Problems solved by technology
The manual assembly of micro-engines requires a large amount of assembly and the assembly process is very cumbersome, which will inevitably lead to time-consuming and labor-intensive phenomena, and because the grains in the micro-engines have high friction sensitivity, the assembly speed should not be too fast, and manual During assembly, the tightening speed of the nozzle and igniter cannot be controlled. If the speed is slightly faster, the possibility of detonating the powder column will increase, and the personal safety of the assembly workers will be threatened.
The bigger problem is that for propellants with a high burning rate, the assembly workers need to be in close contact with the tiny engines during the assembly process, which will also pose a great threat to the personal safety of the assembly workers

Embodiment Construction
[0023] Such as figure 1 Shown, pyrotechnic product miniature engine comprises the combustion chamber 9, igniter 4 and nozzle pipe 3 that rely on screw connection together, and wherein nozzle pipe external thread is connected with combustion chamber nozzle internal thread, igniter external thread and the ignition of combustion chamber internal thread connection.
[0024] Such as figure 2 and image 3 As shown, the automatic assembly device for pyrotechnics micro-engines includes a swing unit, a control motor 17, a driving gear 13 and a driven gear 12 arranged in the pyrotechnics assembly area. The output end of the control motor 17 transmits power to the driven gear 12 through the driving gear 13; the combustion chamber 9 passes through the end face of the driven gear 12 and is fixed at the center of the driven gear 12, and rotates coaxially with the driven gear 12 ;
[0025] The swing unit includes a swing cylinder 5, an upper needle cylinder 7, a lower needle cylinder 1,...

The invention discloses an automatic assembling device for an initiating explosive device micro-miniature engine. The automatic assembling device for the initiating explosive device micro-miniature engine comprises a swinging unit, a control motor, a driving gear and a driven gear which are arranged inside an initiating explosive device assembling area; an output end of the control motor transmits power to the driven gear through the driving gear; a combustion chamber is fixed in the center of the driven gear and the combustion chamber and the driven gear rotate coaxially; the swinging unit enables an upper rotary arm and a lower rotary arm to swing in and swing out inside and outside the assembling area under the function of a swinging air cylinder; an igniter is arranged below the upper rotary arm; a spray pipe is arranged above the lower rotary arm. According to the automatic assembling device for the initiating explosive device micro-miniature engine, a tedious mode of manually assembling the micro-miniature engine is changed to be a mechanical assembling mode, the labor workload of workers is greatly reduced, the assembling efficiency is improved, and risks during assembling of the initiating explosive device micro-miniature engine is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of pyrotechnics assembly, and relates to an automatic assembly device for a micro-engine of pyrotechnics. Background technique [0002] At present, the assembly of pyrotechnic micro-engines still relies on manual assembly, and there are many deficiencies in manual assembly. The manual assembly of micro-engines requires a large amount of assembly and the assembly process is very cumbersome, which will inevitably lead to time-consuming and labor-intensive phenomena, and because the grains in the micro-engines have high friction sensitivity, the assembly speed should not be too fast, and manual During assembly, the tightening speed of the nozzle and igniter cannot be controlled. If the speed is slightly faster, the possibility of detonating the powder column will increase, and the personal safety of the assembly workers will be threatened. The bigger problem is that for propellants with a high burning rate, th...
