The motorcycle industry also has great development potential in emerging markets. At the same time, the rise and promotion of motorcycle culture, such as motorcycle clubs, racing events, etc., also contribute to promoting motorcycle consumption and industry development. However, the industry also faces some challenges, such as fierce market competition, high requirements for investment in technological innovation, etc. In the process of motorcycle assembly and production, the manual assembly method of rim bearings is relatively widespread. When the position of the rim bearing is offset, the subsequent assembly process cannot be carried out and must be eliminated.

[0003] However, in the traditional manual assembly process of rim bearings, due to the reverse installation order of the front and rear rim bearings, the position of the rim bearing will be offset, making it difficult to install the bearing in place. When manually detecting the displacement, the whole process has low efficiency and low accuracy. Therefore, an anti-misassembly structure for pressing a rim bearing is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an anti-misassembly structure for pressing a rim bearing, aiming to improve the problems that in the traditional manual assembly process of rim bearings, due to the reverse installation order of the front and rear rim bearings, the position of the rim bearing will be offset, making it difficult to install the bearing in place, and when manually detecting the displacement, the whole process has low efficiency and low accuracy.

[0005] To achieve the above object, the utility model adopts the following technical scheme: an anti-misassembly structure for pressing a rim bearing, including a bottom plate, the top of the bottom plate is fixedly connected with a mounting seat, the top of the bottom plate is fixedly connected with two gland covers, the top of the gland cover is fixedly connected with a guide post, a compression spring is sleeved outside the guide post, a guide sleeve is fixedly connected to the outside of the guide post, a floating plate is slidably connected to the outside of the guide post, the top of the floating plate is fixedly connected with two end covers, and a position error correction component is installed outside the floating plate, and the error correction component is used for correcting the position of the bearing.

[0006] As a further description of the above technical solution:

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: an anti-misalignment structure for press-fitting a wheel hub bearing, including a bottom plate 1, a mounting seat 2 fixedly connected to the top of the bottom plate 1, two pressure covers 10 fixedly connected to the top of the bottom plate 1, a guide post 8 fixedly connected to the top of the pressure cover 10, a compression spring 9 sleeved on the outside of the guide post 8, a guide sleeve 7 fixedly connected to the outside of the guide post 8, a floating plate 11 slidably connected to the outside of the guide post 8, two end covers 12 fixedly connected to the top of the floating plate 11, a position error correction assembly installed outside the floating plate 11, and the error correction assembly is used for position error correction of the bearing; one end of the compression spring 9 is fixedly connected to the top of the pressure cover 10, and the other end of the compression spring 9 is fixedly connected to the bottom of the floating plate 11; the inner wall of the mounting seat 2 is slidably connected to the outside of the lower pressing head 3.

[0027] Further, during use, place the rim bearing at the bottom of the pressure signal. After the lower pressing head 3 is placed, place the sensor 4 at the bottom of the sensor mounting bracket 6 so that the sensor 4 is located on top of the rim bearing. Then, drive the sensor 4 to swing through the swing arm 14. At this time, control the floating plate 11 to move downward along the guide post 8. Further, the floating plate 11 drives the lower pressing head 3 to move downward simultaneously until the lower pressing head 3 contacts the outside of the bearing. The compression spring 9 is used to compensate for the machining error of the workpiece, ensuring that the bearing can be installed in the correct position on the rim. Compared with manual installation, the installation error can be greatly reduced. The compression spring 9 is limited by the gland 10 and the floating plate 11, making the compression spring 9 more stable. The lower pressing head 3 is further limited by the mounting seat 2, enabling the lower pressing head 3 to better fix the bearing.

[0028] Refer to Figure 1 and Figure 2 , the position correction component includes a lower pressing head 3. The lower pressing head 3 is fixedly connected to the bottom of the floating plate 11. An outer positioning block 13 is fixedly connected to the top of the floating plate 11. An inner positioning block 5 is fixedly connected to the inside of the floating plate 11. A sensor mounting bracket 6 is fixedly connected to the bottom of the floating plate 11. An inner side of the outer positioning block 13 is fixedly connected to a swing arm fixing seat 15. A swing arm 14 is rotatably connected to the bottom of the swing arm fixing seat 15. A sensor 4 is fixedly connected to the outside of the swing arm 14. The outside of the swing arm 14 is respectively in contact with the inner sides of the inner positioning block 5 and the outer positioning block 13. The outside of the sensor 4 is slidably connected to the outside of the sensor mounting bracket 6. The sensor 4 and the lower pressing head 3 are combined in the same structure.

[0029] Further, in addition, drive the sensor 4 to change its position through the swing arm 14, causing the internal signal of the detection sensor 4 to change. That is, by observing the numerical change of the sensor 4, detect whether the position of the rim is correctly placed. When the sensor 4 is contacted and the pressure signal of the sensor 4 is normal, it indicates that the workpiece is placed qualified. When the rim bearing is misinstalled or missed, the pressure signal of the sensor 4 is abnormal, indicating that the workpiece is placed unqualified. At this time, continue to control the lower pressing head 3 until the pressure signal of the sensor 4 is normal, that is, the workpiece is placed qualified. At the same time, the inner positioning block 5 has the functions of preventing missed installation and misinstallation, with high detection accuracy and sensitivity, stable and reliable, facilitating automation and intelligence, reducing the influence of human factors on the assembly process, and further increasing the installation accuracy. The swing arm 14 is limited by the inner positioning block 5 and the outer positioning block 13 to control the movement range of the swing arm 14, making the detection effect more ideal. The sensor 4 is supported by the sensor mounting bracket 6 to further protect the sensor 4 and effectively extend its service life. The cooperation between the sensor 4 and the lower pressing head 3 can reduce the number of processes, thereby shortening the processing time and improving the processing efficiency.

[0030] Working principle: During use, place the rim bearing at the bottom of the pressure signal. After the lower pressing head 3 is placed, put the sensor 4 on the top of the rim bearing. Then, swing the swing arm 14, which drives the sensor 4 to swing simultaneously. At this time, control the floating plate 11 to move downward along the guide post 8. Further, the floating plate 11 drives the lower pressing head 3 to move downward simultaneously until the lower pressing head 3 contacts the outside of the bearing. The compression spring 9 is used to compensate for the machining error of the workpiece, ensuring that the bearing can be installed in the correct position of the rim and further improving the installation efficiency.

[0031] In addition, through the change in the position of the swing arm 14, the internal signal of the detection sensor 4 is changed. Thus, by observing the change in the value of the sensor 4, it can be detected whether the rim is placed correctly. When the sensor 4 is contacted and the pressure signal of the sensor 4 is normal, it indicates that the workpiece is placed qualified. When the rim bearing is misinstalled or not installed, the pressure signal of the sensor 4 is abnormal, indicating that the workpiece is placed unqualified. Continue to control the lower pressing head 3 until the pressure signal of the sensor 4 is normal. At the same time, the lower positioning block 5 has the functions of preventing misinstallation and missing installation, with high detection accuracy and sensitivity, stable and reliable, facilitating the realization of automation and intelligence, and reducing the influence of human factors on the assembly process.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
