The gas generator ignition pin assembly height detection device and detection method thereof of the present invention relate to the field of gas generator ignition pin assembly height detection technology, and detect whether the distance between the ignition pin needle of the gas generator and the opening edge of the ignition connection hole of the gas generator is qualified. Including the frame, edge full pressure prompter, hydraulic sealing box, qualified prompter, normally open relay switch and normally closed relay switch, the control end of the normally open relay switch is connected in parallel with the control end of the normally closed relay switch. The control end circuit of the relay switch; the first-level series switch of the needle head, the first-level series switch of the edge port, and the first-level series switch of the pressure plate are connected in series in turn to form the No. 1 detection switch, which is then connected in series to the power circuit of the control end circuit of the relay switch On; the controlled end of the normally open relay switch is connected in series to the power circuit of the qualified reminder; the controlled end of the normally closed relay switch is connected in series to the power circuit of the hydraulic input device.
Description
technical field [0001] The invention relates to the technical field of detecting the assembly height of an ignition pin of a gas generator, in particular to a device for detecting the assembly height of an ignition pin of a gas generator and a detection method thereof. Background technique [0002] Whether the distance between the needle of the ignition needle of the gas generator and the opening edge of the ignition connection hole is qualified is related to whether the ignition of the gas generator is successful. If the distance between the needle of the ignition needle and the edge of the opening of the ignition connection hole is greater than the set distance, the ignition needle will not be inserted into the power socket on the ignition connection plug, so that the ignition needle is not connected to the power supply, resulting in There is a situation of misfire when igniting. If the distance between the needle of the ignition needle and the edge of the opening of the ...
