[0002] Wind energy is one of the pollution-free energy sources, and it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas with water shortage, fuel shortage and inconvenient transportation, it is very suitable and has great potential to be used for wind power generation in accordance with local conditions.

[0020] S1: The worker places the workpiece to be welded on the surface of the placement table, and then activates the electric telescopic rod to make the workpiece contact the thickness measuring plate, causing the rotating disk to rotate;

[0021] S2: The rotation of the rotating disk causes the mounting block to move inside the first sliding groove, thereby clamping and fixing the weldment. The distance between the two weldments is adjusted according to the thickness of the weldment.

[0022] S3: Start the motor, the motor drives the crankshaft to rotate, and then drives the L-shaped plate to rotate, thereby driving the connecting rod to reciprocate, and the reciprocating motion of the connecting rod drives the second threaded cylinder to reciprocate, thereby rotating the gear rod, and then the welding head to reciprocate;

[0023] S4: When the thickness of the two welded parts changes from the previous thickness, the weld between the two welded parts changes, and the first rotating rod rotates as the weld changes, thereby changing the amplitude of the up and down reciprocating motion of the second threaded rod, thereby changing the rotation amplitude of the rack rod, and thus the weld can be completely filled with solder;

[0025] The invention provides a flame welding device for wind power components, which has the following beneficial effects:

[0026] 1. Through the setting of the welding positioning mechanism, the width of the weld can be adjusted according to the thickness of the welded parts. The small gap of the thick plate makes the amount of filler metal required during welding relatively small, thereby reducing the heat input during welding, and then effectively controlling the welding deformation, improving the dimensional accuracy and stability of the welded structure. The larger weld between thin plates can provide a more complete and continuous seal, reduce the porosity and defects in the weld, thereby reducing the possibility of corrosive media entering the weld, reducing corrosion channels, and improving the corrosion resistance of the welded structure.

[0027] 2. Through the setting of the welding swing mechanism, the swing amplitude of the welding head can be adjusted according to the size of the weld. By automatically adjusting the swing amplitude, the welding trajectory can be accurately controlled according to the size of the weld, making the shape of the weld more uniform and beautiful, and the weld height and width can be kept within a reasonable range, reducing the unevenness and uneven width of the weld surface, and improving the welding appearance quality.

[0028] 3. Through the setting of the solder control mechanism, the delivery amount of solder can be controlled. A reasonable amount of solder can avoid various defects caused by too much or too little solder. Too much solder may cause overflow, affect the appearance of the weldment, and may also cause stress concentration during the cooling process; too little solder cannot fill the weld, resulting in insufficient strength. By accurately controlling the amount of solder according to the size of the weld, these defects can be effectively reduced and the welding quality can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0042] Reference Figures 1-10The present technical solution provides a flame welding device for wind power components, which specifically includes a platform 1. A welding positioning mechanism 2 is installed on the top of the platform 1. The welding positioning mechanism 2 includes a vertical plate 201, a placement table 203, a first pulley 205 and a first sliding groove 207. The vertical plate 201 is installed on the side of the platform 1. There are multiple vertical plates 201. A first electric track 202 is installed between the multiple vertical plates 201. The placement table 203 is fixedly installed on the top of the platform 1. A welding piece 204 is placed on the top of the placement table 203. The first pulley 205 is rotatably installed on the top of the platform 1. There are two first pulleys 205. A rotating disk 206 is fixedly installed on the top of the two first pulleys 205. The first sliding groove 207 is opened on the platform 1, a plurality of first sliding grooves 207 are provided, and a mounting block 208 is slidably installed inside each of the plurality of first sliding grooves 207, a lever 209 is fixedly installed on the top of the mounting block 208, a second sliding groove 210 is provided on the surface of the rotating disk 206, the lever 209 is slidably connected to the second sliding groove 210, an electric telescopic rod 211 is fixedly installed on the side of the mounting block 208, and a push plate 212 is fixedly installed on the telescopic end of the electric telescopic rod 211, a side plate 213 is fixedly installed on the top of the placing table 203, a plurality of side plates 213 are provided, a third sliding groove 214 is provided on the surface of the left side plate 213, a sliding block 215 is slidably installed inside the third sliding groove 214, and a sliding rod 211 is fixedly installed inside the third sliding groove 214 6. The sliding block 215 is slidably connected to the sliding rod 216. The bottom of the placement table 203 is rotatably installed with a first threaded cylinder 217. The bottom of the sliding block 215 is fixedly installed with a first threaded rod 218. The first threaded rod 218 is threadedly connected to the first threaded cylinder 217. The bottom of the first threaded cylinder 217 is fixedly installed with a second pulley 219. The second pulley 219 is connected to the first pulley 205 through a belt. A thickness measuring plate 220 is installed on the side of the sliding block 215. When the staff places the weldment 204 to be welded on the placement table 203, the electric telescopic rod 211 is started. The electric telescopic rod 211 can push the weldment 204 to move on the placement table 203. When the weldment 204 moves to the thickness measuring plate 220, When the welded part 204 is in the correct position, the thickness measuring plate 220 moves according to the thickness of the welded part 204, thereby causing the sliding block 215 to slide inside the third sliding groove 214. The sliding of the sliding block 215 can compress the second spring 221. At the same time, the movement of the sliding block 215 can drive the first threaded rod 218 to move inside the first threaded cylinder 217, thereby driving the first threaded cylinder 217 to rotate. The rotation of the first threaded cylinder 217 can drive the second pulley 219 to rotate, thereby driving the first pulley 205 to rotate. The rotation of the first pulley 205 can drive the rotating disk 206 to rotate. The rotation of the rotating disk 206 can cause the mounting block 208 to move inside the first sliding groove 207.The rotation of the rotating disk 206 can make the lever 209 slide inside the second sliding groove 210, so that the mounting block 208 can slide inside the first sliding groove 207. When the two mounting blocks 208 move toward the center of the circle close to the rotating disk 206, the two mounting blocks 208 can push both sides of the welding part 204 to move the welding part 204. When the other side of the welding part 204 contacts the side plate 213, the left and right sides of the welding part 204 can be limited, so that the welding part 204 can be clamped and positioned, and the gap between the two welding parts 204 can be adjusted according to the thickness of the welding parts 204, so that the gap between the two thicker welding parts 204 can be Smaller gaps between thick plates mean smaller welds, which in turn require less filler metal, thus reducing heat input during welding. With reduced heat input, the thermal expansion and contraction of thick plates during welding are relatively small, effectively controlling welding deformation and improving the dimensional accuracy and stability of the welded structure. Larger welds between thin plates provide a more complete and continuous seal, reducing pores and defects in the welds, thereby reducing the possibility of corrosive media entering the welds, reducing corrosion channels, and improving the corrosion resistance of the welded structure. The weld interval range set for the entire device complies with the regulations, and there will be no welds that are too large or too small.

[0043] Reference Figures 1-10, This embodiment also proposes that a welding swing mechanism 3 is installed on the top of the platform 1, and the welding swing mechanism 3 includes a support plate 301, which is fixedly installed on the top of the platform 1, and there are two support plates 301.

The surface of the slide column 303 is fixedly installed with a limit plate 304. The surface of the slide column 303 is sleeved with a first spring 305. The first spring 305 is arranged between the limit plate 304 and the side plate 213. The surface of the first electric rail 202 is slidably installed with a second electric rail 306. The surface of the second electric rail 306 is slidably installed with a mounting member 307. The bottom of the mounting member 307 is rotatably installed with a welding head 308. The bottom of the second electric rail 306 is fixedly installed with a mounting seat 309. The mounting seat 309 is set There are two, a gear rod 310 is rotatably installed between the two mounting seats 309, the gear rod 310 is rotatably connected to the mounting member 307, and the gear rod 310 is engaged with the welding head 308. Through the setting of the gear rod 310, when the gear rod 310 rotates, the rotating gear rod 310 can drive the welding head 308 to rotate together, and when the mounting member 307 slides on the surface of the second electric track 306, the welding head 308 can also slide on the surface of the gear rod 310, thereby realizing welding. The joint 308 swings and rotates while moving laterally, so as to achieve filling and welding of the weld. The surface of the left support plate 301 is rotatably installed with a first gear 311, and the end of the sliding column 303 is fixedly installed with a first tooth plate 312. The first tooth plate 312 is engaged with the first gear 311. When the moving welding part 204 squeezes the first tooth plate 312, the first tooth plate 312 can be moved, and the movement of the first tooth plate 312 can drive the first gear 311 to rotate.

[0044] Reference Figures 1-10The present embodiment further proposes that a mounting plate 313 is fixedly installed on the side of the support plate 301, and two mounting plates 313 are provided. A second tooth plate 314 is slidably installed on the surface of the two mounting plates 313, and a third tooth plate 315 is fixedly installed on the bottom of the second tooth plate 314. A rotating shaft 316 is fixedly installed on the side of the first gear 311, and a second gear 317 is fixedly installed on the surface of the rotating shaft 316. The second gear 317 is meshed with the third tooth plate 315. When the first gear 311 rotates, the rotating shaft 316 can be driven to rotate. The rotating rotating shaft 316 can drive the second gear 317 to rotate, thereby causing the third tooth plate 315 to move. The movement of the third tooth plate 315 can drive the second tooth plate 314 to move. The third gear 318 is rotatably installed on the side of the mounting plate 313, and the third gear 318 is meshed with the second gear plate 314. When the second gear plate 314 moves, the third gear 318 can be driven to rotate. A first rotating rod 319 is rotatably installed between the two mounting plates 313. The first rotating rod 319 is fixedly connected to the third gear 318. A circular plate 320 is fixedly installed on the surface of the first rotating rod 319. When the third gear 318 rotates, the first rotating rod 319 can be driven to rotate. The circular plate 320 is connected to the eccentric part of the first rotating rod 319. Therefore, when the first rotating rod 319 rotates, the circular plate 320 can be driven to rotate eccentrically. A rotating plate 321 is rotatably installed on the surface of the circular plate 320. When the circular plate 320 rotates, it can drive the rotating plate 321 to rotate. The crankshaft 322 is rotatably installed inside the two mounting plates 313. The L-shaped plate 323 is rotatably installed inside the crankshaft 322. The L-shaped plate 323 is rotatably connected to the rotating plate 321. The other end of the L-shaped plate 323 is rotatably installed with a connecting rod 324. The end of the connecting rod 324 is rotatably installed with a second threaded rod 325. The side of the support plate 301 is fixedly installed with a fixing seat 326. The top of the fixing seat 326 is rotatably installed with a second threaded cylinder 327. The second threaded rod 325 is threadedly connected to the second threaded cylinder 327. The top of the second threaded cylinder 327 is fixedly installed with a first bevel gear 328. The side of the support plate 301 is rotatably installed with a second bevel gear 329. The second bevel gear 329 is rotatably installed. 29 is meshed with the first bevel gear 328, and the second bevel gear 329 is connected to the gear rod 310 through a belt. A motor 330 is fixedly installed inside the placement table 203, and the motor 330 is connected to the crankshaft 322 through a belt. When the motor 330 is started, it can drive the crankshaft 322 to rotate, and then drive the L-shaped plate 323 to rotate, and then drive the connecting rod 324 to reciprocate up and down. The reciprocating motion of the connecting rod 324 can drive the second threaded rod 325 to move up and down, so that the second threaded cylinder 327 can reciprocate, and the reciprocating rotation of the second threaded cylinder 327 can drive the first bevel gear 328 to rotate, and the rotation of the first bevel gear 328 can drive the second bevel gear 329 to rotate.This can drive the gear rod 310 to rotate back and forth. Through the arrangement of the first rotating rod 319, when the distance between the two welded parts 204 changes, the first rotating rod 319 rotates, which in turn rotates the rotating plate 321. This changes the amplitude of the reciprocating movement of the second threaded rod 325, and thus the rotation amplitude of the gear rod 310. This allows the weld to be completely filled. By automatically adjusting the swing amplitude, the welding trajectory can be precisely controlled according to the size of the weld, making the weld shape more uniform and beautiful. The weld reinforcement height and width can be kept within a reasonable range, reducing unevenness and unevenness on the weld surface, and improving the weld appearance quality.

[0045] Reference Figures 1-10 , This embodiment also proposes that a solder control mechanism 4 is installed on the side of the right support plate 301, and the solder control mechanism 4 includes a fourth gear 401, which is rotatably installed on the side of the right support plate 301. The fourth gear 401 is engaged with the first tooth plate 312, so when the first tooth plate 312 moves, it can drive the fourth gear 401 to rotate. The side of the fourth gear 401 is fixedly installed with a third bevel gear 402, and the side of the right support plate 301 is fixedly installed with a horizontal plate 403, the bottom of the horizontal plate 403 is rotatably mounted with a third threaded cylinder 404, the bottom of the third threaded cylinder 404 is fixedly mounted with a fourth bevel gear 405, the fourth bevel gear 405 is meshed with the third bevel gear 402, the internal thread of the third threaded cylinder 404 is mounted with a third threaded rod 406, the top of the third threaded rod 406 is fixedly mounted with a baffle plate 407, the side of the right support plate 301 is fixedly mounted with a control box 408, the baffle plate 407 is slidably connected to the control box 408, the welding head 3 The side of 08 is fixedly installed with a delivery pipe 409, and the welding head 308 is connected to the storage tank 302 through the delivery pipe 409. When the fourth gear 401 rotates, the rotating fourth gear 401 can drive the third bevel gear 402 to rotate, and the rotating third bevel gear 402 can drive the fourth bevel gear 405 to rotate, and the rotation of the fourth bevel gear 405 can drive the third threaded cylinder 404 to rotate, thereby making the third threaded rod 406 reciprocate up and down inside the third threaded cylinder 404, thereby driving the baffle plate 407 to slide inside the control box 408, so as to control the delivery amount of the solder. A reasonable amount of solder can avoid various defects caused by too much or too little solder. Too much solder may cause overflow, affect the appearance of the weldment, and may also cause stress concentration during the cooling process; too little solder cannot fill the weld, resulting in insufficient strength. By accurately controlling the amount of solder according to the size of the weld, these defects can be effectively reduced and the welding quality can be improved.

[0046] Reference Figures 1-10This embodiment also proposes a flame welding method for wind power components, which is applicable to a flame welding device for wind power components. The steps are as follows:

[0047] S1: The worker places the weldment 204 to be welded on the surface of the placement table 203, and then activates the electric telescopic rod 211 to make the weldment 204 contact the thickness measuring plate 220, causing the rotating disk 206 to rotate;

[0048] S2: The rotation of the rotating disk 206 causes the mounting block 208 to move inside the first sliding groove 207, thereby clamping and fixing the weldment 204. The distance between the two weldments 204 is adjusted according to the thickness of the weldment 204;

[0049] S3: Start the motor 330, which drives the crankshaft 322 to rotate, thereby driving the L-shaped plate 323 to rotate, thereby driving the connecting rod 324 to reciprocate. The reciprocating motion of the connecting rod 324 drives the second threaded cylinder 327 to reciprocate, thereby rotating the gear rod 310, and further causing the welding head 308 to reciprocate.

[0050] S4: When the thickness of the two welded parts 204 changes from the previous thickness, the weld between the two welded parts 204 changes. As the weld changes, the first rotating rod 319 rotates, thereby changing the amplitude of the up and down reciprocating motion of the second threaded rod 325, thereby changing the rotation amplitude of the rack rod 310, and thus the weld can be completely filled with solder.

[0051] S5: When the first tooth plate 312 moves, it drives the fourth gear 401 to rotate, and then the third threaded rod 406 reciprocates up and down inside the third threaded cylinder 404, thereby driving the baffle plate 407 to slide inside the control box 408, so as to control the feeding amount of the solder to match the width of the weld between the welds 204.

[0052] Specifically, the working process or working principle of the flame welding device for wind power components is as follows: after the worker places the weldment 204 to be welded on the placement table 203, the electric telescopic rod 211 is started, and the electric telescopic rod 211 can push the weldment 204 to move on the placement table 203. When the weldment 204 moves to the position of the thickness measuring plate 220, the thickness measuring plate 220 moves according to the thickness of the weldment 204, thereby causing the sliding block 215 to slide inside the third sliding groove 214, and the sliding of the sliding block 215 can compress the second spring 221. At the same time, the movement of the sliding block 215 can drive the first threaded rod 218 to move in the first threaded cylinder 2 17 moves inside, thereby driving the first threaded cylinder 217 to rotate, the rotation of the first threaded cylinder 217 can drive the second pulley 219 to rotate, and further can drive the first pulley 205 to rotate, and the rotation of the first pulley 205 can drive the rotating disk 206 to rotate, and the rotation of the rotating disk 206 can make the mounting block 208 move inside the first sliding groove 207, thereby clamping and fixing the welding part 204, and the gap between the two welding parts 204 can be adjusted according to the thickness of the welding parts 204, so that the gap between the two thicker welding parts 204 is smaller than the gap between the two thinner welding parts 204.

[0053] By setting the gear rod 310, when the gear rod 310 rotates, the rotating gear rod 310 can drive the welding head 308 to rotate together, and when the mounting member 307 slides on the surface of the second electric track 306, the welding head 308 can also slide on the surface of the gear rod 310, so that the welding head 308 can swing and rotate while moving horizontally, so as to achieve filling and welding of the weld. When the moving welding member 204 squeezes the first gear plate 312, the first gear plate 312 can be moved, and the first gear plate 312 can be moved. The movement of the toothed plate 312 can drive the first gear 311 to rotate. When the first gear 311 rotates, the rotating shaft 316 can be driven to rotate. The rotating rotating shaft 316 can drive the second gear 317 to rotate, thereby moving the third toothed plate 315. The movement of the third toothed plate 315 can drive the second toothed plate 314 to move. When the second toothed plate 314 moves, the third gear 318 can be driven to rotate. When the third gear 318 rotates, the first rotating rod 319 can be driven to rotate. 320 is connected to the eccentric part of the first rotating rod 319. Therefore, when the first rotating rod 319 rotates, the circular plate 320 can be driven to rotate eccentrically. When the circular plate 320 rotates, the rotating plate 321 can be driven to rotate. When the motor 330 is started, the crankshaft 322 can be driven to rotate, and the L-shaped plate 323 can be driven to rotate, and the connecting rod 324 can be driven to reciprocate up and down. The reciprocating motion of the connecting rod 324 can drive the second threaded rod 325 to move up and down, so that the second threaded cylinder 327 can be driven to rotate. The first bevel gear 328 is rotated back and forth, and the second threaded cylinder 327 is rotated back and forth, and the first bevel gear 328 is rotated back and forth, and the second bevel gear 329 is rotated back and forth, and the gear rod 310 is rotated back and forth. When the distance between the two welded parts 204 changes, the first rotating rod 319 is rotated, and the rotating plate 321 is rotated, so that the amplitude of the reciprocating movement of the second threaded rod 325 is changed, and the rotation amplitude of the gear rod 310 is changed.

[0054] When the first tooth plate 312 moves, it can drive the fourth gear 401 to rotate. When the fourth gear 401 rotates, the rotating fourth gear 401 can drive the third bevel gear 402 to rotate. The rotating third bevel gear 402 can drive the fourth bevel gear 405 to rotate. The rotation of the fourth bevel gear 405 can drive the third threaded cylinder 404 to rotate, and then the third threaded rod 406 can be made to reciprocate up and down inside the third threaded cylinder 404, thereby driving the baffle plate 407 to slide inside the control box 408, thereby controlling the amount of solder delivered.
