[0018] A fixing bracket is used to fix the plastic vacuum cylinder to the drain filter screen to prevent displacement during the cleaning process;

[0019] An air gun, used for cleaning the surface of a plastic vacuum cylinder.

[0020] Furthermore, the main frame is also equipped with: a counter for recording the total number of tests and the number of defective products; and an alarm light that flashes when the pressure sensor detects insufficient pressure.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Applicant's design Figure 1-2 The tooling shown includes a frame body 1 for underwater airtightness testing of a plastic vacuum cylinder 16, which is divided into two areas: a test area and a cleaning area. The frame body 1 is also equipped with: an airtightness testing component, which is located in the test area and is used to conduct underwater simulation tests on the sealing performance of the plastic vacuum cylinder 16; and a cleaning component, which is located in the cleaning area and is used to clean the water stains on the surface of the plastic vacuum cylinder 16 after the test.

[0028] The tooling for underwater airtightness testing of plastic vacuum cylinders in this embodiment further includes the following airtightness testing components: a water tank 2, which is mounted on the frame body 1 and used for underwater testing of the plastic vacuum cylinder 16; an inlet valve 3 on the water tank 2 and a drain valve 4 at the bottom; a cylinder 5, which is mounted above the water tank 2 via a bracket 6; a product test frame 7, which is mounted on the cylinder 5 and moves up and down driven by the cylinder 5; the product test frame 7 is used to place the plastic vacuum cylinder to be tested; an inlet valve 8, which is connected to the plastic vacuum cylinder 16 to be tested; after the plastic vacuum cylinder 16 is completely submerged in the water tank 2, it begins to inflate; after the required air pressure is reached, the air pressure inside the cylinder stabilizes under the required air pressure for a specified time before automatically venting; and a real-time pressure monitor 9, which is used to monitor whether the air pressure inside the plastic vacuum cylinder 16 reaches the specified value during the test.

[0029] The tooling for underwater airtightness testing of plastic vacuum cylinders in this embodiment further includes a cleaning component comprising: a water stain collection box 10 for collecting water stains from the surface of the cleaned qualified product, with a drain valve 4 at the bottom of the water stain collection box 10; a drain filter 11 mounted on the water stain collection box 10 for filtering water; a fixing bracket 12 for fixing the plastic vacuum cylinder 16 on the drain filter 11 to prevent displacement during cleaning; and an air gun 13 for cleaning the surface of the plastic vacuum cylinder 16.

[0030] Furthermore, the tooling for underwater airtightness testing of plastic vacuum cylinders in this embodiment is further provided with the following on the frame body 1: a counter 14 for recording the total number of tests and the number of defective products; and an alarm light 15 that flashes when the pressure sensor detects insufficient pressure.

[0031] Working principle of the tooling:

[0032] 1. Before testing, add a certain amount of clean water to water tank 2. The water tank has maximum and minimum markings inside.

[0033] 2. Power on the equipment. Set the inflation pressure, inflation time, underwater test time, and automatic deflation time on the equipment control panel.

[0034] 3. Insert a soft plug with an air inlet tube into the interface of the product to be tested and place it in the product test frame 7. The frame is made of aluminum alloy, closed on all sides, and has a door that can be opened and closed. Open the door to put in the product, and then close the door. The door has a hinge to prevent it from being opened during the process of the device being submerged in water, so that the product to be tested cannot be submerged in the water due to the buoyancy of the water.

[0035] 4. After closing the door, press the equipment start button. Cylinder 5 begins to descend, and the test product enters the water. Air inlet valve 8 fills the plastic vacuum cylinder 16 with air until the required pressure is reached. Under the required pressure, the internal pressure stabilizes for a specified time before automatic venting begins. Once automatic venting is complete, cylinder 5 rises, pulling the plastic vacuum cylinder 16 out of the water. Counter 14 records the readings. If the test product leaks, and the internal pressure fails to reach the set pressure, alarm light 15 will sound, and the number of defective products will be recorded. During the test, the internal pressure changes can be observed through real-time pressure data transmitted by the pressure sensor.

[0036] 5. After the product test is completed, open the door of the product test frame 7, take out the plastic vacuum cylinder 16, remove the soft plug inserted into the air inlet, put the product into the cleaning area and clip it onto the fixing frame 12, and use the air gun 13 to remove the water adhering to the product to prevent contamination of the product surface and rusting of the metal inserts on the product.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
