Description

Technical Field

[0001] The present application relates to the technical field of bearing production, and more specifically, to a fixing fixture for bearing processing with a rapid cooling function. Background Art

[0002] According to ISO classification standards, precision bearings are divided into: P0, P6, P5, P4, P2. The grades increase in sequence, with P0 being ordinary precision and the other grades being precision grades. Of course, different classification standards and different types of bearings have different classification methods, but the meaning is the same. The performance of precision bearings requires the rotating body to have high runout accuracy, high-speed rotation, and small friction and friction change.

[0003] Patent No. CN219005836U discloses a fixing fixture for precision bearing processing, including a base plate, an upper side of the base plate is fixedly connected to an L-shaped support rod, the other end of the L-shaped support rod is provided with a fixing piece, the outer side of the fixing piece is sleeved with a bearing body, the fixing piece includes a shell fixedly connected to the L-shaped support rod, both sides of the shell are rotatably connected to threaded sleeves, the other side of the shell is provided with a transmission assembly for driving the threaded sleeve to rotate, the end of the threaded sleeve away from the shell is threadedly connected to a threaded rod, the end of the threaded rod away from the threaded sleeve is fixedly connected to a top block, the side of the top block away from the threaded rod is abutted against the inner wall of the bearing body, a telescopic rod is provided between the top block and the shell, when the threaded sleeve rotates, the threaded rod can be driven to extend or contract, and the top blocks on both sides expand simultaneously with the threaded rod to adapt to bearing bodies with different inner diameters, fix the bearing body from the inner ring of the bearing body, and improve the efficiency of bearing body processing.

Excessive temperature will cause the material to expand and contract, resulting in deviations in the processed dimensions, making it difficult to achieve the precise dimensions required by the design. It may also cause defects such as burns and cracks on the bearing surface, affecting the surface finish and integrity. Utility Model Content

[0030] The cooling component includes a rotating tube 5 , both sides of which are connected to two nozzles 6 , and a motor 10 is arranged inside the connecting rod 3 , and the motor 10 is used to drive the nozzles 6 to quickly cool down the bearing 4 .

[0031] Reference Figure 1-Figure 5 A cavity 9 is opened inside one end of the connecting rod 3, and the motor 10 is located inside the cavity 9. The output end of the motor 10 is fixedly connected to the first gear 11. A first connecting tube 7 is provided on the top of the connecting rod 3. One end of the first connecting tube 7 is connected to the second connecting tube 8. One end of the second connecting tube 8 extends into the cavity 9. The second connecting tube 8 is connected to the rotating tube 5. The second connecting tube 8 is rotatably connected to one end of the rotating tube 5. A second gear 12 is fixedly connected to the outer wall of the rotating tube 5. The second gear 12 is meshed with the first gear 11. The rotating tube 5 is rotatably connected to the connecting rod 3.

[0032] The cooling component can be used to quickly cool the bearing 4 when processing the bearing 4. The specific operation method is that after fixing the bearing 4, first, the motor 10 is driven. The motor 10 will drive the rotating tube 5 to rotate through the first gear 11 and the second gear 12. Since a sealing gasket is provided at the position where the rotating tube 5 is connected to the second connecting tube 8, the sealing of the connection can be ensured. At the same time, the water pump is driven to extract the coolant in the water tank 17, and the coolant is transported to the inside of the rotating tube 5 through the first connecting tube 7 and the second connecting tube 8, and then sprayed out through multiple nozzles 6. The coolant will be directly sprayed onto the inner wall of the bearing 4, thereby achieving a rapid cooling effect when processing the bearing 4. Through the rotation of multiple nozzles 6, the bearing 4 can be quickly sprayed and cooled from different angles, thereby improving the cooling efficiency, shortening the processing waiting time, and making the cooling coverage of the bearing 4 more uniform, avoiding local overheating or overcooling, and ensuring that the overall performance of the bearing 4 is not affected.

[0034] The bearing 4 can be fixed by the clamping assembly, specifically, the two electric push rods 13 are driven through the two clamping plates 15 to fix the inner wall of the bearing 4, which makes it convenient to process the outer wall of the bearing 4 and avoids the phenomenon of incomplete processing due to a fixed blind spot, thereby ensuring the stability of the fixation. The clamping plate 15 can be flexibly rotated within a certain range through the universal ball 14 to adapt to bearings 4 of different shapes and angles, thereby improving the versatility of the clamping. The friction pad 16 is made of rubber material, which increases the friction between the bearing 4 and the clamping, making the clamping more stable and not easy to slip.
