The glass fiber wind power blade is one of key parts of a wind turbine generator and is connected to a hub in a certain root connection mode. The most common blade root connection mode is T-bolt connection, and in the design, bolt holes and nut holes are drilled at the root part of the blade by using special drilling equipment after the blade is demoulded, and then bolts and nuts are installed and placed in the bolt holes and the nut holes for connection. In order to ensure that the blade bolt can be well connected with the variable pitch bearing of the wind turbine generator, the blade bolt is required to be ensured to be perpendicular to the end face of the blade, and the design tolerance is usually required to be 0.2 degrees. The bolt that uses on the wind-powered electricity generation blade is stud, and the diameter in bolt both ends area of taking the screw thread is great (like M36), and the slender pole diameter in bolt interlude is less (like phi 28mm), and corresponding blade root bolt hole diameter is a little bigger by 2mm than bolt end diameter (for example, the bolt hole diameter of the blade that M36 bolt place is phi 38 mm). At present, the installation of blade bolt and nut mainly leans on the manual work, but bolt hole diameter ratio bolt diameter is big, and the nut is rotatable in the nut hole, and the bolt can take place to remove at the chord direction in the bolt hole, consequently if only rely on artifical range estimation, can't guarantee the bolt straightness that hangs down of every bolt and satisfy the designing requirement in the installation. If the verticality deviation between the bolt and the end face of the blade root is overlarge, the bolt and the variable pitch bearing of the fan can not be assembled, or the bolt is damaged due to the contact between the blade bolt and the variable pitch bearing in the operation process of the fan.
