Description

Technical Field

[0001] This utility model application relates to the field of spraying device technology, specifically a spraying device for precision polishing liquid of optical glass. Background Technology

[0002] Optical glass is a type of glass that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. It is a fundamental and important component of the optoelectronic technology industry and can be used to manufacture lenses, prisms, mirrors, and windows in optical instruments. To improve transparency and refractive index, reduce surface defects and irregular reflections, reduce light scattering, improve light utilization, and enhance wear resistance and corrosion resistance, optical glass needs to be polished.

[0003] In order to effectively remove minor scratches and imperfections on the glass surface and improve optical performance during the polishing process, polishing fluid needs to be sprayed. The polishing fluid spraying device needs to be adjusted in real time according to the polishing position. However, most existing spraying devices are inconvenient to adjust according to the polishing position, which greatly reduces the practicality of the spraying device. Utility Model Content

[0004] To address the problem that existing optical glass precision polishing slurry spraying devices are inconvenient to adjust according to the polishing position during use, this utility model provides an optical glass precision polishing slurry spraying device to solve the above-mentioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An optical glass precision polishing liquid spraying device includes a liquid storage tank and a threaded telescopic tube. The bottom of the liquid storage tank is connected to the threaded telescopic tube through a one-way valve. A nozzle is connected to the end of the threaded telescopic tube away from the liquid storage tank. A liquid inlet is connected to the top surface of the liquid storage tank. A sealing cap is threaded onto the liquid inlet. A rotatable fixing frame is connected to the nozzle. A fixing plate is slidably fitted inside the fixing frame. A fixing screw is rotatably connected to the top surface of the fixing plate through a bearing. The fixing screw is threaded into the inside of the fixing frame.

[0007] Furthermore, a servo motor is fixedly installed at the center of the top of the liquid storage tank, and a stirring rod is rotatably connected inside the liquid storage tank. The stirring rod rotates through the top of the liquid storage tank and is fixed to the output end of the servo motor.

[0008] Furthermore, the fixing frame is configured as a horizontally placed U-shape, and the top surfaces of the fixing plates on both sides of the fixing screw are fixed with limit rods, which are slidably inserted into the fixing frame.

[0009] Furthermore, a connecting screw is fixed to the bottom surface of the fixed frame, an adjusting ball is fixed to the connecting screw, a connecting base is rotatably sleeved on the adjusting ball, the bottom surface of the connecting base is fixed to the nozzle, and a fixing cover is threaded onto the connecting screw.

[0010] Furthermore, the connecting base is configured as an inverted T-shape, the bottom of the connecting base is configured as an arc shape to cooperate with the nozzle, and the connecting base has a rotating groove inside to cooperate with the adjusting ball.

[0011] Furthermore, the height of the fixing sleeve is greater than the distance between the top surface of the adjusting ball and the bottom surface of the connecting base, and the distance between the bottom surface of the connecting base and the bottom surface of the fixing frame is greater than the height of the fixing sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the adjustable nozzle can be fixed near the polishing head and move with the polishing head during use, thus facilitating spraying. This solves the problem that existing optical glass precision polishing liquid spraying devices are inconvenient to adjust according to the polishing position during use, and greatly improves the practicality of the spraying device.

[0014] 2. In this utility model, the polishing liquid is stirred in time by the stirring rod to avoid the polishing liquid in the storage tank from settling and affecting its effect. In addition, the rotatable design of the nozzle allows the nozzle angle to be adjusted after the nozzle is fixed, which further improves the practicality of the spraying device.

Detailed Implementation

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figures 1 to 3 An optical glass precision polishing liquid spraying device includes a liquid storage tank 1 and a threaded telescopic tube 2. A servo motor 15 is fixedly installed at the center of the top of the liquid storage tank 1. A stirring rod 16 is rotatably connected inside the liquid storage tank 1. The stirring rod 16 rotatably passes through the top of the liquid storage tank 1 and is fixed to the output end of the servo motor 15. The bottom of the liquid storage tank 1 is connected to the threaded telescopic tube 2 through a one-way valve 3. A nozzle 4 is connected through the end of the threaded telescopic tube 2 away from the liquid storage tank 1. A liquid inlet 5 is connected through the top surface of the liquid storage tank 1. A sealing cap 6 is threaded on the liquid inlet 5. A rotatable fixing frame 7 is connected to the nozzle 4. A fixing clamp 8 is slidably sleeved inside the fixing frame 7. A fixing screw 9 is rotatably connected to the top surface of the fixing clamp 8 through a bearing. The fixing screw 9 is threaded inside the fixing frame 7. The fixing frame 7 is set as a horizontally placed U-shape. Limiting rods 10 are fixed on the top surface of the fixing clamp 8 on both sides of the fixing screw 9. The limiting rods 10 are slidably inserted inside the fixing frame 7.

[0022] Specifically, when the spraying device is to be used, first unscrew the sealing cap 6 to open the liquid inlet 5, add the polishing liquid to the storage tank 1 through the liquid inlet 5, then screw the sealing cap 6 onto the liquid inlet 5 and fix it, put the fixing frame 7 on the accompanying part of the polishing head, and screw the fixing screw 9 to drive the fixing clamp 8 and the limiting rod 10 to move, so that the fixing clamp 8 and the fixing frame 7 cooperate to clamp and fix the nozzle 4 on the accompanying part. When spraying, open the one-way valve 3 and the servo motor 15. After the one-way valve 3 is opened, the polishing liquid is sprayed out through the nozzle 4 through the one-way valve 3. The servo motor 15 runs intermittently to drive the stirring rod 16 to rotate and stir the polishing liquid inside the storage tank 1.

[0023] As an optimization solution, such as Figure 1 and Figure 2As shown, a connecting screw 11 is fixed to the bottom surface of the fixed frame 7, and an adjusting ball 12 is fixed to the connecting screw 11. A connecting base 13 is rotatably sleeved on the adjusting ball 12. The connecting base 13 is set as an inverted T-shape, and the bottom of the connecting base 13 is set as an arc shape to cooperate with the nozzle 4. A rotating groove to cooperate with the adjusting ball 12 is opened inside the connecting base 13. The bottom surface of the connecting base 13 is fixed to the nozzle 4. A fixing sleeve 14 is threaded on the connecting screw 11. The height of the fixing sleeve 14 is greater than the distance between the top surface of the adjusting ball 12 and the lower top surface of the connecting base 13. The distance between the lower top surface of the connecting base 13 and the bottom surface of the fixed frame 7 is greater than the height of the fixing sleeve 14.

[0024] Specifically, after the nozzle 4 is fixed on the accompanying part, the fixing cover 14 is turned so that the fixing cover 14 and the connecting base 13 are pressed together. The nozzle 4 is rotated, which drives the connecting base 13 to rotate on the adjusting ball 12, thereby adjusting the angle of the nozzle 4. After the adjustment is completed, the fixing cover 14 is turned in the opposite direction so that the fixing cover 14 is pressed and fixed on the connecting base 13, thus fixing the nozzle 4.
