[0040] The following is combined with Figure 1-3 This application is described in further detail.

[0041] The embodiment of the present application discloses a ring polishing machine.

[0042] Reference Figure 1 , Figure 2 and Figure 3A ring polishing machine includes a frame 1, on which a grinding disc 2 is rotatably arranged. A workpiece ring 3 is movably arranged on the grinding disc 2, and particles to be ground are placed on the grinding disc 2 and located in the workpiece ring 3. A rotation drive mechanism 5 and a lifting mechanism 4 are arranged on the same side of the frame 1, and the rotation drive mechanism 5 is used to drive the workpiece ring 3 to rotate, and the rotation direction of the workpiece ring 3 is opposite to the rotation direction of the grinding disc 2. The lifting mechanism 4 is used to drive the rotation drive mechanism 5 to approach or move away from the frame 1, so that the particles to be ground can be placed in the workpiece ring 3 by lifting the rotation drive mechanism 5. When the rotation drive mechanism 5 approaches the frame 1, the workpiece ring 3 can start to rotate under the action of the rotation drive mechanism 5, and through the rotation of the workpiece ring 3, the workpiece in the workpiece ring 3 can be ground and polished more evenly. In addition, a cooling mechanism 6 is also arranged on the frame 1, which can minimize the influence of the high temperature generated by grinding on the particles to be ground.

[0043] The frame 1 includes a mounting platform 11, which is arranged on the ground through a support column 12, and a circular clearance hole 13 is opened on the mounting platform 11. The grinding disc 2 is rotatably arranged in the clearance hole 13, and the center of the clearance hole 13 is located on the rotation axis of the grinding disc 2. A grinding drive 21 is arranged on the side of the grinding disc 2 close to the ground, and the grinding drive 21 is arranged on the ground, and in this embodiment, the grinding drive 21 is arranged as a reduction motor. The output shaft of the grinding drive 21 is connected to the center of the grinding disc 2, so that the grinding disc 2 can be driven to rotate.

[0044] The lifting mechanism 4 includes a support tube 41, a screw rod 42 and a hand wheel 43. The support tube 41 is cylindrical in shape as a whole and is fixedly mounted above the mounting platform 11 away from the ground, and the axial direction of the support tube 41 is perpendicular to the surface of the mounting platform 11. The length direction of the screw rod 42 is parallel to the axial direction of the support tube 41, and the screw rod 42 is threadedly inserted into the support tube 41 along the axial direction of the support tube 41. The hand wheel 43 is installed at the end of the screw rod 42 away from the support tube 41 to facilitate the rotation of the screw rod 42. A lifting tube 44 is also threadedly sleeved on the screw rod 42, and the lifting tube 44 is located between the hand wheel 43 and the support tube 41. The lifting tube 44 is cylindrical in shape as a whole, and the axis of the lifting tube 44 coincides with the axis of the support tube 41. The lifting tube 44 is connected to a mounting member 46 for mounting the rotation drive mechanism 5 through a connecting rod 45, and the mounting member 46 is located above the workpiece ring 3. In this embodiment, the mounting member 46 is annular, and the center of the mounting member 46 is located on the rotation axis of the grinding disc 2 .

[0045] By turning the hand wheel 43, the lifting cylinder 44 can be moved closer to or farther from the support cylinder 41, thereby driving the rotation drive mechanism 5 closer to or farther from the grinding disc 2. When the lifting cylinder 44 abuts against the support cylinder 41, the rotation drive mechanism 5 can drive the workpiece ring 3 to rotate on the grinding disc 2, thereby grinding and polishing the workpiece in the workpiece ring 3. When the lifting cylinder 44 is away from the support cylinder 41, the rotation drive mechanism 5 moves upward so that the particles to be ground can be placed in the workpiece ring 3.

[0046] The rotation drive mechanism 5 includes a rotation drive member 51 and a driving column 52. In this embodiment, the rotation drive member 51 is configured as a reduction motor, and the rotation drive member 51 is disposed above the mounting member 46. The output shaft of the rotation drive member 51 is located on the side of the rotation drive member 51 close to the workpiece ring 3. One end of the rotation drive member 51 close to the workpiece ring 3 is connected to the end of the connecting rod 45 away from the lifting cylinder 44, and passes through the mounting member 46. A first gear 53 is mounted on the output shaft of the rotation drive member 51, and a second gear 54 meshing with the first gear 53 is disposed on the outer side of the first gear 53. In this embodiment, four second gears 54 are disposed. The number of driving columns 52 and the number of second gears 54 correspond to each other, that is, four driving columns 52 are disposed in this embodiment. The driving column 52 is cylindrical as a whole, and the axial direction of the driving column 52 is perpendicular to the rotation plane of the second gear 54. A rotating shaft 55 is provided at the center of the second gear 54, one end of the rotating shaft 55 is rotatably disposed below the mounting member 46, and the other end of the rotating shaft 55 is installed at the rotation axis of the driving column 52. When the rotating driving member 51 is working, the first gear 53 is driven to rotate, thereby driving the second gear 54 to rotate, and then the rotating shaft 55 can drive multiple driving columns 52 to realize synchronous rotation.

[0047] The bottom of the mounting member 46 is provided with a plurality of mounting rods 56 equidistantly along its own circumferential direction. The mounting rods 56 are rectangular rod-shaped as a whole, and the length direction of the mounting rods 56 is perpendicular to the axial direction of the mounting member 46. In this example, four mounting rods 56 are provided. The end of the mounting rod 56 away from the mounting member 46 is provided with a limit column 57 through a rotating shaft and a rotating bearing. The limit column 57 is cylindrical in shape as a whole, and the axial direction of the limit column 57 is parallel to the axial direction of the driving column 52, and the limit column 57 is located below the mounting rod 56. When the workpiece ring 3 is placed on the grinding disc 2, the outer wall of the workpiece ring 3 abuts against the adjacent driving column 52 and the limit column 57 respectively. When the rotating driving member 51 causes the driving column 52 to rotate, the workpiece ring 3 that can abut against the driving column 52 rotates, and at this time, the limit column 57 plays a limiting role, so that the workpiece ring 3 can rotate on the grinding disc 2 as much as possible, reducing the possibility of the workpiece ring 3 falling off the grinding disc 2. The workpieces in the workpiece ring 3 can be rotated evenly to the greatest extent by the rotating workpiece ring 3. In order to reduce the friction between the driving column 52 and the limiting column 57 and the workpiece ring 3, the outer sides of the driving column 52 and the limiting column 57 are provided with a wear-resistant layer, thereby increasing the service life.

[0048] The cooling mechanism 6 includes a collecting tank 61, a liquid pump 62 and a cooling pipe 63, and the collecting tank 61 is filled with coolant. One end of the cooling pipe 63 is located above the workpiece ring 3, and the mounting ring is provided with mounting holes 461 for fixing the cooling pipe 63 at equal intervals along its own circumferential direction to ensure that the coolant can enter the workpiece ring 3; the other end of the cooling pipe 63 is connected to the liquid pump 62, and the liquid pump 62 is located in the collecting tank 61, and the coolant can drip from the collecting tank 61 into the workpiece ring 3 under the action of the liquid pump 62. A gap is provided between the outer wall of the grinding disc 2 and the inner wall of the yield hole 13 on the mounting platform 11, and the collecting tank 61 is in the shape of a circular ring groove as a whole, and the position of the collecting tank 61 corresponding to the gap is placed below the mounting platform 11, so that the coolant output by the cooling pipe 63 to the workpiece ring 3 can be collected in the collecting tank 61 through the gap; and then the liquid pump 62 is used to make the coolant in the collecting tank 61 return to the top of the workpiece ring 3 to achieve a cooling cycle.

[0049] On this basis, a filter plate 64 is also provided on the side of the collecting tank 61 away from the bottom of the tank, and the end of the cooling pipe 63 away from the workpiece ring 3 is located below the filter plate 64. The powder generated during the grinding and polishing process is easy to enter the collecting tank 61 directly or through the coolant, which may easily cause the liquid pump 62 to be blocked and unusable in the long run. Therefore, by installing the filter plate 64, the powder after grinding and filtering can be filtered, and the normal operation of the cooling mechanism 6 can be guaranteed to the greatest extent. In addition, a guide member 14 is provided around the edge of the yield hole 13 on the mounting table 11, and the guide member 14 is in the shape of a circular ring plate as a whole, so that the coolant can be guided to flow from the gap to the collecting tank 61 as much as possible, reducing the probability of the coolant falling on the mounting table 11, so as to ensure the recycling of the coolant as much as possible.

[0050] The workpiece ring 3 is provided with an extension portion 31 on one side thereof for contacting the grinding disc 2, and a plurality of grooves 32 are equidistantly provided on the side of the extension portion 31 close to the grinding disc 2 along its own circumferential direction, and the plurality of grooves 32 are grooved in a direction away from the workpiece ring 3, so as to discharge the coolant and the powder generated during the grinding process to the outside of the workpiece ring 3. In addition, the extension portion 31 can also protect the workpiece ring 3 from the wear of the grinding disc 2.

[0051] The implementation principle of a ring polishing machine in an embodiment of the present application is: through the driving column 52 and the limiting column 57, the workpiece ring 3 can rotate on the grinding disk 2 under the action of the rotating driving member 51, so that the particles to be ground in the workpiece ring 3 can rotate along with the rotation of the workpiece ring 3, so that the particles to be ground can be ground and polished more evenly; and the cooling mechanism 6 is used to cool the workpiece during the processing to protect the workpiece.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
