AI Technical Summary

⚠Technical Problem

The existing rotor eccentric shaft and needle roller bearing assembly process has problems such as assembly position deviation and non-compliance with coaxiality standards, which leads to unstable equipment operation. In addition, the existing automatic correction device is costly or relies on manual adjustment, resulting in low efficiency.

⚗Method used

The system employs a cylinder-driven eccentric gripper and sensor assembly to monitor the assembly status in real time and automatically adjust the position and angle of the eccentric shaft and needle roller bearing. A polyurethane buffer layer is used to protect the workpiece, achieving automated and precise correction.

🎯Benefits of technology

It improves assembly accuracy and efficiency, reduces human error, enhances equipment operational stability and reliability, and simplifies equipment maintenance.
