Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and in particular to a full-size stringer forward placement device. Background Technology

[0002] In the process of manufacturing large aircraft, the use of stringers made of carbon fiber composite materials is increasing. In order to improve the structural strength of the stringers, full-size stringers are generally used for processing and manufacturing. Full-size stringers refer to stringer components that are completely consistent with the final dimensions, materials and structures defined on the aircraft design drawings. They can represent the performance of the final product and be directly used for aircraft assembly.

[0003] In related technologies, after the full-size stringer is formed, it is usually necessary to flip the stringer 180 degrees for subsequent handling, inspection and storage. For example, a T-shaped stringer needs to be flipped 180 degrees to form an inverted T-shape. This operation seems simple, but due to the large length, there may be risks of twisting, delamination or even deformation during the flipping process. In addition, the positional accuracy of the stringer is required before flipping, and it needs to be flipped in a set position. How to achieve convenient and accurate positioning of the stringer before flipping has become a technical problem that urgently needs to be solved. Utility Model Content

[0004] In view of at least one of the above technical problems, the present invention provides a full-size long stringer forward placement device, which adopts structural improvements to improve the convenience and accuracy of positioning the full-size long stringer.

[0005] According to a first aspect of the present invention, a full-size long stringer forward placement device is provided, comprising: A rolling bracket, wherein multiple rolling brackets are arranged at intervals along a straight line, and a roller is rotatably connected to the rolling bracket, wherein the rotation direction of the roller is toward the extension direction of the rolling bracket. A long stringer includes a support beam and a fixed seat disposed on the support beam, the fixed seat being used to fix the long stringer, and the long stringer being movably disposed on the rolling support. The positioning assembly includes a pushing drive fixed on the same side in the width direction of the rolling bracket, and an end abutment mechanism disposed at one end of the rolling bracket. The side of the rolling bracket away from the pushing drive is also provided with a side wall abutment.

[0006] Furthermore, multiple rolling supports are arranged along a straight line.

[0007] Furthermore, the supporting beam is a box beam, and both ends of the supporting beam have connecting flanges.

[0008] Furthermore, the end face of the connecting flange has a positioning hole that is adapted to the end abutment mechanism.

[0009] Furthermore, lifting seats are fixed on both sides of the box girder.

[0010] Furthermore, the fixing seat is perpendicular to the support beam, and the fixing seat has a mounting seat for mounting the stringer, the mounting seat having a slot adapted to the stringer.

[0011] Furthermore, the mounting base is detachably connected to the fixed base.

[0012] Furthermore, the end abutment mechanism includes a vertically arranged abutment bracket, a cylinder vertically fixed on the abutment bracket, and a stepped positioning post connected to the cylinder and passing through the abutment bracket, the end of the stepped positioning post being adapted to the positioning hole.

[0013] Furthermore, the end abutment mechanism also includes a slide rail arranged along the length direction of the rolling bracket and a slider that is slidably connected to the slide rail. The abutment bracket is fixed on the slider, and the abutment bracket also has a positioning drive for driving the abutment bracket to move.

[0014] The beneficial effects of this utility model are as follows: By setting up a long stringer support, the long stringer is always fixed on the long stringer support during movement, thereby reducing deformation or even damage to the long stringer during movement. The rollers mounted on the rolling support allow the long stringer support to move easily on the rolling support. The push drive components set on both sides of the rolling support and the side wall abutment settings allow the push drive components to push the long stringer support against the side wall abutment, thereby achieving positioning in the left and right directions.

[0021] like Figures 1 to 5 The full-size stringer forward placement device shown includes a rolling support 1, a stringer support 2, and a positioning assembly 3, as detailed below. Figure 1 and Figure 2As shown in the embodiment of this utility model, multiple rolling supports 1 are arranged at intervals along a straight line, and rollers 11 are rotatably connected to the rolling supports 1. The rotation direction of the rollers 11 is towards the extension direction of the rolling supports 1. The rollers 11 enable the long stringer 2 to move along the length direction of the rolling supports 1. The rolling supports 1 can be formed by welding or screwing together steel profiles. The long stringer 2 includes a support beam 21 and a fixing seat 22 disposed on the support beam 21. The fixing seat 22 is used to fix the long stringer. The long stringer 2 is movably disposed on the rolling supports 1. By setting the long stringer 2, the long stringer is fixed on the fixing seat 22. This arrangement can reduce the impact on the long stringer when moving the long stringer 2, thereby reducing the deformation or damage caused by the long stringer during subsequent flipping. The positioning component 3 includes a pushing drive 31 fixed on the same side in the width direction of the rolling supports 1, and an end abutment mechanism 32 disposed at one end of the rolling supports 1. A side wall abutment is also provided on the side of the rolling supports 1 away from the pushing drive 31. In the specific positioning process, the stringer is first fixed on the stringer support 2, then the stringer support 2 is moved to the rolling support 1, and then the stringer support 2 is pushed to the set position. Then, by the pushing drive 31 on the rolling support 1, the stringer support 2 is pushed against the side wall (not shown in the figure), thereby achieving the positioning of the stringer support 2 before flipping.

[0022] In the above embodiment, the long stringer 2 is fixed on the long stringer 2 during movement, thereby reducing deformation or even damage to the long stringer during movement. The roller 11 rotating on the rolling support 1 allows the long stringer 2 to move easily on the rolling support 1. The push drive 31 on both sides of the rolling support 1 and the side wall are respectively set, so that the push drive 31 pushes the long stringer 2 against the side wall, thereby achieving positioning in the left and right directions. The end abutment mechanism 32 is set to position the end of the long stringer 2, thereby achieving a unique positioning position for the long stringer 2, and thus improving the accuracy and convenience of positioning the long stringer 2 before flipping.

[0023] Based on the above embodiments, in some embodiments of this utility model, multiple rolling brackets 1 are arranged along a straight line. It should be noted that the specific number of rolling brackets 1 is determined according to the length of the full-size stringer, and in specific implementations, the total length of the rolling brackets 1 can be set to be slightly greater than the length of the stringer.

[0024] Please continue to refer to Figure 3In some embodiments of this utility model, the support beam 21 is a box beam, and both ends of the support beam 21 have connecting flanges 21a. By setting the connecting flanges 21a, additional box beams can be installed at both ends of the box beam as needed, so that the total length of the support beam 21 is adapted to the length of the stringer; in addition, in some embodiments of this utility model, the end face of the connecting flange 21a has a positioning hole, which is adapted to the end abutment mechanism 32.

[0025] In some embodiments of this utility model, such as Figure 3 As shown, lifting seats 21b are also fixed on both sides of the box girder. The lifting seats 21b are located on both sides of the box girder, allowing for convenient use of cranes or other lifting equipment to fix the entire truss support 2. Furthermore, in some embodiments of this invention, the fixing seat 22 is perpendicular to the support beam 21, and as shown... Figure 4 As shown, the fixed base 22 has a mounting base 221 for mounting the stringer, and the mounting base 221 has a slot 222 adapted to the stringer. For example, in some embodiments of this invention, the stringer is a T-shaped stringer, and the slot 222 can be configured to fit the middle vertical plate of the T-shaped stringer, which can be achieved by clearance fit or other pin methods, thereby improving the fixing reliability of the stringer. Furthermore, to further improve the adaptability of the stringer, in embodiments of this invention, the mounting base 221 is detachably connected to the fixed base 22. Thus, different mounting bases 221 can be replaced according to different stringer types, thereby maximizing the supporting effect of the support beam 21.

[0026] In embodiments of this utility model, in order to set different positioning positions in the length direction, such as Figure 2 and Figure 5 As shown, the end abutment mechanism 32 includes a vertically arranged abutment bracket 321, a cylinder 322 vertically fixed to the abutment bracket 321, and a stepped positioning post 323 connected to the cylinder 322 and passing through the abutment bracket 321. The end of the stepped positioning post 323 is adapted to the positioning hole. Through the arrangement of the cylinder 322 and the stepped positioning post 323, one side of the positioning post can abut against the abutment bracket 321, while the stepped positioning post 323 protruding from one side of the abutment bracket 321 cooperates with the positioning hole. Furthermore, in this embodiment of the invention, the cylinder 322 also has a buffering function to prevent damage to the positioning assembly 3 caused by the movement of the stringer bracket 2. Please continue to refer to... Figure 5In some embodiments of this utility model, the end abutment mechanism 32 further includes a slide rail 324 arranged along the length direction of the rolling bracket 1 and a slider 325 slidably connected to the slide rail 324. The abutment bracket 321 is fixed on the slider 325, and the abutment bracket 321 also has a positioning drive member 326 for driving the abutment bracket 321 to move. It should be noted that the positioning drive member 326 can take many forms, for example, it can be...
