The invention discloses an assembly structure and an assembly method of an integral filler of a throwing mechanism. An integral filler is provided in the peripheral gap of the pyrotechnic product of the throwing mechanism. The integral filler is divided into a lower section, a middle section and an upper section arranged from bottom to top, and the lower section and the middle section There is a fastening mechanism outside the joint and the joint between the middle section and the upper section, and a pressure plate is provided on the overall filler; the assembly structure is also provided with temporary accessories, including a protective cap and a temporary pressure plate on the head of the pyrotechnic product, and a set The upper pretensioning device and the lower pretensioning device on the outside of the pyrotechnic product, and the flexible protection device on the outer side of the lower middle and upper section of the integral filling. During specific assembly, the protective cap and temporary pressure plate are used for pre-locking, and then the lower section, middle section and upper section are installed in sequence, and the pre-tightening device, pyrotechnic product safety screw and flexible protection device are removed at different times, and the pressure plate and fastening mechanism are installed. Complete assembly to ensure product quality.
Description
technical field [0001] The invention relates to the technical field of throwing mechanisms, in particular to an assembly structure and an assembly method of an integral filler of a throwing mechanism. Background technique [0002] The gap between the pyrotechnic product and the support structure is filled with fillers when the dispensing mechanism of a warhead is assembled. The product design in the early stage is assembled with a block filler structure, and it is improved to an integral filler structure in the later stage. Since the overall filling material is rigid polyurethane foam, and the connection thickness at the weakest point is only 2mm, it is very prone to breakage or damage during the assembly process of the throwing mechanism, and cannot be assembled in the block filling mode. The assembly quality of the overall filler directly affects the throwing effect of pyrotechnic products, and it is necessary to develop a structure and method for easy assembly in order to...
