[0001] This utility model relates to the field of germanium window polishing technology, specifically to a polishing device for processing germanium windows. Background Technology

[0002] Polishing devices are commonly used for mechanical grinding, polishing, and waxing. Their working principle is as follows: an electric motor drives a sponge or wool polishing disc mounted on the machine to rotate at high speed. Due to the combined action of the polishing disc and polishing compound, and the friction against the surface to be polished, paint contamination, oxide layers, and shallow scratches can be removed. The polishing disc typically rotates at around 1500 RPM. 3000r / min, mostly continuously variable transmission, can be adjusted as needed during construction.

[0003] Existing polishing equipment for processing germanium windows has some shortcomings. When polishing germanium windows, it is usually necessary to fix them with clamping components to prevent them from moving and affecting the processing effect. However, because germanium windows are relatively fragile, excessive clamping force may damage them. Also, when polishing germanium windows with a polishing disc, the fixed rotation trajectory between the disc and the window leads to excessive wear on the surface, thus affecting the polishing effect. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a polishing device for processing germanium windows, which solves the problems mentioned in the background art.

[0014] This utility model provides a polishing device for processing germanium windows, which has the following beneficial effects:

[0015] 1. The polishing device for processing germanium windows, before polishing the germanium window, places the germanium window on the surface of the rubber gasket of the air inlet. Through the cooperation of the horn tube and the suction tube, the air in the air inlet is extracted, thereby creating an internal and external pressure difference that can firmly adhere the germanium window to the surface of the polishing table, thus fixing the germanium window in place.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Please refer to Figures 1 to 3. The technical solution provided by this utility model includes a main polishing table 1. An air inlet 18 is provided at the center of the top of the polishing table 1. There are multiple air inlets 18, which are arranged in a ring array. A rubber gasket 16 is fixedly connected to the inner surface of the air inlet 18. The bottom end of the air inlet 18 passes through the polishing table 1 and is connected to a horn tube 19. The air outlet of the horn tube 19 is connected to an air suction pipe 15. The air suction pipe 15 is L-shaped. The air outlet of the air suction pipe 15 passes through the polishing table 1 and is connected to an air pump 14. A fixing frame 13 is fixedly connected to the bottom of one side of the polishing table 1. The air pump 14 is fixedly connected to the fixing frame 13.

[0027] Specifically, before polishing the germanium window, the germanium window is placed on the surface of the air inlet rubber gasket 16 of the air inlet 18. The switch of the air pump 14 is closed, and the air is drawn out of the air inlet 18 through the cooperation of the horn tube 19 and the suction tube 15, thereby reducing the pressure inside the air inlet 18. Since the external pressure is constant, the resulting internal and external pressure difference can firmly adhere the germanium window to the surface of the polishing table 1, thus fixing the germanium window. This avoids the need to use clamping components to fix the germanium window and can fix germanium windows of different diameters.

[0028] Please refer to Figures 1 to 3. The air outlet of the air pump 14 is connected to the air outlet pipe 12. A one-way valve is fixedly connected inside the air outlet pipe 12. The flow direction of the one-way valve is that it can only flow out and cannot flow in.

[0029] Specifically, the air pumped by the air pump 14 can be discharged through the air outlet pipe 12. Since the air outlet pipe 12 is equipped with a one-way valve, and the flow direction of the one-way valve is only outward and not inward, it avoids the difference between the internal and external pressures, which would cause gas backflow and make the pressure difference between the internal and external air inlet 18 the same, thus affecting the fixation of the germanium window.

[0030] Please refer to Figures 1 to 3. The pressure relief port of the horn tube 19 is connected to the pressure relief pipe 17. The air outlet of the pressure relief pipe 17 passes through the polishing table 1. A valve is rotatably connected inside the pressure relief pipe 17. The rotating shaft of the manual stopcock valve extends to the outside of the polishing table 1 and is fixedly connected to the operating handle.

[0031] Specifically, after the germanium window is processed, the valve of the pressure relief pipe 17 is opened. The pressure relief pipe 17 ensures that the internal pressure of the air inlet 18 is equal to the external pressure, which can release the fixation of the germanium window.

[0032] Please refer to Figures 4 to 6. A fixed platform 8 is fixedly connected to one end of the polishing table 1. A support frame 6 is fixedly connected to the top of the front surface of the fixed platform 8. A motor 7 is fixedly connected to the middle of the top of the support frame 6. The bottom end of the output shaft of the motor 7 passes through the support frame 6 and is fixedly connected to a rotating shaft 9. A through hole is opened on one side of the bottom of the rotating shaft 9. An internal thread is opened on the inner wall of the through hole. A fixed shaft 10 is provided on the inner side of the through hole. An external thread is opened on the outer side of the fixed shaft 10. The external thread is threadedly connected to the internal thread. One end of the fixed shaft 10 passes through the rotating shaft 9 and is fixedly connected to a handle. A fixed rod 11 is fixedly connected to the bottom of the surface of the fixed shaft 10. A polishing disc 2 is fixedly connected to the bottom of the fixed rod 11.

[0033] Specifically, after the germanium window is fixed, hold the handle to make it rotate the fixed shaft 10. Since the fixed shaft 10 has an external thread and the rotating shaft 9 has an internal thread, and the internal and external threads are connected by threads, the fixed rod 11 can be used to make the polishing disc 2 deviate from the axis of the rotating shaft 9, so that the edge of the polishing disc 2 is aligned with the edge of the germanium window. Close the switch of the motor 7, and through the rotation of the rotating shaft 9, make the polishing disc 2 move away from the axis of the rotating shaft 9. Since the contact point between the polishing disc 2 and the germanium window processing surface is constantly changing, excessive wear or overheating in some areas is avoided, and dust flow on the germanium window processing surface is promoted, preventing dust from accumulating in one place and affecting the processing of the germanium window.

[0034] Please refer to Figures 4 to 6. A slide rod 5 is fixedly connected to the other side of the bottom end of the surface of the rotating shaft 9. A slider 4 is slidably connected to the surface of the slide rod 5. A connecting rod 3 is fixedly connected to the bottom end of the slider 4. The connecting rod 3 is fixedly connected to the polishing disc 2.

[0035] Specifically, the slider 4, connecting rod 3 and sliding rod 5 are coordinated to keep the polishing disk 2 in place while it rotates, thus preventing the polishing disk 2 from tilting and affecting its polishing of the germanium window.

[0036] During use, before polishing the germanium window, place it on the surface of the rubber gasket 16 at the air inlet 18. Close the switch of the air pump 14. Through the cooperation of the horn tube 19 and the suction tube 15, the air in the air inlet 18 is extracted, reducing the pressure inside the air inlet 18. Since the external pressure is constant, this creates an internal and external pressure difference that firmly adheres the germanium window to the surface of the polishing table 1, thus fixing the germanium window and avoiding the need for clamping components. This method can fix germanium windows of different diameters. The air extracted by the air pump 14 can be discharged through the air outlet tube 12. Because the air outlet tube 12 has a one-way valve inside, and the flow direction of the one-way valve is outward and not inward, it avoids gas backflow caused by different internal and external pressure differences, ensuring that the internal and external pressure differences of the air inlet 18 are the same and affecting the fixation of the germanium window. After the germanium window is processed, open the valve of the pressure relief tube 17 to ensure that the air inlet 18 is fixed. When the internal pressure equals the external pressure, the fixing of the germanium window can be released. After the germanium window is fixed, hold the handle to make it rotate the fixing shaft 10. Since the fixing shaft 10 has an external thread and the rotating shaft 9 has an internal thread, the internal and external threads are connected by threads. Through the cooperation of the fixing rod 11, it can be made to drive the polishing disk 2 away from the axis of the rotating shaft 9, so that the edge of the polishing disk 2 is aligned with the edge of the germanium window. Close the switch of the motor 7, and through the cooperation of the rotating shaft 9, it can drive the polishing disk 2 to move away from the axis of the rotating shaft 9. Since the contact point between the polishing disk 2 and the processing surface of the germanium window is constantly changing, it can avoid excessive wear or overheating in some areas, and can promote the flow of dust on the processing surface of the germanium window, preventing dust from accumulating in one place and affecting the processing of the germanium window. Through the cooperation of the slider 4, the connecting rod 3 and the sliding rod 5, it is kept in place while the polishing disk 2 is rotating, so as to prevent the polishing disk 2 from tilting and affecting the polishing of the germanium window.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
