Forming device for improving precision on basis of laser range finder

Abstract

The invention discloses a forming device for improving precision on the basis of a laser range finder. A circle of second annular boss is arranged in the middle of the second upper end circular planeof an upper cover connecting frame, second circular through holes evenly distributed in the circumferential direction are formed in the edge of the second lower end circular plane of the upper cover connecting frame, second circular blind holes evenly distributed in the circumferential direction are formed in the middle of the second lower end circular plane of the upper cover connecting frame, and the side surface of the second circular boss of the upper cover connecting frame is a second outer cylindrical surface. According to the forming device, after an upper end warhead is connected withthe upper cover connecting frame, the upper cover connecting frame and a lower end connecting frame are both provided with large chamfers, when the upper cover connecting frame and the lower end connecting frame are combined, the chamfers automatically correct the position precision, after the upper cover connecting frame and the lower end connecting frame are coaxial, the upper cover connecting frame is jacked up by a seventh ball body of a ball body, and the upper end warhead can rotate freely around the axis until a pin enters a pin hole, so that the circumferential angle position precisionis guaranteed, and the time is saved.

Description

technical field [0001] The invention belongs to the technical field of warheads, and relates to a combined warhead, in particular to a molding device based on a laser range finder to improve precision. 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 the Warhead of Conventional Anti-ship Missiles" (Sichuan Ordnance Journal, 2006, No. 3, p. 14): the damage power of the warhead is proportional to its mass and volume. The main research direction of the warhead is implosion 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 ...

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
