There is a slide rail, and the symmetrical two sides of the movable seat 3 are respectively slidably connected in the slide groove of the slide rail. Through the setting of the linear module 2, the two movable seats 3 can be synchronously driven to move in position. When the workpiece on one of the movable seats 3 is being inspected, the other movable seat 3 can be loaded and unloaded, which can effectively improve the convenience of loading and unloading, and also improve the inspection efficiency. Since multiple mounting plates 4 are set on each movable seat 3, each mounting plate 4 can be installed with a workpiece, and multiple inner partitions 18 are fixedly connected to the inner wall of the inspection cover 8, so that the interior of the inspection cover 8 has multiple inspection cavities, and each inspection cavity corresponds to a workpiece.

The pressure sensors 9 can be used to monitor the air pressure value inside each detection cavity in real time, and transmit the monitoring data to the pressure switch 10. The pressure switch 10 analyzes and compares the received data. When the monitored data exceeds the set data, the working circuit of the corresponding indicator light 11 is closed, and the indicator light 11 lights up. At this time, the staff can easily know that the workpiece is leaking, which is convenient for the staff to eliminate unqualified products.

During the test, all the second solenoid valves 17 can be closed first, and all the first solenoid valves 15 can be opened. Then the vacuum pump 14 can be started. Under the connection of the connecting seat 13, the vacuum pump 14 can effectively extract the air inside the entire detection cover 8, so that each detection cavity is in a vacuum state. Then all the first solenoid valves 15 are closed, and then all the second solenoid valves 17 are opened. At this time, each detection cavity can perform detection operations independently, ensuring that the synchronous detection of multiple workpieces can be carried out effectively without affecting each other.

[0028] Working principle: When in use, first install the device at the specified position, then select the corresponding connecting terminal 5 according to the workpiece to be tested, and then install the connecting terminal 5 on the mounting plate 4, and then install the workpiece at one end of the connecting terminal 5. After installation, start the linear module 2 so that the movable seat 3 with the workpiece installed is directly below the detection cover 8, and then extend the hydraulic rod 7 so that the detection cover 8 can be buckled on the outside of the movable seat 3. Due to the setting of the internal partition 18, each workpiece is now in an independent detection cavity, and the detection operation can be performed at this time. First close all the second solenoid valves 17, open all the first solenoid valves 15, and then start the vacuum pump 14. Under the connection of the connecting seat 13, the vacuum pump 14 can effectively extract the air inside the entire detection cover 8, so that each detection cavity is in a vacuum state, and then close all the first Solenoid valve 15, then open all the second solenoid valves 17. At this time, each detection chamber can perform detection operations independently. After vacuuming, the pressure sensor 9 is used to monitor the air pressure value inside each detection chamber in real time, and the monitoring data is transmitted to the pressure switch 10. The pressure switch 10 analyzes and compares the received data. When the monitored data exceeds the set data, the working circuit of the corresponding indicator light 11 is closed, and the indicator light 11 lights up. At this time, the staff can easily know that the workpiece is leaking, which is convenient for the staff to eliminate unqualified products. During the workpiece detection process, the staff can install multiple workpieces to be tested on another movable seat 3 to improve the test efficiency. After the detection is completed, the third solenoid valve and the first solenoid valve 15 are opened to restore the internal air pressure of the detection cover 8, which is convenient for the detection cover 8 to open, and the next round of test operations is carried out in the same way.
