Description

Technical Field

[0001] The present invention relates to the field of aero - engines, and particularly to a simulation blade disassembly device. Background Art

[0002] The fan booster stage is an important part of an aero - engine. A large number of tests are required before the fan booster stage is finalized in design. Figure 1 Shows a super - speed test piece 90 of a fan booster stage. Figure 2 Shows a schematic cross - sectional structure of the super - speed test piece 90. The super - speed test piece 90 includes a booster - stage drum disk 93 and simulation blades 91. The simulation blades 91 have dovetail - shaped tenons 92, and the booster - stage drum is provided with corresponding annular dovetail - shaped mortises 94. The simulation blades 91 are installed in the mortises 94 of the booster - stage drum through the tenons 92 and are positioned and locked against rotation by locking blocks 97.

[0003] When disassembling the super - speed test piece 90 of the fan booster stage, the simulation blades 91 need to slide to the notch 95 of the mortise 94 before they can be taken out of the mortise 94. When the super - speed test piece 90 undergoes super - speed rotation, it usually needs to withstand large centrifugal forces and thermal stresses. Under the influence of centrifugal forces and thermal stresses, there is often a large tightness between the tenons 92 of the simulation blades 91 and the mortises 94 of the booster - stage drum. Often, a large tangential force is required to achieve the disassembly of the simulation blades 91. However, the outer sides of the simulation blades 91 are usually relatively smooth, making it difficult to directly apply a tangential force.

[0004] Generally, in order to disassemble the simulation blades 91, a rubber hammer can be used to strike the simulation blades 91 laterally, thereby generating a tangential component force to push the simulation blades 91 to slide along the annular mortise 94, and then achieving the disassembly of the simulation blades. Striking the simulation blades 91 with a rubber hammer easily causes damage to the simulation blades 91 or the drum disk of the fan booster stage. Summary of the Invention

[0015] Preferably, the slideway is arc-shaped, and the center of the arc-shaped slideway coincides with the axis of the supercharging stage drum disc.

[0016] In this solution, by adopting the above structure, the moving direction of the impact block assembly is along the tangent direction of the simulated blade, facilitating the application of a force to the simulated blade.

[0017] Preferably, the slideway is a chute, the opening of the chute faces upward, and the impact block assembly is clamped in the chute.

[0018] In this solution, by adopting the above structure, the impact block assembly is clamped in the chute from top to bottom, facilitating the improvement of the stability of the impact block assembly and the reliability of movement, and avoiding the impact block assembly from disengaging from the chute.

[0019] Preferably, the base assembly has a receiving space, the receiving space extends along the length direction of the slideway, and both the clamping assembly and the impact block assembly extend into the receiving space.

[0020] In this solution, by adopting the above structure, the structure of the simulated blade decomposition device is made more compact.

[0021] Preferably, both ends of the base assembly are respectively arranged on the upper end face and the lower end face of the mortise groove, and the base assembly further includes a fixing member for fixing the base assembly to the tenon.

[0022] In this solution, by adopting the above structure, the stability of the base assembly can be improved.

[0023] Preferably, the base assembly further includes a buffer member provided between the base assembly and the mortise groove.

[0025] Preferably, the clamping assembly includes an upper clamping piece, a lower clamping piece and a tensioning member for adjusting the distance between the upper clamping piece and the lower clamping piece so that the clamping assembly clamps the simulated blade.

[0026] In this solution, by adopting the above structure, the clamping assembly includes an upper clamping piece, a lower clamping piece and a tensioning member, with a simple structure and stable clamping.

[0027] On the basis of conforming to the common knowledge in the art, the above preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0076] The present invention will be more clearly and completely described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments for this reason.

[0077] As Figures 3 to 10 shown, this embodiment is a simulation blade disassembly device 100 for disassembling a simulation blade 91 from a booster stage drum disc 93. The tenon 92 of the simulation blade 91 is clamped in the tenon groove 94 of the booster stage drum disc 93. The simulation blade disassembly device 100 includes: a clamping assembly 20, a base assembly 30, and a striker assembly 40. The clamping assembly 20 is used to clamp the simulation blade 91; the base assembly 30 is connected to the booster stage drum disc 93, and the base assembly 30 has a slideway 31; the striker assembly 40 is arranged on the slideway 31, the striker assembly 40 can move relative to the slideway 31, one side of the striker assembly 40 is used to contact the clamping assembly 20, and the other side of the striker assembly 40 is used to bear an external force to push the simulation blade 91 through the clamping assembly 20. The clamping assembly 20 is used to clamp the simulation blade 91, so that a force can be applied to the simulation blade 91 through the clamping assembly 20, avoiding directly applying an external force to the simulation blade 91 and preventing damage to the simulation blade 91. The base assembly 30 with the slideway 31 is used to connect the booster stage drum disc 93, and the striker assembly 40 can move along the slideway 31. Under the action of an external force on the striker assembly 40, the striker assembly 40 applies a force to the simulation blade 91 through the clamping assembly 20, thereby realizing the movement of the simulation blade 91. When the simulation blade 91 moves to the notch 95 of the tenon groove 94, the disassembly of the simulation blade 91 is realized. The simulation blade disassembly device 100 avoids hitting the simulation blade 91 with a rubber hammer and also avoids damage to the simulation blade 91 caused by hitting.

[0078] As Figure 5 and Figure 6 shown, the clamping assembly 20 includes an upper clip 21, a lower clip 22, and a tensioning member 23. The tensioning member 23 is used to adjust the distance between the upper clip 21 and the lower clip 22 so that the clamping assembly 20 clamps the simulation blade 91. The clamping assembly 20 includes an upper clip 21, a lower clip 22, and a tensioning member 23, with a simple structure and stable clamping.

[0079] In this embodiment, the upper clamping piece 21 includes an upper plate 211 and an upper barrel 212. The upper barrel 212 has an internal thread, and the axis of the upper barrel 212 is perpendicular to the upper plate 211. The lower clamping piece 22 includes an upper plate 211 and a lower barrel 222. The lower barrel 222 has an internal thread, and the axis of the lower barrel 222 is perpendicular to the lower plate 221. The helix direction of the internal thread of the upper barrel 212 is opposite to that of the internal thread of the lower barrel 222. The tensioning member 23 is a stud, and external threads with different helix directions are respectively provided at the upper end and the lower end of the stud. The stud is screwed into the upper barrel 212 and the lower barrel 222. By rotating the stud, the distance between the upper plate 211 and the lower plate 221 can be adjusted, so that the clamping assembly 20 can tightly clamp the upper side 911 and the lower side 912 of the simulated blade 91, and further the clamping assembly 20 and the simulated blade 91 become an integral body. The tangential decomposition force required by the simulated blade 91 can be transmitted to the simulated blade 91 through the clamping assembly 20.

[0080] In other embodiments, the clamping assembly 20 can also be of other structures, such as a fixture that can directly clamp the upper side 911 and the lower side 912 of the simulated blade 91, or a component directly adhered to the simulated blade 91. The clamping assembly 20 can achieve relative fixation with the simulated blade 91 and is convenient for applying the decomposition force.

[0081] As Figure 9 shown, the figure shows a schematic diagram of the base assembly 30 being installed on the overspeed test piece 90. In the figure, the slideway 31 is arc-shaped, and the center of the arc-shaped slideway 31 coincides with the axis of the booster stage drum disc 93, so that the moving direction of the striker assembly 40 is along the tangent direction of the simulated blade 91, which is convenient for applying a force to the simulated blade 91.

[0082] The slideway 31 is a chute 32, the opening of the chute 32 faces upward, and the striker assembly 40 is clamped in the chute 32. The striker assembly 40 is clamped in the chute 32 from top to bottom, which is convenient for improving the stability of the striker assembly 40 and the reliability of the movement, and avoiding the striker assembly 40 from detaching from the chute 32.

[0083] In this embodiment, the cross-section of the chute 32 is a "U"-shaped groove, and the striker assembly 40 is clamped in the "U"-shaped groove. The striker assembly 40 can slide along the "U"-shaped groove. In other embodiments, the slideway 31 can also be of other forms, such as a dovetail groove on the outer side of the opening, a track formed by an I-beam, etc. The slideway 31 can support or suspend the striker assembly 40 and guide the striker assembly 40.

[0084] The base assembly 30 has a receiving space 33, and the receiving space 33 extends along the length direction of the slideway 31. Both the clamping assembly 20 and the striker assembly 40 extend into the receiving space 33, making the structure of the simulated blade decomposition device 100 more compact.

[0085] Both ends of the base assembly 30 are respectively arranged on the upper end surface 941 and the lower end surface 942 of the mortise groove 94. The base assembly 30 further includes a fixing member 34, and the fixing member 34 is used to fix the base assembly 30 to the tenon 92, which can improve the stability of the base assembly 30.

[0086] The base assembly 30 may further include a buffer member, and the buffer member is arranged between the base assembly 30 and the mortise groove 94. It can prevent the base assembly 30 from damaging the tenon 92, and can also improve the stability of the base assembly 30 and prevent the base assembly 30 from accidentally moving. The buffer member can be made of soft materials, such as rubber skin, copper skin, silicone skin, or can also be regarded as other composite materials.

[0087] As an implementation manner, the base assembly 30 may include a base frame 35. The cross-section of the base frame 35 may be an inverted "U" - shaped frame, and the opening of the "U" - shaped frame faces the overspeed test piece 90. The "U" - shaped frame is clamped on the upper end surface 941 and the lower end surface 942 of the mortise groove 94. The "U" - shaped frame is integrally fan - shaped, and the center of the fan coincides with the axis of the overspeed test piece 90.

[0088] The base assembly 30 may further include a fixing member 34, and the fixing member 34 fixes the "U" - shaped frame to the overspeed test piece 90. The fixing member 34 may specifically be a bolt. The upper side wall of the "U" - shaped frame is provided with a threaded hole, and the bolt is screwed into the threaded hole, and the lower end of the bolt abuts against the upper end surface 941 of the mortise groove 94. In other embodiments, the fixing member 34 may also be other components, such as a spring, a wedge plug, etc. arranged between the "U" - shaped frame and the mortise groove 94. The slideway 31 is arranged on the top surface of the upper side wall of the "U" - shaped frame. The accommodating space 33 is arranged on the left side surface of the "U" - shaped frame. Both the clamping assembly 20 and the impact block assembly 40 extend into the accommodating space 33.

[0089] In other embodiments, the base assembly 30 may also be installed on the overspeed test piece 90 through other structures, which can clamp the overspeed test piece 90, provide a support or suspension point for the impact block assembly 40, and guide the impact block assembly 40.

[0090] The impact block assembly 40 includes an impact block 41 and a sliding member 42. The impact block 41 is arranged on the slideway 31 through the sliding member 42. One side of the impact block 41 is used to contact the clamping assembly 20, and the impact block 41 is used to bear an external force. The sliding member 42 can reduce the resistance of the impact block 41 moving in the slideway 31, so that the external force can be more efficiently converted into the power to push the simulation blade 91. The external force can come from hammering, a linear driving member, etc.

[0091] The slider 42 includes a mounting plate 421, rolling elements 422 and a retaining member 423. The slider 42 is connected to the impact block 41 through the mounting plate 421. The rolling elements 422 are clamped between the mounting plate 421 and the retaining member 423. Part of the rolling elements 422 are exposed from the retaining member 423, and the rolling elements 422 are in contact with the slideway 31. The slider 42 includes a mounting plate 421, rolling elements 422 and a retaining member 423, with a simple structure and reliable use. In this embodiment, both the mounting plate 421 and the retaining member 423 can be arc-shaped plates. The arc-shaped plates are provided with accommodation holes for accommodating the rolling elements 422. A plurality of accommodation holes are arranged at intervals, and the rolling elements 422 are correspondingly arranged. The rolling elements 422 can specifically be steel balls or steel columns. The rolling elements 422 can roll freely in the slideway 31. The mounting plate 421 and the retaining member 423 can also be connected by fasteners 44. The slider 42 and the impact block 41 can also be connected by fasteners 44.

[0092] The impact block assembly 40 further includes a connecting member 43. The connecting member 43 is arranged between the slider 42 and the impact block 41, and the connecting member 43 extends from the slideway 31 towards the clamping assembly 20. The connecting member 43 facilitates the flexible adjustment of the position of the impact block 41, so that the impact block assembly 40 can not only meet the placement of the slideway 31 but also meet the impact on the clamping assembly 20.

[0093] In this embodiment, the impact block 41 can be a rectangular metal block. The connecting member 43 can be an "L"-shaped plate. One end of the "L"-shaped plate is connected to the impact block 41, and the other end of the "L"-shaped plate is connected to the slider 42. The impact block assembly 40 is installed on the slideway 31 in an inverted hook shape.

[0094] The simulation blade decomposition device 100 utilizes the upper side surface 911 and the lower side surface 912 of the simulation blade 91 to set the clamping assembly 20. Under the fixation of the locking block 97, the simulation blade 91 is set at the locking position 96, so that the clamping assembly 20 and the simulation blade 91 become an integral body, and an external force can be directly applied to the clamping assembly 20 to push the simulation blade 91 to rotate. The fixing of the base assembly 30 on the booster stage drum disc 93 is realized by using the upper end surface 941 and the lower end surface 942 of the clamping tenon groove 94. After installation, the arc-shaped chute 32 on the base assembly 30 is coaxial with the booster stage drum disc 93. The impact block assembly 40 is installed in the arc-shaped chute 32 of the base assembly 30 and can move in the chute 32. During the movement of the impact block assembly 40, it collides with the clamping assembly 20, and the inertial force generated by repeated collisions is consistent with the annular tangential direction formed by the simulation blade 91, thereby pushing the simulation blade 91 to slide in the tenon groove 94. When the simulation blade 91 slides to the notch 95, the non-destructive decomposition of the simulation blade 91 can be realized.

[0095] By setting the clamping assembly 20 on the upper side surface 911 and the lower side surface 912 of the simulation blade 91, the decomposition force is transmitted through the clamping assembly 20 to realize the decomposition of the simulation blade 91.

[0096] The base assembly 30 is fixed on the supercharging stage drum disc 93 by means of the upper end face 941 and the lower end face 942 of the clamping tenon groove 94. An arc-shaped slideway 31 is provided on the base assembly 30. After the base assembly 30 is installed, the axis of the arc-shaped slideway 31 is coaxial with the fan supercharging stage drum disc 93.

[0097] The striker assembly 40 can slide back and forth in the arc-shaped slideway 31 of the base assembly 30 and repeatedly strike the clamping assembly 20 fixed on the simulated blade 91. The generated inertial force is exactly consistent with the annular tangential direction formed by the simulated blade 91, so as to meet the external force requirements for the decomposition of the simulated blade 91, and there is no component force in the radial direction for this external force, and thus the non-destructive decomposition of the simulated blade 91 can be realized.

[0098] An arc-shaped accommodation space 33 is provided on the base assembly 30. The connecting piece 43 and the impact block 41 form a reverse hook shape, so that they can penetrate into the accommodation space 33 and strike the clamping assembly 20 of the simulated blade 91 to generate an inertial force.

[0099] The striker assembly 40 is provided with a plurality of rolling elements 422. The rolling elements 422 can specifically be rolling balls. The rolling balls roll freely in the arc-shaped chute 32 of the base. The friction of the rolling balls is small, so as to reduce the movement resistance of the striker assembly 40 in the arc-shaped chute 32 of the base assembly 30 and avoid jamming.

[0100] The simulated blade decomposition device 100 can generate the tangential force required for the decomposition of the simulated blade and avoid generating radial force, realize the non-destructive decomposition of the simulated blade 91, and improve the safety of the decomposition process. The principle of the simulated blade decomposition device 100 is simple, the structure is simple, and the manufacturing and maintenance costs are relatively low.

[0101] As an implementation manner, the simulated blade decomposition device 100 can be installed according to the following steps.

[0102] As shown in Figure 5 and Figure 6 , rotate the tensioning member 23, that is, rotate the double-headed stud, so that the upper clamping piece 21 and the lower clamping piece 22 clamp the upper end face 941 and the lower end face 942 of the simulated blade 91, and realize the fixation of the clamping assembly 20 on the simulated blade 91.

[0103] As shown in Figure 9 , by tightening the fastener 44, the fan-shaped base assembly 30 is fixed on the upper end face 941 and the lower end face 942 of the tenon groove 94 of the fan supercharging stage drum disc 93.

[0104] As shown in Figure 7 and Figure 8 , the installation of the striker assembly 40 is completed.

[0105] Install the impact block 41 assembly into the chute 32 of the base assembly 30, and simulate the installation form of the blade disassembly device 100 on the overspeed test piece 90 as Figure 10 shown.

[0106] Repeatedly toggle the striker assembly 40 so that the striker assembly 40 repeatedly impacts the clamping assembly 20. The generated inertial force pushes the simulated blade 91 to rotate until the simulated blade 91 is pushed to the notch 95 of the mortise 94, completing the disassembly of the simulated blade 91.

[0107] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
