The calibration plate is used to simulate the material, and the ultrasonic detection device is used to detect the height of the calibration plate, and compare the height with the measured height to calibrate the detection accuracy of the ultrasonic detection device.

[0024] Specifically, the ultrasonic detection device is set on the roof of the production workshop, and the height of the calibration plate is used to simulate the height of the material. The trolley 10 is pushed to move the calibration frame 40 and the calibration plate to the bottom of the ultrasonic detection device. The ultrasonic detection device uses ultrasonic waves to detect the height of the calibration plate and displays the detection data at the same time. By comparing the detection data with the actual height of the calibration plate, the detection deviation of the ultrasonic detection device can be obtained.

The multiple first connecting rods 44 of each group of first connecting rods 44 are arranged parallel to each other. The calibration plate is placed on any pair of oppositely arranged first connecting rods 44 of the two side frames 43.

[0028] Specifically, a plurality of first connecting rods 44 are symmetrically arranged in two oppositely arranged side frames 43 of the rectangular frame, and each two oppositely arranged first connecting rods 44 are configured as slots for placing the calibration plate, so that the calibration frame 40 has multiple layers of slots. A height of each layer of slots can be preset, and when the calibration plate is inserted into the slot of the layer, the actual height of the calibration plate can be known, and then the actual height is compared with the detection result of the ultrasonic detection device, so as to calibrate the detection accuracy of the ultrasonic detection device.

[0033] Specifically, the plurality of protrusions 45 of the calibration frame 40 are laid on the top surface of the receiving frame 20 , so that the receiving frame 20 becomes the outer frame of the calibration frame 40 to fix the position of the calibration frame 40 .

[0034] like Figure 1 As shown, in the embodiment of the present utility model, the accommodating frame 20 includes: a pair of side panels 21 and a pair of second connecting rods 22.

[0038] Specifically, a box 12 is provided on the vehicle body 11, and the box 12 has a bottom surface and three side surfaces, and a first opening on the top surface so that ultrasound can penetrate the first opening and enter the calibration plate.

[0040] Specifically, the ultrasonic detection device is arranged on the top surface of the workshop, and the calibration device includes: a trolley 10, a calibration frame 40 and a calibration plate (not shown in the figure). The bottom of the trolley 10 is provided with a roller 30, the calibration frame 40 is arranged on the trolley 10, and the calibration plate is arranged on the calibration frame 40. The calibration plate is used to simulate the material, and the ultrasonic detection device is used to detect the height of the calibration plate, and compare the height with the measured height to calibrate the detection accuracy of the ultrasonic detection device.

[0041] Specifically, the ultrasonic detection device is set on the roof of the production workshop, and the height of the calibration plate is used to simulate the height of the material. The trolley 10 is pushed to move the calibration frame 40 and the calibration plate to the bottom of the ultrasonic detection device. The ultrasonic detection device uses ultrasonic waves to detect the height of the calibration plate and displays the detection data at the same time. By comparing the detection data with the actual height of the calibration plate, the detection deviation of the ultrasonic detection device can be obtained.

After a calibration plate is set on the calibration frame 40, the detection data of the ultrasonic detection device is compared with the measured data. After the test, the calibration plate is stacked on the calibration plate, and the thickness of the calibration plate is continuously increased to obtain multiple detection data, and then the detection accuracy of the ultrasonic detection device is obtained by comparing the multiple detection data, and then the ultrasonic detection device is calibrated.
