A Modular Design of Fuze Security Mechanism

Abstract

The invention discloses a fuze safety insurance mechanism with modular design, which is composed of three safety insurances, wherein the first safety insurance is recoil insurance; the second safety insurance is centrifugal insurance; and the third safety insurance is long-distance insurance. The three-way insurance together with the explosion-proof slider constitutes the main body of the safety insurance mechanism. In normal times, the explosion-proof slider is stuck by the recoil insurance composed of the cantilever beam mass block and the centrifugal insurance composed of the spring mass block, which cuts off the explosion transmission sequence and ensures the safety of the fuze. When in the launch state, the safety insurance mechanism will release the three insurances in turn by identifying environmental forces such as recoil force and centrifugal force, the explosion-proof slider will release the corresponding constraints, complete the lock, the blast hole is aligned, and the safety insurance mechanism will release the insurance. Based on the three-dimensional additive manufacturing technology, the invention can effectively reduce the volume and complexity of the safety insurance mechanism, and the principle of modular design also makes the mechanism easy to assemble, and at the same time greatly reduces the workload of optimizing the design of the mechanism in the future.

Description

Technical field [0001] The present invention belongs to the field of three-dimensional additive manufacturing and the imposing safety insurance institution, in particular a modular design three-dimensional additive manufacturing technology. Background technique [0002] Introduction of the promotion technology is a high-tech research field integrating machinery, electronic, sound, magnetic, chemical, computer and its composite technology. In recent years, with the development of three-dimensional additive technology, the provisional design processing and three-dimensional additive manufacturing are in theory. Upper and reality have become uncomfortable, and the use of three-dimensional additive technology can reduce the volume of the trusted area, which is convenient for processing complex structures, improves the integration of the letter, so the application of three-dimensional additive technology in therapeutic application is modern. The foundation of development. The reductio...

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, which occupies 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
