Among them, the first direction X is the length extension direction of the first blade 20 and the second blade 30, and the second direction Z is the vertical direction.

[0026] For the above-mentioned housing 10, as Figure 1 and Figure 2 shown, the housing 10 is provided with an installation platform 10a. The above-mentioned first blade 20, second blade 30, multiple first clamping plate assemblies 40, and multiple second clamping plate assemblies 50 are all arranged on the installation platform 10a. The bottom of the housing 10 is also provided with multiple rollers 101, and the multiple rollers 101 can drive the housing 10 to move to different positions.

[0027] In some embodiments, a scale 102 is further provided on the housing 10. The scale 102 is located on the installation platform 10a and extends along the first direction X. The coordinates of the multiple first clamping plate assemblies 40 on the first blade 20 along the first direction X can be measured by using the scale 102.

[0028] For the above-mentioned first blade 20 and multiple first clamping plate assemblies 40, as Figures 1 - 3As shown, the first clamping plate assembly 40 includes a first clamping plate 401 and a first support plate 402.

The first blade 20 sequentially passes through the first card slots 401a on the plurality of first clamping plate assemblies 40 along the first direction X. The first clamping plate 401 can move relative to the first support plate 402 in the second direction Z and the third direction Y so that the first card slot 401a fits against the outer surface of the first blade 20. Along the second direction Z, the distance from the upper plane of the first clamping plate 401 to the upper plane of the first support plate 402 is H. The first clamping plate 401 has a first side surface, and the first support plate 402 has a second side surface. The second side surface is parallel to and on the same side as the first side surface. Along the third direction Y, the distance from the first side surface to the second side surface is h. Taking the movement process of a single first clamping plate assembly 40 as an example for illustration, during the actual detection process, the first blade 20 to be detected is detachably and stably mounted on the mounting platform 10a of the casing 10. A single first clamping plate assembly 40 is sleeved on a certain section of the first blade 20. A certain section of the first blade 20 is sleeved in the first card slot 401a. The first support plate 402 is fixed on the mounting platform 10a. The user can move the first clamping plate 401 in the second direction Z and the third direction Y to make the first card slot 401a on the first clamping plate 401 fit against the outer surface of the first blade 20. The inner wall of the first card slot 401a is adapted to the outer shape of the first blade. At this time, the user can measure the corresponding data H and h. When the values of H and h are both within the preset range, the airfoil of the first blade 20 is a qualified product.

[0030] In some embodiments, the first card slot 401a includes a first inner wall 401aa and a second inner wall 401ab that are oppositely disposed along the second direction Z.

Optionally, both the first inner wall 401aa and the second inner wall 401ab are arc-shaped surfaces to adapt to the arc-shaped surface of the first blade 20.

[0031] In some embodiments, the first clamping plate 401 includes an upper cover plate 4011 and a lower bottom plate 4012. The upper cover plate 4011 covers the lower bottom plate 4012. One side of the upper cover plate 4011 is rotatably connected to one side of the lower bottom plate 4012, and the other side of the upper cover plate 4011 is detachably connected to the other side of the lower bottom plate 4012. The upper cover plate 4011 can open or close the first clamping groove 401a. Optionally, the first inner wall 401aa is located on the upper cover plate 4011, and the second inner wall 401ab is located on the lower bottom plate 4012. After the first paddle 20 is disposed on the mounting platform 10a, the user can open the first clamping groove 401a through the upper cover plate 4011, and snap a part of the first paddle 20 into the first clamping groove 401a. Then, the other side of the upper cover plate 4011 and the other side of the lower bottom plate 4012 are connected by screws. The upper cover plate 4011 closes the first clamping groove 401a, and the first clamping plate 401 is sleeved on the first paddle 20.

[0032] In some embodiments, the first clamping plate assembly 40 further includes two limiting blocks 403. The two limiting blocks 403 are spaced along the first direction X on the outer side wall of the lower bottom plate 4012, and the two limiting blocks 403 are located at the connection between the upper cover plate 4011 and the lower bottom plate 4012. When the upper cover plate 4011 covers the lower bottom plate 4012, the two limiting blocks 403 can reduce the movement of the upper cover plate 4011 in the first direction X to limit the position of the upper cover plate 4011.

[0033] In some embodiments, please refer to Figure 4 together, a limiting stop block 4021 extends along the second direction Z on the first support plate 402. The first clamping plate 401 abuts against the limiting stop block 4021, and the limiting stop block 4021 can limit the movement of the first clamping plate 401 in the first direction X.

The fixing hole 40211 is arranged at least partially opposite to the adjusting through hole 401b. The first clamping plate assembly 40 also includes a fixing screw 404, a fixing block 405 and a gasket 406. The fixing block 405 and the gasket 406 are both arranged on the side of the first clamping plate 401 away from the limit stop block 4021, and the gasket 406 is located between the fixing block 405 and the first clamping plate 401. One end of the fixing screw 404 passes through the fixing hole 40211, the adjusting through hole 401b and the gasket 406 in sequence and is connected to the fixing block 405, and the adjusting through hole 401b can move in the second direction Z and the third direction Y relative to the fixing screw 404. The user can loosen the fixing screw 404. At this time, the adjustment through hole 401b on the first clamping plate 401 can move in the second direction Z and the third direction Y relative to the fixing screw 404 to adjust the relative position between the first clamping slot 401a on the first clamping plate 401 and the outer surface of the first blade 20. When the first clamping slot 401a is in contact with the outer surface of the first blade 20, the user can tighten the fixing screw 404 to relatively fix the first clamping plate 401 to the first support plate 402 for subsequent measurement of H and h data.

[0035] In some embodiments, the first card plate assembly 40 also includes an adjusting member 407, and the adjusting member 407 includes a connecting block 4071 and a first adjusting screw 4072.

The axial direction of the first adjusting hole 40711 is along the third direction Y. One end of the first adjusting screw 4072 is inserted into the first adjusting hole 40711 and abuts against the first support plate 402. Since the connecting block 4071 is connected to the first card plate 401, the user can adjust the distance between the connecting block 4071 and the first support plate 402 along the third direction Y by rotating the first adjusting screw 4072. The connecting block 4071 can drive the first card plate 401 to move in the third direction Y, thereby realizing the position adjustment of the first card plate 401 relative to the first support plate 402 in the third direction Y.

[0036] In some embodiments, the adjusting member 407 further includes a second adjusting screw 4073. A second adjusting hole 40712 is further provided on the connecting block 4071. The axial direction of the second adjusting hole 40712 is along the second direction Z.

The user can adjust the distance between the connecting block 4071 and the first support plate 402 along the second direction Z by rotating the second adjusting screw 4073. The connecting block 4071 can drive the first clamping plate 401 to move in the second direction Z, so as to realize the position adjustment of the first clamping plate 401 relative to the first support plate 402 in the second direction Z.

At this time, the user can measure the corresponding data L1 and L2. When the values of L1 and L2 are both within the preset range, the airfoil of the second blade 30 is a qualified product.
