Description

Technical Field

[0001] The invention relates to an automatic blind-installation plug-in device and method for a pyrotechnic transducer assembly, and is particularly suitable for aligning and plugging a pyrotechnic transducer assembly with a plug pin in a deep hole, and belongs to the field of aerospace pyrotechnic device assembly. Background Art

[0002] The pyrotechnic transducer assembly is an internal assembly of a space pyrotechnic device, which quickly converts electrical energy into thermal energy for detonating energetic materials. The energetic materials explode to produce high-temperature and high-pressure combustion gases, converting chemical energy into thermal energy. The combustion gases can ignite the propellants in missiles or rockets. Pyrotechnic transducer assemblies are widely used in various fields of aerospace vehicles and play an important role. For ease of assembly, the pyrotechnic transducer assembly and the shell assembly are assembled by pin and socket docking. In order to ensure the reliability of the docking assembly between the pyrotechnic transducer assembly and the shell assembly so as to ensure that the pyrotechnic device can complete the predetermined function, it is necessary to measure the matching dimensions of the pyrotechnic transducer assembly and the shell assembly, identify the position of the pyrotechnic transducer assembly pin and the shell assembly socket, align and insert them, apply a certain pressure to push the pyrotechnic transducer assembly, and measure the dimensions after assembly to ensure that there is no gap between the pyrotechnic transducer assembly and the shell assembly. However, since the socket of the shell component is located in a deep hole, the original method was to manually observe the position of the pyrotechnic transducer component pin and the position of the shell component socket, clamp the pyrotechnic transducer component so that the pyrotechnic transducer component pin is docked with the shell component socket in the deep hole. During the docking process, the docking of the pin and the socket cannot be observed, and unsuccessful docking often occurs, resulting in rework, which has a negative impact on the on-time delivery and assembly quality of the aerospace pyrotechnic device. At the same time, the position of the pyrotechnic transducer component pin and the shell component socket are interference fits, and the pyrotechnic transducer component is manually pushed and pressed. If the pushing speed is too fast, metal scraps will be generated between the pin and the socket, which will affect the assembly quality of the aerospace pyrotechnic device. In addition, at this stage, the measurement dimensions are recorded manually in a paper notebook and manually calculated. The recording method is backward, which causes the operator to pause frequently, resulting in low assembly efficiency. Summary of the invention
