Description

Technical Field

[0001] This utility model relates to the field of aircraft engine blade installation technology, specifically to an auxiliary frame for aircraft engine blade installation. Background Technology

[0002] As a key component of aero engines, aircraft engine blades play a decisive role in the engine's thrust, efficiency, reliability, and service life. Based on engine type and operating location, aircraft engine blades can be mainly divided into two categories: worm gear engine blades and ramjet engine blades. In terms of installation, these blades are typically mounted and fixed to the rotor using a tenon-mortise joint structure.

[0003] In the current process of installing aircraft engine blades, it is usually necessary to manually align the blades of different specifications with the tenons on the wheel and insert them, and then tap them in with a rubber hammer. However, since the blades of different specifications have different masses, installing blades with larger masses will consume a lot of time and energy for the workers, which is not conducive to long-term operation and affects the installation efficiency. In order to install aircraft engine blades of different specifications more conveniently and improve the installation efficiency, this application proposes an aircraft engine blade installation auxiliary frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary frame for mounting aircraft engine blades, including an electric base 1. Two horizontal guide rail components 2 are symmetrically arranged on both sides of the top of the electric base 1. A horizontal mounting frame 3 is arranged on the top of the two horizontal guide rail components 2. Two vertical guide rail components 4 are symmetrically arranged at both ends of one side of the top of the horizontal mounting frame 3. A vertical mounting frame 5 is arranged on one side of the two vertical guide rail components 4. Multiple spring rubber wheel components 6 are evenly spaced at both ends of the vertical mounting frame 5 on the side away from the vertical guide rail components 4. A cylinder push plate component 7 is arranged on the other side of the vertical mounting frame 5.

[0018] The electric base 1 includes a base plate 101, and multiple drive steering wheels 102 are fixedly connected to both sides of the lower surface of the base plate 101. By setting the electric base 1, it is easy to drive the engine blades to the designated position, which facilitates installation and improves installation efficiency.

[0019] Among them, the two horizontal guide rail components 2 include two horizontal electric guide rails 201, and two horizontal electric sliders 202 are slidably connected on the two horizontal electric guide rails 201 respectively. The bottom of the horizontal electric guide rails 201 is fixedly connected to both sides of the upper surface of the base plate 101. By setting the two horizontal guide rail components 2, the horizontal mounting bracket 3 can be driven to move horizontally, thereby driving the engine blades closer to the wheel disc, which is convenient for installation.

[0020] The bottom ends of the horizontal mounting bracket 3 are fixedly connected to the tops of the two horizontal electric sliders 202, respectively.

[0021] Among them, the two vertical guide rail components 4 include two vertical electric guide rails 401, and two vertical electric sliders 402 are slidably connected to the two vertical electric guide rails 401 respectively. One side of the vertical electric guide rail 401 is fixedly connected to both sides of the horizontal mounting frame 3. By setting the vertical guide rail components 4, the vertical mounting frame 5 can be moved up and down, thereby driving the engine blades on the multiple spring rubber wheel components 6 to rise, saving the physical strength of the staff and facilitating the installation.

[0022] The vertical mounting bracket 5 includes a vertical mounting plate 501. Two slider mounting plates 502 are horizontally and symmetrically fixedly connected to both ends of one side of the vertical mounting plate 501. Two vertical electric sliders 402 are fixedly connected to both ends of the other side of the vertical mounting plate 501. Two reinforcing plates 503 are symmetrically fixedly connected to the lower surfaces of the two slider mounting plates 502 on opposite sides. Multiple waist-shaped grooves 504 are evenly spaced on the slider mounting plate 502. One end of the two reinforcing plates 503 is fixedly connected to the vertical mounting plate 501. By setting the reinforcing plates 503, the structural strength of the slider mounting plate 502 can be enhanced, which facilitates better support of multiple spring rubber wheel components 6, lifting engine blades of different weights for auxiliary installation.

[0023] The spring rubber wheel component 6 includes a wheel fixing seat 601, a rubber wheel 602 rotatably connected to one side of the wheel fixing seat 601, a slider 603 fixedly connected to the top of the wheel fixing seat 601, and two guide rods 604 symmetrically fixedly connected to both ends of the other side of the wheel fixing seat 601. The slider 603 is horizontally slidably connected to the slider mounting plate 502 through the waist-shaped groove 504. Two springs 605 are fixedly connected to one end of the two guide rods 604 near the wheel fixing seat 601, and the other end of the guide rods 604 is horizontally slidably connected to the reinforcing plate 503. The other end of the two springs 605 is fixedly connected to the reinforcing plate 503. By setting the rubber wheel 602, when the rubber wheel 602 is engaged with the tenon of the engine blade, it can avoid scratching and protect the engine blade.

[0024] The cylinder pusher plate component 7 includes a cylinder 701. The output end of the cylinder 701 passes through the vertical mounting plate 501 and is fixedly connected to a pusher plate 702. The cylinder 701 is fixedly connected to the vertical mounting plate 501. A rubber plate 703 is fixedly connected to the other side of the pusher plate 702. The pusher plate 702 is located above the rubber wheel 602. By setting the rubber plate 703, the engine blades can be prevented from being crushed when pushing them into the wheel.

[0025] Working principle: The tenon of the engine blade is aligned with the insertion between multiple spring rubber wheel components 6. The rubber wheel 602 contacts the engine blade, which in turn drives the two guide rods 604 on the wheel fixing seat 601 to slide along the reinforcing plate 503. The slider 603 slides along the groove, which further drives the spring 605 to contract, so that the rubber wheel 602 is pressed against the engine blade and locks the top engine blade tenon. Multiple drive steering wheels 102 work to transport the engine blade to the designated position. Two vertical electric guide rails 401 drive two vertical electric sliders 402 to rise, which in turn drives the engine blade on the vertical mounting bracket 5 to rise to the installation height, so that the tenon of the engine blade is horizontally aligned with the tenon of the wheel disk. Then, two horizontal electric guide rails 201 drive two horizontal electric sliders 202 to move, which in turn drives the horizontal mounting bracket 3 to move, so that the engine blade is close to the wheel disk. Finally, the cylinder 701 pushes the push plate 702, which pushes the engine blade through the rubber plate 703 and pushes it into the wheel disk, completing the installation.
