Technical Field

[0001] This invention relates to the field of wind turbine guard production technology, and in particular to a welding fixture for wind turbine guards. Background Technology

[0002] A fan guard is a protective device installed at the air inlet or outlet of a fan. It typically uses a mesh structure design, which ensures both good ventilation and effective protection. It is mainly used to protect personnel safety and prevent foreign objects from entering the fan. The welding fixture for the fan guard is a special clamp and positioning device specifically designed for the welding process of the fan guard. Its core function is to accurately fix the frame, wire mesh and other components of the guard during the welding process, ensuring the relative position of each component is stable, thereby improving welding accuracy, consistency and production efficiency. It is a core auxiliary equipment for the mass production of fan guards.

[0003] Patent application number CN202211249146.0 describes in its specification that "This invention provides a welding fixture for an outer rotor mesh cover bracket, belonging to the technical field of wind turbine manufacturing equipment. It solves the technical problems of existing welding equipment being unable to weld circular outer rotor mesh covers and having low welding precision. The welding fixture for this outer rotor mesh cover bracket has an inner positioning ring fixed to a base plate, with an inner ring positioning groove and a mesh wire positioning protrusion on the inner positioning ring. A pressure plate is provided above the inner positioning ring, and a flat iron fixing block and an inner ring positioning post are installed on the lower side of the pressure plate.

This invention firmly fixes the circular mesh cover to be welded onto the welding equipment through the inner positioning ring, the outer positioning assembly, and the pressure plate, and the various components of the mesh cover will not shift during the welding process, which is beneficial to improving welding precision and welding efficiency."

[0004] While existing technical solutions have the advantages mentioned above, they also have disadvantages: wind turbine guards are generally composed of metal rings and long rods, and the main work involves welding the contact surfaces between the rings and the long rods. Existing technologies typically require workers to evenly place multiple long rods on the surface of the rings, and workers need to manually hold and limit the rods during welding.

[0054] 2. In use, the mold, groove, rotating rod, and protrusion are snapped together.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Example 1, such as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a welding fixture for a wind turbine mesh cover, comprising: a processing table 1 and a material unloading assembly.

[0068] The unloading assembly includes: a mounting frame 2, one end of which is fixedly mounted on the outer surface of the processing table 1. A placement box 4 is fixedly connected to the outer surface of the mounting frame 2. Multiple reinforcing wires 8 are movably installed on the inner wall of the placement box 4. A lifting frame 6 is vertically slidably arranged on the outer surface of the placement box 4. A limiting frame 9 is fixedly connected to the outer surface of the placement box 4. An L-shaped rod 5 is slidably connected to the outer surface of the limiting frame 9. When there is no obstruction at the bottom of the placement box 4, the reinforcing wires 8 fall from the bottom of the placement box 4 to the outside in sequence. The L-shaped rod 5 can move vertically in a straight line on the surface of the limiting frame 9.

[0069] It should be noted that two connecting rods 601 are rotatably installed on the inner wall of the lifting frame 6. A linkage rod 602 is rotatably provided at one end of each of the two connecting rods 601. A connecting rod 603 is rotatably connected to the inner wall of each of the two linkage rods 602. A moving plate 608 is rotatably provided on the outer surface of each of the two connecting rods 603. The outer surface of the L-shaped rod 5 is fixedly installed on the outer surface of the lifting frame 6. When the L-shaped rod 5 moves, it drives the lifting frame 6, connecting rods 601, linkage rods 602, and connecting rods 603 to move, so that the connecting rods 603 push the moving plate 608 to move linearly.

[0070] In addition, an anti-detachment pin 501 is fixedly installed on the outer surface of the L-shaped rod 5. The outer surface of the anti-detachment pin 501 is slidably connected to the inner wall of the limiting frame 9. A helical spring 502 is fixedly installed on the outer surface of the L-shaped rod 5. The other end of the helical spring 502 is fixedly installed on the outer surface of the limiting frame 9. Sliding strips 606 are slidably installed on the outer surfaces of the two moving plates 608. Limiting blocks 607 are fixedly connected to the outer surfaces of the two sliding strips 606. The outer surfaces of the two limiting blocks 607 are movably installed on the outer surface of one of the reinforcing wires 8. The limiting blocks 607 are used to block the reinforcing wires 8 in the box 4. The helical spring 502 is used to reset the L-shaped rod 5.

[0071] As examples, in this embodiment, two L-shaped plates 604 are fixedly arranged on the outer surface of the placement box 4. Each of the two L-shaped plates 604 has a limiting groove 605 on its outer surface. The outer surfaces of the two movable plates 608 are respectively slidably arranged on the inner walls of the two limiting grooves 605. Each of the two L-shaped plates 604 has an elastic sheet 609 fixedly arranged on its outer surface. The outer surfaces of the two sets of elastic sheets 609 are respectively fixedly installed on the outer surfaces of the two sliding bars 606. The elastic sheets 609 push the sliding bars 606 and the limiting block 607. The limiting groove 605 can limit the movement direction and amplitude of the movable plate 608.

[0072] In this embodiment, when the L-shaped rod 5 moves downward, it causes the spiral spring 502 to stretch, and at the same time, it causes the lifting frame 6, connecting rod one 601, linkage rod 602, and connecting rod two 603 to move downward in a straight line. This causes the connecting rod two 603 to push the moving plate 608 to move in a straight line within the limiting groove two 605, thereby causing the sliding strip 606 and the limiting block 607 to move away from the reinforcing wire 8. At the same time, it compresses the elastic sheet 609 to contract, which is beneficial for the reinforcing wire 8 to be fed out of the placement box 4.

[0073] Example 2, as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a welding fixture for a wind turbine mesh cover, comprising: a moving component.

[0074] It should be noted that the moving component includes: a threaded rod 101, both ends of which are mounted on the inner wall of the processing table 1 via bearings. A limit rod 102 is fixedly installed on the inner wall of the processing table 1. A servo motor 10 is fixedly installed at one end of the processing table 1. The output end of the servo motor 10 is fixedly connected to one end of the threaded rod 101. A moving block 103 is threadedly connected to the outer surface of the threaded rod 101. The inner wall of the moving block 103 is slidably disposed on the outer surface of the limit rod 102. When the servo motor 10 is working, it can drive the threaded rod 101 to rotate clockwise or counterclockwise, thereby driving the moving block 103 to reciprocate on the limit rod 102.

[0075] As an example, in this embodiment, the inner wall of the moving block 103 is fitted with a rotating rod 306 via a bearing. One end of the rotating rod 306 is fixedly provided with a plurality of protrusions 307. The outer surface of the rotating rod 306 is movably mounted with a mold 3. The outer surface of the mold 3 is provided with a plurality of grooves 304. The inner walls of the plurality of grooves 304 are respectively movably fitted onto the outer surfaces of the plurality of protrusions 307. When the moving block 103 moves, it drives the rotating rod 306, the protrusions 307, the mold 3 and the grooves 304 to move linearly.

[0076] In addition, multiple positioning blocks 301 are fixedly installed on the outer surface of the mold 3, and multiple sets of slots 302 are opened on the outer surface of the mold 3. Concentric rings 7 are movably installed on the inner wall of each set of slots 302. Limiting rings 303 are fixedly connected to the outer surface of the mold 3, and multiple hemispheres 305 are fixedly connected to the outer surface of the mold 3. The outer surface of the hemispheres 305 matches the outer surface of the L-shaped rod 5. By utilizing the weight of the mold 3 and the multiple concentric rings 7, it is easy to keep the hemispheres 305 from contacting the L-shaped rod 5 again, pressing the L-shaped rod 5 downward and moving it in a straight line, and the mold 3 will not move upward.

[0077] The other end of the rotating rod 306 is fixedly fitted with a worm gear 308, and the outer surface of the worm gear 308 is meshed with a worm 309. The two ends of the worm 309 are mounted on the inner wall of the moving block 103 through bearings. The outer surface of the moving block 103 is fixedly fitted with a drive motor 310, and the output end of the drive motor 310 is fixedly installed at one end of the worm 309. When the drive motor 310 is working, it drives the worm 309, the worm gear 308 and the rotating rod 306 to rotate.

[0078] In this embodiment, when the rotating rod 306 rotates, it drives the positioning block 301, protrusion 307, mold 3, slot 302, concentric ring 7, limiting ring 303, hemisphere 305, and groove 304 to rotate, thereby moving the positioning block 301 and hemisphere 305 directly below the placement box 4. The hemisphere 305 then presses the L-shaped rod 5 downwards, facilitating the feeding of the reinforcing wire 8 from the placement box 4 onto the surface of the concentric ring 7. Both ends of the reinforcing wire 8 are respectively restricted by the positioning block 301 and the limiting ring 303. Figure 4 As shown, this helps to improve the stability of the reinforcing wire 8 on the surface of the concentric ring 7, avoids the reinforcing wire 8 from shifting when the mold 3 is rotated to change the feeding position, facilitates automatic feeding, improves work efficiency, and reduces the labor intensity of workers.

[0079] Example 3, as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a welding fixture for a wind turbine mesh cover, comprising: a welding assembly.

[0080] The welding assembly includes two U-shaped frames 201. The outer surface of one U-shaped frame 201 is fixedly connected to the outer surface of the processing table 1, and the outer surface of the other U-shaped frame 201 is fixedly connected to the outer surface of the mounting frame 2. The outer surfaces of both U-shaped frames 201 are provided with limit grooves 202. The inner walls of the two limit grooves 202 are slidably connected with movable blocks 203. The outer surfaces of the two movable blocks 203 are fixedly provided with mounting plates 204. When the movable blocks 203 move linearly in the limit grooves 202, they drive the mounting plates 204 to move.

[0081] It should be noted that two movable rods 205 are slidably sleeved at both ends of the two mounting plates 204. Heat insulation plates 207 are fixedly connected to the outer surfaces of the two sets of movable rods 205. Two elastic elements 206 are fixedly connected to the outer surfaces of the two heat insulation plates 207. The other ends of the two sets of elastic elements 206 are respectively fixedly installed on the outer surfaces of the two mounting plates 204. When the mounting plates 204 move linearly, they drive the movable rods 205, elastic elements 206 and heat insulation plates 207 to move.

[0082] In addition, a pressure block 208 is fixedly installed on the outer surface of one of the heat insulation plates 207, and a flat electrode head 209 is fixedly installed on the outer surface of the other heat insulation plate 207. The flat electrode head 209 is connected to an external resistance spot welding machine via a cable. The outer surface of one of the movable blocks 203 is slidably mounted on the outer surface of the processing table 1, and the outer surface of the other movable block 203 is slidably mounted on the outer surface of the mounting frame 2. The outer surface of the flat electrode head 209 is in contact with the outer surface of the reinforcing wire 8, and the outer surface of the pressure block 208 is in contact with multiple concentric rings 7. When the heat insulation plate 207 moves, it drives the pressure block 208 and the flat electrode head 209 to move linearly. The pressure block 208 provides support for the concentric rings 7 and the reinforcing wire 8.

[0083] As examples, in this embodiment, two sets of semi-cylinders 210 are fixedly installed on the outer surfaces of the two U-shaped frames 201, and semi-cylinders 211 are fixedly installed on the outer surfaces of the two heat insulation plates 207. The semi-cylinders 211 cooperate with the two sets of semi-cylinders 210 respectively. Electric push rods 212 are fixedly installed on the outer surfaces of the two U-shaped frames 201. The output ends of the two electric push rods 212 are fixedly installed on the outer surfaces of the two movable blocks 203 respectively. The two electric push rods 212 work synchronously. When the electric push rods 212 work, they push the movable blocks 203 to move linearly.

[0084] In this embodiment, the second semi-cylinder 211 is initially located between the two first semi-cylinders 210. When the movable block 203 moves linearly, it drives the mounting plate 204, movable rod 205, elastic element 206, heat insulation plate 207, pressure block 208, and flat electrode head 209 to move. When the second semi-cylinder 211 and the first semi-cylinder 210 intersect, the second semi-cylinder 211 is pushed by the first semi-cylinder 210, thereby driving the heat insulation plate 207 to move linearly towards the concentric ring 7 and reinforcing wire 8. At the same time, it drives the elastic element 206 to stretch, thereby driving the pressure block 208 and the flat electrode head 209 to clamp the concentric ring 7 and reinforcing wire 8. At this time, the flat electrode head 209 is controlled to work to weld the reinforcing wire 8 and the concentric ring 7.

[0085] Working principle: When in use, connect the external power supply, and install the mold 3, groove 304, rotating rod 306, and protrusion 307. Then, the operator places multiple concentric rings 7 into multiple slots 302, and controls the servo motor 10 to drive the threaded rod 101 to rotate clockwise, thereby driving the moving block 103 to move linearly towards the placement box 4 on the limit rod 102. After the limit ring 303 of the mold 3 and the placement box 4 are on the same axis, control the servo motor 10 to stop working, and then control the drive motor 310 to work to drive the worm gear 3. 09. The worm gear 308 and the rotating rod 306 rotate, thereby driving the positioning block 301, the protrusion 307, the mold 3, the slot 302, the concentric ring 7, the limiting ring 303, the hemisphere 305, and the groove 304 to rotate. This rotates the positioning block 301 and the hemisphere 305 to directly below the placement box 4, and uses the hemisphere 305 to press the L-shaped rod 5 downward, which facilitates the feeding of the reinforcing wire 8 from the placement box 4 onto the surface of the concentric ring 7. The two ends of the reinforcing wire 8 are respectively limited by the positioning block 301 and the limiting ring 303. Figure 4As shown, this design improves the stability of the reinforcing wire 8 on the surface of the concentric ring 7, preventing the reinforcing wire 8 from shifting when the mold 3 is rotated to change the feeding position. It also facilitates automatic feeding, improves work efficiency, and reduces the workload of workers. When the reinforcing wire 8 moves directly below the flat electrode head 209, the output ends of the two electric push rods 212 drive the movable block 203 to move, causing the second semi-cylinder 211 to alternate with the two sets of first semi-cylinders 210. The second semi-cylinder 211 is initially positioned between the two first semi-cylinders 210. When the movable block 203 moves linearly, it drives the mounting plate 204 and the movable rod 205. The elastic element 206, heat insulation plate 207, pressure block 208, and flat electrode head 209 move. When the second semi-cylinder 211 and the first semi-cylinder 210 intersect, the second semi-cylinder 211 is pushed by the first semi-cylinder 210, thereby driving the heat insulation plate 207 to move linearly towards the concentric ring 7 and the reinforcing wire 8. At the same time, the elastic element 206 is stretched, which in turn drives the pressure block 208 and the flat electrode head 209 to clamp the concentric ring 7 and the reinforcing wire 8. At this time, the flat electrode head 209 is controlled to perform welding work on the reinforcing wire 8 and the concentric ring 7, which facilitates multi-position welding work and helps to improve the welding effect.
