[0002] Metallographic analysis is one of the means of testing and analyzing materials, aiming to reveal the true structure of the material. To conduct metallographic analysis, it is necessary to prepare samples that can be used for microscopic observation and inspection, namely metallographic specimens. In metallographic analysis, it is very important to select and prepare representative specimens. Usually, the preparation of metallographic specimens involves the following steps, including sampling, mounting, grinding, polishing and corrosion.

[0003] In the existing metallographic sample polishing machine, a lot of waste slag and debris will be generated during the grinding process. These waste slag and debris will fall on the workbench. If these waste slag and debris are adsorbed on the workbench, the staff can only wipe them slowly with a rag, which is extremely inconvenient to clean. Therefore, we propose a metallographic test polishing machine to solve the above problem. Utility Model Content

The movable disc 13 has a grinding disc 14 fixedly mounted on the bottom surface of the rotating disc 13, and an annular sleeve 15 is fixedly connected to the bottom surface of the rotating disc 13. Two connecting posts 16 are fixedly connected to the inner side wall of the annular sleeve 15, and a group of soft brushes 17 are fixedly connected to the bottom surface of each connecting post 16. The metallographic sample can be adsorbed by the strong suction cup 8, and the rotating disc 13, the grinding disc 14 and the annular sleeve 15 can be driven to rotate simultaneously by the driving motor 11 and the rotating rod 12. In this way, when the grinding disc 14 is grinding, the annular sleeve 15 can be used to drive the connecting posts 16 and the soft brush 17 to rotate, so that the residue and debris inside the annular groove 6 can be cleaned during the grinding work.

[0023] A protective door 18 is hinged on the front of the shell 2 through a hinge, and a door handle 19 is fixedly connected to the front of the protective door 18. An observation window 20 is provided on the front of the protective door 18. Two sets of legs 21 are fixedly connected to the bottom surface of the base 1, and the bottom end of each leg 21 is fixedly connected to an anti-slip seat 22. A control panel 23 is fixedly connected to the right side of the shell 2.

The rotating ring 27 and the reinforcing rods 28 can have a good reinforcement effect on the rotating disk 13, which can make it more stable when the driving motor 11 drives the rotating disk 13 to rotate.

[0025] The working principle of the utility model is:

[0026] When the device is used, the staff first connects the device to an external power source, then places the metallographic sample to be polished on the strong suction cup 8, and uses the control panel 23 to start the strong suction cup 8, so that the strong suction cup 8 firmly adsorbs the metallographic sample, and then uses the control panel 23 to start the electric push rod 9, and uses the electric push rod 9 to drive the lifting plate 10, the drive motor 11 and the rotating disc 13 to move downward until the bottom surface of the grinding disc 14 contacts the surface of the metallographic sample. At this time, the staff uses the control panel 23 to start the drive motor 11, and uses the drive motor 11 to drive the rotating rod 12 and the rotating disc 13 to rotate. When the rotating disc 13 rotates, it will drive the grinding disc 14 and the annular sleeve 15 to rotate simultaneously. In this way, when the grinding disc 14 grinds the metallographic sample, it can also drive the connecting column 16 and the soft brush 17 to rotate, so that the residue and debris generated when the inside of the annular groove 6 is polished can be cleaned into the inside of the debris collection box 4 by the discharge hole 7. The above is the entire operation process of the device.
