Description

Technical Field

[0001] This utility model relates to the field of aircraft trailing edge flap valve assembly maintenance technology, and in particular to an aircraft trailing edge flap valve assembly positioning device. Background Technology

[0002] The trailing edge flap valve assembly is a critical component of an aircraft system, its primary function being to control the movement of the trailing edge flaps to adjust the aircraft's lift and drag. Pilots control the trailing edge flaps via a joystick or electronic control system. In modern aircraft, the movement of the trailing edge flaps is driven by an electro-hydraulic servo system controlled by the valve assembly. The pilot's input signals are transmitted to the valve assembly via control circuitry, which regulates the flow of hydraulic fluid, thereby actuating the trailing edge flaps. Existing trailing edge flap valve assemblies, such as... Figure 1 As shown, the valve assembly 100 includes a valve body 110, a valve core 120, and a mounting plate 130. One end of the valve core 120 is located inside the valve body 110 and is slidably connected to the valve body 110. The valve core 120 can move along its own axial direction relative to the valve body 110, and the valve core 120 can also rotate around its own axis relative to the valve body 110. A through hole 121 extending radially is provided on the other end of the valve core 120. The mounting plate 130 is fixedly sleeved on the valve body 110 and coaxially arranged with the valve core 120 to separate the valve body 110 into a front side and a rear side. The protruding end of the valve core 120 is located on the front side of the valve body 110. The mounting plate 130 has multiple mounting holes 131. By supplying hydraulic oil into the valve body 110, the valve core 120 can be driven to reciprocate along its own axial direction to adjust the protruding length of the valve core 120. When overhauling the trailing edge flap valve assembly, first use a positioning fixture to position the valve assembly, then fill the valve body with hydraulic oil to pressurize the valve body, and then drive the valve core to move back and forth along its own axis through an external drive component to make the valve core reach different extension lengths. Measure the pressure value in the valve body when the valve core is at different extension lengths to determine whether the valve assembly meets the requirements.

[0003] Existing valve assembly positioning fixtures (such as the pressure valve assembly assembly fixture disclosed in application number 201721859563.1) are not suitable for positioning the trailing edge flap valve assembly with the above structure and cannot adjust the extension length of the valve core in real time. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a positioning device for an aircraft trailing edge flap valve assembly. This solves the technical problem that there is no suitable positioning fixture in the prior art that can position the trailing edge flap valve assembly of the above structure and adjust the extension length of the valve core in real time.

[0005] To achieve the above technical objectives, the present invention provides a positioning device for an aircraft trailing edge flap valve assembly, comprising:

[0006] A positioning mechanism includes a positioning plate and a first connecting member. The positioning plate has a positioning opening for the front side of the valve body of the valve assembly to slide through. The first connecting member is detachably connected to the positioning plate and the mounting plate of the valve assembly.

[0007] An adjustment mechanism is provided for detachably connecting to the protruding end of the valve core of the valve assembly and for driving the valve core to reciprocate along its axial direction to adjust the protruding length of the valve core.

[0008] Furthermore, the positioning plate is provided with a plurality of first connecting holes and a plurality of first connecting members. When the front side of the valve body slides through the positioning port, each of the first connecting holes corresponds one-to-one with each of the mounting holes on the mounting plate. Each of the first connecting members slides one-to-one through each of the first connecting holes and the corresponding mounting holes, and can be detachably connected to the positioning plate and the mounting plate.

[0009] Furthermore, the first connector includes a first stud and two first nuts. The first stud slides through the first connecting hole and the corresponding mounting hole. The two first nuts are both sleeved on the first stud and are threadedly connected to the first stud. The end faces of the two first nuts abut against the side wall of the positioning plate and the side wall of the mounting plate, respectively.

[0010] Furthermore, the adjustment mechanism includes a docking block, a second connecting member, and a driving member. The docking block has an insertion hole at one end near the positioning plate. The insertion hole is coaxially arranged with the positioning port and is used to allow the protruding end of the valve core to slide into it. The second connecting member is detachably connected to the docking block and the valve core. The driving member is connected to the docking block and is used to drive the docking block to reciprocate along the axial direction of the valve core to adjust the protruding length of the valve core.

[0011] Furthermore, a second connecting hole is provided on one end of the docking block near the positioning plate. The second connecting hole extends radially along the insertion hole and penetrates the insertion hole. When the protruding end of the valve core is slidably inserted into the insertion hole, the second connecting hole corresponds to the through hole on the valve core. The second connector slides through the second connecting hole and the through hole and can detachably connect the docking block and the valve core.

[0012] Furthermore, the second connector includes a second stud and two second nuts. The second stud slides through the second connecting hole and the through hole. The two second nuts are both sleeved on the second stud and are threadedly connected to the second stud. The end faces of the two second nuts abut against the two opposite side walls of the mating block, respectively.

[0013] Furthermore, the adjustment mechanism also includes a support plate with a screw hole coaxially arranged with the insertion hole. The driving component includes a bushing, a shaft core, and a screw. The bushing is coaxially arranged with the insertion hole and is detachably fixed to the end of the mating block away from the positioning plate via a screw. The shaft core is rotatably disposed within the bushing. One end of the screw rotatably extends into the bushing and is coaxially fixedly connected to the shaft core. The other end of the screw passes through the screw hole and is threadedly connected to the screw hole.

[0014] Furthermore, the aforementioned aircraft trailing edge flap valve assembly positioning device also includes a limiting mechanism connected to the docking block, which is used to limit the rotation of the docking block.

[0015] Furthermore, the limiting mechanism includes two limiting plates and a limiting shaft. The two limiting plates are disposed opposite to each other on both sides of the adjusting mechanism and extend along the moving direction of the docking block. A limiting hole is provided on the end of the docking block away from the positioning plate. The limiting hole extends radially along the insertion hole. The limiting shaft slides through the limiting hole, and both ends of the limiting shaft are slidably connected to the two limiting plates respectively.

[0016] Furthermore, the limiting plate has a first vertical section, a horizontal section and a second vertical section connected sequentially from bottom to top, and the end of the limiting shaft rests on the horizontal section and slides against the side wall of the second vertical section.

[0017] Compared with the prior art, the beneficial effects of this utility model include: when overhauling the valve assembly, the front side of the valve body is slid through the positioning port, and the positioning plate and mounting plate are detachably connected through the first connector, thereby positioning and fixing the valve assembly. Then, the adjusting mechanism is detachably connected to the protruding end of the valve core. Hydraulic oil is injected into the valve body through the external hydraulic oil circuit system, so that the valve body is in a pressurized state. The valve core is driven to move back and forth along its axis by the adjusting mechanism, thereby adjusting the protrusion length of the valve core. The pressure value in the valve body is measured by the external pressure testing system when the valve core is at different protrusion lengths, so as to determine whether the valve assembly meets the requirements based on the pressure value. This aircraft trailing edge flap valve assembly positioning device is suitable for use when positioning the trailing edge flap valve assembly of this structure, and can adjust the protrusion length of the valve core in real time.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] This utility model provides a positioning device for an aircraft trailing edge flap valve assembly, the structure of which is as follows: Figure 2 and Figure 3 As shown, the device includes a positioning mechanism 200 and an adjusting mechanism 300. The positioning mechanism 200 includes a positioning plate 210 and a first connecting member. The positioning plate 210 has a positioning port 211 for the front side of the valve body 110 of the valve assembly 100 to slide through. The first connecting member is detachably connected to the positioning plate 210 and the mounting plate 130 of the valve assembly 100. The adjusting mechanism 300 is detachably connected to the protruding end of the valve core 120 of the valve assembly 100 and is used to drive the valve core 120 to reciprocate along its axial direction to adjust the protruding length of the valve core 120.

[0025] When overhauling the valve assembly 100, the front side of the valve body 110 is slid through the positioning port 211, and the positioning plate 210 and the mounting plate 130 are detachably connected through the first connector, thereby positioning and fixing the valve assembly 100. Then, the adjusting mechanism 300 is detachably connected to the protruding end of the valve core 120, and hydraulic oil is injected into the valve body 110 through the external hydraulic oil circuit system to pressurize the valve body 110. The adjusting mechanism 300 drives the valve core 120 to reciprocate along its axial direction, thereby adjusting the protrusion length of the valve core 120. The pressure value inside the valve body 110 is measured by an external pressure testing system when the valve core 120 is at different protrusion lengths, so that the valve assembly 100 can be judged based on the pressure value. The trailing edge flap valve assembly positioning device of this aircraft is suitable for positioning the trailing edge flap valve assembly of this structure and can adjust the protrusion length of the valve core 120 in real time.

[0026] As a preferred embodiment, please refer to Figure 1 and Figure 2 The positioning plate 210 is also provided with a plurality of first connecting holes 212. There are a plurality of first connecting members. When the front side of the valve body 110 slides through the positioning port 211, each of the first connecting holes 212 corresponds one-to-one with each of the mounting holes 131 on the mounting plate 130. Each of the first connecting members slides one-to-one through each of the first connecting holes 212 and the corresponding mounting holes 131, and can detachably connect the positioning plate 210 and the mounting plate 130. When each of the first connecting holes 212 corresponds one-to-one with each of the mounting holes 131 on the mounting plate 130, each of the first connecting members slides one-to-one through each of the first connecting holes 212 and the corresponding mounting holes 131, and the positioning plate 210 and the mounting plate 130 are detachably connected, thereby positioning and fixing the valve assembly 100.

[0027] As a preferred embodiment, please refer to Figure 2The first connector includes a first stud and two first nuts. The first stud slides through the first connecting hole 212 and the corresponding mounting hole 131. The two first nuts are both sleeved on the first stud and threadedly connected to the first stud. The end faces of the two first nuts abut against the side wall of the positioning plate 210 and the side wall of the mounting plate 130, respectively. When each of the first connecting holes 212 corresponds one-to-one with each of the mounting holes 131 on the mounting plate 130, the first studs are slid through each of the first connecting holes 212 and the corresponding mounting holes 131, and the two first nuts are threadedly sleeved on the first studs. The two first nuts are rotated until the end faces of the two first nuts abut against the side wall of the positioning plate 210 and the side wall of the mounting plate 130, respectively, thereby positioning and fixing the valve assembly 100.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 The adjusting mechanism 300 includes a docking block 310, a second connecting member, and a driving member 320. The docking block 310 has an insertion hole 311 at one end near the positioning plate 210. The insertion hole 311 is coaxially arranged with the positioning port 211 and is used to allow the protruding end of the valve core 120 to slide into it. The second connecting member is detachably connected to the docking block 310 and the valve core 120. The driving member 320 is connected to the docking block 310 and is used to drive the docking block 310 to reciprocate along the axial direction of the valve core 120 to adjust the protruding length of the valve core 120. When the valve assembly 100 is under maintenance, the front side of the valve body 110 is slid through the positioning port 211, and the protruding end of the valve core 120 is slid into the insertion hole 311. After the positioning mechanism 200 positions and fixes the valve assembly 100, the docking block 310 and the valve core 120 are detachably connected through the second connecting member. The driving member 320 can drive the docking block 310 to reciprocate along the axial direction of the valve core 120, thereby driving the valve core 120 to reciprocate along its axial direction and realizing the adjustment of the protrusion length of the valve core 120.

[0029] As a preferred embodiment, please refer to Figure 2 and Figure 3The docking block 310 is provided with a second connecting hole 312 at one end near the positioning plate 210. The second connecting hole 312 extends radially along the insertion hole 311 and penetrates the insertion hole 311. When the protruding end of the valve core 120 is slidably inserted into the insertion hole 311, the second connecting hole 312 corresponds to the through hole 121 on the valve core 120. The second connector slides through the second connecting hole 312 and the through hole 121 and detachably connects the docking block 310 and the valve core 120. When the second connecting hole 312 corresponds to the through hole 121 on the valve core 120, the second connector slides through the second connecting hole 312 and the through hole 121 and detachably connects the docking block 310 and the valve core 120.

[0030] As a preferred embodiment, please refer to Figure 2 and Figure 3 The second connector includes a second stud and two second nuts. The second stud slides through the second connecting hole 312 and the through hole 121. The two second nuts are both sleeved on the second stud and threadedly connected to the second stud. The end faces of the two second nuts abut against the two opposite side walls of the mating block 310. When the second connecting hole 312 corresponds to the through hole 121 on the valve core 120, the second stud is slid through the second connecting hole 312 and the through hole 121, and the two second nuts are threadedly sleeved on the second stud. The two second nuts are rotated until the end faces of the two second nuts abut against the two opposite side walls of the mating block 310, thereby allowing the mating block 310 and the valve core 120 to be detachably connected.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4The adjusting mechanism 300 further includes a support plate 330, on which a screw hole 331 is formed. The screw hole 331 is coaxially arranged with the insertion hole 311. The driving component 320 includes a bushing 321, a shaft core 322, and a screw 323. The bushing 321 is coaxially arranged with the insertion hole 311 and is detachably fixed to the end of the mating block 310 away from the positioning plate 210 via screws. The shaft core 322 is rotatably disposed within the bushing 321. One end of the screw 323 rotatably extends into the bushing 321 and is connected to the shaft core 322. 2. Coaxial fixed connection: The other end of the screw 323 passes through the screw hole 331 and is threadedly connected to the screw hole 331. By rotating the screw 323 in the forward or reverse direction, since the screw 323 is threadedly connected to the screw hole 331 on the support plate 330, when the screw 323 rotates in the forward or reverse direction, the screw 323 will move along its axial direction, thereby driving the bushing 321 and the mating block 310 to perform reciprocating linear motion, and driving the valve core 120 to move reciprocally along its axial direction, thereby adjusting the extension length of the valve core 120.

[0032] As a preferred embodiment, please refer to Figure 4 The bushing 321 includes two semi-rings, which are detachably and fixedly connected by screws to form the bushing 321. When the two semi-rings are disassembled, it is convenient to install and remove the shaft core 322.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 The aircraft trailing edge flap valve assembly positioning device further includes a limiting mechanism 400, which is connected to the docking block 310 and is used to limit the rotation of the docking block 310 to prevent the valve core 120 from rotating around its own axis when it moves back and forth along its axial direction.

[0034] As a preferred embodiment, please refer to Figure 2 and Figure 3 The limiting mechanism 400 includes two limiting plates 410 and a limiting shaft 420. The two limiting plates 410 are disposed opposite to each other on both sides of the adjusting mechanism 300 and extend along the moving direction of the docking block 310. A limiting hole 313 is provided on the end of the docking block 310 away from the positioning plate 210. The limiting hole 313 extends radially along the insertion hole 311. The limiting shaft 420 slides through the limiting hole 313, and the two ends of the limiting shaft 420 are slidably connected to the two limiting plates 410 respectively. When the docking block 310 performs reciprocating linear motion, the docking block 310 is limited by the two limiting plates 410 due to its connection with the limiting shaft 420 and will not rotate. The valve core 120 will also not rotate.

[0035] As a preferred embodiment, please refer to Figure 2 and Figure 3 The limiting plate 410 has a first vertical section 411, a horizontal section 412, and a second vertical section 413 connected sequentially from bottom to top. The end of the limiting shaft 420 rests on the horizontal section 412 and slides against the side wall of the second vertical section 413. When the docking block 310 performs reciprocating linear motion, it will drive the limiting shaft 420 to perform reciprocating linear motion. Since the two ends of the limiting shaft 420 rest on the corresponding horizontal section 412 and slide against the side wall of the corresponding second vertical section 413, the limiting shaft 420 can be limited. The docking block 310 is limited by the two limiting plates 410 because it is connected to the limiting shaft 420, and will not rotate. The valve core 120 will also not rotate.

[0036] As a preferred embodiment, please refer to Figure 2 and Figure 3 The second vertical section 413 has a slot 4131 at the end away from the positioning plate 210. When assembling or disassembling the limiting shaft 420, the driving member 320 is operated to drive the docking block 310 to move away from the positioning plate 210 along the axial direction of the valve core 120 until the limiting hole 313 corresponds to the slot 4131. The limiting shaft 420 can be passed through the slot 4131 first and then through the limiting hole 313 to complete the installation of the limiting shaft 420. Alternatively, the limiting shaft 420 can be moved out of the limiting hole 313 first and then out of the slot 4131 to complete the disassembly of the limiting shaft 420.

[0037] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below:

[0038] When overhauling the valve assembly 100, the front side of the valve body 110 is slid through the positioning port 211, and the protruding end of the valve core 120 is slid into the insertion hole 311. At this time, each of the first connecting holes 212 corresponds one-to-one with each of the mounting holes 131 on the mounting plate 130, and the second connecting holes 312 correspond to the through holes 121 on the valve core 120. Each of the first studs is slid through the first connecting holes 212 and the corresponding mounting holes 131, and both first nuts are threaded onto the first studs. The two first nuts are rotated until the end faces of the two first nuts are respectively abutted against the side walls of the positioning plate 210 and the mounting plate 130, thereby positioning and fixing the valve assembly 100. The second studs are slid through the second connecting holes 312 and the through holes 121, and both second nuts are threaded onto the second studs. The two second nuts are rotated until the end faces of the two second nuts are respectively abutted against the side walls of the positioning plate 210 and the mounting plate 130. The two opposing sidewalls of the mating block 310 are pressed together, thereby detachably connecting the mating block 310 and the valve core 120. Hydraulic oil is injected into the valve body 110 through an external hydraulic oil circuit system, putting the valve body 110 into a pressurized state. By rotating the screw 323 in either the forward or reverse direction, since the screw 323 is threadedly connected to the screw hole 331 on the support plate 330, when the screw 323 rotates in either direction, it will move axially, thereby driving the bushing 321. The docking block 310 reciprocates linearly and drives the valve core 120 to reciprocate along its axial direction, thereby adjusting the extension length of the valve core 120. The pressure value inside the valve body 110 is measured by an external pressure testing system when the valve core 120 is at different extension lengths. The pressure value can be used to determine whether the valve assembly 100 meets the requirements. This aircraft trailing edge flap valve assembly positioning device is suitable for positioning the trailing edge flap valve assembly of this structure and can adjust the extension length of the valve core 120 in real time.

[0039] The aircraft trailing edge flap valve assembly positioning device provided by this utility model has the following beneficial effects:

[0040] (1) Slide the protruding end of the valve core 120 into the insertion hole 311. The second connecting hole 312 corresponds to the through hole 121 on the valve core 120. Slide the second stud through the second connecting hole 312 and the through hole 121. Thread the two second nuts onto the second stud. Rotate the two second nuts until the end faces of the two second nuts abut against the two opposite side walls of the docking block 310, thereby making the docking block 310 and the valve core 120 detachably connected.

[0041] (2) When the docking block 310 reciprocates linearly, it will drive the limiting shaft 420 to reciprocate linearly. Since the screw 323 is rotatably connected to the bushing 321 via the shaft core 322, and the two ends of the limiting shaft 420 are mounted on the corresponding horizontal section 412 and slide against the side wall of the corresponding second vertical section 413, the limiting shaft 420 can be limited. The docking block 310 will not rotate because it is connected to the limiting shaft 420 and is limited by the two limiting plates 410. The valve core 120 will also not rotate.

[0042] (3) The trailing edge flap valve assembly positioning device of this aircraft is suitable for positioning the trailing edge flap valve assembly of this structure and can adjust the extension length of the valve core 120 in real time.

[0043] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
