[0037] The staff places the workpiece to be polished on the top of the support frame 9, and drives the first movable plate 17 to move up through the first hydraulic telescopic rod 18. The first movable plate 17 drives the support plate 12 and the lifting frame 7 to move up through the compression spring 20 and the support plate 14, so that the lifting frame 7 drives the support frame 9 through the third rotating shaft 8 to drive the workpiece to be polished and the bottom end of the pressing frame 6 to contact. As the first movable plate 17 continues to move upward, the distance between the first movable plate 17 and the support plate 14 becomes smaller, and the compression spring 20 is in a compressed state. The compression spring 20 applies pressure to the support plate 14 so that the first rolling ball 16 is elastically pressed on the bottom of the support plate 12, so that the workpiece to be polished is elastically clamped between the support frame 9 and the pressing frame 6.

The support plate 14 moves, and the first rolling ball 16 rolls at the bottom of the support plate 12.

A plurality of baffles 42 are fixedly connected to the second support column 30, and the number of the second avoidance holes 41, the baffles 42 and the second support column 30 is consistent, and the baffles 42 pass through the second avoidance holes 41. At least two mounting frames 45 are fixedly connected to the top of the control box 2, and the mounting frames 45 are fixedly installed with a second hydraulic telescopic rod 46. The telescopic end of the second hydraulic telescopic rod 46 is fixedly connected with a pressing plate 47, and the bottom of the pressing plate 47 is in contact with the top of the support ring 40. The polishing unit includes a third servo motor 48 fixedly installed on the base 1, and the output end of the third servo motor 48 is fixedly connected with a polishing wheel 49 for polishing the workpiece to be polished;

[0039] The damping plate 34 is driven to rotate by the second servo motor 33, and the damping plate 34 drives the damping plate 32 and the paddle plate 31 to rotate synchronously through friction, and the paddle plate 31 drives the second rolling ball 39 to roll on the guide ring 35, and the paddle plate 31 rotates relative to the guide ring 35. Through the design of the guide ring 35, the fixing plate 36, the guide hole 37, the second accommodating groove 38 and the second rolling ball 39, the paddle plate 31 and the damping plate 32 can rotate smoothly relative to the control box 2, and the paddle plate 31 pushes the second support column 30 and the second movable plate 24 to move synchronously, and the second movable plate 24 drives the second guide column 28 to move relative to the support portion 27, the tension spring 29 is in a tensioned state, and the second movable plate 24 pushes the first support column 26 to slide in the slide groove 25 The first support column 26 drives the swing plate 3 to rotate around the first rotating shaft 4, and the polishing wheel 49 is driven to rotate by the third servo motor 48. When the workpiece to be polished, which is clamped and fixed by the clamped self-rotating assembly, contacts the polishing wheel 49, the workpiece to be polished is polished by the polishing wheel 49. When the force of the workpiece to be polished pressing on the polishing wheel 49 reaches a preset value, as the damping disc 34 continues to rotate, the damping disc 34 cannot drive the damping plate 32 and the paddle plate 31 to move by friction, ensuring that the force of the polishing workpiece pressing on the polishing wheel 49 is at a preset value. As the polishing continues, the diameter of the workpiece to be polished becomes smaller, and the swing plate 3 slowly rotates around the first rotating shaft 4. When the second support column 30 contacts the corresponding baffle plate 42, the second support column 30 contacts the corresponding baffle plate 42. When the second support column 30 and the second movable plate 24 stop moving, the swing plate 3 stops rotating around the first rotating shaft 4 to avoid over-polishing, which causes the diameter of the workpiece to be polished to be less than the preset value. When the polishing of the workpiece to be polished is completed, the damping plate 34 is driven to rotate in the opposite direction by the second servo motor 33. The damping plate 34 drives the damping plate 32 and the paddle plate 31 to rotate in the opposite direction through friction, so that the paddle plate 31 no longer presses the second support column 30. The tension spring 29 drives the second movable plate 24 and the second guide column 28 to slide in the opposite direction relative to the support portion 27, so that the second movable plate 24 is reset to the initial position, and the second movable plate 24 drives the first support column 26 to slide in the opposite direction in the slide groove 25. The second movable plate 24 is driven by the first support column 26 to slide in the opposite direction in the slide groove 25. The column 26 drives the swing plate 3 to rotate in the opposite direction around the first rotating shaft 4, so that the swing plate 3 is reset to the initial position relative to the control box 2. The pressing plate 47 is driven to move upward by the second hydraulic telescopic rod 46, so that the pressing plate 47 no longer presses the support ring 40, thereby releasing the limitation on the position of the support ring 40. The staff drives the support ring 40 to rotate relative to the control box 2, and the guide block 44 slides in the guide groove 43. The support ring 40 drives the baffle 42 to rotate, so as to adjust the initial position of the baffle 42. After the position of the baffle 42 is adjusted, the pressing plate 47 is driven to move downward by the second hydraulic telescopic rod 46, so that the pressing plate 47 presses the top of the support ring 40 again, so that the support ring 40 and the baffle 42 are fixed relative to the control box 2.

[0040] A method for polishing a large-aspect-ratio ceramic window of this embodiment uses the large-aspect-ratio ceramic window polishing device as described above, comprising the following steps:

[0041] Step 1: clamp and fix a plurality of workpieces to be polished by a clamping self-rotating assembly, and drive the swing plate 3 to rotate around the first rotating shaft 4 by turning the adjustment structure to control the distance between the plurality of workpieces to be polished and the polishing unit;

[0042] Step 2: After the workpiece to be polished moves to a preset position, the side wall of the workpiece to be polished is polished by the polishing unit, and the clamping rotation assembly drives the workpiece to be polished to rotate, so that the polishing unit polishes different positions on the side wall of the workpiece to be polished;

[0043] Step 3: When polishing is completed, the swing plate 3 is driven to return to the initial position relative to the first rotating shaft 4 by toggling the adjustment structure, the clamping and rotating assembly releases the clamping and fixing of the workpiece to be polished, and the staff removes the processed workpiece to be polished.

[0044] Working principle: During operation, a plurality of workpieces to be polished are clamped and fixed by the clamping self-rotating assembly, and the swing plate 3 is driven to rotate around the first rotating shaft 4 by turning the adjustment structure, so that the workpieces to be polished clamped and fixed by the clamping self-rotating assembly rotate around the first rotating shaft 4, and the distance between the plurality of workpieces to be polished and the polishing unit is controlled at the same time. When the workpieces to be polished move to the preset position, the side wall of the workpieces to be polished is polished by the polishing unit, and the clamping self-rotating assembly drives the workpieces to be polished to rotate, so that the polishing unit polishes different positions on the side wall of the workpieces to be polished. When the polishing is completed, the swing plate 3 is driven to reset to the initial position relative to the first rotating shaft 4 by turning the adjustment structure, and the clamping self-rotating assembly releases the clamping and fixing of the workpieces to be polished. The staff removes the processed workpieces to be polished, and the side walls of multiple workpieces to be polished can be polished at the same time, which improves the polishing efficiency and is convenient for practical use.

[0045] The staff places the workpiece to be polished on the top of the support frame 9, and drives the first movable plate 17 to move up through the first hydraulic telescopic rod 18. The first movable plate 17 drives the support plate 12 and the lifting frame 7 to move up through the compression spring 20 and the support plate 14, so that the lifting frame 7 drives the support frame 9 through the third rotating shaft 8 to drive the workpiece to be polished and the bottom end of the pressing frame 6 to contact. As the first movable plate 17 continues to move upward, the distance between the first movable plate 17 and the support plate 14 becomes smaller, and the compression spring 20 is in a compressed state. The compression spring 20 applies pressure to the support plate 14 so that the first rolling ball 16 is elastically pressed on the bottom of the support plate 12, so that the workpiece to be polished is elastically clamped between the support frame 9 and the pressing frame 6. When the adjustment structure is driven to drive the swing plate 3 to rotate around the first rotating shaft 4, the swing plate 3 drives the lifting frame 7 and the support plate 12 to contact each other. The support plate 14 moves, and the first rolling ball 16 rolls at the bottom of the support plate 12. The design of the first rolling ball 16 reduces the resistance of the swing plate 3, the lifting frame 7 and the support plate 12 when they move relative to the support plate 14, and the swing plate 3 drives the first gear 10 to rotate around the second gear 11 through the second rotating shaft 5. When it is necessary to drive the pressing frame 6 and the second rotating shaft 5 to rotate, the first servo motor 21 drives the fixing frame 22 and the ring gear 23 to rotate, and the ring gear 23 drives the first gear 10 and the second rotating shaft 5 to rotate through the second gear 11. The second rotating shaft 5 can drive the pressing frame 6, the workpiece to be polished, the support frame 9 and the third rotating shaft 8 to rotate relative to the lifting frame 7 and the swing plate 3. When the swing plate 3 rotates relative to the first rotating shaft 4, it does not affect the pressing frame 6 and the support frame 9 clamping the workpiece to be polished, and does not affect the self-rotation of the pressing frame 6, the support frame 9 and the workpiece to be polished.

[0046] The damping plate 34 is driven to rotate by the second servo motor 33, and the damping plate 34 drives the damping plate 32 and the paddle plate 31 to rotate synchronously through friction, and the paddle plate 31 drives the second rolling ball 39 to roll on the guide ring 35, and the paddle plate 31 rotates relative to the guide ring 35. Through the design of the guide ring 35, the fixing plate 36, the guide hole 37, the second accommodating groove 38 and the second rolling ball 39, the paddle plate 31 and the damping plate 32 can rotate smoothly relative to the control box 2, and the paddle plate 31 pushes the second support column 30 and the second movable plate 24 to move synchronously, and the second movable plate 24 drives the second guide column 28 to move relative to the support portion 27, the tension spring 29 is in a tensioned state, and the second movable plate 24 pushes the first support column 26 to slide in the slide groove 25 The first support column 26 drives the swing plate 3 to rotate around the first rotating shaft 4, and the polishing wheel 49 is driven to rotate by the third servo motor 48. When the workpiece to be polished, which is clamped and fixed by the clamped self-rotating assembly, contacts the polishing wheel 49, the workpiece to be polished is polished by the polishing wheel 49. When the force of the workpiece to be polished pressing on the polishing wheel 49 reaches a preset value, as the damping disc 34 continues to rotate, the damping disc 34 cannot drive the damping plate 32 and the paddle plate 31 to move by friction, ensuring that the force of the polishing workpiece pressing on the polishing wheel 49 is at a preset value. As the polishing continues, the diameter of the workpiece to be polished becomes smaller, and the swing plate 3 slowly rotates around the first rotating shaft 4. When the second support column 30 contacts the corresponding baffle plate 42, the second support column 30 contacts the corresponding baffle plate 42. When the second support column 30 and the second movable plate 24 stop moving, the swing plate 3 stops rotating around the first rotating shaft 4 to avoid over-polishing, which causes the diameter of the workpiece to be polished to be less than the preset value. When the polishing of the workpiece to be polished is completed, the damping plate 34 is driven to rotate in the opposite direction by the second servo motor 33. The damping plate 34 drives the damping plate 32 and the paddle plate 31 to rotate in the opposite direction through friction, so that the paddle plate 31 no longer presses the second support column 30. The tension spring 29 drives the second movable plate 24 and the second guide column 28 to slide in the opposite direction relative to the support portion 27, so that the second movable plate 24 is reset to the initial position, and the second movable plate 24 drives the first support column 26 to slide in the opposite direction in the slide groove 25. The second movable plate 24 is driven by the first support column 26 to slide in the opposite direction in the slide groove 25. The column 26 drives the swing plate 3 to rotate in the opposite direction around the first rotating shaft 4, so that the swing plate 3 is reset to the initial position relative to the control box 2. The pressing plate 47 is driven to move upward by the second hydraulic telescopic rod 46, so that the pressing plate 47 no longer presses the support ring 40, thereby releasing the limitation on the position of the support ring 40. The staff drives the support ring 40 to rotate relative to the control box 2, and the guide block 44 slides in the guide groove 43. The support ring 40 drives the baffle 42 to rotate, so as to adjust the initial position of the baffle 42. After the position of the baffle 42 is adjusted, the pressing plate 47 is driven to move downward by the second hydraulic telescopic rod 46, so that the pressing plate 47 presses the top of the support ring 40 again, so that the support ring 40 and the baffle 42 are fixed relative to the control box 2.
