[0050] There is a fixed connection structure between the fixing plate 3 and the controller body 1. In order to solve the installation problem between the fixing plate 3 and the controller body 1, in some embodiments of the utility model, a positioning through hole 304 is arranged around the central through hole 303 of the fixing plate, and a positioning threaded hole 104 is arranged on the first end face of the grinding and polishing controller body 1. The positioning threaded hole 104 of the controller body 1 matches the position of the positioning through hole 304 of the fixing plate, and the fixing piece used to install the fixing plate and the controller body passes through the positioning threaded hole 104 of the controller body 1 and the positioning through hole 304 of the fixing plate to fix the two.

[0051] The precision grinding and polishing controller also includes a floating axis 2, the structure of which is referenced Figure 2 The floating shaft 2 is columnar and includes a first end 201 and a second end 202 along its axial direction.

The outer diameter of the floating shaft 2 is smaller than the size of the central through hole 101 of the controller body 1 and the central through hole 303 of the fixing plate. The floating shaft 2 passes through the central through hole 101 of the controller body 1 and the central through hole 303 of the fixing plate, and a movable connection structure is formed between the three. The first end 201 and the second end 202 of the floating shaft 2 extend to the outside of the central through hole 101 of the controller body 1 and the outside of the central through hole 303 of the fixing plate respectively; the outer wall of the second end 202 of the floating shaft 2 is formed with a threaded structure.

[0052] The floating shaft 2 can be designed as a solid structure or a hollow structure. Considering the overall weight reduction of the product, in this embodiment, the floating shaft 2 is designed as a hollow structure with a central through hole 203 running through the axial direction thereof.

[0053] The grinding and polishing control device also includes a support plate 4, the structure of which is shown in FIG. Figure 4 , the first end 201 of the floating shaft is connected to the support plate 4; since the floating shaft 2 is a structure that can float up and down relative to the controller body 1, when the floating shaft 2 moves, it will drive the support plate 4 to move up and down synchronously.

[0054] The grinding and polishing control device also includes a wear-resistant disc 5, the structure of which is shown in FIG. Figure 5a and Figure 5b , having a central through hole 503 that passes through the first disk surface 501 and the second disk surface 502 of the disk body, for mounting the crystal to be polished.

After being mounted on the floating shaft 2, the elastic member 802 is stopped by the control instrument body 1. In this embodiment, the elastic member 802 is a spring.

[0057] The pressure regulating nut 801 is connected with the thread structure of the second end 202 of the floating shaft. When the pressure regulating nut 801 is adjusted along the floating shaft 2, the tension of the elastic member 802 can be adjusted.

[0058] The fixed plate 3 and the wear-resistant disk 5 (on the side of the first end face 501) are connected as a whole through the fixed pillar 6. A fixed pillar installation 305 is provided on the fixed plate 3, and a fixed pillar installation hole 504 is also provided on the wear-resistant disk 5.

The support plate 4 contacts the crystal to be polished and exerts pressure on the crystal to be polished. The position of the support plate 4 is adjusted according to the size of the crystal to be polished. Figure 8 Pull the floating shaft 2 in the upward direction as shown, rotate the pressure adjusting nut 801 downward to adjust, the compression of the elastic member 802 increases, the pressure generated by the elastic member 802 increases, the downward pressure of the support plate 4 decreases, and the pressure on the crystal decreases; rotate the pressure adjusting nut 801 upward to adjust, the compression of the elastic member 802 decreases, the pressure generated by the elastic member 802 decreases, and at this time, the position of the floating shaft 2 is adjusted downward, and the downward pressure of the support plate 4 increases.
