An automatic assembly and tightening device for shaft end nuts that is easy to verify

ActiveCN120816300BRealize fine controlRealize verificationAxial displacementStress distribution
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.

Sodium hydroxide in the absorbent reacts with iodine in the exhaust gas to form iodide, thus converting iodine from the gas phase to the liquid phase, achieving iodine absorption and capture. After absorption and capture, the exhaust gas passes through a demisting section to capture entrained droplets before being discharged from the top of the tower system. The exhaust gas detection system measures the concentration of iodine in the exhaust gas. This method enables efficient gas-liquid contact and mass transfer, and achieves constant-temperature circulation and composition control of the alkaline solution.
