Description

Automated welding frame for wind turbine blade transport tooling cover Technical Field

[0001] This utility model relates to the field of welding frame technology, specifically an automated welding frame for the cover of a wind turbine blade transport fixture. Background Technology

[0002] With the growth of global energy demand and the rapid development of renewable energy, wind power, as a green, environmentally friendly, and sustainable energy source, is gradually becoming one of the main sources of global energy production. As a key component of wind turbines, the manufacturing and transportation of wind turbine blades directly impacts the safety, efficiency, and cost of the entire transportation process. During welding operations on the transport fixtures for wind turbine blades, welding frames are needed to secure the top cover and adjust its posture to improve welding efficiency.

[0003] Chinese utility model patent CN219684413U discloses an automated welding fixture, including a frame with a flip frame rotatably mounted on it. The flip frame has an mounting assembly for mounting parts. The fixture fixes the parts, and during welding, the mounting assembly secures the flip frame. After one side of the part is welded, the mounting assembly releases the flip frame, flips it, and then re-secures it using the mounting assembly before welding the other side of the part. This helps reduce the workload of workers clamping parts during welding, minimizes downtime, and improves welding quality. However, the levers in the fixture are fixed in slots on both sides, limiting the flip frame to a 180-degree rotation with the workpiece. This prevents adjustment to other desired welding angles, resulting in poor welding quality.

[0004] Therefore, this utility model provides an automated welding frame for the cover of a wind turbine blade transport fixture to solve the above problems. Summary of the Invention

[0005] This utility model provides an automated welding frame for the upper cover of a wind turbine blade transport fixture, aiming to solve the problems mentioned in the background art, such as the fact that the levers in the existing automated welding fixing frame are fixed in the fixing slots on both sides, which causes the flipping frame to only rotate 180 degrees with the workpiece, and cannot adjust the workpiece to other required welding angles, resulting in poor welding effect of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated welding frame for the upper cover of a wind turbine blade transport fixture, including a support plate, a lifting structure mounted on the support plate, and a rotating structure mounted on the lifting structure;

[0007] The rotating structure includes two sets of bearing seats and a rotating shaft rotatably mounted on the bearing seats. A fixed plate is installed at the end of the rotating shaft away from the bearing seats. Mounting plates and a first clamping plate are installed on the sidewalls of the fixed plate, located on the upper and lower sides. A threaded rod is installed on the mounting plate through a threaded hole. A second clamping plate is rotatably mounted on the lower end of the threaded rod. A worm gear is provided at the other end of the left rotating shaft. The rotating structure also includes a worm. By setting up the rotating structure, the workpiece to be welded can be rotated and fixed from 0 to 360 degrees, meeting the different welding angle requirements of the workpiece. This avoids the problem in existing automated welding fixtures where the levers are fixed in the fixing slots on both sides, causing the flipping frame with the workpiece to only rotate 180 degrees and unable to adjust to other required welding angles.

[0008] Preferably, the lifting structure includes a first fixed shell symmetrically mounted on a support plate and a lead screw rotatably mounted on the first fixed shell via a bearing at its upper end. The lead screw is threaded with a threaded sleeve and a driven bevel gear disposed at its lower end. A lifting plate connected to the bottom of a bearing seat is mounted on the side wall of the threaded sleeve. The lifting structure also includes a servo motor mounted on the side wall of the support plate. A transmission rod is provided at the drive end of the servo motor. An active bevel gear is mounted on the outer wall of the transmission rod, corresponding to the driven bevel gear.

[0009] Preferably, the second clamping plate is connected to the fixed plate by a sliding connection, and the two ends of the worm gear are rotatably mounted with fixed sleeves that are connected to the left lifting plate. A knob is provided at the upper end of the threaded rod, and a throttle is installed at the front end of the worm gear.

[0010] Preferably, the other end of the left-side rotating shaft is equipped with an extension shaft connected to the worm gear, and the worm gear and the worm are connected by a meshing connection.

[0011] Preferably, a traveling wheel is installed at the bottom of the support plate and at the corner, and the traveling wheel is a lockable swivel wheel.

[0012] Preferably, the support plate has mounting slots for mounting the driven bevel gear and the driving bevel gear. The support plate is rotatably connected to the lower end of the lead screw via a bearing, and the support plate is rotatably connected to the other end of the transmission rod via a bearing.

[0013] Preferably, a second fixed shell is symmetrically installed on the end face of the support plate, a vertical rod connected to the end face of the support plate is installed on the inner cavity end face of the second fixed shell, and a sliding sleeve slidably connected to the vertical rod is installed on the front face of the lifting plate.

[0014] Beneficial effects: By setting up a rotating structure, using bearing seats, rotating shafts, first clamping plates, worm gears and worms in combination, the workpiece to be welded can be rotated and fixed from 0 to 360 degrees. This meets the different welding angle requirements of the workpiece and avoids the problem in existing automated welding fixtures where the levers are fixed in the fixing slots on both sides, causing the flipping frame to only rotate 180 degrees with the workpiece and unable to adjust the workpiece to other required welding angles. This improves the welding effect and welding efficiency of the workpiece. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: This example provides an automated welding frame for the upper cover of a wind turbine blade transport fixture, as shown in Figures 1-5. The automated welding frame includes a support plate 1, a lifting structure 2 installed on the support plate 1, and a rotating structure 4 installed on the lifting structure 2.

[0023] The rotating structure 4 includes two sets of bearing seats 41 and a rotating shaft 42 rotatably mounted on the bearing seats 41. A fixed plate 43 is installed at the end of the rotating shaft 42 away from the bearing seats 41. A mounting plate 45 and a first clamping plate 44 are installed on the side wall of the fixed plate 43 and on the upper and lower sides. A threaded rod 46 is installed on the mounting plate 45 through a threaded hole. A second clamping plate 47 is rotatably mounted on the lower end of the threaded rod 46. A worm gear 48 is provided at the other end of the left rotating shaft 42. The rotating structure 4 also includes a worm 49.

[0024] In use, the two ends of the workpiece to be welded are placed on the end faces of the first clamping plates 44 on the left and right sides. The knobs 461 on the left and right sides are rotated in sequence. The knobs 461 drive the threaded rod 46 to rotate. The threaded rod 46 moves downward on the mounting plate 45. The threaded rod 46 drives the second clamping plate 47 to contact the top of the workpiece and continue to apply a certain force. The second clamping plate 47 cooperates with the first clamping plate 44 to clamp the workpiece. The throttle 492 drives the worm gear 49 to rotate. The worm gear 49 drives the worm wheel 48 to rotate. The worm wheel 48 drives the left rotating shaft 42 to rotate through the extension shaft 421. The rotating shaft 42 drives the workpiece to rotate through the fixed plate 43, the first clamping plate 44 and the second clamping plate 47 in sequence. This realizes the 0-360 degree rotation and fixing function of the workpiece to be welded, which meets the different welding angle requirements of the workpiece. It avoids the problem that the lever in the fixing frame of the existing automated welding is fixed in the fixing slots on both sides, which causes the flip frame to only rotate 180 degrees with the workpiece and cannot adjust the workpiece to other required welding angles. This improves the welding effect and welding efficiency of the workpiece.

[0025] In this embodiment, the second clamping plate 47 is connected to the fixed plate 43 by a sliding connection. The two ends of the worm 49 are rotatably mounted with fixed sleeves 491 that are connected to the left lifting plate 24. The upper end of the threaded rod 46 is provided with a knob 461, and the front end of the worm 49 is mounted with a handle 492. The other end of the left rotating shaft 42 is mounted with an extension shaft 421 that is connected to the worm wheel 48. The worm wheel 48 and the worm 49 are connected by a meshing connection.

[0026] The worm 49 is rotatably mounted on the end face of the left lifting plate 24 by the setting of the fixed sleeve 491, and is meshed with the worm wheel 48. After the worm wheel 48 stops driving the worm 49, it has a self-locking function, which realizes the function of fixing the workpiece after it rotates a certain angle.

[0027] In this embodiment, a traveling wheel 3 is installed at the bottom of the support plate 1 and at the corner. The traveling wheel 3 is a lockable universal wheel.

[0028] The presence of the three wheels facilitates the movement and transport of the automated welding frame for the transport tool cover, and the welding frame can be locked and parked in a certain area.

[0029] In Example 2, unlike Example 1, the existing automated welding fixture does not have a height adjustment function and cannot adjust the height of the welding fixture according to the actual welding requirements. Therefore, the lifting structure 2 includes a first fixed shell 21 symmetrically installed on the support plate 1 and a lead screw 22 rotatably installed on the first fixed shell 21 via a bearing. The lead screw 22 is threaded with a threaded sleeve 23 and a driven bevel gear 25 at the lower end of the lead screw 22. The side wall of the threaded sleeve 23 is equipped with a lifting plate 24 connected to the bottom of the bearing seat 41. The lifting structure 2 also includes a servo motor 26 installed on the side wall of the support plate 1. The drive end of the servo motor 26 is provided with a transmission rod 27. The outer wall of the transmission rod 27 is equipped with a driving bevel gear 28 corresponding to the driven bevel gear 25.

[0030] In use, the servo motor 26 is started to rotate in both directions by the control switch. The servo motor 26 drives the transmission rod 27 to rotate. The transmission rod 27 drives two sets of active bevel gears 28 to rotate in both directions synchronously. The active bevel gears 28 drive the driven bevel gears 25 to rotate in both directions. The driven bevel gears 25 drive the threaded sleeve 23 to move up and down. The threaded sleeve 23 cooperates with the sliding sleeve 241 to slide up and down on the outer wall of the vertical rod 210, realizing the height adjustment function of the lifting plate 24. The lifting plate 24 moves up and down with the traveling wheels 3. The traveling wheels 3 carry the workpiece to be welded to realize the height adjustment function. This avoids the problem that the existing automatic welding frame does not have a height adjustment function and cannot adjust the height of the welding frame according to the actual welding needs. This allows the welding frame to meet the welding head of different heights to weld the workpiece by adjusting the height. At the same time, the height of the welding frame can be adjusted to facilitate the loading and unloading of workpieces by workers of different heights, making the welding frame more flexible in use.

[0031] In this embodiment, the support plate 1 is provided with mounting grooves 11 for mounting the driven bevel gear 25 and the driving bevel gear 28. The support plate 1 is rotatably connected to the lower end of the lead screw 22 through bearings, and the support plate 1 is rotatably connected to the other end of the transmission rod 27 through bearings. A second fixed shell 29 is symmetrically mounted on the end face of the support plate 1. A vertical rod 210 connected to the end face of the support plate 1 is mounted on the inner cavity end face of the second fixed shell 29. A sliding sleeve 241 slidably connected to the vertical rod 210 is mounted on the front side of the lifting plate 24.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
