A Reversible Motion Fuze Flameproof Mechanism Driven by DC Motor
In view of the need of fuze life safety and the shortcomings of existing recoverable and isolated flame-proof mechanism related technology,of which the continuous movement of the slider cannot be restored to the ready state again,a motion reversible fuze flameproof mechanism driven by DC motor was proposed.The DC motor was connected with the lead screw through the reducer.The detonation tube moved in a straight line through the sleeve on the lead screw.The motor was turned forward,the detonation tube was completely ex-tended,and the flameproof mechanism was in the ready state;The motor was reversed,the detonation tube was retracted,and the flameproof mechanism was in a safe state.At the same time,Hall encoder was used to feed-back the location of detonation tube in real time to ensure the stable operation of the mechanism.The mechanism could realize the fuze switch between the safe state and the ready state and the fuze delay release isolation,had the advantages of low cost,simple structure,high utilization rate of space.
