[0024] Specifically, the diesel engine crankshaft is placed in the middle of the clamping plate 8, and the first motor 3 is started. The two discs 4 are driven to rotate by the first motor 3. The two discs 4 respectively drive the two connecting rods 5 to change their angles. The two connecting rods 5 respectively drive the two rotating rods 6 to change their angles. The two rotating rods 6 respectively drive the two fixed columns 7 to slide up and down inside the fixed platform 10, thereby driving the clamping plate 8 to slide up and down together. The two sets of sliding shafts 11 and the second spring 12 play a buffering and protective role on the clamping plate 8, thereby achieving the effect of automatic lifting and lowering adjustment.

[0025] Reference Figure 1 and Figure 2 One end of the second spring 12 is fixedly connected to the lower surface of the clamping plate 8, and the other end of the second spring 12 is fixedly connected to the upper surface of the fixed platform 10. The upper surface of the operating platform 1 is fixedly connected with a first telescopic rod 13, and the output end of the first telescopic rod 13 is fixedly connected with a first electric slide platform 14. The outer wall of the first electric slide platform 14 is slidably connected with a second motor 15, and the output end of the second motor 15 is fixedly connected with a detection machine 16;

[0026] Specifically, the four first telescopic rods 13 are started, and the four first telescopic rods 13 respectively drive the two first electric slide platforms 14 to perform lifting and lowering adjustment, and the two first electric slide platforms 14 respectively drive the two second motors 15 to approach the clamping plate 8. Because the two second motors 15 respectively drive the two detection machines 16 to rotate, the two detection machines 16 are stuck at both ends of the diesel engine crankshaft to drive the crankshaft to rotate and inspect, thereby achieving the effect of automatic multi-angle inspection.

The two sets of sliding shafts 11 and the second spring 12 play a buffering and protective role for the clamping plate 8, and then start the four first telescopic rods 13 to adjust according to the height of the clamping plate 8, and drive the first electric slide platform 14 to rise and fall through the first telescopic rods 13 to adjust the height to be consistent with the clamping plate 8, and then The first electric slide platform 14 drives the second motor 15 to adjust the position according to the length of the crankshaft, and fits the inspection head of the inspection machine 16 with the crankshaft. The second motor 15 drives the inspection machine 16 to rotate to achieve the inspection effect, and then the second electric slide platform 17 drives the slider 18 to translate back and forth to adjust according to the position required during the inspection process.
