Description

Technical Field

[0001] The invention relates to the technical field of composite material manufacturing, and in particular to a long stringer positioning tool and a long stringer positioning method. Background Art

[0002] Composite panels are commonly used in aircraft. In the production of panels and doors, composite reinforced panels with long-string structures are often used to improve the overall strength, rigidity and stability of the panels and doors. Most of the fuselage loads are transmitted through the panels. As the longitudinal structural parts of the fuselage, the long stringers mainly bear the axial force caused by the bending of the fuselage. In addition, they also have a certain supporting effect on the panels, increasing the critical stress of the panels under compression and shear instability. The accuracy of the position of the long stringers relative to the panels greatly affects the overall structural performance of the fuselage panels.

[0003] The long stringers and the wall panels are usually fixed with adhesive film, and the position of the long stringers relative to the wall panels needs to be positioned during the bonding process. When positioning the long stringers, due to the inconsistent curvature of the shape of the hatch at different positions, there is no corresponding reference when the long stringers are glued to the wall panels. In the prior art, multiple workers are required to adjust the positioning equipment between the multiple long stringers, which is inconvenient to operate and it is difficult to ensure the accurate spacing between the front and rear ends of the multiple long stringers. It is impossible to accurately position the position of the long stringers relative to the wall panels, which affects the overall structural performance of the wall panels. In addition, the existing positioning equipment is heavy and usually requires the use of special hoists. The positioning operation is difficult, which leads to a decrease in production efficiency.

[0004] Therefore, there is an urgent need for a long-beam positioning tool and a long-beam positioning method to solve the above-mentioned problems existing in the prior art. Summary of the invention

[0073] Embodiment 1

[0074] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a long stringer positioning tool for positioning the installation position of the long stringer 100 on the wall panel 200. Specifically, the long stringer positioning tool includes a positioning main beam 1, an installation positioning component 2, a first limiting component 3 and a second limiting component 4.

[0075] Among them, see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The positioning main beam 1 extends along the length direction of the wall panel 200 and is compatible with the extension direction of the installation surface of the wall panel 200 for installing the long girder 100. Both ends of the positioning main beam 1 are connected with installation positioning components 2. The installation positioning components 2 are configured to be connected to the wall panel 200 with adjustable installation height. When the installation positioning components 2 are adjusted, the positioning main beam 1 can be driven to rise and fall. The first limiting component 3 is connected to the positioning main beam 1, and the first limiting component 3 is used to clamp the long girder 100 in the width direction of the long girder 100; the second limiting component 4 is connected to the positioning main beam 1, and for each long girder 100 to be installed, the first limiting component 3 and the second limiting component 4 are provided. The second limiting component 4 includes an axial limiting member 41 and a clamping mechanism 42. The axial limiting member 41 can cooperate with the long girder 100 to position the long girder 100 relative to the positioning main beam 1 in the axial direction of the long girder 100, and the clamping mechanism 42 is used to clamp and fix the long girder 100.

[0076] The long girder positioning tool provided in the embodiment of the present application, when positioning and installing the long girder 100 on the wall panel 200, the entire positioning tool is positioned and connected to the wall panel 200 by installing the positioning component 2, and then the height of the installation positioning component 2 relative to the wall panel 200 is adjusted so that the positioning main beam 1 drives the first limiting component 3 and the second limiting component 4 to be raised by a certain distance, so as to facilitate the positioning and connection fixation between the long girder 100 and the positioning tool. By setting the first limiting component 3 that engages the long girder 100 in the width direction of the long girder 100, the position of the long girder 100 in its width direction can be positioned, and the long girder 100 after positioning can be prevented from shifting in the width direction. By setting the axial limiting member 41, the position of the long girder 100 in its axial direction can be positioned, and the long girder 100 after positioning can be prevented from moving in its axial direction. By setting the clamping mechanism 42, the long girder 100 can be clamped and fixed, so as to realize the fixed connection between the long girder 100 and the positioning tool. That is, the first stopper assembly 3 and the second stopper assembly 4 of the positioning tool can be combined to position the long stringer 100 in the axial direction and the width direction of the long stringer 100, and determine the accurate installation position of the long stringer 100 on the wall panel 200. After the long stringer 100 is positioned, the installation positioning assembly 2 is adjusted to drive the positioning main beam 1 to fall into place, so that the long stringer 100 falls on the wall panel 200, and the bonding and fixing between the long stringer 100 and the wall panel 200 is completed.

[0077] The long stringer positioning tool and long stringer positioning method provided in the embodiment of the present application can conveniently and accurately locate the installation position of the long stringer 100 on the wall panel 200, improve the convenience of positioning, reduce the difficulty of positioning and improve the positioning accuracy, which helps to improve the overall structural performance of the wall panel 200 and improve production efficiency.

[0078] Specifically, see Figure 1 The mounting surface of the wall panel 200 for mounting the long stringer 100 is a concave curved surface, on which a plurality of long stringers 100 are arranged at intervals to enhance the structural performance of the wall panel 200. An overlap plane is provided at both ends of the concave curved surface, and the mounting and positioning components 2 at both ends of the positioning main beam 1 are both overlapped and connected to the overlap planes at both ends of the wall panel 200.

[0079] In the embodiments of the present application, Figure 5 and Figure 6As shown, the installation and positioning assembly 2 includes a mounting plate 21, a positioning pin 22 and an adjusting bolt 23. The mounting plate 21 is connected to the end of the positioning main beam 1, and a first positioning hole 2121 is provided on the mounting plate 21, and a second positioning hole 201 is provided on the wall panel 200. The positioning pin 22 is passed through the first positioning hole 2121 and the second positioning hole 201 to locate the connection position of the entire tooling on the wall panel 200, so as to improve the positioning accuracy of the subsequent long stringer 100. The height of the mounting plate 21 relative to the wall panel 200 can be adjusted. During the height adjustment process, the mounting plate 21 can slide vertically with the positioning pin 22 through the first positioning hole 2121. That is to say, the axes of the first positioning hole 2121 and the second positioning hole 201 are both vertical, and the positioning pin 22 is vertically arranged. By setting the positioning pin 22, on the one hand, the installation position of the tooling on the wall panel 200 can be quickly and accurately positioned, and on the other hand, the vertical movement of the positioning main beam 1 can be guided so that the positioning main beam 1 slides along the trajectory of the positioning pin 22. The position accuracy of the tooling relative to the wall panel 200 can also be guaranteed during the vertical position adjustment process.

[0080] In this embodiment, the height adjustment of the mounting plate 21 is achieved by adjusting the bolts 23. Specifically, the adjusting bolts 23 are threaded on the mounting plate 21 and can be rotatably pressed against the wall panel 200. After the positioning pin 22 is passed through the first positioning hole 2121 and the second positioning hole 201, the height of the mounting plate 21 relative to the wall panel 200 can be adjusted by screwing the adjusting bolts 23, so that the mounting plate 21 drives the positioning main beam 1 to be raised or lowered relative to the wall panel 200.

[0081] Furthermore, the positioning pin 22 can be a stepped positioning pin 22, with a small bottom diameter and a large top diameter, which is convenient for inserting into the first positioning hole 2121, and has good strength and is not easy to bend and deform. An operating rod can be set at the top of the positioning pin 22, and the operating rod is set at an angle with the positioning pin 22, which is convenient for operators to disassemble and install the positioning pin 22.

[0082] Of course, the positioning pin 22 may also be a cylindrical pin with a constant cross-sectional area. There is no limitation on its shape and structure here, as long as the first positioning hole 2121 and the second positioning hole 201 can be penetrated.

[0083] More specifically, the mounting plate 21 includes a first plate body 211 and a second plate body 212 arranged at an angle. The first plate body 211 is connected to the end of the positioning main beam 1, and the second plate body 212 is provided with the above-mentioned first positioning hole 2121, and the adjusting bolt 23 is screwed on the second plate body 212. By setting the first plate body 211 and the second plate body 212 at an angle, it is easier to achieve the connection between the mounting plate 21 and the positioning main beam 1 and the wall panel 200, and the structural layout is more reasonable. The first plate body 211 and the second plate body 212 are vertically connected or approximately vertically connected, and the two can be welded or directly bent into one piece, which is not limited here.

[0084] Continue reading Figure 5 and Figure 6 The installation and positioning assembly 2 further includes a first fastener 24, and the mounting plate 21 is detachably connected to the wall panel 200 through the first fastener 24. After the clamping mechanism 42 clamps and fixes the long stringer 100 on the tooling, the adjusting bolt 23 is screwed to lower the mounting plate 21 and the positioning main beam 1 into place, and then the mounting plate 21 is connected to the wall panel 200 through the first fastener 24. After the long stringer 100 is firmly bonded to the wall panel 200, the first fastener 24 can be removed.

[0085] Exemplarily, the first fastener 24 is a threaded fastener such as a bolt or a screw, which is securely connected and easy to operate.

[0086] like Figure 6 As shown, multiple adjusting bolts 23 can be provided, for example, two, and the multiple adjusting bolts 23 are symmetrically distributed relative to the positioning pin 22 to ensure that when the height is adjusted, the mounting plate 21 and the positioning main beam 1 can be raised or lowered evenly and stably.

[0087] Furthermore, a plurality of first fasteners 24 are provided, for example, two, four, six, etc., and the plurality of first fasteners 24 are symmetrically distributed relative to the positioning pins 22, ensuring a firm connection and balanced force between the mounting plate 21 and the wall panel 200, so that the positioning main beam 1 can firmly press the long girder 100 onto the wall panel 200, thereby achieving a firm bonding between the long girder 100 and the wall panel 200.

[0088] like Figure 7 As shown, the first limit assembly 3 includes a fixed clamping plate 31 and a movable clamping plate 32. The fixed clamping plate 31 is fixedly connected to the positioning main beam 1; the movable clamping plate 32 is movably connected to the positioning main beam 1, and the movable clamping plate 32 has a clamping position and an escape position, and can switch between the clamping position and the escape position. Figure 7In the engaging position shown, it and the fixed clamping plate 31 are respectively attached to the two sides of the long stringer 100 in the width direction to position the long stringer 100 in the width direction and limit the movement of the positioned long stringer 100 in the width direction. Before the long stringer 100 is placed between the fixed clamping plate 31 and the movable clamping plate 32, the movable clamping plate 32 is driven to move toward the avoidance position relative to the positioning main beam 1 to move away from the fixed clamping plate 31 to avoid the long stringer 100, so that the long stringer 100 is smoothly placed in place and attached to the fixed clamping plate 31. After the long stringer 100 is attached to the fixed clamping plate 31 and the long stringer 100 is limited by the second limiting assembly 4, the movable clamping plate 32 is placed in the engaging position to position the long stringer 100.

[0089] In some embodiments of the present application, in order to realize the movement of the movable clamping plate 32 between the engaging position and the avoiding position, such as Figure 7 As shown, the first limiting assembly 3 further includes a second fastener 33 and a mounting shaft 34. The movable clamping plate 32 is rotatably connected to the positioning main beam 1 through the mounting shaft 34, and the second fastener 33 is detachably arranged to penetrate and connect the movable clamping plate 32 and the positioning main beam 1. After the second fastener 33 is removed from the movable clamping plate 32, the movable clamping plate 32 can be flipped up, so that the movable clamping plate 32 rotates relative to the positioning main beam 1 around the axis of the mounting shaft 34 to avoid the long stringer 100, so that the long stringer 100 can be smoothly fitted with the fixed clamping plate 31.

[0090] Exemplarily, the second fastener 33 is a threaded pin, which is threadedly connected to the movable clamping plate 32 and can be passed through and fixed to the positioning main beam 1, or the threaded pin passes through the movable clamping plate 32 and is threadedly connected to the positioning main beam 1, both of which can fix the movable clamping plate 32 in the engaging position.

[0091] Alternatively, in some embodiments of the present application, the first position-limiting assembly 3 may include a third fastener, and the movable clamping plate 32 is detachably connected to the positioning main beam 1 through the third fastener. When the long stringer 100 needs to be placed, the third fastener is removed to remove the movable clamping plate 32 from the positioning main beam 1. After the long stringer 100 is fitted with the fixed clamping plate 31, the movable clamping plate 32 is fixedly connected to the positioning main beam 1 through the third fastener. To further prevent the movable clamping plate 32 from rotating, two third fasteners may be provided to connect the movable clamping plate 32 and the positioning main beam 1.

[0092] Exemplarily, the third fastener is a fastener such as a bolt or a screw.

[0093] Alternatively, in some embodiments of the present application, the first limit assembly 3 may include a fourth fastener, a sliding portion is provided on the movable clamping plate 32, and a guide structure is provided on the positioning main beam 1. The movable clamping plate 32 can slide along the guide structure to the avoidance position through the sliding portion, and the fourth fastener is detachably connected to the movable clamping plate 32 and the positioning main beam 1. When the long stringer 100 needs to be placed, the fourth fastener is removed to make the sliding portion on the movable clamping plate 32 slide along the guide structure in a direction away from the fixed clamping plate 31, specifically Figure 7 In the embodiment, the movable clamping plate 32 can slide to the left to avoid the long stringer 100 and reserve a space sufficient to accommodate the long stringer 100. After the long stringer 100 is fitted with the fixed clamping plate 31, the movable clamping plate 32 is slid along the guide structure to the engaging position, and the movable clamping plate 32 is locked on the positioning main beam 1 by the fourth fastener.

[0094] Exemplarily, the sliding part is a sliding column, the guiding structure is a guiding groove, the sliding column is located in the guiding groove, and is slidably matched with the guiding groove. The fourth fastener is a fastener such as a bolt or a screw.

[0095] like Figure 7 As shown, the first limiting assembly 3 further includes a fifth fastener 35. The fixed clamping plate 31 is connected to the positioning main beam 1 through at least two fifth fasteners 35 arranged at intervals, so that the position of the fixed clamping plate 31 remains fixed and does not deviate or rotate relative to the positioning main beam 1. Exemplarily, the fifth fastener 35 is a fastener such as a bolt or a screw.

[0096] See also Figure 4 and Figure 7 The second limiting assembly 4 includes an extension plate 43, which is connected to the positioning main beam 1 and extends along the width direction of the positioning main beam 1. Specifically, one end of the extension plate 43 is connected to the positioning main beam 1 through a connecting plate, and the connecting plate and the extension plate 43 generally form an L-shaped plate, and the other end of the extension plate 43 extends to the end of the long stringer 100. In order to ensure that the connection between the extension plate 43 and the positioning main beam 1 is stable and reliable, a reinforcing rib 44 is provided between the extension plate 43 and the connecting plate.

[0097] Both ends of the long stringer 100 are provided with ear pieces 101, and ear holes are provided on the ear pieces 101. The axial limiter 41 is penetrated through the extension plate 43 and the ear hole to locate the position of the long stringer 100 in the axial direction, which is convenient to operate and accurate in positioning. Exemplarily, the axial limiter 41 is a limit pin.

[0098] See also Figure 4 and Figure 7The clamping mechanism 42 includes an adjusting portion 421 and a claw portion 422. The adjusting portion 421 is screwed onto the extension plate 43. The claw portion 422 is connected to one end of the adjusting portion 421. When the adjusting portion 421 is screwed, the adjusting portion 421 can drive the claw portion 422 to rise or fall. After the axial limit member 41 is penetrated through the ear hole of the ear piece 101, the adjusting portion 421 is screwed so that the claw portion 422 and the extension plate 43 clamp the ear piece 101 together, so that the long stringer 100 is hung on the positioning main beam 1, completing the fixed connection between the long stringer 100 and the positioning tooling.

[0099] Further, see Figure 7 At least one clamping mechanism 42 is disposed on both sides of the axial stopper 41 along the width direction of the extension plate 43, and the two clamping mechanisms 42 clamp the ear piece 101 together to improve the clamping stability and reliability. Exemplarily, two clamping mechanisms 42 are disposed on each extension plate 43, and the two clamping mechanisms 42 are disposed on both sides of the axial stopper 41 to clamp and fix the ear piece 101 in the width direction of the ear piece 101.

[0100] like Figure 3 As shown, two sets of positioning tools are used to position the installation position of the long stringer 100 on the wall panel 200, wherein the clamping mechanism 42 of one set of positioning tools clamps the ear piece 101 at one end of the long stringer 100, and the clamping mechanism 42 of the other set of positioning tools clamps the ear piece 101 at the other end of the long stringer 100.

[0101] The long stringer positioning tool provided in the embodiment of the present application has a reasonable structural design and strong operability. The position of the long stringer after installation can meet the coaxiality deviation requirement. It also has a simple structure, light weight and is easy to operate.

[0102] Embodiment 2

[0103] This embodiment provides a long stringer positioning method, which is applied to the long stringer positioning tool as described in the first embodiment above, and includes the following steps:

[0104] S1, connecting the long stringer positioning tool to the wall panel 200 by installing the positioning assembly 2. Specifically, insert the positioning pin 22 into the first positioning hole 2121 on the mounting plate 21 and the second positioning hole 201 on the wall panel 200.

[0105] S2. Adjust the height of the installation positioning assembly 2 relative to the wall plate 200 so that the positioning main beam 1 is raised relative to the wall plate 200. Specifically, screw the adjusting bolt 23 into the installation plate 21, and tighten the adjusting bolt 23 so that the positioning main beam 1, the first limiting assembly 3, and the second limiting assembly 4 are all raised relative to the wall plate 200.

[0106] S3. Applying adhesive film to the bonding surface of the long stringer 100 to be installed.

[0107] S4, insert the long stringer 100 into the first limiting assembly 3, so that the first limiting assembly 3 limits the long stringer 100 in the width direction of the long stringer 100. Specifically, the movable clamping plate 32 is moved to the avoidance position to put the long stringer 100, and the side of the long stringer 100 is made to fit with the fixed clamping plate 31 to determine the position of the long stringer 100 in the width direction.

[0108] S5. Position the axial position of the stringer 100 through the axial stopper 41. Specifically, adjust the stringer 100 to a rough position, insert the axial stopper 41 into the ear hole on the ear piece 101 at the end of the stringer 100, so as to determine the axial position of the stringer 100.

[0109] S6. Clamp and fix the long stringer 100 by the clamping mechanism 42. Specifically, the adjusting portion 421 is screwed so that the claw portion 422 and the extension plate 43 clamp the ear piece 101 together, and the ear pieces 101 at both ends of the long stringer 100 are clamped by the corresponding clamping mechanism 42 so that the long stringer 100 is hung on the long stringer positioning tool.

[0110] S7, returning the movable clamping plate 32 to the engaging position, and completing the fixation of the long stringer 100 on the positioning tool.

[0111] S8, adjust the height of the installation and positioning assembly 2 relative to the wall panel 200, so that the positioning main beam 1 falls into place relative to the wall panel 200. Specifically, screw the adjustment bolt 23 to make the installation plate 21 and the positioning main beam 1 fall, driving the long stringer 100 to fall onto the wall panel 200.

[0112] S9, the installation and positioning assembly 2 and the wall panel 200 are fixedly connected, so that the long stringer 100 is bonded and fixed to the wall panel 200 through the adhesive film. Specifically, the installation plate 21 and the wall panel 200 are fixedly connected by the first fastener 24, so that the long stringer 100 is pressed against the wall panel 200, and a stable bonding is achieved between the long stringer 100 and the installation surface of the wall panel 200.

[0113] Through the above steps, the positioning and bonding installation of the long stringer 100 on the wall panel 200 can be realized. After the bonding of the long stringer 100 is completed, the positioning tooling needs to be disassembled, and the steps are as follows:

[0114] S10 , after the long stringer 100 is bonded in place, the second fastener 33 is disassembled to loosen the movable clamping plate 32 , thereby releasing the clamping of the long stringer 100 by the first limiting assembly 3 .

[0115] S11 , releasing the clamping mechanism 42 from clamping the ear piece 101 of the stringer 100 , and removing the axial limiting member 41 .

[0116] S12, dismantling the first fastener 24 to release the fixed connection between the mounting plate 21 and the wall plate 200.

[0117] S13, screw the adjusting bolt 23 into the mounting plate 21 to raise the mounting plate 21 and the positioning main beam 1 relative to the wall plate 200.

[0118] S14. Remove the long girder positioning tooling.

[0119] At this time, the long stringer 100 is bonded to the wall panel 200 through the adhesive film, and the long stringer positioning tool does not participate in the subsequent curing process.
