Description

Technical Field

[0001] This invention belongs to the field of plate welding technology, and specifically relates to a plate welding device for the wear-resistant part of a wind turbine blade. Background Technology

[0002] Currently, in industrial sectors such as mining and cement, centrifugal fans operate under harsh conditions of high dust levels for extended periods. Hard particles in the conveyed medium continuously impact the working surface of the impeller blades, causing abrasive wear on the metal materials. Existing technologies commonly employ manual welding to deposit a wear-resistant alloy layer onto the easily worn areas of the blades before blade forming. However, manual welding relies entirely on the skill level and experience of the operators. If the operators lack sufficient skill or experience, poor welding quality is likely to occur, resulting in insufficient penetration of the wear-resistant alloy layer. Consequently, under continuous impact from hard particles, the layer is prone to detachment and cracking, failing to provide effective protection. Summary of the Invention

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the rotating mechanism includes a support 15 and a sleeve 38. The support 15 is installed on the side of the base 14.

The thickness of gear 2 39 is greater than the thickness of gear 17.

[0027] In this invention, the cavity of the movable component 25 is provided with a plurality of grooves 3, and the outer periphery of the inner component 24 is provided with a plurality of protrusions 1, which are slidably connected to the grooves 3.

[0028] In this invention, the protrusion can slide up and down along the groove under the push of the cylinder 22.

[0029] In this invention, cylinder 3 22 is located in the middle of support member 1 5.

[0030] In this invention, the lower part of the sleeve 38 is open, the connecting post 37 is located inside the sleeve 38, and when the drive motor 16 is working, the sleeve 38 can rotate around the outer periphery of the connecting post 37.

[0031] In this invention, the distance between the side of bracket 6 and the side of guide rail 2 is less than the distance between bracket 8 and the side of guide rail 2.

[0032] In this invention, both loading and unloading devices are located on the side of the guide rail 2 near the support 8.

[0033] In this invention, the side of the base 14 near the guide rail 2 is a certain distance away from the guide rail 2, and this distance can be set according to the site conditions.

[0034] In this invention, the straight line formed by bracket 6 and bracket 8 is perpendicular to the guide rail 2.

[0035] In this invention, the walking mechanism 1 is an existing walking mechanism that can be controlled by a controller to move along the guide rail 2.

[0036] In this invention, the first adsorption element 13 is an existing vacuum adsorption mechanism, the second adsorption element is an existing electromagnetic adsorption mechanism, and the fourth connecting column 37 is made of iron.

[0037] In this invention, when drive motor 16 is not working and drive motor 40 is working, gear 2 39 can move up and down along gear 17.

[0038] In this invention, the automatic welding gun 9 is a conventional automatic welding gun.

[0039] In this invention, after the four clamping discs 33 clamp the plate, there is a certain distance between the height of the plate and the lower end of the automatic welding gun 9, which is within the welding range of the automatic welding gun 9.

[0040] In this invention, the two loading and unloading devices are respectively connected to the output end of the previous processing equipment and the input end of the next processing equipment, and can also be connected to the loading platform and the unloading platform.

[0041] In this invention, the horizontal plate 44 and the vertical plate 45 are perpendicular.

[0042] In this invention, the welding device is externally connected to a controller, and the walking mechanism 1, the pushing device, the clamping device, and the loading and unloading device are all communicatively connected to the controller.

[0043] In this invention, the walking mechanism 1, the automatic welding gun 9, the power supply, cylinder 1 3, cylinder 3 22, cylinder 4 28, the pushing cylinder 26, the drive motor 2 40, the cylinder 2 19, the adsorption component 1 13, the adsorption component 2, and the drive motor 1 16 are all connected to the controller for communication.

[0044] In this invention, if the plate to be welded is square or round, the cylinders 28 of the four clamping components can be synchronously controlled by the controller. If the plate to be welded is rectangular, the cylinders 28 of the corresponding clamping components can be synchronously controlled by the controller.

[0045] In this invention, cylinder 28 and the corresponding push cylinder 26 are controlled synchronously.

[0046] In this invention, after cylinder 3 22 is started, cylinder 3 22 drives the built-in component 24 to move inside the outer shell 1 23, which in turn drives the connecting component 3 27 to move closer to or further away from the outer shell 1 23, causing the clamping plate 33 to converge toward the center or open outward.

[0047] The working principle of this invention is as follows: When the output end of the previous processing equipment delivers the board material, cylinder 19 of the loading and unloading device located at the loading end is activated. Cylinder 19 pushes the adsorption component 13 to a suitable position, namely the middle position of the board material. Cylinder 19 is then closed, and drive motor 40 is activated. Drive motor 40 drives rotating plate 43 to rotate, which in turn drives fixing component 46 to move via horizontal plate 44 and vertical plate 45. This, in turn, drives sliding column 18 to slide downward along the sliding groove of base 14. Connecting column 35, connecting column 36, connecting column 34, and connecting column 37 descend synchronously, lowering adsorption component 13 to the upper surface of the board material. During this process, adsorption component 2 (electromagnetic adsorption mechanism) remains energized to ensure that sleeve 38 and connecting column 37 are relatively fixed. Drive motor 40 is then closed, and adsorption component 13 is activated, adsorbing the board material. Drive motor 40 is then activated again, causing sliding column 18 to move the board material upward to a suitable position, namely the middle position of the board material. The material rotation is not obstructed by the components below. The drive motor 40 is turned off, the adsorption component 2 is de-energized and releases its fixation to the connecting column 37. The drive motor 16 starts and drives the sleeve 38 to rotate along the outer circumference of the connecting column 37 through the meshing of gear 17 and gear 2 39. This, in turn, drives the cylinder 19 and the adsorbed material to rotate to the clamping device above the guide rail 2. The cylinder 3 adjusts the position of the material so that it is in the middle position of the clamping device. The thickness of gear 2 39 is greater than that of gear 17 to ensure that the meshing relationship does not disengage during the lifting process and to limit the lifting.

[0048] Activate the second adsorption component to fix the fourth connecting column 37. Activate the second drive motor 40 to move the sliding column 18 downwards to a suitable position. Then, turn off the second drive motor 40 and activate the third cylinder 22. The third cylinder 22 pushes the built-in component 24 to slide along the third groove, causing the four clamping components to tighten synchronously. Finally, the clamping plate 33 on the fourth connecting component 32 fits against the outer periphery of the plate, clamping the plate. Turn off the third cylinder 22 and the first adsorption component 13. Activate the second drive motor 40 to move the sliding column 18 upwards. Turn off the second drive motor 40 and activate the traveling mechanism 1. The traveling mechanism 1 moves the plate along the guide rail 2. During the movement of the traveling mechanism 1, the loading and unloading device at the loading end returns to its initial position. After the traveling mechanism 1 moves to a suitable position, turn off the traveling mechanism 1 and activate the automatic welding gun 9 to weld the wear-resistant part of the plate. During the welding process, the first cylinder 3 and the traveling mechanism 1 push the plate to move in coordination with the automatic welding gun 9, allowing the automatic welding gun 9 to perform wear-resistant welding on a certain range of the plate.

[0049] After the wear-resistant part is welded, the walking mechanism 1 is activated and continues to move along the guide rail 2. After moving to the position, the cylinder 19 of the loading and unloading device at the unloading end is activated. The cylinder 19 pushes the adsorption component 13 to move to the middle position above the welded plate. The cylinder 19 is closed, and the drive motor 40 is activated, so that the sliding column 18 slides down along the sliding groove of the base 14, so that the adsorption component 13 contacts the upper surface of the plate. During this process, the adsorption component 2 (electromagnetic adsorption mechanism) is kept energized to ensure that the sleeve 38 and the connecting column 37 are relatively fixed. The drive motor 40 is closed, and the adsorption component 13 is activated. The adsorption component 13 adsorbs the plate. The cylinder 22 is activated, and the cylinder 22 pushes the built-in component 24 to slide along the groove 3, driving the four clamping components to simultaneously detach from the plate. Finally, the clamping plate 33 on the connecting component 32 detaches from the outer periphery of the plate, and the cylinder 22 is closed.

[0050] Turn on drive motor 2 40, causing sliding column 18 to move the plate upward to a suitable position, i.e., the plate rotation is not obstructed by the components below. Turn off drive motor 2 40, de-energize adsorption component 2 and release it from fixing to connecting column 4 37. Drive motor 1 16 starts, and through the meshing transmission of gear 1 17 and gear 2 39, drives sleeve 1 38 to rotate along the outer circumference of connecting column 4 37, thereby driving cylinder 2 19 and the adsorbed plate to rotate to the input end or unloading table of the next processing equipment. Turn off drive motor 1 16, turn on adsorption component 2 and drive motor 2 40, causing sliding column 18 to move the plate downward to a suitable position, i.e., the plate falls above the input end or unloading table of the next processing equipment. Turn off drive motor 2 40 and adsorption component 2, completing the welding of the wear-resistant part of the plate.

[0051] In this invention, before welding multiple plates of the same size, it is necessary to adjust the four clamping components according to the size of the plates, activate the push cylinder 26 and cylinder 28, and adjust the distance between the relative clamping plates to meet the requirements of plate clamping.

[0052] In this invention, the above process can be automatically controlled by a controller.

[0053] In this invention, the above process can be adjusted according to the on-site conditions.
