Method for detecting positioning precision of wind power blade component

The invention relates to the technical field of wind power generation blade detection, in particular to a wind power blade component positioning precision detection method, which comprises the following steps of S1, respectively measuring positioning data of a girder and a web in a wind power blade through three-dimensional design software, the data is the horizontal distance between the front edge side line and the front edge parting line of the blade girder; s2, positioning data of a girder and web plates in the wind power blade are measured through a three-coordinate measuring instrument, the data are actual positioning data, and the data are the horizontal distance between a front edge parting line of the girder and one web plate of the blade; and S3, comparing and analyzing the positioning data measured in the step S2 and the positioning data measured in the step S1, and judging whether the positioning data in the step S2 can meet the design requirement or not, so as to ensure the positioning precision.
