[0027] In the present application, the ring blank is first placed on the supporting ring, and then the adjusting rod is moved downward to drive the pressure plate to move downward. At this time, the pressure ring can be used to press the ring blank, and the pressure ring and the pressure plate are rotatably connected, so that the normal rotation of the ring blank will not be affected when the ring blank is pressed. After that, the movable plate can be pushed, and the arc-shaped clamping plate and the clamping groove located above can be used for clamping. Then the L-shaped clamping rod can be released, and the compression spring in a stressed state can drive the limit rod to move downward, so that the L-shaped clamping rod and the fixed plate can be clamped, and the ring blank can be clamped.

[0029] In the present invention, through the limiting mechanism, after the ring blank is placed on the supporting ring, the adjusting rod can be moved downward to drive the pressure plate to move downward. At this time, the ring blank can be pressed by the pressure ring, and the pressure ring and the pressure plate are rotatably connected, so the normal rotation of the ring blank will not be affected when the ring blank is pressed. After that, the movable plate can be pushed, and the arc-shaped clamping plate and the clamping groove located above are used for clamping. Then, the L-shaped clamping rod can be released, and the compression spring in a stressed state can drive the limiting rod to move downward, so that the L-shaped clamping rod and the fixed plate can be clamped, that is, the arc-shaped clamping plate and the adjusting rod can be stably clamped.

[0030] In the present invention, the positions of the inner grinding plate and the outer grinding plate can be adjusted respectively by moving the moving frame and the U-shaped rod respectively through the grinding mechanism, so that the inner grinding plate contacts the inner wall of the ring blank, and the outer grinding plate contacts the outer side of the ring blank. At this time, when the ring blank is rotated, the inner grinding plate and the outer grinding plate can be used to grind the inner wall and the outer wall of the ring blank respectively, so that when the ring blank is ground, the grinding efficiency can be improved;

[0031] In the present invention, the gold powder polished out can float in the water during the polishing of the ring blank through the evaporation mechanism. After the polishing is completed, the electric push rod can be started to drive the sealing plate to move downward, and the water in the processing box will fall into the evaporation tube. Then, the two spiral electric heating rods can be energized to heat the evaporation tube. At this time, the water can be heated by the principle of heat exchange to make the water in an evaporation state until all the water is evaporated. The gold powder in the water can fall on the sealing plate. Then, the electric push rod is started to move the sealing plate out of the evaporation tube. At this time, the gold powder falling on the sealing plate can be collected.

[0032] In the present invention, when grinding and polishing the ring blank, the inner and outer walls of the ring blank can be ground at the same time, so that the work efficiency can be effectively improved, and the ground gold powder can fall into the water, and then the water can be evaporated, so the ground gold powder can be collected in a centralized manner, so the problem of loss can be avoided.

[0051] Example 2

[0052] refer to Figure 2-9 , based on the improvement of Example 1: a processing device, used in the surface treatment process of precious metal jewelry, the processing device specifically includes a grinder and the following mechanisms:

[0053] The grinding machine part includes a base 1, on the top of which a plurality of columns are fixedly installed at equal intervals, and on the tops of these columns a processing box 2 is fixedly installed. Water is provided in the processing box 2, and the main function of the water is to cool down and protect the ring blank 10 when the ring blank 10 is being ground, so as to prevent the ring blank 10 from being damaged by the high temperature generated by the grinding.

[0054] The supporting mechanism part is installed in the processing box 2. Specifically, the supporting mechanism includes a supporting tube 3 fixedly installed on the inner wall of the bottom of the processing box 2, and a plurality of flow holes 6 are evenly spaced on the inner wall of the bottom of the side of the supporting tube 3 to facilitate the passage of water. Through holes corresponding to the supporting tube 3 and the evaporation mechanism mentioned later are opened on the inner wall of the bottom of the processing box 2. A supporting plate 4 is fixedly installed on the top of the supporting tube 3, and a supporting ring 5 is rotatably sleeved on the supporting plate 4, and the ring blank 10 is placed on the top of the supporting ring 5. A power assembly is installed at the bottom of the supporting ring 5, and the bottom of the power assembly extends to the bottom of the processing box 2 and is connected to one side of the bottom of the processing box 2. The power assembly includes a driving motor 7 fixedly installed on one side of the bottom of the processing box 2, and the output shaft of the driving motor 7 extends into the processing box 2 and is fixedly installed with a driving gear 8, and a gear ring 9 is fixedly installed at the bottom of the supporting ring 5, and the driving gear 8 is meshed with the gear ring 9. When the ring blank 10 is placed on the supporting ring 5 and is positioned and pressed by the subsequent limiting mechanism, the driving motor 7 is started to drive the active gear 8 to rotate. At this time, under the meshing transmission action with the gear ring 9, the supporting ring 5 can be driven to rotate, thereby driving the ring blank 10 to rotate, so that the ring blank 10 can be rubbed with the subsequent grinding mechanism to achieve the grinding of the ring blank 10.

[0055] The limiting mechanism part is also installed in the processing box 2, and its top extends to the top of the processing box 2. The limiting mechanism includes two mounting frames 11 symmetrically fixedly installed in the processing box 2, and the tops of these two mounting frames 11 extend to the top of the processing box 2 and are fixedly installed with the same limiting ring 12. An adjusting rod 13 is slidably connected through the limiting ring 12, and a pressure plate 14 is fixedly installed at the bottom end of the adjusting rod 13. A pressure ring 15 is rotatably arranged on the pressure plate 14, and this pressure ring 15 is used to press and limit the ring blank 10. A movable hole 28 is also opened on the pressure plate 14, and the subsequent grinding mechanism will be installed on the top of the pressure plate 14, and one side of the grinding mechanism will extend to the bottom of the pressure ring 15 and be in close contact with the outer side of the ring blank 10, while the other side of the grinding mechanism will pass through the movable hole 28 and contact the inner wall of the ring blank 10. In order to adjust and fix the position of the adjusting rod 13, two card slots 131 are provided on one side of the adjusting rod 13, and a fixed plate 16 is fixedly installed on the top of the mounting frame 11 on one side. A movable plate 17 is slidably connected through the fixed plate 16, and an arc-shaped card plate 18 is fixedly installed on one side of the movable plate 17, and this arc-shaped card plate 18 can be movably clamped with the two card slots 131 respectively. In order to fix the position of the movable plate 17, a limit rod 19 is slidably connected through the movable plate 17, and an L-shaped card rod 20 is fixedly installed on the top of the limit rod 19, and this L-shaped card rod 20 can be clamped with the fixed plate 16. The limit rod 19 is sleeved with a compression spring 21 located below the movable plate 17, and the top and bottom ends of the compression spring 21 are fixedly connected to the bottom of the movable plate 17 and the bottom end of the limit rod 19 respectively. After the ring blank 10 is placed on the support ring 5, the adjusting rod 13 can be moved downward to drive the pressure plate 14 to move downward. At this time, the ring blank 10 can be pressed by the pressure ring 15. Since the pressure ring 15 and the pressure plate 14 are rotatably connected, the normal rotation of the ring blank 10 will not be affected when the ring blank 10 is pressed. After that, the moving plate 17 can be pushed to make the arc-shaped clamping plate 18 be clamped with the clamping groove 131 located above, and then the L-shaped clamping rod 20 can be released. At this time, the compression spring 21 in a stressed state can drive the limit rod 19 to move downward, so that the L-shaped clamping rod 20 is clamped with the fixed plate 16, so that the arc-shaped clamping plate 18 and the adjusting rod 13 can be stably clamped together.

[0056] The grinding mechanism is installed on the pressure plate 14 of the limiting mechanism, and its bottom extends to the bottom of the limiting mechanism. The specific structure and installation method of the grinding mechanism can be designed according to actual needs, as long as the inner and outer walls of the ring blank 10 can be synchronously polished. One side of the grinding mechanism will extend to the bottom of the pressure ring 15 and closely contact the outer side of the ring blank 10, while the other side will pass through the movable hole 28 on the pressure plate 14 and contact the inner wall of the ring blank 10. At the same time, the grinding mechanism will also be movably clamped with a plurality of second clamping holes 33 opened on the pressure plate 14 to facilitate the installation and disassembly of the grinding mechanism.

[0057] The evaporation mechanism is installed at the bottom of the processing box 2 and is connected to the processing box 2. The main function of the evaporation mechanism is to evaporate the water in the processing box 2 to collect the gold powder mixed in the water. The specific structure and working principle of the evaporation mechanism can be designed according to actual needs. For example, heating evaporation can be used to evaporate water into water vapor and separate the gold powder.

[0058] The grinding mechanism mainly includes two limit frames 22, a moving frame 23, an L-shaped mounting plate 24, an inner grinding plate 25, a U-shaped rod 26 and an outer grinding plate 27. The two limit frames 22 are fixedly mounted on the top of the pressure plate 14, and a moving frame 23 is slidably connected between them. An L-shaped mounting plate 24 is fixed on one side of the bottom of the moving frame 23, and the bottom of the L-shaped mounting plate 24 passes through the moving hole 28 on the pressure plate 14 and extends to the bottom of the pressure plate 14. At the bottom of the L-shaped mounting plate 24, an inner grinding plate 25 is fixedly mounted, and the inner grinding plate 25 is in close contact with the inner wall of the ring blank 10.

[0059] A U-shaped rod 26 is slidably connected to the inner wall of one side of the moving frame 23. The U-shaped rod 26 has a plurality of first clamping holes 29 formed at equal intervals, and its bottom end extends to the bottom of the pressing ring 15, and an outer grinding plate 27 is fixedly installed thereon. The outer grinding plate 27 is in close contact with the outer side of the ring blank 10.

[0060] In order to adjust the position of the moving frame 23 and the U-shaped rod 26, a plug-in assembly is installed on the top inner wall of one side of the moving frame 23. The plug-in assembly includes a support plate 30 fixedly installed on the top inner wall of one side of the moving frame 23, and a plug-in rod 31 is slidably connected to the support plate 30. The plug-in rod 31 can be movably clamped with a plurality of first clamping holes 29 and a plurality of second clamping holes 33 respectively. A tension spring 32 is also sleeved on the plug-in rod 31 and is located above the support plate 30. The top and bottom ends of the tension spring 32 are fixedly connected to the top of the plug-in rod 31 and the top of the support plate 30 respectively.

[0061] When in use, the movable frame 23 and the U-shaped rod 26 can be moved respectively to adjust the positions of the inner grinding plate 25 and the outer grinding plate 27 so that they are in close contact with the inner wall and the outer wall of the ring blank 10 respectively. At this time, when the ring blank 10 rotates, the inner grinding plate 25 and the outer grinding plate 27 can be used to grind the inner wall and the outer wall of the ring blank 10 respectively. After the adjustment is completed, the insertion rod 31 can be released, and the tension spring 32 in the stressed state will drive the insertion rod 31 to move downward, so that the insertion rod 31 passes through the corresponding first clamping hole 29 and the second clamping hole 33 respectively, thereby positioning the movable frame 23 and the U-shaped rod 26.

[0062] Example 3

[0063] Reference Figure 3 , an improvement on the basis of Example 2: a processing device, the evaporation mechanism mainly includes components such as an evaporation tube 34, an electric push rod 35, a sealing disk 36, a protective tube 37 and a spiral electric heating rod 38. The evaporation tube 34 is fixedly installed at the bottom of the processing box 2 and is connected to the through hole. On the evaporation tube 34, a protective tube 37 is fixedly provided, and two spiral electric heating rods 38 are fixedly installed in the protective tube 37. An electric push rod 35 is fixedly installed on the top of the base 1, and the output shaft of the electric push rod 35 extends into the evaporation tube 34, and a sealing disk 36 is fixedly installed. This sealing disk 36 is sealed and fitted with the inner wall of the evaporation tube 34.

[0064] During the polishing process of the ring blank 10, the polished gold powder will float in the water. After the polishing is completed, the electric push rod 35 can be started to drive the sealing plate 36 to move downward. At this time, the water in the processing box 2 will fall into the evaporation tube 34. Then, the two spiral electric heating rods 38 can be energized to heat the evaporation tube 34. At this time, the water can be heated by the principle of heat exchange to make the water in an evaporation state. When all the water is evaporated, the gold powder in the water will fall on the sealing plate 36. After that, the electric push rod 35 can be started again to move the sealing plate 36 out of the evaporation tube 34, and the gold powder that falls on the sealing plate 36 can be collected.

[0065] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 7 and the spiral electric heating rod 38 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
