Technical Field
[0001] The utility model relates to the technical field of bearing ring processing, in particular to a bearing ring cutting device. Background Art
[0002] Bearing rings are one of the core components of rolling bearings, divided into inner rings and outer rings. They jointly play the role of supporting the shaft and the rolling elements of the bearing. Bearing rings are usually made of high-carbon chromium steel (such as GCr15). After quenching and tempering treatment, the hardness can reach above HRC60. This high hardness makes the bearing rings have excellent wear resistance. During the processing of bearing rings, cutting devices are essential. They are used for precision machining of the inner and outer rings of bearings to achieve the required dimensions, shapes, and surface qualities.
[0003] When cutting bearing rings, first, the bearing rings need to be fixed, and then the cutting tool is started to perform the cutting operation on the bearing rings. However, the traditional fixing structure is relatively simple and can only fix bearing rings of the same size, and cannot fix bearing rings of different sizes. As a result, every time bearing rings of different sizes are replaced, the fixing device needs to be replaced or cumbersome adjustments need to be made, reducing the production efficiency.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] Refer to Figure 1 、 Figure 4 and Figure 5, an embodiment provided by the present utility model: a bearing ring cutting device, including a bracket 1, the upper part of the bracket 1 is fixedly connected with a processing table 3, the middle part of the bracket 1 is fixedly connected with a bottom plate 2, the upper part of the bottom plate 2 is provided with a cooling component 16, and the cooling component 16 is used to cool the cutting workpiece. The upper left side of the processing table 3 is fixedly connected with a first mounting frame 4. Both sides of the outside of the first mounting frame 4 are fixedly connected with mounting rods 5. A mounting disk 6 is fixedly connected to the outside of the plurality of mounting rods 5. The outside left side of the mounting disk 6 is fixedly connected with an electric push rod 7. The output end of the electric push rod 7 is fixedly connected with a moving block 8. One end of a connecting plate 10 is rotatably connected to the outside of the four sides of the moving block 8. Through holes 12 are opened in the four sides of the inside of the mounting disk 6. Fixed rods 13 are fixedly connected to the inside of the plurality of through holes 12. Sliders 11 are slidably connected to the outside of the plurality of fixed rods 13. The other ends of the plurality of connecting plates 10 are rotatably connected to the outside of the plurality of sliders 11. Connecting rods 14 are fixedly connected to the outside of the plurality of sliders 11. An arc-shaped clamping plate 23 is fixedly connected to the outside of the plurality of connecting rods 14. The upper right side of the processing table 3 is fixedly connected with a second mounting frame 19. An adjusting component 20 is arranged inside the second mounting frame 19, and the adjusting component 20 is used to adjust the position of the cutting workpiece. A protective pad 15 is arranged inside the plurality of arc-shaped clamping plates 2The outside of the four sides of the first mounting frame 4 is fixedly connected with one end of a guide rod 9. The other ends of the plurality of guide rods 9 are fixedly connected to the outside of the mounting disk 6. The moving block 8 is slidably connected to the outside of the plurality of guide rods 9. A collection box 22 is arranged on the upper part of the processing table 3.
[0026] When fixing bearing rings of different sizes, first, place the bearing ring to be fixed in the middle of the four arc-shaped clamping plates 23. At this time, the protective pad 15 keeps a certain distance from the outer surface of the bearing ring. Then, start the electric push rod 7, which will drive the moving block 8 fixed to the output end to move horizontally outside the four guide rods 9. During this process, the moving block 8 drives the four connecting plates 10 rotatably connected to the outside of its four sides to move synchronously. As the connecting plate 10 moves, the four sliders 11 rotatably connected to the other end of it will also move relatively outside the four fixed rods 13. This relative movement enables the four sliders 11 to drive the four connecting rods 14 fixed to the outside to move. The movement of the connecting rod 14 further drives the four arc-shaped clamping plates 23 to move towards the bearing ring. As the arc-shaped clamping plate 23 moves, the four protective pads 15 arranged inside it gradually approach the outer surface of the bearing ring. Finally, the protective pad 15 is in close contact with the outer surface of the bearing ring, thus completing the fixing of the bearing ring, realizing the convenient fixing of bearing rings of different sizes, reducing the adjustment time during each workpiece replacement, and improving the processing efficiency.
[0027] Refer to Figure 1 and Figure 2, the cooling assembly 16 includes a water pump 1601 which is fixedly connected to the upper part of the bottom plate 2. The input end of the water pump 1601 is fixedly connected to a water storage tank 1602 which is also fixedly connected to the upper part of the bottom plate 2. The output end of the water pump 1601 is fixedly connected to one end of a delivery pipe 1603, and the other end of the delivery pipe 1603 penetrates through the inside of the processing table 3 and is fixedly connected to a spray head 1604. A water injection port 18 is fixedly connected to the rear side outside the water storage tank 1602. Support rods 17 are fixedly connected to both sides outside the spray head 1604, and the bottoms of the two support rods 17 are fixedly connected to the upper part of the processing table 3.
[0028] When the cutting piece 2003 starts to work, the water pump 1601 is immediately started to extract cooling water from the inside of the water storage tank 1602. The extracted cooling water is conveyed through the delivery pipe 1603. Finally, the cooling water is sprayed out through the spray head 1604 to form a fine water mist. When the water mist is sprayed onto the cutting piece 2003, it can effectively reduce the temperature of the cutting area, slow down the wear speed of the cutting tool, and realize the facilitation of cooling the cutting piece 2003 during the cutting process of the bearing ring, reducing the working temperature of the cutting tool, slowing down the wear speed of the cutting tool, and thus prolonging the service life of the cutting tool.
[0029] Refer to Figure 2 and Figure 3 , the adjustment assembly 20 includes a cylinder 2001 which is fixedly connected to the inside of the second mounting bracket 19. The output end of the cylinder 2001 is fixedly connected to a moving plate 2002. A cutting piece 2003 is installed inside the moving plate 2002. Slide rods 21 are fixedly connected to both sides outside the second mounting bracket 19, and the moving plate 2002 is slidably connected to the outside of the two slide rods 21.
[0030] When it is necessary to adjust the position of the cutting piece 2003, by starting the cylinder 2001, the cylinder 2001 drives the moving plate 2002 fixed to its output end to move horizontally outside the two slide rods 21. When the moving plate 2002 moves, it drives the cutting piece 2003 installed inside to move, realizing the facilitation of adjusting the position of the cutting piece 2003, reducing the processing error, ensuring that each workpiece can meet the expected quality standard, thereby reducing the scrap rate and rework rate, and improving the production qualification rate.
[0031] Working principle: When fixing bearing rings of different sizes, first, place the bearing ring in the middle of the four arc-shaped clamping plates 23. Then, start the electric push rod 7. The electric push rod 7 drives the moving block 8 fixed to its output end to move horizontally outside the four guide rods 9. When the moving block 8 moves, it drives the four connecting plates 10 rotatably connected to its outer periphery to move together. When the four connecting plates 10 move, they drive the four sliders 11 rotatably connected to the other end to move relatively outside the four fixed rods 13. When the four sliders 11 move relatively, they drive the four connecting rods 14 fixed to their outer sides to move. The movement of the four connecting rods 14 drives the four arc-shaped clamping plates 23 to move. The movement of the four arc-shaped clamping plates 23 drives the four protective pads 15 arranged inside to move, so that the four protective pads 15 come into contact with the outside of the bearing ring, and the fixing of the bearing ring can be completed. It realizes the convenience of fixing bearing rings of different sizes, reduces the adjustment time during each workpiece replacement, improves the processing efficiency. Then, when the cutting part 2003 cuts the bearing ring, by starting the water pump 1601, the water pump 1601 pumps out the cooling water from the inside of the water storage tank 1602, then conveys it through the delivery pipe 1603, and finally sprays it out through the atomizing nozzle 1604 to cool the cutting part 2003. It realizes that during the cutting process of the bearing ring, it is convenient to cool the cutting part 2003, can reduce the working temperature of the cutting tool, slow down the wear speed of the cutting tool, and thus extend the service life of the cutting tool.
