AI Technical Summary
During the fabrication of the array composite tube sandwich, the poor cylindricity of the composite tube unit leads to poor relative position accuracy between units during the array forming process. The lack of precise positioning features results in errors in the relative position and orientation of the front and back sides of the sandwich, making it impossible to accurately match with the skin, generating excessive internal structural stress, and failing to meet service requirements.
A device and method for measuring and compensating the pose error of a large array of composite tubes with flip-over clamping is proposed. The reference feature point carrier is installed through an internal expansion device, the coordinates of the feature point are measured by a machine tool probe, and the three-dimensional rigid body transformation matrix method is combined to calculate and compensate for the three-axis rotation angle deviation, so as to achieve accurate measurement and compensation of the pose of the front and back of the workpiece.
It improves the accuracy of the relative positions of the front and back sides of the array composite tube interlayer, reduces the rework rate, and increases the product qualification rate, resulting in significant economic and quality benefits.
