Description

Technical Field

[0003] During installation and use, first prepare special tools and testing equipment, and ensure the cleanliness of the installation location. Then, taking the wing flap mounting bracket as an example, first calibrate the reference surface using a laser alignment instrument, adjust the flatness error using stainless steel shims, and then pre-tighten the bolts to the torque in three steps in diagonal order. Next, apply thread locking adhesive and install locking plates to prevent loosening. Then, insert the hydraulic rod pin into the L-shaped slot. Before inserting the hydraulic rod pin into the L-shaped slot or hinge hole of the mounting bracket, use a lint-free cloth to apply aviation-grade lubricating oil evenly to the pin surface and the bushing inner hole of the mounting bracket. Finally, lock the cotter pin to install the hydraulic rod in the designated position.

[0004] In routine maintenance, lubrication of the rotating parts of the shaft and base usually relies on manual periodic addition of lubricating oil to avoid abnormal wear and excessive frictional resistance. However, this method not only increases maintenance costs and manpower input, but also easily leads to insufficient lubrication due to untimely or negligent manual operation, which in turn aggravates component wear and shortens the service life of the mechanism. Therefore, a hydraulic rod mechanism mounting base is proposed to solve the above problems. Utility Model Content

[0018] 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.

[0019] Reference Figure 1 , Figure 3 , Figure 6 This utility model provides an embodiment of a hydraulic rod mechanism mounting base, including a base 1. A rotating shaft 9 is rotatably connected through the inner surface of the base 1, allowing the rotating shaft 9 to rotate at a designated position inside the base 1. A cylinder 2 is fixedly connected through the outer surface of the rotating shaft 9, allowing the cylinder 2 to rotate around the rotating shaft 9, thereby realizing the swing function of the hydraulic rod at different angles. An oil groove 11 is provided on the top of the outer surface of the base 1 to store lubricating oil, providing a basis for subsequent lubrication of the rotating shaft 9 and the rotating part of the base 1, ensuring the smooth operation of the rotating parts. An arc-shaped semi-ring 10 is slidably connected to the inner surface of the oil groove 11. The sliding of the arc-shaped semi-ring 10 in the oil groove 11 can change the spatial volume of the oil groove 11, squeezing the lubricating oil inside the oil groove 11 along the oil seepage hole. An arc-shaped component 7 is elastically connected to the top of the outer surface of the base 1 by a spring 8. The elasticity of the spring 8 allows the arc-shaped component 7 to... After being subjected to force, the mechanism resets, ensuring its reciprocating motion capability and maintaining the continuity of the automatic lubrication function. The bottom of the outer surface of the arc-shaped component 7 is slidably connected to the top of the inner surface of the base 1, and the bottom of the outer surface of the arc-shaped component 7 is fixedly connected to the top of the outer surface of the arc-shaped semi-ring 10. This allows the arc-shaped component 7 to drive the arc-shaped semi-ring 10 to slide along the inside of the oil groove 11 outside the base 1. The outer surface of the rotating shaft 9 is rotatably connected to the traction disc 4, allowing the traction disc 4 to rotate along the outer surface of the rotating shaft 9 to adjust the trigger angle of the hydraulic rod. The outer surface of the traction disc 4 is fixedly connected to the extrusion frame 6, which rotates with the rotation of the traction disc 4. This allows the protrusion inside the extrusion frame 6 to contact and connect with the inner surface of the extrusion frame 6 and the top of the outer surface of the arc-shaped component 7. This contact connection method realizes the force transmission from the traction disc 4 to the arc-shaped component 7, enabling the entire lubrication triggering mechanism to be realized and ensuring the reliability of the automatic lubrication function.

[0020] Reference Figures 3-5The inner surface of the traction disc 4 is provided with a switching component 5. The switching component 5 serves two purposes: firstly, it allows the traction disc 4 to be fixed to the outer surface of the rotating shaft 9, so that the rotating shaft 9 can drive the traction disc 4 to rotate when it rotates; secondly, it allows the hydraulic rod to be adjusted to trigger the arc-shaped semi-ring 10 at different rotation angles. The switching component 5 includes a switching element 501, and a locking block 503 is fixedly connected to the rear of the outer surface of the switching element 501. The outer surface of the traction disc 4 has a slot 504, and the outer surface of the locking block 503 is inserted into the inner surface of the slot 504. The function of the locking block 503 is to cooperate with the slot 504 to realize the locking of the switching element 501 and the traction disc 4, ensuring that the rotation of the rotating shaft 9 can be reliably transmitted to the traction disc 4 after the switching angle is changed, thus ensuring the stability of the mechanism.

[0021] Reference Figure 3 , Figure 5 The switching component 5 also includes a bolt 502. The outer surface of the bolt 502 penetrates and is rotatably connected to the inner surface of the switching component 501, so that when the bolt 502 rotates, it can drive the switching component 501 to move laterally without driving the switching component 501 to rotate. This realizes the installation and disassembly function of the switching component 501 and provides an operating means for angle adjustment. The rear part of the outer surface of the bolt 502 is threadedly connected to the inner surface of the rotating shaft 9. The threaded connection has a self-locking characteristic, which can ensure that the bolt 502 will not loosen on its own during the operation of the mechanism, ensuring the fixed stability of the switching component 501 and the rotating shaft 9. The outer surface of the bolt 502 penetrates and is fixedly connected to a limit ring 505. The outer surface of the limit ring 505 is rotatably connected to the inner surface of the switching component 501, so that when the bolt 502 drives the limit ring 505 to rotate, it can drive the switching component 501 to move laterally without driving the switching component 501 to rotate.

[0022] Reference Figure 3 , Figure 6 The inner surface of the oil groove 11 is provided with oil seepage holes. Multiple sets of oil seepage holes are arranged in a ring on the inner surface of the oil groove 11. The multiple sets of ring-shaped oil seepage holes can make the lubricating oil evenly distributed on the rotating contact surface between the rotating shaft 9 and the base 1, which improves the lubrication effect, reduces wear, and extends the service life of the mechanism. One end of the spring 8 is fixedly connected to the bottom end of the outer surface of the arc-shaped part 7, and the other end of the spring 8 is fixedly connected to the top end of the outer surface of the base 1. This ensures that the spring 8 can effectively apply elastic force to the arc-shaped part 7, so that the arc-shaped part 7 can accurately reset after being subjected to force, thus ensuring the reciprocating motion performance of the mechanism.

[0023] Reference Figures 2-4The outer surface of the base 1 is provided with an oil injection hole 12, which provides a channel for replenishing lubricating oil into the oil tank 11, facilitating the maintenance and upkeep of the mechanism and ensuring a sufficient supply of lubricating oil. The inner surface of the cylinder 2 is slidably connected to a piston rod 3. This sliding connection method realizes the conversion of hydraulic energy and mechanical energy, enabling the hydraulic rod to perform telescopic movements and complete various work tasks.

[0024] Reference Figures 2-3 , Figure 6 A sealing ring 13 is fixedly connected to the top of the inner surface of the base 1. The bottom of the outer surface of the arc-shaped part 7 penetrates and slides through the inner surface of the sealing ring 13. The sealing ring 13 can prevent lubricating oil leakage, maintain the amount of lubricating oil in the oil groove 11, improve lubrication efficiency, and also avoid the pollution of the surrounding environment by lubricating oil. There are two sets of traction discs 4, which are symmetrically arranged on the left and right sides of the base 1. The two sets of symmetrically arranged traction discs 4 can make the mechanism evenly stressed and can simultaneously lubricate both sides of the rotating shaft 9.

[0025] Working principle: When the hydraulic rod is running, the rotating shaft 9 fixed at the bottom of the cylinder 2 will rotate along the inner surface of the base 1. When the rotating shaft 9 rotates, it will drive the traction disc 4 to rotate at the same time. When the traction disc 4 rotates, it will drive the pressing frame 6 at its top to press the top of the arc-shaped part 7. As the arc-shaped part 7 moves downward, it will drive the arc-shaped semi-ring 10 to slide along the oil groove 11 inside the base 1. The arc-shaped semi-ring 10 will squeeze the lubricating oil in the oil groove 11 from the oil seepage hole inside the oil groove 11, thus achieving the effect of automatic lubrication of the rotating shaft 9 and the rotating part of the base 1.

[0026] When the hydraulic rod needs to press the frame 6 at different angles to trigger the arc-shaped semi-ring 10 to move vertically, first use a tool to unscrew the bolt 502, so that the switching piece 501 is brought out of the traction disc 4, and the fixing of the switching piece 501 to the rotating shaft 9 is released. Then, after the hydraulic rod is rotated to the specified angle, the switching piece 501 is fixed to the rotating shaft 9 again by the bolt 502. When the switching piece 501 is fixed inside the traction disc 4 by the bolt 502, the locking block 503 at the rear of the switching piece 501 will engage with the locking groove 504 opened inside the traction disc 4, so that when the rotating shaft 9 rotates, it can simultaneously drive the traction disc 4 to rotate. Thus, the arc-shaped semi-ring 10 can be triggered to move vertically by pressing the frame 6 at different angles through the switching piece 501, the locking block 503 and the locking groove 504.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
