[0046] like Figures 1 to 18As shown: This embodiment provides an adjustment device 100 for the diaphragm of an actuating cylinder in an aircraft valve component. It relates to pneumatic valve components in aircraft air conditioning systems, bleed air systems, APU systems, and engine systems. Designed and manufactured based on the principles of simplicity, ease of use, and meeting maintenance needs, it includes a base plate 1, a bottom block 2, a middle block 3, a top block 5, and a sliding groove block 4. The base plate 1 and bottom block 2 are rotatably connected. The horizontal relative positions of the middle block 3 and bottom block 2 can be adjusted by a horizontal adjustment structure. The vertical relative positions of the middle block 3 and top block 5 are... The position can be adjusted by the vertical adjustment structure. The horizontal relative position of the top block 5 and the sliding groove block 4 can be adjusted. One end of the connecting rod of the actuator diaphragm 200 is used to connect with the bottom block 2. The sliding groove block 4 is provided with a shaft pin 12. The shaft pin 12 passes through the ball head of the fisheye connector at the other end of the connecting rod of the actuator diaphragm 200 to simulate the assembly effect of the connecting rod of the actuator diaphragm 200 for subsequent installation and maintenance work. The top block 5 is provided with a positioning pin 10. The positioning pin 10 is used to pass through the diaphragm hole of the actuator diaphragm 200.

[0047] Specifically, in this embodiment, a bearing seat 22 is provided on the base plate 1. The bearing seat 22 is used to connect to one end of the connecting rod of the actuating cylinder diaphragm 200. The bearing seat 22 and the base block 2 are rotatably connected by a bearing 23 to reduce the friction between the base block 2 and the base, so that the base block 2 can rotate freely 360 degrees during use, which facilitates the maintenance operation of maintenance engineers.

[0048] In this embodiment, the horizontal adjustment structure includes a horizontal adjustment screw 6 and a first handle 7. The horizontal adjustment screw 6 can extend into the bottom block 2 and is threadedly connected to the bottom block 2. The horizontal adjustment screw 6 is rotatably connected to the middle block 3 through a bearing 23. The outer end of the horizontal adjustment screw 6 is provided with a first handle 7, which is located outside the middle block 3. By adjusting the first handle 7, the horizontal adjustment screw 6 rotates, so that the bottom block 2 and the base plate 1 move horizontally at the same time.

The bottom block 2 has a first indicator line 16 near the end of the second middle block portion 26, and a first horizontal scale line 17 is provided on the first middle block portion 25. By aligning the first indicator line 16 with the first horizontal scale line 17, the horizontal displacement can be accurately read. According to the size of the actuating cylinder diaphragm 200 to be adjusted, the final horizontal position of the device is determined. After the horizontal adjustment screw 6 is adjusted, the relative position of the bottom block 2 and the first middle block portion 25 is fixed by the first fixing structure 13. The first fixing structure 13 is preferably a set screw.

[0050] In this embodiment, the top block 5 includes a first top block portion 27 and a second top block portion 28. The second top block portion 28 is arranged perpendicularly to the first top block portion 27. The first top block portion 27 has second sliding grooves 29 on both sides. The second middle block portion 26 and the first top block portion 27 can slide relative to each other in the vertical direction. The second top block portion 28 has a plurality of through holes 15 for placing positioning pins 10 along the length direction of the second top block portion 28.

The vertical adjustment screw rotates relative to the middle block 3. The lower end of the vertical adjustment screw 8 is provided with the second handle 9. By adjusting the second handle 9, the vertical adjustment screw 8 rotates, causing the top block 5 to move vertically relative to the middle block 3.

[0052] In this embodiment, a second indicator line 18 is provided at one end of the first top block 27 near the first middle block 25, and a vertical scale line 19 is provided on the second middle block 26. By aligning the second indicator line 18 with the second horizontal scale line 21, the displacement of the top block 5 in the vertical direction can be accurately read. Based on the required dimensions of the actuator diaphragm 200 connecting rod to be adjusted, the final installation dimensions on the actuator diaphragm 200 connecting rod are determined.

[0053] In this embodiment, the sliding block 4 includes a first sliding block portion 31 and a second sliding block portion 32. The second top block portion 28 is provided with third sliding grooves 30 on both sides.

The end of the first sliding block portion 31 away from the first top block portion 27 is provided with a third indicator line 20. The second top block portion 28 is provided with a second horizontal scale line 21. By aligning the third indicator line 20 with the second horizontal scale line 21, the displacement dimension of the sliding block 4 in the horizontal direction can be indicated. The displacement amount in the horizontal direction can be accurately read. According to the size of the actuating cylinder diaphragm 200 to be adjusted, the final horizontal dimension of the device is determined. After the adjustment is completed, the relative position of the first sliding block portion 31 and the second top block portion 28 is fixed by the second fixing structure 14. The second fixing structure 14 is preferably a set screw.

The stop block 11 includes a connecting part 33 and a limiting part 34. The connecting part 33 is detachably connected to the second sliding groove block part 32 of the sliding groove block 4. After the diaphragm is installed, the limiting part 34 is located in the placement groove and is used to limit the ball head of the fisheye connector to ensure that it cannot deflect and to carry out subsequent installation and maintenance work.

[0055] like Figure 19 As shown, an adjustment device 100 for the diaphragm of an actuating cylinder of an aircraft valve component is installed. The diaphragm is installed on the adjustment device 100 and adjusted to the height stroke required by the manufacturer. Then, the set screw is tightened, and the scale values ​​in each direction are recorded. In this embodiment, a shaft pin 12 is connected to the fisheye connector of the actuating cylinder diaphragm 200. A positioning pin 10 passes through the diaphragm hole of the actuating cylinder diaphragm 200 and simultaneously engages with the shaft seat 22 on the base plate 1 to achieve length positioning. Finally, a special wrench is used to tighten and fix the actuating cylinder diaphragm 200, thereby completing the adjustment and assembly process of the actuating cylinder diaphragm 200.

[0056] This embodiment solves the problem of difficulty in adjusting the size of the actuator diaphragm 200 connecting rod and the inability to quickly adjust and fix it.

[0057] The horizontal and vertical positions of the actuator diaphragm 200 can be adjusted using this embodiment, and the actual displacement dimension can be indicated. It can also be rotated 360 degrees through the base plate 1, and can accommodate actuator diaphragms 200 of different specifications, so as to meet the maintenance requirements of valve components.

[0058] This embodiment consists of multiple modular parts. During use, different adjustment and positioning functions can be achieved by replacing each modular component. It has strong expandability to meet the adjustment and installation requirements of various types and specifications of actuator diaphragm 200, thus satisfying maintenance needs.

[0059] This embodiment is compact and lightweight, enabling multi-site maintenance and avoiding maintenance requirements where work cannot be transferred.

[0060] This embodiment can linearly and smoothly achieve the required dimensions of the diaphragm actuator in all directions, and the extension and retraction movements are smooth and free. When extending and retracting, it effectively avoids jamming during maintenance and use, and meets the maintenance requirements in terms of accuracy.

[0061] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention.
