[0035] Working principle:

[0036] As shown in the figure, the two sides of the automobile bumper are placed between the support frame 74 and the fixing block 75 respectively, and the two sides of the automobile bumper are fixed by using the extrusion screw 76. After the fixing is completed, the box door 3 is closed, and the moving frame 62 is controlled to move by the control panel 4. Since the sliding rod 71 penetrates the moving frame 62, it drives the fixing structure 7 to move, thereby driving the automobile bumper to move. During the movement, the operator can observe the position of the automobile bumper in the cylinder 51 by rotating the camera 56;

[0037] When the car bumper is located inside the cylinder 51, the heating tube or ultraviolet lamp can be started through the control panel 4 to test the high temperature resistance and daily irradiation life of the car bumper;

[0038] When the car bumper moves to the position of the electric telescopic rod structure 54, the control panel 4 stops the moving frame 62 from moving, so that the car bumper is stationary directly below the electric telescopic rod structure 54, and the control panel 4 starts the electric telescopic rod to drive the detection head of the ultrasonic detector 8 to move, so that the detection head of the ultrasonic detector 8 contacts the car bumper, and a preliminary detection is performed on the inside of the car bumper. According to the data displayed by the ultrasonic detector 8, it is determined whether there is a crack inside the car bumper; the detected data at this time can be used as the initial car bumper data;

[0039] When the car bumper moves to the position of the nozzle structure 55, the control panel 4 stops the moving frame 62 from moving, so that the car bumper is stationary directly below the nozzle structure 55, and the control panel 4 starts the electromagnetic valve to allow the acidic and alkaline liquid in the liquid storage tank 9 to be sprayed onto the outer surface of the car bumper through the nozzle to perform a corrosion resistance test, and the changes on the outer surface of the car bumper can be observed by rotating the camera 56;

[0040] When an impact test is required, a collision block or a collision car bumper can be installed on the moving frame 62 where the car bumper is not installed. The two electromagnetic slide rails are started to accelerate toward the center through the control panel 4 to make the car bumpers collide. During the collision, the force received will be detected by the side pressure sensor 77, and then the internal damage of the car bumper will be detected by the ultrasonic detector 8. By comparing with the initial car bumper data, the impact resistance ability can be more directly tested.

[0041] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
