A cylinder 14 is rotatably installed on one side of the first positioning frame 11 and one side of the second positioning frame 12. A connecting block 15 is fixedly installed at the output end of the cylinder 14. A rotating frame 16 is rotatably installed on the connecting block 15. An upper pressing block 17 is fixedly installed on the lower surface of the rotating frame 16. A lower pressing block 18 is fixedly installed on the first positioning frame 11 and the second positioning frame 12. The upper pressing block 17 and the lower pressing block 18 are both L-shaped and located on the same horizontal plane. A connecting plate 19 is fixedly installed on the rotating frame 16. The lower end of the connecting plate 19 is rotatably connected to the first positioning frame 11 and the second positioning frame 12. A triangular block is fixedly installed on the bottom of one side of the first positioning frame 11, the second positioning frame 12 and the third positioning frame 13.

[0024] The components on the car body are placed between the first positioning frame 11 and the second positioning frame 12. The lower surface of the car body component is in contact with the lower pressure block 18. The output end of the cylinder 14 pushes the connecting block 15 to drive the rotating frame 16 to rotate. The rotating frame 16 rotates along the first positioning frame 11 and the second positioning frame 12 with the connecting plate 19 as the center, so that the upper pressure block 17 on the rotating frame 16 is in contact with the upper surface of the car body component to fix the car body component. The first positioning frame 11 fixes the two ends of the car body component, and the third positioning frame 13 fixes the middle of the car body component. The second positioning frame 12 is located between the first positioning frame 11 and the third positioning frame 13, and the first positioning frame 11, the second positioning frame 12 and the third positioning frame 13 are distributed at the same distance, so as to achieve accurate positioning of the entire car body component and improve the accuracy of the inspection tool.

[0025] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a first bottom block 2 is fixedly provided on the upper end of the third positioning frame 13, and a first top block 21 is provided above the first bottom block 2; the first bottom block 2 is in contact with the lower surface of the car body parts, and the first top block 21 is in contact with the upper surface of the car body parts. By passing screws through the first bottom block 2, the groove on the car body parts and the first top block 21, the positioning stability of the car body parts is improved.

[0026] In the specific implementation process, such as Figure 1 and Figure 3 As shown, a fixing block 3 is fixedly provided on one side of the first positioning frame 11, and a limiting shaft 31 is fixedly provided on the upper end of the fixing block 3. The upper end of the limiting shaft 31 is conical. The limiting shaft 31 passes through the groove on the car body parts to accurately position the car body parts.

[0027] In the specific implementation process, such as Figure 1 and Figure 4 As shown, a support block 4 is fixedly provided on one side of the second positioning frame 12, and a second bottom block 41 is fixedly provided on the upper surface of the support block 4. A second top block 42 is provided above the second bottom block 41. The second bottom block 41 is in contact with the lower surface of the car body component, and the second top block 42 is in contact with the upper surface of the car body component. The stability of the positioning of the car body component is improved by passing screws through the second bottom block 41, the car body component, and the second top block 42. The grooves on the second bottom block 41, the second top block 42, the first top block 21, and the first bottom block 2 are adapted to the grooves on the car body component.

[0028] Specifically, the working principle and operation method of this utility model are as follows:

[0029] The components on the car body are placed between the first positioning frame 11 and the second positioning frame 12. The lower surface of the car body component is in contact with the lower pressure block 18. The output end of the cylinder 14 pushes the connecting block 15 to drive the rotating frame 16 to rotate. The rotating frame 16 rotates along the first positioning frame 11 and the second positioning frame 12 with the connecting plate 19 as the center, so that the upper pressure block 17 on the rotating frame 16 is in contact with the upper surface of the car body component. The car body component is fixed in sections, making the inspection of the car body component more accurate.
