[0023] See also Figure 1-3 The present embodiment provides a double-station airtightness detection tool for a shell, including a base 1, a protective cover 2 is fixedly installed on the top of the base 1, and cylinders 3 are fixedly installed at both ends of the top of the protective cover 2. Feeding plates 4 are symmetrically installed at both ends of the top of the base 1, and sealing grooves 41 are symmetrically opened at both ends of the top of the feeding plate 4. A mold table 5 is installed on the inner side of the sealing groove 41. The size of the mold table 5 is designed according to the size of the shell to be detected. A Z-shaped plate 8 is installed on the top of the base 1, which is located on the inner side of the protective cover 2. A telescopic rod 9 is fixedly installed on the top of one end of the Z-shaped plate 8. The Z-shaped plate 8 is located directly above the feeding plate 4, and the other end of the Z-shaped plate 8 is fixedly connected to one end of the top rod of the cylinder 3. When inspecting the shell, first separate the shell body and shell cover, and insert one end of the shell body and shell cover into the inner side of two sealing grooves 41 at the top of a loading plate 4 respectively. Note that the top of the cover plate is close to the lower end of the Z-shaped plate 8. At this time, start the cylinder 3, and the cylinder 3 moves the Z-shaped plate 8 downward, so that the two ends of the bottom of the Z-shaped plate 8 respectively squeeze the shell body and shell cover of the shell. At this time, the shell body and shell cover can be tested for air tightness, and there is no need to test the shell body and shell cover separately in batches, thereby somewhat improving the air tightness detection efficiency of the shell.

[0024] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, a pressurizing device 10 is installed at one end of the base 1, and an air supply pipe 11 is connected to the bottom of one side of the pressurizing device 10 and inserted into the interior of the base 1. A control valve 12 is installed at the center of the outer ring surface of the air supply pipe 11, and two connecting pipes 13 are installed on both sides of the top of the air supply pipe 11 located on the control valve 12. The connecting pipes 13 are respectively connected to the air inlet ring 6 on the top of the mold table 5. The pressurizing device 10 has a built-in pressurizing pump. The pressurizing device 10 exhausts air through the air supply pipe 11 and enters the top of each mold table 5 through the connecting pipe 13. At this time, the shell body and shell cover pressed on the feeder 4 can be inflated to detect the air tightness.

[0025] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the pressurizing device 10 is provided with a touch screen control panel, and the pressurizing device 10 is electrically connected to the pressure sensor 7, the cylinder 3 and the control valve 12. After the interior of the shell is pressurized, the pressure change is detected by the pressure sensor 7, and the pressure change value is observed through the control panel on the pressurizing device 10 to judge the airtightness of the shell.

[0026] In this embodiment, if Figure 1 and Figure 2 As shown, the height difference between the two ends of the bottom of the Z-shaped plate 8 is the same as the height difference between the top of the shell body and the shell cover being tested, and one end of the telescopic rod 9 at the top of the Z-shaped plate 8 is fixedly connected to the inner top of the protective cover 2, so that when the Z-shaped plate 8 moves downward, the downward pressure on the shell body and the shell cover is the same, ensuring the sealing of the edges of the shell body and the shell cover.

[0027] Working principle: When the double-station airtightness detection tool of the shell is used, the shell body and the shell cover are first separated, and one end of the shell body and the shell cover are respectively inserted into the inner side of the two sealing grooves 41 at the top of a feeding plate 4. Note that the top of the cover plate is close to the lower end of the Z-shaped plate 8. At this time, the cylinder 3 is started, and the cylinder 3 moves the Z-shaped plate 8 downward. Since the height difference between the two ends of the bottom of the Z-shaped plate 8 is the same as the height difference between the shell body and the top of the shell cover to be tested, when the Z-shaped plate 8 moves downward, the downward pressure on the shell body and the shell cover is the same. At this time, the two ends of the bottom of the Z-shaped plate 8 are respectively The shell body and shell cover of the shell are extruded to ensure the sealing of the edges of the shell body and the shell cover, and then the pressurizing device 10 exhausts air through the air supply pipe 11 and enters the top of each mold table 5 through the connecting pipe 13. At this time, the inside of the shell body and shell cover pressed on the loading plate 4 can be inflated. After the inside of the shell is pressurized, the pressure change is detected by the pressure sensor 7, and the pressure change value is observed through the control panel on the pressurizing device 10 to judge the airtightness of the shell. There is no need to test the shell body and shell cover separately in batches, thereby somewhat improving the airtightness detection efficiency of the shell.

[0028] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation scheme of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
