2results about How to "Simplify the alignment process" patented technology

This application relates to a duct mechanism and an air supply device. The duct mechanism includes: a duct assembly comprising a duct shell and a bushing, the outer wall of which has a first positioning portion radially; and a support base having a shaft hole channel, the two opposite ends of which along their axial direction are an inner end near the duct shell and an outer end away from the duct shell, respectively, and a stop portion surrounding the outer end is formed on the support base; wherein the bushing passes through the shaft hole channel from the outer end and is detachably connected to the duct shell, and the bushing is also rotatably connected to the shaft hole channel, and the stop portion is used to stop and limit the first positioning portion along the axial direction of the bushing. The duct mechanism of this application simplifies the positioning and alignment process of the duct assembly and support base during assembly, quickly and accurately completing the rotatable connection assembly of the entire duct assembly and support base, improving the connection efficiency and accuracy of the duct assembly and support base, reducing the production difficulty of the duct mechanism, and improving the production quality and efficiency of the air supply device.

This invention discloses an adaptive balancing lifting device for aircraft door assembly and disassembly, belonging to the field of lifting device technology. It includes a lifting frame, lifting components, and a clamping assembly. The clamping assembly is equipped with a flexible component containing magnetofluid and a corresponding excitation component, which can adapt to the curved surface of the door and actively harden to provide reliable clamping. The lifting device also integrates a multi-degree-of-freedom angle adjustment component and a vision-feedback-based active balancing system. Before handling, the clamping angle can be adjusted to align the door using the longitudinal and lateral adjustment components. During handling, a vision camera detects the door's attitude in real time, and the control system drives independent lifting components on both sides for dynamic leveling. Micro-vibrations are absorbed by adjusting the magnetofluid state, achieving adaptive flexible gripping, precise attitude adjustment, and stable anti-sway handling of irregular doors, significantly improving the safety, accuracy, and efficiency of assembly and disassembly operations.
