The principle of the scheme is as follows: the gas tightness part is placed on the positioning seat, the gas tightness part is covered by the detection box, the positioning block is moved, and the positioning block is fixed by the limiting bolt, so that the detection box is fixed. And starting the air cylinder to enable the piston to move downwards to drive the movable rod to move, so that the pressing plate is driven to move downwards. The second magnet attracts the first magnet, so that the pressing plate is pressed on the detection box. When the pressing plate is pressed on the detection box, gas with certain pressure is filled into the detection box, and then the air pressure in the detection box is detected by using the air tightness detector. And checking whether the air pressure is reduced or not, wherein if the air pressure is reduced, the air tightness of the part is not good, and if the air pressure is not changed, the air tightness of the part is good. After the detection is finished, the air cylinder is started to drive the pressing plate to move upwards, and the detection box is opened to take out the air tightness part.
The scheme has the beneficial effects that: through setting up first magnet and second magnet and replacing the guide post, make the holddown plate direction can not squint, reduce the holddown plate wearing and tearing, attract mutually through first magnet and second magnet, make the holddown plate compress tightly the detection case, reinforcing detection case's leakproofness. The compacting plate reciprocates the in-process, and the wearing and tearing of magnet are greater than the compacting plate, can in time change the gas tightness through the degree of wear of judging magnet and detect the frock, make the testing result more accurate. Through removing the locating piece position, fixed not equidimension detection case to detect the gas tightness part of equidimension not.
Further, the surface of the pressing plate is provided with a rubber sealing ring. Reduce the damage of the pressure plate and enhance the sealing performance of the detection box.
Furthermore, the positioning block is fixedly connected with the side wall of the positioning seat through a spring. The positioning block is convenient to move.
Further, a gas alarm is arranged on the detection box. When leakage occurs, a sound is given out to prompt a worker to overhaul the equipment.
Further, the second magnet is an electromagnet. When the pressing plate presses the detection box tightly, the second magnet is electrified and attracts the first magnet. When the hold-down plate needs to be removed, the second magnet is de-energized and no longer attracts the first magnet. When the power is on, the second magnet attracts the first magnet, so that the direction of the pressing plate cannot deviate, and the pressing plate tightly presses the detection box; when the power is off, the second magnet does not attract the first magnet, and the pressing plate is easy to remove.
Furthermore, the rack is provided with rollers. Conveniently remove gas tightness and detect frock.
