[0001] The present invention relates to the technical field of plasma arc welding, and more specifically, the present invention relates to a plasma arc welding machine for a hinge beam of a wind turbine. Background Art

[0002] The warning hinge beam of a wind turbine has three colors. Red indicates prohibition, yellow indicates warning, and green indicates permission. The warning hinge beam adopts a modular design. In order to keep the colors for a long time, the painted surface should be selected as a rough surface. The modules for displaying colors and the modules for assembly are usually fixed by welding. The existing warning hinge beam welding device only has a single welding function. It needs to be manually pressed and assembled and then sent to the welding position for welding, which is relatively labor-consuming and has too low work efficiency. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a plasma arc welding machine for a hinge beam of a wind turbine. The technical problem to be solved by the present invention is that the existing warning hinge beam welding device of a wind turbine only has a single welding function. It needs to be manually pressed and assembled and then sent to the welding position for welding, which is relatively labor-consuming and has too low work efficiency.

[0004] To achieve the above object, the present invention provides the following technical solution: A plasma arc welding machine for a hinge beam of a wind turbine, including a bottom plate. The upper end of the bottom plate is fixedly connected with a limiting ring. The inner wall of the limiting ring is rotatably connected with a central turntable. The upper end of the central turntable is fixedly connected with an extension ring. Six groups of second track grooves are evenly arranged on the central turntable. On both sides of each group of second track grooves, there are first track grooves. The upper end of the bottom plate is fixedly connected with a second fixing frame. The upper end of the second fixing frame is fixedly connected with a motor. The lower end of the second fixing frame extends to be provided with a main shaft. The lower end of the main shaft is fixedly connected with a three-way turntable. The lower end of the three-way turntable is rotatably connected with three groups of rotating rods. The lower end of each group of rotating rods is fixedly connected with a U-shaped slider. Two groups of plasma arc welding guns are arranged on each U-shaped slider. The upper end of each U-shaped slider is fixedly connected with a paint box, and the paints in the three paint boxes have different colors, namely yellow, green and red. Each U-shaped slider is provided with a second through hole. A sliding groove is arranged in each U-shaped slider. One side of the inner wall of each sliding groove is fixedly connected with a second spring. One end of each second spring is fixedly connected with a telescopic slider. A first through hole is arranged on each telescopic slider, and the first through hole corresponds to the position of the second through hole. The lower end of each U-shaped slider is fixedly connected with a sponge brush, and the sponge brush is located directly below the second through hole.

[0005] In a preferred embodiment, a third fixing frame is fixedly connected to the upper end of the bottom plate. One end of the third fixing frame is fixedly connected to a fixing sleeve. A first placement cavity is provided on the fixing sleeve, and multiple groups of first workpieces are placed in the first placement cavity. A second placement cavity is provided on the fixing sleeve, and there is a gap between the second placement cavity and the central turntable. Multiple groups of second workpieces are placed in the second placement cavity.

[0006] In a preferred embodiment, a first fixing frame is fixedly connected to the upper end of the bottom plate. An elastic plate is fixedly connected to the lower end of the first fixing frame, and multiple groups of first springs are fixedly connected between the elastic plate and the first fixing frame.

[0007] In a preferred embodiment, a material leakage hole is provided at the lower end of the bottom plate, and four groups of support legs are fixedly connected to the lower end of the bottom plate.

[0008] In a preferred embodiment, an inclined groove is provided on the first workpiece, and two groups of clamping protrusions are symmetrically arranged on the inner wall of the inclined groove. Clamping grooves are symmetrically arranged on both sides of the second workpiece.

[0009] The technical effects and advantages of the present invention:

[0010] The motor drives the three-way turntable to rotate through the main shaft. The three-way turntable drives the U-shaped slider to slide in the first track groove through the rotating rod. The three groups of U-shaped sliders will drive the central turntable to rotate during the sliding process. As the three-way turntable rotates, when the U-shaped slider moves above the combined first workpiece and second workpiece (the U-shaped slider moves from the center of the central turntable to the edge of the central turntable), the plasma arc welding gun starts to weld the gap between the first workpiece and the second workpiece. When the second track groove containing the first workpiece and the second workpiece rotates to the corresponding position of the second fixing frame, the U-shaped slider moves outwards to the limit. At this time, the telescopic slider is pressed by the extension ring, and the second spring is compressed. The telescopic slider is partially received into the U-shaped slider. At this time, the first through hole is aligned with the second through hole, and the pigment in the pigment box enters the sponge brush through the second through hole and the first through hole. When the U-shaped slider moves from the edge of the central turntable to the center of the central turntable, the sponge brush brushes the pigment on the second workpiece, and the pigment is quickly evaporated using the heat generated by welding to prevent secondary pollution. When the combination of the first workpiece and the second workpiece rotates above the material leakage hole, the combination of the first workpiece and the second workpiece falls through the material leakage hole. Repeating the above process can continuously complete the assembly, welding, and pigment brushing of the first workpiece and the second workpiece. Since the pigments in the three pigment boxes have different colors, three colors can be brushed. This device can simultaneously complete the automatic blanking and assembly of the first workpiece and the second workpiece, weld the weld seam, and finally apply pigments of different colors, and use the heat of welding to evaporate the pigments to avoid secondary pollution.

Detailed implementation manners

[0023] Consisting of Figure 1-10, the present invention provides a plasma arc welding machine for a hinge beam of a wind turbine, including a bottom plate 1. A limit ring 3 is fixedly connected to the upper end of the bottom plate 1. The inner wall of the limit ring 3 is rotatably connected to a central turntable 5. An extension ring 4 is fixedly connected to the upper end of the central turntable 5. Six groups of second track grooves 19 are evenly arranged on the central turntable 5. First track grooves 18 are arranged on both sides of each group of second track grooves 19. A second fixing frame 9 is fixedly connected to the upper end of the bottom plate 1. A motor 10 is fixedly connected to the upper end of the second fixing frame 9. The lower end of the second fixing frame 9 extends to be provided with a main shaft 23. A three-way turntable 24 is fixedly connected to the lower end of the main shaft 23. Three groups of rotating rods 20 are rotatably connected to the lower end of the three-way turntable 24. A U-shaped slider 25 is fixedly connected to the lower end of each group of rotating rods 20. Two plasma arc welding guns 22 are arranged on each group of U-shaped sliders 25. A paint box 26 is fixedly connected to the upper end of each group of U-shaped sliders 25, and the paint colors in the three paint boxes 26 are different, namely yellow, green, and red; yellow indicates warning, green indicates permission, and red indicates prohibition; a second through hole 29 is arranged on each group of U-shaped sliders 25. A sliding groove 31 is arranged in each group of U-shaped sliders 25. A second spring 30 is fixedly connected to one side of the inner wall of each sliding groove 31. One end of each second spring 30 is fixedly connected to a telescopic slider 27. A first through hole 28 is arranged on each telescopic slider 27, and the first through hole 28 corresponds to the position of the second through hole 29. A sponge brush 21 is fixedly connected to the lower end of each group of U-shaped sliders 25, and the sponge brush 21 is located directly below the second through hole 29; the motor 10 drives the three-way turntable 24 to rotate through the main shaft 23, and the three-way turntable 24 drives the U-shaped slider 25 to slide in the first track groove 18 through the rotating rod 20. The three groups of U-shaped sliders 25 will drive the central turntable 5 to rotate during the sliding process;As the three-way turntable 24 rotates, when the U-shaped slider 25 moves above the assembled first workpiece 16 and second workpiece 17 (the U-shaped slider 25 moves from the center of the central turntable 5 towards the edge of the central turntable 5), the plasma welding torch 22 starts to weld the gap between the first workpiece 16 and the second workpiece 17. When the second track groove 19 containing the first workpiece 16 and the second workpiece 17 rotates to the corresponding position of the second fixed frame 9, the U-shaped slider 25 moves outwards to the limit. At this time, the telescopic slider 27 is pressed by the extension ring 4, the second spring 30 is compressed, and a part of the telescopic slider 27 is retracted into the U-shaped slider 25. At this time, the first through hole 28 is aligned with the second through hole 29, and the pigment in the pigment box 26 enters the sponge brush 21 through the second through hole 29 and the first through hole 28. When the U-shaped slider 25 moves from the edge of the central turntable 5 towards the center of the central turntable 5, the sponge brush 21 brushes the pigment on the upper part of the second workpiece 17, and the heat generated by the welding quickly evaporates the pigment to prevent secondary pollution. When the combination of the first workpiece 16 and the second workpiece 17 rotates above the material leakage hole 15, the combination of the first workpiece 16 and the second workpiece 17 falls from the material leakage hole 15. Repeating the above process can continuously complete the assembly, welding, and pigment brushing of the first workpiece 16 and the second workpiece 17. Since the pigments in the three pigment boxes 26 have different colors, three colors can be brushed.

[0024] The upper end of the bottom plate 1 is fixedly connected with a third fixed frame 11. One end of the third fixed frame 11 is fixedly connected with a fixed sleeve 12. A first placement cavity 13 is arranged on the fixed sleeve 12, and multiple groups of first workpieces 16 are placed in the first placement cavity 13. A second placement cavity 14 is arranged on the fixed sleeve 12, and there is a gap between the second placement cavity 14 and the central turntable 5. Multiple groups of second workpieces 17 are placed in the second placement cavity 14; when the second track groove 19 rotates below the first placement cavity 13, a group of first workpieces 16 fall into the second track groove 19. When the second track groove 19 with the first workpiece 16 rotates directly below the second placement cavity 14, a group of second workpieces 17 fall into the inclined groove 32 on the first workpiece 16.

[0025] The upper end of the bottom plate 1 is fixedly connected with a first fixed frame 6. The lower end of the first fixed frame 6 is fixedly connected with an elastic plate 8. Multiple groups of first springs 7 are fixedly connected between the elastic plate 8 and the first fixed frame 6; when the second track groove 19 with the first workpiece 16 rotates directly below the first fixed frame 6, the elastic plate 8 presses down on the second workpiece 17, so that the clamping protrusion 33 is clamped into the clamping groove 34, and the second workpiece 17 is completely clamped into the inclined groove 32.

[0026] A leakage hole 15 is provided at the lower end of the bottom plate 1. Four groups of support legs 2 are fixedly connected to the lower end of the bottom plate 1. An inclined groove 32 is provided on the first workpiece 16. Two groups of clamping protrusions 33 are symmetrically arranged on the inner wall of the inclined groove 32. Clamping grooves 34 are symmetrically arranged on both sides of the second workpiece 17. The upper surface of the second workpiece 17 is rough to facilitate the attachment of the pigment. The clamping protrusion 33 can be inserted into the clamping groove 34 to facilitate the fixation of the first workpiece 16 and the second workpiece 17.

[0027] The device is used for welding the warning hinge beam of a wind turbine generator. The device is placed on a placement table ( Figure 10 ).

[0028] During specific operation, first, multiple groups of first workpieces 16 are placed in the first placement cavity 13, and multiple groups of second workpieces 17 are placed in the second placement cavity 14. The motor 10 is started. The motor 10 drives the three-way turntable 24 to rotate through the main shaft 23. The three-way turntable 24 drives the U-shaped slider 25 to slide in the first track groove 18 through the rotating rod 20. During the sliding process of the three groups of U-shaped sliders 25, the central turntable 5 is driven to rotate. When the second track groove 19 rotates to the lower part of the first placement cavity 13, one group of first workpieces 16 falls into the second track groove 19. When the second track groove 19 with the first workpiece 16 rotates to directly below the second placement cavity 14, one group of second workpieces 17 falls into the inclined groove 32 on the first workpiece 16. At this time, due to the obstruction of the clamping protrusion 33, the second workpiece 17 is not completely inserted into the inclined groove 32. When the second track groove 19 with the first workpiece 16 rotates to directly below the first fixing frame 6, the elastic plate 8 presses down on the second workpiece 17, causing the clamping protrusion 33 to be inserted into the clamping groove 34, and the second workpiece 17 is completely inserted into the inclined groove 32;

[0029] With the rotation of the three-way turntable 24, when the U-shaped slider 25 moves above the assembled first workpiece 16 and second workpiece 17 (the U-shaped slider 25 moves from the center of the central turntable 5 towards the edge of the central turntable 5), the plasma welding torch 22 is activated to weld the gap between the first workpiece 16 and the second workpiece 17. When the second track groove 19 containing the first workpiece 16 and the second workpiece 17 rotates to the corresponding position of the second fixed bracket 9, the U-shaped slider 25 moves outwards to the limit. At this time, the telescopic slider 27 is pressed by the extension ring 4, the second spring 30 is compressed, and part of the telescopic slider 27 is received into the U-shaped slider 25. At this time, the first through hole 28 is aligned with the second through hole 29, and the pigment in the pigment box 26 enters the sponge brush 21 through the second through hole 29 and the first through hole 28. When the U-shaped slider 25 moves from the edge of the central turntable 5 towards the center of the central turntable 5, the sponge brush 21 brushes the pigment on the upper part of the second workpiece 17, and the heat generated by welding is used to quickly evaporate the pigment to prevent secondary pollution. When the combination of the first workpiece 16 and the second workpiece 17 rotates above the material leakage hole 15, the combination of the first workpiece 16 and the second workpiece 17 falls from the material leakage hole 15. By repeating the above process, the assembly, welding, and pigment brushing of the first workpiece 16 and the second workpiece 17 can be continuously completed. Since the pigments in the three pigment boxes 26 have different colors, three colors can be brushed out.

[0030] Finally: The above description is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
