AI Technical Summary

Technical Problem

In the prior art, during the assembly process, the elastic sleeve of the thrust rod spherical bearing is scratched and the load distribution is uneven due to initial alignment deviation or tilt, which affects the service life. Moreover, the existing method reduces assembly efficiency and is difficult to adapt to large-scale production.

Method used

The design incorporates a hydraulic press with upper and lower proximity switches, a one-way throttle valve, and a two-position two-way solenoid valve to achieve multi-stage speed control. This allows the elastic sleeve to self-adjust during the pressing process. Combined with the induction bracket design, the speed can be adjusted to switch positions, thereby improving assembly efficiency.

Benefits of technology

While ensuring assembly quality, the pressing time was shortened, assembly efficiency was improved, and the process adaptability and versatility of the device were enhanced, avoiding scratches and uneven covering force caused by initial alignment deviation.
