Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1-10 shown, an installation and positioning device for a composite material launch tube mounting seat includes:

[0029] A mounting frame 100 for positioning the mounting seat 500 to be installed;

[0030] A fastener 200 for fixing the mounting seat 500 to be installed on the mounting frame 100;

[0031] An upper positioning plate 300 and a lower positioning seat 400 are provided on the mounting frame 100, and the mounting seat 500 is fixed on the upper positioning plate 300 and the lower seat through the fastener 200.

[0032] Specifically, multiple groups of mounting seats 500 are arranged along the axial direction of the launch tube 700 (three groups are arranged in this embodiment), and multiple mounting seats 500 (four are arranged in this embodiment) are arranged along the circumferential direction of the launch tube 700. The mounting seat 500 includes an arc-shaped mounting portion 501 mounted on the surface of the launch tube 700 and a hollow square connecting portion 502. The connecting portion 502 adopting a hollow structure can further achieve weight reduction. At the same time, a plurality of special-shaped through holes are provided on the connecting portion 502; the mounting frame 100 is assembled and welded by square tubes, the lower positioning seat 400 is fixed on the mounting frame 100 (or can be designed as a part of the mounting frame 100 during design), and the upper positioning plate 300 is horizontally fixed on the mounting frame 100 (fixed by screws) and is located above the launch tube 700.

[0033] Furthermore, the fastener 200 includes a bolt 201, a nut 202 and a baffle 203.

[0034] It should be noted that directly using a conventional bolt 201 in cooperation with a nut 202 cannot achieve the installation of the fastener 200. Therefore, the baffle 203 is designed to cooperate with the bolt 201 and the nut 202 to complete the installation of the connecting portion 502 of the mounting seat 500 and the lower positioning seat 400, and the positioning position is adjusted before installation.

[0035] Further, a positioning block 205 is provided on the upper positioning plate 300. The positioning block 205 passes through the upper positioning plate 300 and is inserted into the mounting seat 500. The fastener 200 passes through the positioning block 205. Here, the fastener 200 does not need to be equipped with a nut 202, and a corresponding baffle 203 can be used to be threadedly connected with the bolt 201, and the fixing method can be adjusted according to actual needs.

[0036] It should be noted that due to the limitation of the mounting holes on the connecting portion 502 (the holes are too large), directly installing with the fastener 200 will affect the installation accuracy. Therefore, the positioning block 205 is designed, which can well limit the installation tightness accuracy between the connecting portion 502 and the positioning plate. During actual installation, a gasket 204 can be added between the upper positioning plate 300 and the mounting seat 500 to adjust the installation height.

[0037] Further, a positioning boss 401 inserted into the mounting seat 500 is provided on the top surface of the lower positioning seat 400.

[0038] It should be noted that, similarly to the above, the function of the positioning boss 401 is equivalent to that of the positioning block 205, further improving the installation accuracy between the mounting seat 500 and the lower positioning seat 400.

[0039] Further, an axial limiting plate 600 is also provided on the mounting frame 100, and a positioning pin 601 for connecting the end face of the launch cylinder 700 is provided on the axial limiting plate 600.

[0040] Specifically, the axial limiting plate 600 is installed at the end of the mounting frame 100.

[0041] It should be noted that in cooperation with the axial limiting plate 600, first, it can play a role in limiting and positioning the axial position. Second, the rotation of the launch cylinder 700 can be restricted through the positioning pin 601, further improving the assembly accuracy of the mounting seat 500.

[0042] The assembly process of the present utility model is as follows:

[0043] 1) Install the lower positioning seat 400 on the mounting frame 100, use the fastener 200 to clamp and fix the mounting seat 500, adjust the axial position, prevent the mounting seat 500 from moving due to operation during the installation process, and apply an adhesive to the joint surface between the mounting seat 500 and the launch cylinder 700;

[0044] 2) Lift and install the composite launch cylinder 700 above the lower positioning seat 400 and support it on the mounting seat 500;

[0045] 3) Install the axial limiting plate 600 on the mounting frame 100;

[0046] 4) Adjust the axial position of the launch cylinder 700 so that the end face of the launch cylinder 700 is in close contact with the axial limiting plate 600, and insert the positioning pin 601;

[0047] 5) Install the positioning plate 300 on the mounting frame 100;

[0048] 6) After applying adhesive to the mating surface between the upper positioning plate 300 and the launch tube 700, install the mounting seat 500 on the upper positioning plate 300 through the fasteners 200 in cooperation with the positioning block 205;

[0049] 7) Clean the excess adhesive on the surfaces of the composite launch tube 700 and the mounting seat 500, and promptly use the adhesive to repair the lack of adhesive at the gap between the mounting seat 500 and the composite launch tube 700. Apply fillet treatment with the adhesive at the edges of the parts;

[0050] 8) After standing still until the adhesive is cured, drill the installation holes for the fasteners 200 in the composite launch tube 700 through the connection holes on the surface of the mounting seat 500. Finally, use the fasteners 200 to fix the mounting seat 500 on the surface of the mounting tube.

[0051] The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
