Description

Technical Field

[0001] This invention belongs to the technical field of aero-engine testing devices, specifically relating to a component testing device for aero-engines. Background Technology

[0002] Aero engines primarily consist of the following core components: compressor blades and fan blades. As cold-end components, they are mainly responsible for compressing the air entering the engine. The blades must withstand complex loads such as centrifugal force, aerodynamic forces, and thermal stress, requiring extremely high precision in controlling their surface torsion and thickness. Titanium alloys, due to their low specific gravity and strong corrosion resistance, have become the primary material for compressor blades.

[0003] Turbine blades, being hot-end components, operate under high temperature and high pressure environments. They convert the chemical energy of combustion gases into mechanical energy through expansion and decompression, making them the most challenging to manufacture. Materials must possess high-temperature resistance and fatigue resistance, commonly using high-temperature alloys or silicon nitride ceramics. Aerospace bearings, serving as supporting components between the rotor and the casing, must withstand extremely high speeds and axial or radial loads.

[0004] The wiring in an aircraft engine primarily serves to control and transmit signals. Within the engine, wiring connects various sensors and actuators, responsible for monitoring various engine parameters and controlling the engine's operating status.

[0005] When engine circuits are put into actual operation, their physical properties, chemical properties, and other properties need to be tested. In the process of testing multiple properties, two different devices are required. For example, when it is necessary to test the acid resistance or alkali resistance of the circuit under different pressures, the existing equipment often requires separate devices to conduct independent pressure resistance or acid resistance tests. The functionality is relatively limited, and the equipment can only adjust a single variable. It cannot simultaneously test multiple properties of the circuit by adjusting multiple variables at the same time, which affects the improvement of the equipment's applicability. Summary of the Invention

[0006] The purpose of this invention is to provide a component testing device for aero-engines to solve the technical problem that existing equipment has limited functionality and can only adjust a single variable, failing to simultaneously test multiple performance parameters of the circuit through the simultaneous change of multiple variables, thus affecting the improvement of the equipment's applicability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A component inspection device for aircraft engines, comprising:

[0009] A tensile testing mechanism includes side plates placed at both ends of a base plate. A motor is fixedly installed on the side plates. The output shaft of the motor extends to a reciprocating screw. Both ends of the reciprocating screw are helically driven by a first slider that moves in the opposite direction. One end of the first slider extends to a guide post between the side plates, and a telescopic sleeve is fixedly connected to the other end.

[0010] One end of the telescopic sleeve is fixed to the side plate, and the other end is provided with a positioning hole and a line is fixed by a positioning bolt. The protrusions at both ends of the first slider and the second slider at the extension end of the side plate are connected by a first swing rod. The second slider is connected with a groove along the length of the side plate, and one end of the second slider is connected with an extrusion plate symmetrical about the center of the line. The extrusion plates are configured to have extrusion cavities connected to the line.

[0011] Furthermore, it also includes a sealing detection mechanism, which includes electric guide rails fixed on both sides of the top of the base plate. U-shaped blocks are slidably connected on the electric guide rails. The U-shaped blocks are fixedly connected to each other by a crossbeam. A water tank is connected to the top of the U-shaped blocks by a bracket. A first cylinder adapted to the first cylinder is installed on the crossbeam. The piston rod of the first cylinder passes through the water tank and extends to the line through a hook.

[0012] Furthermore, both ends of the piston rod on the first cylinder are integrally formed with push blocks. The bottom of the push blocks movably abuts against the sealing plate. The bottom of the sealing plate and the side wall of the water tank are connected by a first spring. One end of the opening on the sealing plate extends into the liquid storage box on the outer wall of the water tank. A second cylinder and a conduit are respectively installed on the top of the liquid storage box. The piston rod on the second cylinder extends to the panel on the inner wall of the liquid storage box.

[0013] Furthermore, the panel has filter holes that are adapted to it, and one end of the panel passes through the first partition and extends to the side wall of the second partition via a bracket. A third cylinder is fixedly installed on the bracket, and the piston rod of the third cylinder is connected to a fixed rod located below the panel. One end of the fixed rod has an inclined surface.

[0014] Furthermore, a baffle plate placed on the filter hole is connected to the bottom of the panel by a second spring. One end of the baffle plate is provided with an inclined groove corresponding to the inclined surface near the fixed rod. One end of the inclined groove is provided with a concave hole extending into the interior of the baffle plate. An inclined plate connected to the opening on the sealing plate is provided below the baffle plate. A metering cavity is formed between the inclined plate, the baffle plate and the side wall of the liquid storage box.

[0015] Furthermore, a pushing assembly is connected to the piston rod on the second cylinder via a bending rod and positioned between the first and second partitions. The pushing assembly includes a first gear plate fixed on the bending rod, a second gear plate whose outer wall of the first gear plate moves in the opposite direction via a first gear meshing transmission, and the extended end of the second gear plate extends to a movable plate between the second partition and the inner wall of the liquid storage box. The first and second partitions are connected by an inclined tube.

[0016] Furthermore, the mounting holes of the piston rod on the bracket and the third cylinder near the first partition are both telescopic structures, and a control valve adapted to them is installed on the guide tube.

[0017] Furthermore, the piston rod on the first cylinder is connected to the moving block at both ends by a second swing rod. One end of the moving block is connected to a third gear plate placed inside the housing. The outer wall of the third gear plate is meshed with a second rotating tooth. The central shaft on the second rotating tooth is fixed to a first bevel gear. The outer wall of the first bevel gear is meshed with a second bevel gear fixed to a movable shaft. Stirring rods can be detachably installed at both ends of the movable shaft.

[0018] Furthermore, both ends of the second swing rod are mounted on the first cylinder and the moving block by means of a rotatable connection, and both ends of the housing are fixed to the inner wall of the water tank by mounting rods.

[0019] Furthermore, both ends of the first swing rod are mounted on the first and second sliders by means of a rotatable connection, and one end of the telescopic sleeve is fixed to the side plate.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) In this invention, when performing tensile testing on the circuit, the two ends of the circuit are first connected to the positioning holes of the telescopic sleeve. At this time, the motor starts and drives the reciprocating screw to rotate. Under the action of the screw drive, the first slider at both ends drives the circuit to perform tensile strength testing. The telescopic sleeve can not only fix the circuit, but also ensure the normal horizontal movement of the first slider through the free telescopic structure design. When the first slider moves outward, under the action of the rotation connection of the first swing rod, it can drive the extrusion plate to perform centering extrusion on the circuit, thereby enabling the corresponding detection of the hardness of the circuit, effectively improving the detection quality and having strong application performance.

[0022] (2) In this invention, water is preferentially introduced into the water tank. Under the action of the first cylinder, the hook drives the cable downward to the water tank, thereby allowing the sealing performance of the cable at the corresponding position to be tested. At the same time, during the downward push of the first cylinder, the push block abuts against the sealing plate and moves downward synchronously, thereby opening the opening on the sealing plate, allowing the acidic or alkaline liquid in the storage box to be introduced into the water tank, thereby increasing the corresponding acidity or alkalinity of the water. In addition, during the up-and-down movement of the panel, the second cylinder can change the volume of the metering chamber, and in conjunction with the third cylinder, the filtered liquid can be... As the liquid is introduced into the metering chamber, the upward movement of the panel signifies an increase in the volume of the metering chamber. Under the meshing transmission of gears, the movable plate moves upward, promptly replenishing the metering chamber with liquid from the storage box. During the activation of the third cylinder, the horizontal movement of the fixed rod, combined with the action of the moving contact, causes the baffle plate to move downward, opening or closing the filter holes. This effectively controls the volume of acidic or alkaline liquid in the metering chamber, allowing for the detection of the circuit's acid and alkali resistance at different pressures. This significantly improves the equipment's functionality and provides excellent testing results.

[0023] (3) In this invention, when the acidic or alkaline solution is introduced into the water tank, the second swing rod drives the third gear plate to move horizontally within the housing. Under the action of gear meshing transmission, the horizontal force is converted into a vertical force, thereby transmitting the force to the movable shaft. The movable shaft can then drive the stirring rods at both ends to rotate synchronously, so that the acidic and alkaline solutions are fully mixed with the water, thereby stably increasing the corresponding acid or alkaline value in the liquid, effectively increasing the stability and safety of the device.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference manual attached Figure 1 -Appendix Figure 9As shown, a component inspection device for an aircraft engine includes:

[0038] Tensile testing mechanism 1 includes side plates 2 placed at both ends of the base plate. A motor 3 is fixedly installed on the side plates 2. The output shaft of the motor 3 extends to the reciprocating screw 4. Both ends of the reciprocating screw 4 are helically driven by a first slider 5 that moves in the opposite direction. One end of the first slider 5 extends to the guide post 6 between the side plates 2, and the other end is fixedly connected to a telescopic sleeve 7.

[0039] When performing tensile testing on the circuit, the two ends of the circuit are first connected to the positioning holes of the telescopic sleeve 7. At this time, the motor 3 starts and drives the reciprocating screw 4 to rotate. Under the action of screw transmission, the first sliders 5 at both ends drive the circuit to perform tensile strength testing. The telescopic sleeve 7 can not only fix the circuit, but also ensure the normal horizontal movement of the first slider 5 through the free telescopic structure design. When the first slider 5 moves outward, under the action of the rotation connection of the first swing rod 9, it can drive the extrusion plate 10 to perform centering extrusion on the circuit, thereby enabling the corresponding detection of the circuit's hardness, effectively improving the detection quality and demonstrating strong application performance.

[0040] One end of the telescopic sleeve 7 is fixed to the side plate 2, and the other end is provided with a positioning hole and a line is fixed by a positioning bolt. The protrusions at both ends of the first slider 5 and the second slider 8 at the extension end of the side plate 2 are connected by the first swing rod 9. The second slider 8 is connected with a sliding groove along the length of the side plate 2, and one end of the second slider 8 is connected to an extrusion plate 10 symmetrical about the center of the line. The extrusion plates 10 are configured to have extrusion cavities connected to the line.

[0041] Specifically, during the rotation of the reciprocating screw 4, the first sliders 5 at both ends can move in the opposite direction on the guide post 6, thereby detecting the tensile strength performance of the circuit through external movement. The second slider 8 is movably connected to the horizontal extension end on the side plate 2. Under the rotational connection of the first swing rod 9, it can drive the extrusion plates 10 at both ends to perform centering extrusion work simultaneously. Therefore, when performing tensile strength testing on the circuit, its hardness can also be tested accordingly, resulting in good testing effect and expanding the applicability of the device.

[0042] The positioning hole on the telescopic sleeve 7, in conjunction with the positioning bolt, can lock and fix the line in the positioning hole through a threaded connection, thereby effectively fixing it on the telescopic sleeve 7.

[0043] A component testing device for an aircraft engine also includes a sealing testing mechanism 11. The sealing testing mechanism 11 includes electric guide rails 12 fixed on both sides of the top of the base plate. U-shaped blocks 13 are slidably connected on the electric guide rails 12. The U-shaped blocks 13 are fixedly connected to each other by a crossbeam. A water tank 14 is connected to the top of the U-shaped blocks 13 by a bracket. A first cylinder 15 adapted to the first cylinder 14 is installed on the crossbeam. The piston rod of the first cylinder 15 passes through the water tank 14 and extends to the wiring through a hook 16.

[0044] Both ends of the piston rod on the first cylinder 15 are integrally connected to push blocks 17. The bottom of the push blocks 17 moves and abuts against the sealing plate 18. The bottom of the sealing plate 18 and the side wall of the water tank 14 are connected by a first spring 19. One end of the opening on the sealing plate 18 extends into the liquid storage box 20 on the outer wall of the water tank 14. The top of the liquid storage box 20 is respectively equipped with a second cylinder 21 and a conduit 22. The piston rod on the second cylinder 21 extends to the panel 23 on the inner wall of the liquid storage box 20.

[0045] The panel 23 has a filter hole 24 that is compatible with it, and one end of the panel 23 passes through the first partition 25 through the bracket and extends to the side wall of the second partition 26. A third cylinder 27 is fixedly installed on the bracket. The piston rod of the third cylinder 27 is connected to a fixed rod 28 located below the panel 23. One end of the fixed rod 28 has an inclined surface.

[0046] Water is preferentially introduced into water tank 14. Under the action of the first cylinder 15, the hook 16 moves the cable downward into water tank 14, allowing the sealing performance of the cable at the corresponding location to be checked. Simultaneously, as the first cylinder 15 pushes downward, the push block 17 abuts against and moves downward synchronously onto the sealing plate 18, opening the opening on the sealing plate 18 and allowing acidic or alkaline liquid from the storage box 20 to be introduced into water tank 14, thereby increasing the corresponding acidity or alkalinity of the water. Furthermore, as the second cylinder 21 moves the panel 23 up and down, it can change the volume of the metering chamber, which, in conjunction with the third cylinder 27, can release the filtered liquid. As liquid is introduced into the metering chamber, the upward movement of panel 23 indicates an increase in the volume of the metering chamber. Under the meshing transmission of gears, movable plate 39 moves upward, thus replenishing the metering chamber with liquid from storage box 20. During the activation of the third cylinder 27, the horizontal movement of fixed rod 28, combined with the action of moving contact, drives baffle plate 30 downward, opening or closing filter hole 24. This effectively controls the volume of acidic or alkaline liquid in the metering chamber, allowing for the detection of the circuit's acid and alkali resistance at different pressures, effectively improving the equipment's functionality and providing excellent testing results.

[0047] Specifically, the water in the water tank 14 has multiple functions. For example, with the help of the electric guide rail 12 and the hook 16, the cable can be pulled into the water tank 14 for sealing testing, thereby detecting the sealing performance of the cable. In addition, water can be poured into the water tank 14 first, and then the acidic or alkaline liquid in the storage box 20 can be gradually added to increase the acidity or alkalinity of the solution, thus adaptably changing the pH value of the solution in the water tank 14.

[0048] Furthermore, for those skilled in the art, during the dilution of hydrochloric acid, if water is poured into concentrated hydrochloric acid, a small amount of hydrogen chloride gas may be generated due to the evaporation of hydrochloric acid, which poses a certain danger. Therefore, the present invention introduces hydrochloric acid into water. Since the density of concentrated hydrochloric acid is close to that of water, less heat is released during dilution, and it usually does not cause danger. The above-mentioned operation method is a conventional technical means for those skilled in the art, and will not be described in detail here, nor will it affect the implementation of the technical solution of the present invention.

[0049] The bottom of panel 23 is connected to a baffle plate 30 placed on filter hole 24 via a second spring 29. One end of the baffle plate 30 is provided with a groove 31 corresponding to the inclined surface near the fixing rod 28. One end of the groove 31 is provided with a concave hole 32 extending into the interior of the baffle plate 30. Below the baffle plate 30 is an inclined plate 33 connected to the opening on the sealing plate 18. A metering cavity is formed between the inclined plate 33, the baffle plate 30 and the side wall of the liquid storage box 20.

[0050] When the inclined surface abuts against the inclined groove 31, due to the action of the movable abutment, under the elastic action of the second spring 29, the baffle plate 30 moves downward and provides a stable limiting space for the fixing rod 28 through the concave hole 32, so that the baffle plate 30 is fixed at the corresponding height position, thereby allowing the liquid to flow steadily into the metering chamber.

[0051] By changing the volume of the metering chamber, the volume of acidic or alkaline liquid in the chamber can be determined, thereby altering the acidity and alkalinity during the dilution process. This allows for control over the different pH values ​​of different solutions, which is beneficial for the stable conduct of the experiment.

[0052] The piston rod on the second cylinder 21 is connected by a bending rod 34 to a pushing assembly 35 located between the first partition 25 and the second partition 26. The pushing assembly 35 includes a first gear plate 36 fixed on the bending rod 34, and a second gear plate 38 that moves in the opposite direction through the meshing of the outer wall of the first gear plate 36 with the first rotating teeth 37. The extended end of the second gear plate 38 extends to the movable plate 39 between the second partition 26 and the inner wall of the liquid storage box 20. The first partition 25 and the second partition 26 are connected by an inclined tube 40. The mounting holes of the support and the piston rod on the third cylinder 27 near the first partition 25 are all telescopic structures, and a control valve adapted to them is installed on the conduit 22.

[0053] Extending this further, the piston rod on the third cylinder 27 is also designed with a telescopic structure at the connection of the first partition 25. This facilitates the normal up-and-down movement of the transmission components and ensures the sealing of the connection of the structural components, thereby effectively guiding the liquid into the metering chamber.

[0054] The piston rod on the first cylinder 15 is connected to the moving block 41 by the second swing rod 42. One end of the moving block 41 is connected to the third gear plate 44 located inside the housing 43. The outer wall of the third gear plate 44 is meshed with the second rotating tooth 45. The central shaft on the second rotating tooth 45 is fixed on the first bevel gear 46. The outer wall of the first bevel gear 46 is meshed with the second bevel gear 47 fixed on the movable shaft. The stirring rod 48 can be detachably installed at both the upper and lower ends of the movable shaft.

[0055] Specifically, both ends of the second swing rod 42 are mounted on the first cylinder 15 and the moving block 41 by means of rotational connection, both ends of the housing 43 are fixed to the inner wall of the water tank 14 by means of mounting rods, both ends of the first swing rod 9 are mounted on the first slider 5 and the second slider 8 by means of rotational connection, and one end of the telescopic sleeve 7 is fixed to the side plate 2.

[0056] When an acidic or alkaline solution is introduced into the water tank 14, the second swing rod 42 drives the third gear plate 44 to move horizontally within the housing 43. Under the action of gear meshing transmission, the horizontal force is converted into a vertical force, which is then transmitted to the movable shaft. The movable shaft can then drive the synchronous rotation of the stirring rods 48 at both ends, thereby allowing the acidic and alkaline solutions to fully mix with the water. This can stably increase the corresponding acidity or alkalinity value in the liquid, effectively increasing the stability and safety of the device.
