Cabin 1 is detachably connected, and the open end side of cabin 1 is fixedly installed with portal frame 3, and hatch door guiding device is mounted on the portal frame
On 3, the hatch door 2 is mounted on portal frame 3 by the hatch door guiding device, and hatch door 2 can be by hatch door guiding device at gantry
Translation in perpendicular locating for frame 3, the hoistable platform are arranged in the front of the open end of cabin 1 and are located at portal frame 3
The other side, the monitor station 4 for placing laser cutting device 19 to be detected is equipped in the cabin 1, is also equipped in cabin 1
It the gas ducting 6 that is connect with air charging system, the pump-line being connect with vacuum evacuation device and is connect with gas leak detection device
Sensor 7 passes through pumping after laser cutting device 19 to be detected is placed on monitor station 4 and hatch door 2 is closed locking first
Vacuum plant and pump-line vacuumize closed cabin 1, are then swashed by air charging system and gas ducting 6 to be detected
Pour high-pressure inert gas in light cutting equipment 19, if laser cutting 19 to be detected it is closed it is good if do not have inert gas from
Space in laser cutting device 19 internal leakage to cabin 1, and then sensor 7 will not then detect inert gas, sense on the contrary
Device 7 can then be detected from 19 internal leakage of laser cutting device to the inert gas in cabin 1, and then gas leak detection device makes phase
The flashing of the feedback answered, such as alarm lamp or alarm sound are sounded；Control cabinet is mainly taken out air charging system with control, is vacuumized
Space in cabin 1 is vacuumized by vacuum evacuation device after the specific works of device and reference leakage device, such as the closing of hatch door 2,
Specifically being evacuated down to great vacuum degree is configured by control cabinet, when being inflated by air charging system, to laser
Be filled in cutting equipment 19 inert gas in high-pressure inert gas and laser cutting device 19 pressure it is specific it is much be also by
Control cabinet is configured, and the pressure for the inert gas that the laser cutting 19 of different model is filled in specific works is different, therefore
In order to which the air-leakage test for enabling the invention to be enough in the more category laser cuttings 19 of polytypic is particularly important.
