[0001] This utility model relates to the field of aircraft seat back assembly assistance, specifically a high-precision assembly assistance device for aircraft seat backs. Background Technology

[0002] The aircraft seat back assembly auxiliary device is a machine that assists in assembling the aircraft seat back to the frame. Its core advantages are labor-saving efficiency, precise positioning, and suitability for symmetrical aircraft seat assembly. The core components include a support base and casters, ensuring both stable support and flexible movement. Some units are equipped with counterweights and vacuum suction cups to enhance anti-tilt stability. The adjustment mechanism includes vertical and horizontal guide rails, allowing adjustment of assembly height and horizontal position to accommodate different assembly points. The fixing components include fixed grippers and a control panel, which securely hold the seat back and prevent assembly misalignment. The drive and control system includes cylinders, hydraulic cylinders, and a control panel, allowing one-button operation of lifting, lowering, and horizontal movement, eliminating the need for manual handling and adjustment.

[0003] For example, publication number CN203245566U discloses an aircraft seat backrest assembly auxiliary device, including a support base and a backrest assembly device mounted on the support base. The backrest assembly device includes a fixing plate, a lifting plate, a backrest fixing assembly, and a driving device. The aircraft seat backrest assembly auxiliary device of this utility model can simultaneously adjust the horizontal position and height according to the installation position of the backrest. The installer only needs to stand at a fixed point and place the backrest onto the control panel of the auxiliary device. The auxiliary device can then easily and simply install the backrest onto the frame.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, it was found that: although existing assembly auxiliary devices can conveniently assemble backrests, they still lack a certain degree of precision. When assembling different models of seats, they cannot accurately match the positions. At the same time, the assembly auxiliary devices do not have a moving mechanism, making it difficult to move them when not in use. In view of this, the inventors urgently need to design a high-precision assembly auxiliary device for aircraft seat backrests to solve the technical problems of insufficient assembly accuracy and inflexible movement. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-precision assembly auxiliary device for aircraft seat backs to solve the technical problems of insufficient assembly accuracy and invariable movement.

[0007] By adopting the above technical solution, a slide rail and a slider are slidably connected on the support frame, thereby driving the counterweight plate to move back and forth and causing the seat back to move together. This enables more precise matching when installing different models of seats, improves the accuracy of seat assembly, and makes the operation of assembling seat backs easier.

[0008] Furthermore, a support column is disposed below the counterweight plate, and a hydraulic rod is fixedly connected to the support column, and a hydraulic cylinder is fixedly connected to the hydraulic rod.

[0009] By adopting the above technical solution, the hydraulic cylinder is activated to move the moving end of the hydraulic rod, which in turn moves the support column, thereby driving the counterweight plate to move. This works in conjunction with the slide rail and the slider to better support the counterweight plate and make the moving structure more stable.

[0010] Furthermore, four self-locking wheels are arranged at the four lower corners of the support frame. Each self-locking wheel includes a fixing plate, which is rotatably connected to a connecting frame, and the connecting frame is rotatably connected to rollers.

[0012] Furthermore, the connecting frame is rotatably connected to a pressing plate via fixing bolts, one end of the pressing plate is connected to a connecting piece, and the connecting piece is rotatably connected to a support foot via a rotating shaft.

[0013] By adopting the above technical solution, the installation of the pressure plate and support foot structure can better fix the assembly auxiliary device in the designated position, and can also easily switch between moving and fixed modes.

[0014] Furthermore, an auxiliary bracket is fixedly connected to one side of the counterweight plate, and an auxiliary roller is installed below the auxiliary bracket.

[0015] By adopting the above technical solution, an auxiliary support is added to the traditional device, which allows the assembly auxiliary device to be used stably and avoids the problem of tipping over when one side is under weight. The configuration of the auxiliary rollers allows the auxiliary support to be moved easily after the counterweight plate moves back and forth.

[0016] Furthermore, a support plate is fixedly connected to the lower part of the slide rail, a support rod is disposed below the support plate, a base is disposed below the support rod, and the lower part of the support plate is fixedly connected to the hydraulic cylinder.

[0017] By adopting the above technical solution, the stability of the assembly auxiliary device is enhanced, providing a stable structural support for the seat back assembly auxiliary device. A hydraulic cylinder is fixedly connected below the support plate, making the forward and backward movement structure more stable.

[0018] Furthermore, the lifting and fixing mechanism includes a connecting plate, a cylinder is installed at one end of the connecting plate, a drive rod is driven by the cylinder, a fixing plate is fixedly connected above the drive rod, and an auxiliary slide rod is configured on the connecting plate to assist the fixing plate in sliding.

[0019] By adopting the above technical solution, the cylinder drives the drive rod to raise and lower the fixed plate, and together with the hydraulic rod, slide rail one, and slide rail two, the assembly auxiliary device can more accurately complete the assembly of the seat back.

[0020] In summary, the present invention has the following main advantages: This utility model uses a slide rail, a slider, and a hydraulic cylinder to drive the counterweight plate to move back and forth, causing the seat back to move together. This enables more precise matching when installing different models of seats, improves the accuracy of seat assembly, and makes the assembly of seat back easier. The use of self-locking wheels can stably support the assembly auxiliary device, changing the traditional inconvenient structure and making movement and transportation more convenient.

[0021] This utility model, through the installation of the pressure plate and the support foot structure, can better fix the assembly auxiliary device in the designated position, and can easily switch between moving and fixed modes. Based on the traditional device, an auxiliary bracket is added, which allows the assembly auxiliary device to be used stably and avoids the problem of tipping over when one side is under weight. The configuration of the auxiliary rollers allows the auxiliary bracket to be moved easily after the counterweight plate moves back and forth. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment: A high-precision assembly auxiliary device for aircraft seat backrests, such as Figure 1-4 As shown, the device includes a support frame 1. Slide rails 102 are mounted on both sides of the upper part of the support frame 1. Slide rails 102 are slidably connected to sliders 2. A counterweight plate 3 is connected above slider 2. Slide rail 4 is mounted on one side of the upper part of the counterweight plate 3. Slide rail 4 is slidably connected to slider 12. A lifting and fixing mechanism 8 is fixedly connected above slider 12. The sliding connection between slide rails 102 and slider 2 on the support frame 1 causes the counterweight plate 3 to move back and forth, thus moving the seat backrest together. This allows for more precise matching when installing different seat models, improving seat assembly accuracy and making seat backrest assembly easier. It also makes the structure of the assembly auxiliary device more robust, improves the precision of aircraft seat backrest assembly, and enhances assembly quality.

[0026] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A support column 7 is arranged below the counterweight plate 3. A hydraulic rod 6 is fixedly connected to the support column 7. A hydraulic cylinder 5 is fixedly connected to the hydraulic rod 6. Activating the hydraulic cylinder 5 moves the moving end of the hydraulic rod 6, causing the support column 7 to move, thereby moving the counterweight plate 3. This works in conjunction with the slide rail 102 and the slider 2 to better support the counterweight plate 3 and make the moving structure more stable. This effectively improves the convenience and accuracy of the assembly auxiliary device, avoids the problem of the structure being unstable and easy to loosen, and makes the assembly process more efficient.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4The support frame 1 has four self-locking wheels 9 at its four lower corners. Each self-locking wheel 9 includes a fixing plate 901, which is rotatably connected to a connecting frame 905. The connecting frame 905 is rotatably connected to a roller 906. The four self-locking wheels 9 at the bottom can stably support the assembly auxiliary device, changing the traditional inconvenient structure and making it easier to move and transport. At the same time, the movement operation is very simple and convenient, avoiding the problem of difficult operation, and allowing the assembly auxiliary tool to move more flexibly.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting frame 905 is rotatably connected to the pressing plate 902 via fixing bolts. One end of the pressing plate 902 is connected to the connecting piece 903. The connecting piece 903 is rotatably connected to the support foot 904 via a rotating shaft. The installation of the pressing plate 902 and the support foot 904 structure can better fix the assembly auxiliary device in the designated position and can easily switch between moving and fixed modes. This avoids the problem of assembly deviation caused by device movement during assembly. At the same time, the easy switching between fixed and moving modes provides a lot of convenience.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An auxiliary support 10 is fixedly connected to the lower side of one side of the counterweight plate 3, and an auxiliary roller 11 is installed below the auxiliary support. The addition of the auxiliary support 10 on the basis of the traditional device allows the assembly auxiliary device to be used stably and avoids the problem of tipping over when one side is under weight. The configuration of the auxiliary roller 11 allows the auxiliary support 10 to move easily after the counterweight plate 3 moves back and forth; it reduces the phenomenon of the auxiliary support 10 getting stuck during movement and provides a stable structure for the assembly auxiliary device.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A support plate 101 is fixedly connected to the lower part of the slide rail 102. A support rod 103 is arranged below the support plate 101, and a base 104 is arranged below the support rod 103. The lower part of the support plate 101 is fixedly connected to the hydraulic cylinder 5, which enhances the stability of the assembly auxiliary device and provides stable structural support for the seat back assembly auxiliary device. The hydraulic cylinder 5 is fixedly connected to the lower part of the support plate 101, making the forward and backward movement structure more stable. This prevents the device from deviating from the assembly due to uneven ground, ensures the progress of the entire assembly process, and improves assembly efficiency.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4The lifting and fixing mechanism 8 includes a connecting plate 801. A cylinder 802 is installed at one end of the connecting plate 801. The cylinder 802 is connected to a drive rod 805. A fixing plate 803 is fixedly connected above the drive rod 805. The connecting plate 801 is equipped with an auxiliary slide rod 804 to assist the fixing plate 803 in sliding. The cylinder 802 drives the drive rod 805 to raise and lower the fixing plate 803. In conjunction with the hydraulic cylinder 5, slide rail 102, and slide rail 24, the assembly auxiliary device can more accurately complete the assembly of the seat back; reduce manual operation, make the assembly of the seat back more convenient, and ensure the accuracy of the assembly.

[0032] The implementation principle of this embodiment is as follows: First, move the high-precision assembly auxiliary device for the aircraft seat back to the designated position. Then, step on the pressure plate 902 to make the support foot 904 close to the ground and fix the device. Next, fix the seat back on the fixing plate 803. Then, start the hydraulic cylinder 5 to drive the counterweight plate 3 to move back and forth through the slide rail 102. At the same time, the auxiliary roller 11 drives the auxiliary bracket 10 to move easily. Start the slider 12 to move on the slide rail 4 to make the lifting and fixing mechanism 8 move left and right. Finally, start the cylinder 802 to move the drive rod 805 to drive the fixing plate 803 to move up and down to assemble the seat back. When the device needs to be moved, step on the pressure plate 902 again to raise the support foot 904 and move it.
