It usually includes an air pump, etc. By testing the sealing performance of automobile parts, such as motor accessories, the sealing detection device can ensure that the parts have good sealing performance to meet the use requirements of automobiles.

[0003] When detecting the sealing of automobile motor accessories, it is necessary to manually lift the motor accessories into the detection device and then detect them through an air pump. After detection, the motor accessories need to be manually lifted out of the device, which is rather troublesome. Moreover, the motor accessories are relatively heavy, and it is easy to bump when manually moving the motor accessories, resulting in damage to the motor accessories and injuries to the workers, increasing the detection cost and affecting the work efficiency. Summary of the Invention

[0010] As a further description of the above technical solution:

[0011] A second chute is provided inside the second horizontal guide rail, and the position of the first chute corresponds to the position of the second chute.

[0012] As a further description of the above technical solution:

[0013] A vertical chute is fixedly connected to the front surface of the base, and the side end of the second horizontal guide rail is located inside the vertical chute.

At this time, the lower die is located inside the fixed ring. The electric telescopic rod drives the fixed ring to move horizontally, and the fixed ring drives the lower die to move horizontally along the first horizontal guide rail until the end. Then the hydraulic cylinder drives the movable plate to move downward, and the movable plate drives the upper die to move downward until the upper die and the lower die are hermetically fitted. Then the air pump pumps air into the upper die and the lower die for a certain period of time, and then observes the value of the pressure gauge. After a certain period of time, observes the value of the pressure gauge again, and compares the two values. If the values are similar, the sealing performance of the motor accessory is better, and vice versa. After the detection is completed, the hydraulic cylinder drives the movable plate to move upward along the limiting rod. The movable plate simultaneously drives the second horizontal guide rail to move upward along the vertical chute and the upper die to move upward until the second horizontal guide rail is connected to the first horizontal guide rail and stops moving upward. Then the electric telescopic rod drives the fixed ring to move horizontally, and the fixed ring drives the lower die to move horizontally along the first horizontal guide rail until the slider contacts the limiting block at one end of the second horizontal guide rail and stops. Then the hydraulic cylinder drives the movable plate to move downward, and the movable plate drives the second horizontal guide rail to move downward until the second horizontal guide rail is located at the bottom end of the vertical chute. Compared with the prior art where it is more troublesome to manually handle automobile motor accessories, with higher labor costs and lower detection efficiency, this sealing detection device for automobile motor accessories reduces labor costs and improves detection efficiency.

Then, the two values are compared. If the values are similar, the sealing performance of the motor accessory is good. On the contrary, if the difference between the two measured values is large, it indicates that the gas inside the motor accessory leaks into the cavity, and the sealing performance of the motor accessory is insufficient.
