A wind power blade root skin cutting device

Abstract

The invention discloses a blade root skin cutting device of a wind power blade. The device cuts along a set trajectory of a guide rail. The guide rail is made of glass fiber reinforced plastic following the shape of a mold, and can perform curved cutting to keep the cutting amount consistent. In addition, the cutting mechanism can move chordwise and height on the guide rail to adjust the cutting position and cutting amount, thus ensuring the accuracy of the cutting track. Using this device for profiling automatic cutting not only ensures the cutting quality, but also greatly improves the cutting efficiency.

Description

technical field [0001] The invention relates to the field of wind power blade processing equipment, in particular to a wind power blade root skin cutting device. Background technique [0002] Wind power blades, especially megawatt wind power blades, are usually bonded by two half-skins formed by vacuum infusion. In the production process of wind power blades, before the edges of the two halves of the skin are bonded, it is necessary to cut and polish the end face of the joint of the blade root, so as to meet the requirements of the blade clamping and ensure the quality of the blade after clamping. [0003] At present, in the production process of wind power blade skins, blade root cutting is mostly done manually by using an angle grinder. When the angle grinder is cutting and grinding, since there is no positioning device and the saw blade is small, manual grinding is required after cutting to meet the process requirements. The degree of cutting and grinding depends entirel...

Problems solved by technology

[0005] 1) The moving operation is complicated: the weight is more than 1 ton, and it must be hoisted by crane. It is also proposed to divide the equipment into several parts, and then assemble them into one after manual transportation to the site. Although the utilization rate of the crane is reduced, the assembly time of the equipment is increased, and the consumption long time and complicated operation;

[0006] 2) It can only cut straight lines, and the existing skin cutting machines cannot cut curves, and cannot completely follow the shape

With the continuous development of the wind power industry, the shape of wind power blades is constantly updated, and the mold joints of many blade roots are curved, which makes automatic skin cutting unsuitable
