Description

Technical Field

[0001] This utility model belongs to the field of positioning frame technology, and relates to an aircraft air intake rubber strip positioning frame with a rib positioning mechanism. Background Technology

[0002] Aircraft air intakes supply the air needed for the aircraft's engines to operate, directly affecting engine efficiency. They play a crucial role in engine proper functioning and thrust, thus significantly impacting aircraft performance, especially fighter jets. Currently, commonly used aircraft air intakes primarily come in two structural forms: sheet metal composite structures and integral composite material structures. Because air passes through the inner surface of the air intake, extremely high requirements are placed on the smoothness and shape precision of the inner surfaces of the components.

[0003] Aircraft air intakes require special brackets during transportation and maintenance. Existing brackets generally use fixed connections, but due to the significant differences in size between different models of air intakes, the brackets cannot meet the needs of other models of air intakes. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing an aircraft air intake rubber strip positioning bracket with a rib positioning mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning bracket for an aircraft air intake duct rubber strip with a rib positioning mechanism includes a carrier support and a fixed frame. The fixed frame is movably mounted on the carrier support. The carrier support includes a bottom fixed frame, a left support frame, a right support frame, and a drive bracket. The left support frame, right support frame, and drive bracket are all fixedly mounted on the bottom fixed frame. The top of the left support frame and right support frame are each provided with a bearing seat. Both ends of the fixed frame are movably mounted on the bearing seats. The top of the drive bracket is equipped with a drive mechanism. The output end of the drive mechanism is connected to a bushing. One side of the bushing is drivenly connected to the fixed frame. The rib positioning mechanism and the aircraft air intake are installed inside the fixed frame. The aircraft air intake is fixedly installed inside the fixed frame by the rib positioning mechanism.

[0009] In the aforementioned aircraft air intake duct rubber strip positioning bracket with rib positioning mechanism, the rib positioning mechanism includes a top fixed bracket, a bottom fixed bracket, and a side fixed bracket, both ends of which are fixedly connected to the connecting seat.

[0010] In the aforementioned aircraft air intake duct rubber strip positioning bracket with rib positioning mechanism, the top fixing bracket and the bottom fixing bracket are located at the upper and lower ends of the aircraft air intake, respectively, and the side fixing brackets are located on both sides of the aircraft air intake.

[0011] In the aforementioned aircraft air intake duct rubber strip positioning frame with rib positioning mechanism, an adjusting rod is fixedly installed on the top fixed bracket, the bottom fixed bracket, and the side fixed bracket. A connecting block is movably installed at one end of the adjusting rod, and an arc-shaped rubber strip is fixedly installed at one end of the connecting block by bolts. The arc-shaped rubber strip is tightly fitted to the outer wall of the aircraft air intake.

[0012] In the aforementioned aircraft air intake rubber strip positioning bracket with rib positioning mechanism, the driving mechanism includes a rotating handwheel and a gearbox. The gearbox is fixedly installed on the top of the driving bracket. One end of the rotating handwheel is connected to a gear inside the gearbox, and the output end of the gearbox is fixedly connected to a bushing.

[0013] In the aforementioned aircraft air intake rubber strip positioning frame with rib positioning mechanism, a rotating groove is provided on the bearing seat, a bearing is installed on the lower inner wall of the rotating groove, and the rotating main shaft is located above the bearing.

[0014] In the aforementioned aircraft air intake rubber strip positioning frame with rib positioning mechanism, a fixing plate is installed on the support seat, and the two ends of the fixing plate are connected to the support seat by screws. The top of the rotating spindle is installed in the rotating groove through the fixing plate.

[0015] In the aforementioned aircraft air intake rubber strip positioning bracket with rib positioning mechanism, the bushing is connected to the rotating main shaft via a spline shaft.
