Example Embodiment
[0014] Example: such as Figure 1-Figure 3 As shown, the present invention includes a support 1, a positioning block I2, a positioning block II3, and a limiting pin 4. The clamping ends of the positioning block I2 and the positioning block II3 are symmetrically placed on the support 1, passing through cylindrical pins 5 and Hexagon socket head screws 6 are used for fixing. The support 1 has two profiles with different angles. On the angled end of the support 1, there are two positioning blocks I2 and two positioning blocks II. The clamping end surface of the positioning block is matched with the blade tenon.
[0015] Such as figure 2 As shown, the profile I8 and II9 are respectively parallel to the blade cavity axis L, and the profile vertical plane M containing the blade cavity axis L does not intersect any cavity channel of the blade body. The profile I8 is used to detect the 701 and 702 channels of the blade, and the profile II9 is used to test the 703-708 channels of the ...
