Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and in particular to a processing equipment for improving the precision of infrared germanium glass aspherical surfaces. Background Technology

[0002] Infrared germanium glass, as a material of great importance in the field of infrared optics, is widely used in military and defense and civilian fields due to its good optical transmittance, high refractive index and chemical stability in the infrared band. Compared with traditional spherical elements, aspherical optical elements can effectively correct aberrations and improve image quality, and can also reduce the number of lenses to achieve lightweight and miniaturization of optical systems. An infrared germanium glass aspherical precision enhancement processing equipment is used to process infrared germanium glass into aspherical optical elements to meet the needs of various fields for high-precision and high-performance infrared optical elements.

[0003] A search revealed CN216803116U, which discloses a high-precision aspherical optical lens fixture. The fixture includes a placement box, a motor fixedly connected to the left side of the placement box, and a lead screw fixedly connected to the output end of the motor. The lead screw extends through the right side of the inner wall of the placement box and is fixedly connected to the placement box via a bearing. Two sliders are fitted onto the surface of the lead screw, and a connecting block is fixedly connected to the top of each slider. The top of the connecting block extends through to the top of the placement box and is fixedly connected to a T-shaped box. This invention, by incorporating a placement box, motor, lead screw, sliders, connecting block, T-shaped box, vertical plate, diagonal rod, L-shaped clamping plate, short rod, and rectangular block, solves the problems of existing fixtures being too cumbersome to hold and fix automatically, and most fixtures on the market requiring manual clamping, resulting in excessively long fixing times and overly complicated steps, thus reducing the processing efficiency of optical lenses.

[0004] The positioning fixtures or clamping devices in existing processing equipment cannot simultaneously meet the fixing requirements of infrared germanium glass of various shapes and sizes. Special clamps need to be customized for glass of different shapes and sizes, which is cumbersome and costly. For irregularly shaped infrared germanium glass, traditional clamping methods are difficult to fix stably due to the irregular shape, which causes the glass position to change during processing and affects the processing accuracy. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision improvement processing equipment for infrared germanium glass aspherical surfaces, aiming to improve the problem that existing processing equipment is difficult to adapt to infrared germanium glass of different specifications, which affects the processing accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision improvement processing device for infrared germanium glass aspherical surfaces, comprising a base plate, three slide rails fixedly connected to the top of the base plate, sliding blocks slidably connected to the top of each of the three slide rails, clamping members fixedly connected to the top of each of the three sliding blocks, rotating rods rotatably connected to adjacent sides of each of the three sliding blocks, rotating members rotatably connected between adjacent sides of the three rotating rods, the lower surface of the rotating members rotatably connected to the base plate, a cylinder fixedly connected to the rear side of the top of the base plate, the output end of the cylinder fixedly connected to an adjacent sliding block, and a switching assembly provided on the top of the base plate for switching different cleaning media.

[0007] Furthermore, the switching component includes a connector, which is fixedly connected to the base plate. A rotating column is rotatably connected to the inner diameter of the connector. A worm gear is fixedly connected to the outer surface of the rotating column. A worm is meshed with the rear side of the worm gear. A conveying groove is provided inside the rotating column.

[0008] Furthermore, a motor is fixedly connected to the top of the base plate, and the output end of the motor is fixedly disposed between the worm gear and the base plate.

[0009] Furthermore, a water pump is fixedly connected to the top of the clamping member on the rear side, a bellows is fixedly provided at the input end of the water pump, a rotary joint is fixedly connected to the bottom end of the bellows, and the bottom end of the rotary joint is fixedly connected to the rotating column.

[0010] Furthermore, an infusion pipe is fixedly installed at the output end of the water pump, and a nozzle is fixedly connected to the front end of the infusion pipe. The nozzle is fixedly connected to the clamping member on the rear side.

[0011] Furthermore, three water tanks are fixedly connected to the top right side of the base plate, and all three water tanks are fixedly connected to the connector.

[0012] Furthermore, a placement platform is provided between the three clamping members, and the placement platform is fixedly connected to the base plate.

[0013] Furthermore, the three clamping members are made of polytetrafluoroethylene on one side of each other, and the top of the placement platform is made of granite.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the cylinder drives the sliding block on the rear side to slide. When the sliding block on the rear side slides, it drives the rotating rod to move, thereby driving the rotating part and the other two sliding blocks to move. This enables the three clamping parts to clamp and fix the components on the placement table, adapting to the fixing requirements of infrared germanium glass of different sizes and improving the versatility of the equipment.

[0016] 2. In this utility model, the worm gear is driven by a motor to rotate, which in turn drives the worm wheel and the rotating column to rotate, so that the conveying trough faces different water tanks, thereby enabling the water pump to extract liquid from different water tanks. In the processing of infrared germanium glass aspherical surfaces, this enables rapid response to the needs of different stages requiring different liquids for cooling, cleaning or chemical treatment, providing strong support for complex processing procedures.

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3An embodiment of this utility model provides an infrared germanium glass aspherical surface precision improvement processing device, including a base plate 1, three slide rails 2 fixedly connected to the top of the base plate 1, sliding blocks 3 slidably connected to the top of each of the three slide rails 2, clamping parts 4 fixedly connected to the top of each of the three sliding blocks 3, rotating rods 14 rotatably connected to adjacent sides of each of the three sliding blocks 3, rotating parts 15 rotatably connected between adjacent sides of the three rotating rods 14, the lower surface of the rotating parts 15 rotatably connected to the base plate 1, a cylinder 6 fixedly connected to the rear side of the top of the base plate 1, the output end of the cylinder 6 fixedly connected to the adjacent sliding block 3, and a switching component provided on the top of the base plate 1 for switching different cleaning media.

[0025] Specifically, when using this device, the infrared germanium glass is first placed on the placement platform 5. Then, the cylinder 6 is activated to push the rear sliding block 3 to slide on the slide rail 2. The sliding of the rear sliding block 3 causes the rotating rod 14 and rotating component 15 connected to it to rotate. The rotating component 15 causes the other two rotating rods 14 to move, which in turn causes the other two sliding blocks 3 to slide on the slide rail 2. Finally, the clamping component 4 fixedly connected to the top of the three sliding blocks 3 moves synchronously towards the middle, thereby clamping and fixing the infrared germanium glass of the size on the placement platform 5.

[0026] Reference Figure 3 and Figure 4 The switching component includes a connector 18, which is fixedly connected to the base plate 1. A rotating column 19 is rotatably connected to the inner diameter of the connector 18. A worm gear 12 is fixedly connected to the outer surface of the rotating column 19. A worm 17 is meshed with the rear side of the worm gear 12. A conveying groove 20 is opened inside the rotating column 19.

[0027] Specifically, when the processing reaches a stage where different liquids are needed to meet the requirements of cooling, cleaning, or chemical treatment, the user turns on the motor 16. The motor 16 drives the worm gear 17 to rotate, and the worm gear 17 drives the meshing worm wheel 12 to rotate. The worm wheel 12 drives the fixedly connected rotating column 19 to rotate within the inner diameter of the connector 18. The rotation of the rotating column 19 causes the conveying groove 20 inside it to rotate and face different water tanks 13. At this time, the user turns on the water pump 7, and the water pump 7 draws out the required liquid from the corresponding water tank 13 through the liquid delivery pipe 8 connected to the water tank 13 to meet the different liquid requirements of different stages of infrared germanium glass aspherical surface processing.

[0028] Reference Figure 3 A motor 16 is fixedly connected to the top of the base plate 1, and the output end of the motor 16 is fixedly connected to the worm gear 17.

[0029] Specifically, the motor 16 drives the worm gear 17 to rotate, and then through the meshing transmission between the worm gear 17 and the worm wheel 12, the rotation of the rotating column 19 and the conveying trough 20 is realized, ultimately satisfying the purpose of switching different liquids in the water tank 13 to meet the needs of different stages of infrared germanium glass aspherical surface processing.

[0030] Reference Figure 3 A water pump 7 is fixedly connected to the top of the clamping part 4 on the rear side. A bellows 10 is fixedly installed at the input end of the water pump 7. A rotary joint 11 is fixedly connected to the bottom end of the bellows 10. The bottom end of the rotary joint 11 is fixedly connected to the rotating column 19.

[0031] Specifically, the corrugated pipe 10 is flexible and bendable, and can maintain its connection with the water pump 7 even when the rotating column 19 rotates and changes position, ensuring that the liquid delivery is not affected by the rotation. The rotary joint 11 can ensure stable liquid delivery while allowing the rotating column 19 to rotate smoothly. The rotary joint 11 guides the liquid flowing out of the delivery trough 20 in the rotating column 19 to the corrugated pipe 10 and delivers it upward through the water pump 7, thereby realizing the effective supply of liquid from different water tanks 13 to the processing position.

[0032] Reference Figure 3 The output end of the water pump 7 is fixedly equipped with an infusion pipe 8, and the front end of the infusion pipe 8 is fixedly connected to a nozzle 9. The nozzle 9 is fixedly connected to the clamping part 4 on the rear side.

[0033] Specifically, the infusion pipe 8 delivers the liquid drawn by the water pump 7 to the nozzle 9, and the nozzle 9 sprays out the liquid delivered by the infusion pipe 8 to achieve cooling, cleaning or chemical treatment of the infrared germanium glass.

[0034] Reference Figure 3 Three water tanks 13 are fixedly connected to the top right side of the base plate 1, and all three water tanks 13 are fixedly connected to the connector 18.

[0035] Specifically, three water tanks 13 are fixedly connected to the top right side of the base plate 1, providing multiple liquid sources for the entire processing. All three water tanks 13 are connected to the connector 18, so that the rotating column 19 and the conveying trough 20 can accurately correspond to different water tanks 13, realizing the selection and delivery of liquids from different water tanks 13. One water tank 13 contains deionized water, which is pure and free of impurities and can effectively remove the heat generated during processing, thereby reducing the temperature of the infrared germanium glass during processing and preventing the processing accuracy from being affected by excessive temperature. Another water tank 13 contains an alkaline cleaning solution containing surfactants. This cleaning solution has good dissolving and dispersing ability for oil stains and debris, and is used to clean debris, oil stains and various impurities remaining on the glass surface during processing, ensuring the cleanliness of the glass surface. The third water tank 13 contains a hydrofluoric acid solution, which can chemically react with germanium glass to perform etching chemical treatment on the infrared germanium glass, thereby changing its surface microstructure or dimensional accuracy, thus meeting the operational requirements for cooling, cleaning or chemical treatment of infrared germanium glass.

[0036] Reference Figure 1 A placement platform 5 is provided between the three clamping parts 4, and the placement platform 5 is fixedly connected to the base plate 1.

[0037] Specifically, the placement table 5 provides a placement position for the infrared germanium glass, giving it a stable supporting foundation during processing and ensuring that the glass is in a suitable processing area.

[0038] Reference Figure 1 The three clamping parts 4 are made of polytetrafluoroethylene on one side, and the top of the placement platform 5 is made of granite.

[0039] Specifically, polytetrafluoroethylene (PTFE) has a low coefficient of friction, which reduces wear on the surface of the infrared germanium glass during clamping and prevents scratches. Furthermore, its chemical stability prevents chemical reactions with the glass, thus avoiding any impact on its performance. The top of the placement platform 5 is made of granite, which has high hardness and stability, providing a solid and stable support for the infrared germanium glass and ensuring that the placement platform 5 is not easily deformed. This guarantees the positional accuracy of the infrared germanium glass during processing and helps improve the overall processing quality.

[0040] When using the device, the user first places the infrared germanium glass on the placement platform 5 with a granite top to provide stable support. Then, the cylinder 6 is activated to push the sliding block 3 connected to it on the slide rail 2. The rear sliding block 3 drives the rotating rod 14 and the rotating component 15 to rotate. The rotating component 15 then drives the other two rotating rods 14 to move, thereby causing the other two sliding blocks 3 to slide on the slide rail 2. Finally, the clamping components 4 on the adjacent sides of the polytetrafluoroethylene material on the top of the three sliding blocks 3 move synchronously towards the middle to clamp and fix the infrared germanium glass.

[0041] When processing reaches the stage requiring cooling, cleaning, or chemical treatment with different liquids, motor 16 is turned on. Motor 16 drives worm gear 17 to rotate, worm gear 17 drives worm wheel 12 to rotate, and worm wheel 12 drives rotating column 19 to rotate within the inner diameter of connector 18. This causes the conveying groove 20 inside rotating column 19 to rotate towards different water tanks 13. These water tanks 13 are fixedly connected to connector 18 on the top right side of base plate 1, providing various liquids. Water pump 7 is turned on, and liquid is drawn from water tank 13 through delivery pipe 8, and sprayed out from nozzle 9 through corrugated pipe 10 and rotary joint 11, realizing different treatments for infrared germanium glass, including deionized water cooling, alkaline cleaning solution containing surfactants, and chemical treatment with hydrofluoric acid solution. All structures work together throughout the process to meet processing requirements.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
