[0033] In some embodiments, the processing components are relatively fixed during the processing, while the blades rotate. Due to deviations in the coaxiality of the blades, low processing accuracy often occurs, affecting the yield and efficiency.

[0034] Reference Figures 1-2 As shown, this utility model embodiment provides a cutting device for processing wind turbine blades, comprising:

[0035] Frame size 100;

[0036] The clamping assembly 200 is connected to the frame 100 and is used to clamp and fix the blade 400.
