[0069] The mounting device 15 includes a lower support ring 16 for providing support, a telescopic rod 13 for providing power output, and a pressing sheet 14 for easy pressing. The mounting device 15 also includes a support rod 27, which is fixedly connected to the outer surface of the telescopic rod 13. The number of telescopic rods 13 is multiple and distributed left and right. The lower support ring 16 is fixedly connected to the panel 1

[0070] Working principle: The bearings that need to be cleaned are cleaned first. The bearings and related components are first placed in the cavity formed by the panel 1 and the support frame 2. The ultrasonic cleaner fixedly connected to the bottom inner wall of the panel 1 is started to thoroughly clean the bearings. The ultrasonic cleaner generates tiny bubbles through high-frequency vibration to finely clean the surface of the bearing to ensure that there is no dirt or old lubricant residue. After the cleaning is completed, the bearing is raised by the drive device 17 and the heating device 23 is started. The multiple heating devices 23 include a fan 24, a warm air pipe 25, an air guide port 26 and an air outlet 22. The fan 24 provides airflow. After being heated by the warm air pipe 25, the hot air is evenly distributed around the bearing through the air guide port 26. Due to the large number of heating devices 23, the temperature uniformity during the heating process is ensured, and the risk of damage to the bearing due to uneven temperature is reduced. The bearings that do not need to be cleaned are directly heated and blown to blow away the dust. While heating the bearing, the heating device 23 also achieves the synchronous drying of the bearing after cleaning, which reduces The operation steps improve the overall efficiency. When blowing, the upper cover plate 4 is closed. After the bearing is preheated, lubricant is applied and the bearing installation device 15 is used for installation. The installation device 15 includes a lower support ring 16, a telescopic rod 13 and a pressing plate 14 to provide stable support and uniform installation power. The telescopic rod 13 is fixedly connected to the support rod 27. The lifting plate 20 is driven up and down by the driving motor 18 and the lead screw 19 to achieve precise installation of the bearing. The two left and right distributed detection components and moving components located on the upper side of the cavity start working. The detection component drives the frame 11 to rotate through the rotating shaft 10, and then adjusts the angle. The magnifying glass 12 inside the frame 11 is used to magnify and inspect the bearing and sealing components to ensure that there is no damage or wear. After the bearing is installed, use a rotating test device to check whether the bearing rotates smoothly without abnormal noise to confirm that the sealing effect is good. Finally, the vibration analyzer is used to detect the vibration of the bearing during operation to ensure that it is within the normal range without abnormal vibration or noise, thereby ensuring installation quality and operational stability.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
