Research On The Electric Firing Mechanism Design For The Large Caliber Small Arms

At present,the large-caliber firearms are one of the main special operations equipment of various military powers,playing an irreplaceable role in anti-personnel and anti-light armor targets.With the continuous improvement of firearms strike performance,improving the long-range firing accuracy of large-caliber firearms has become a hot research field of various research institutions.The use of new sights composed of infrared,visible light and laser ranging is the main technical way to improve the accuracy of long-range shooting of large-caliber guns.By analyzing the key problems such as the trigger stroke detection and the electric shock control of the combination of gun and sight,the design scheme of the large-caliber firearm electric firing mechanism is proposed,The specific research contents are as follows.1.This thesis firstly carried out a more comprehensive analysis of domestic and foreign researches from three aspects: new sight technology,gun sight combined technology and electric firing technology.Then,according to the use characteristics of large caliber guns,the research about the design of the snapped and grip type electric firing mechanism are proposed.2.To the situation of the large-caliber gun equipment and the difficulty of combining new guns and sights,the design of the snap-in electric firing mechanism was studied.The design of the overall design was built and the three-dimensional model was built around the design requirements.The corresponding technical solutions are proposed for the firing mode conversion,the electric shock safety,the trigger stroke detection,and the electric shock.The total weight of the device is less than 0.2 kg and the outer dimensions are less than 45 x 60 x 60 mm.Under the premise of not making any changes to the firearm,it can be quickly installed in the trigger retainer position by the three-jaw elastic mechanism to realize the trigger stroke detection and electric firing of the large-caliber firearm.3.Launching trigger stroke detection and electric firing design on the structure of large-caliber firearms are important ways to develop intelligent firearms.In order to solve the problem of integrated design of large-caliber firearms,based on the full analysis of the structural characteristics and requirements of large-caliber firearms,the design research of the grip-type electric firing mechanism was carried out,the overall design model was constructed,and the trigger stroke detection was proposed.The technical measures of the design of the grip type electromagnet and the problem of electric shock safety make the scheme have the characteristics of high integration,uniform appearance and strong versatility.4.In order to accurately control the firing timing,shorten the firing delay,and meet the smoothness requirements of the electric firing mechanism,the manufacturing process design of the snap-in and grip-type electric firing mechanism is carried out,and the critical dimensions and tolerance requirements of the main components are determined,a more detailed processing route is developed with the actual process,the raw material types,blanking dimensions,processing equipment,tool parameters and so n are determined And the non-skeleton coils were wound and solved the problems of loose shelves and core pulling,which is the foundation for the trial production and assembly of parts.5.Electromagnet is not only the main component to achieve electric shock,but also the main source of energy consumption of the gun sight system.In order to meet the requirements of rapid firing,to further reduce the system energy consumption,to extend the working hours of the system,and to improve the battlefield adaptability of firearms,the electromagnet was modeled in three dimensions by using the ANSYS Electronics Desktop simulation software,which analyzed the electromagnetic force under different air gaps.The comparison between the simulation and the experiment results verified the correctness of the theoretical calculation of electromagnetic force,which provides a theoretical basis for the design and debugging of electromagnet.
