Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing and testing technology, and in particular to a method for detecting the vertical difference of the outer ring of a bearing. Background Technology
[0002] As a key component in mechanical transmission systems, the manufacturing precision of bearings directly affects the stability and reliability of equipment operation. The perpendicularity difference of the bearing outer ring is an important indicator for measuring bearing quality, namely the perpendicularity error of the outer ring end face to the raceway. If this parameter exceeds the tolerance, it will cause abnormal loads, vibrations and noises during bearing operation, and shorten the service life.
[0003] However, in existing technologies, it is difficult to quickly and accurately adjust the detection reference plane to the ideal vertical state in traditional equipment, which affects the accuracy of measurement data. The connection between the measuring block and the positioning seat is often fixed by bolts, but when inspecting bearings of different specifications, it is necessary to frequently disassemble and install the measuring block, which is cumbersome and time-consuming, reducing the detection efficiency and failing to meet the detection needs of modern bearing production with large batches and many specifications. Therefore, a bearing outer ring vertical difference detection method is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 6This utility model provides an embodiment of a bearing outer ring vertical difference detection method, comprising an operating table 1 and a base plate 3. The base plate 3 is fixedly connected to the side of the operating table 1 via an angle adjustment assembly, which converts rotational motion into angular change, suitable for high-precision and high-efficiency testing requirements in bearing mass production. A positioning seat 4 is fixedly connected to the top of the operating table 1, and a measuring block 5 is installed in the middle of the positioning seat 4 via a snap-fit assembly; the snap-fit assembly is suitable for the rapid switching testing requirements of multiple specifications in bearing mass production.
[0034] The angle adjustment assembly includes a fixed base 13, to which a drive motor 14 is fixedly connected. A threaded rod 15 is fixedly connected to the output end of the drive motor 14. The drive motor 14 drives the threaded rod 15 to rotate, converting the rotational motion into linear motion of the slider 20. The slider 20 is threadedly connected to the outside of the threaded rod 15. The slider 20 is connected to a fixed block 18 via a fixed shaft 19. Simultaneously, the fixed shaft 19 slides within a groove 23, constraining the movement trajectory of the slider 20. Fixed shafts 19 are fixedly connected to both ends of the slider 20, and fixed blocks 18 are fixedly connected to the outside of the fixed shafts 19. Grooves 23 are provided on both sides of the fixed base 13. The grooves 23 restrict the movement trajectory of the fixed shafts 19, ensuring the accuracy of the linear motion of the slider 20 and preventing inaccurate angle adjustment due to movement deviation. The fixed shaft 19 is slidably connected in the middle of the groove 23.
[0035] The angle adjustment assembly also includes a connecting rod 21, which connects two fixed shafts 19. When the slider 20 moves, the operating table 1 rotates around the second fixed shaft 26, thereby achieving angle adjustment. The connecting rod 21 is rotatably connected to the outside of one of the fixed shafts 19, and the other end of the connecting rod 21 is rotatably connected to the outside of the other fixed shaft 19. A fixing block 22 is fixedly connected to the bottom of the operating table 1, and the other fixed shaft 19 is fixedly connected to the middle of the fixing block 22. A mounting block 16 is fixedly connected to the outside of the fixed base 13, and a screw 17 is fixedly connected to the middle of the mounting block 16. The screw 17 securely connects the fixed base 13 to the base plate 3, providing stable support for the entire angle adjustment mechanism and preventing shaking during operation.
[0036] Reference Figure 3 , Figure 4 and Figure 5The latching assembly includes a mounting block 6, which is fixedly connected to the outside of the positioning seat 4. A housing 11 is fixedly connected to the middle of the mounting block 6. The mounting block 6 and housing 11 provide mounting support for the pull rod 7 and the spring 10. The pull rod 7 is slidably connected to the middle of the housing 11. When the pull rod 7 is inserted into the bayonet 12 of the measuring block 5, it fixes the measuring block 5 onto the positioning seat 4, ensuring that there is no relative displacement between the two during measurement and avoiding detection errors due to loosening. A spring 10 is sleeved on the outside of the pull rod 7. When the pull rod 7 is inserted into the bayonet 12, the spring 10 is compressed and generates thrust, keeping the pull rod 7 firmly engaged in the bayonet 12, enhancing the reliability of the connection. A retaining ring 9 is fixedly connected to the outside of the pull rod 7, preventing the spring 10 from being over-compressed or the pull rod 7 from falling out of the housing 11, while ensuring that the elastic force of the spring 10 acts on the pull rod 7. The snap-fit assembly also includes a pull ring 8. Pulling the pull ring 8 moves the pull rod 7 outward, disengaging it from the latch 12. At this time, the spring 10 is compressed, allowing the measuring block 5 to be quickly removed. After releasing the pull ring 8, the spring 10 returns to its original position, pushing the pull rod 7 back into the latch 12, completing the installation. The pull ring 8 is fixedly connected to the front end of the pull rod 7, and the latch 12 is provided in the middle of the measuring block 5, where the pull rod 7 engages with the latch 12.
[0037] Reference Figure 1 and Figure 2 Two fixing blocks 24 are fixedly connected to the top of the base plate 3. These two fixing blocks 24 are symmetrically fixed to the top of the base plate 3, providing support for the fixing shaft 26. The fixing shaft 26 is fixedly connected to the middle of each of the two fixing blocks 24, preventing radial displacement during rotation. A fixing block 25 is fixedly connected to the outside of the fixing shaft 26. The fixing block 25 is fitted onto the outside of the fixing shaft 26 and connects to the fixing block 22, forming the rotation fulcrum of the operating table 1. The fixing block 22 is rotatably connected to the outside of the fixing shaft 26. When the angle adjustment component pushes the operating table 1 to tilt, the fixing block 22 rotates around the fixing shaft 26, realizing the angle change of the operating table 1. A slot 2 is provided in the middle of the operating table 1, and a positioning seat 4 engages with the slot 2. The bottom surface of the slot 2 is parallel to the top surface of the operating table 1. After the positioning seat 4 is installed, it ensures the uniformity of the measurement reference of the bearing outer ring end face.
[0038] Working principle: When it is necessary to adjust the tilt angle of the operating table 1 through the angle adjustment component so that the deviation between the bearing outer ring end face on the positioning seat 4 and the theoretical vertical plane is controlled within a very small range, the drive motor 14 is first started to drive the threaded rod 15 to rotate. While the threaded rod 15 rotates, it drives the slider 20 to move together, converting the rotational motion of the threaded rod 15 into the linear displacement of the slider 20. The slider 20 pushes the fixed block 22 through the fixed shaft 19 and the connecting rod 21. The fixed shaft 19 drives the connecting rod 21 to slide on the slide groove 23, and makes the operating table 1 rotate around the fixed shaft 26.
[0039] The outer ring of the bearing is then placed on the positioning seat 4. The matching measuring block 5 is quickly installed using the snap-fit assembly. First, the pull rod 7 extends forward under the elastic force of the spring 10, so that the pull rod 7 is snapped into the slot 12 of the measuring block 5, ensuring that the measuring block 5 is tightly connected to the positioning seat 4. When it is necessary to disassemble or replace the measuring block 5 of different specifications for testing, pull the pull ring 8 and pull the pull rod 7 outward, so that the pull rod 7 is disengaged from the slot 12. At this time, the measuring block 5 can be removed freely, completing the disassembly. After releasing the pull ring 8, the spring 10 returns to its original position and pushes the pull rod 7 back, waiting for the next snap-fit.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
