[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model discloses a novel bearing grinding machine fixture, comprising: a mounting base 1 and an adjustment assembly. The upper surface of the mounting base 1 is provided with an abutment moving block 11. The abutment moving block 11 achieves initial positioning by contacting the upper surface of the mounting base 1, providing a base platform for subsequent component installation. The side wall of the abutment moving block 11 is provided with a second fitting mounting groove 13 and a limiting fitting groove 14. The second fitting mounting groove 13 is used to cooperate with an abutment clamping post 17, and the limiting fitting groove 14 is used to cooperate with a mounting limiting block 18. The two components work together to restrict the movement direction and position of the locking post 17. The outer surface of the second fitting mounting groove 13 is provided with a first fitting mounting groove 12, which provides installation space for the mating block 19, allowing it to accurately embed and connect with the moving block 11. The mating block 19 is located inside the first fitting mounting groove 12. By fitting and installing with the first fitting mounting groove 12, the mating block 19 connects the locking post 17 and the moving block 11, transmitting force. A through hole 15 is provided inside the mating block 19, providing a channel for the mounting positioning bolt 16 to pass through and connect with the moving block 11. The mounting positioning bolt 16 is located inside the through hole 15. By engaging with the adjusting nut 20, the mounting positioning bolt 16 fixes the mating block 19 onto the moving block 11, ensuring connection stability. The outer surface of the mounting positioning bolt 16 is threaded with the adjusting nut 20, and the adjusting nut 20 abuts against the lower surface of the moving block 11. The mother 20 adjusts its position on the mounting positioning bolt 16 by rotating, thereby adjusting the tightness of the abutment clamping column 17. The abutment clamping column 17 is fixedly connected to the side wall of the mating block 19. Under the action of the mating block 19, the abutment clamping column 17 can abut and clamp the bearing, thereby fixing the bearing. The upper and lower surfaces of the abutment clamping column 17 are fixedly connected to the mounting limit block 18. The mounting limit block 18 is embedded in the limit mating groove 14 to limit the rotation and displacement of the abutment clamping column 17 and ensure its accurate positioning.

[0025] The second fitting groove 13 and the limiting groove 14 are arranged in a cross pattern. This arrangement effectively restricts the contact locking post 17 in both directions, improving the stability of the locking. The interiors of the first fitting groove 12 and the second fitting groove 13 are connected. This connection facilitates the installation of the mating block 19 and the contact locking post 17, allowing them to be assembled smoothly. The mounting positioning bolt 16 extends to the upper surface of the contact moving block 11, facilitating installation and disassembly by operators and improving work efficiency. The dimensions of the mating block 19 and the first fitting groove 12 are matched to ensure that the mating block 19 can be tightly embedded in the first fitting groove 12, guaranteeing the accuracy and stability of the connection. The mounting limiting block 18 is positioned... Inside the limiting groove 14, the movement of the abutting locking post 17 is effectively restricted through the cooperation of the two, so that it can only be adjusted within a specified range. The two mounting positioning bolts 16 are symmetrically arranged on the front and rear sides of the abutting moving block 11. The symmetrical arrangement makes the force evenly distributed, which improves the clamping effect of the abutting locking post 17 on the bearing. The size of the abutting locking post 17 is adapted to the size of the second fitting mounting groove 13, ensuring that the abutting locking post 17 can slide freely in the second fitting mounting groove 13, while ensuring the clamping force and accuracy. The mounting limiting block 18 is located between the two mounting positioning bolts 16. This layout allows the mounting limiting block 18 to better play its limiting role, while avoiding interference with the mounting positioning bolts 16.

[0026] The upper surface of the mounting base 1 is provided with an adjustment component, which can adjust the position and height of the abutting moving block 11 to adapt to the processing requirements of bearings of different sizes and shapes. The adjustment component includes a sliding mounting groove 2, a sliding positioning groove 3, a limiting positioning bolt 4, a limiting slider 5, a reinforcing rib 6, a lifting adjustment plate 7, a height adjustment groove 8, a height positioning bolt 9, and a height sliding groove 10. The components cooperate with each other to achieve multi-dimensional adjustment of the abutting moving block 11. Sliding mounting grooves 2 are provided around the upper surface of the mounting base 1. The sliding mounting grooves 2 provide sliding tracks for the limiting slider 5, allowing it to move on the upper surface of the mounting base 1. Sliding positioning grooves 3 are provided on the front and rear sides of the upper surface of the sliding mounting grooves 2. The sliding positioning grooves 3 are connected to the sliding positioning bolt 5. The limiting positioning bolts 4 are used to position the limiting slider 5, ensuring that it will not shift during operation. The sliding mounting groove 2 is fixedly connected to the limiting slider 5 by the limiting positioning bolts 4. The limiting slider 5 slides within the sliding mounting groove 2 and is fixed in the required position by the limiting positioning bolts 4, providing support and positioning for the lifting adjustment plate 7. The lifting adjustment plate 7 is fixedly connected to the upper surface of the limiting slider 5. The lifting adjustment plate 7 moves with the movement of the limiting slider 5 and can be adjusted in height to meet the bearing processing requirements of different heights. The front and rear sides of the side wall of the lifting adjustment plate 7 are fixedly connected with reinforcing ribs 6. The reinforcing ribs 6 enhance the structural strength of the lifting adjustment plate 7, improve its load-bearing capacity, and ensure stability during operation. The lifting adjustment plate 7 has height adjustment grooves 8 on both the front and rear sides of one side. These grooves provide sliding channels for the height positioning bolts 9, allowing for height adjustment on the lifting adjustment plate 7. The height positioning bolts 9 are slidably connected to the inner surface of the height adjustment grooves 8. By sliding within the height adjustment grooves 8, the height of the abutting moving block 11 is adjusted, and it is fixed at the desired height via a threaded connection. A height sliding groove 10 is provided on the side of the lifting adjustment plate 7 away from the reinforcing rib 6. The height sliding groove 10 communicates with the height adjustment grooves 8, providing space for height adjustment of the abutting moving block 11, enabling smooth lifting and lowering movement. The limiting positioning bolt 4 is slidably connected to the inner surface of the sliding positioning groove 3. This connection method allows the limiting positioning bolt 4 to slide smoothly. The positioning bolt 4 can slide freely within the sliding positioning groove 3, ensuring the positioning accuracy of the limiting slider 5. The limiting positioning bolt 4 and the inner surface of the sliding mounting groove 2 abut against each other. This abutment enhances the friction between the limiting slider 5 and the sliding mounting groove 2, improving the stability of the limiting slider 5. The interior of the height adjustment groove 8 and the interior of the height sliding groove 10 are connected. This connection structure allows the height positioning bolt 9 to pass smoothly through the height adjustment groove 8 and the height sliding groove 10, realizing the height adjustment of the abutting moving block 11. Both height positioning bolts 9 are threadedly connected to the interior of the abutting moving block 11. Through the combined action of the two height positioning bolts 9, the stability and accuracy of the abutting moving block 11 during the height adjustment process are ensured.The number of limit sliders 5 and the number of sliding mounting slots 2 are set in a corresponding manner. This correspondence ensures that each limit slider 5 can slide within its corresponding sliding mounting slot 2, guaranteeing the coordination and stability of the adjustment components.

[0027] Working principle: First, fix the mounting base 1 on the grinding machine worktable, ensuring it is stable and without shaking. Using the cooperation of the sliding mounting groove 2 and the sliding positioning groove 3, initially place the limiting slider 5 at a suitable position on the upper surface of the mounting base 1. Use the limiting positioning bolt 4 for pre-fixation, allowing the limiting slider 5 to slide within the sliding mounting groove 2 but not yet locked. According to the dimensions of the bearing to be processed, push the limiting slider 5 along the sliding mounting groove 2 to the target position, ensuring the lifting adjustment plate 7 is directly above the bearing processing area. Tighten the limiting positioning bolt 4 to align it with the inner surface of the sliding mounting groove 2. The surfaces are in close contact, and simultaneously embedded in the sliding positioning groove 3, achieving lateral positioning of the limiting slider 5. Loosen the height positioning bolt 9, allowing the abutting moving block 11 to freely rise and fall within the limitation range of the height sliding groove 10 and the height adjustment groove 8. According to the height of the bearing, move the abutting moving block 11 up and down to a suitable position to ensure that the abutting clamping post 17 can contact the outer surface of the bearing. Tighten the height positioning bolt 9 to fix the abutting moving block 11 on the lifting adjustment plate 7. Embed the mating block 19 into the first fitting mounting groove 12, so that the abutting clamping post 17 is aligned with the second fitting mounting groove. 13. Slide the mounting limit block 18 into the limiting mating groove 14. The mounting positioning bolt 16 passes through the through hole 15 and extends to the upper surface of the abutting moving block 11. Screw the adjusting nut 20 into the lower end of the bolt so that it abuts against the lower surface of the abutting moving block 11. Place the bearing in the working area between the abutting clamping pins 17. By rotating the adjusting nut 20, the mounting positioning bolt 16 drives the mating block 19 to move towards the bearing until the abutting clamping pin 17 is tightly attached to the outer surface of the bearing. Due to the limiting effect of the mounting limit block 18 in the limiting mating groove 14, the abutting clamping pin 17... The clamping column 17 can only move in a straight line to ensure that the clamping force is evenly distributed. Check that all bolts are tightened, especially the limit positioning bolt 4 and the height positioning bolt 9, to ensure that the entire fixture system is stable. Before starting the grinder, confirm again that the bearing has been reliably fixed and that the contact moving block 11 shows no signs of loosening under the support of the reinforcing rib 6. After processing, first loosen the adjusting nut 20 to disengage the contact clamping column 17 from the bearing surface, then loosen the height positioning bolt 9 and the limit positioning bolt 4, adjust the contact moving block 11 and the limit slider 5 to the initial position, and take out the processed bearing.
