[0029] Example

[0030] Reference Figures 1-4The utility model provides a technical solution: a plate welding device for the production and processing of a bracket for a wind turbine hub, comprising a support base 1 and a grinding mechanism 3, and a positioning frame 2 is fixedly installed on the upper surface of the support base 1, the grinding mechanism 3 comprises a first mechanical arm 31, the first mechanical arm 31 is installed on the support base 1, a rotating disk 311 is installed on one end of the first mechanical arm 31, a control motor 32 is installed on the upper surface of the rotating disk 311, a rotating shaft 321 is fixedly installed on the output end of the control motor 32, a grinding disk 33 is fixedly installed on one end of the rotating shaft 321, a positioning plate 34 is fixedly installed on the outer surface of the rotating disk 311, and a receiving plate 341 is slidably installed inside the positioning plate 34.

[0031] In a preferred embodiment, the outside of the positioning frame 2 is fixedly installed with a connecting seat 4, and the upper surface of the connecting seat 4 is fixed with an electric telescopic rod 5. A sliding groove 6 is provided on one side of the positioning frame 2. The telescopic end of the electric telescopic rod 5 is fixedly connected to the connecting block 7, and one side of the connecting block 7 is rotated to connect the circular plate 8. In order to facilitate the welding of the plate, this device uses the electric telescopic rod 5 to push the connecting block 7 to move downward, thereby controlling the downward movement of the plate, and the connection between the two plates can be welded by the welding machine 11, and a sliding groove 6 is provided on the positioning frame 2 to extend the moving distance of the connecting block 7, and the circular plate 8 is rotatably installed on one side of the connecting block 7 to control the flipping of the plate so that the other side of the plate can be welded.

[0032] In a preferred embodiment, a second robotic arm 9 is installed on the upper surface of the support base 1, a rotatable disc 10 is installed at the end of the second robotic arm 9, and a welding machine 11 is fixedly connected to the upper surface of the disc 10. In order to realize automatic welding, a second robotic arm 9 is installed on the support base 1, a disc 10 is installed on the second robotic arm 9, and a welding machine 11 is installed on the disc 10. Through the operation of the second robotic arm 9, the welding machine 11 can weld the connection between the two plates to meet the processing requirements.

[0033] To ensure stable processing of the plate, a fixed plate 12 is fixedly installed on one side of the circular plate 8, and a slidable clamping plate 13 is also provided on one side of the circular plate 8. A horizontal plate is fixedly installed on the outer surface of the circular plate 8, and the internal thread of the horizontal plate is connected to the screw 14. One end of the screw 14 is rotatably connected to the clamping plate 13. One side of the plate is placed between the clamping plate 13 and the fixed plate 12, and then the screw 14 is turned to rotate and push the clamping plate 13 to move, so that the clamping plate 13 squeezes the plate, and the plate can be positioned to achieve stable processing of the plate.

[0034] This device controls the plate to move downward so that the welding machine 11 welds the joints of the plate. In order to ensure that the plate moves downward stably, a limiting mechanism 15 is installed on the positioning frame 2. The limiting mechanism 15 includes a positioning block 151 and a limiting rod 152. The positioning block 151 is fixedly installed on one side of the positioning frame 2, and the limiting rod 152 is fixedly installed on the upper surface of the positioning block 151. The rectangular plate 16 is fixedly installed on the outer side of the circular plate 8. Through holes 17 are respectively opened in the interior of the rectangular plate 16 and the connecting block 7, and the limiting rod 152 is slidably connected to the inside of the through hole 17.

[0035] In actual use, after the plate is positioned, the telescopic end of the electric telescopic rod 5 is used to push the connecting block 7 to move downward. As the connecting block 7 moves downward, the limiting rod 152 will extend into the interior of the connecting block 7, and the limiting rod 152 will also pass through the interior of the rectangular plate 16, thereby limiting the connecting block 7 and the rectangular plate 16, so that the connecting block 7 drives the rectangular plate 16 and the circular plate 8 to move downward, thereby controlling the stable downward movement of the plate to prevent the plate from shaking with the circular plate 8 and affecting processing.

[0036] Specifically, the working process or working principle of a plate welding device for producing and processing a bracket for a wind turbine hub is as follows: the bracket of the hub is welded together by multiple processed plates to form a bracket, and these plates are generally positioned during welding, and the welding points of the plates are tightly fitted together, and then welded by a welding robot to improve work efficiency. During welding, it was found that even if a welding robot is used to weld the welding points, welding slag will be generated, and the generation of welding slag will affect the flatness of the outer surface of the product. Therefore, the product is currently removed after welding and the welding points are polished. Such operation increases the welding steps, wastes time, and reduces work efficiency, so this device is designed to solve this problem.

[0037] The present invention can simultaneously weld the plates and grind the welded joints, and there is no need to wait for the plates to be completely welded before grinding them, which saves processing procedures, saves time and improves work efficiency. The specific operation is as follows: connect the external power supply, install the two plates to be welded between the fixed plate 12 and the clamping plate 13 respectively, and the clamping plate 13 is pushed to move by turning the screw 14, so that the clamping plate 13 moves toward the position of the fixed plate 12, thereby clamping the plates and tightly fitting the end faces of the two plates together. Then, the electric telescopic rod 5 is opened, and the telescopic end of the electric telescopic rod 5 pushes the connecting block 7 downward. As the connecting block 7 moves downward, the limiting rod 152 extends into the interior of the connecting block 7, and the limiting rod 152 also passes through the interior of the rectangular plate 16, thereby limiting the connecting block 7 and the rectangular plate 16, so that the connecting block 7 drives the rectangular plate 16 and the circular plate 8 to move downward, thereby controlling the stable downward movement of the plates.

[0038] When the plate moves to the position of the welding machine 11, the second robotic arm 9 rotates to make the welding machine 11 correspond to the welding position, and the welding machine 11 welds the plate connection. At the same time, the plate will continue to move downward, and the electric telescopic rod 5 slowly pushes the plate downward so that the welding machine 11 can weld other positions of the plate. The welded position will move downward and pass the position of the welding machine 11. At this time, the first robotic arm 31 can be used to control the grinding disc 33 to be attached to the welding position, and the motor 32 is controlled to drive the grinding disc 33 to rotate so that the grinding disc 33 grinds the welding position, grinds off the welding slag, and keeps the welding position flat so that subsequent products can be used normally.

[0039] In this way, the joints of the plates can be welded and polished at the same time, which saves welding steps and improves work efficiency. When the welding of one side of the plate is completed, the other side needs to be welded. At this time, the electric telescopic rod 5 pulls the plate upward and disengages the limit rod 152 from the inside of the connecting block 7. Then the circular plate 8 is rotated to flip the other side of the plate to the welding position, and the plate is continued to be welded according to the above-mentioned welding method. While welding, the position of the welding point can still be polished by the grinding disc 33, which is convenient for operation.

[0040] In the process of grinding the plate by the grinding disc 33, in order to prevent the powder from falling onto the support seat 1 and affecting the processing environment, when the grinding disc 33 contacts the outer surface of the plate, one side of the receiving plate 341 will also contact the outer surface of the plate. The powder generated by the grinding disc 33 during the grinding process will fall onto the receiving plate 341. The device is equipped with a spring inside the positioning plate 34, and the spring is fixedly connected to the receiving plate 341, so that the receiving plate 341 can be tightly attached to the outer surface of the plate under the action of the spring, thereby receiving the powder to meet the processing needs.

[0041] It should be noted that the first robotic arm 31, the control motor 32, the electric telescopic rod 5 and the second robotic arm 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
