[0022] Embodiment 1 refers to Figure 1 , Figure 2This embodiment provides a positioning fixture for a ring-shaped quartz product, including a fixed plate 1 and a metal ring 3. The upper end of the fixed plate 1 is provided with 6 evenly distributed mounting grooves 11, the center of the 6 mounting grooves 11 is located on a circle centered on the fixed plate 1. A magnet 4 is fixed in the mounting groove 11. A quartz ring 2 is placed on the upper surface of the fixed plate 1, and a metal ring 3 is placed on the upper surface of the quartz ring 2. The quartz ring 2 is fastened and clamped by the magnetic attraction between the magnet 4 and the metal ring 3, and the quartz ring 2 can be removed or replaced by removing the metal ring 3. A protective layer is provided on the outside of the metal ring 3 to avoid scratching the quartz ring 2. The shape of the mounting groove 11 includes, but is not limited to, a cylinder or a cube. Preferably, the magnet 4 is fixed in the mounting groove 11 with AB glue, and the magnet 4 is a strong magnet.

[0023] Furthermore, the protective layer is made of non-woven fabric, making it easy to disassemble and replace.

[0024] Furthermore, the outer radial wall thickness of the quartz ring 2 does not exceed 5mm, and the thin wall thickness results in a shorter processing time.

[0025] Furthermore, the height of magnet 4 is less than the depth of mounting groove 11 to prevent magnet 4 from scratching the lower surface of quartz ring 2.

[0026] Furthermore, the metal ring 3 is an iron ring, which is relatively inexpensive to manufacture. The outer diameter of the metal ring 3 is smaller than that of the quartz ring 2, and the inner diameter of the metal ring 3 is larger than that of the quartz ring 2, ensuring that the metal ring 3 can be pressed well onto the quartz ring 2, which facilitates subsequent processing of the quartz ring 2.

[0027] See Example 2 Figure 3 , Figure 4 and Figure 5 This embodiment provides a positioning fixture for ring-shaped quartz products. Besides the six rectangular or cylindrical mounting slots 11 evenly arranged radially at the upper end of the positioning plate 1, the outer side of the positioning plate 1 has six through holes that communicate with each of the six mounting slots 11. Adjusting rods 5 are installed in these through holes. The first end of the adjusting rod 5 passes through the through hole and extends into the mounting slot 11, while the second end of the adjusting rod 5 is located on the outer side of the positioning plate 1. The first end of the adjusting rod 5 is detachably mounted with a mounting part 51 with a slot. The length of the adjusting rod 5 extending into the mounting slot 11 is changed by moving the adjusting rod 5 according to the required diameter of the quartz ring 2 to be clamped. The magnet 4 is fixed in the slot. The remaining structure is the same as in Embodiment 1. The adjusting rod 5 and the mounting part 51 can be connected by a detachable connection method such as a plug-in or threaded connection. This structure effectively adjusts the position of the magnet 4, enabling the positioning fixture to clamp quartz rings 2 of different diameters.

[0028] In a preferred embodiment of this invention, the second end of the adjusting rod 5 is provided with a baffle 52 with a diameter larger than that of the through hole, and the height of the mounting part 51 is less than the depth of the mounting groove 11, so that the mounting part 51 will not scratch the lower surface of the quartz ring 2 during the clamping process. The baffle 52 is provided to prevent the adjusting rod 5 from being pushed or pulled, and to limit the maximum length of the adjusting rod 5 extending into the mounting groove 11.

[0029] In a preferred embodiment of this invention, after the adjusting rod 5 is moved to a predetermined position, it is fixed in the mounting groove 11 with fasteners. The fasteners include, but are not limited to, fastening bolts. The predetermined position is when the magnet 4 moves to the required diameter position for clamping the quartz ring 2. The fasteners prevent the adjusting rod 5 from loosening and ensure the stability of the clamping of the quartz ring 2.

[0030] As a preferred embodiment of this example, the upper surface of the plate 1 is provided with a scale value at the edge of the mounting groove 11. The operator can intuitively know the distance moved by the magnet 4 through the scale value, so as to ensure that the position of the magnet 4 can be accurately adjusted according to the diameter of the required clamping quartz ring 2.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
