[0002] The airbag system is a critical component of a vehicle, consisting of an adapter and an igniter. The adapter connects the airbag system to the vehicle's other electrical systems, serving as the system's electrical interface. The adapter has an internal bore that connects the helium chamber to the adapter's outer diameter. In the event of a collision, the adapter and the igniter work together, releasing helium into the adapter. The adapter then uses the inner and outer diameter holes to align and release helium into the airbag, activating the airbag's deployment mechanism. After production, the adapter's inner bore diameter and height must be inspected to ensure proper dimensions.

[0003] The existing detection method generally uses manual inspection. Due to the large number of adapters and high labor intensity, after working for a long time, there is often a risk of missing the inner hole size due to fatigue, which affects the product qualification rate.

The output end of the second cylinder 5 is connected to the slider 7. The gauge plug 8 is arranged on the slider 7. The gauge plug 8 is located above the measuring station 2. The diameter of the gauge plug 8 matches the inner hole diameter of the adapter 9. The length of the gauge plug 8 is greater than the depth of the inner hole of the adapter 9. The slider 7 is driven to rise and fall by the second cylinder 5, and then the gauge plug 8 is driven to rise and fall. The end point of the moving trajectory of the gauge plug 8 is the bottom surface of the inner hole of the adapter 9.
