Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of assembly workbench after aircraft generator repair, and specifically to an assembly workbench for aircraft generator repair. Background Technology
[0002] Aircraft generators are similar to ordinary generators in that they convert mechanical energy into electrical energy through electromagnetic induction. Typically, the mechanical energy generated by the aircraft engine drives the generator rotor to rotate. The rotation of the rotor induces voltage on the stator. This voltage is converted into direct current by a rectifier and then converted into the required voltage by a transformer. Like traditional generators, aircraft generators require regular inspection and maintenance. However, traditional maintenance benches have a fixed scope and area, which limits the operable area for maintenance.
[0003] Existing aircraft generator repair benches have a fixed usable area and limited scope of use. For example, CN221314045U discloses an auxiliary bench for disassembling aircraft generators, which includes a base with symmetrical hydraulic cylinders fixedly connected to the upper end. Each hydraulic cylinder has an upward-opening hydraulic chamber on its upper surface, and a hydraulic rod slides within the chamber. Connecting blocks and adjusting motors are fixedly connected to the outer surfaces of the upper ends of the two sets of hydraulic rods. An air-blowing assembly for cleaning the surface of the aircraft generator is also provided on the base. A clamping seat is rotatably fitted to the upper end of the flipping block via a bearing. A clamping module for clamping the generator is provided on the clamping seat. This invention uses the clamping module to fix the aircraft generator, then activates the adjusting motor to flip it at an angle. The power motor rotates, causing the clamping seat to rotate and adjust the disassembly angle. The combination of lifting and flipping angle adjustments makes the disassembly operation more convenient and efficient. However, the auxiliary bench in this design has a fixed usable area and limited operability, preventing flexible assembly and extension of the work surface.
[0004] Therefore, it is necessary to invent an assembly workbench for aircraft generator repair to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide an assembly workbench for aircraft generator maintenance, so as to solve the problem that the usable area and usage range of the maintenance workbench of aircraft generators are fixed in the technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An assembly workbench for aircraft generator maintenance includes a first track, a main maintenance platform, a main operating platform, a main work surface, a second track, an auxiliary maintenance platform, an auxiliary work surface, and an auxiliary plate. The main maintenance platform is slidably connected to the first track, and a main operating platform is mounted on the main maintenance platform. A main work surface is mounted on the main operating platform. Second tracks are located on both sides of the first track. An auxiliary maintenance platform is slidably connected to the second track, and an auxiliary work surface is connected to the auxiliary maintenance platform. An auxiliary plate, flush with the height of the main work surface, is slidably connected to the auxiliary work surface. The first track and the two second tracks are arranged at right angles.
[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0009] 1. This utility model allows the main maintenance platform to slide freely on the first track, and the main platform on the main maintenance platform can rotate so that when it rotates to a right angle, it can be flush with the auxiliary platforms that slide from both sides, thus forming a larger and flatter operating area.
[0010] 2. By using the track between the main work surface and the main operating table, the rotating main work surface drives the collection bin in the track to push outward. While connecting with the auxiliary work surface, the dust and iron filings on the work surface are cleaned and collected into the collection bin by the brush plate. This allows the work surface to be cleaned at the same time as each rotation of the main work surface, which extends the usable area of the work surface. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0019] This utility model provides, for example Figures 1-5 The illustrated assembly workbench for aircraft generator maintenance includes a first track 1, a main maintenance platform 2, a main operating platform 3, a main work surface 4, a second track 5, an auxiliary maintenance platform 6, an auxiliary work surface 7, and an auxiliary plate 8. The main maintenance platform 2 is slidably connected to the first track 1. The main operating platform 3 is mounted on the main maintenance platform 2, and the main work surface 4 is mounted on the main operating platform 3. Second tracks 5 are located on both sides of the first track 1. The auxiliary maintenance platform 6 is slidably connected to the second track 5. The auxiliary work surface 7 is connected to the auxiliary maintenance platform 6, and the auxiliary plate 8, which is flush with the height of the main work surface 4, is slidably connected to the auxiliary work surface 7. The first track 1 and the two second tracks 5 on both sides are at right angles.
[0020] The main maintenance platform 2 can move freely on the track of track 1, increasing its usability. It can also cooperate with multiple auxiliary maintenance platforms 6 on track 2 to extend and expand the usable area of the main platform 4.
[0021] A slide rail 301 is provided between the main control panel 3 and the main table surface 4. A collection chamber 302 is slidably connected in the slide rail 301. There are two collection chambers 302, which are arranged opposite to each other. Multiple return springs 303 are connected between the two collection chambers 302. The main table surface 4 is connected to the knob 304 through the main control panel 3 via a shaft. A cam 305 is also connected between the main table surface 4 and the knob 304. The side of the cam 305 contacts the side of the collection chambers 302 on both sides.
[0022] Rotate the main platform 4 to align it with the auxiliary plates 8 on both sides, forming a flat work surface, which drives the rotation of the cam 305, thereby pushing the collection bin 302 in conjunction.
[0023] A brush plate 401 is fixedly connected to the bottom surface of the main table 4. The brush at the bottom of the brush plate 401 contacts the surface of the main operating table 3 and is used to clean iron filings from the surface of the main operating table 3. The main table 4 is coaxial with the cam 305 and rotates synchronously. The width of the main table 4 is approximately equal to the length of the auxiliary plates 8 on both sides. Both the main table 4 and the auxiliary plates 8 are made of stainless steel.
[0024] The two collection chambers 302 are pushed out of the main table 4 in a coordinated manner, and the dust and iron filings cleaned on the main operating table 3 during the rotation of the brush plate 401 are collected.
[0025] Working principle of this utility model:
[0026] Firstly, the main maintenance platform 2 can be expanded to a wider range of use via track 1, allowing it to be moved to the vicinity of the engine that needs maintenance. The main platform 4 on the main operating platform 3 can then be used to place and maintain the engine.
[0027] The usable area of the main maintenance platform 2 can also be expanded by cooperating with multiple No. 2 tracks 5. The No. 2 tracks 5 on both sides can also be used independently. When the main maintenance platform 2 needs to expand its area, the auxiliary platforms 7 on both sides need to be pushed to a position close to the main maintenance platform 2, such as... Figure 3 As shown;
[0028] By rotating the main platform 4, the original horizontal state with the main operating table 3 is changed to a vertical state with it, and the width of the main platform 4 corresponds to the long side of the auxiliary plates 8 on both sides. When the main platform 4 rotates, it drives the rotation of the cam 305, which pushes the two collection chambers 302 out of the slide rail 301 and extends them out of the main platform 4. When the brush plate 401 rotates synchronously with the main platform 4, the dust and iron filings left from the last maintenance operation are cleaned. The dust and iron filings are then collected in the collection chambers 302. At the same time, the wide side of the main platform 4 is in contact with and matches the long side of the auxiliary plates 8 on both sides, forming a wider usable area.
[0029] When the main platform 4 is rotated to a state where it is level with the main operating platform 3 and returns to its initial state, the two collection chambers 302 will also be stored in the main platform 4 under the action of the reset spring 303.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
