[0006] Further description of the utility model: a first sealing ring is installed between the suction cup and the suction cup connecting seat; and a second sealing ring is installed between the suction cup connecting seat and the rotary joint connecting seat.

[0007] Further description of the utility model, the suction cup is a cylindrical structure.

[0008] Further description of the utility model, the lifting drive device adopts a cylinder.

[0009] The beneficial effects of the utility model are:

[0010] This design uses a suction cup to adsorb the workpiece at its bottom, and then controls the suction cup to descend through the lifting drive device so that the bottom surface of the workpiece contacts the grinding disc, and controls the suction cup to rotate through an external rotary drive device to grind the workpiece. During the rotation process, the suction cup connecting seat and the rotary joint connecting seat will rotate with the suction cup, and a bearing is connected between the lifting ring connecting seat and the rotary joint connecting seat and is limited by the air pipe, so the lifting ring connecting seat does not rotate with the suction cup, and one end of the air pipe is connected to the rotary joint connecting seat through a rotary joint, so the air pipe will not rotate with the suction cup, and will not affect the air path, ensuring that the suction cup is in a negative pressure state to adsorb and fix the workpiece. After the processing is completed, the lifting drive device controls the lifting chain to rise, and the workpiece is manually removed, thus completing one round of processing. This setting has low labor intensity and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
