Description

Technical Field

[0001] This utility model belongs to the field of aviation manufacturing technology, specifically an automatic lifting device for aviation composite panels. Background Technology

[0002] Aerospace composite panels are widely used due to their lightweight and high strength. However, during the processing, transportation, and assembly of aerospace composite panels, the height of the panels needs to be adjusted frequently. Traditional lifting devices often use mechanical clamps to fix the panels, which can easily cause pinching or scratches on the smooth and fragile aerospace composite panels, affecting the quality of the panels. In addition, there is a lack of effective cushioning and shock absorption measures during the lifting process. When the device starts, stops, or encounters external impacts, the panels are prone to shaking or even falling off, which not only affects the processing accuracy but also poses safety hazards.

[0003] Therefore, an automatic lifting device for aerospace composite panels is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an automatic lifting device for aerospace composite panels, solving the problems of easy damage to the panels during fixing and unstable lifting in existing devices, and realizing safe and stable automatic lifting of aerospace composite panels.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic lifting device for aerospace composite panels, comprising a base, wherein a lifting assembly is provided on the surface of the base, and a fixing assembly is installed on the upper side of the lifting assembly;

[0006] The fixing assembly includes a lifting platform disposed above the base. A U-shaped mounting plate is symmetrically fixedly connected to the surface of the lifting platform. A Z-shaped movable plate is slidably connected inside the mounting plate. A connecting rod is fixedly connected between the two sets of movable plates. A negative pressure suction cup is fixedly connected to the upper side of the movable plate. A vacuum pump is fixedly installed on the side of the movable plate, and the output end of the vacuum pump is connected to the negative pressure suction cup through a connecting pipe.

[0007] Preferably, a pressure sensor is installed inside the negative pressure suction cup.

[0008] Preferably, a rubber anti-slip pad is fixedly connected to the upper surface of the movable plate.

[0009] Preferably, the mounting plate has several sets of sliding rods fixedly connected inside, and the movable plate is slidably sleeved on the surface of the sliding rods. The bottom surface of the movable plate is provided with a damping spring, and the damping spring is sleeved on the surface of the sliding rods.

[0010] Preferably, the lifting assembly includes fixed seats symmetrically fixedly connected to the base and the side adjacent to the lifting platform. A folding frame is symmetrically hinged between the two sets of fixed seats. A moving rod is provided between the fixed seats on adjacent sides, and the two ends of the moving rod are respectively hinged to the folding frame. A motor is installed on the upper surface of the base. The motor is connected to a bidirectional lead screw through a reducer, and the two sets of moving rods located on the lower side are symmetrically screwed onto the surface of the bidirectional lead screw.

[0011] Preferably, rollers are symmetrically rotatably connected to both sides of the movable rod, and the fixed base has a track groove inside for the rollers to roll.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a lifting component and starting the motor, can drive the moving rod to move horizontally through the bidirectional lead screw, so that the folding frame can be folded or unfolded, thereby realizing the lifting operation of the lifting platform. In addition, the folding frame, together with the rollers, reduces the frictional resistance during the lifting process, making the lifting platform run more smoothly and stably.

[0014] 2. By setting up a fixed component, a vacuum pump generates negative pressure in the suction cup, and a pressure sensor monitors the pressure inside the suction cup in real time, ensuring that the board is firmly adsorbed. The operation is simple and convenient, achieving fast and accurate positioning of the board without causing any damage to the surface of the board, thus ensuring the quality of the aerospace composite board. When the lifting platform starts, stops, or is subjected to external impact, the damping spring can absorb and dissipate the impact force, ensuring the stability of the board, while reducing mechanical wear during equipment operation and improving the service life of the device.

Detailed Implementation

[0020] 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.

[0021] like Figures 1 to 4 As shown, this utility model provides an automatic lifting device for aviation composite panels, including a base 1, a lifting component 2 disposed on the surface of the base 1, and a fixing component 3 installed on the upper side of the lifting component 2.

[0022] The fixing component 3 includes a lifting platform 31 set above the base 1. A U-shaped mounting plate 32 is symmetrically fixedly connected to the surface of the lifting platform 31. A Z-shaped movable plate 33 is slidably connected inside the mounting plate 32. A connecting rod 34 is fixedly connected between the two movable plates 33. A negative pressure suction cup 35 is fixedly connected to the upper side of the movable plate 33. A vacuum pump 36 is fixedly installed on the side of the movable plate 33, and the output end of the vacuum pump 36 is connected to the negative pressure suction cup 35 through a connecting pipe 37. When fixing the aerospace composite material, the surface of the material is cleaned and placed above the lifting platform 31. Then, the vacuum pump 36 is started, and the vacuum pump 36 delivers negative pressure to the negative pressure suction cup 35 through the connecting pipe 37. The pressure inside the negative pressure suction cup 35 drops rapidly. Under atmospheric pressure, the aerospace composite material placed on the movable plate 33 is tightly adsorbed and positioned. By releasing the negative pressure of the negative pressure suction cup 35, the material can be separated, improving the convenience of positioning the material. Furthermore, the adsorption method is less likely to damage the surface of the material.

[0023] The negative pressure suction cup 35 is equipped with a pressure sensor. The pressure sensor monitors the pressure value inside the negative pressure suction cup 35 in real time, thereby accurately controlling the adsorption force on the board. When the pressure is lower than the preset value, the control system automatically issues an alarm and strengthens the adsorption force to ensure that the board is firmly fixed and to prevent it from falling off during the lifting process.

[0024] The upper surface of the movable plate 33 is fixedly connected with a rubber anti-slip pad, which can improve the fixing effect of the plate and reduce the vibration and friction between the plate and the movable plate 33.

[0025] like Figures 1 to 4 As shown, several sets of slide rods 38 are fixedly connected inside the mounting plate 32, and the moving plate 33 is slidably sleeved on the surface of the slide rods 38. A damping spring 39 is provided on the bottom surface of the moving plate 33, and the damping spring 39 is sleeved on the surface of the slide rods 38. When the lifting platform 31 vibrates, the moving plate 33 will slide on the surface of the slide rods 38 and compress the damping spring 39 to generate deformation, converting the vibration impact force into the elastic force of the damping spring 39, thereby achieving buffering and absorption of the vibration of the lifting platform 31, reducing the shaking of the lifting platform 31, and ensuring the stability of the aviation composite material.

[0026] like Figures 1 to 4 As shown, the lifting assembly 2 includes fixed seats 21 symmetrically fixedly connected to the base 1 and the adjacent side of the lifting platform 31. A folding frame 22 is symmetrically hinged between the two sets of fixed seats 21. A moving rod 24 is provided between the adjacent fixed seats 21, and the two ends of the moving rod 24 are respectively hinged to the folding frame 22. A motor 26 is installed on the upper surface of the base 1. The motor 26 is connected to a bidirectional lead screw 27 through a reducer 25. The two sets of moving rods 24 located on the lower side are symmetrically screwed to the surface of the bidirectional lead screw 27. When the lifting platform 31 is adjusted for lifting, the motor 26 is started, and the bidirectional lead screw 27 is driven to rotate through the reducer 25. This drives the moving rod 24, which cooperates with the bidirectional lead screw 27, to move horizontally between the fixed seats 21. The horizontal displacement of the moving rod 24 causes the folding frame 22 to retract or unfold. Since the two ends of the folding frame 22 are respectively connected to the base 1 and the lifting platform 31, the vertical lifting movement of the lifting platform 31 is realized.

[0027] The movable rod 24 is symmetrically connected to rollers 23 on both sides, and the fixed base 21 has a track groove for the rollers 23 to roll inside. When the movable rod 24 moves, it will drive the rollers 23 to roll inside the fixed base 21, reducing the frictional resistance when the folding frame 22 moves, making the lifting process more stable and smooth.

[0028] Working principle and process: When fixing the aviation composite material, the surface of the material is cleaned and placed above the lifting platform 31. Then, the vacuum pump 36 is started. The vacuum pump 36 delivers negative pressure to the negative pressure suction cup 35 through the connecting pipe 37. The pressure inside the negative pressure suction cup 35 drops rapidly. Under the action of atmospheric pressure, the aviation composite material placed on the moving plate 33 is tightly adsorbed and positioned. When it is necessary to lift the lifting platform 31, the motor 26 is started. The reducer 25 drives the bidirectional lead screw 27 to rotate, and drives the moving rod 24, which cooperates with the bidirectional lead screw 27, to move horizontally between the fixed bases 21. The horizontal displacement of the moving rod 24 causes the folding frame 22 to retract or unfold. Since the two ends of the folding frame 22 are connected to the base 1 and the lifting platform 31 respectively, the vertical lifting movement of the lifting platform 31 is realized.
