Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a light multi-tube composite fixer structure. Background Art

[0002] Existing multi-tube launcher setters mostly use single-tube independent setters or multi-tube composite setters. Single-tube independent setters have simple structure and light weight, but the circuit is relatively complex and very cumbersome to install; multi-tube composite setters have circuits concentrated inside the setter, which is easy to install, but the gaps between the coil sleeves need to be filled with epoxy resin, which requires more epoxy resin protective glue to be poured, and the weight is heavier. Utility Model Content

[0003] In view of this, the utility model provides a lightweight multi-tube composite fixer structure, which can reduce the weight of the existing multi-tube composite fixer.

[0004] The utility model is realized by the following technical solutions:

[0009] The filling piece includes a central filling piece and a plurality of side seam filling pieces, wherein the plurality of side seam filling pieces are filled between the outer circumference of the coil sleeve and the inner wall of the square frame, and the central filling piece is filled in the central part of all the coil sleeves;

[0010] The front cover is processed with a plurality of circular mounting holes B corresponding to the positions of the coil sleeves and a mounting interface hole corresponding to the position of the mounting interface; the front cover is fixed to the front face of the square frame and closes the front face of the square frame, so that the inner wall surface of the square frame, the outer circumferential surfaces of all the coil sleeves, the outer circumferential surface of a mounting interface, the inner surface of the front cover and the inner surface of the rear cover form a closed cavity, the filling piece is located in the closed cavity, and the remaining cavities in the closed cavity except for the filling piece are poured with epoxy resin.

[0011] Furthermore, the number of the coil sleeves is eight, and the corresponding eight circular mounting holes A and one mounting interface are arranged in a 3*3 matrix, and the mounting interface is located at the center of the matrix.

[0012] Furthermore, the central filling piece is a cross-shaped structure, a through hole passing through the mounting interface is processed in the center of the cross-shaped structure, and each end of the cross-shaped structure is located between the three coil sleeves.

[0013] Furthermore, a gap for installing the coil is reserved between each filling piece and the outer circumferential surface of the coil sleeve.

[0014] Furthermore, each filling piece is a hollow plastic piece formed by 3D printing.

[0015] Furthermore, a glue injection port is processed on one side of the square frame; when injecting epoxy resin, the injection is performed through the glue injection port of the square frame.

[0016] Beneficial effects:

[0017] (1) The utility model replaces epoxy resin with a filler in the multi-tube composite setter to reduce the filling amount of the protective glue, which can reduce the weight of the multi-tube composite setter structure. The shooting test has verified that the strength can meet the use requirements while reducing the weight.

[0018] (2) Each end of the central filling piece of the utility model is located between three coil sleeves, and a gap for installing the coil is left between each filling piece and the outer circumferential surface of the coil sleeve, and space for wiring is left inside, which can reduce the weight while protecting the coil circuit.

[0019] (3) The filling piece of the utility model is a hollow plastic piece formed by 3D printing. The hollow plastic piece is used to replace the original glue filling solution, that is, the hollow plastic piece is added to reduce the filling amount of the protective glue, which greatly reduces the weight of the multi-tube composite fixer.
