Abstract

The invention provides a solid rocket motor grain clearing device. The device comprises a lathe bed and a cushion frame arranged below the lathe bed; a headstock is arranged on the lathe bed, and a speed regulation motor for driving an output shaft to rotate and a belt wheel train matched with the speed regulation motor are arranged in the headstock; the output shaft is connected with a three-jawchuck, one end of the transition tool is clamped by the three-jaw chuck, and the other end of the transition tool is clamped at the grain end opening of the solid rocket motor; and a cantilever cutterbar is installed on the lathe bed through a feeding structure, a clamping part for clamping an inner hole turning tool is arranged at one end of the cantilever cutter bar, and the feeding structure is used for controlling the longitudinal or transverse movement of the inner hole turning tool. The clearing device can thoroughly remove the solid rocket motor grain and can recycle the cleared grain,so that the clearing device is more environment-friendly, and the efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of solid rocket motor manufacturing, in particular to a solid motor grain cleaning device. Background technique [0002] The disposal of decommissioned solid engine grains (composite solid propellant) has been receiving much attention. The first-generation open-air combustion and the second-generation controlled combustion methods are limited, and the third generation characterized by safer and more effective recycling The waste treatment method of energetic materials has become a research hotspot. It mainly adopts extraction (including supercritical extraction) and high-pressure water jet to remove the solid motor charge mode, the extracted components are purified and then reused, and the cut pieces are crushed to make industrial explosives; or the ammunition is cut with high-pressure liquid nitrogen. Extraction and high-pressure water jet methods are relatively mature at present, but they cannot fully rec...
