A numerical control positioner for aircraft wing panel

Abstract

The invention discloses a numerical control positioner of an airplane wing wall plate and belongs to the technical field of airplane assembly. The numerical control positioner of the airplane wing wall plate comprises a base, a vertical column mounted on the base and a telescopic column mounted on the vertical column. A mounting seat with a guide rail is arranged at the front end of the telescopic column. A ball head in-place mechanism is arranged on the mounting seat. A sliding block matched with the guide rail is arranged at the bottom of the ball head in-place mechanism. A locking mechanism fixing the sliding block in position is further mounted on the guide rail. The ball head in-place mechanism can be matched with a process ball head to form ball hinge connection, thus the process ball head can freely rotate in the ball head in-place mechanism, or a fixed object can be directly sucked by being replaced with a vacuum suction device. When the airplane wing wall plate deforms in the longitudinal direction due to changing of the temperature, the sliding block slides on the guide rail, temperature deformation of the airplane wing wall plate in the X direction is adapted, and accordingly the motion precision and positioning precision of equipment are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to a numerical control positioner for aircraft wing wall panels. Background technique [0002] The main task of aircraft assembly is to realize the positioning and connection between parts. In the digital assembly system, laser or photogrammetry technology is usually used to realize the measurement and pose calculation of large aircraft components, construct a generalized size chain of aircraft assembly with data as the node, and use the numerical control positioner as the actuator to realize its pose adjustment. The numerical control positioner is a modular unit that can realize numerical control movement in the three coordinate directions of X, Y and Z. Multiple numerical control positioners in the same component positioning system can realize synchronous and coordinated movement. [0003] A single CNC positioner generally has three degrees of freedom of motion, X, Y, a...

AI Technical Summary

Problems solved by technology

The attitude adjustment position and movement speed of large parts of the aircraft are small, but their size and mass are relatively large, and there are few support points, which may cause impact on the positioner

[0004] The traditional aircraft wing panel numerical control positioner lacks the ability to deal with the dimensional change of the wing panel due to temperature deformation in the lateral direction. When the temperature deformation is large, the movement accuracy and final positioning accuracy of the equipment will be affected.
