[0002] The outer rotor of a backward centrifugal fan is the core component of the fan. In order to ensure the normal operation of the outer rotor of the fan, the bearing needs to be oiled and the retaining ring installation and inspection needs to be carried out on the assembled outer rotor. In addition, a dust cover needs to be installed to meet the installation and use requirements of the outer rotor of the fan. When installing the motor and the fan, butter needs to be added to the bearing. The butter affects the performance and service life of the fan rotor rotation. In addition, the retaining ring is used to prevent the fan rotor from falling off and vibrating, and the dust cover can prevent foreign matter from entering the bearing and shortening the service life of the fan. Existing fans need to rely on manual or semi-automatic equipment to add butter to the bearing, detect the presence of retaining rings, and install dust covers. It is impossible to complete multiple installation processes at one time and it is impossible to record installation data, and it is impossible to effectively process product information. Now an integrated installation device is needed to be suitable for the assembly and use of fan outer rotors of different models.

The press-fitting equipment and height detection equipment are used to realize automatic press-fitting and height detection of the motor worm on the output shaft of the actuator motor. The vacuum pump can form negative pressure at the first oiling component to recover the residual lubricating oil. The compressed air bag in the hydraulic system can realize positive pressure oiling of the second oiling component. The oiling and press-fitting of the integrated machine are carried out separately, and the operation efficiency is low. Summary of the invention
