The utility model drives the laser rangefinder to move between the root and the tail of the blade by the driving mechanism so that the laser rangefinder detects the bending deformation between the root and the tail of the corresponding surface of the blade, and has the characteristics of accurate detection and high detection efficiency.

[0026] Among them, the laser rangefinder 3 specification can adopt option 1.

[0027] Among them, the bending deformation of the fan blade 100 in the utility model can also be interpreted as the fan blade 100 drooping (that is, the root and the tail of the fan blade 100 are not in the same plane).

[0028] In other embodiments, the frame 1 is provided with a clamping mechanism 2 for clamping and positioning the fan blade 100 and a laser rangefinder 3. The frame 1 is provided with a driving mechanism 4 for driving the clamping mechanism 2 to move relative to the laser rangefinder 3. When the driving mechanism 4 drives the clamping mechanism 2 to drive the fan blade 100 to move along the length direction of the fan blade 100, the laser rangefinder 3 detects the bending deformation between the root and the tail of the corresponding surface of the fan blade 100.

This embodiment has the advantages of stable transmission, no noise, high transmission efficiency and high transmission accuracy through the driving screw and the driving nut transmission. In this embodiment, the driving mechanism 4 is symmetrically arranged on the frame, so that the driving handwheels 43 are correspondingly located at the two ends of the frame, which is convenient for the staff to operate the corresponding driving handwheels 43 to avoid interference.

During clamping and positioning, the staff only needs to place the fan blade to be tested in the clamping and positioning recess 21 for positioning to achieve positioning and clamping.

[0036] In other embodiments, in order to clamp more stably and firmly, the clamping mechanism 2 includes an elastic clamping claw provided on the frame 1 for clamping the corresponding part of the fan blade 100. For example, the elastic clamping claw includes a clamping fixture provided on the frame and a clamping flipping piece hinged on the clamping fixture and cooperating with the clamping fixture to clamp the fan blade. A clamping torsion spring is provided between the clamping flipping piece and the clamping fixture to ensure that the elastic clamping claw clamps the fan blade firmly. The clamping positioning recess 21 can be provided on the clamping fixture.

[0037] like Figure 1 As shown, the clamping mechanism 2 includes a connecting hole provided on the frame 1 and used to align and connect with the mounting hole 110 of the fan blade 100, and a connecting screw / screw 22 is passed between the connecting hole and the mounting hole 110 to fix the fan blade 100 relative to the frame 1. During clamping and positioning, the staff places the fan blade to be tested in the clamping and positioning recess 21 for positioning. At this time, the mounting hole 110 is aligned and connected with the connecting hole, and then the staff passes the connecting screw / screw 22 through the connecting hole and the mounting hole 110 at the same time to fix the fan blade 100 relative to the frame 1.
