[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] In order to facilitate the understanding of the positioning tooling and wind turbine blade mold provided by the utility model, its application background is first explained. With the development of large-scale wind turbine blades, the blades generally contain various beam structures. The laying accuracy of the beam structure has a significant impact on the performance of the blade. Therefore, the positioning of the beam structure during the laying process is particularly important.
[0036] In the related art, simple tools such as tape measures or wire boxes are generally used to position the auxiliary beam based on the rear edge or the rear edge of the main beam.
[0037] However, when using the above positioning method, the positioning reference is not unified, and simple tools such as tape measures and wire boxes are easily affected by the operator's proficiency and operating techniques, making it difficult to ensure positioning accuracy.
[0038] Based on the above, the utility model provides a positioning tool and a wind turbine blade mold, which are used to ensure the positioning accuracy of the beam structure and improve the quality of the blade.
[0039] Combine the following Figure 1 The utility model describes a positioning tool and a wind turbine blade mold.
[0040] Reference Figure 1 A positioning tool is suitable for being installed on a blade mold, which includes a first bracket 1, a second bracket 2, a positioning card plate 3, a first adjustment structure 4 and a second adjustment structure 5; wherein the first bracket 1 is arranged along a first direction; the second bracket 2 is arranged along a second direction and connected to the first bracket 1, and the first direction and the second direction are arranged at an angle; one end of the positioning card plate 3 is connected to the second bracket 2, and a positioning portion is formed at the other opposite end, which is suitable for extending into the laying position of the positioning beam in the blade mold; the first adjustment structure 4 is arranged between the first bracket 1 and the second bracket 2, and is used to adjust the position of the second bracket 2 along the first direction, thereby adjusting the position of the positioning card plate 3 along the first direction, and the second adjustment structure 5 is arranged between the positioning card plate 3 and the second bracket 2, and is used to adjust the position of the positioning card plate 3 along the second direction.
[0041] In actual applications, the positioning tooling is installed on the blade mold. Specifically, the first bracket 1 is fixedly connected to the blade mold, and the positioning portion of the positioning clamp 3 extends into the blade mold to locate the laying position of the auxiliary beam. The blade mold is used as a positioning reference, so that the positioning reference is not affected by the thickness of the blade ply; the first adjustment structure 4 can adjust the position of the second bracket 2 along the first direction, thereby adjusting the position of the clamp along the first direction, and the second adjustment structure 5 can adjust the position of the positioning clamp 3 along the second direction, thereby adjusting the position of the clamp along the second direction. Through the cooperation of the first adjustment structure 4 and the second adjustment structure 5, the positioning clamp 3 can be adjusted to any position within the plane formed by the first direction and the second direction, thereby improving the applicability and making the positioning tooling suitable for the production of blades of different models.
[0042] The specific structure of the first bracket 1 and the second bracket 2 can be selected according to actual needs, as long as the required support effect can be achieved; similarly, the specific shape, material and structure of the positioning clamp 3 can also be flexibly configured according to actual needs, as long as the positioning part can be extended into the blade mold after the positioning tooling is installed on the blade mold to achieve the required positioning effect.
[0043] In this embodiment, one end of the first bracket 1 used to connect to the blade mold is the connecting end; the positioning clamp 3 can be made of aluminum alloy, which is arc-shaped as a whole and the outer arc surface protrudes in the direction away from the first bracket 1. One end of the positioning clamp 3 is connected to the second bracket 2, and the other end gradually moves away from the second bracket 2 and extends toward the connecting end of the first bracket 1. A positioning portion is formed at its end to ensure that after the first bracket 1 is connected to the blade mold, the positioning portion of the positioning clamp 3 can extend into the laying position of the positioning beam structure inside the blade mold.
[0044] Specifically, the angle between the first direction and the second direction is 90 degrees. When the positioning tool is installed on the mold, the first direction is the vertical direction, and the second direction is the horizontal direction. The side of the positioning part facing away from the first bracket 1 is set as a plane extending along the first direction, that is, after the positioning tool is installed on the blade mold, the side of the positioning part facing away from the first bracket 1 is formed into a vertical plane to ensure that the beam structure can be abutted against the positioning part to achieve precise positioning effect, and there is a smooth transition between the plane and the outer arc surface of the positioning clamp 3. The outer arc surface of the positioning clamp 3 can play a role of giving way to avoid the collision between the beam structure and the positioning clamp 3 when it is hoisted into the blade mold.
[0045] In practical applications, the positioning fixture is installed on the blade mold, and the positioning portion of the positioning clamp 3 extends into the blade mold to position the beam laying position; the position of the positioning clamp 3 can be adjusted along the first direction and the second direction through the first adjustment structure 4 and the second adjustment structure 5, so as to be suitable for the production of blades of different models. The first adjustment structure 4 and the second adjustment structure 5 will be described in detail below with reference to the accompanying drawings.
[0046] It is understandable that the first adjustment structure 4 can be a structure independent of the first bracket 1, that is, the first bracket 1 only plays a supporting role, and the first adjustment structure 4 only plays an adjusting role. It can also be used as part or all of the first bracket 1, so that the first adjustment structure 4 plays both a supporting role and an adjusting role. For example, a structure or component that has both an adjusting and a supporting role is used, such as a cylinder, an oil cylinder, an electric push rod, a screw and a screw nut that cooperate with each other; similarly, the second adjustment structure 5 can be a structure independent of the second bracket 2, that is, the second bracket 2 only plays a supporting role, and the second adjustment structure 5 only plays an adjusting role. It can also be used as part or all of the second bracket 2, so that the second adjustment structure 5 plays both a supporting and an adjusting role. The first adjustment structure 4 and the second adjustment structure 5 can be flexibly configured according to actual application scenarios and needs.
[0047] In this embodiment, refer to Figure 1 The first bracket 1 includes a guide portion 10 arranged along a first direction; the first adjustment structure 4 includes a sliding portion 40 and a first positioning member; wherein the sliding portion 40 is slidably connected to the guide portion 10, and the second bracket 2 is connected to the sliding portion 40; the first positioning member is used to position the sliding portion 40 on the guide portion 10.
[0048] In actual work, the sliding part 40 is slid along the layout direction of the guide part 10, so that the position of the second bracket 2 can be adjusted along the first direction, thereby adjusting the position of the positioning card plate 3 along the first direction. After adjusting to a suitable position, the sliding part 40 is positioned by the first positioning member to complete the adjustment of the positioning card plate 3 along the first direction.
[0049] There are a variety of selectable matching modes between the sliding portion 40 and the guiding portion 10, for example, a sliding rail and a sliding block, a guide rod and a sleeve, etc. can be used.
[0050] In this embodiment, the guide portion 10 includes a guide column, and the sliding portion 40 includes a guide sleeve, which is slidably sleeved on the guide column; the first positioning member can be a top screw, which is threadedly connected to the guide sleeve, and its end passes through the guide sleeve and abuts against the outer peripheral surface of the guide column to achieve positioning. Of course, in order to improve the sliding stability of the guide sleeve, the guide sleeve can be a ball sleeve.
[0051] Specifically, the cross-section of the guide column is a polygon, such as a rectangle, a pentagon, a hexagon, etc. The guide sleeve and the guide column are adapted to achieve polygonal matching, thereby constraining the guide sleeve in a first direction to prevent the guide sleeve from circumferential rotation.
[0052] Of course, the first adjustment structure 4 is not limited to the structures or methods listed above, and the first adjustment structure 4 of other structures can be used as long as it can achieve the position adjustment of the positioning clamping plate 3 along the first direction.
[0053] The second bracket 2 includes a connection portion 20 arranged along the second direction, and the second adjustment structure 5 includes a plurality of connection points arranged on the connection portion 20, and a connection member for connecting the positioning card plate 3 and the connection points; the plurality of connection points are arranged along the first direction. By changing the connection position of the positioning card plate 3 on the second bracket 2, the position of the positioning card plate 3 along the second direction can be adjusted.
[0054] Specifically, the connection point can be a connection hole; the connection piece can be a bolt, and the positioning clamp 3 is locked on the second bracket 2 by the bolt.
[0055] Likewise, the second adjustment structure 5 is not limited to the structures or methods listed above, and the second adjustment structure 5 with other structures can be used as long as it can adjust the position of the positioning clamping plate 3 along the second direction.
[0056] For example, in another embodiment, the second bracket 2 includes an adjustment rod arranged along the second direction, the adjustment rod includes a sleeved outer tube and an inner rod, the outer tube and the inner rod are slidably matched to form the above-mentioned second adjustment structure 5; one of the outer tube and the inner rod is connected to the first bracket 1, and the positioning clamp 3 is connected to the other. The second adjustment structure 5 also includes a second positioning member for positioning the relative position of the outer tube and the inner rod.
[0057] Specifically, the second positioning member includes a top screw, which passes through the outer tube and is tightly matched with the outer circumference of the inner rod to realize the positioning of the outer tube and the inner rod, thereby achieving the purpose of adjusting the positioning clamping plate 3 along the second direction.
[0058] For example, in another embodiment, the second adjustment structure 5 may also adopt mutually cooperating slide rails and sliders, guide rods and sleeves, etc.
[0059] The wind turbine blade mold provided by the present invention is described below. The wind turbine blade mold described below and the positioning tooling described above can be referred to each other.
[0060] Reference Figure 1 A wind turbine blade mold comprises a mold body 6 and the above-mentioned positioning tooling connected to the mold body 6.
[0061] Specifically, the mold body 6 is fixedly connected with a base 7 , and the first bracket 1 of the positioning tool is fixedly connected with the base 7 .
[0062] Specifically, the form of the base 7 can be standardized and shared with other tooling bases such as the main beam positioning tooling, the web positioning tooling, etc.
[0063] Specifically, the first bracket 1 and the base 7 of the positioning tool are fixed by a quick clamp 8 .
[0064] The novelty of the utility model lies in that: by installing the positioning tool on the blade mold, the positioning part of the positioning card plate 3 extends into the blade mold to locate the laying position of the auxiliary beam, and the blade mold is used as the positioning reference, so that the positioning reference is not affected by the thickness of the blade ply and the accuracy is higher; the first adjustment structure 4 can adjust the position of the second bracket 2 along the first direction, thereby adjusting the position of the card plate along the first direction, and the second adjustment structure 5 can adjust the position of the positioning card plate 3 along the second direction, thereby adjusting the position of the card plate along the second direction. Through the cooperation of the first adjustment structure 4 and the second adjustment structure 5, the positioning card plate 3 can be adjusted to any position within the plane formed by the first direction and the second direction, thereby improving the applicability and making the positioning tool applicable to the production of blades of different models.
