A small solid rocket motor nozzle cap automatic assembly device

Abstract

A small-sized solid rocket motor nozzle cap automatic assembly device, belonging to the field of pyrotechnics mechanical parts assembly, including a base plate (1), a cap storage mechanism (2), a double-station cap transfer mechanism (3), an automatic coating The glue mechanism (4), the nozzle clamping limit mechanism (5), and the cap storage mechanism (2) are arranged on the bottom plate (1) to provide caps for the double-station cap transport mechanism (3); The station cap transport mechanism (3) is used to transport the caps in the cap storage mechanism (2) to the automatic gluing mechanism (4) for gluing, and to transport the glued caps to the nozzle clamping limit. The plugging mechanism (5) is used to paste and compact the plug; the automatic gluing mechanism (4) is used to automatically apply glue to the outer conical surface of the plugging; the nozzle clamping limit mechanism (5) is used to make the nozzle The nozzle is clamped and positioned vertically upwards, and at the same time, cooperate with the double-station blocking cap handling mechanism (3) to vertically put the glued blocking cap into the inner conical surface of the nozzle for bonding and compacting.

Description

technical field [0001] The invention relates to an automatic assembling device for a small-sized solid rocket motor nozzle plugging cover, which belongs to the field of assembling mechanical parts of pyrotechnics. Background technique [0002] The plug is an important part of the small solid rocket motor. It plays the role of sealing and moisture-proof during storage and flight; when the small solid rocket motor is ignited, it plays the role of quickly establishing the ignition pressure, shortening the ignition delay time and improving the ignition reliability. [0003] The blocking cover is a conical single-layer aluminum alloy thin-walled structure, and the outer conical surface is painted with epoxy resin glue to cooperate with the inner conical surface of the nozzle. The sealing performance and pressure bearing capacity after pasting are the key to assembly control. If the seal of the plug is poor, the internal charge will be damp. In addition, the low pressure bearing ...

AI Technical Summary

Problems solved by technology

At present, glue brushing and pasting are performed manually, which has the following problems: 1. The amount of manual glue brushing and the consistency of the pressure of the compacted plug during pasting are difficult to control, resulting in difficulty in the consistency of the sealing performance and pressure bearing capacity of the plug after pasting control

2. The nozzle hole is deep and the diameter of the mouth is small, which makes manual pasting difficult. It needs auxiliary tooling to complete the pasting, and the assembly efficiency is low.
