Abstract

The invention provides a perforating device and perforating method of a wind power blade, and relates to the field of blade perforating. The perforating device comprises a rack structure, an adjustingdevice and a perforating device. By means of the device, time wasted by hole position surveying and mapping of workers can be reduced. Size errors brought by manual measurement are reduced, and tapemeasures and marking pens are omitted. The problem of poor perforating consistency caused by personnel replacement is reduced. Penetrating damage caused to blades during perforating due to the fact that personal skills and strengths are different is reduced.

Description

technical field [0001] The invention relates to a hole punching device, in particular to a drain hole punching device and a hole punching method for wind power blades. Background technique [0002] As an indispensable structure of the blade, the drainage hole of the wind power blade plays an irreplaceable role. The blade tip of the blade is provided with a hole with a diameter of 8 mm, and forms an angle of 45° with the surface of the blade, and also forms an angle of 45° with the centerline of the blade. It is required to penetrate the SS surface of the blade without damaging the PS surface. Difficulties in this process: [0003] 1. Since the drainage hole is at the tip of the blade, and the tip of the blade is curved, it is difficult to measure its size with a tape measure, and there are large errors. [0004] 2. Guaranteed 2 included angles of 45° with the blade. The operation is completely based on the experience of the workers, which cannot meet the size requirements...
