Modularly-designed fuse safety insurance mechanism

Abstract

The invention discloses a modularly-designed fuse safety insurance mechanism which is composed of three times of safety insurances, the first time of safety insurance is a recoil insurance; the secondtime of safety insurance is a centrifugal insurance; the third time of insurance is a long-distance insurance; and the three times of insurances and an explosion-proof sliding block form a main bodyof the safety insurance mechanism. At ordinary times, the explosion-proof sliding block is clamped by a recoil safety device composed of a cantilever beam mass block and a centrifugal safety device composed of a spring mass block, an explosion propagation sequence is separated, and the safety of a fuse is guaranteed. In the launching state, the safety insurance mechanism sequentially relieves thethree times of insurances by recognizing recoil force, centrifugal force and other environmental force, the explosive-proof sliding block relieves corresponding constraints, locking is completed, a detonating hole is aligned, and the safety insurance mechanism relieves the insurances. Based on the three-dimensional additive manufacturing technology, the size and the complexity of the safety insurance mechanism can be effectively reduced, the mechanism is convenient to assemble due to the modular design principle, and meanwhile the workload of optimization design of the mechanism in the futureis greatly reduced.

Description

technical field [0001] The invention belongs to the field of three-dimensional additive manufacturing and fuze safety insurance mechanism, in particular to a fuze safety mechanism with modular design three-dimensional additive manufacturing technology. Background technique [0002] Fuze technology is a high-tech research field integrating machinery, electronics, sound, magnetism, chemistry, computer and its composite technology. In recent years, with the development of three-dimensional additive technology, fuze design and processing and three-dimensional In theory and in reality, it becomes logical that the use of three-dimensional additive technology in the field of fuze can reduce the volume of the fuze, and at the same time facilitate the processing of complex structures and improve the integration of the fuze. Therefore, the application of three-dimensional additive technology in the fuze is a modern fuze. basis for development. The reduction of the volume of the fuze ...

Problems solved by technology

Since then, the structure of the security mechanism is complicated, and the requirements for processing and assembly are very high, which is easy to cause failure

At the same time, the safety device is not a modular design, but is designed separately and processed and assembled, which is not conducive to subsequent improvement

[0004] Both of the above two security mechanisms adopt the principle of parallel bomb axis placement, occupying too much axial space, which is not conducive to the full use of the fuze space, and the detonation sequence is not on the same straight line, which will lead to the loss of detonation energy. At the same time, MEMS technology The use of the security mechanism also makes the processing cycle of the security mechanism too long and the process is complicated, which is inconvenient to ensure the yield rate of the parts
