Description

TECHNICAL FIELD

[0001] The present application relates to the field of aero-engines, in particular to a simulation blade disassembling device. BACKGROUND

[0002] Fan pressurization stage is an important component of aero-engines. A large number of tests are needed before the design of fan pressurization stage is finalized. Figure 1 A super-speed test piece 90 of a fan pressurization stage is shown. Figure 2 A cross-sectional structure diagram of the super-speed test piece 90 is shown. The super-speed test piece 90 includes a pressurization stage drum disc 93 and simulation blades 91. The simulation blades 91 have dovetail tenons 92, and the pressurization stage drum is provided with corresponding annular dovetail mortises 94. The simulation blades 91 are installed into the mortises 94 of the pressurization stage drum through the tenons 92 and are positioned and rotationally stopped by locking blocks 97.

[0003] When the super-speed test piece 90 of the fan pressurization stage is disassembled, the simulation blades 91 need to slide to the gap 95 of the mortises 94 and then be taken out from the mortises 94. The super-speed test piece 90 usually needs to withstand a large centrifugal force and thermal stress when it is super-speeded. Under the influence of the centrifugal force and the thermal stress, there is usually a large tightness between the tenons 92 of the simulation blades 91 and the mortises 94 of the pressurization stage drum. A large tangential force is often needed to realize the disassembly of the simulation blades 91. However, the outer side of the simulation blades 91 is usually smooth, and it is difficult to directly apply a tangential force.

[0004] Generally, in order to disassemble the simulation blades 91, a rubber hammer can be used to hit the simulation blades 91 laterally, so as to generate a tangential component force to push the simulation blades 91 to slide along the annular mortises 94, thereby realizing the disassembly of the simulation blades. The use of the rubber hammer to hit the simulation blades 91 is easy to cause damage to the simulation blades 91 or the drum disc of the fan pressurization stage. SUMMARY

[0080] The present application will be more fully understood from the following detailed description taken in connection with the accompanying drawings, in which:

[0081] As Figures 3 to 6As shown, this embodiment is a simulated blade disassembly device 100. The simulated blade disassembly device 100 is used to disassemble the simulated blade 91 from the booster stage drum disk 93. The tenon 92 of the simulated blade 91 is engaged in the tenon 94 of the booster stage drum disk 93. The simulated blade disassembly device 100 includes: a base assembly 30, an extension assembly 40, and a clamping assembly 20. The base assembly 30 is connected to the rotor shaft 98. One end of the extension assembly 40 is pivotally mounted on the base assembly 30, and the other end of the extension assembly 40 extends radially outward along the rotor shaft 98 to the outside of the simulated blade 91. The clamping assembly 20 is connected to the extension assembly 40. The clamping assembly 20 is used to clamp the simulated blade 91. The extension assembly 40 is also used to apply a force to the clamping assembly 20 so as to push the simulated blade 91 to move through the clamping assembly 20. The clamping assembly 20 clamps the simulated blade 91, allowing force to be applied to the simulated blade 91 directly, preventing direct external force and damage. By connecting the base assembly 30 to the rotor shaft 98 and the extension assembly 40 to both the base assembly 30 and the clamping assembly 20, the extension assembly 40 can be rotated, thereby causing the clamping assembly 20 to rotate and moving the simulated blade 91. When the simulated blade 91 moves to the notch 95 of the tenon 94, it can be disassembled. The simulated blade disassembly device 100 avoids the use of a rubber mallet to strike the simulated blade 91, preventing damage from such impacts.

The tensioning member 23 is used to adjust the distance between the upper clamping plate 21 and the lower clamping plate 22 so that the clamping assembly 20 clamps the simulated blade 91. The clamping assembly 20, including the upper clamping plate 21, the lower clamping plate 22, and the tensioning member 23, has a simple structure and provides stable clamping.

[0091] The upper end of the axial extension rod 51 has a radial sliding seat 42, which is sleeved on the radial extension rod 41 and can move relative to the radial extension rod 41. The radial sliding seat 42 enables the axial extension rod 51 to move along the radial extension rod 41, so as to adjust the distance between the axial extension rod 51 and the rotor shaft 98, and thus facilitate the simulation vane disassembling device 100 to adapt to the disassembly of the simulation vanes 91 on the booster stage drum cylinder disc 93 with different diameters.

[0092] The simulation vane disassembling device 100 further comprises a radial stop 43, which is used to prevent the axial extension rod 51 from moving relative to the radial extension rod 41. The radial stop 43 fixes the axial extension rod 51 relative to the radial extension rod 41, so as to improve the stability and reliability of the simulation vane disassembling device 100 and avoid accidental movement of the axial extension rod 51.

[0093] The radial stop 43 can be a nut, and the outer periphery of the radial extension rod 41 is provided with a corresponding thread. The nut can be arranged on one side or both sides of the radial slide 42, and the nut abuts against the radial slide 42 to prevent the radial slide 42 from moving. In other embodiments, the radial stop 43 can also have other structural forms,

[0094] The simulation blade decomposition device 100 further comprises a first rotation-stopping shaft 44, which is arranged through the radial extension rod 41 and the axial extension rod 51, and is used to prevent the axial extension rod 51 from rotating relative to the radial extension rod 41. The first rotation-stopping shaft 44 prevents the axial extension rod 51 from rotating relative to the radial extension rod 41, thereby improving the stability and reliability of the simulation blade decomposition device 100 and avoiding accidental rotation of the axial extension rod 51.

[0095] The radial extension rod 41 has a radial extension groove 45, and the first rotation-stopping shaft 44 is arranged through the radial extension groove 45.

The gripping portion 46 facilitates the application of force and simplifies the operation difficulty of the simulation blade decomposition device 100.

[0098] The simulation blade decomposition device 100 further comprises a connecting sleeve 11, which has a first connecting hole 12 sleeved on the base assembly 30 and a second connecting hole 13 in which the extension assembly 40 is inserted. The axis of the first connecting hole 12 is perpendicular to the axis of the second connecting hole 13. The connecting sleeve 11 facilitates the connection of the base assembly 30 and the extension assembly 40, and has a simple structure and is easy to install. The connecting sleeve 11 can include two axis-perpendicular pipe fittings. In other embodiments, the connecting sleeve 11 can also have other structural forms.

[0099] The simulation blade disassembling device 100 further comprises an axial sliding seat 52, the axial sliding seat 52 is sleeved on the axial extension rod 51, the axial sliding seat 52 is movable relative to the axial extension rod 51, and the clamping assembly 20 is connected with the axial extension rod 51 through the axial sliding seat 52. The axial sliding seat 52 enables the clamping assembly 20 to move along the axial extension rod 51, so that the height of the clamping assembly 20 can be adjusted, and then the clamping assembly 20 can be connected with simulation blades 91 of different heights, and the operation simplicity of the simulation blade disassembling device 100 can be improved.

[0100] The simulation blade disassembling device 100 further comprises an axial stop 53, the axial stop 53 is used for preventing the clamping assembly 20 from moving relative to the axial extension rod 51. The axial stop 53 enables the clamping assembly 20 to be fixed relative to the axial extension rod 51, so that the stability and reliability of the clamping assembly 20 can be improved, and accidental movement of the clamping assembly 20 can be avoided.

[0101] The simulation blade disassembling device 100 further comprises a second rotation stop shaft 54, the second rotation stop shaft 54 is arranged through the clamping assembly 20 and the axial extension rod 51, and the second rotation stop shaft 54 is used for preventing the clamping assembly 20 from rotating relative to the radial extension rod 41.

The simulation blade disassembling device 100 can be adjusted in the radial direction and the axial direction, and can meet the disassembly of all simulation blades 91 of the three-stage fan supercharging stage. During the rotation of the simulation blade disassembling device 100, the simulation blade 91 can be pushed to rotate around the line of the rotor shaft 98, so that the simulation blade 91 is pushed to slide in the annular dovetail groove, and the lossless disassembly of the simulation blade 91 is realized.

[0105] The included angle assembly of the simulation blade disassembling device 100 can realize clamping of the simulation blade 91 by clamping the upper side 911 and the lower side 912 of the simulation blade 91.

[0117] The position of the radial slide 42 and the axial slide 52 is fixed by locking the radial stop 43 and the axial stop 53.

[0118] The tensioning member 23 is tightened, so that the upper clamp plate and the lower clamp plate clamp the upper side 911 and the lower side 912 of the to-be-disassembled simulation blade 91.
