Description

Technical Field

[0001] This utility model relates to the field of warpage deformation detection technology, and more specifically, to a sealing ring warpage detection device. Background Technology

[0002] Currently, in the manufacturing process of nitrile rubber bearing seals with a skeleton, the skeleton is a stamped part, and the steel plate is relatively thin, making it prone to deformation. The skeleton is also susceptible to deformation in subsequent processing. Furthermore, the rubber surface itself has engravings and unevenness, making warpage detection essential. This is particularly important when used in bearings, where extremely high precision is required.

[0003] Meanwhile, there is no suitable equipment on the market for testing the warpage of nitrile rubber bearing seals with a skeleton. Similar bearing instruments include bearing height measuring gauges, which are only suitable for testing relatively hard solid parts with good rigidity, made entirely of metal. Because a measuring force is applied during the testing process, it will cause elastic deformation of the rubber when testing soft nitrile rubber seals with a metal skeleton, resulting in measurement errors, and is therefore unsuitable.

[0004] Therefore, how to accurately detect the warping deformation of soft, easily deformable sealing rings has become an urgent problem to be solved. Utility Model Content

[0044] Combination Figure 1-4As shown, the sealing ring warpage detection device provided in this embodiment includes:

[0045] The first workbench includes a first base plate 12 and a first fixing component, the first fixing component being disposed on the lower surface of the first base plate 12;

[0046] The support assembly is used to place the object to be tested 7. The support assembly includes a rotating shaft 4 and a turntable 5. One end of the rotating shaft 4 passes through the first base plate 12 along the Z-axis and is located below the first base plate 12. The other end of the rotating shaft 4 is connected to the turntable 5. The upper surface of the turntable 5 is also provided with a limiting member 6. Several limiting members 6 are provided, and one end of the limiting member 6 is rotatably connected to the upper surface of the turntable 5.

[0047] A detection component is located on one side of the support component, and the detection component is used to detect the object to be detected 7.

By passing a fastening bolt through the strip-shaped hole of the limiting member 6, one end of the limiting member 6 can be connected to the turntable 5, so that the other end of the limiting member 6 can rotate along the fastening bolt. When the object to be tested 7 is placed on the turntable 5, the object to be tested 7 is fixed by rotating the limiting member 6. The limiting member 6 can be displaced and is suitable for sealing rings of different specifications. At the same time, it prevents the object to be tested 7 from slipping during rotation and ensures the safety of operation.

The four partitions 22 surround to form an inner cavity.

[0059] Specifically, in this embodiment, the drive component 3 is located within the inner cavity. Placing the turntable 5 and the drive component 3 in different spaces improves the safety of the device operation.

[0060] Specifically, in this embodiment, the support column 16 is preferably a cubic column. The side of the support column 16 parallel to the Z-axis has a groove. The four partitions 22 are set on the opposite outer surfaces of the four support columns 16 by corresponding fastening bolts and fastening blocks. The fastening blocks are locked inside the grooves. One end of the fastening bolt passes through the partition 22 and is connected to the corresponding fastening block.

[0061] Understandably, in this embodiment, the second worktable and support assembly improve the stability and accuracy of the detection. The support assembly is positioned between the two worktables along the Z-axis and consists of four support columns 16 and four partitions 22. The support columns 16 connect the upper and lower worktables, and the partitions 22 are disposed on the outer surface of the support columns 16 to form an inner cavity. This not only enhances the stability of the device but also provides a separate internal space for the detection device, ensuring the smooth operation of the detection process.

[0063] An adjustable fixing component is provided on the upper surface of the second base plate 14;

[0066] It is understood that the adjustable fixing component in this embodiment allows the laser sensor 8 to flexibly adjust its position as needed, ensuring that it maintains the best detection state in different detection processes. At the same time, the laser sensor 8 improves the adaptability and flexibility of the detection component, enabling it to meet diverse detection needs.

At the same time, the two-color lamp 9 is set on the outer surface of the partition 22 near the turntable 5, which facilitates the observation of the detection results.

[0082] Understandably, in this embodiment, a stable connection between the laser sensor 8 and the turntable 5 is achieved through an adjustable fixing assembly. The arrangement of the first fixing member 17 and the first fixing rod 18, as well as the configuration of the second fixing member 19 and the second fixing rod 20, together ensure that the laser sensor 8 can be securely installed near the turntable 5 while maintaining necessary adjustment space. The adjustability of the extension length of the first fixing rod 18 allows the assembly to adapt to different installation height requirements, while the adjustability of the length between the second fixing rod 20 and the laser sensor 8 further enhances the installation flexibility, allowing for fine-tuning according to the specific measurement requirements of the object to be tested 7, thus improving the convenience and accuracy of installing the laser sensor 8.

[0083] In one specific embodiment of this application, the second fixing component includes four second fixing posts 15, which are disposed on the lower surface of the second base plate 14, and each of the two ends of the second fixing post 15 is in contact with a support post 16.

[0084] Specifically, in this embodiment, the second fixing post 15 is preferably a cubic post. A groove is provided on the side of the second fixing post 15 perpendicular to the Z-axis, which not only helps reduce weight but also provides installation space for the fastening bolts and fastening blocks, thereby achieving a secure connection with the second base plate 14. The second base plate 14 is connected to the second fixing assembly via corresponding fastening bolts and fastening blocks. The fastening blocks are engaged within the grooves, and one end of the fastening bolt passes through the second base plate 14 and connects to the corresponding fastening block.

The first base plate 12 is connected to the first fixing assembly through corresponding fastening bolts and fastening blocks. The fastening blocks are engaged inside the grooves, and one end of the fastening bolt passes through the first base plate 12 and is connected to the corresponding fastening block.

[0088] The specific working process of the sealing ring warpage detection device in this embodiment is as follows:

[0089] Before measurement, the operator needs to adjust the tooling, press the enable switch 1 to unlock the drive component 3, and allow the turntable 5 to rotate freely. Then, align the object to be tested 7 (a sealing ring) with the turntable 5. Adjust the laser sensor 8 so that the laser spot is perpendicular to the upper surface of the sealing ring. Manually rotate the turntable 5 one full turn to check if the laser spot of the laser sensor 8 is consistently illuminating the upper surface of the sealing ring. If the laser spot is not completely illuminating the upper surface of the sealing ring, readjust the positions of the sealing ring and the laser sensor 8 to ensure that the laser spot is completely illuminating the upper surface of the sealing ring during one full rotation. After determining the positions of the sealing ring and the laser sensor 8, adjust the limiting component 6 to make it close to the sealing ring, then tighten the fastening bolts of the limiting component 6, and finally fix the position of the laser sensor 8. After adjusting the positions of the sealing ring and the laser sensor 8, rotate the turntable 5 to a position convenient for loading and unloading, and then turn off the enable function of the drive component 3 using the enable switch. The laser spot of the laser sensor 8 is projected onto the turntable 5. The zeroing button on the decoder 11 is pressed to confirm that the height of the turntable 5 is zero, thus completing the model change adjustment.

[0090] When the measurement begins, press the measurement button 2. The measurement signal controls the drive component 3 to start rotating and sends a start signal to the laser sensor 8. After the laser sensor 8 collects the height data of the sealing ring around one revolution, the decoder 11 calculates the dispersion based on the sealing ring thickness data. Then, it determines whether the product is qualified based on the dispersion value and sends a corresponding signal to the programmable logic controller (PLC) 10. The PLC 10 outputs the corresponding signal to the two-color light 9. The operator can determine whether the product is qualified based on the two-color light 9 or the measurement result displayed on the decoder 11.
