[0023] Please refer to Figures 1 to 4 , a water return ring of a metallographic specimen polishing machine, comprising an outer ring body 1 and an inner ring body 2.

[0024] The outer ring body 1 includes an outer edge portion 1a and an end cap portion 1b. The outer edge portion 1a is in a cylindrical shape, that is, the top surface and the bottom surface of the outer edge portion 1a are both open. The end cap portion 1b is disposed at the top opening of the outer edge portion 1a. More specifically, the two may be integrally provided. The middle position of the end cap portion 1b is a round hole 1b2 for cooperating with the polishing disc 3. More specifically, a groove matching the outer shape of the outer edge portion 1a is provided on the metallographic specimen polishing machine, and the polishing disc 3 is rotatably connected to the middle position of the groove. After the outer ring body 1 is inserted into the groove, the center of the round hole 1b2 corresponds to the axis of the polishing disc 3, and the diameter of the round hole 1b2 is smaller than the diameter of the polishing disc 3.

[0025] The inner ring body 2 includes an outer upper positioning portion 2a, an inner lower support portion 2b, and an inclined middle portion 2c. A filter paper 2c1 is also provided on the middle portion 2c. More specifically, a plurality of mounting grooves are provided on the middle portion 2c, and the outer edge of the filter paper 2c1 is provided with a frame matching the outer shape of the mounting groove and is snap-fitted and fixed in the mounting groove.

[0026] The inner ring body 2 is detachably connected to the outer ring body 1 and is located inside the outer edge portion 1a. More specifically, the two may be snap-connected. In the connected state, the bottom surface of the lower support portion 2b is flush with the bottom surface of the outer edge portion 1a.

[0027] After the inner ring body 2 is connected to the outer ring body 1, the two are installed together on the metallographic sample polishing machine. Accordingly, the inner diameter of the lower support part 2b of the outer ring body 1 needs to be larger than the grinding disc 3. After the two are installed together on the metallographic sample polishing machine, the groove on the metallographic sample polishing machine is separated by the inner ring body 2, the grinding disc 3 is in the inner ring body 2, and the water outlet in the groove is outside the inner ring body 2. During the grinding process, the grinding liquid and debris are splashed out under the action of the centrifugal force of the grinding disc 3, passing through the filter paper 2c1 on the inner ring body 2, and the grinding liquid passes through the filter paper 2c1, leaves the inner ring body 2, and enters the water outlet in the groove; the debris is intercepted by the filter paper 2c1. After the grinding is completed, the inner ring body 2 and the outer ring body 1 are taken out, and the inner ring body 2 is removed for cleaning.

[0028] In some embodiments, a circular groove 1b1 is disposed in the middle of the end cover portion 1b, and a circular hole 1b2 is disposed on the bottom surface of the circular groove 1b1, with a diameter smaller than the circular groove 1b1. An annular portion 1b3 is formed between the circular hole 1b2 and the inner wall of the circular groove 1b1.

[0029] During the grinding process, the grinding fluid and debris may partially splash upwards under the centrifugal force of the grinding disc 3. After the circular groove 1b1 is designed, the grinding fluid and debris splashed upwards will remain in the circular groove 1b1, which is convenient for cleaning.

[0030] In some embodiments, the inner ring body 2 is composed of at least two modules that are assembled in the radial direction and can be separated. In this way, the inner diameter of the lower support part 2b of the outer ring body 1 does not need to be larger than the grinding disc 3, that is, the modules are first assembled into the inner ring body 2 in the groove on the metallographic sample polishing machine, and then the outer ring body 1 is installed. Correspondingly, the middle part 2c of the inner ring body 2 can extend below the grinding disc 3.

[0031] Furthermore, the portion of the lower support portion 2b close to the middle filter paper 2c1 is inclined toward the middle filter paper 2c1.

[0032] Furthermore, the bottom surface of the end cover portion 1b has a circle of circular enclosure 1b4 coaxial with the circular hole 1b2, and the circular enclosure 1b4 is used for connection with the inner ring body 2.

[0033] Furthermore, the lower support portion 2b is provided with a first magnet 2b1, and the first magnet 2b1 is used to magnetically attract the module to the metallographic sample polishing machine.
