A stepping motor 23 is fixedly installed on the left side of the vertical seat one 21. Rotating disks 24 are rotatably connected to the adjacent sides of the vertical seat one 21 and the vertical seat two 22. A connecting arm 25 is welded on the outer wall of the rotating disk 24. One end of the connecting arm 25 far from the rotating disk 24 is fixedly installed with a receiving strip 251. A cylinder 252 is fixedly installed on the side surface of the receiving strip 251. The telescopic end of the cylinder 252 extends to the other side of the receiving strip 251 and is fixedly connected with a receiving block 253. A fitting clamping member 254 is detachably connected to the outer surface of the side of the receiving block 253 far from the cylinder 252.

The driven sliding plate 255 can slide in the receiving strip 251 along with the telescopic movement of the cylinder 252, increasing the stability of the receiving block 253. Through the design of the scale line 256, the operator can calculate the length data of the rear torsion beam main body 12, improving the detection efficiency. Then, the stepping motor 23 can be controlled to work, driving the rotating disk 24 and the rear torsion beam main body 12 as a whole to rotate, realizing the automatic flipping of the rear torsion beam main body 12 to adjust the detection position of the rear torsion beam main body 12, reducing the consumption of manpower, and further improving the detection efficiency.

Through the cooperation of the lifting seat 28 and the support bar 29, the support frame 291 can be lifted and supported, and the operation of the surface light source 293 can be controlled. Light can be output through the transparent plate 292 to realize the function of fill-in-light processing of the detection environment, thereby improving the detection effect. Through the cooperation of the aluminum alloy top plate 294 and the heat dissipation fin 295, the heat dissipation efficiency of the surface light source 293 can be improved.

[0024] Working principle: first, the rear torsion beam body 12 is clamped in the fitting support 272, and then the cylinder 252 is controlled to extend, driving the fitting clamping member 254 to move toward the rear torsion beam body 12 to clamp the rear torsion beam body 12, and then the electric telescopic rod 27 is controlled to contract to lower the height of the fitting support 272. Then, the rear torsion beam body 12 can be inspected through the operation of the detection component body 11. During the detection process, the stepper motor 23 is controlled to work, driving the rotating disk 24 and the rear torsion beam body 12 to rotate as a whole, thereby realizing the function of automatically flipping the rear torsion beam body 12 to adjust the detection position of the rear torsion beam body 12.
