Abstract

The invention discloses a sandwich type MEMS safety system integrated device. An integrated structure including a dual-end fixed limiting frame, an explosive-proof sliding block, an explosive-proof sliding block limiting pin, an explosive-proof sliding block limiting groove, an explosive-proof sliding block reverse buffer limiting groove, explosive-proof sliding block reverse buffer limiting combteeth, a rear base overload threshold value judging mechanism, a centrifugal overload threshold value judging mechanism, an explosion propagation hole, two flexible explosive-proof layers, an explosive-proof sliding block motion limiting device, an explosive-proof sliding block motion buffer area, an explosive-proof sliding block reverse buffer area, a first limiting device and a second limiting device is adopted in the device, and advantages of being small in size, low in power consumption, good in machining sample consistency and the like are achieved. The beneficial effects of being high insensory ability of ballistic trajectory environment, and high in work reliability of safe and protection relieving control system are achieved, meanwhile, a small fuse has the important significancein improving warhead charging, through the small fuse, the next-stage charging is improved, and the damage of a small-caliber cartridges can be improved.

Description

technical field [0001] The invention relates to the safety technology of small-caliber projectiles, in particular to a "sandwich" type MEMS safety system integration device and a method thereof. Background technique [0002] The micro-mechanical safety system widely used in small-caliber bullets mainly relies on high-precision machining technology to realize the processing and assembly of various sensitive components, but due to processing tolerances and errors in the assembly process cannot be avoided, the error magnitude reaches hundreds of microns . It is the main factor that seriously restricts the development of miniaturized fuze safety and release control. Consistency and yield are also susceptible to processing conditions, resulting in uneven product. Based on the above problems, the micro-electromechanical system MEMS security system for fuzes based on micro-nano processing technology with good consistency, extremely low processing errors and low assembly links has...
