Abstract

The invention discloses a multi-station tightening device for assembling an external thread initiating explosive device. The multi-station tightening device comprises a base and a control system. A positioning protrusion corresponding to a part to be assembled is arranged at the bottom end of the base, a plurality of mounting holes with openings facing the bottom end are distributed in the outer side portion of the base, sliding sleeves fixed relative to the hole walls are arranged in the mounting holes, torque motors are mounted in the sliding sleeves, and the torque motors can axially slide in a limited mode along the inner walls of the sliding sleeves. The output end of the torque motor is connected with a torsion polished rod, a linear bearing is installed between the torsion polished rod and the inner wall of the installation hole, and the bottom end of the torsion polished rod is located outside the installation hole to be connected with an external thread initiating explosive device. And the control system controls the start and stop of the torque motor and the magnitude of the output torque. The torsion polish rod transmits power of the torque motor to the external thread initiating explosive device needing to be tightened, the purpose of tightening the external thread initiating explosive device into a to-be-machined part is achieved through rotation, the assembly efficiency is high, and consistency is good.

Description

technical field [0001] The invention relates to the technical field of automatic assembly of pyrotechnics, in particular to a multi-station tightening device for assembling external threaded pyrotechnics. Background technique [0002] In the production and assembly of pyrotechnic products, automatic or semi-automatic production lines have been gradually started in China. However, at present, externally threaded pyrotechnic products are generally tightened manually one by one. Usually, torque wrenches and other manual assembly are used to limit the torque of thread assembly. , The operator is in direct contact with the pyrotechnic product, which poses a great potential safety hazard. And tools such as torque wrenches, when assembling multiple stations, because they are assembled one at a time, not only the same operation is repeated, but a single action can easily lead to operational fatigue and low production efficiency; and there are differences in the assembly effects of d...
