The utility model relates to a double-seal structure seal ring assembly tool suitable for limited space, which is composed of four parts: a guide head, a far port assembly shaft, a near port assembly shaft and an outer pusher sleeve. When the double-seal structure is located in a limited space, hands cannot pass through, and the double-seal structure is invisible, so the installation of the double-seal structure sealing ring cannot be completed. This tool uses the guide head to install the sealing ring on the far-mouth assembly shaft, and the far-mouth assembly shaft can accurately locate the far-mouth sealing groove, and the sealing ring can be accurately installed to the far-mouth sealing groove through the push-out sleeve. Similarly, use the guide head to install the sealing ring on the near-mouth assembly shaft, and the near-mouth assembly shaft can accurately locate the near-mouth sealing groove, and accurately install the sealing ring to the near-mouth sealing groove through the push-out sleeve. The sealing ring assembling tool of the double sealing structure of the present invention can complete the precise installation of the sealing ring of the double sealing structure under the condition that the space is too narrow to be manually installed or not visible. Compared with the existing installation method, the damage of the sealing ring is avoided, and the reliability of the sealing is improved.
Description
technical field [0001] The invention relates to a solid rocket motor, in particular to a double-seal structure sealing ring assembly tool suitable for limited space. Background technique [0002] The sealing ring is one of the important parts of the solid rocket motor. It keeps the high-temperature and high-pressure gas of the engine sealed in the internal space, and avoids the formation of a gas channel with the outside world to cause ablation and crossfire of the structure. Structural ablation and cross-fire of solid rocket motors will cause major structural damage or even explosion, so the sealing structure of solid rocket motors is required to have high reliability. [0003] A small solid rocket motor has a compact structure, and the sealing structure is designed in a limited space that cannot be seen or touched. In the current design state, if the sealing ring is assembled and then the double-seal structure is installed in a narrow space, the sealing ring may be damage...
