Description

Technical Field

[0001] The utility model relates to the technical field of sleeve pressing tooling, in particular to an aviation wing sleeve pressing tooling. Background Art

[0002] The aircraft wing is one of the important parts of the aircraft and is installed on the fuselage. The main function of the wing is to generate lift, and together with the tail, it forms good stability and maneuverability. The wing is usually composed of components such as wing spars, longitudinal walls, stringers, wing ribs and skins. The basic force-bearing components of the wing include longitudinal (along the wingspan direction) skeletons, transverse (along the airflow direction perpendicular to the wing spars) skeletons and skins. The longitudinal skeletons include wing spars, longitudinal walls and stringers, and the transverse skeletons include ordinary wing ribs and reinforced wing ribs. The wing has the characteristics of large size and heavy weight. During the assembly process of the wing, since most of the parts are interference fit, it is necessary to use a press-fit tooling to realize the assembly operation of the aircraft wing.

[0003] The existing patent number CN205870429U discloses a sleeve pressing tool, which belongs to the field of engineering machinery. It mainly includes a support mechanism, and a positioning device and a power device are respectively provided on both sides of the bottom of the support mechanism, and the power device cooperates with the guide ring at the bottom of the support mechanism; the power device includes a cylinder and a step top connected in sequence, and the step top cooperates with the guide ring; the positioning device includes a cylinder and a conical top that cooperate with each other; the support mechanism includes two side plates that cooperate with each other, a rib plate is provided between the upper parts of the two side plates, and a mounting plate is provided between the bottoms of the two side plates. The utility model has a simple structure, and adopts an air-top oil cylinder to provide the power for sleeve pressing. The cylinder and the conical top play a positioning and guiding role. Mechanical pressure sleeve pressing is replaced by manual impact, which greatly improves work efficiency. The utility model is mainly used for assembling bearings.

[0004] The prior art has the following problems:

[0005] 1. The existing aviation wing pressing tooling has a poor limiting effect on wing parts, which also causes the wing parts to fall off easily during the pressing process, reducing the practicality of the pressing tooling and making it inconvenient to promote;

[0006] 2. The existing aviation wing pressing tooling does not have the function of preventing parts from deformation. This also leads to the pressing force acting on the wing parts during the pressing process, causing the pressing end of the wing parts to be easily deformed, resulting in unqualified assembly of the wing parts and difficulties in subsequent assembly of the wing parts, which reduces the efficiency of assembly and increases the cost of assembly. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides an aviation wing pressing tooling, which solves the current problem that the limiting effect on wing parts is not particularly ideal, which also causes the wing parts to fall off easily during the pressing process, and lacks the function of preventing parts from deformation. This also causes the pressing force acting on the wing parts during the pressing process, causing the pressing end of the wing parts to be easily deformed, thereby causing the wing parts to be unqualified in assembly and difficulty in subsequent assembly of the wing parts.

[0008] To achieve the above purpose, the utility model provides the following technical solutions: an aviation wing pressing tool, comprising a support frame, a handle is arranged on the top of the support frame, a hinge is arranged at the bottom end of one side of the support frame, a limit frame is arranged below one side of the hinge, an anti-slip pad is arranged at the bottom end of the limit frame, a hydraulic cylinder is arranged in the middle of the bottom of the support frame, and an anti-parts deformation component is arranged at the bottom end of the hydraulic cylinder;

[0009] The anti-part deformation component includes a buffer seat, an elastic ball is arranged inside the buffer seat, a limiting block is arranged at the bottom of the elastic ball, a damping rod is arranged at the bottom of the limiting block, a compression spring is arranged on the outer surface of the damping rod, a top seat is arranged at the bottom of the compression spring, and an elastic layer is arranged at the bottom of the top seat.

[0010] As a preferred technical solution of the utility model, the support frame and the limiting frame are rotatably connected via a hinge, and the size of the support frame, the size of the hinge and the size of the limiting frame are matched.

[0011] As a preferred technical solution of the utility model, the limiting frame is arranged in an L-shape as a whole, and there are two groups of the limiting frames, which are arranged corresponding to each other in the middle of the supporting frame.

[0012] As a preferred technical solution of the present utility model, the anti-skid pad is installed on the limiting frame by bonding, the anti-skid pad is arranged in an L-shape as a whole, and the anti-skid pad is specifically made of rubber.

[0013] As a preferred technical solution of the utility model, the top end of the damping rod is connected to a limit block, the bottom end of the damping rod passes through the buffer seat and the compression spring and is connected to the top seat, and the size of the limit block is adapted to the size of the buffer seat.

[0014] As a preferred technical solution of the utility model, the compression spring is installed on the top seat by welding, the size of the top seat is matched with the size of the buffer seat, and the top seat is slidably connected to the outer surface of the buffer seat.

[0015] As a preferred technical solution of the present utility model, the elastic layer is specifically made of soft silicone material, and the elastic layer is installed on the top seat by bonding.

[0016] Compared with the prior art, the utility model provides an aviation wing pressing tool, which has the following beneficial effects:

[0017] 1. The aviation wing pressing tool is provided with hinges, limit frames, anti-skid pads, hydraulic cylinders and top seats. During the pressing process, the limit frames are first arranged in an L-shape as a whole, so that the wing parts can be limited and fixed through the force exerted on the wing parts by the two groups of limit frames in cooperation with the top seat, thereby improving the stability and firmness of the wing parts. Then, the friction force at the contact between the wing parts and the limit frames can be increased through the anti-skid pads, thereby further improving the limiting effect on the wing parts. Finally, the position of the limit frames can be adjusted through the hinges, so as to perform the pressing operation on wing parts of different sizes. This design avoids the problem of wing parts falling off during the pressing process, improves the practicality of the pressing tool, and facilitates promotion.

[0018] 2. The aviation wing pressing tool is provided with a hydraulic cylinder, an elastic ball, a limit block, a compression spring, a top seat and an elastic layer. When the hydraulic cylinder drives the top seat to press the wing parts, it first contacts the wing parts through the elastic layer to weaken the force of the pressing, and prevents the wing parts from being worn due to excessive force. The compression spring is then squeezed by the top seat, thereby driving the limit block to squeeze the elastic ball. At the same time, the elastic force of the elastic ball and the compression spring reacts on the top seat to further buffer the force of the pressing force, thereby improving the anti-part deformation effect of the pressing tool. This design enables the pressing tool to have the function of preventing part deformation, avoids the problem of deformation of the pressing end of the wing part during the pressing process, improves the assembly efficiency, and reduces the assembly cost.
