Description

Technical Field

[0001] This utility model relates to the field of ultra-precision machining technology, specifically a flexible airbag adaptive curved surface polishing device. Background Technology

[0002] The flexible airbag adaptive surface polishing device is mainly used for the precision machining of optical components, especially for complex geometries such as aspherical and free-form surfaces. The main axis of airbag rotation maintains a fixed angle with the normal of the polishing dwell point. By controlling the airbag rotation speed, air pressure and dwell time, a Gaussian-like removal function is generated to achieve deterministic material removal.

[0003] In the polishing process of optical components, the polishing slurry removes material through the synergistic effect of chemical corrosion and mechanical friction, which is a key element in ensuring processing accuracy and surface quality. However, in current processes, the polishing slurry is mostly disposed of by direct waste or end-of-pipe treatment, which not only wastes resources but also poses a potential pollution risk to the surrounding water bodies, soil, and other ecological environments due to the residual heavy metal ions, acidic and alkaline substances, and nanoscale suspended matter in the polishing slurry, thus violating the sustainable development concepts of circular economy and green manufacturing. Therefore, those skilled in the art have provided a flexible airbag adaptive curved surface polishing device to solve the problems mentioned in the background art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This utility model provides a technical solution:

[0029] A flexible airbag adaptive curved surface polishing device, comprising:

[0030] The processing box 1 is equipped with a first inspection door 40 and a second inspection door 41. The processing box 1 is equipped with a placement rack 2. The placement rack 2 is equipped with a clamping assembly. The clamping assembly includes two side plates 15, two electric push rods 16 and two clamping plates 17. The two side plates 15 are fixedly connected to the placement rack 2. The electric push rods 16 are fixedly connected to the side plates 15, and the output end of the electric push rods 16 is fixedly connected to the clamping plates 17.

[0031] Open the first inspection door 40 on the processing box 1, place the workpiece to be polished on the placement rack 2 inside the processing box 1, and the controller 42 starts the electric push rod 16. The electric push rod 16 pushes the clamping plate 17. Since the electric push rod 16 is fixedly connected to the side plate 15, and the side plate 15 is fixed on the placement rack 2, the two clamping plates 17 will move towards each other, thereby firmly clamping the workpiece.

[0032] A drain cover 3 is fixedly installed inside the processing box 1. The drain cover 3 is connected to a sedimentation box 4. The sedimentation box 4 is connected to a filter box 5 through a connecting assembly. The filter box 5 is connected to an oxidation box 6 through a connecting assembly. The oxidation box 6 is connected to a regulating box 7 through a connecting assembly. The regulating box 7 is connected to two regulating pipes 8 through a circulation assembly. The circulation assembly includes a circulation pipe 27 and a circulation pump 28. The two ends of the circulation pipe 27 are connected to the regulating box 7 and the regulating pipe 8 respectively. The circulation pump 28 is connected to the circulation pipe 27. Nozzles 9 are installed on the two regulating pipes 8.

[0033] Among them, the sedimentation tank 4, oxidation tank 6 and regulating tank 7 are all equipped with feeding tanks 18. The feeding tanks 18 are connected to the sedimentation tank 4, oxidation tank 6 and regulating tank 7 respectively by a discharge pipe 19. The discharge pipe 19 is equipped with an electric control valve 20. The feeding tank 18 is equipped with a feed pipe 21. The feed pipe 21 is threaded with a baffle 22.

[0034] Furthermore, the connecting assembly includes a water pump 23, a first connecting pipe 24 and a second connecting pipe 25. One end of the first connecting pipe 24 is connected to the sedimentation tank 4, the filter tank 5 and the oxidation tank 6 respectively, and the other end of the first connecting pipe 24 is connected to the water pump 23. One end of the second connecting pipe 25 is connected to the water pump 23, and the other end of the second connecting pipe 25 is connected to the filter tank 5, the oxidation tank 6 and the regulating tank 7 respectively. Several filter screens 43 are installed in the filter tank 5, and a reverse osmosis membrane filter element 26 is connected to the first connecting pipe 24 connected to the oxidation tank 6.

[0035] The polishing liquid containing impurities generated during the polishing process flows into the drain hood 3 and then into the sedimentation tank 4. In the sedimentation tank 4, the controller 42 adjusts the electric control valve 20, and the precipitant in the feed tank 18 enters the sedimentation tank 4 through the discharge pipe 19. The precipitant reacts with the polishing liquid to initially reduce the concentration of suspended solids.

[0036] The controller 42 controls the water pump 23 to start, and transports the polishing liquid after preliminary treatment in the sedimentation tank 4 to the water pump 23 through the first connecting pipe 24. The water pump 23 then transports it to the filter box 5 through the second connecting pipe 25. The filter screens 43 in the filter box 5 adopt the gradient density filtration method, with the filter holes decreasing in size, which can effectively reduce the risk of clogging in subsequent processing stages.

[0037] The water pump 23 delivers the filtered polishing liquid to the oxidation tank 6 through the first connecting pipe 24 and the second connecting pipe 25. In the oxidation tank 6, the controller 42 adjusts the electric control valve 20. The hydrogen peroxide in the feeding tank 18 enters the oxidation tank 6 through the discharge pipe 19. The hydrogen peroxide reacts with the oxidizing impurities to generate large particle precipitates.

[0038] The controller 42 controls the water pump 23, which pumps the polishing liquid that has been precipitated again into the regulating tank 7 through the first connecting pipe 24 and the second connecting pipe 25. When the polishing liquid is pumped into the regulating tank 7, the reverse osmosis membrane filter element 26 on the first connecting pipe 24 connected to the oxidation tank 6 will further filter impurities. The regulating tank 7 is equipped with a pH value detection sensor, an abrasive additive concentration sensor and a deionized water monitoring sensor, which can detect the pH value of the liquid in real time and the content of abrasive and deionized water. Then the controller 42 adjusts the electric control valve 20, and the phosphoric acid or sodium hydroxide solution in the feeding tank 18 enters the regulating tank 7 through the discharge pipe 19, which precisely controls the pH value of the polishing liquid to the acidity and alkalinity range required by the process. The concentration and performance indicators of the polishing liquid are restored by the cerium oxide abrasive and specific additives added in the above operation.

[0039] The treated polishing slurry is returned to the polishing work area via the circulation pump 28 and circulation pipe 27 of the circulation component, through the regulating pipe 8 and nozzle 9, thus realizing the recycling of the polishing slurry.

[0040] A servo electric cylinder 10 is installed on the processing box 1. The output end of the servo electric cylinder 10 is connected to a first mounting frame 11 through an adjustment mechanism. The adjustment mechanism includes a second mounting frame 29, a first drive motor 30, an L-shaped plate 31, a second drive motor 32, and a rotating rod 33. The output end of the servo electric cylinder 10 is connected to the second mounting frame 29. The first drive motor 30 is installed inside the second mounting frame 29, and its output end is connected to the L-shaped plate 31. The second mounting frame 29 is rotatably connected to the L-shaped plate 31. The second drive motor 32 is installed on the L-shaped plate 31. The first mounting frame 11 is rotatably connected to the L-shaped plate 31 through the rotating rod 33, and the output end of the second drive motor 32 is connected to the rotating rod 33. A servo motor 12 is installed inside the first mounting frame 11, and its output end is connected to a rotating rod 13.

[0041] The controller 42 controls the servo cylinder 10, causing the output of the servo cylinder 10 to move the first mounting frame 11 to a suitable position. If the grinding angle needs to be adjusted, the controller 42 can control the first drive motor 30 and the second drive motor 32 in the adjustment mechanism respectively. The first drive motor 30 drives the L-shaped plate to rotate. Since the second mounting frame 29 is rotatably connected to the L-shaped plate, angle adjustment in one direction can be achieved. The second drive motor 32 drives the rotating rod 33 to rotate. The first mounting frame 11 is rotatably connected to the L-shaped plate through the rotating rod 33, thereby achieving angle adjustment in another direction, ultimately enabling the grinding head 14 to reach a suitable grinding angle.

[0042] During grinding, the controller 42 starts the servo motor 12, which drives the rotating rod 13 to rotate, thereby causing the grinding head 14 to rotate and polish the workpiece.

[0043] The rotating rod 13 is connected to the grinding head 14 via a locking mechanism. The locking mechanism includes a connecting rod 34, a threaded ring 35, a fixing ring 36, and two locking rods 37. The two locking rods 37 are fixedly connected to the connecting rod 34, the connecting rod 34 is fixedly connected to the grinding head 14, and the threaded ring 35 is fixedly connected to the connecting rod 34. The rotating rod 13 has a moving groove 38, and a locking groove 39 communicating with the moving groove 38 is opened on one side of the moving groove 38. The locking rods 37 are locked in the locking groove 39. The fixing ring 36 is threadedly connected to the threaded ring 35, and the fixing ring 36 is in contact with the locking rods 37.

[0044] When installing the grinding head 14, align the locking rod 37 on the connecting rod 34 with the moving groove 38 on the rotating rod 13 and insert it. Then, lock the locking rod 37 into the locking groove 39. Then, thread the fixing ring 36 and the threaded ring 35 together until the fixing ring 36 and the locking rod 37 are in close contact, thus completing the installation of the grinding head 14.

[0045] When disassembling the grinding head 14, rotate the retaining ring 36 to move it away from the locking rod 37, move the connecting rod 34 upward to move the locking rod 37 out of the locking groove 39, then rotate the connecting rod 34 to move it to the moving groove 38, and then pull the locking rod 37 out of the moving groove 38 to disassemble the grinding head 14.

[0046] In the above embodiment, a controller 42 is installed on the processing box 1. The controller 42 is electrically connected to the servo cylinder 10, the servo motor 12, the electric control valve 20, the water pump 23, the circulating pump 28, the first drive motor 30, and the second drive motor 32.
