[0028] The new type of pneumatic mechanism automobile part air tightness detection device has the fixed mold arranged on the base frame, the fixed product base 7 is made in imitation of the product structure and has the sealing rubber ring added around the bottom, the lifting cylinder 1 is connected with the sealing tool 9, drives the sealing tool 9 to make the up-down compression sealing movement above the fixed mold, then the side plug cylinder 10 works to make the side sealing tool 9 close the side opening hole, then a series of steps of inflating, pressure maintaining and leakage of the product are completed, and the product air tightness is qualified. The automobile part air tightness test tool equipment structure is simple, the fixed mold and the sealing tool 9 special for the automobile part are arranged, the existing air tightness tester can be used for testing, the operation is simplified, the air tightness detection requirement of the automobile shell product 6 is efficiently detected, the air tightness of each automobile product to be detected is detected one by one, the qualified products are ensured to be shipped, the products can be normally used and the molds can be interchanged when put into use, and the air tightness test device is in a semi-automatic mode, compared with the pure manual test, the effect is high, the structure is simple, the operation is convenient, and great cost is saved.
[0029] The first step is product placement: first, the automobile shell product 6 is placed on the fixed product base 7, the adaptive shape of the fixed product base 7 is used to realize the preliminary positioning of the product, and the subsequent sealing and detection operations are prepared.
[0030] The second step is sealing preparation: the lifting cylinder 1 is started, the lower mold pressing block 5 is driven to move towards the automobile shell product 6, the lower mold pressing block 5 reaches the appropriate position, a certain pre-pressure is applied to the product, and the further sealing operation of the sealing tool 9 is well prepared.
[0031] The third step is sealing operation: the lower mold cylinder 4 drives the plurality of sealing tools 9 to move towards the automobile shell product 6, the sealing tools 9 are tightly attached to the corresponding parts of the product, the parts of the product that need to be sealed are sealed, a relatively closed space is formed, and the subsequent detection gas is filled to detect the air tightness.
[0032] The fourth step is plug operation (if necessary): the plug cylinder 10 pushes the related parts of the automobile shell product 6 or plugs the specific opening according to the detection requirement, ensures that the flow path of the detection gas in the product inside meets the detection setting, and further improves the sealing condition of the detection.
[0033] The fifth step is air tightness detection: the detection gas (such as compressed air) with a certain pressure is filled into the sealed automobile shell product 6, then the detection device monitors the change of the gas pressure, flow and other related parameters with time, whether the product has gas leakage is judged according to the set standard, that is, whether the air tightness of the product is qualified is judged.
