For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1 to Figure 2 As shown, a positioning support mechanism for a modular blade midsection includes:

[0028] A support frame 1, which is used to support the workpiece of the middle section of the blade and is provided with three support parts 11, which are respectively located at the two ends and the middle end of the support frame 1;

[0029] The clamping mechanism 2 is relatively arranged at two ends of the support frame 1 and is located outside the support parts 11 at both ends, and is used to apply pressure to the workpiece in the middle section of the blade;

[0030] The support portion 11 includes a plurality of positioning shafts 11A and a plurality of support blocks 11B. The positioning shafts 11A fixedly connect the plurality of support blocks 11B. The support blocks 11B are arranged in a contour at the contact position with the workpiece of the middle section of the blade.

[0031] When using this positioning support mechanism, the middle section of the blade workpiece must first be suspended on the support frame 1. The support frame 1 is designed to include support parts 11 at three positions. These support parts 11 are located at both ends and the middle end of the support frame 1. Each support part 11 is composed of a number of positioning shafts 11A and support blocks 11B. The support blocks 11B are fixed together by the positioning shafts 11A. The shape is designed to match the contact surface of the middle section of the blade workpiece. Then the clamping mechanism 2 arranged at both ends of the support frame 1 starts to work, and the necessary pressure is applied to the middle section of the blade workpiece through the clamping block 21 to fix it in position. In the whole process, the clamping mechanism 2 can be adjusted to adapt to the specific needs of the middle section of the blade workpiece and ensure its correct position.

[0032] The positioning support mechanism ensures that the position of the blade middle section workpiece is stable during the entire plug-in assembly process, avoiding problems caused by displacement of the blade middle section workpiece or assembly errors. The contoured design of the support block 11B also makes the contact surface with the blade middle section workpiece more precise, reducing damage caused by poor contact, and the adjustable clamping mechanism 2 provides greater flexibility and can adapt to blade middle section workpieces of different specifications and shapes, which makes the operation more efficient and also helps to improve work efficiency and output quality.

[0033] As a preferred embodiment of the above, the clamping mechanism 2 is configured to be a flip opening and closing type, including a plurality of clamping blocks 21, a plurality of square tubes 22, a connecting shaft 23 and a driving member 24. The plurality of square tubes 22 fixedly connect the plurality of clamping blocks 21, the connecting shaft 23 is fixedly arranged at one end of the clamping block 21 close to the outside, and the driving member 24 is connected to the connecting shaft 23.

[0034] The connecting shaft 23 is caused to rotate by the driving member 24, and the rotation of the connecting shaft 23 is transmitted to the clamping block 21. The clamping block 21 is turned over due to the rotation of the connecting shaft 23, thereby contacting or leaving the workpiece in the middle section of the blade. The driving member 24 can also be controlled as needed to adjust the contact force and position of the clamping block 21 on the workpiece in the middle section of the blade, so as to achieve the installation and removal of the workpiece in the middle section of the blade. During the whole process, the action of the clamping mechanism 2 is controlled by the driving member 24 to ensure that the clamping block 21 is turned over at an appropriate speed and force to meet different operation requirements.

[0035] The clamping mechanism 2 is used to quickly and accurately process the workpiece in the middle section of the blade, making the assembly and disassembly process more convenient. The flipping and opening and closing method effectively controls the movement of the clamping block 21, thereby accurately applying or releasing pressure on the workpiece in the middle section of the blade, reducing the complexity and labor intensity of the operation, and increasing the scope of application and flexibility of the positioning support mechanism.

[0036] In this embodiment, the driving member 24 is a pneumatic cylinder or a hydraulic cylinder, a driving end 24A of the driving member 24 is rotatably connected to the connecting shaft 23 , and a fixed end 24B of the driving member 24 is connected to the supporting frame 1 .

[0037] When the air cylinder or hydraulic cylinder starts to work, the driving end 24A of the driving member 24 will generate power, thereby driving the connecting shaft 23 to rotate. The fixed end 24B of the driving member 24 is fixed on the supporting frame 1 to ensure stability.

[0038] In this embodiment, the support block 11B and the pressing block 21 on the same side of the support frame 1 are arranged in an arc shape, corresponding to the arc-shaped portion of the blade mid-section workpiece.

[0039] Since the support block 11B and the clamping block 21 are both designed to be arc-shaped, the arc-shaped structure corresponds to the arc-shaped portion of the workpiece in the middle section of the blade, ensuring the correct placement of the workpiece in the middle section of the blade. When the clamping mechanism 2 is working, the arc-shaped clamping block 21 will move along a predetermined direction and contact the arc-shaped portion of the workpiece in the middle section of the blade to achieve the clamping operation.

[0040] In this embodiment, a suction cup structure 3 is provided on the supporting parts 11 at both ends, and a suction cup structure 3 is also provided on the pressing mechanism 2;

[0041] The suction cup structure 3 is used to prevent displacement of the workpiece in the middle section of the blade when it is plugged in.

[0042] When the suction cup structure 3 is placed on the workpiece in the middle section of the blade, the suction cup structure 3 on the support part 11 will contact the surface of the workpiece in the middle section of the blade and form stable adsorption. Then, when the clamping mechanism 2 works, the suction cup structure 3 thereon further enhances the fixation of the workpiece in the middle section of the blade. During the whole process, the suction cup structure 3 can maintain the stable position of the workpiece in the middle section of the blade, thereby optimizing the docking quality of the workpiece in the middle section of the blade.

[0043] As a preference of the above embodiment, an adjuster 31 is provided on the suction cup structure 3 , and the adjuster 31 is used to adjust the angle of the suction cup structure 3 .

[0044] The regulator 31 enables the suction cup structure 3 to be adjusted to be completely aligned with the surface of the blade mid-section workpiece of any shape or size, and can be applied to a variety of different blade mid-section workpieces, thereby improving its versatility; by precisely adjusting the angle of the suction cup structure 3, the maximum area contact is ensured, thereby reducing the docking error and enhancing the quality and performance of the final blade; appropriate angle adjustment can enhance the gripping ability of the suction cup structure 3, maintain the stability of the blade mid-section workpiece during the processing, and avoid processing errors caused by position deviations.

[0045] In this embodiment, the blade middle section workpiece adopts four sets of positioning support mechanisms, and the first and fourth positioning support mechanisms are provided with initial guide devices 12, which are relatively arranged on both sides of the support frame 1 for preliminary positioning of the blade middle section workpiece.

[0046] The initial guide device 12 helps to initially position the workpiece in the middle section of the blade, ensures the correct position of the workpiece in the middle section of the blade, directly accelerates the subsequent docking and assembly steps, and improves production efficiency.

[0047] In this embodiment, the portion of the support portion 11 that contacts the workpiece at the middle section of the blade is covered with a rubber strip 11C.

[0048] The rubber strip 11C provides a soft contact surface, reducing the friction and wear that the support portion 11 may cause to the workpiece in the middle section of the blade, thereby extending the service life of the workpiece in the middle section of the blade and the durability of the support frame 1. The rubber also has a high friction coefficient, which can grip the workpiece in the middle section of the blade more firmly to prevent slipping and ensure the stability of the installation operation.

[0049] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
