Abstract

The invention discloses a clamping ring for a root end of a composite material blade. The clamping ring comprises a clamping ring main body with a circular cross section and a clamping bracket arranged below the clamping ring main body and integrally formed with the clamping ring main body; an annular installation through groove is formed in the clamping ring main body; a plurality of indexing installation grooves are uniformly arranged in the annular installation through groove; a plurality of upper clamping plates matched with the outer diameter of the blade root end are arranged in the indexing installation grooves closing to a top position in the annular through groove by an upper adjusting device; and a plurality of lower clamping plates matched with the outer diameter of the blade root end are arranged in the indexing installation grooves closing to a bottom position of the annular through groove by a lower adjusting device. The clamping ring for the root end of the composite material blade provided by the invention can achieve better clamping to the root end of the blade by adjusting the upper adjusting device and the lower adjusting device; and the root end of the blade isprevented from shaking and displacing during the swaying and displacement of the root end of the blade during the processing, so that the root end can ensure the completed arc degree.

Description

technical field [0001] The invention belongs to the field of clamping devices, in particular to a clamping ring at the root end of a composite material blade. Background technique [0002] Composite material blades are the main components of wind power generators, and the processing of the root end is a relatively difficult part in the entire processing process. The processing steps are cutting, grinding, drilling axial and radial holes. Since it needs to be processed very precisely before it can be installed on the complete wind turbine, the position and shape of the root end of the blade are particularly important. The root end cannot move during machining and the roundness of the root segment needs to be maintained throughout the process. In order to make wind power generators generate more electricity, the blades are designed to be larger and larger. However, it is very difficult for manufacturers to increase the size of blades while keeping their weight low. At pres...
