[0044] Figure 2 This is a schematic diagram of the structure of the tangential positioning and pressurizing device for the UD web of a wind turbine blade provided in an embodiment of the present invention; Figure 3 Show Figure 2 A magnified view of a section marked A in the middle; Figure 4 Show Figure 2 A magnified view of a section marked B in the middle; Figure 5 This is a front view of the tangential positioning and pressurizing device for the UD web of a wind turbine blade provided in an embodiment of the present invention; Figure 6 This is a top view of the chordal positioning and pressurizing device for the UD web of a wind turbine blade provided in an embodiment of the present invention; Figure 7 This image shows a side view of the chordal positioning and pressurizing device for the UD web of a wind turbine blade provided in an embodiment of the present invention. (Refer to...) Figures 2-7 This embodiment provides a chordal positioning and pressurizing device for the web of a wind turbine blade (UD). The chordal positioning and pressurizing device for the web of a wind turbine blade (UD) includes a pressurizing fixture frame 100, a positioning rod 200, a swing arm mechanism 300, and a pressing mechanism 400.

[0045] Specifically, the positioning rod 200 is fixedly disposed on one side of the bottom of the pressure fixture frame 100. The swing arm mechanism 300 includes a swing arm body 310 and a positioning component 320. The swing arm body 310 is rotatably disposed on the other side of the bottom of the pressure fixture frame 100 and is arranged opposite to and spaced apart from the positioning rod 200. The UD web plate 10 is located between the swing arm body 310 and the positioning rod 200. The positioning component 320 is disposed at the connection between the swing arm body 310 and the pressure fixture frame 100, and can lock and position the swing arm body 310 so that the swing arm body 310 is in a first position and fixed relative to the pressure fixture frame 100, which facilitates the subsequent pressing and positioning process of the UD web plate 10. The positioning component 320 can also unlock the swing arm body 310, allowing the swing arm body 310 to swing relative to the pressurizing fixture frame 100 to a second position. This facilitates the separation of the UD web 10 from the chordal positioning and pressurizing device of the wind turbine blade UD web. Figure 7 As shown.

[0046] More specifically, the pressing mechanism 400 is disposed on the swing arm body 310. The pressing mechanism 400 can press the UD web 10 against the positioning rod 200. The distance between the pressing end of the pressing mechanism 400 and the positioning rod 200 can be adjusted to adapt to the positioning of the UD web 10 and the positioning rod 200 with different thicknesses, and to facilitate the application of pressure to press the UD web 10 tightly.

[0047] More specifically, the swing arm body 310 is provided with a plurality of pressing mechanisms 400 at intervals along its length. By using the plurality of pressing mechanisms 400 to press the UD web 10 against the positioning rod 200, the uniformity of force on the UD web 10 can be improved in the length direction of the positioning rod 200, and the reliability of the positioning of the UD web 10 can be improved.

[0048] More specifically, there are multiple positioning rods 200, which are arranged parallel to each other and spaced apart, all located on the same side of the bottom of the pressure fixture frame 100. There are also multiple swing arm mechanisms 300, each corresponding to a positioning rod 200, located on the other side of the bottom of the pressure fixture frame 100. By providing multiple swing arm mechanisms 300, multiple pressing mechanisms 400 arranged in an array can be formed to press against the UD web 10, improving the uniformity of force on the UD web 10 in the direction of the spaced positioning rods 200, thereby further improving the reliability of the UD web 10's positioning.

[0049] Reference Figure 2 and Figure 3The positioning assembly 320 includes a positioning plate 321 and a positioning bolt 322. The positioning plate 321 is provided on both sides of the swing arm body 310. The positioning plate 321 has positioning holes, and the positioning bolt 322 is detachably inserted into the positioning holes to press and lock the swing arm body 310 against the pressure fixture frame 100. When the positioning bolt 322 is pulled out of the positioning hole, the swing arm body 310 is in a free state and can swing relative to the pressure fixture frame 100.

[0050] Specifically, the swing arm mechanism 300 further includes a rotating connecting plate 330 and a rotating connecting column 340. The rotating connecting plate 330 is disposed on the pressure fixture frame 100, and the rotating connecting plate 330 is respectively disposed on both sides of the swing arm body 310. The rotating connecting column 340 passes through the swing arm body 310 and the rotating connecting plate 330, and the swing arm body 310 can rotate about the rotating connecting column 340 as an axis.

[0051] Figure 8 This diagram illustrates the structure of the limiting bushing provided in an embodiment of the present invention. Figure 9 A schematic diagram of the structure of the pressure bar provided in an embodiment of the present invention is shown. (Refer to...) Figure 2 and Figures 7-9 The pressing mechanism 400 includes a limiting bushing 410 and a pressing rod 420. The limiting bushing 410 is fixedly connected to the side of the swing arm body 310 facing the positioning rod 200 by welding. A limiting block 411 protrudes from the inner wall of the limiting bushing 410. The pressing rod 420 has an elongated limiting groove 421 along the axial direction. The pressing rod 420 passes through the limiting bushing 410, and the limiting block 411 is slidably accommodated in the limiting groove 421. The pressing rod 420 can move axially along the limiting bushing 410 to abut against or move away from the UD web 10.

[0052] Figure 10 A schematic diagram of the internally threaded tube provided in an embodiment of the present invention is shown. (Refer to...) Figure 2 , Figure 9 and Figure 10 The pressing mechanism 400 also includes an internally threaded tube 430. The swing arm body 310 has a through hole in the radial direction, through which the internally threaded tube 430 movably passes and coaxially inserts into the limiting sleeve 410. The internally threaded tube 430 is rotatable relative to the limiting sleeve 410. The pressing rod 420 has an external thread and is screwed into the internally threaded tube 430. Driven by the rotation of the internally threaded tube 430 and limited by the limiting sleeve 410, the pressing rod 420 moves along the axial direction of the limiting sleeve 410.

[0053] Figure 11A schematic diagram of the rotating handwheel provided in an embodiment of the present invention is shown. (Refer to...) Figure 4 , Figure 10 and Figure 11 The pressing mechanism 400 also includes a rotary handwheel 440. The rotary handwheel 440 is located on the side of the swing arm body 310 opposite to the limiting bushing 410 and is coaxially connected to the internally threaded tube 430. The internally threaded tube 430 can rotate under the drive of the rotary handwheel 440. Specifically, the rotary handwheel 440 includes a turntable 441 and a handle 442. The internally threaded tube 430 is fixed to the geometric center of the turntable 441, and the handle 442 is located at the maximum diameter of the turntable 441, facilitating rotation by the operator to provide a larger rotational torque and reduce the operator's workload.

[0054] Specifically, such as Figure 10 As shown, a snap-fit ​​block 431 is provided on the circumferential side of the end of the internally threaded pipe 430. There are two snap-fit ​​blocks 431, which are arranged opposite to each other and are integrally formed on the circumferential side of the end of the internally threaded pipe 430. Figure 11 As shown, a through hole is provided at the geometric center of the turntable 441, and corresponding snap-fit ​​grooves 443 are provided on the inner wall of the through hole. The snap-fit ​​blocks 431 are snapped into the snap-fit ​​grooves 443 in a one-to-one manner to achieve coaxial positioning of the internal threaded tube 430 and the turntable 441. A portion of the internal threaded tube 430 protrudes through the aforementioned through hole to the side of the turntable 441 opposite to the swing arm body 310, and is secured with a nut 432, thereby achieving a reliable fixed connection between the internal threaded tube 430 and the turntable 441.

[0055] Continue to refer to Figure 2 and Figure 4 The pressing mechanism 400 further includes a pressing head 450, which is disposed at the pressing end of the pressing rod 420 and can abut against the UD web 10. The cross-sectional area of ​​the pressing head 450 is larger than that of the pressing rod 420. The pressing head 450 increases the contact area with the UD web 10, thereby improving the pressing reliability of the pressing mechanism 400 against the UD web 10.

[0056] Specifically, the angle between the pressing end of the pressing head 450 and the axis of the pressing rod 420 is adjustable. In this embodiment, the ends of the pressing head 450 and the pressing rod 420 can be connected by a ball joint connector to achieve universal adjustment of the pressing head 450 relative to the pressing rod 420. This configuration increases the flexibility of the pressing mechanism 400, facilitating the pressing of the UD web 10 with different surface structures.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
