[0018] Please see Figures 1-5As shown, this utility model is a clamping structure for facilitating the processing of wind turbine blades. It includes a support assembly 11, which includes a worktable 111 providing a stable support foundation for the entire device. It also includes a processing mechanism 2 connected to the top of the worktable 111. The processing mechanism 2 assists in the processing operation. A blade body 113 is positioned above the worktable 111, and an auxiliary support 112 is mounted on the top of the worktable 111. The outer surface of the blade body 113 contacts the top of the auxiliary support 112. Moving devices 114 are installed on both the left and right sides inside the worktable 111.

Component 21 is connected to the output end of the moving device 114. The drive component 21 provides power output to the blade body 113. The clamping component 22 is connected to the drive component 21 and is driven by the drive component 21 to support and clamp the blade body 113.

The outer surface of the rotating cylinder 234 is welded to the side of several limit brackets 226 away from bracket 225. The starting motor 231 drives the driving gear 232 to rotate. The support frame 212 provides support for the motor. The driving gear 232 drives the driven gear 233 and the rotating cylinder 234 to rotate. The rotating cylinder 234 drives the clamping plate 221 to rotate through bracket 225 and support rod 222. The anti-slip side of the clamping plate 221 is in contact with the inner wall of the blade body 113, which can drive the blade body 113 to rotate together, facilitating multi-angle processing and realizing functional expansion.
[0019] A specific application of this embodiment is as follows: In use, the operator first uses a hoist to lift the blade body 113 onto the workbench 111 and place it on top of the auxiliary support 112. Then, the moving device 114 is activated according to the length of the blade body 113. When the moving device 114 is working, it will move the two support frames 212 away from or closer to each other to facilitate clamping and fixing the blade body 113. When the two support frames 212 are adjusted to a suitable position, the tail of the blade body 113 is first clamped and fixed by the hydraulic clamping device 115. Meanwhile, the hydraulic clamping device 115 clamps the flat part of the blade body 113. The contact point between the hydraulic clamping device 115 and the blade body 113 is flexible to reduce damage to the surface of the blade body 113. Then, the cylindrical part of the blade body 113 is clamped and fixed. Specifically, the cylindrical part of the blade body 113 is first fitted over several clamping plates 221, and then the electric push rod 211 is activated to drive the telescopic rod 213 to move. Simultaneously, the support frame 212 provides certain support for the electric push rod 211. During the movement of the telescopic rod 213, it slides inside the support frame 212 and the rotating cylinder 234. Simultaneously, the movement of the telescopic rod 213 causes the fixed ring 214 to move as well. When the fixed ring 214 moves, it drives several limiting brackets 223 to move together through the action of the rotating ring 224. At this time, the fixed ring 214 moves closer to the rotating cylinder 234. Simultaneously, the movement of the limiting brackets 223 through the fixed ring 214 drives several support rods 222 to move. During the movement of the support rods 222… The clamping plates 221 move away from each other through the action of the brackets 225, and are in an open state. Several brackets 225 rotate at fixed points inside several limiting brackets 226. As the clamping plates 221 move away from each other, they support and clamp the inner wall of the blade body 113. The blade body 113 is fixed by the internal support of several clamping plates 221. It can be applied to blade bodies 113 of various sizes, which improves the versatility of the equipment, makes it easy to flexibly adapt to the processing needs of different blades, and reduces the cost of equipment and maintenance difficulty. Simultaneously, during the processing of the blade body 113, the blade body 113 can also be rotated. Specifically, the starting motor 231 drives the drive gear 232 to rotate. During the rotation of the drive gear 232, the driven gear 233 will also rotate. The support frame 212 also provides a certain support force for the motor 231. During the rotation of the driven gear 233, the rotating drum 234 will rotate. At this time, during the rotation of the rotating drum 234, several brackets 225 and support rods 222 will drive several clamping plates 221 to rotate together. The side of the clamping plates 221 that is in contact with the inner wall of the blade body 113 is equipped with anti-slip features. When the clamping plates 221 rotate, The blade body 113 rotates together, facilitating multi-angle processing by the operator and expanding its functionality. During the rotation of the blade body 113, the hydraulic clamping device 115 rotates inside the support frame 212 on the right side. The auxiliary support 112 also provides a certain lifting effect for the blade body 113. During the rotation of the rotating drum 234, it rotates on the outer surface of the limiting ring 215 through the limiting groove 235. The interaction between the limiting groove 235 and the limiting ring 215 provides a certain degree of stability for the rotation of the rotating drum 234. During the rotation of the clamping plates 221, the rotating ring 224 rotates on the outer surface of the fixed ring 214 through the action of the support rods 222.
