Description

Technical Field

[0001] This utility model relates to the field of aviation product maintenance technology, and more specifically to an aircraft cockpit canopy control actuator angle installation device for angle installation of aircraft cockpit canopy control actuators. Background Technology

[0002] The canopy control actuator consists of a hydraulic chamber, a pneumatic chamber, and a resilient locking mechanism. It is an accessory to the aircraft canopy pneumatic system, used to operate the canopy's opening, closing, or any stroke. The main structure is a pneumatic-hydraulic series actuator. Under normal circumstances, the pneumatic part is driven by compressed nitrogen. When the pneumatic system is depressurized, it can also be operated manually (hydraulically). In an emergency, the lower pneumatic chamber is filled with high-pressure gas to jettison the canopy.

[0003] During assembly, the joints on the canopy control actuators must be at specific angles to ensure correct installation on the machine and prevent interference with other machine structures. Current installation methods, relying on visual comparison with the original or finished product to determine the angle of each joint, result in significant errors and cannot guarantee the stability and accuracy of the installation angle. Furthermore, the actuator lacks stable and reliable fixing points during installation, and adjusting the product position relies on manual lifting and rotation, which is inconvenient. Additionally, the installation angles differ between single-seat and two-seat models, posing a risk of confusion and incorrect installation.

[0004] Therefore, it is necessary to design a device that can reliably complete the angle installation of the aircraft cockpit canopy control actuator, improve installation efficiency, ensure accurate joint installation angle, reduce installation errors, improve installation safety, and be able to complete the angle installation of multiple aircraft models. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] See appendix Figure 1 To be continued Figure 2 This utility model embodiment discloses an aircraft cockpit canopy control actuator angle mounting device, including: a work platform vehicle 1;

[0041] The work platform 12 of the work platform vehicle 1 is equipped with a double-seat angle installation module 2 and a single-seat angle installation module 3, which are respectively located on both sides of the work platform 12.

[0042] Both the dual-seat angle mounting module 2 and the single-seat angle mounting module 3 include a bracket fixed on the working platform 12. The bracket is used to support the cockpit canopy control actuator to be installed. Both the dual-seat angle mounting module 2 and the single-seat angle mounting module 3 also include a locking pin positioning component installed on the working platform 12. The locking pin positioning component is arranged on the outside of the bracket and is connected and positioned with the connector on the cockpit canopy control actuator.

[0043] See appendix Figure 3 The work platform vehicle 1 is assembled from the vehicle body 11, the work platform 12, and the support legs 13.

[0044] The vehicle body 11 is assembled from a system of struts, longitudinal bars, uprights, and transverse bars. It employs a reinforced structure and four-point positioning fastening, ensuring the rigidity of the vehicle body 11 allows it to withstand heavy loads without deformation, guaranteeing installation stability and accuracy. The bottom of the vehicle body 11 is equipped with two flat-topped iron-core PU full-brake wheels 14 and two flat-topped iron-core PU directional wheels 15 for flexible movement. Pulling the handle 16 moves the cockpit canopy control actuator angle mounting device, allowing the work location to be changed as needed. The work platform 12 is mounted on the vehicle body 11 and is used to mount the components of the double-seat angle mounting module 2 and the components of the single-seat angle mounting module 3.

[0045] The bottom of the vehicle body 11 is equipped with four support legs 13. Adjusting the support legs 13 can adjust the height of the work platform 12 off the ground to suit the working habits of different operators, and also to fix the vehicle body 11 during installation to prevent it from moving. The bottom of the support legs 13 is fixed with spring washers and flat washers by hexagonal head bolts, which increases the support area, reduces vibration and stabilizes the vehicle body, and reduces the impact of shaking during assembly.

[0046] See appendix Figure 4The dual-seat angle mounting module 2 is equipped with dual-seat model frame one 21, dual-seat model frame two 23, and dual-seat model frame three 25, as well as dual-seat machine bracket one 22 and dual-seat machine bracket two 24. Dual-seat machine bracket one 22 and dual-seat machine bracket two 24 are fastened to the work platform 12 with hexagonal head screws, which can stably support the actuator cylinder without deformation. The brackets are equipped with rubber pads to prevent scratches and bumps to the actuator cylinder. The bracket grooves are semi-circular to fit the outer diameter of the actuator cylinder, improving stability and preventing rolling.

[0047] See appendix Figure 5 The double-seat frame 21 has a waist-shaped groove on its upper part. The displacement of the double-seat pin 212 within this groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the double-seat pin 212 is locked in the horizontal direction. The other end of the double-seat pin 212, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the double-seat process connector 213. Thus, the installation angle of the canopy operating actuator is locked in the horizontal direction by the double-seat pin 212. The waist-shaped groove has a size of Φ60 (0~0.03), and the diameter of the part of the double-seat pin 212 within the waist-shaped groove is Φ60 (-0.01~-0.05), resulting in a very small fit clearance, which can precisely limit the angle requirements during assembly. The double-seat pin 212 is connected to the double-seat frame 21 via a double-seat steel cable 211, facilitating use and preventing loss. The double-seat frame 21 is fastened to the work platform 12 by double-seat hexagonal thin nuts 214. The reinforced structure is stable, reliable and does not deform.

[0048] See appendix Figure 6 The double-seat frame 23 has a waist-shaped groove above it. The displacement of the double-seat pin 232 within this groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the double-seat pin 232 is locked at 50° to the horizontal. The other end of the double-seat pin 232, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the double-seat process connector 233. Thus, the installation angle of the canopy operating actuator is locked at 50° to the horizontal by the double-seat pin 232. The waist-shaped groove has a dimension of Φ60 (0~0.03), and the diameter of the part of the double-seat pin 232 within the waist-shaped groove is Φ60 (-0.01~-0.05), resulting in a very small clearance and precise control over the angle requirements during assembly. The double-seat pin 232 is connected to the double-seat frame 23 via a double-seat steel cable 231, facilitating use and preventing loss. The double-seat frame 23 is fastened to the work platform 12 by double-seat hexagonal thin nuts 234. The reinforced structure is stable, reliable and does not deform.

[0049] See appendix Figure 7The double-seat frame 325 has a waist-shaped groove above it. The displacement of the double-seat pin 3252 within this groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the double-seat pin 3252 is locked at 45° to the horizontal. The other end of the double-seat pin 3252, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the double-seat process connector 3253. Thus, the installation angle of the canopy operating actuator is locked at 45° to the horizontal by the double-seat pin 3252. The waist-shaped groove has a dimension of Φ60 (0~0.03), and the diameter of the part of the double-seat pin 3252 within the waist-shaped groove is Φ60 (-0.01~-0.05), resulting in a very small clearance and precise control over the angle requirements during assembly. The double-seat pin 3252 is connected to the double-seat frame 325 via a double-seat steel cable 3251, facilitating use and preventing loss. The double-seat frame 325 is fastened to the work platform 12 by double-seat hexagonal thin nuts 3254. The reinforced structure is stable, reliable and does not deform.

[0050] See appendix Figure 8 The single-seat angle mounting module 3 is equipped with single-seat model frame one 31, single-seat model frame two 33, and single-seat model frame three 35, as well as single-seat bracket one 32 and single-seat bracket two 34. Single-seat bracket one 32 and single-seat bracket two 34 are fastened to the work platform 12 with hexagonal head screws, which can stably support the actuator cylinder without deformation. The brackets are equipped with rubber pads to prevent scratches and bumps to the actuator cylinder. The bracket grooves are semi-circular to fit the outer diameter of the actuator cylinder, improving stability and preventing rolling.

[0051] See appendix Figure 9 The single-seat frame 31 has a waist-shaped groove on its upper part. The displacement of the single-seat pin 312 in the waist-shaped groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the single-seat pin 312 is locked in the horizontal direction. The other end of the single-seat pin 312, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the single-seat process connector 313. Therefore, the installation angle of the canopy operating actuator is locked in the horizontal direction by the single-seat pin 312. The size of the waist-shaped groove is Φ60 (0~0.03), and the diameter of the part of the single-seat pin 312 in the waist-shaped groove is Φ60 (-0.01~-0.05). The fit clearance is very small, which can precisely limit the angle requirements during assembly. The single-seat pin 312 is connected to the single-seat frame 31 via a single-seat steel cable, which is convenient to use and prevents loss. The single-seat frame 31 is fastened to the work platform 12 by a single-seat hexagonal thin nut 314. The reinforced structure is stable, reliable and does not deform.

[0052] See appendix Figure 10The single-seat frame 233 has a waist-shaped groove above it. The displacement of the single-seat pin 232 within this groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the single-seat pin 232 is locked in the horizontal direction. The other end of the single-seat pin 232, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the single-seat process connector 233. Thus, the installation angle of the canopy operating actuator is locked in the horizontal direction by the single-seat pin 232. The waist-shaped groove has a size of Φ60 (0~0.03), and the diameter of the part of the single-seat pin 232 within the waist-shaped groove is Φ60 (-0.01~-0.05), resulting in a very small clearance and precise control over the angle requirements during assembly. The single-seat pin 232 is connected to the single-seat frame 233 via a single-seat steel cable 231, facilitating use and preventing loss. The single-seat frame 233 is fastened to the work platform 12 by a single-seat hexagonal thin nut 2334. The reinforced structure is stable, reliable and does not deform.

[0053] See appendix Figure 11 The single-seat frame 35 has a waist-shaped groove above it. The displacement of the single-seat pin 352 within this groove is restricted to the horizontal direction and the direction perpendicular to the groove. Therefore, the angle of the single-seat pin 352 is locked at 38° with the horizontal direction. The other end of the single-seat pin 352, passing through the waist-shaped groove, is connected to the canopy operating actuator along with the single-seat process connector 353. Thus, the installation angle of the canopy operating actuator is locked at 38° with the horizontal direction by the single-seat pin 352. The waist-shaped groove has a dimension of Φ60 (0~0.03), and the diameter of the part of the single-seat pin 352 within the waist-shaped groove is Φ60 (-0.01~-0.05), resulting in a very small clearance and precise control over the angle requirements during assembly. The single-seat pin 352 is connected to the single-seat frame 35 via a single-seat steel cable 351, facilitating use and preventing loss. The single-seat frame 335 is fastened to the work platform 12 by a single-seat hexagonal thin nut 3354. The reinforced structure is stable, reliable and does not deform.

[0054] The usage method of this embodiment is as follows:
