A Test to Measure the Rate of Adsorption Deformation of Flexible Assembly Tooling

Abstract:

Traditional tooling for aircraft skin will produce a large clamping deformation of the inadequacies in the assembly process, designed a vacuum suction cup flexible assembly tooling, that tooling using vacuum suction force to clamp the workpiece in the assembly process, greatly reduces the amount of deformation of the workpiece. In order to accurately grasp the new tooling excellent performance in terms of adsorption deformation, through the establishment of a laser measuring device test platform, we conducted a large number of studies of vacuum adsorption deformation experiment on different thickness of the workpiece,has been obtained the workpiece adsorption deformation rate range under the flexible tooling system, as well workpiece thickness, sucker adsorption, the number of anchor effect on the adsorption deformation rate of the workpiece, and verify the reasonableness of the flexible assembly tooling.
