Description

Technical Field

[0001] The invention relates to the technical field of air tightness detection, and in particular to an air tightness detection device and a detection method for a rubber seal for a water pump. Background Art

[0002] Most of the existing rubber seals are sealing ring structures. After the sealing ring is produced, its own air tightness needs to be tested to ensure that its air tightness meets the use requirements. However, the existing air tightness detection device cannot detect rubber seals of different specifications, and it is also not convenient to observe the sealing of the rubber seal. An air tightness detection device for rubber seals with application number CN202120320058.X includes a first box body, an electric hydraulic lift and a test sample, which is convenient for fixing the rubber seal and detecting rubber seals of different specifications, and is also convenient for observing the sealing of the rubber seal.

[0003] Although the device has the above advantages, it still has the following defects in actual use:

[0004] 1) When the device is used, the rubber seal needs to be placed on the test sample for testing. When testing seals of different specifications, multiple adapted test samples are required, which increases the test cost on the one hand, and requires repeated installation and removal of the seal on the test sample on the other hand, resulting in reduced actual efficiency;

[0005] 2) The seal is set on the test sample for testing, for example, the seal is set between two pipes for testing, which makes it impossible to intuitively test the airtightness and the test results vary greatly.

[0006] Therefore, it is necessary to solve the shortcomings that still exist in the existing devices. Summary of the invention

10. A method for detecting an airtightness detection device for a rubber seal for a water pump, using an airtightness detection device for a rubber seal for a water pump as claimed in any one of claims 1 to 9, characterized in that: The specific steps include: Step 1: The sealing ring to be tested is mounted on the surface of the conical seat (4), and then the linear motor (8) slides along the slide rail (7), and the conical seat (4) drives the sealing ring to move synchronously through the connecting rod (9), and the sealing ring enters the inner ring of the missing ring (51) to be aligned with the scanner (53), and then the driving motor (55) drives the missing ring (51) to rotate through the gear column (54), so that the regulating cylinder (52) drives the scanner (53) to rotate accordingly, so as to perform an overall scanning image of the surface of the sealing ring, and determine whether its appearance has defects through the imaging; Step 2: After the sealing ring is scanned and imaged, the linear motor (8) drives it to reset in the reverse direction, and then drives it to move forward. During the process of moving forward again, the ends of the telescopic cylinders (11) on both sides extend out, driving the two arc strips (10) to close and sleeve on the outside of the conical seat (4). The conical seat (4) abuts against the rubber strips (14) on both sides along with the movement, and the sealing ring is pushed to move on the surface of the conical seat (4) through the squeezed rubber strips (14), so that the sealing ring expands and deforms again, and then step 1 is repeated to scan and detect the surface of the sealing ring again. Step 3: The linear motor (8) drives the cone seat (4) to continue to move, so that the cone seat (4) drives the sealing ring to enter the cone sleeve (3), so that the thickness of the sealing ring is the same as the distance between the two. Then the fan (64) works to absorb external air through the air hole (65) and blows air into the cone sleeve (3). By monitoring whether air is blown out from the other side of the cone sleeve (3), the air tightness of the sealing ring is detected.
