[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] AsFigure 1 As shown in the figure, this embodiment provides a positioning tooling for wind turbine blades, which includes a support assembly, a measuring ruler 4, a first slide rail (not shown in the figure), a first angle gauge 6, a second angle gauge 7, a movable base 8, a rotating arm 9, and a positioning laser pen 10. There are two support assemblies, which are symmetrically arranged on the front and rear flange of the blade shell mold 12 in the left and right directions. The measuring ruler 4 is mounted on the two support assemblies and is located above the blade shell mold 12. A first angle gauge 6 is arranged on the top surface of the measuring ruler 4 to judge the levelness of the measuring ruler 4 through the first angle gauge 6, and further control the relative position relationship between the support rod 2 and the measuring ruler 4. A first slide rail for installing the movable base 8 is arranged on the bottom surface of the measuring ruler 4. There are multiple movable bases 8, which are respectively installed on the first slide rail through sliders and can respectively move horizontally along the first slide rail. The bottom of each first slide rail is hinged with a rotating arm 9, and a second angle gauge 7 is arranged on the side surface of each rotating arm 9, and a positioning laser pen 10 is arranged at its bottom.

[0024] As Figure 2 As shown in the figure, the support assembly includes a fixed base 1, a support rod 2, and a measuring ruler support 3. The bottom of the support rod 2 is connected to the fixed base 1. A second slide rail 5 for installing the measuring ruler support 3 is longitudinally arranged on the side surface of the support rod 2. The measuring ruler support 3 is slidably installed on the second slide rail 5 through a slider. The height of the measuring ruler 4 is adjusted through the measuring ruler support 3, and then the position of the measuring ruler support 3 is fixed by bolts.

[0025] As Figure 3 As shown in the figure, the positioning laser pen 10 is connected to the rotating arm 9 through a concentric sleeve 11 at its bottom.

[0026] In this embodiment, there are four movable bases 8, and the specific number can be set according to actual positioning requirements.

[0027] To reduce the mass of the tooling, the above-mentioned support assembly, measuring ruler 4, first slide rail, movable base 8, and rotating arm 9 are all made of aluminum parts, which facilitates on-site operation by reducing the overall weight.

[0028] The working principle of the above positioning tooling is as follows:

[0029] During the chordal positioning of components in the blade production process, taking the position marks (axial meter scale markings) on the front and rear flange of the mold as the reference, the two sides of the measuring ruler in the axial direction are placed flush with the axial meter scale markings respectively, and the measuring ruler is adjusted to the horizontal state through the first angle gauge.

[0030] Subsequently, by making the inclination angle of the rotating arm consistent with the inclination angle of the mold end face, at this time, a plane (three points form a plane) is formed by the point indicated by the laser pen and the axial meter scale markings on the front and rear edges of the mold respectively. At this time, this cross-section is consistent with the target theoretical cross-section.

[0031] Finally, the chordwise position of the rotating arm is adjusted through the chordwise positioning data of each component in the theoretical section by means of the movable base. When the chordwise reading on the measuring scale is consistent with the theoretical positioning data, the point indicated by the laser pen at this time is the chordwise positioning point of the component at this axial position.

[0032] The specific implementation steps of using the present utility model for positioning in the actual production process of the blade are as follows:

[0033] S1. Determine the axial meter mark lines at the leading and trailing edges of the blade housing mold;

[0034] S2. As shown in, place the two support components on the flanges at the leading and trailing edges of the blade housing mold respectively; Figure 4 shown, place the two support components on the flanges at the leading and trailing edges of the blade housing mold respectively;

[0035] S3. Place the measuring scale above the meter mark line, ensure that its edge line is flush with the meter mark line, and then place the measuring scale on the two support components, close to the support rods;

[0036] S4. Install the first angle gauge on the measuring scale, and adjust the relative height of the measuring scale on the support components by reading the first angle gauge until the reading of the first angle gauge is within the range of 0±0.2°;

[0037] S5. Rotate the rotating arm to ensure that the reading of the second angle gauge on its surface is consistent with the inclination angle of the mold end face. After the inclination angles are consistent, fix the rotating arm to the movable base to maintain the stability of the inclination angle during the subsequent measurement process;

[0038] S6. According to the chordwise horizontal positioning of the component in the empty mold, adjust the relative position between the rotating arm and the measuring scale until the reading on the measuring scale is consistent with the chordwise horizontal positioning of the empty mold;

[0039] S7. Record the position of the light spot of the laser pen in the inner cavity of the housing at this time, and make marks in the corresponding area. This mark is the true chordwise positioning of the component on the mold at this time;

[0040] If the chordwise positioning of the components needs to be carried out at the leading and trailing edges of the mold simultaneously, only the movable base, rotating arm, second angle gauge, concentric sleeve and laser pen need to be added.

[0041] The above is only a preferred embodiment of the patent of the present utility model, but the protection scope of the patent of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the patent of the present utility model, according to the technical solution of the patent of the present utility model and its inventive concept, makes equivalent substitutions or changes, all belong to the protection scope of the patent of the present utility model.
