Description

Technical Field

[0001] The utility model belongs to the technical field of composite material shell manufacturing, and particularly relates to an integrated winding tooling for an engine shell nozzle. Background Art

[0002] Since the 1980s, carbon fiber composite materials have been used in the solid engine shells of various tactical missiles (such as the US Trident-II submarine-launched ballistic missile and the French M51 ballistic missile). The shell is connected to the metal flange on the nozzle through a metal head.

[0003] With the development of society, the existing solid engine shells are gradually turning to the integrated technology of composite material engine shell nozzles, which mainly involves integrating the design of the engine and the corresponding aircraft into a common structure. Through optimized design and material selection, the efficiency and light weight of the structure are achieved, and the negative weight can be further reduced by about 10% on the basis of the traditional composite material engine shell.

[0004] Generally, high-performance carbon fiber composite material winding technology is used for the engine shell, but the traditional metal connection method is still adopted, which easily leads to the inability of the traditional winding tooling to position the nozzle and is difficult to disassemble.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0040] As Figures 1 to 17 shown, an integrated winding tooling for an engine housing and nozzle of an embodiment of the present utility model includes a mandrel 1. An engine housing winding tooling is installed at the upper end of the mandrel 1, and an engine nozzle winding tooling is installed on the engine housing winding tooling. The engine housing winding tooling and the engine nozzle winding tooling form an integrated winding tooling for the engine housing and nozzle. The combination of the two can not only wind the engine housing, but also realize the integrated winding of the engine housing and the nozzle, and has the advantages of simple structure, low tooling cost, convenient disassembly and demolding, etc.

[0041] As Figures 1 to 9As shown in the figure, the engine nozzle winding tooling includes a plurality of first mounting members 2. The first mounting members 2 are mounted on the mandrel 1. A plurality of positioning convex portions 101 are fixedly connected to the mandrel 1. The positioning convex portions 101 play a positioning role.

When the first mounting members 2 are installed, they are inserted from one end of the mandrel 1, and the positioning grooves are matched with the positioning convex portions 101, so as to realize the positioning installation of the first mounting members 2.

[0042] As Figures 1 to 4 shown in the figure, a first shell plate 5 and a second shell plate 7 are respectively mounted on two first mounting members 2. A third shell plate 9 is mounted between the first shell plate 5 and the second shell plate 7. The mandrel 1, the first mounting members 2, the first shell plate 5, the second shell plate 7, and the third shell plate 9 form the engine nozzle winding tooling. Winding is carried out on the nozzle winding tooling to finally form a hoop 4. Then, the engine nozzle winding tooling is installed on the nozzle winding tooling formed with the hoop 4, and winding is carried out again. After demolding, an integrally wound workpiece of the engine housing nozzle is obtained.

A plurality of fourth mounting holes 8011 are formed in the reinforcement plate 801, and the fourth mounting holes 8011 are respectively located on both sides of the second reinforcing rib 802. The fourth mounting holes 8011 on both sides of the second reinforcing rib 802 respectively correspond to the second shell plate 7 and the third shell plate 9 or the first shell plate 5 and the third shell plate 9. A plurality of fifth mounting holes 8021 are formed in the second reinforcing rib 802, and a plurality of side mounting holes 301 matching the fifth mounting holes 8021 are formed in the first reinforcement frame 3. Mounting parts can be installed in the side mounting holes 301 and the fifth mounting holes 8021 to realize the fixation of the second reinforcement frame 8 and the first reinforcement frame 3.

[0048] As Figures 7 to 8 shown, to further improve the strength of the first shell plate 5 and the second shell plate 7, first reinforcing ribs 6 are installed in both the first shell plate 5 and the second shell plate 7. The strength of the first shell plate 5 and the second shell plate 7 can be increased through the first reinforcing ribs 6, and the service life of the first shell plate 5 and the second shell plate 7 can be improved, thereby improving the service life of the engine housing winding tooling.

[0049] A number of support structures or strengthening structures are also provided between the third shell plate 9 and the mandrel 1 to reduce the deformation of the third shell plate 9 by providing the support structures or strengthening structures. Among them, the support structure can specifically be the combination of the first reinforcement frame 3 and the second reinforcement frame 8. One end of the first reinforcement frame 3 is fixed to the mandrel 1, and the second reinforcement frame 8 is fixedly installed at the end of the first reinforcement frame 3 away from the mandrel 1, and the second reinforcement frame 8 is in contact with the inner wall of the third shell plate 9. The support structure is arranged circumferentially to completely support the third shell plate 9.

[0050] As Figures 1 to 9As shown, the strengthening structure includes strengthening edges 13. A number of seventh mounting holes 1301 are opened on the strengthening edges 13. A plurality of thirteenth mounting holes matching the seventh mounting holes 1301 are opened on the third shell plate 9. Mounting members are installed in the thirteenth mounting holes and the seventh mounting holes 1301. The third shell plate 9 and the strengthening edges 13 are fixed through the mounting members. The number of strengthening edges 13 is two. The two strengthening edges 13 form an annular structure matching the inner diameter of the third shell plate 9, playing a role in strengthening the structural strength of the third shell plate 9. Of course, the number of strengthening edges 13 can also be multiple, and can be specifically customized according to actual operation requirements.

[0051] As Figures 1 to 5 shown, the third shell plate 9 includes an inverted V-shaped shell plate 10, two bevel shell plates 11 matching the inverted V-shaped shell plate 10, and a number of straight shell plates 12.

After the first shell plate 5 and the second shell plate 7 are fixed, install the third shell plate 9 between the two second strengthening frames 8, and the installation of the engine housing winding tooling can be completed. It should be noted that during the installation of the third shell plate 9, a strengthening edge 13 also needs to be installed inside the third shell plate 9 to play a role in strengthening the structural strength of the third shell plate 9.

[0053] The steps for installing the third shell plate 9 are as follows: First, fix the two ends of the inverted V-shaped shell plate 10 to the second strengthening frame 8 respectively. Then, install the bevel shell plates 11 at both ends of the inverted V-shaped shell plate 10, and ensure that the side walls of the bevel shell plates 11 are in contact with the side walls of the inverted V-shaped shell plate 10. Finally, install the straight shell plates 12 in sequence along the outer wall of one bevel shell plate 11, so that the straight shell plates 12 are arranged in a circle and finally contact one side surface of the other bevel shell plate 11.
