Description

Technical Field

[0001] The invention relates to the technical field of wind blade processing, and in particular to a burr processing device for wind power generation blades. Background Art

[0002] Wind blades are important components in wind power generation devices. The existing technology mainly produces the two halves of the blade separately through two molds, and then performs a mold closing operation. After the mold closing operation is completed, burrs will appear after the mold is closed, so the burrs need to be trimmed.

[0003] The Chinese patent announcement number CN117444298B discloses a wind turbine blade trimming processing device, including a bracket, two rotating blades are arranged on the bracket, the two rotating blades are located on the same vertical plane, the two rotating blades are separated at the upper and lower sides of the blade burr, and in the extension direction of the blade, one of the rotating blades is located at the front side of the other rotating blade, an abutment component, the abutment component is used to abut the blade body, and a walking component is used to drive the bracket to move along the extension direction of the blade. The bracket is provided with a first tool holder and a second tool holder, and the two rotating blades are respectively arranged on the first tool holder and the second tool holder. On the two tool holders, the abutment components are respectively arranged on the first tool holder and the second tool holder. The burrs of the blades are removed by mechanical equipment. Compared with manual work, the burr removal efficiency is higher. When the burrs of the blades are removed by two rotating blades arranged up and down and one in front and one behind, compared with a single rotating blade, the depth of the two rotating blades into the burrs is reduced, which can effectively reduce the ineffective contact area between the rotating blades and the blade burrs, thereby avoiding more dust flying. At the same time, compared with a single rotating blade, the two blades are less worn when removing the burrs of the blades, which increases the life of the rotating blades and saves certain costs.

[0004] The above-mentioned wind turbine blade trimming processing device processes the burrs of the blades by setting two rotating blades to remove the burrs at the upper and lower ends of the blades. However, since the blades are generally set in a fan-shaped shape, the position of the blades needs to be frequently moved when processing the burrs, which is relatively troublesome. The position of the burrs of the blades is not limited to the upper and lower ends, and burrs may also appear on the side edges, arc-shaped parts, etc. However, the above-mentioned device can only process the burrs at the upper and lower ends of the blades.

[0036] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 9 As shown, this embodiment provides a wind power blade burr processing device, including a main frame 100, a support base 110 is fixedly connected to the bottom of the main frame 100, a support plate 101 is fixedly connected to the bottom of the inner cavity of the main frame 100, a plurality of connecting columns 102 are fixedly connected to the top of the support plate 101, a driving fixing device 200 is arranged on the top of the main frame 100, a fan-shaped frame 120 similar in shape to a wind blade is fixedly connected to the inner wall of the main frame 100, a placement plate 103 for placing a wind blade is fixedly connected to the top of the connecting column 102, and the placement plate 103 is located in the inner cavity of the fan-shaped frame 120;

[0039] The driving and fixing device 200 is used to fix the fan blades on the top of the placement plate 103, and the inner wall of the fan-shaped frame 120 is provided with a moving component 300, which moves around the blades;

[0040] The surface of the moving component 300 is provided with a burr processing component 400 , and the burr processing component 400 can be attached to the side surface, the upper surface or the lower surface of the blade.

[0041] The blade is manually moved and placed on the surface of the placement plate 103, and then driven to drive the fixing device 200 to fix the blade on the surface of the placement plate 103. Then, the moving component 300 can slide on the inner wall of the fan-shaped frame 120, and the shape of the fan-shaped frame 120 is fan-shaped. At this time, the moving component 300 will slide around the shape of the fan-shaped frame 120, and the shape of the blade is similar to the shape of the fan-shaped frame 120. Since the burr processing component 400 is set on the surface of the moving component 300, the sliding of the moving component 300 can drive the burr processing component 400 to move around the blade, and the burr processing component 400 contacts the blade during the movement to remove the burrs at the contact position of the blade.

[0042] like Figure 1-Figure 9 As shown, the present invention takes into account that the shape of the blade is fan-shaped. When processing the burrs on the surface of the blade, it is necessary to move the blade to make it close to the burr processing component 400. After the burr processing of the contact portion between the blade and the burr processing component 400 is completed, the position of the blade is readjusted so that the portion that has not yet been cleaned of the burrs can contact the burr processing component 400, thereby processing the position of the blade that has not been in contact with the burr processing component 400. Since the blade position needs to be constantly moved and readjusted, the entire burr processing process becomes very cumbersome and time-consuming. Therefore, the blade is manually moved to place it on the top of the placement plate 103, and then driven to drive the fixing device 200 so that it can fix the blade on the top of the placement plate 103. Then, the moving component 300 is operated to drive the moving component 300 around the blade. The burr processing component 400 will remove the burrs on the surface of the blade, and there is no need to pause and adjust the blade after processing one portion as before.

[0043] And considering that when removing the burrs of the blade, the burrs are removed by setting two blades to fit the upper and lower ends of the blade, but the burr position of the blade is not limited to the upper and lower ends, and burrs may also appear on the side edges, arc-shaped parts, etc., and it may be necessary to use a handheld grinding device to re-process the position where the burrs have not been removed. Therefore, by setting a burr processing component 400 on the surface of the movable component 300, and the burr processing component 400 is in contact with the blade, the movement of the movable component 300 will drive the burr processing component 400 to slide on the blade surface. Since the burr processing component 400 can change the position of the burr processing component 400 in contact with the blade surface, the burr processing component 400 can adjust its position on the blade surface according to the burr situation on the blade surface.

[0044] In order to enable the driving and fixing device 200 to fix the blades on the surface of the placement plate 103, it is necessary to further disclose the parts of the driving and fixing device 200. Therefore, the driving and fixing device 200 includes a connecting frame 210 fixedly connected to the top of the main support 100, and a driving device 220 is fixedly connected to the top of the connecting frame 210. The end of the driving device 220 extends out of the connecting frame 210 and is fixedly connected to a telescopic fixing plate 230. The telescopic fixing plate 230 is located on the top of the placement plate 103. The operation of the driving device 220 can make the telescopic fixing plate 230 move downward to fix the blades on the surface of the placement plate 103.

[0045] In order to make the moving component 300 slide in the inner cavity of the fan-shaped frame 120, it is necessary to further disclose the parts of the moving component 300. Therefore, the moving component 300 includes a rack 310 sliding on the inner wall of the fan-shaped frame 120, and a limiting slide groove 121 is opened at the top of the inner cavity of the fan-shaped frame 120. The inner wall of the limiting slide groove 121 is slidably connected with a slide bar 311, and the bottom of the slide bar 311 is fixedly connected to the rack 310. When the rack 310 slides on the inner wall of the fan-shaped frame 120, the slide bar 311 slides on the inner wall of the limiting slide groove 121. At this time, the connection between the slide bar 311 and the limiting slide groove 121 can make the rack 310 slide on the inner wall of the fan-shaped frame 120.

[0046] In order to allow the rack 310 to slide on the inner wall of the fan-shaped frame 120, the inner wall of the rack 310 is meshed with a transmission gear 320, the transmission gear 320 rotates on the top of the main bracket 100, the outer edge of the transmission gear 320 is meshed with a connecting gear 330, and a first motor 340 is fixedly connected to the top of the main bracket 100. The first motor 340 is fixedly connected to the end of the connecting gear 330. The operation of the first motor 340 will electrically rotate the connecting gear 330, and the rotation of the connecting gear 330 will drive the transmission gear 320 to rotate. Since the transmission gear 320 is meshed with the rack 310, the rack 310 will slide on the inner wall of the fan-shaped frame 120.

[0047] In order to ensure that the rack 310 can remain stable and slide along the inner wall of the fan-shaped frame 120 when sliding in the inner cavity of the fan-shaped frame 120, a chain 312 is fixedly connected to the bottom of the rack 310, wherein a large gear 1020 is rotatably connected to the surface of one connecting column 102, and a small gear 1021 is rotatably connected to the surface of the other connecting column 102, and the large gear 1020 and the small gear 1021 are meshedly connected on the inner wall of the chain 312, and the chain 312 can be meshed with the small gear 1021 and the large gear 1020 through the sliding of the rack 310.

[0048] In order to allow the chain 312 to be in the inner cavity of the fan-shaped frame 120 and fixedly connected to the rack 310 when sliding, a connecting groove 122 is provided in the inner cavity of the fan-shaped frame 120, and the chain 312 is slidably connected to the inner wall of the connecting groove 122. By setting the connecting groove 122, the chain 312 can slide in the inner cavity of the fan-shaped frame 120 without affecting the fixed connection between the chain 312 and the rack 310, so that the rack 310 can slide on the inner wall of the fan-shaped frame 120.

[0049] In order to enable the burr processing component 400 to process the burr of the blade, the burr processing component 400 includes a mounting plate 410 fixedly connected to the surface of the rack 310, a rotator 411 fixedly connected to the surface of the mounting plate 410, an electric telescopic rod 412 is extended out of the inner wall of the rotator 411 by rotation, a sand tray 420 is fixedly connected to the surface of the electric telescopic rod 412, the surface of the sand tray 420 is in contact with the blade, the position of the sand tray 420 on the blade surface can be adjusted by rotating the electric telescopic rod 412 on the inner wall of the rotator 411, and the sand tray 420 can be brought into contact with the blade by the extension and retraction of the electric telescopic rod 412 itself.

[0050] In order to enable the electric telescopic rod 412 to rotate on the inner wall of the rotator 411, it is necessary to provide power to the electric telescopic rod 412. Therefore, a second motor 430 is fixedly connected to the surface of the mounting plate 410, and the end of the second motor 430 is fixedly connected to the electric telescopic rod 412. The operation of the second motor 430 can drive the electric telescopic rod 412 to rotate on the inner wall of the rotator 411.
