Description

Technical Field

[0001] The invention belongs to the field of aircraft assembly and relates to an integral sliding box-section wing rib quick positioning device. Background Art

[0002] The box section wing ribs of the aircraft are characterized by large number, small rib spacing, and inconsistent structural dimensions. The positioning of the wing ribs is based on the positioning holes on the wing ribs, and the wing rib locators are used for positioning. The traditional box section wing rib positioning requires the corresponding wing rib locators to be set separately at multiple different rib positions, and the wing ribs at each station need to be set with corresponding shape pallets, and the wing rib locators at each station are installed and fixed on the corresponding pallets, and the pallets with wing rib locators are fixedly connected to the tooling frame through the corner seat. The wing rib locators and pallets are in a "one" to "one" relationship with the wing ribs, which will invisibly cause the types and quantities of wing rib locators and pallets to increase, which will lead to an increase in the manufacturing cost of the tooling and an increase in the installation cycle. The traditional wing rib locators will increase the labor intensity of workers, be time-consuming and labor-intensive, and inconvenient to operate, greatly reducing the positioning and assembly efficiency of the wing ribs, affecting production nodes, and delaying the aircraft delivery cycle. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that when positioning the box-section wing ribs, corresponding rib locators need to be separately set at multiple different rib positions to carry out the rib positioning method. An integral sliding box-section wing rib rapid positioning device is provided, in which the rib locators of multiple rib positions are installed and fixed on the same set of clamping plates, and the clamping plates with the rib locators installed can slide as a whole in the wingspan direction along the linear guide rail. Only one set of integral sliding positioning devices is needed to realize the rapid positioning of the ribs of multiple rib positions. The rib locators and the ribs are in a "one" to "many" relationship, which greatly reduces the types and quantities of rib locators and clamping plates, greatly reduces the manufacturing cost and installation cycle of tooling and the labor intensity of workers, realizes the rapid positioning and installation of the box-section wing ribs, and improves the assembly efficiency.
