Assembling mechanism for sealing ring of igniter base of gas generator

Abstract

The invention relates to the technical field of assembling of gas generators, and discloses an assembling mechanism for a sealing ring of an igniter base of a gas generator. The assembling mechanism for the sealing ring of the igniter base of the gas generator comprises a base plate. A positioning base is arranged at one end of the base plate. A positioning cavity is formed in the center of the top surface of the positioning base. A sealing ring feeding guide rail is arranged at the other end of the base plate. A vibrating tray is arranged at the outer end of the sealing ring feeding guide rail. A horizontal movement mechanism is arranged above the sealing ring feeding guide rail. A horizontal connecting plate is arranged at the head of the horizontal movement mechanism. A lifting air cylinder is arranged on the upper side of the connecting plate. A connecting base is arranged at the shaft end of the lifting air cylinder. A rotary air cylinder is arranged in the connecting base. A U-shaped support which is open downwards is connected to the shaft end of the rotary air cylinder. The center of the upper end of the U-shaped support is connected with the rotary air cylinder. A sealing ring suction cup is arranged at one end of the U-shaped support. A sealing ring detection head is arranged at the other end of the U-shaped support. According to the assembling mechanism for the sealing ring of the igniter base of the gas generator, the sealing ring in the igniter base can be detected, so that mounting omission of the sealing ring or mounting of redundant sealing rings is effectively prevented, and defective products are prevented in the later stage.

Description

technical field [0001] The invention relates to the technical field of gas generator assembly, in particular to an assembly mechanism of a gas generator ignition seat seal ring. Background technique [0002] The igniter is an important part in the gas generator. When the car collides, the igniter plays an ignition role, and the igniter is installed in the igniter seat. In the actual assembly, first weld the ignition seat on the upper shell of the gas generator, then put the sealing ring into the ignition seat (the outer side of the upper end of the ignition seat is a tapered surface), and finally install the ignition device and pass The pressure riveting makes the conical surface of the ignition tool seat be pressed to form a ring-shaped convex eaves limit. At present, after the sealing ring is sucked by the suction cup, the manipulator puts the sealing ring into the ignition seat. Since the sealing ring is elastic and has a certain degree of cohesiveness, the suction cup m...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem of missing or multiple sealing rings in the ignition seat in the prior art, the present invention provides a sealing ring that can detect the sealing ring in the ignition seat after feeding, so as to effectively prevent the sealing ring from Missing or over-installed igniter seat sealing ring assembly mechanism
