Description

Technical Field

[0001] This invention relates to the field of wind turbine manufacturing technology, and in particular to a welding rotary platform for wind turbine manufacturing. Background Technology

[0002] A fan is a mechanical device that converts mechanical energy into gas pressure energy or kinetic energy, thereby enabling gas transport, compression, or discharge. Its core function is to perform work on the gas through rotating components, changing the gas's flow rate, pressure, and direction to meet the needs of different industrial or civil applications. Fans are driven by prime movers such as motors or internal combustion engines, which rotate the impeller. The impeller applies centrifugal force or lift to the gas, giving it kinetic and pressure energy. In the fan manufacturing industry, the welding process is crucial, as its quality directly affects the fan's performance and service life.

[0003] In traditional welding methods, adjusting the position between the welding machine and the workpiece is extremely difficult. When dealing with fan workpieces of different sizes and shapes, it is impossible to flexibly adjust the distance between the welding machine and the workpiece, as well as the height of the welding machine. This makes it difficult to weld different parts of the workpiece at different heights. During the welding process, it is sometimes necessary to rotate the workpiece according to welding requirements to weld different parts of the workpiece. However, traditional welding equipment lacks an effective self-locking mechanism when rotating the workpiece, resulting in insufficient stability after rotation. After rotation, the workpiece is prone to move randomly due to external factors or its own gravity, causing the welding position to deviate and seriously affecting the welding accuracy. Furthermore, the positioning method of traditional welding platforms is relatively simple, lacking effective side and top positioning devices. When placing the workpiece, it is difficult to accurately position the side, and the workpiece is prone to side movement during welding, leading to welding position deviations. At the same time, there is also a lack of effective means for positioning the top of the workpiece. The workpiece may move up and down due to vibration during welding, further affecting the welding quality.

[0004] Therefore, it is necessary to provide a welding rotary platform for wind turbine manufacturing to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a welding rotary platform for fan manufacturing that can precisely control the horizontal distance and welding height between the welding machine and the workpiece, and the vertical axis rotation is completed by bevel gear meshing, ultimately driving the placement table to rotate, so as to meet the rotary welding requirements of different weld angles.

[0006] The welding rotary platform for wind turbine manufacturing provided by this invention includes: A base, the top of which is slidably connected to a movable platform, a movable component is mounted on the movable platform, the movable component includes a fixed seat fixedly mounted on the top of the movable platform, a slide rod slidably connected inside the fixed seat, a connecting plate fixedly mounted on the slide rod, a toothed plate fixedly mounted on the connecting plate, a motor fixedly mounted on the movable platform, a connecting shaft fixedly connected to the output end of the motor, a gear fixedly mounted on the connecting shaft, and a groove provided on the fixed seat.

[0007] Preferably, a welding machine mounting assembly is installed on the slide rod. The welding machine mounting assembly includes a fixing plate fixedly connected to the slide rod, and a first hydraulic rod is fixedly installed on the fixing plate. The piston rod of the first hydraulic rod is fixedly connected to a mounting seat.

[0008] Preferably, a fixed platform is fixedly installed on the top of the base, and a rotating assembly is installed on the fixed platform. The rotating assembly includes a rotating shaft rotatably installed at the bottom of the fixed platform, a worm gear rotatably installed on the fixed platform, a worm wheel meshing with the outer side of the worm gear, and bevel gears fixedly installed on both the worm wheel and the rotating shaft.

[0009] Preferably, a placement platform is fixedly installed on the top of the rotating shaft.

[0010] Preferably, the placement platform is provided with a side positioning component, the side positioning component including a groove formed inside the placement platform, a screw threaded inside the groove, and a rubber head rotatably mounted on the screw.

[0011] Preferably, the placement platform is further provided with a top positioning component, the top positioning component including a vertical plate fixedly installed on the placement platform, a second hydraulic rod fixedly installed on the vertical plate, a connecting frame fixedly connected to the piston rod of the second hydraulic rod, a moving block installed on the connecting frame, a pressure plate fixedly installed on the moving block, a limit sleeve fixedly installed on the connecting frame, and a limit block fixedly installed on the vertical plate.

[0012] Preferably, a limiting rod is fixedly installed on the connecting frame, and a spring is sleeved on the outer side of the limiting rod, and the moving block is slidably installed on the outer side of the limiting rod.

[0013] Preferably, a slider is fixedly installed at the bottom of the base, and the moving platform is slidably installed on the outside of the slider.

[0014] Compared with related technologies, the welding rotary platform for wind turbine manufacturing provided by the present invention has the following advantages: 1. This invention enables the horizontal movement of the slide bar through a moving component, which, in conjunction with the vertical lifting of the welding machine mounting component, allows for precise control of the horizontal distance between the welding machine and the workpiece, as well as the welding height. This meets the layered welding requirements of complex structures such as fan housings and impellers. The slide bar is rigidly connected to the welding machine mounting component, ensuring the stability of the welding machine's posture during horizontal movement and preventing welding trajectory deviation caused by mechanical vibration, thereby improving weld consistency. 2. The three-point clamping structure of the annular array of this invention can be adapted to fan workpieces of different diameters. Rapid positioning is achieved through screw rotation. The rubber head buffer design avoids scratching the workpiece surface. The self-locking of the threaded drive ensures that the clamping force is stable and lasting, preventing the workpiece from shifting due to thermal expansion or external force during welding. The second hydraulic rod drives the pressure plate to press down. Combined with the double buffer of the limit rod and spring, it avoids deformation of thin-walled workpieces caused by rigid impact. The sliding cooperation between the limit sleeve and the limit block eliminates the swing error during the lifting and lowering of the pressure plate, ensuring that the downward pressure acts vertically on the workpiece surface. 3. In this invention, the worm gear drives the worm wheel to achieve meshing rotation, and the bevel gear meshes to complete the vertical axis rotation, ultimately driving the placement table to rotate, meeting the rotation welding requirements of different weld angles. The self-locking characteristics of the worm gear and worm wheel ensure that there is no backlash error when the placement table stops rotating, avoiding workpiece displacement due to inertia or external force. Combined with the side and top positioning components, a double locking is formed, significantly improving welding accuracy. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-8 A welding rotary platform for wind turbine manufacturing includes a base 1, a movable platform 2 slidably connected to the top of the base 1, a movable assembly 3 mounted on the movable platform 2, and a fixed seat 31 fixedly mounted on the top of the movable platform 2. A slide rod 32 is slidably connected inside the fixed seat 31, a connecting plate 33 is fixedly mounted on the slide rod 32, a toothed plate 34 is fixedly mounted on the connecting plate 33, a motor 35 is fixedly mounted on the movable platform 2, a connecting shaft 36 is fixedly connected to the output end of the motor 35, a gear 37 is fixedly mounted on the connecting shaft 36, and a groove 38 is provided on the fixed seat 31. There are four fixed seats 31 in total, arranged in pairs, with one slide rod 32 sliding between every two fixed seats 31. The connecting shaft 36 is rotatably mounted on the top of the moving platform 2 via bearings, and a gear 37 is fixedly mounted in its middle. Two connecting plates 33 are fixedly connected between the two slide rods 32, and a toothed plate 34 is fixedly mounted between the two connecting plates 33. The connecting shaft 36 is driven to rotate by the motor 35, and the connecting shaft 36 drives the gear 37 on its outer side to rotate. The gear 37 meshes with the toothed plate 34, driving the toothed plate 34 and the slide rods 32 to move synchronously. The fixed seat 31 allows the slide rods 32 to move smoothly on the moving platform 2. The two sets of fixed seats 31 have grooves 38 on opposite sides, which allow the connecting plates 33 to pass freely without obstruction, thus allowing the slide rods 32 to move freely on the moving platform 2.

[0019] The slide rod 32 is equipped with a welding machine mounting assembly 4. The welding machine mounting assembly 4 includes a fixing plate 41 fixedly connected to the slide rod 32. A first hydraulic rod 42 is fixedly mounted on the fixing plate 41. The piston rod of the first hydraulic rod 42 is fixedly connected to a mounting seat 43. The fixing plate 41 is fixedly mounted at the end of the slide rod 32. A reinforcing rod to improve the stability of the fixing plate 41 is fixedly mounted between the fixing plate 41 and the connecting plate 33. A first hydraulic rod 42 with a downward piston rod is fixedly mounted on the top of the fixing plate 41. The piston rod of the first hydraulic rod 42 is fixedly connected to a mounting seat 43. The welding machine can be mounted through the mounting seat 43. During operation, the height of the mounting seat 43 and the welding machine can be adjusted by raising and lowering the first hydraulic rod 42, thereby welding parts of the workpiece at different heights. The welding mounting assembly 4 can move synchronously with the slide rod 32, thereby adjusting the distance between the welding machine and the workpiece.

[0020] The base 1 has a fixed platform 5 fixedly mounted on its top. A rotating assembly 6 is mounted on the fixed platform 5. The rotating assembly 6 includes a rotating shaft 61 rotatably mounted on the bottom of the fixed platform 5, a worm gear 62 rotatably mounted on the fixed platform 5, a worm wheel 63 meshing with the outer side of the worm gear 62, and bevel gears 64 fixedly mounted on both the worm wheel 63 and the rotating shaft 61. The fixed platform 5 is fixedly mounted on the top of the base 1 on the side opposite to the movable platform 2. The worm gear 62 is rotatably mounted on the side of the fixed platform 5 via bearings. A rod is fixedly mounted inside the worm wheel 63, and the rod is rotatably mounted on the top of the fixed platform 5 with its other end fixed. A bevel gear 64 is installed, and another bevel gear 64 is fixedly installed on the outside of the rotating shaft 61. The two bevel gears 64 mesh with each other. A shaft is also fixedly installed on the worm 62. A transmission device can be connected through the shaft. The transmission device drives the worm 62 to rotate. The worm 62 can drive the worm wheel 63 to rotate synchronously. The worm wheel 63 drives the bevel gear 64 on its outside to rotate. The two bevel gears 64 mesh with each other and rotate, driving the rotating shaft 61 to rotate. The self-locking performance of the worm wheel 63 and the worm 62 ensures the stability of the placement table 7 after rotation and avoids the workpiece from moving randomly and affecting the welding accuracy.

[0021] The top of the rotating shaft 61 is fixedly equipped with a placement platform 7, which is used to place the fan workpiece to be welded. The rotating shaft 61 drives the placement platform 7 to rotate synchronously, which can adjust the position between the workpiece and the welding, thereby improving the welding efficiency.

[0022] The placement table 7 is equipped with a side positioning component 8, which includes a groove 81 inside the placement table 7. A screw 82 is threaded inside the groove 81, and a rubber head 83 is rotatably mounted on the screw 82. Three elongated grooves 81 are arranged in a ring on the top of the placement table 7. A screw 82 is threaded inside the groove 81. A rubber head 83 is rotatably mounted on one end of the screw 82, and a handle is fixedly mounted on the other end. After the workpiece is placed on the placement table 7, the screw 82 is rotated by the handle. The screw 82 drives the rubber head 83 to move towards the center of the placement table 7 until it contacts the side of the workpiece, clamping and fixing the workpiece on the placement table 7. The side positioning component 8 can accurately position the side of the workpiece to prevent it from moving during welding, ensuring welding quality. The rubber head 83 can avoid damaging the workpiece.

[0023] The placement platform 7 is also equipped with a top positioning component 9. The top positioning component 9 includes a vertical plate 91 fixedly installed on the placement platform 7, a second hydraulic rod 92 fixedly installed on the vertical plate 91, a connecting frame 93 fixedly connected to the piston rod of the second hydraulic rod 92, a moving block 94 installed on the connecting frame 93, a pressure plate 95 fixedly installed on the moving block 94, a limit sleeve 97 fixedly installed on the connecting frame 93, and a limit block 98 fixedly installed on the vertical plate 91. The vertical plate is C-shaped and welded to one side of the placement platform 7. The piston rod of the second hydraulic rod 92... A connecting frame 93 is fixedly installed downwards on the rod, and a pressure plate 95 is fixedly installed on the connecting frame 93. When the second hydraulic rod 92 extends or retracts, it drives the connecting frame 93 and the moving block 94 to move downwards synchronously. When the moving block 94 moves downwards, it drives the pressure plate 95 to press down, which presses down and limits the top of the workpiece. This can effectively position the top of the workpiece and prevent the workpiece from moving up and down during the welding process, thereby further improving the welding quality. When the connecting frame 93 moves downwards, it drives the limiting sleeve 97 to slide outside the limiting block 98, which limits the connecting frame 93 and improves the stability of the connecting frame 93 during lifting and lowering.

[0024] The connecting frame 93 is fixedly installed with a limiting rod 96, and a spring is sleeved on the outside of the limiting rod 96. The moving block 94 is slidably installed on the outside of the limiting rod 96. There are two symmetrically arranged limiting rods 96. The moving block 94 slides on the outside of the limiting rod 96. When the pressure plate 95 moves down and contacts the workpiece, it drives the moving block 94 to slide on the outside of the limiting rod 96, compressing the spring. This buffers the pressure plate 95 and the workpiece, preventing the pressure plate 95 from generating excessive impact force on the workpiece and damaging it. At the same time, it ensures that the pressure plate 95 has appropriate pressure on the workpiece for positioning.

[0025] The base 1 has a slider 10 fixedly installed at its bottom, and the movable platform 2 is slidably installed on the outside of the slider 10. The bottom of the movable platform 2 has a groove that matches the slider 10. The movable platform 2 can move as a whole on the base 1 through the groove and the slider 10 to roughly adjust the welding position. Both sides of the movable platform 2 are threaded with limit bolts. After the movable platform 2 moves to the appropriate position, it can be fixed on the base 1.

[0026] The working principle of the welding rotary platform for wind turbine manufacturing provided by this invention is as follows: When motor 35 starts, it drives connecting shaft 36 to rotate on top of moving platform 2 via bearings. Connecting shaft 36 drives gear 37 on its outer side to rotate. Since gear 37 meshes with toothed plate 34, and toothed plate 34 is fixedly connected between two slide rods 32 via two connecting plates 33, the rotation of gear 37 will drive toothed plate 34 to move. The movement of toothed plate 34 will cause slide rod 32 to slide within fixed seat 31. There are four fixed seats 31, arranged in pairs, with each pair allowing one slide rod 32 to slide. Grooves 38 on opposite sides of the two sets of fixed seats 31 allow connecting plates 33 to move freely. By ensuring that the slide bar 32 can move smoothly and freely on the moving platform 2, the position of the slide bar 32 can be adjusted. The fixing plate 41 is fixedly installed at the end of the slide bar 32 and is connected to the connecting plate 33 by a reinforcing rod to improve stability. The first hydraulic rod 42, which is fixedly installed at the top of the fixing plate 41, moves downward. Its piston rod extends and retracts, driving the mounting base 43 to rise and fall. The mounting base 43 is used to install the welding machine. The height of the mounting base 43 and the welding machine can be adjusted by raising and lowering the first hydraulic rod 42. At the same time, the welding machine mounting assembly 4 moves synchronously with the slide bar 32, thereby adjusting the height of the welding machine. The distance between the welding machine and the workpiece meets the welding requirements for different heights and distances of the workpiece. The fixed platform 5 is fixedly installed on the top of the base 1 on the side opposite to the moving platform 2. The worm gear 62 is rotatably installed on the side of the fixed platform 5 through a bearing. The transmission device is connected to the shaft to drive the worm gear 62 to rotate. The worm gear 62 drives the worm wheel 63, which meshes with it, to rotate synchronously. The rod inside the worm wheel 63 is rotatably installed on the top of the fixed platform 5. The bevel gear 64 fixed at the other end of the rod rotates with the worm wheel 63. Another bevel gear 64 fixed on the outside of the rotating shaft 61 and the bevel gear 63 rotate together. 4. The meshing of the worm gears 63 and 62 drives the rotating shaft 61 to rotate. The self-locking properties of the worm gear 63 and worm 62 ensure the stability of the top platform 7 after rotation, preventing workpiece movement from affecting welding accuracy. The rotating shaft 61 drives the platform 7 to rotate synchronously, allowing adjustment of the position between the fan workpiece to be welded and the welding machine, improving welding efficiency. Three elongated grooves 81 are arranged in a ring on the top of the platform 7. A screw 82 is threaded into the groove 81. A rubber head 83 is rotatably mounted on one end of the screw 82, and a handle is fixedly mounted on the other end. After placing the workpiece on the platform 7, the screw 82 is rotated by the handle, causing the screw 82 to move towards the center of the platform 7 until it contacts the side of the workpiece, clamping and fixing the workpiece on the platform 7. This achieves precise side positioning of the workpiece, preventing side movement during welding. The rubber head 83 avoids damage to the workpiece. The bottom of the C-shaped upright plate 91 is welded to one side of the platform 7. A second hydraulic rod 92 is fixedly mounted on the upright plate 91 with its piston rod pointing downwards, and a connecting frame 93 is fixedly connected to it. When the second hydraulic rod 92 extends or retracts, it drives the connecting frame 93 and the moving block 94 to move down synchronously. The moving block 94 drives the pressure plate 95 to press down, which presses down and limits the top of the workpiece, thereby effectively positioning the top of the workpiece and preventing it from moving up and down during the welding process.The limiting sleeve 97 on the connecting frame 93 slides outside the limiting block 98 on the upright plate 91, limiting the connecting frame 93 and improving its lifting stability. Two limiting rods 96 are symmetrically fixed on the connecting frame 93, and the moving block 94 is slidably installed outside the limiting rods 96 with a spring sleeved on the outside. When the pressure plate 95 moves down and contacts the workpiece, it drives the moving block 94 to slide outside the limiting rods 96 and compress the spring, which plays a buffering role, preventing the pressure plate 95 from generating excessive impact force on the workpiece and damaging it, while ensuring that the pressure plate 95 has appropriate pressure on the workpiece for positioning.
