DETAILED DESCRIPTION

[0025] like Figure 1-2 As shown, a radiator leak detection device includes a base 1 and a placement rack 2. The placement rack 2 is arranged on the top of the base 1, and there are two groups of them. It also includes a linear guide rail 3, a slider 4, a positioning assembly and a support assembly. The linear guide rail 3 is fixedly installed on the top of the base 1, and the slider 4 is slidably set on the linear guide rail 3. One group of placement racks 2 is fixedly connected to the top of the base 1, and the other group of placement racks 2 is fixedly connected to the top of the slider 4.

[0026] The clamping and positioning of the radiator before detection is completed by the positioning component, and the middle position of the radiator and the bottom of a group of placement racks 2 are auxiliary supported by the support component.

[0027] like Figure 1-4 As shown, in order to position the radiator and facilitate air tightness testing, the positioning assembly includes a cylinder 5, a pressure plate 6 and a limit column 7. The cylinder 5 vertically passes through the top of the placement rack 2 and is slidably connected to it. The pressure plate 6 is fixedly connected to the free end of the cylinder 5. The limit column 7 is fixedly connected to the outer wall of the pressure plate 6. A limit hole 8 is provided on one side of the placement rack 2. The limit hole 8 is arranged in a vertical strip shape, and one end of the limit column 7 extends to the limit hole 8.

[0028] like Figure 1-4 As shown, in order to provide auxiliary support for the radiator, the support assembly includes a telescopic rod 9, a support plate 10 and a spring 11. The telescopic rod 9 is fixedly connected to the top of the base 1 and is symmetrically distributed front to back. The support plate 10 is fixedly connected to the upper end of the telescopic rod 9. The spring 11 is sleeved outside the telescopic rod 9, and its two ends are fixedly connected to the base 1 and the support plate 10. A bottom groove 14 is provided on the top of the base 1, and is symmetrically distributed front to back. A group of placement racks 2 are provided with symmetrically distributed bottom rods 15 at the bottom, and a ball bearing 16 is provided at the bottom of the bottom rod 15, and is provided inside the bottom groove 14.

[0029] In order to protect the radiator, a sponge pad 12 is provided at the bottom of the pressing plate 6 and a rubber pad 13 is provided on the placement frame 2.

[0030] In order to prevent the movable placement rack 2 from affecting the placed radiator, the height of the top of the support plate 10 is higher than the top surface height of the rubber pad 13 .

During the sliding process, the ball 16 at the bottom of the bottom rod 15 rolls inside the bottom groove 14 to provide auxiliary support for the placement rack 2. The radiator can be pressed and positioned by controlling the left side cylinder 5 to extend. At this time, the support plate 10 will be subjected to force to apply pressure to the spring 11, and the spring 11 contracts to cause the telescopic rod 9 to contract. The output end of the air pump 17 is connected to the inlet of the radiator, and the outlet of the radiator is connected to the barometer. After injecting air into the radiator, let it stand for a while, and observe the value of the barometer to detect its air tightness.
