Description

Technical Field

[0001] This utility model belongs to the field of aircraft manufacturing technology, specifically a folding rudder working temperature testing device. Background Technology

[0002] With the rapid development of aerospace and other fields, folding rudders, as key components in aircraft control systems, are becoming increasingly widely used and important. Folding rudders can be folded and stored during aircraft launch and other phases to save space, and then unfolded to operate after entering a predetermined orbit, providing precise control for aircraft attitude adjustments and other operations. Different aircraft mission requirements have led to the development of various models of folding rudders, which differ significantly in size, shape, and structural details. This places higher demands on the versatility of folding rudder-related testing and supporting equipment to ensure efficient and accurate performance testing of different folding rudder models.

[0003] Folding rudders face complex and variable temperature environments in actual operation, such as the ultra-low temperature environment outside the atmosphere and the high temperature environment generated by friction with the air during high-speed flight. Therefore, operating temperature testing is crucial, as it determines whether the folding rudder can function stably and reliably under various conditions. However, most existing folding rudder temperature testing devices have relatively fixed structures, and the mechanisms used to fix the folding rudder are often designed for specific models, lacking flexibility and making it difficult to effectively fix different models of folding rudders. This results in frequent replacement or adjustment of the device during temperature testing, low adaptability, and seriously affects testing efficiency and cost control.

[0004] Patent application number CN202322276844.6 discloses a folding rudder temperature testing fixture. This device uses a fixed plate and a movable plate to clamp and fix the folding rudder to be tested. This fixing device uses two plates to clamp and fix the rudder handle of the folding rudder. This structure is only suitable for clamping non-cylindrical rudder handles, thus having a low adaptability problem. At the same time, this clamping device also has the problem of insufficient clamping stability. Utility Model Content

[0005] The purpose of this invention is to provide a folding rudder operating temperature testing device to solve the following technical problems mentioned in the background art:

[0006] Existing mechanisms for securing folding rudders lack flexibility and are difficult to effectively secure different models of folding rudders.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A folding rudder temperature testing device includes a test chamber, a heating mechanism, a cooling mechanism, and a fixing mechanism. The heating, cooling, and fixing mechanisms are all housed within the test chamber. The heating and cooling mechanisms simulate operating temperatures, while the fixing mechanism is used to mount the folding rudder. The fixing mechanism includes a fixing plate, a clamping plate, a hinge rod, a connecting rod, a fixing seat, a first adjusting screw, a backing plate, a positioning seat, and a second adjusting screw. Two clamping plates are symmetrically arranged on the fixing plate and hinged to it. The hinge rod is hinged to the clamping plate, and the connecting rod is movably connected to the hinge rod. The fixing seat is fixed to the fixing plate, and the first adjusting screw is rotatably connected to the connecting rod and threadedly connected to the fixing seat. The backing plate is movably connected to the fixing plate, and the positioning seat is fixed to the fixing plate. The second adjusting screw is rotatably connected to the backing plate and threadedly connected to the positioning seat. A positioning space is formed between the clamping plate and the backing plate.

[0009] Furthermore, the test chamber includes a test chamber body, a cover, and a hydraulic rod. The cover is hinged to the test chamber body, and the two ends of the hydraulic rod are hinged to the cover and the test chamber body, respectively.

[0010] Furthermore, a hinge joint is fixedly connected to the clamp plate, and a hinge ring is fixedly connected to one end of the hinge rod, with the hinge ring rotatably connected to the hinge joint.

[0011] Furthermore, a movable sleeve is fixedly connected to one end of the hinge rod, and the movable sleeve is movably connected to the outside of the connecting rod.

[0012] Furthermore, a limiting frame is fixedly attached to the fixed plate, and a limiting slider is movably connected within the limiting frame; a through hole is provided in the middle of the limiting slider, and a hinge rod movably passes through the through hole.

[0013] Furthermore, sliding grooves are provided on the upper and lower sides inside the limiting frame, and limiting protrusions are fixedly connected to the upper and lower sides of the limiting slider, with the limiting protrusions slidably connected in the sliding grooves.

[0014] Furthermore, limit baffles are fixed to both sides of the connecting rod.

[0015] Furthermore, a fixed head is fixedly connected to the middle of the connecting rod, and the first adjusting screw is rotatably connected to the fixed head.

[0016] Furthermore, a connecting plate is provided on one side of the abutment, and intermediate columns are fixed to both sides of the connecting plate, with the intermediate columns also fixed to the abutment.

[0017] Furthermore, the plywood and baseboard are provided with anti-slip textures, which are crisscrossing patterns.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The unique design of the fixing mechanism in this invention allows it to adapt to different models of folding rudders. By rotating the first adjusting screw to adjust the angle between the clamping plates, the opening and closing degree of the clamping plates can be flexibly changed according to the size of the rudder handle of different folding rudders. Then, the second adjusting screw drives the abutment plate to press against the rudder handle, further stabilizing the folding rudder. This achieves effective fixing of various models of folding rudders, improving the versatility and practicality of the device. At the same time, the two clamping plates and the abutment plate of this invention use three-point positioning to stabilize the position of the rudder handle, ensuring the stability of the clamping.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example:

[0026] A folding rudder temperature testing device includes a test chamber, a heating mechanism, a cooling mechanism, and a fixing mechanism 2. The heating mechanism, cooling mechanism, and fixing mechanism 2 are all installed inside the test chamber. The heating mechanism and cooling mechanism are used to simulate the working temperature, and the fixing mechanism 2 is used to install the folding rudder.

[0027] The heating mechanism can be implemented using electric heating wires, infrared heating tubes, etc., while the refrigeration mechanism can be implemented by forming a refrigeration cycle system with components such as a compressor, condenser, throttling device, and evaporator, or it can be implemented using semiconductor refrigeration. The fixing mechanism 2 includes a fixing plate 11, a clamping plate 16, a hinge rod 12, a connecting rod 7, a fixing seat 6, a first adjusting screw 5, a backing plate 15, a positioning seat 22, and a second adjusting screw 21; the two clamping plates 16 are symmetrically arranged on the fixing plate 11 and hinged to the fixing plate 11, the hinge rod 12 is hinged to the clamping plate 16, the connecting rod 7 is movably connected to the hinge rod 12, the fixing seat 6 is fixed to the fixing plate 11, the first adjusting screw 5 is rotatably connected to the connecting rod 7 and threadedly connected to the fixing seat 6; the backing plate 15 is movably connected to the fixing plate 11, the positioning seat 22 is fixed to the fixing plate 11, the second adjusting screw 21 is rotatably connected to the backing plate 15 and threadedly connected to the positioning seat 22, and a positioning space is formed between the clamping plate 16 and the backing plate 15.

[0028] Specifically, in use, rotating the first adjusting screw 5 moves the connecting rod 7, which in turn moves the hinge rod 12. The hinge rod 12 then rotates the clamping plates 16 on both sides, thereby adjusting the angle between the clamping plates 16. It should be noted that during the rotation of the clamping plates 16, the hinge rod 12 will move axially along the connecting rod 7. Therefore, the hinge rod 12 needs to be movably connected to the connecting rod 7 to prevent interference. Adjusting the angle of the clamping plates 16 allows for easy adaptation to different models of folding rudder handles. After adjusting the clamping plates 16, insert the rudder handle into the positioning space and rotate the second adjusting screw 21. The second adjusting screw 21 moves the abutment plate 15, which presses the rudder handle against the clamping plates 16, thus stabilizing the folding rudder and facilitating testing of different models of folding rudders.

[0029] In a preferred embodiment, the test chamber includes a test chamber body 1, a cover 3, and a hydraulic rod 4. The cover 3 is hinged to the test chamber body 1, and both ends of the hydraulic rod 4 are hinged to the cover 3 and the test chamber body 1, respectively. The hinged connection between the cover 3 and the test chamber body 1 facilitates opening and closing, making it easy to place or remove the folding rudder. The hydraulic rod 4 connects the cover 3 and the test chamber body 1, providing auxiliary support for the cover 3, making its opening and closing smoother and less strenuous, and stabilizing the cover 3 at a suitable angle, facilitating the placement or replacement of the folding rudder to be tested.

[0030] In a preferred embodiment, a hinge joint 14 is fixedly connected to the clamping plate 16, and a hinge ring 13 is fixedly connected to one end of the hinge rod 12. The hinge ring 13 is rotatably connected to the hinge joint 14. The design of the hinge ring 13 enables a reliable rotatable connection between the hinge rod 12 and the clamping plate 16. This allows the hinge rod 12 to smoothly rotate the clamping plate 16 with the hinge joint 14 as the fulcrum when the first adjusting screw 5 moves the connecting rod 7 and the hinge rod 12. This allows for flexible adjustment of the angle between the clamping plates 16, facilitating the adaptation of different models of folding rudder handles. This rotatable connection method is relatively stable and can maintain the stability of the structural connection during multiple adjustments of the clamping plate 16 angle and during folding rudder installation and testing.

[0031] In a preferred embodiment, a movable sleeve 8 is fixedly connected to one end of the hinge rod 12, and the movable sleeve 8 is movably connected to the outside of the connecting rod 7. This connection between the movable sleeve 8 and the connecting rod 7 ensures relative flexibility of movement while maintaining their correlation to a certain extent, ensuring that when the connecting rod 7 moves, the corresponding force and displacement can be transmitted to the hinge rod 12 through the movable sleeve 8, thereby driving the clamping plate 16 to rotate.

[0032] In a preferred embodiment, a limiting frame 18 is fixedly connected to the fixed plate 11, and a limiting slider 10 is movably connected within the limiting frame 18. A through hole is provided in the middle of the limiting slider 10, through which the hinge rod 12 movably passes. The cooperation between the limiting frame 18 and the limiting slider 10 can limit and guide the hinge rod 12. During the process of adjusting the angle of the clamping plate 16 by moving the connecting rod 7 and the hinge rod 12 through the adjusting screw, it is ensured that the hinge rod 12 moves along a predetermined direction that meets design requirements, making the entire adjustment action more precise and stable, avoiding unnecessary deviation of the hinge rod 12, and thus ensuring that the clamping plate 16 can rotate smoothly as expected.

[0033] In a preferred embodiment, sliding grooves 17 are provided on the upper and lower sides of the inner side of the limiting frame 18, and limiting protrusions are fixedly connected to the upper and lower sides of the limiting slider 10, with the limiting protrusions slidably connected within the sliding grooves 17. The sliding grooves 17 on the upper and lower sides of the inner side of the limiting frame 18 cooperate with the limiting protrusions fixed to the upper and lower sides of the limiting slider 10 to provide precise guidance for the limiting slider 10. When the hinge rod 12 moves with the adjustment action, the limiting slider 10 will move along the direction defined by the sliding groove 17, thereby ensuring that the movement trajectory of the hinge rod 12 is accurate and as expected, making the operation of the angle of the entire adjusting clamp 16 more precise and stable.

[0034] In a preferred embodiment, limiting plates 9 are fixedly attached to both sides of the connecting rod 7. During the adjustment of the included angle of the clamping plate 16, the hinge rod 12 will move to a certain extent in the axial direction of the connecting rod 7. The limiting plates 9 can limit the axial movement range of the hinge rod 12 on the connecting rod 7, thus preventing the hinge rod 12 from disengaging from the effective connection with the connecting rod 7 due to excessive movement.

[0035] In a preferred embodiment, a fixing head 19 is fixedly connected to the middle of the connecting rod 7, and the first adjusting screw 5 is rotatably connected to the fixing head 19. When the first adjusting screw 5 rotates, it needs to convert its rotational motion into linear motion of the connecting rod 7, thereby driving the hinge rod 12 and adjusting the angle of the clamping plate 16. The fixing head 19 provides a suitable connection point between the first adjusting screw 5 and the connecting rod 7, so that the force generated by the rotation of the first adjusting screw 5 can be effectively transmitted to the connecting rod 7, driving the connecting rod 7 to move linearly, and the hinge rods 12 on both sides are evenly stressed, making them less likely to jam due to tilting.

[0036] In a preferred embodiment, a connecting plate 20 is provided on one side of the abutment plate 15, and intermediate columns 23 are fixedly connected to both sides of the connecting plate 20. The intermediate columns 23 are also fixedly connected to the abutment plate 15. The intermediate columns 23 and the connecting plate 20 can disperse the local force on the abutment plate 15, thereby protecting the abutment plate 15.

[0037] In a preferred embodiment, the clamping plate 16 and the base plate are provided with anti-slip textures, which are crisscrossing patterns. After placing the folding rudder's handle between the clamping plate 16 and the base plate 15, it needs to be secured to ensure that the folding rudder does not shift during temperature testing. The crisscrossing anti-slip textures increase the coefficient of friction between the clamping plate 16, the base plate 15, and the surface of the folding rudder's handle.
