Description

Technical Field

[0001] This utility model belongs to the field of assembly auxiliary platform technology, and in particular relates to an aircraft assembly auxiliary installation platform. Background Technology

[0002] Aircraft assembly is a core process in the aerospace manufacturing industry, directly affecting the structural strength, aerodynamic performance, and flight safety of the entire aircraft. The process encompasses multiple stages, including component positioning, connection, testing, and debugging, demanding extremely high precision, efficiency, and safety. To adapt to complex assembly requirements, the industry has gradually introduced auxiliary installation platforms. These platforms, serving as the core carrier of assembly operations, must support the parts to be assembled and the personnel, while also possessing a certain degree of positional adjustment capability to accommodate the spatial requirements of different aircraft models and assembly processes. They assist in achieving precise positioning and efficient installation of components, serving as key tooling equipment connecting design drawings and physical products.

[0003] Existing aircraft assembly auxiliary installation platforms still have many shortcomings that make it difficult to meet actual needs. Most platforms have limited adjustment functions, with only basic lifting or horizontal movement capabilities and lacking flexible tilting and adjustment mechanisms. When encountering obstacles such as fuselage protrusions or pipeline interfaces during the assembly process, they cannot avoid obstacles by tilting the platform. They need to manually move parts or adjust their working posture, which not only reduces assembly efficiency but also easily affects assembly accuracy due to improper operation. Utility Model Content

[0004] The purpose of this utility model is to provide an aircraft assembly auxiliary installation platform, which solves the problems of existing related installation platforms being large in size, inconvenient to avoid obstacles, and limited in adaptability to various scenarios.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an auxiliary installation platform for aircraft assembly, comprising two symmetrically arranged columns, a bearing mechanism slidably mounted on one side of the two columns, the bearing mechanism comprising symmetrically arranged side support plates, two horizontal plates fixedly mounted vertically between the two side support plates, two lugs fixedly mounted on one side of one horizontal plate, a rotating shaft rotatably mounted between the two lugs, a base plate fixedly mounted on the circumferential side of the rotating shaft, two first guide rails fixedly mounted on the top of the base plate, and a bearing platform slidably mounted on the two first guide rails.

[0007] The present invention is further configured such that two second guide rails are fixedly installed on the bottom of the base plate, and a first hinge seat is slidably installed on the second guide rails; two second hinge seats are fixedly installed on one side of the other horizontal plate; and a connecting rod is rotatably installed between the first hinge seat and the second hinge seat.

[0008] The present invention is further configured such that a connecting plate is fixedly connected between the two first hinge seats, and a first screw rod rotatably installed on the bottom of the base plate is threaded through the connecting plate.

[0009] The present invention is further configured such that a second screw is rotatably mounted on the top of the base plate, and a connecting plate fixed to the bottom of the bearing platform is threaded through the circumferential side of the second screw.

[0010] The present invention is further configured such that a driving mechanism is fixedly installed on one side of the base plate, and the two output ends of the driving mechanism are respectively fixedly connected to the first screw and the second screw.

[0011] The present invention is further configured such that a belt conveyor is fixedly installed on the outer side of both columns, and a clamping plate is fixedly installed on the belt conveyor, and the clamping plate is fixedly connected to the side support plate.

[0012] This utility model has the following beneficial effects:

[0013] This utility model uses a belt conveyor and clamping plate to drive the bearing mechanism to rise and fall vertically along the column. Combined with the drive mechanism, it drives the second screw to move the bearing platform horizontally along the first guide rail. Then, relying on the linkage of the first screw, connecting plate, connecting rod and other components, the bearing platform can be rotated around the axis. It has multi-dimensional adjustment functions of height, horizontal position and rotation angle, which can flexibly adapt to different working positions and obstacle avoidance requirements in the aircraft assembly process, effectively expanding the platform's adaptability scenarios.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0024] Please see Figure 1-4 This utility model is an auxiliary installation platform for aircraft assembly, including two symmetrically arranged columns 1. A bearing mechanism 2 is slidably installed on one side of the two columns 1. The bearing mechanism 2 includes two symmetrically arranged support plates 3. Two horizontal plates 4 are fixedly installed between the two support plates 3 in a vertical direction. Two lugs 5 are fixedly installed on one side of one horizontal plate 4. A rotating shaft 6 is rotatably installed between the two lugs 5. A base plate 7 is fixedly installed on the side of the rotating shaft 6. Two first guide rails 8 are fixedly installed on the top of the base plate 7. A bearing platform 9 is slidably installed on the two first guide rails 8.

[0025] The column 1 provides vertical support for the entire auxiliary installation platform, ensuring the stability of the overall structure. The load-bearing mechanism 2 is the core working component, with its two side support plates 3 used to build the load-bearing frame. The two horizontal plates 4 connect and reinforce the two side support plates 3, while also providing the installation foundation for subsequent parts. The lugs 5 are fixed on the horizontal plates 4 to enable the rotation installation of the pivot 6. The pivot 6 serves as the rotation fulcrum of the base plate 7, allowing the base plate 7 to rotate around its axis. The base plate 7 provides the installation carrier for the load-bearing platform 9 and other bottom parts. The first guide rail 8 provides guidance for the sliding of the load-bearing platform 9, ensuring that the load-bearing platform 9 can move smoothly along a fixed trajectory. The load-bearing platform 9 is used to place the aircraft parts to be assembled and to provide a standing space for the operators, providing direct operating space for aircraft assembly operations.

[0026] Specifically, two second guide rails 10 are fixedly installed at the bottom of the base plate 7, and a first hinge seat 11 is slidably installed on the second guide rails 10. Two second hinge seats 12 are fixedly installed on one side of another horizontal plate 4. A connecting rod 13 is rotatably installed between the first hinge seats 11 and the second hinge seats 12. A connecting plate 14 is fixedly connected between the two first hinge seats 11, and a first screw 15 rotatably installed at the bottom of the base plate 7 is threaded through the connecting plate 14. The second guide rails 10 provide precise guidance for the sliding of the first hinge seats 11, preventing the first hinge seats 11 from deviating when sliding. The first hinge seats 11 are used for... The connecting rod 13 and the connecting plate 14 are used to transmit force. The second hinge seat 12 is fixed on the horizontal plate 4 and serves as the fixed rotation fulcrum of the connecting rod 13. The connecting rod 13, through its fixed length, converts the sliding of the first hinge seat 11 into a thrust on the base plate 7. The connecting plate 14 can synchronously drive the two first hinge seats 11 to move, ensuring that the force on both sides is balanced and avoiding unilateral offset that could cause the flipping to jam. The first screw 15, through the thread transmission principle, converts its own rotation into the linear movement of the connecting plate 14, providing a power source for the sliding of the first hinge seat 11, thereby driving the subsequent flipping action.

[0027] A second screw 16 is rotatably mounted on the top of the base plate 7. A connecting plate 17 fixed to the bottom of the bearing platform 9 is threaded through the side of the second screw 16. The second screw 16 drives the connecting plate 17 to move in a straight line by rotating, thereby synchronously driving the bearing platform 9 to slide along the first guide rail 8, realizing the horizontal position adjustment of the bearing platform 9 to meet the needs of aircraft assembly operations in different positions.

[0028] A drive mechanism 18 is fixedly installed on one side of the base plate 7. The two output ends of the drive mechanism 18 are fixedly connected to the first screw 15 and the second screw 16 respectively. The drive mechanism 18 serves as a power output source and consists of a motor and a reducer. It provides rotational power to the first screw 15 and the second screw 16 through its two output ends.

[0029] Both columns 1 are fixedly mounted with belt conveyors 19 on their outer sides. Clamping plates 20 are fixedly mounted on the belt conveyors 19 and are fixedly connected to the side support plates 3. The belt conveyors 19 drive the clamping plates 20 to move vertically through their own transmission function. The clamping plates 20 are fixedly connected to the side support plates 3, thereby synchronously driving the side support plates 3 and the entire load-bearing mechanism 2 to rise and fall vertically along the columns 1, realizing the adjustment of the height of the load-bearing platform 9 and meeting the needs of aircraft assembly operations at different heights.

[0030] The operation process of this embodiment is as follows: During use, the aircraft parts to be assembled are placed on the support platform 9. The operator stands on the support platform 9 and starts the belt conveyor 19. The belt conveyor 19 drives the side support plate 3 to move vertically along the column 1 via the clamping plate 20, adjusting the support mechanism 2 to a suitable assembly height. If it is necessary to adjust the horizontal position of the support platform 9, the drive mechanism 18 is started. The drive mechanism 18 drives the second screw 16 to rotate. The second screw 16 drives the connecting plate 17 to move via threaded transmission. The connecting plate 17 then drives the support platform 9 to move. Platform 9 slides along the first guide rail 8 to the target position; when it is necessary to avoid obstacles during the assembly process, the drive mechanism 18 is activated to drive the first screw 15 to rotate. The first screw 15 drives the connecting plate 14 to move through the thread transmission. The connecting plate 14 simultaneously drives the two first hinge seats 11 to slide along the second guide rail 10. Since the length of the connecting rod 13 is fixed, one end of the connecting rod 13 rotates around the second hinge seat 12, and the other end applies an upward oblique thrust to the base plate 7 through the first hinge seat 11, pushing the base plate 7 to rotate around the axis of the rotating shaft 6, thereby causing the bearing platform 9 to flip and achieve obstacle avoidance.
