Abstract

The invention relates to the technical field of projectile body structural design, in particular to an explosive bolt acquirer. The explosive bolt acquirer comprises a support and an installation bolt, the support is in an inversed-n shape and comprises a base plate and two side plates, the side plates and the two ends of the base plate are integrally molded, the upper ends of the side plates extend to the outer sides to be provided with end edges, and installation holes are formed in the end edges; the installation bolt penetrates the installation holes to be connected with a shell end frame so that the support can be fixed to the lower surface of the shell end frame, the base plate is provided with a buffer hole, and a bolt head of an explosive bolt is located between the two side plates and is embedded into the buffer hole. Compared with a traditional explosive bolt acquiring structure, the explosive bolt acquirer is convenient and rapid to install, the design, analyzing and testing cost is reduced, projectile body structural design quick response and cost reduction are achieved, material selecting and machining can be separated from material selecting and machining of a projectile body overall bin, the machining difficulty is reduced, selectable materials are many, the production efficiency is improved, productization is facilitated, and the large-batch production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of projectile structure design, in particular to an explosive bolt catcher. Background technique [0002] At present, the separation between missile stages is a necessary link in the flight process, and the separation between missile stages can be divided into point separation and line separation. Explosive bolt is the most widely used point separation device with relatively mature technology, and it is the key component to realize the separation between missile stages. During the flight of the explosive bolt, the reliable connection of the front and rear compartments is firstly realized, and the explosive fracture occurs at a specific moment, so as to realize the reliable separation of the two connected compartments. After the explosion, the bolt is divided into two parts, usually called the bolt head and the screw. During the explosive separation process, a high-speed explosion impact will be formed, and...
