The outer diameter of the first columnar part is smaller than that of the second columnar part, and the first columnar part is connected to the top of the second columnar part, and the first columnar part and the second columnar part are transitioned by a truncated cone part. A hexagonal annular convex part is arranged on the outer peripheral wall of the lower part of the second columnar part, and a bottom hole is arranged at the bottom end of the second columnar part. The automobile water temperature sensing component has high requirements for air tightness during operation, but due to the existence of its bottom hole, the wall at the second columnar part is thinner, and there may be a problem of air leakage.

Therefore, it is necessary to design an air tightness detection device for automobile water temperature sensing components to prevent leaking unqualified products from entering the market.

A plurality of detection holes 7 for placing automobile water temperature sensing components are provided at the top of the detection platform 3. An air hole 8 is provided at the bottom of each detection hole 7. The air hole 8 is connected to a ventilation device. The air hole 8 forms an opening 9 at the bottom of the detection hole 7. The inner diameter of the opening 9 is smaller than the inner diameter of the bottom hole of the automobile water temperature sensing component. The detection holes 7 in this embodiment are distributed in an array at the top of the detection platform 3, with a total of two rows and six columns, wherein, as Figure 3As shown, the air holes 8 corresponding to the two detection holes 7 in the same row are connected to each other and form a connecting hole on the side wall of the detection platform 3, that is, a total of six connecting holes, and the six connecting holes are connected to the same ventilation device (not shown in the figure); in addition, as Figure 3 As shown, each detection hole 7 is connected to a sealing ring 14, the inner diameter of the sealing ring 14 is larger than the inner diameter of the opening 9, the sealing ring 14 and the detection hole 7 and the opening 9 are coaxially arranged, when the automobile water temperature sensing component is placed in the detection hole 7, the bottom end of the automobile water temperature sensing component abuts against the top end of the sealing ring 14, and the bottom end of the automobile water temperature sensing component abuts against the sealing ring 14 along the circumferential direction. Assuming that the air tightness of the automobile water temperature sensing component is good, the bottom hole of the automobile water temperature sensing component and the air hole 8 form a closed inner cavity.
[0020] like Figure 1 and Figure 2 As shown, the connecting seat 4 is connected to the detection platform 3 and is located above the detection platform 3, the second cylinder 5 is connected to the connecting seat 4, the piston rod of the second cylinder 5 is vertically arranged and connected to the top of the pressure block 6, the piston rod of the second cylinder 5 is downwardly arranged, and the pressure block 6 is located below the connecting seat 4, the first cylinder 2 drives the detection platform 3 to move and makes the detection platform 3 located on the water surface or under the water surface, and the second cylinder 5 drives the pressure block 6 to press against the automobile water temperature sensing component placed in the detection hole 7.
[0021] like Figure 1 and Figure 2 As shown, two left and right first guide columns 10 are connected to the top of the base 1, and the detection platform 3 is slidably connected to the two first guide columns 10; further, the tops of the two first guide columns 10 are connected by a connecting plate 11, and because the second cylinder 5 will move up and down with the detection platform 3, an avoidance hole 12 is provided on the connecting plate 11, and the second cylinder 5 is located in the avoidance hole 12, and the second cylinder 5 can pass through the avoidance hole 12.

[0023] like Figure 4The figure shows the structure diagram of the automobile water temperature sensing component. The air tightness test is carried out in water. The first cylinder 2 drives the detection platform 3 so that the detection platform 3 is located on the water surface. Then the automobile water temperature sensing component is placed in each detection hole 7. After that, the second cylinder 5 drives the pressing block 6 to press down and press against the automobile water temperature sensing component, so that the bottom hole of the automobile water temperature sensing component and the air hole 8 form a closed inner cavity. Then the first cylinder 2 drives the detection platform 3 to descend below the water surface. Since the detection platform 3 is connected to the connecting seat 4, the connecting seat 4 and the second cylinder 5 are driven to descend synchronously when the detection platform 3 descends, so that The pressing block 6 is kept in a state of pressing the automobile water temperature sensing component.
