Connecting device for combined warhead

Abstract

The invention discloses a connecting device for a combined warhead. The middle part of a second upper end circular plane of an upper cover connecting frame is provided with a circle of second annularboss, the edge of a second lower end circular plane of the upper cover connecting frame is provided with second circular through holes which are uniformly distributed in the circumferential direction,the middle part of the second lower end circular plane of the upper cover connecting frame is provided with second circular blind holes which are uniformly distributed in the circumferential direction, and the side surface of the second annular boss of the upper cover connecting frame is a second outer cylindrical surface; after the upper end warhead is connected with the upper cover connecting frame, the upper cover connecting frame and a lower end connecting frame are provided with large chamfers, when the upper cover connecting frame and the lower end connecting frame are combined, the chamfers automatically correct the position accuracy, and after the upper cover connecting frame and the lower end connecting frame are coaxial, due to the fact that a seventh ball body of a ball body jacks up the upper cover connecting frame, the upper end warhead can freely rotate around an axis until a pin enters a pin hole, the circumferential angle position precision is guaranteed, and the timeis saved.

Description

technical field [0001] The invention belongs to the technical field of warheads, relates to a combined warhead, in particular to a connecting device for a combined warhead. Background technique [0002] Explosive warheads are the simplest of the explosive warheads. It consists of a large amount of high-explosive charge housed in a metal shell, relying on the blasting effect produced when the main charge explodes to destroy the target. [0003] Ying Guomiao and others reported in the document "The Current Situation and Development of Conventional Anti-ship Missile Warheads" (Sichuan Ordnance Journal, 2006, No. 3, p. 14): the damage power of the warhead is proportional to its mass and volume, At present, the main research direction of the warhead is implosion type and high power. However, with the increase in the size of the warhead, new problems have been encountered, such as increased difficulty in shell processing, increased difficulty in charging, and increased difficult...

AI Technical Summary

Problems solved by technology

[0005] (1) The upper warhead is placed on the end surface of the lower warhead, and mechanical connection is often no longer performed. When the test field is windy or the end surface is uneven, once it tilts, the upper warhead is easy to slip, which will cause danger

[0006] (2) Due to the large size of the upper warhead, when it is placed on the lower end surface, a crane is usually used to cooperate with the movement. The stroke error of the crane is relatively large. After the upper warhead is placed, the coaxiality accuracy with the axis of the lower warhead is poor. Large coaxiality error leads to poor axial symmetry, which affects the power of the warhead after explosion

[0007] (3) After the upper warhead is placed, the accuracy of the circumferential angle position with the lower warhead is poor, and a large circumferential angle error will affect the functional performance of the warhead and affect the power of the warhead after explosion

[0008] (4) Due to the weight of the upper warhead, when the displacement is carried out by a crane, the distance moved each time is relatively large, and the position accuracy of each adjustment is poor, requiring repeated adjustments, and the installation speed is slow, which wastes time
