Description

Technical Field

[0001] This utility model relates to the field of multi-layer grinding wheel technology, specifically to an ultra-precision multi-layer grinding wheel assembly with good cooling effect. Background Technology

[0002] Multi-layer grinding wheels are made of multiple layers of CBN material, offering a long service life, stable grinding quality, and high efficiency. Although the initial cost is high, the average cost is actually lower because they can grind more workpieces. They are also well-suited for high-precision grinding processes.

[0003] However, the grinding wheel generates heat through friction during the grinding process. When the temperature is high, it may cause thermal deformation of the grinding wheel and the workpiece, resulting in scrapping. This increases costs and wastes time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultra-precision multi-layer grinding wheel assembly with good cooling effect.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An ultra-precision multi-layer grinding wheel assembly with good cooling effect includes a base, a stepped platform on the top of the base, a cooling box with a top opening at the lower part of the base, and a liftable drive motor at the higher part of the base. The output end of the drive motor is driven by an output shaft on which the grinding wheel is snapped. When the drive motor is at its lowest height, a part of the bottom of the grinding wheel is located inside the cooling box.

[0007] Preferably, the width of the cooling box opening is equal to the thickness of the grinding wheel, and the length of the cooling box opening is less than the diameter of the grinding wheel.

[0008] Preferably, the cooling box and the grinding wheel are in surface contact.

[0009] Preferably, when the drive motor is at its lowest position, the height of the grinding wheel inside the cooling box is at least 1 cm.

[0010] Preferably, a drive motor is installed inside the base on the higher side, and a vertical threaded rod is driven at the output end of the drive motor. A threaded block is threaded on the threaded rod, the threaded block passes through the base and is slidably connected to the base, and a mounting plate connected to the drive motor is fixed at the end of the threaded block.

[0011] Preferably, a fixing ring is fixed on the output shaft, and multiple fixing rods are fixed on the end of the fixing ring away from the drive motor. The grinding wheel has a slot for inserting multiple fixing rods, and a detachable limiting ring that abuts against the side of the grinding wheel is provided on the output shaft.

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

[0013] 1. This utility model uses the rotation of a grinding wheel for grinding. After grinding, the surface of the grinding wheel is immediately cooled by the cooling liquid in the cooling box, which achieves rapid cooling of the grinding wheel surface and avoids thermal deformation of the grinding wheel and workpiece due to high temperature, thereby ensuring the stable operation of the grinding work.

[0014] 2. This utility model avoids affecting the grinding work by making the length of the cooling box opening shorter than the diameter of the grinding wheel. At the same time, the surface contact between the cooling box and the grinding wheel minimizes the amount of coolant residue on the grinding wheel surface, which is beneficial for long-term use. Furthermore, the fact that the height of the grinding wheel inside the cooling box is at least 1cm ensures that the coolant can completely cover the surface of the grinding wheel for effective cooling.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 As shown, this utility model provides an ultra-precision multi-layer grinding wheel assembly with good cooling effect, including a base 1, as described above. Figure 3 As shown, the base 1 is configured as an L-shaped structure with a stepped platform. A cooling tank 2 with a top opening is located at the lower part of the base 1. The cooling tank 2 is filled with a cooling liquid, such as cold water. A drive motor 4 is installed inside the higher side of the base 1. The output end of the drive motor 4 is equipped with a vertical threaded rod 11. A threaded block 12 is threaded onto the threaded rod 11. The threaded block 12 passes through the base 1 and is slidably connected to the base 1. A mounting plate 3 located on the top surface of the higher part of the base 1 is fixed to the end of the threaded block 12. A drive motor 10 is mounted on the mounting plate 3. Figure 2 As shown, the output end of the drive motor 10 is provided with an output shaft 6 located above the cooling box 2. A retaining ring 7 is fixed on the output shaft 6, and a grinding wheel 5 with one side abutting against the retaining ring 7 is sleeved on the output shaft 6. Multiple retaining rods 8 are fixed to the end of the retaining ring 7 away from the drive motor 4, such as... Figure 4 As shown, the grinding wheel 5 has a slot 13 inside for inserting several fixing rods 8, and the output shaft 6 is provided with a detachable limiting ring 9 that abuts against the side of the grinding wheel 5.

[0025] The grinding wheel 5 is clamped onto the output shaft 6 by the fixing ring 7 and the limiting ring 9. At the same time, the output shaft 6 rotates by the slot 13 and the fixing rod 8, which drives the grinding wheel 5 to rotate, thus completing the grinding work. The drive motor 10 drives the threaded rod 11 to rotate, which in turn drives the threaded block 12 to descend along the threaded rod 11. The descent of the threaded block 12 drives the drive motor 4 and the output shaft 6 to descend, which in turn drives the grinding wheel 5 to descend until a part of the bottom of the grinding wheel 5 is located in the cooling box 2. The surface of the grinding wheel 5 is cooled by the cooling liquid in the cooling box 2.

[0026] The width of the opening of the cooling box 2 is equal to the thickness of the grinding wheel 5, and the length of the opening of the cooling box 2 is less than the diameter of the grinding wheel 5. This avoids the length being too long and affecting the grinding work on the surface of the grinding wheel 5. The cooling box 2 and the grinding wheel 5 are in surface contact. This surface contact minimizes the amount of coolant remaining on the surface of the grinding wheel 5, which is beneficial for long-term use. When the drive motor 4 is at its lowest height, the height of the grinding wheel 5 inside the cooling box 2 is at least 1 cm, ensuring that the coolant can completely cover the surface of the grinding wheel 5 for effective cooling.

[0027] In use, the grinding wheel 5 is placed on the output shaft 6 and the fixing rod 8 is inserted into the slot 13. The limiting ring 9 is installed on the output shaft 6 and the limiting ring 9 and the fixing ring 7 respectively abut against the two sides of the grinding wheel 5. The drive motor 10 works to drive the output shaft 6 and the grinding wheel 5 to descend until the grinding wheel 5 is inserted into the cooling box 2. The drive motor 4 works to drive the output shaft 6 and the grinding wheel 5 to rotate for grinding. The surface of the grinding wheel 5 after grinding will enter the cooling box 2 and be cooled immediately by the cooling liquid in the cooling box 2.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
