The drawings show the preferred embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0027] The specific embodiments of the present application will be described below with reference to the drawings.

[0028] Embodiment 1

[0029] In this embodiment, a grinding and polishing machine feeding mechanism is proposed, please refer to Figures 1-4 The grinding and polishing machine feeding mechanism includes a tray 5 corresponding to the polishing area of the grinding and polishing machine, as shown in Figure 1 , Figure 3 and Figure 4 , the tray 5 has six positions, and each position has a first groove 13, a second groove 14, a third groove 15 and a fourth groove 16 with the same axis from top to bottom, and a partition groove 17 below the fourth groove 16, and a workpiece groove 18 below the partition groove 17. Further explanation, the first groove 13 has the largest diameter, the diameters of the second groove 14, the third groove 15 and the fourth groove 16 decrease one by one, the diameter of the partition groove 17 is consistent with that of the first groove 13, and the workpiece groove 18 corresponds to the size of the workpiece, i.e. the size of the focal raw material. Further explanation, in combination with the sizes of the first groove 13, the second groove 14, the third groove 15 and the fourth groove 16, the stepped area of each groove is formed.

[0030] Please refer to Figure 3In the embodiment, each slot has a counterweight except the partition slot 17 and the workpiece slot 18, further illustrating that the counterweight matched with the first slot 13 is the first counterweight 8, the counterweight matched with the second slot 14 is the second counterweight 9, the counterweight matched with the third slot 15 is the third counterweight 10, and the counterweight matched with the fourth slot 16 is the fourth counterweight 11. Of course, the partition 12 in the partition slot 17 is provided to contact the fourth counterweight 11, and the partition 12 is in contact with the workpiece, and further illustrating that the depths of the first slot 13, the second slot 14, and the third slot 15 are consistent, and the thicknesses of the first counterweight 8, the second counterweight 9, and the third counterweight 10 are gradually reduced, so that when the partition 12 is pushed to move upward, the third counterweight 10, the second counterweight 9, and the first counterweight 8 will be sequentially out of support of the corresponding steps.

[0031] In combination with the above description, the workpiece just contacting the polishing area of the grinding and polishing machine will push the partition 12 to move upward, so that the third counterweight 10, the second counterweight 9, and the first counterweight 8 will be sequentially out of support of the corresponding steps due to the thickness of the workpiece. During polishing, the thickness of the workpiece is gradually reduced, and under the premise that the distance between the tray 5 and the polishing area is unchanged, the first counterweight 8, the second counterweight 9, and the third counterweight 10 out of support of the corresponding steps will fall into the corresponding steps in turn due to the downward movement of the partition 12 relative to the partition slot 17, until only the fourth counterweight 11 presses the workpiece. The significance of this is that the workpiece will obtain different pressing forces during polishing, for example, all counterweights are pressed on the workpiece during early polishing, and the workpiece is quickly worn by the polishing area of the grinding and polishing machine, during which the weight is reduced due to the corresponding counterweights falling into the steps, until only the fourth counterweight 11 presses the workpiece, and then the friction surface of the workpiece is polished to meet the requirements of the polarized light microscope test.

Further illustrating that the tray 5 has a gap from the polishing area of the grinding and polishing machine, and the gap can be adjusted based on the sliding of the insertion rod 4 in the vertical part of the elbow pipe 3, and of course, after adjustment, the locking part 6 is needed to be locked.

[0033] In the embodiment, Figure 1The shown support 1 is provided with a region for placing the polishing machine, and the polishing machine can be pushed into the placing region.

[0034] The technical features of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.
