Description

Technical Field

[0001] This invention relates to the technical field of power generation equipment in emerging strategic industries, and in particular to an automatic assembly and welding equipment for marine energy power generation impellers. Background Technology

[0002] The exploitation of ocean energy generally involves using flowing seawater to drive a turbine, which in turn drives a generator to produce electricity, thus converting ocean energy into electrical energy. The utilization of ocean energy mainly includes tidal energy, ocean current energy, and wave energy.

[0003] In marine energy extraction equipment, the impeller is one of the main components, which converts marine energy into the kinetic energy of the impeller rotation. The impeller is mainly composed of a disk and blades. The disk is generally conical in shape, and the blades are generally arc-shaped. When assembling the impeller, multiple blades need to be welded one by one onto the disk, and the multiple blades are distributed in a ring. Since the projection of the contact position between the blade and the disk on the vertical plane is an oblique line, while its projection on the horizontal plane is an arc, the trajectory of the contact position is irregular. Existing welding equipment cannot handle this irregular welding trajectory, and welding can only be done manually. Due to the complexity of the welding trajectory, workers need to spend a lot of effort to weld, resulting in high energy and physical exertion, low work efficiency, and poor weld uniformity, which can easily affect the weld strength and quality.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0027] like Figures 1 to 2 As shown, an automatic assembly and welding device for marine power generation turbines according to the present invention includes a wheel 1 and multiple blades 2, which are arranged in a ring on the top of the wheel 1. It also includes an arc-shaped guide rail 3, which is located above the wheel 1 and whose center coincides with the axis of the wheel 1. A fan plate 4 is slidably mounted on the arc-shaped guide rail 3, and an arc-shaped guide groove 5 is provided on the fan plate 4. A vertical plate 6 is provided below the arc-shaped guide rail 3, and an oblique guide groove 7 is provided on the vertical plate 6. A first slider 8 is slidably mounted in the oblique guide groove 7. A sliding column 9 is fixed to the top of the first slider 8 and slides within the arc-shaped guide groove 5. The bottom of the first slider 8 is set to a horizontal plane, and a welding torch 10 is provided at the bottom of the first slider 8.

[0028] Specifically, the center of the arc-shaped guide rail 3 coincides with the vertical axis of the wheel 1, the arc radius and direction of the arc-shaped guide groove 5 correspond to the arc radius and direction of a blade 2 on the wheel 1, and the tilt angle of the inclined guide groove 7 is the same as the tilt angle of the cross section of the wheel 1.

[0029] In use, the arc-shaped guide rail 3 and the vertical plate 6 are pushed down, thereby moving the welding torch 10 down to the docking position of the wheel 1 and the blade 2, fixing the fan plate 4. The arc-shaped guide rail 3 is then pushed to slide on the fan plate 4, and the arc-shaped guide rail 3 moves synchronously with the vertical plate 6. The vertical plate 6 drives the welding torch 10 to move synchronously via the first slider 8. Since the arc-shaped guide groove 5 is arc-shaped, when the vertical plate 6 moves, it can push the sliding column 9 to slide within the arc-shaped guide groove 5 via the first slider 8, thus making the movement trajectory of the sliding column 9 arc-shaped. The sliding column 9 drives the first slider 8 to move in an arc shape, and... As the sliding column 9 moves within the arc-shaped guide groove 5, it gradually approaches the position of the arc-shaped guide rail 3. At this time, the sliding column 9 synchronously drives the first slider 8 to slide within the inclined guide groove 7. The first slider 8 slides downward synchronously, so that the first slider 8 moves in an arc shape while simultaneously tilting. The first slider 8 drives the welding torch 10 to perform a combination of arc-shaped and tilting movements. At this time, the welding torch 10 moves along the trajectory of the docking position of the wheel 1 and the blade 2. The welding torch 10 performs welding processing on the position of the wheel 1 and the blade 2, thereby realizing the automatic welding and assembly of the wheel 1 and the blade 2.

[0030] In use, the fan plate 4 can also move on the arc-shaped guide rail 3, and the fan plate 4 moves synchronously with the wheel 1. The arc-shaped guide groove 5 pushes the sliding column 9 to move outward in sync. The sliding column 9 drives the first slider 8 to move tilted in the inclined guide groove 7, thereby causing the welding torch 10 to move tilted. Since the fan plate 4 and the wheel 1 move synchronously, the welding torch 10 moves tilted and the wheel 1 rotates in a linked motion state. At this time, the welding torch 10 can move along the docking trajectory of the wheel 1 and the blade 2, thereby realizing the automatic welding work of the welding torch 10 at the docking position of the wheel 1 and the blade 2.

[0031] It can be seen that by combining the tilting movement of the welding torch 10 relative to the wheel 1 in the vertical plane and the arc movement in the horizontal plane, the welding torch 10 can move along the trajectory of the docking position of the wheel 1 and the blade 2, thereby enabling the welding torch 10 to perform precise welding, realize automated welding work, effectively simplify the welding method, reduce welding difficulty, save physical strength, energy and time, improve work efficiency, and effectively improve the stability of welding and the uniformity of weld, thereby improving welding quality and strength.

[0032] like Figures 3 to 5 As shown, as a preferred embodiment of the above, it also includes a chassis 11, a core column 15 is provided in the middle of the chassis 11, a wheel 1 is placed on the top of the core column 15, a plurality of second sliders 12 are slidably provided on the top of the chassis 11, the second sliders 12 slide along the radial direction of the chassis 11, a pressing plate 13 is fixed on the top of the second sliders 12, and a lower pressure plate 14 is rotatably provided on the top of the pressing plate 13.

[0033] Specifically, multiple second sliders 12 are pushed closer together, thereby causing multiple extrusion plates 13 to move closer together. The extrusion plates 13 contact the outer wall of the wheel 1 and extrude pressure on it. Multiple extrusion plates 13 extrude pressure on the wheel 1 simultaneously, thereby fixing the wheel 1 in the horizontal direction. The lower pressure plate 14 is flipped so that it rotates to the top of the wheel 1 and presses down on the wheel 1, thereby pressing and fixing the wheel 1 in the vertical direction with the lower pressure plate 14 and the core column 15. At this time, the wheel 1 is doubly fixed, which effectively improves the fixing strength of the wheel 1. Furthermore, since multiple extrusion plates 13 and multiple lower pressure plates 14 move synchronously, the wheel 1 can be positioned in both the horizontal and vertical directions.

[0034] like Figure 5 As shown, in a preferred embodiment, the two side walls of the extrusion plate 13 are each provided with a first gear 16, and a toothed rack 17 is meshed on the first gear 16. The bottom of the toothed rack 17 is fixed to the top of the chassis 11. A sliding sleeve 18 is provided on the side wall of the first gear 16. A connecting plate 19 is fixed on the lower pressure plate 14. A U-shaped plate 20 is provided at the outer end of the connecting plate 19. The two ends of the U-shaped plate 20 pass through the two sliding sleeves 18 and are slidably connected.

[0035] Specifically, the two first gears 16 are located on the front and rear sides of the extrusion plate 13, respectively. When the second slider 12 moves toward the wheel 1, the second slider 12 drives the first gear 16 to roll on the gear rack 17 through the extrusion plate 13. At this time, the first gear 16 drives the U-shaped plate 20 to tilt and rotate through the sliding sleeve 18. The U-shaped plate 20 pushes the lower pressure plate 14 to flip toward the top of the wheel 1 through the connecting plate 19, thereby realizing the linkage effect of the translation of the extrusion plate 13 and the flipping of the lower pressure plate 14, realizing the synchronous movement of the extrusion plate 13 and the lower pressure plate 14, thereby improving the synchronicity of fixing the wheel 1 in two directions, improving the positioning accuracy, and reducing the number of power sources and simplifying the structure.

[0036] like Figures 4 to 5 As shown, in a preferred embodiment of the above, the top of the chassis 11 is provided with a first motor 21 and a bevel ring 23. The bevel ring 23 is sleeved on the outside of the core column 15 and is rotatably mounted on the chassis 11. The output end of the first motor 21 is provided with a bevel gear 22, which meshes with the bevel ring 23. The top of the bevel ring 23 is provided with a plurality of push-pull sleeves 24.

[0037] The side wall of the extrusion plate 13 is provided with a first inclined arm 25, and the outer end of the first inclined arm 25 is provided with a second inclined arm 26. The outer end of the second inclined arm 26 is rotatably mounted on the core column 15, and the push-pull sleeve 24 is slidably sleeved on the second inclined arm 26.

[0038] Specifically, the first motor 21 can drive the bevel gear ring 23 to rotate through the bevel gear 22. The bevel gear ring 23 pushes the multiple second inclined arms 26 to rotate at an angle through multiple push-pull sleeves 24. The multiple second inclined arms 26 pull the multiple extrusion plates 13 to move synchronously through multiple first inclined arms 25, thereby driving the second slider 12, the extrusion plate 13 and the lower pressure plate 14 to move synchronously. At this time, the push-pull sleeves 24 can slide on the second inclined arms 26.

[0039] like Figure 1 As shown, as a preferred embodiment of the above, a rotating ring 27 and a toothed ring 28 are sleeved on the outer circumference of the chassis 11, and the rotating ring 27 is rotatably connected to the chassis 11. A support plate 29 is provided on the rotating ring 27, and the support plate 29 is connected to the arc-shaped guide rail 3 and the vertical plate 6.

[0040] A second motor 30 is provided on the support plate 29, and a second gear 31 is provided at the output end of the second motor 30. The second gear 31 is meshed with the gear ring 28.

[0041] Specifically, the second motor 30 can drive the rotating ring 27 to rotate on the chassis 11 through the second gear 31 and the gear ring 28, thereby driving the support plate 29, the arc-shaped guide rail 3 and the upright plate 6 to move in an arc.

[0042] like Figure 1 As shown, in a preferred embodiment, the support plate 29 is composed of a fixed sleeve plate 32 and a right-angle slide plate 33. The fixed sleeve plate 32 is fixed on the rotating ring 27, the second motor 30 is fixed on the fixed sleeve plate 32, the bottom of the right-angle slide plate 33 is slidably inserted into the fixed sleeve plate 32, the top of the right-angle slide plate 33 is connected to the side wall of the arc-shaped guide rail 3, the upright plate 6 is fixed on the right-angle slide plate 33, and a plurality of limiting plates 34 are provided on the outer side wall of the right-angle slide plate 33. A first cylinder 35 is provided on the limiting plate 34, and the fixed end of the first cylinder 35 is installed on the fixed sleeve plate 32.

[0043] Specifically, when the first cylinder 35 extends or retracts, the first cylinder 35 can push the right-angle slide plate 33 to move up and down through the limiting plate 34, thereby adjusting the total length of the support plate 29 and facilitating the adjustment of the position of the welding torch 10. When the right-angle slide plate 33 moves downward, the limiting plate 34 can contact the top of the right-angle slide plate 33. At this time, the limiting plate 34 can limit the position of the right-angle slide plate 33, thereby quickly positioning the position of the welding torch 10.

[0044] like Figure 2 As shown, in a preferred embodiment, the top of the right-angle slide plate 33 is rotatably provided with a telescopic rod 36 and a second cylinder 37. The movable end of the telescopic rod 36 is rotatably mounted on the fan plate 4, and the movable end of the second cylinder 37 is rotatably mounted on the side wall of the fixed end of the telescopic rod 36.

[0045] Specifically, when the second cylinder 37 extends or retracts, the second cylinder 37 can push the telescopic rod 36 to swing, and the telescopic rod 36 can drive the fan plate 4 to slide on the arc-shaped guide rail 3, thereby providing power to the fan plate 4. At the same time, when the rotating ring 27 rotates forward on the chassis 11, and the fan plate 4 moves in the opposite direction on the arc-shaped guide rail 3, the purpose of fixing the fan plate 4 can be achieved through the combination and cancellation of the two motion modes.

[0046] like Figure 2 As shown, in a preferred embodiment, the first slider 8 is fixed with a first adjusting plate 38 at its bottom, the first adjusting plate 38 is rotatably provided with a second adjusting plate 39 at its bottom, the welding gun 10 is fixed with the bottom of the second adjusting plate 39, the side wall of the second adjusting plate 39 is provided with a third adjusting plate 40, the bottom of the first slider 8 is rotatably provided with a third cylinder 41, and the movable end of the third cylinder 41 is rotatably mounted on the third adjusting plate 40.

[0047] Specifically, when the third cylinder 41 extends or retracts, the third cylinder 41 can push the second adjusting plate 39 to rotate on the first adjusting plate 38 through the third adjusting plate 40, thereby adjusting the tilt direction of the welding torch 10. This makes it easier for the torch head to tilt towards the docking position of the wheel 1 and the blade 2, thereby improving the uniformity of the heating part at the docking position of the wheel 1 and the blade 2, and thus improving the welding effect.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
