Abstract

The invention relates to the technical field of blade welding, and discloses a blade welding device for a wind driven generator. The blade welding device comprises a mounting support A and a mounting support B which are combined to form a mounting frame, a machining table is arranged in the mounting frame, a jig seat is movably arranged at the top of the machining table, a limiting groove matched with a wind driven generator blade in shape is formed in the top of the jig seat, a vertical displacement assembly for driving the jig seat to ascend and descend is fixedly arranged at the top of the machining table, a blade clamping assembly is fixedly arranged at the top of the machining table, and a sliding seat moving assembly is fixedly arranged between the mounting support A and the mounting support B. According to the blade welding device for the wind driven generator, the problem that welding is not accurate enough due to the fact that broken blades are not placed accurately is solved, cracks are ground flat while the two broken blades are extruded through a blade extruding and grinding assembly, the two broken blades make full contact, and therefore the welding effect of the wind driven generator blades is improved.

Description

technical field [0001] The invention relates to the technical field of blade welding, in particular to a blade welding device for wind power generators. Background technique [0002] The design of blades in wind turbines directly affects the conversion efficiency of wind energy and its annual power generation, which is an important part of wind energy utilization. The metal blades used in small and medium-sized wind turbines will break the blades during long-term use, and the existing blade welding device will fix the blades and then weld them, without preprocessing the position of the broken blades, making the wind turbines The welding of the blades is not precise enough, and it may be because there is a gap between the two broken blades, which reduces the welding effect of the broken blades, and the blades of the wind turbine may not be ground on the surface of the blades due to the inclination. Flat treatment makes it difficult to achieve the characteristics of the origi...
