[0002] A prism is a polyhedral optical element made of transparent material, with the core feature of having two or more intersecting polished refracting surfaces. Its core function is to achieve optical effects such as beam deflection, light splitting, and light combining through refraction, dispersion or polarization of light. It is widely used in fields such as optical instruments, photographic equipment, and communication systems, and is a key component for achieving precise optical control.

[0003] During prism grinding, first perform appearance inspection on the prism blank, use tools such as diamond grinding wheels to quickly remove a large amount of machining allowance, use abrasives with finer granularity to finely grind the surface after rough grinding, continuously spray coolant during the grinding process to reduce the temperature of the processing area, use finer polishing materials to perform high-speed friction with the polishing pad, after polishing, remove residual abrasives and coolant on the surface by means of ultrasonic cleaning, and use optical instruments to detect surface indicators, and complete the processing after passing the inspection.

[0004] During the grinding process of the prism, grinding will heat the prism, causing the prism to deform and crack due to high temperature.

[0005] Therefore, a prism grinding device capable of improving the cooling effect is proposed to solve the above problems. Contents of the Utility Model

The S-shaped water delivery pipe increases the contact area with the heat conducting plate, making the cooling of the passing cooling water more uniform, and cooperates with the gooseneck pipe for precise spraying, so that the grinding area maintains a suitable temperature, reducing deformation and cracking of the prism caused by thermal expansion and cold contraction. After the cooling water flows back to the water tank through the leak holes, the grinding debris and failed grinding particles are removed through the filtering device, realizing recycling and reducing the cost of cooling water.

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 scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 3 As shown in the embodiment of this utility model, a prism grinding device that can improve cooling effect includes a water tank 1; a processing table 11 is fixedly connected to the top of the water tank 1; a grinding device body 12 is installed on the top of the processing table 11; a cooling chip 13 is embedded in the top of the water tank 1; a heat-conducting plate 14 is fixedly connected to the top of the processing table 11; the heat-conducting plate 14 is in contact with the cooling chip 13; a limiting groove 15 is opened on the top of the heat-conducting plate 14; a water supply pipe 16 is fixedly connected to the middle of the heat-conducting plate 14; the water supply pipe 16 is S-shaped; one end of the water supply pipe 16 is connected to the water tank 1; the other end of the water supply pipe 16 is fixedly connected to a gooseneck pipe 17; multiple leakage holes 18 are opened on the top of the processing table 11; a filter device 19 is installed inside the water tank 1; during operation, the prism processing plate is placed inside the limiting groove 15, the grinding device body 12 is used to grind the prism, and the gooseneck pipe 17 is bent so that its water outlet is aligned with the prism, and the water tank 1... An internal water pump is installed. When the pump is turned on, cooling water is delivered through the water pipe 16 to the gooseneck pipe 17 and then sprayed out. At the same time, the cooling plate 13 is turned on to release cold air, which cools the heat-conducting plate 14. The heat-conducting plate 14 conducts the cold air to the water pipe 16 and the prism processing plate, reducing the temperature of the prism and the cooling water. The used cooling water returns to the water tank 1 through the drain hole 18, is filtered by the filter device 19, and is reused. The cooling plate 13 cools the heat-conducting plate 14 and the S-shaped water pipe 16 simultaneously, achieving dual cooling of the cooling water and the prism. The S-shaped water pipe 16 increases the contact area with the heat-conducting plate 14, making the cooling water cool more evenly. Combined with the precise spraying of the gooseneck pipe 17, the grinding area is kept at a suitable temperature, reducing deformation and cracking caused by thermal expansion and contraction of the prism. After the cooling water flows back to the water tank 1 through the drain hole 18, it passes through the filter device 19 to remove grinding debris and failed grinding particles, achieving recycling and reducing the cost of cooling water.

[0027] like Figures 4 to 6 As shown, the filtration device 19 includes a slide rail 2; the slide rail 2 is fixedly connected to the inner walls on both sides of the water tank 1; a filter plate 21 is slidably connected to one side of the slide rail 2; a handle 22 is fixedly connected to one side of the filter plate 21; a bolt 23 is threadedly connected to one side of the water tank 1; the end of the bolt 23 passes through the slide rail 2 and is slidably connected to the filter plate 21; during operation, when replacing or cleaning the filter plate 21, the bolt 23 is rotated to separate it from the filter plate 21, and the handle 22 is pulled to pull the filter plate 21 out of the water tank 1 along the slide rail 2. Locking the filter plate 21 by rotating the bolt 23 can reduce the vibration generated by the grinding device body 12, which causes the filter plate 21 to shift along the slide rail 2, thereby increasing the stability of filtration. The sliding of the filter plate 21 along the slide rail 2 can reduce the friction between the filter plate 21 and the inner wall of the water tank 1 when replacing the filter plate 21, extending the service life of both and reducing maintenance costs.

[0028] like Figure 3 and Figure 6 As shown, multiple lifting slides 3 are fixedly connected to the bottom of the water tank 1; multiple levels 31 are fixedly connected to the side wall of the processing table 11; during operation, the position of the bubble in each level 31 is observed, and the lifting height of different lifting slides 3 is adjusted individually to keep the water tank 1 level. The level of the processing table 11 can be intuitively judged by the bubble in the level 31. The height can be adjusted individually with the lifting slides 3, making the operation simple and precise, increasing site adaptability. After the processing table 11 is leveled, tilting during prism grinding can be reduced, increasing the flatness and parallelism of the prism.

[0029] like Figures 1 to 6 As shown, multiple heat dissipation fins 4 are fixed to both sides of the water tank 1; the heat dissipation fins 4 are arranged in a wave shape; during operation, after the filtered cooling water returns to the water tank 1, the cooling water in the water tank 1 is heated. The temperature is conducted through the inside of the water tank 1 to the surface of the heat dissipation fins 4 on both sides, and comes into contact with the external airflow to cool down. The wave-shaped structure of the heat dissipation fins 4 can increase the heat dissipation area, pre-cool the cooling water, reduce the heat carried by the cooling water, and reduce the power consumption of the cooling chip 13.

[0030] like Figure 4 As shown, an anti-collision pad 5 is fixed to the inner wall of the water tank 1; the anti-collision pad 5 is arranged corresponding to one side of the filter plate 21; during operation, when the filter plate 21 is put back into the water tank 1, the anti-collision pad 5 buffers the collision between the edge of the filter plate 21 and the inner wall of the water tank 1. By absorbing the impact force when the filter plate 21 is put back, the anti-collision pad 5 can reduce the deformation and cracking of the edge of the filter plate 21 due to the collision, or the scratching and wear of the inner wall of the water tank 1, thereby increasing the stability of the device and reducing maintenance costs.

[0031] like Figure 1 As shown, a baffle 6 is fixedly connected to the top of the processing table 11; the baffle 6 is arranged corresponding to the edge of the processing table 11; the baffle 6 is higher than the heat-conducting plate 14; during operation, the baffle 6 forms a barrier on the top of the processing table 11 to intercept the cooling water thrown out by the grinding device body 12 or flowing out from the surface of the processing table 11. The barrier formed by the baffle 6 can intercept the cooling water thrown out by the grinding device body 12 or flowing along the edge of the processing table 11, so that it returns to the water tank 1 through the drain hole 18, reducing the waste of cooling water and reducing the number of water replenishment times.

[0032] Working principle: By placing the prism processing plate inside the limiting groove 15, the prism is ground using the grinding device body 12. The gooseneck tube 17 is then turned so that its water outlet is aligned with the prism. A water pump is installed inside the water tank 1. Turning on the water pump delivers cooling water through the water pipe 16 to the gooseneck tube 17, where it is sprayed out. Simultaneously, the cooling plate 13 is turned on, dissipating cold air to cool the heat-conducting plate 14. The heat-conducting plate 14 conducts the cold air to the water pipe 16 and the prism processing plate, lowering the temperature of the prism and cooling water. Used cooling water returns to the water tank 1 through the drain hole 18, is filtered by the filter device 19, and is reused. When replacing or cleaning the filter plate 21, the bolt 23 is turned to... Separate from the filter plate 21, pull the handle 22 to pull the filter plate 21 out of the water tank 1 along the slide rail 2, observe the position of the bubble in each level 31, and adjust the lifting height of different lifting slides 3 individually to keep the water tank 1 horizontal. After the filtered cooling water returns to the water tank 1, the cooling water in the water tank 1 is heated. The temperature is conducted through the inside of the water tank 1 to the surface of the heat dissipation fins 4 on both sides, and comes into contact with the outside airflow to cool down. When the filter plate 21 is put back into the water tank 1, the anti-collision pad 5 buffers the collision between the edge of the filter plate 21 and the inner wall of the water tank 1. The baffle 6 forms a barrier on the top of the processing table 11 to intercept the cooling water from being thrown out by the grinding device body 12 or flowing out from the surface of the processing table 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
