The working pressure of the second hydraulic cylinder 37 is dynamically adjusted. The input shaft is inserted into the inner cavity of the lower fitting sleeve 26. Then, the first hydraulic cylinder 22 is extended by controlling the control box 11. The upper fitting sleeve 24 can be moved down by the first connecting seat 23 to realize the function of axial clamping of the input shaft. If the bearing pressure test of the input shaft is required, the first hydraulic cylinder 22 is controlled by the control box 11 to apply axial pressure to the input shaft according to the specified pressure. The upper fitting sleeve 24 is installed on the first connecting seat 23 with screws, and the lower fitting sleeve 26 is installed on the second connecting seat 25 with screws.

[0037] As one implementation method in this embodiment, such as Figure 4As shown, the flexible testing mechanism 3 includes a ring track 31, which is fixedly installed on the top of the testing workbench 1.

The upper fitting sleeve 24 can be moved down through the first connecting seat 23 to achieve the function of axial clamping the input shaft. If it is necessary to perform bearing pressure test on the input shaft, the first hydraulic cylinder 22 can be controlled by the control box 11 to apply axial pressure to the input shaft according to the specified pressure. When performing a flexible test on the side of the input shaft, loosen the first positioning bolt 33, and it can then be moved out of the annular track 31.

This realizes the function of flexibly testing the side of the input shaft. After the input shaft is tested, internal cracks and other defects can be detected non-destructively using existing ultrasonic testing technology.
