This invention provides an automated assembly and tightening device for shaft-end nuts that is easy to verify, belonging to the field of industrial manufacturing technology. This invention achieves full automation of the nut assembly process by integrating components such as a base, conveying mechanism, nut supply device, assembly robotic arm, tightening mechanism, and verification system. Its core lies in employing a two-stage tightening control strategy, dividing the tightening process into preliminary tightening and reinforcement tightening stages. In the preliminary tightening stage, a low-speed, high-precision mode and dynamic damping control ensure correct thread engagement. The intermediate verification stage measures axial displacement values ​​to promptly detect anomalies. In the reinforcement tightening stage, a stepped torque-increasing algorithm ensures uniform stress distribution. Finally, multi-parameter comprehensive verification evaluates the tightening quality and generates a traceability code, effectively solving the quality instability problem caused by a single-stage tightening method for shaft-end nuts.
