[0020] In this utility model, to solve the problem of insufficient automation and low efficiency in existing testing equipment, the following technical solution is adopted: The support component includes guide pillars 6, which are vertically installed and fixed around the top surface of the base plate 2. A top plate 5 is fixedly connected to the top of the guide pillars 6. Multiple oil storage grooves are opened on the outer side of the guide pillars 6. A pressure plate 4 is sleeved on the outer side of the guide pillars 6. Limiting pillars 7 are provided below the bottom surface of the pressure plate 4.

A clamping seat 3 is installed and fixed in the middle of the top surface of the base plate 2, and positioning blocks 8 are fixedly connected around the top surface of the base plate 2. The testing component includes a hydraulic cylinder 9, which is installed and fixed in the middle of the top surface of the top plate 5. The bottom end of the hydraulic cylinder 9 penetrates the top plate 5 and is fixedly connected to the pressure plate 4. A pressure gauge 13 is installed and fixed on the front end of the top surface of the top plate 5. A battery cover 10 is provided below the pressure plate 4. The positioning block 8 is installed and fixed on the clamping base 3. Cylinders 11 are provided on both the left and right sides of the clamping base 3. The cylinders 11 are installed and fixed on both sides of the top surface of the base plate 2. Side plugs 12 are fixed to the telescopic ends of the opposite sides of the cylinders 11. Multiple vertical plugs 14 are fixed at equal intervals in the middle of the bottom surface of the pressure plate 4.

[0021] Working Principle: When using this utility model, firstly, power is supplied to all electrical equipment. Then, the battery cover 10 is aligned with the positioning blocks 8 fixed around the top surface of the clamping base 3, thereby fixing the battery cover 10 onto the clamping base 3. Next, the cylinders 11 fixed on both sides of the top surface of the base plate 2 are activated, causing their telescopic ends to move the side plugs 12, clamping the battery cover 10 while blocking the through holes on the side of the battery cover 10. Then, the hydraulic cylinder 9 fixed in the middle of the top surface of the top plate 5 is activated, causing its bottom end to penetrate the top plate 5 and drive the pressure plate 4 sleeved on the outer side of the guide post 6 to descend until multiple vertical plugs 14 fixed at equal intervals on the bottom surface of the pressure plate 4 are inserted into the through holes on the top surface of the battery cover 10. At this time, the rubber rings 15 sleeved on the lower end of the outer side of the vertical plugs 14 are completely sealed. The battery cover 10 has an internal cavity. Air is introduced into the cavity through an air inlet 16 horizontally opened on the front of one of the outer sides of the vertical plug 14. This air inlet 16 passes through the interior of the vertical plug 14 and connects downward to the punching port 17. After inflation, it can provide pressure data to the pressure gauge 13 fixed on the front end of the top plate 5. After a period of time, the change in the pressure gauge 13 is checked to determine the airtightness of the battery cover 10. After the test is completed, the operation is reversed. First, the hydraulic cylinder 9 drives the pressure plate 4 to rise, and the vertical plug 14 is disengaged from the battery cover 10. Then, the cylinder 11 drives the side plug 12 to reset, releasing the battery cover 10. Then, the battery cover 10 is removed, and the same test operation is performed on the next battery cover until all tests are completed. Finally, the device is turned off and the power is cut off.
