A fuze swing actuator

Abstract

The invention discloses a fuse swinging execution mechanism belonging to the field of fuse safety mechanisms. The fuse swinging execution mechanism is formed by connecting at least one actuation unit in series, wherein each actuation unit comprises a transmission end, a swinging rod, a fixed end, dielectric elastomers, conductive paste and pressing plates; a U-shaped groove is formed in a rotary end; a connection shaft is inserted into the U-shaped groove; the rotary end is connected with one end of the swinging rod through the connection shaft and can rotate around the swinging rod; the other end of the swinging rod is fixedly connected with the fixed end; the dielectric elastomers are symmetrically arranged on both sides of the rotary end and the fixed end; the pressing plates are arranged at adhesion parts between the outer surfaces of the dielectric elastomers and the rotary and fixed ends; the inner and outer surfaces of the dielectric elastomers are coated with the conductive paste, and the conductive paste is connected with an external power supply through a wire; the rotary end of the previous actuation unit serves as the fixed end of the subsequent actuation unit. The fuse swinging execution mechanism can swing horizontally, and has the characteristics of simple structure, high impact resistance, light weight, repeatable detection, high swinging and actuation speed, and large swinging angle.

Description

technical field [0001] The invention relates to the technical field of fuze insurance mechanisms, in particular to a fuze swing actuator. Background technique [0002] Fuze generally has two or more insurance agencies to ensure its safety. At present, the safety mechanisms used in electromechanical fuzes in China mainly use electromagnetic locking mechanisms, gunpowder actuators, or torque motors. The above-mentioned safety mechanisms can only move in a straight line and cannot swing. The single movement form restricts the overall development of the fuze. Using the electromagnetic locking mechanism alone cannot meet the safety of service handling when falling. After long-term vibration, there are problems of high working voltage and mutual adhesion between moving parts; the gunpowder actuator cannot be tested and is expensive; the torque motor requires a large installation space. Contents of the invention [0003] The object of the present invention is to provide a fuze s...

Problems solved by technology

At present, the safety mechanisms used in electromechanical fuzes in China mainly use electromagnetic locking mechanisms, gunpowder actuators, or torque motors. The above-mentioned safety mechanisms can only move in a straight line and cannot swing. The single movement form restricts the overall development of the fuze.

Using the electromagnetic locking mechanism alone cannot meet the safety when the service is dropped. After long-term vibration, the working voltage is too high and there are problems of mutual adhesion between the moving parts; the gunpowder actuator cannot be tested and is expensive; the torque motor requires a large installation space
