Electromechanical composite safety mechanism

Abstract

The invention discloses an electromechanical composite safety mechanism, relates to the technical field of fuses. The invention aims to solve the problem that the fuses are low in reliability and safety under the condition of launching overload. The electromechanical composite safety mechanism comprises a mechanism body, a vertical groove is formed in the mechanism body, a guide seat is mounted in the vertical groove, one end of a rear seat cylinder is slidably inserted into the guide seat, a steel ball hole is formed in the rear seat cylinder, a steel ball is installed in the steel ball hole, a protruding rod is integrally formed at the other end of the rear seat cylinder, a limiting plate and a rear seat spring are movably connected to the protruding rod in a sleeving mode, the end, away from the rear seat cylinder, of the protruding rod penetrates through a groove formed in a check ring, the end, away from the rear seat cylinder, of the protruding rod is located below the check ring, a sliding block is installed at the bottom of the mechanism body, a transverse groove is further formed in the mechanism body, and an electric actuator is installed in the transverse groove. The rear seat cylinder is locked by the steel ball when recovered, the reliability is high, the reliability of the fuses is improved, the mechanism has a fault safety design, and the safety of the fuses is improved.

Description

technical field [0001] The invention relates to the technical field of fuzes, in particular to an electromechanical composite insurance mechanism. Background technique [0002] As an important component of the fuze system, the insurance mechanism is mainly used to ensure the safety of the fuze during service handling and projectile launching. How to improve the safety of the fuze is the most concerned point of all types of ammunition. [0003] All types of ammunition will basically produce launch overload when fired. In order to satisfy the requirement that the fuze can be reliably disarmed under launch overload and realize the function of failure insurance, a set of electromechanical composite insurance mechanism is designed. Contents of the invention [0004] The purpose of the present invention is to solve the problem of low reliability and safety of the fuze under launch overload, and propose an electromechanical composite insurance mechanism. The recoil cylinder of t...
