Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation blade production, in particular to a zero-degree positioning detection tool for wind blades. Background Art

[0002] The installation of the zero-degree mark is the last process before the blade leaves the factory. The mark must be installed according to the process regulations. Currently, the installation of the zero-degree mark is mainly carried out by using a pen ruler, vernier caliper and marker pen to locate it before installation. The following problems exist:

[0003] 1. Before installing the identification plate, it is necessary to determine the circumferential center position of the blade root corresponding to the identification plate. Using a steel ruler to measure the circumferential center of the two bolts cannot accurately find the circumferential center, and there will be errors in the process. 2. Using a vernier caliper to find the point corresponding to the minimum spacing between the two bolt holes is difficult to operate, time-consuming and labor-intensive, and there will be errors. 3. Due to the circumferential distribution of the blade root bolt holes and the large curvature of the profile, when drawing a line connecting two points, the circumferential center point will deviate from the center of the straight line.

[0004] In view of the inconvenience of manual marking and the existence of errors, a more accurate and easy-to-operate zero-degree marking positioning tool is needed to improve the positioning accuracy. Utility Model Content

[0005] The purpose of the utility model is to provide a zero-degree positioning detection tool for wind blades, which has high positioning efficiency.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1-Figure 3 A wind blade zero-degree positioning detection tool comprises a tool plate 1, on which a first limiting post 2 and a second limiting post 3 symmetrically arranged with respect to the first limiting post 2 are mounted;

[0027] A first annular limiting plate 4 and a first conical plug-in block 6 are sequentially provided on the first limiting column 2 from top to bottom, and a second annular limiting plate 5 and a second conical plug-in block 7 are sequentially provided on the second limiting column 3 from top to bottom;

[0028] A first positioning protrusion 8 and a second positioning protrusion 9 are respectively provided on the front and rear sides of the tooling plate 1, and a first positioning opening 10 and a second positioning opening 11 are respectively opened on the first positioning protrusion 8 and the second positioning protrusion 9;

[0029] Directly above the first positioning opening 10 and the second positioning opening 11, a first L-shaped support plate 12 and a second L-shaped support plate 13 are respectively mounted. Both the first L-shaped support plate 12 and the second L-shaped support plate 13 are fixed to the tooling plate 1. A first laser pointer 14 and a second laser pointer 15 are respectively mounted vertically downward on the first L-shaped support plate 12 and the second L-shaped support plate 13. This device is simple and easy to operate, improving positioning efficiency while reducing manpower. It also mitigates the current situation of errors in zero-degree mark positioning and enhances positioning accuracy. It can be used for the rapid positioning and installation of zero-degree marks in mass production of blades, and can also verify the correct installation of zero-degree marks.

[0030] In this embodiment, the tooling plate 1 is arc-shaped, and its inner and outer diameters are the same as the diameter of the shell blade root, so that the circumferential contour line of the tooling plate 1 coincides with the contour lines of the inner and outer diameters of the blade root end face, thereby improving positioning accuracy.

[0031] A rectangular through slot 16 is provided in the middle of the tooling plate 1. In this embodiment, the rectangular through slot 16 can reduce the weight of the tooling and make it easier to operate.

[0032] A docking handle 17 is detachably mounted above the first and second limiting posts 2 and 3. A first threaded groove 18 and a second threaded groove 19 are respectively provided at the top of the first limiting post 2 and the bottom of the second limiting post 3. A first through hole 20 corresponding to the first threaded groove 18 is provided at the left end of the docking handle 17, and a first docking groove 22 is provided at the bottom of the first through hole 20. A second through hole 21 corresponding to the second threaded groove 19 is provided at the right end of the docking handle 17, and a second docking groove 23 is provided at the bottom of the second through hole 21. A first stud 24 is screwed into the interior of the first threaded groove 18, and a first stud 24 is screwed into the interior of the second threaded groove 19. In this embodiment, disassembly and maintenance can be achieved through two studs, which is simple and quick. During installation, the first limit column 2 and the second limit column 3 are inserted into the corresponding openings on the tooling plate 1. At this time, the first annular limit plate 4 and the second annular limit plate 5 are in contact with the bottom of the tooling plate 1. This step can make the first limit column 2 and the second limit column 3 have the same length below the tooling plate 1 during installation. Then, the first docking groove 22 and the second docking groove 23 on the docking handle 17 are placed above the first limit column 2 and the second limit column 3 respectively. The first stud 24 is screwed to the inside of the first threaded groove 18 through the first through hole 20, and the second stud 25 is screwed to the inside of the second threaded groove 19 through the second through hole 21 to complete the assembly.

[0033] Working principle: The first limiting column 2 and the second limiting column 3 on the tooling plate 1 are inserted into the two adjacent bolt holes of the blade root through the docking handle 17. The bottoms of the first limiting column 2 and the second limiting column 3 are in contact with the bottoms of the two bolt holes. At this time, the first conical plug-in block 6 and the second conical plug-in block 7 are in contact with the hole walls of the bolt holes, which can achieve stable support of the tooling plate 1.

[0034] According to the positions of the first positioning opening 10 and the second positioning opening 11 and under the action of the first laser pointer 14 and the second laser pointer 15, marks are made on the inner and outer circumferential directions of the blade root of the shell, and the zero degree mark is installed on the inner and outer circumferential directions of the blade root according to the made marks.
