A Mechanical Attitude Adjustment System for Wing Root Rib Positioning Tooling

Abstract

The invention discloses a mechanical posture adjusting system for a wing root rib positioning tool and belongs to the technical field of aircraft digital assembly. The mechanical posture adjusting system comprises a base assembly, a stand column assembly, a sliding plate assembly and a detecting assembly. The base assembly comprises a base, a spanwise guiding rail sliding block mechanism and an actuator. The stand column assembly is connected with the base in a sliding mode through the spanwise guiding rail sliding block mechanism and is driven by the actuator. The stand column assembly comprises a stand column and an oblique guiding rail sliding block mechanism. The sliding plate assembly comprises an oblique plane siding plate and a wing root rib fixing unit. The oblique plane siding plate is connected with the stand column in a sliding mode through the oblique guiding rail sliding block mechanism. The lower end of the oblique plane siding plate is supported on the stand column. The detecting assembly is used for detecting the relative replacement between the stand column assembly and the base as well as between the oblique plane siding plate and the stand column. By adoption of the mechanical posture adjusting system, multi-degree-of-freedom adjusting for positions and postures of a wing root rib clamped onto the system can be achieved, and the spatial interference problem brought by hoisting in-place can be avoided in the installation process.

Description

technical field [0001] The invention relates to an attitude adjustment system of an aircraft assembly tool, in particular to an attitude adjustment device of a wing root rib positioning tool. Background technique [0002] In the field of aircraft manufacturing, the attitude adjustment of fuselage components is the basis for docking assembly. Due to the large size, weak stiffness and complex shape of aircraft components, the attitude adjustment accuracy is high, and the attitude adjustment tooling is not allowed to cause damage to the surface or internal structure of the workpiece. [0003] Usually, the workpiece and the positioning tool are hoisted into place by driving for assembly. On the one hand, the large-size positioning tool is likely to interfere with the surrounding tooling during the hoisting process. The pose adjustment of the tooling has problems such as low assembly accuracy and large assembly stress. Contents of the invention [0004] The purpose of the pre...
