 drives the adsorption disk 211 to rotate, so that the adsorption disk 211 flips. When the fixed frame 212 and the adsorption disk 211 move horizontally, the translation cylinder 210 drives the stabilizing plate 231 to move horizontally, the stabilizing plate 231 drives the fixed frame 212 to move horizontally, and the fixed frame 212 drives the adsorption disk 211 to move horizontally.
