DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1:

[0023] Combine Figure 1The fan blade positioning welding device shown in the figure includes a welding base 1, which not only provides a stable support platform for the entire system, but also plays a role in supporting and fixing other mechanisms. The welding base 1 is provided with an expansion mechanism 2 for fixing the inner ring of the fan blade. Through the action of the expansion mechanism 2, it can adapt to the inner ring of the fan blade of a certain specification and accurately fix the inner ring of the fan blade firmly in the predetermined position, creating a stable working environment for the subsequent welding process. A support frame 3 is provided on one side of the welding base 1. The support frame 3 provides sufficient space and carrying capacity for subsequent mechanisms. A height adjustment mechanism 4 for realizing movement on the vertical plane is provided on the support frame 3, which enables the device to realize precise height adjustment on the vertical plane, thereby ensuring that the fan blade can be positioned during welding. Accurate positioning avoids welding errors caused by inconsistent height. The height adjustment mechanism 4 is provided with a position adjustment mechanism 5 that realizes movement on the horizontal plane. The function of the position adjustment mechanism 5 is to fine-tune the horizontal position of the blade according to the actual situation of the fan blade, so that the welding head can be accurately aligned with the welding point, avoiding welding quality problems caused by position deviation. The position adjustment mechanism 5 is provided with a fitting motor 6 to ensure that the fan blade can fit tightly to the inner ring of the fan blade and be stably fixed during the welding process. The telescopic rod of the fitting motor 6 is provided with a claw mechanism 7 for clamping the fan blade. The claw mechanism 7 firmly fixes the fan blade through clamping action, avoiding the displacement of the blade due to vibration or external force during the welding process, thereby ensuring the stability and reliability of the welding quality.

[0024] Combine Figure 2 The expansion mechanism 2 shown includes an expansion base 201 fixed to the upper surface of the welding base 1 and an expansion cylinder 202 fixed in the cavity of the welding base 1. The expansion base 201 is firmly connected to the welding base 1 by bolts. The expansion cylinder 202 is fixedly installed in the cavity of the welding base 1. As the core driving component of the expansion mechanism, its telescopic function enables the expansion process to be precisely controlled. The telescopic rod of the expansion cylinder 202 passes through the expansion base 201 and is provided with a first driving member 203. The extension and retraction of the telescopic rod of the expansion cylinder 202 is precisely controlled by the first driving member 203. The expansion base 201 Several groups of support members 204 are evenly distributed along the circumferential direction on the upper surface, and expansion claws 205 are rotatably arranged in the support members 204. A first linkage member 206 is rotatably arranged between the expansion claw 205 and the first driving member 203. This part is mainly controlled by the telescopic rod of the expansion cylinder 202 to control the up and down movement of the first driving member 203, and then drives the first linkage member 206 to drive the expansion claw 205 to move according to a predetermined trajectory and force, ensuring the efficiency and accuracy of the expansion process. Through this precise linkage structure, the expansion mechanism 2 can provide stable working performance for the inner rings of fan blades of different specifications.

[0025] The height adjustment mechanism 4 includes a screw rod 401 and a guide rod 402 which are respectively rotatably arranged on both sides of the support frame 3. The screw rod 401 is provided with a ball nut seat 403 which cooperates with it. The two realize the conversion of linear motion through close cooperation, and the ball nut seat 403 can move smoothly along its axis under the rotation of the screw rod 401. The guide rod 402 is provided with a guide block 404 which cooperates with it to ensure the effective operation of the ball nut seat 403 under the action of the height adjustment base plate 405 during the height adjustment process. A height adjustment base plate 405 is provided between the ball nut seat 403 and the guide block 404, wherein a height adjustment motor 406 which drives the rotation of the screw rod 401 is provided at the end thereof. This motor is responsible for driving the rotation of the screw rod 401. By precisely controlling the speed and rotation direction of the motor, fine adjustment of the height adjustment base plate 405 can be achieved.

[0026] The height adjustment base plate 405 is provided with a hollow groove 407 to provide space for the laminating motor 6 to move, thereby ensuring that the laminating motor 6 does not interfere with the height adjustment base plate 405 during the process of adjusting the horizontal position, thereby preventing collision and damage.

[0027] Combine Figure 3 The position adjustment mechanism 5 shown includes two sets of slide rails 501 relatively arranged on the height adjustment base plate 405, and sliders 502 are slidably arranged on both sets of slide rails 501. The layout of the slide rails 501 enables the sliders 502 to slide freely thereon, thereby providing a stable and smooth motion path. A position adjustment base plate 503 is arranged between the sliders 502, and the position adjustment base plate 503 is freely adjusted laterally through the sliding of the sliders 502. A position adjustment cylinder 504 is arranged on the height adjustment base plate 405, and the telescopic rod of the position adjustment cylinder 504 is fixedly connected to the position adjustment base plate 503. This arrangement can smoothly adjust the displacement of the position adjustment base plate 503 during the extension and retraction of the cylinder. The precise control of the cylinder can provide delicate thrust or pull according to needs, thereby ensuring that the movement of the base plate 503 on the slide rails 501 is more sensitive and error-free, and the fitting motor 6 is fixedly arranged on the position adjustment base plate 503.

[0028] Combine Figure 4The shown claw mechanism 7 includes a claw cylinder 701 fixedly arranged on the telescopic rod of the fitting motor 6, and two groups of clamping claws 702 are rotatably arranged on the side wall of the claw cylinder 701. The two groups of clamping claws 702 can be expanded or retracted at a specific position according to the telescopic action of the cylinder to form a clamping force, and ensure the fixation of the object by clamping it. A second driving member 703 is fixedly arranged on the telescopic rod of the claw cylinder 701, and a second linkage member 704 is rotatably arranged between the second driving member 703 and the clamping claw 702. This part drives the second driving member 703 through the claw cylinder 701 so that the second linkage member 704 transmits the power system to the clamping claw 702, thereby realizing the precise rotation and clamping or loosening action of the clamping claw 702, thereby ensuring the firm fixation of fan blades of different specifications and avoiding sliding or instability.
