Gas generator igniter seat sealing ring assemble mechanism
Technical field
The present invention relates to gas generator mounting technology field more particularly to a kind of gas generator igniter seat sealing rings
Assemble mechanism.
Background technology
Igniter is component important in gas generator, and when automobile collides, igniter plays ignition action, point
Fire tool is mounted in igniter seat.In actual assembled, first igniter seat is welded on the upper shell of gas generator, in handle
Sealing ring is packed into igniter seat(It is the conical surface on the outside of the upper end of igniter seat), finally it is packed into igniter and makes invocation point by pressing
The conical surface of fire tool seat is pressurized to form the limit of convex annular eaves.Usually all it is that manipulator handle seals after sealing ring is sucked by sucker at present
Circle is packed into igniter seat, and since sealing ring has elasticity, and sealing ring also has certain caking property, therefore sucker picks up
Two sealing rings may be picked up when sealing ring simultaneously, it is also possible to sealing ring can not be picked up, may result in igniting in this way
Have and lacks sealing ring in seat or there are two above sealing ring, lack close after load point fire tool seat in the igniter seat of sealing ring
Envelope property cannot be satisfied requirement, cause defective products long-living, the assembly of follow-up igniter can be influenced more by having filled sealing ring then, cause to light a fire
The assembly height having with igniter seat is undesirable, and there is no sealing rings to examine on igniter seat sealing ring assemble mechanism at present
Mechanism is surveyed, therefore is easy to cause neglected loading sealing ring in igniter seat or fills sealing ring more.
Invention content
The present invention provides one to overcome the problems, such as neglected loading or more dress sealing rings in igniter seat in the prior art
After kind sealing ring charging, the sealing ring in igniter seat can be detected, to effectively prevent sealing ring neglected loading or more dresses
Igniter seat sealing ring assemble mechanism.
To achieve the goals above, the present invention adopts the following technical scheme that:
One end of a kind of gas generator igniter seat sealing ring assemble mechanism, including bottom plate, the bottom plate is equipped with positioning
