Description

Technical Field

[0001] The present invention relates to the field of aircraft skins, and more particularly to an aircraft skin docking tooling. Background Art

[0002] An aircraft skin refers to a tapered member that surrounds the aircraft frame structure and is fixed to the frame with adhesives or rivets to form the aerodynamic shape of the aircraft. The skin structure formed by the aircraft skin and the frame has relatively large load-bearing capacity and stiffness, but its own weight is very light, and it plays a role in bearing and transmitting aerodynamic loads. After the skin bears the aerodynamic force, the force is transmitted to the connected fuselage and wing frames. The force is complex. In addition, since the skin is in direct contact with the outside world, not only is it required that the skin material has high strength and good plasticity, but also the surface is smooth and has high corrosion resistance.

[0003] When the bottom skin of the aircraft is fixed to the frame, due to the self-weight of the skin, it will sink, causing the edges of the skin not to be in the same plane. Workers need to manually push it up before riveting. When the bottom skin is pushed by the workers, the riveting operation may fail due to inconvenience. Therefore, an auxiliary device for assisting skin docking is needed. Summary of the Invention

[0004] The present invention provides an aircraft skin docking tooling, which solves the problem that multiple workers are required to assist in the skin docking operation, increasing the working difficulty of the riveting operation, and realizes that a single person can perform the splicing operation.

[0005] The technical problems solved by the present invention can be achieved by the following technical solutions:

[0006] An aircraft skin docking tooling includes a bracket, a sliding sleeve, a sliding column, a first vacuum suction cup, a second vacuum suction cup, a handle, a movable clamping flap, a clamping strip, a first spring and a second spring. The bracket is in an arch structure. One end of the bracket is detachably connected to the first vacuum suction cup at the lower part. The other end of the bracket is internally embedded with the sliding sleeve. The sliding column is slidably connected in the sliding sleeve. Card slots are opened on both sides of the sliding column. One end of the handle is hinged to the inner lower wall surface of the bracket. One side of the handle is detachably connected to the bracket by the first spring. The other side of the handle is hinged to one end of the movable clamping flap. The other end of the movable clamping flap is located in the card slot on one side of the sliding column. The clamping strip is hinged to the sliding sleeve. A second spring is arranged at the hinge of the clamping strip and the sliding sleeve. One end of the clamping strip is located in the card slot on the other side of the sliding column. The lower end of the sliding column is detachably connected to the second vacuum suction cup;

[0007] Pull the handle close to the bracket, while compressing the first spring. The handle rotates around the hinge with the bracket, lifting the movable clamping flap to move, and the movable clamping flap pushes the card slot of the sliding column, causing the sliding column to move.

[0008] The middle part of the bracket and the outside of the handle are wrapped with rubber layers.

[0009] A spring plate is provided at one end of the handle and the movable valve flap.

[0010] Push hands are inserted at both ends of the bracket.

[0011] The sliding sleeve is a square sleeve, and the sliding column is a square column.

[0012] One side of the sliding column and above the second vacuum suction cup is detachably connected with a support rod, and the other end of the support rod is detachably connected with a third vacuum suction cup.

[0013] The beneficial effects of the present invention are as follows: Since the first vacuum suction cup and the second vacuum suction cup are used, the fixed skin and the skin to be fixed can be adsorbed and fixed at the same time. When the sliding column moves, the skin to be fixed is fitted to the installation position.

[0014] Since the push hands are used, when the vacuum suction cup performs adsorption, it can be more easily pushed, making the adsorption of the vacuum suction cup more reliable.

[0015] Since the movable valve flap is used, when the handle moves, the sliding column can be pushed to move upward through the movable valve flap, so that the skin fits the installation position.

[0016] Since the sliding sleeve is a square sleeve, rotation is prevented when the sliding column slides, preventing the card slot from disengaging from the movable valve flap and the card strip. BRIEF DESCRIPTION OF THE DRAWINGS
