Description

Letter fitting assembling device and process

Technical Field

The invention relates to a letter fitting assembling device and a process.

Background

Fuzes are important components in ammunition, and are final execution devices for the ammunition to exert a final effect, and the success or failure of the action directly determines the success or failure of an ammunition system against a target. The fuse structure design mainly firmly connects all the components of the fuse into a whole, so that the fuse forms a good pneumatic appearance, has enough strength, rigidity and stability, and can bear and transfer various loads possibly encountered in the whole life cycle of ammunition. At present, the structure design of the fuze mainly adopts the steps of fastening all components of the fuze on a frame, and then installing and fastening the frame in a cabin. Although the function of the fuse structure can be met according to the design method of the current fuse structure, the space utilization rate is not high under the same constraint of pneumatic appearance conditions; on the contrary, under the condition of meeting the same functions, the volume is increased, thereby leading to the increase of the mass. This form of construction is not adaptable to the direction of development of modern weapon systems that are miniaturized, lightweight, high-performance, modular.

How to provide a millimeter wave fuze, how to realize the quick and firm anti-loosening installation of the millimeter wave fuze, how to realize the automatic installation and assembly of each component, and how to realize the technical problem that the quick installation and the quick installation become urgent needs to be solved.
