Description

An aircraft skin docking tool

technical field

The invention relates to the field of aircraft skins, in particular to a docking tool for aircraft skins.

Background technique

Aircraft skin refers to the dimension-shaped components that surround the aircraft skeleton structure and are fixed on the skeleton with adhesives or rivets to form the aerodynamic shape of the aircraft. The skin structure composed of aircraft skin and skeleton has large bearing capacity and rigidity, but its own weight is very light, which plays the role of bearing and transmitting aerodynamic loads. After the skin is subjected to aerodynamic action, the force is transmitted to the connected fuselage wing frame. The force is complex, and the skin is in direct contact with the outside world. Therefore, the skin material is not only required to have high strength and good plasticity, but also a smooth surface. Has high corrosion resistance.

When the bottom skin of the aircraft is on the fixed frame, the skin will sink due to its own weight, so that the edges of the skin are not on the same plane, and the staff needs to manually push it up for riveting. When the staff pushes and supports the bottom skin, it may be Due to the inconvenience, the riveting operation fails, so an auxiliary device for assisting the butt joint of the skins is required.

SUMMARY OF THE INVENTION

The invention provides an aircraft skin docking tool, which solves the need for multiple workers to perform auxiliary operations for the skin docking, increases the work difficulty of the riveting operation, and realizes that the splicing operation can be performed by a single person.

The technical problem solved by the present invention can be realized by the following technical solutions:

An aircraft skin docking tool includes a bracket, a sliding sleeve, a sliding column, a first vacuum suction cup, a second vacuum suction cup, a handle, a movable clip, a clip, a first spring and a second spring, and the bracket is arched structure, one end of the bracket is detachably connected to the first vacuum suction cup, the other end of the bracket is embedded with a sliding sleeve, the sliding column is slidably connected in the sliding sleeve, the sliding column is provided with slots on both sides, and the handle One end is hinged to the inner and lower walls of the bracket, a first spring is detachably connected between one side of the handle and the bracket, the other side of the handle is hinged to one end of the movable flap, and the other end of the movable flap is located in the slot on one side of the sliding column. Inside, the sliding sleeve is hinged with a clamping strip, a second spring is provided at the hinged joint between the clamping strip and the sliding sleeve, one end of the clamping strip is located in the clamping groove on the other side of the sliding column, and the lower end of the sliding column is detachably connected to the second spring. Vacuum suction cups.

The middle part of the bracket and the handle are covered with a rubber layer.

A spring sheet is arranged at one end of the movable clip and the handle.

Both ends of the bracket are plugged with push handles.

The sliding sleeve is a square sleeve, and the sliding column is a square cylinder.

The sliding column is located in the second vacuum suction cup and is detachably connected with a support rod, and the other end of the support rod is detachably connected with a third vacuum suction cup.

The beneficial effects of the present invention are: because the first vacuum suction cup and the second vacuum suction cup are used, the fixed skin and the to-be-fixed skin can be simultaneously adsorbed, and the to-be-fixed skin can be attached to the installation position through the movement of the spool.

Due to the use of the pusher, the vacuum suction cup can be more easily pushed during suction, so that the suction of the vacuum suction cup is more reliable.

Due to the use of the movable flap, when the handle is moved, the sliding column can be pushed up by the movable flap to make the skin fit the installation position.

Since the sliding sleeve is a square sleeve, it is prevented from rotating when the sliding column slides, preventing the card slot from being separated from the movable card flap and the card bar.
