[0030] The limiting assembly 12 includes a positioning ring 121, and a protective gasket 122 is installed on the inner wall of the positioning ring 121 to prevent the outer wall of the quartz crucible from colliding with the inner wall of the positioning ring 121. A plurality of positioning rods 123 are installed on the lower side of the positioning ring 121. A plurality of sockets for the positioning rods 123 to be inserted are provided at the bottom of the groove 15. The positioning rods 123 are inserted into the sockets to keep the positioning ring 121 stable inside the groove 15.

[0031] Through the above structure, the surface treatment device of the present invention adopts a quartz crucible to fix the structure, and the grinding structure is rotated to perform comprehensive grinding. Before the quartz crucible is positioned, a limiting component 12 of a suitable size is selected according to the radius of the lower outer wall of the quartz crucible. The inner wall of the positioning ring 121 in the limiting component 12 is smaller than the radius of the upper outer wall of the quartz crucible. The positioning ring 121 is placed inside the cut groove 15, and the lower part of the quartz crucible is passed into the positioning ring 121. The upper part of the quartz crucible is located above the positioning ring 121, and the quartz crucible is limited.

[0032] When the size of the limiting component 12 is selected to be larger, the quartz crucible will slide down from the inside of the positioning ring 121 and fall to the upper side of the protective plate 16. The quartz crucible is supported by multiple groups of springs 17 on the lower side of the protective plate 16 to prevent the quartz crucible from falling and being damaged.

[0033] Combined with Figure 1 and attached Figure 2As shown, a grinding belt 4 is provided above the quartz crucible positioning assembly 1, and an adjustable transmission assembly 41, a support assembly 42 and an adjustment assembly 43 are provided inside and outside the grinding belt 4.

A mounting plate 5 is connected to the top of the hydraulic rod 2. The adjustable transmission component 41 and the support component 42 are respectively installed on the outside of the connecting shaft 3, and the support component 42 is located below the adjustable transmission component 41.

[0035] The specific method of use is as follows: the hydraulic rod 2 is connected to the rotating device through the top mounting plate 5, and the hydraulic rod 2, the connecting shaft 3 and the external connecting device of the connecting shaft 3 are driven to rotate through the external rotating device, the rotation amplitude is greater than 180° and less than 360°, and it is a reciprocating rotation, the connecting shaft 3 and the axis of the quartz crucible are in the same straight line, after the quartz crucible is positioned, the hydraulic rod 2 is extended to move the grinding belt 4 into the inside of the quartz crucible, and the upper position of the grinding belt 4 is adjusted according to the inner width of the side wall of the quartz crucible through the adjustable transmission component 41, so that the upper part of the grinding belt 4 contacts the inner side of the side wall of the quartz crucible, and the lower side of the grinding belt 4 contacts the quartz crucible. After the bottom of the crucible is reached, the hydraulic rod 2 continues to extend, and the lower side of the grinding belt 4 is in contact with the inner wall of the quartz crucible at multiple locations through the support assembly 42. The support assembly 42 has a telescopic function, causing the grinding belt 4 to loosen on the outside of the adjustable transmission assembly 41 and the support assembly 42. The tightness of the grinding belt 4 on the outside of the adjustable transmission assembly 41 and the support assembly 42 can be adjusted by the adjustment assembly 43. The grinding belt 4 is driven by the adjustable transmission assembly 41, and the position of the quartz crucible does not move. The thickness of the grinding belt 4 is 1-3 cm, and the outer side is an arc-shaped knot with a large contact surface with the inner side of the side wall of the quartz crucible. The inner wall of the quartz crucible is polished by rotating the grinding belt 4.

The supporting assembly 42 is fixedly mounted on the outside of the connecting shaft 3 through the connecting ring 422 .

[0041] Through the above structure, after the grinding belt 4 is pressed against the bottom of the quartz crucible, the support roller 427 is subjected to pressure, which drives the H-shaped frame 425 to move, compressing the multiple sets of springs 426, so that the grinding belt 4 at the support roller 427 is close to the bottom of the quartz crucible. When the H-shaped frame 425 moves, the limiting slide bar 428 slides on the inner side of the inner wall on both sides of the H-shaped frame 425, so that the H-shaped frame 425 slides on the outer side of the rectangular frame 424.
