Multiple clamping components are threaded to both ends of the double-ended screw 18 and the double-ended screw 2 19.

[0031] The clamping assembly includes a clamping seat 20, a clamping plate 21, and a double-ended screw 22. Multiple clamping seats 20 are slidably connected to the workpiece support plate 15.

The double-ended screw 22 is rotatably connected to the inside of the clamping seat 20. The clamping plate 21 is slidably connected to the inside of the clamping seat 20. A screw nut is fixedly connected to the bottom of the clamping plate 21. The double-ended screw 22 is threadedly connected to the screw nut below the clamping plate 21.

[0032] Before testing, the test piece 16 can be adjusted by rotating the first double-ended screw 18 and the second double-ended screw 19 to align the positions of the four clamping components with the four sides of the test piece 16. Then, the third double-ended screw 22 is rotated to move the clamping plates 21 on both sides inward to clamp the four sides of the test piece 16, preventing the test piece 16 from shaking or even falling during long-term air blowing aging tests and vibration tests. This can better simulate the situation of a car instrument panel installed inside a car.

[0033] In this embodiment, a hot air component 2 and an ozone generator 3 are fixedly connected to both sides of the housing 1. The outlet ends of the hot air component 2 and the ozone generator 3 are fixedly connected to the inner wall of the housing 1. The hot air component 2 can continuously blow hot air to test the test piece 16 for aging, and the ozone generator 3 can blow ozone to accelerate the aging of the rubber parts.

[0034] An ultraviolet lamp 4 is fixedly connected to the top of the box 1. The ultraviolet lamp 4 can accelerate aging by ultraviolet irradiation.

[0035] In this embodiment, a workpiece support 14 is fixedly connected below the workpiece support plate 15, a vibration rod 11 is fixedly connected below the workpiece support 14, a vibration bracket 6 is slidably connected below the vibration rod 11, a sliding support plate 5 is fixedly connected below the vibration bracket 6, and the sliding support plate 5 is slidably connected to the bottom of the box 1.

[0037] In this embodiment, a vibration motor 9 is fixedly connected above the sliding plate 5, and a cam 10 is fixedly connected to the power output end of the vibration motor 9. The side wall of the cam 10 is slidably connected to the bottom of the vibration rod 11.

[0038] When the vibration motor 9 is working, it can drive the cam 10 to rotate. The cam 10 protrudes on one side and repeatedly squeezes the vibration rod 11 to rise and fall, thus vibrating the test piece 16.

[0039] In this embodiment: Before testing, the test piece 16 can be adjusted by rotating the first double-ended screw 18 and the second double-ended screw 19 to align the positions of the four clamping components with the four sides of the test piece 16. Then, the third double-ended screw 22 is rotated to move the clamping plates 21 on both sides inward to clamp the four sides of the test piece 16, preventing the test piece 16 from shaking or even falling during long-term air blowing aging test and vibration test, which can better simulate the situation of car instrument installed in the car.

[0040] The hot air component 2 can continuously blow hot air to test the test piece 16 for aging test. The ozone generating component 3 can blow ozone to accelerate the aging of the rubber parts. The ultraviolet lamp 4 can accelerate aging by irradiating with ultraviolet light.

[0041] The vibration rod 11 can move up and down to drive the test piece 16 to vibrate for testing. The sliding plate 5 can be pulled out from the side of the box 1. During installation and disassembly, it can be quickly disassembled and assembled from the outside of the box 1. When the vibration motor 9 is working, it can drive the cam 10 to rotate. Through the protrusion on one side of the cam 10, the vibration rod 11 is repeatedly squeezed to rise and fall, thus vibrating the test piece 16.

[0043] An aging test device for automotive instruments, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 1-5 As shown,

[0044] In this embodiment, a limiting plate 13 and a spring 12 are fixedly connected to both sides of the vibration rod 11. The lower end of the spring 12 is fixedly connected to the upper side of the vibration bracket 6. The limiting plate 13 can limit the lowest position of the vibration rod 11 when it falls, and the spring 12 can prevent the vibration rod 11 from bouncing up too violently.

[0045] In this embodiment, a plurality of support columns 7 are fixedly connected below the sliding tray 5, and a plurality of rollers 8 are rotatably connected below the support columns 7;

[0046] The support column 7 can be kept stable by the rollers 8 below when the sliding support plate 5 moves outward, and will not tilt.
