Description

Technical Field

[0001] The utility model relates to the technical field of inspection tooling, in particular to an inspection tooling for water droplet core materials of wind turbine blades. Background Art

[0002] With the rapid development of the wind power industry, wind turbine blades are developing towards higher and larger heights. The ordinary single main beam can no longer meet the strength requirements of the blades. Therefore, auxiliary beams are added to the blades. The water drop core material is the beginning and end of the auxiliary beam. It plays the role of smooth transition connection between the auxiliary beam and the core material at other positions. The shape is slightly more complicated than the conventional core material, and it cannot be processed and formed normally in one time. Deviations may occur after forming;

[0003] In order to check whether the water drop core material is qualified and avoid accidents during blade filling, the size and shape are usually measured manually. The inspection efficiency is low and the error is large, which cannot meet the actual use needs. Utility Model Content

[0004] The purpose of the utility model is to provide a wind turbine blade water droplet core material inspection tool to solve the technical problems raised in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a wind turbine blade water droplet core material inspection tool, comprising:

[0006] A male mold, which is used to measure the cutting size and cutting shape of the water drop core material;

[0007] A female mold has an upper surface provided with a groove, which is used to measure the size and shape of the cut water drop core material. The outer wall of the male mold and the outer wall of the water drop core material can be snapped into the inner wall of the groove. When the male mold or the water drop core material is snapped into the groove, the size and shape of the water drop core material can be detected by comparing the positions of the male mold and the water drop core material in the groove.

[0008] Preferably, a circular groove is provided on the inner wall of the female mold and located on the inner side of the groove, the circular groove is communicated with the groove, and the circular groove is located at the corner of the groove.

[0009] Preferably, when the male mold or the water-drop core material is clamped in the groove, the height difference between the upper surface of the male mold or the water-drop core material and the upper surface of the groove is less than 1 mm.

[0010] Compared with the related art, the wind turbine blade water droplet core material inspection tool provided by the utility model has the following beneficial effects:

[0011] The utility model provides a wind turbine blade water drop core material inspection tooling, which processes a female mold and a male mold tooling through a CNC five-axis CNC machine tool. The size, shape and thickness of the male mold are designed in a 1:1 ratio according to the water drop core material. In actual use, the male mold is taken down as a reference, and the size, shape and thickness of the water drop core material are processed. After the water drop core material is produced, the water drop core material is placed in the female mold tooling to check whether the water drop core material and the female mold are spliced ​​together and whether the thickness is consistent. When the distance difference and the upper surface difference between the water drop core material and the female mold are less than 1 mm, it meets the design requirements of the drawing. This method is simple to operate and effectively improves the inspection efficiency of the water drop core material. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] Example:

[0018] See also Figure 1-Figure 3 , the utility model provides a technical solution: a wind turbine blade water drop core material inspection tool, a male mold 2, the male mold 2 is used to measure the cutting size and cutting shape of the water drop core material;

[0019] The female mold 1 has a groove 3 on its upper surface, and the groove 3 is used to measure the size and shape of the cut water drop core material. The outer wall of the male mold 2 and the outer wall of the water drop core material can be snapped into the inner wall of the groove 3. When the male mold 2 or the water drop core material is snapped into the groove 3, the size and shape of the water drop core material can be detected by comparing the positions of the male mold 2 and the water drop core material in the groove 3. When the male mold 2 or the water drop core material is snapped into the groove 3, the height difference between the upper surface of the male mold 2 or the water drop core material and the upper surface of the groove 3 is less than 1mm. The female mold 1 and the male mold 2 tooling are processed by a CNC five-axis CNC machine tool. The size, shape and thickness of the male mold 2 are designed 1:1 according to the water drop core material. In actual use, the male mold 2 is removed for reference, and the size, shape and thickness of the water drop core material are processed. After the water drop core material is produced, the water drop core material is placed in the female mold 1 tooling to check whether the water drop core material and the female mold 1 are spliced ​​together and whether the thickness is consistent. When the water drop core material is small, it is easy to shake in the groove 3, which does not meet the requirements of the drawing design. When the water drop core material is large, it cannot be placed in the groove 3, which does not meet the requirements of the drawing design. When the water drop core material is placed in the groove 3, and the distance difference and the upper surface difference between the water drop core material and the female mold 1 are less than 1mm, it meets the requirements of the drawing design. This female mold 1 tooling is easy to operate and effectively improves the inspection efficiency of the water drop core material.

[0020] In this embodiment, a circular groove 4 is provided on the inner wall of the female mold 1 and located on the inner side of the groove 3. The circular groove 4 is connected to the groove 3 and is located at the corner of the groove 3. After the male mold 2 or the water drop core material is clamped in the groove 3 for inspection, the male mold 2 or the water drop core material can be conveniently removed from the groove 3 through the circular groove 4.

[0021] Working principle: The female mold 1 and the male mold 2 are processed by the CNC five-axis CNC machine tool. The size, shape and thickness of the male mold 2 are designed in 1:1 according to the water drop core material. In actual use, the male mold 2 is removed for reference to process the size, shape and thickness of the water drop core material. After the water drop core material is produced, the water drop core material is placed in the female mold 1 tooling to check whether the splicing of the water drop core material and the female mold 1 is consistent and whether the thickness is consistent. When the water drop core material is small, it is easy to shake in the groove 3, which does not meet the requirements of the drawing design. When the water drop core material is large, it cannot be placed in the groove 3, which does not meet the requirements of the drawing design. When the distance difference and the upper surface difference between the water drop core material and the female mold 1 are less than 1mm, it meets the requirements of the drawing design. This method is easy to operate and effectively improves the inspection efficiency of the water drop core material.
