The small gap of the thick plate makes the amount of filler metal required for welding relatively small, thereby reducing the heat input during welding, and then effectively controlling the welding deformation, and 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 pores 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.

[0016] 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.

[0017] 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

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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.

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, the weldment 204 moves to the thickness measuring plate 220. When the welded part 204 is in the position, the thickness measuring plate 220 moves according to the thickness of the welded part 204, so that the sliding block 215 slides 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 inside the first threaded cylinder 217, and then drive the first threaded cylinder 217 to rotate.

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 the two 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 part 204, so that the gap between the two thicker welding parts 204 Smaller gaps between thick plates mean smaller welds, and smaller welds mean a relatively smaller amount of filler metal required for welding, which can reduce heat input during welding. When heat input is reduced, the thermal expansion and contraction of thick plates during welding will be relatively small, which can effectively control welding deformation and improve the dimensional accuracy and stability of the welded structure. Larger welds between thin plates can provide a more complete and continuous seal, reduce pores and defects in the welds, and thus reduce the possibility of corrosive media entering the welds, reduce corrosion channels, and improve the corrosion resistance of the welded structure. The weld interval range set by the entire device meets the requirements of the specification, and there will be no weld that is too large or too small.

According to the thickness of the welding piece 204, the distance between the two welding pieces 204 is adjusted; S3: Start the motor 330, the motor 330 drives the crankshaft 322 to rotate, and then drives the L-shaped plate 323 to rotate, thereby driving the connecting rod 324 to reciprocate, and the reciprocating motion of the connecting rod 324 drives the second threaded cylinder 327 to reciprocate, thereby rotating the gear rod 310, and then causing the welding head 308 to reciprocate; S4: When the thickness of the two welded parts 204 changes from the previous thickness, the weld between the two welded parts 204 changes, and when the weld changes, the first rotating rod 319 rotates, so that the amplitude of the up and down reciprocating motion of the second threaded rod 325 changes, so that the rotation amplitude of the gear rod 310 changes, and the weld can be completely filled with solder; S5: When the first tooth plate 312 moves, it drives the fourth gear 401 to rotate, and then the third threaded rod 406 makes a reciprocating motion 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 to meet the width of the weld between the welds 204.

[0027] 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 making the sliding block 215 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 can move 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 then drive the first pulley 205 to rotate, and the rotation of the first pulley 205 can drive the rotating disk 206 to rotate, 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.

[0028] 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, and when the moving welding member 204 squeezes the first tooth plate 312, the first tooth plate 312 can be moved, and the first 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 causing the third toothed plate 315 to move. 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. The first rotating rod 319 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 then the L-shaped plate 323 can be driven to rotate, and then 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. Reciprocating rotation occurs, 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, and then drive the gear rod 310 to rotate reciprocatingly. Through the setting of the first rotating rod 319, when the distance between the two welded parts 204 changes, the first rotating rod 319 rotates, and then the rotating plate 321 rotates, so that the amplitude of the reciprocating movement of the second threaded rod 325 changes, so that the rotation amplitude of the gear rod 310 changes.

[0029] 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 make a reciprocating motion up and down inside the third threaded cylinder 404, so as to drive the baffle plate 407 to slide inside the control box 408, so as to control the delivery amount of the solder.
