[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] When in use, first turn on the external power supply so that the annular electromagnet 52 is energized to generate an electromagnetic force, which can have an adsorption force on the iron block 56, so that the protrusion on the iron block 56 slides upward along the through groove on the surface of the movable rod 55, and at the same time, the inclined rod 511 drives the sliding seat 58 to move into the movable groove 57, and drives the polishing wheel 510 to move toward the surface close to the fixed seat 54 through the cross bar 59. When the iron block 56 is adsorbed and fixed on the bottom of the annular electromagnet 52, the polishing wheel 510 is close to the fixed seat 54 at this time, and the personnel moves the two clamping plates 413 away from each other along the groove 412, so that it is convenient for the personnel to place the metal ring 6 on the top of the circular sandpaper board 7, and the surface of the grinding roller 415 is in contact with the surface of the metal ring 6, so that the metal ring 6 can be stably placed;

[0041] After the metal ring 6 is placed stably, the power supply of the annular electromagnet 52 is turned off, so that the annular electromagnet 52 is de-energized to eliminate the electromagnetism. There is no adsorption force between the iron block 56 and the annular electromagnet 52. At this time, the iron block 56 slides downward along the surface of the movable rod 55 by gravity. At the same time, the reverse force of the reset spring 512 in the movable groove 57 drives the sliding seat 58 to move inside the movable groove 57. The sliding seat 58 drives the polishing wheel 510 to move through the cross bar 59 until the surface of the polishing wheel 510 contacts the inner wall of the metal ring 6. The first motor 421 and the second motor 51 are started. The first motor 421 drives the active gear 422 to rotate. Then, when the passive gear 423 on the surface of the active gear 422 rotates, the annular seat 2 and the workbench 3 can be driven to rotate along the top of the bottom plate 1 through the teeth 424, so that the grinding roller 415 on the top of the workbench 3 contacts the metal The outer wall of the ring 6 is polished. At the same time, since the bottom of the frosting plate 416 is in contact with the top of the metal ring 6, the top of the metal ring 6 can also be polished while the workbench 3 rotates, and the circular sandpaper board 7 on the top of the workbench 3 can polish the bottom of the metal ring 6. The first motor 421 drives the movable rod 55 to rotate, and the rotation direction of the movable rod 55 is opposite to the rotation direction of the workbench 3 to avoid the same direction rotation causing the metal ring 6 to rotate at the same time, thereby affecting the normal polishing process. The movable rod 55 drives the fixed seat 54 to rotate on the top of the workbench 3, so that the polishing wheel 510 polishes the inner wall of the metal ring 6. With the help of the electric push rod 53 to lift the fixed seat 54, the metal ring 6 of different heights can be polished within a certain range, which greatly improves the polishing range and quality of the metal ring 6.
