Description

Technical Field

[0001] The utility model belongs to the technical field of cloth layer clamping, in particular to a leading edge cloth layer clamping tool. Background Art

[0002] With the development of the wind power industry, blade size and weight are rapidly increasing, and a variety of manufacturing process solutions are emerging. During the process of increasing blade size, to ensure the overall strength of the leading edge PET and BALSA areas, various specifications of uniaxial cloth are often added to the leading edge cloth layer to increase its overall strength. However, this can lead to many problems during production. For example, the uniaxial cloth tends to slide down after being turned over, forming wrinkles, and can easily accumulate as a whole, resulting in extensive rework. Currently, the uniaxial cloth is usually manually flattened and then pressed with a pressure block to prevent it from moving. When using a pressure block to secure the uniaxial cloth, when the other parts of the uniaxial cloth are then flattened, the pressure block may be pulled, causing the uniaxial cloth to misalign. Furthermore, workers working in the mold may accidentally touch the pressure block, causing it to move. Utility Model Content

[0003] The purpose of the utility model is to provide a leading edge cloth layer sandwiching tool to solve the problem that when the existing technology uses a pressing block to fix the uniaxial cloth, the pressing block may be pulled when other positions of the uniaxial cloth are flattened, causing the uniaxial cloth to be misplaced, and the worker may accidentally touch the pressing block when working in the mold, causing the pressing block to move.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a leading edge cloth layer clamping tooling, including a clamping frame, a mounting seat, a clamping pressure plate and a clamping elastic member, the clamping frame adopts a U-shaped frame, and the two sides of the clamping frame are respectively located on the inner and outer sides of one side of the mold; the mounting seat is fixed on the inner side of the clamping frame and close to the inner side of the mold; the clamping pressure plate is rotatably connected to the mounting seat; the clamping pressure plate clamps the cloth layer on the inner side of the mold under the elastic force of the clamping elastic member.

[0005] Furthermore, the middle portion of the clamping plate is configured as a deformable conforming plate, and the conforming plate is used to press against the inner side of the mold and conform to the inner side of the mold.

[0006] Furthermore, a force-bearing handle is fixed to the outer side of the clamping pressure plate.

[0007] Furthermore, a rotating shaft is rotatably connected to the mounting seat, and one side of the clamping pressure plate is fixed on the rotating shaft; the clamping elastic member adopts a torsion spring, and the clamping elastic member is fixed on the rotating shaft. One side of the clamping elastic member is connected to the force-bearing handle, and the other side can be against the side of the clamping frame close to the mounting seat.

[0008] The working principle of this technical solution is as follows: the side of the clamping frame away from the mounting seat is located outside the mold and closely adheres to the outside of the mold. The clamping pressure plate is pulled by the force-bearing handle and rotated to open the tooling. At this time, one side of the clamping elastic member is pressed against the inner side of the U-shaped frame. The clamping frame and the clamping pressure plate are then pressed down as a whole, so that the clamping plate is pressed down to the leading edge UD. By rotating the clamping plate in the opposite direction, the clamping plate is pressed against the fabric layer inside the mold, and the follower plate conforms to the shape of the inside of the mold. At the same time, the outside of the clamping frame and the clamping pressure plate also clamp the inner and outer sides of one side of the mold.

[0009] The beneficial effect of this technical solution lies in: by providing multiple fixtures to clamp fabric layers at multiple locations, effectively preventing them from sliding down. Furthermore, the entire fixture is clamped to the mold, eliminating the existing problems of fabric layer misalignment caused by movement. The conforming plate can conform to the internal shape of the mold, increasing the clamping area. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following is further described in detail through specific implementation methods:

[0013] The reference numerals in the drawings of the specification include: a clamping frame 1, a mounting seat 2, a clamping pressure plate 3, a force-bearing handle 4, a profile plate 5, a rotating shaft 6, and a clamping elastic member 7.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] The embodiment is basically as shown in the attached Figure 1-2As shown: The leading edge fabric layer clamping tooling includes a clamping frame 1, a mounting seat 2, a clamping pressure plate 3, and a clamping elastic member 7. The clamping frame 1 is a U-shaped frame, with its two sides located on the inner and outer sides of one side of the mold. The mounting seat 2 is fixed to the inner side of the clamping frame 1, close to the inner side of the mold. The mounting seat 2 can be composed of two sets of mounting plates arranged opposite and spaced apart. The clamping pressure plate 3 is rotatably connected to the mounting seat 2. Specifically, the mounting seat 2 is rotatably connected to a rotating shaft 6. One side of the clamping pressure plate 3 is fixed to the rotating shaft 6, and space is left between the two sets of mounting plates for the clamping pressure plate 3 to rotate. The clamping pressure plate 3 clamps the fabric layer inside the mold under the elastic force of the clamping elastic member 7. Specifically, the clamping elastic member 7 is a torsion spring and is fixed to the rotating shaft 6. The left side of the clamping elastic member 7 is connected to the force-bearing handle 4, and the right side can abut the side of the clamping frame 1 close to the mounting seat 2 (i.e., the right side of the clamping frame). The center of the clamping plate 3 is provided with a deformable conforming plate 5, which is used to press against the inside of the mold and conform to the mold's internal shape. The conforming plate 5 can be made of a deformable material or can be composed of several independent clamping blocks, with adjacent clamping blocks rotatably connected. A force-bearing handle 4 is fixed to the outside of the clamping plate 3.

[0016] The specific implementation process is as follows:

[0017] The left side of the clamping frame 1 is located outside the mold and is in close contact with the outside of the mold. The clamping plate 3 is pulled and rotated by the force-bearing handle 4 to open the tooling. At this time, the right side of the clamping elastic member 7 is pressed against the inner side of the clamping frame 1, generating a mutual force. The right side of the clamping frame 1 and the clamping plate 3 are then pressed downward as a whole, so that the clamping plate 3 is pressed down to the leading edge UD. By rotating the clamping plate 3 in the opposite direction, the clamping plate 3 is pressed against the fabric layer inside the mold, and the mold-forming plate 5 conforms to the shape of the inside of the mold. At the same time, the left side of the clamping frame 1 and the clamping plate 3 also clamp the inner and outer sides of one side of the mold.
