[0058] For the cross-flow insert riveting machine, please refer to Figures 1-3 As shown, it has a frame 100. The frame 100 is in a cabinet structure. The frame 100 serves as the carrier of the entire device, and the specific structure of the frame 100 can be changed; in this embodiment, a large panel 110 is provided on the frame 100. The frame 100 is divided into a lower structure and an upper structure by the large panel 110. The lower structure is enclosed by a frame door, while the front and back of the upper structure are open structures, which is convenient for processing;

[0059] Figure 3 In order to facilitate the display of the specific structure of the cross-flow insert riveting machine, the frame 100 is hidden.

[0060] Installed inside the said frame 100 are: a riveting device 200, a machine head device 300, and a feeding device 400.

[0061] The present invention is used for assembling large wind wheels. Here, the large wind wheel refers to a wind wheel with a relatively large axial length. Therefore, the machine head device 300 is installed inside the frame 100, and it is distributed in the upper and lower layers of the frame 100. When assembling the cross-flow wind wheel, the wind wheel blades are inserted from top to bottom and inserted into the upper and lower layers of the frame 100 for assembly.

[0062] The said riveting device 200 is located above the machine head device 300 for riveting; the riveting device 200 can adjust the riveting position relative to the diameter of the cross-flow wind wheel to adapt to riveting cross-flow wind wheels of different diameters.

[0063] The feeding device 400 is installed on the large panel 110 and orderly inserts wind turbine blades into the mold assembly 310 of the machine head device 300.

[0064] Please refer to Figures 4-6 As shown, the machine head device 300 is distributed above and below the large panel 110 to adapt to the assembly of large-sized wind turbines. When inserting the blades, the wind turbine blades pass through the mold assembly 310 and extend to the moving lower demolding plate 351 at the bottom of the machine head device 300.

[0065] The machine head device 300 includes: an upper moving plate 301, a mold assembly 310, an upper opening and closing chuck assembly 320, a holding ring assembly 330, and a rotation driving assembly 340;

[0066] The mold assembly 310 is installed on the upper moving plate 301, and the upper opening and closing chuck assembly 320 is installed on the upper moving plate 301 and distributed around the mold assembly 310; multiple groups of holding ring assemblies are longitudinally distributed below the upper moving plate 301; the rotation driving assembly 340 is located at the bottom of the entire machine head device 300, and the rotation driving assembly 340 drives the mold assembly 310 to rotate.

[0067] Further, please refer to Figure 18 As shown, the mold assembly 310 includes: a mold sleeve 311, an insert mold 312, a mold core 313, and a positioning die pin 314;

[0068] The mold assembly 310 is installed in the upper moving plate 301 through a bearing, and this bearing is a mold cross bearing 315, so that the mold assembly 310 can rotate smoothly when driven by the rotation driving assembly 340.

[0069] The mold sleeve 311 is in a sleeve shape and is hollow, facilitating the wind turbine blades to pass through and continue to be inserted downward. The mold sleeve 311 is fixed to the inner ring of the mold cross bearing 315. The insert mold 312 is installed on the top of the mold sleeve 311. At the top of the insert mold 312, there are two groups of insert slots 3121 with different diameters, which can adaptively assemble two groups of cross-flow wind turbines with different diameters without frequently replacing the mold assembly 310.

[0070] Optionally, or there are three groups of insert slots with different diameters at the top of the insert mold 312.

[0071] The mold core 313 is installed at the center of the insert mold 312 and is fixed to the insert mold 312. The positioning die pin 314 is arranged around the mold core 313. The positioning die pin 314 is used for positioning when the fixing ring of the cross-flow wind turbine is installed, so that it can be correctly installed.

[0072] The described mold sleeve 311, insert mold 312, and mold core 313 are all made of high-hardness metal materials. A slot 3111 is provided on the mold sleeve 311 corresponding to the upper opening and closing chuck assembly 320.

[0073] The described head device 300 further includes: a lower mounting plate 302 and a moving connecting plate 303. The rotation drive assembly 340 is mounted on the moving connecting plate 303, and the lower mounting plate 302 and the upper moving plate 301 are connected by guide rods; such that after the entire head device 300 can be assembled into a whole, it can be additionally installed in the frame 100, and the overall assembly is more rapid.

[0074] The described rotation drive assembly 340 has a rotation shaft 341 and a motor group 342. The rotation shaft 341 is vertically arranged. One end of the rotation shaft 341 is connected to the motor group 342, and the other end passes through the moving connecting plate 303 and the upper moving plate 301 and is then connected to the mold core 313. The mold core 313 is driven to rotate by the rotation shaft 341, and then the entire mold assembly 310 is driven to rotate.

[0075] The described motor group 342 includes: a stepping motor 3421 and a speed reducer 3422; optionally, the output shaft of the speed reducer 3422 and the rotation shaft 341 are connected by a coupling.

[0076] A demolding assembly 350 is also installed on the head device 300. The demolding assembly 350 includes: a moving lower demolding plate 351 coaxially arranged with the rotation shaft 341, a motor 352, a belt assembly 353, and a demolding rod 354. The motor 352 drives the demolding rod 354 to move upward through the belt assembly 353, and then pushes the moving lower demolding plate 351 to move up and down along the rotation shaft 341 for demolding.

[0077] Specifically, please refer to Figure 4 and Figure 10 As shown, the described belt assembly 353 is installed at the bottom of the lower mounting plate 302. The belt assembly 353 has a plurality of driving belt pulleys and a driving belt. The driving belt is connected to the driving belt pulleys and drives the driving belt pulleys to rotate. The motor 352 is installed on the lower mounting plate 302. One set of symmetric driving belt pulleys is connected with a lead screw 355. One end of the lead screw 355 is connected to the driving belt pulley, and the other end is rotatably connected to the upper moving plate 301. The lead screw 355 is driven to rotate by the driving belt pulley; a lead screw connecting block 356 is installed on the lead screw 355, and the lead screw connecting block 356 is driven to move up and down by the lead screw 355;

[0078] The lead screw connecting block 356 is connected with a demolding rod 354. The demolding rod 354 is connected to the moving lower demolding plate 351. When the demolding rod 354 moves upward, it drives the moving lower demolding plate 351 to push the cross-flow air wheel upward for demolding; after demolding, the belt assembly 353 drives the moving lower demolding plate 351 to reset.

[0079] Further, when the wind turbine blade is assembled, the wind turbine blade is inserted into the insert groove 3121 and inserted downward through the mold sleeve 311 to the moving lower demolding plate 351.

[0080] Further, the moving connecting plate 303 is also installed through the guide rod. The moving connecting plate 303 is located between the upper moving plate 301 and the lower mounting plate 302, and a hand rocker 304 is connected to the moving connecting plate 303.

[0081] In one embodiment, please refer to Figures 7-8 As shown, the upper opening and closing chuck assembly 320 is installed on the upper moving plate 301 and is evenly distributed in multiple groups around the mold sleeve 311. In this embodiment, three groups are evenly distributed.

[0082] The upper opening and closing chuck assembly 320 includes: a bracket 321, an opening and closing chuck 322, and two groups of driving cylinders 323; the bracket 321 is fixed to the upper moving plate 301, and the specific structure of the bracket 321 is not limited as long as it can be fixedly installed on the upper moving plate 301; a slide rail 3211 is provided on the bracket 321.

[0083] The opening and closing chuck 322 has a clamping portion 3221. The opening and closing chuck 322 has two pivot points, and the opening and closing chuck 322 realizes swinging through the cooperation of two groups of driving cylinders 323.

[0084] As Figure 7 shown, the opening and closing chuck 322 is in an unfolded state. When a clamping action needs to be performed, through the cooperation of two groups of driving cylinders 323, the opening and closing chuck 322 is pushed to swing and clamp. After swinging, as Figure 8 shown; and, after the opening and closing chuck 322 swings, it corresponds to the slot 3111 of the mold sleeve 311 and acts on the fixing ring.

[0085] Specifically, since the present invention is used for assembling a large-sized cross-flow wind turbine, in addition to the fixing rings at the top and bottom of the cross-flow wind turbine, a middle fixing ring should also be provided in the middle. During the process of automated production, at least 3 fixing rings are pre-installed on the top of the mold assembly 310. As Figure 3 shown, seven fixing rings are installed on the mold assembly 310; the seven fixing rings are stacked.

[0086] When inserting the blades, the wind turbine blades pass through seven fixed rings and the blade insertion slots 3121 of the mold assembly 310 at one time and are inserted downward. After the wind turbine blades are inserted, their lower ends are supported on the movable lower stripping plate 351. Then, the clamping ring assembly 330 clamps multiple wind turbine blades. Between the highest fixed ring and the wind turbine blades, riveting is performed through the rolling riveting device 200. Then, the upper opening and closing chuck assembly 320 operates to clamp the fixed rings that have not been roll-riveted (i.e., except for the highest fixed ring). Then, the motor 352 drives the stripping rod 354 to move upward through the belt assembly 353, thereby pushing the movable lower stripping plate 351 to move upward along the rotating shaft 341, driving the wind turbine blades to move upward. During the upward movement of the wind turbine blades, not all the fixed rings will move upward synchronously. Through the clamping of the fixed rings by the upper opening and closing chuck assembly 320, after a certain distance, a fixed ring at a high position is released, so that the fixed ring at a high position rises synchronously with the wind turbine blades. Finally, the fixed rings on the mold assembly 310 can be evenly distributed on the wind turbine blades to form a cross-flow wind turbine.

[0087] In one embodiment, two sets of the clamping ring assemblies 330 are arranged below the upper moving plate 301 and the large panel 310, and the two sets of clamping ring assemblies 330 are vertically distributed and have the same structure.

[0088] As Figure 9 shown, the clamping ring assembly 330 includes: a plurality of clamping ring parts 331 distributed on the same plane and a driving device 332 that drives the clamping ring parts 331 to move closer to or away from each other. A complete circular clamping ring is formed between the plurality of clamping ring parts 331 to circumferentially surround the outer periphery of the cross-flow wind turbine.

[0089] Specifically, the clamping ring part 331 is arc-shaped, and the inner wall of the clamping ring part 331 is an inclined surface, protruding obliquely from top to bottom towards the center of the circle. When the rotating driving device 340 drives the mold assembly 310 to rotate, the clamping ring part 331 can prevent the wind turbine blades from swinging outward due to centrifugal deviation caused by the excessive length of the wind turbine blades, so as to affect production.

[0090] The driving device 332 includes: a mounting bracket 3321 mounted on a guide rod between the upper moving plate 301 and the lower mounting plate 302 and a driving cylinder 3322. The driving cylinder 3322 is connected to the clamping ring part 331 to drive the plurality of clamping ring parts 331 to move closer to or away from each other. When they move closer, a complete clamping ring is formed between the plurality of clamping ring parts 331.

[0091] Further, the clamping ring part 331 and the driving cylinder 3322 can be connected through a connecting member.

[0092] Further, on one plane, four identical clamping ring assemblies 330 are provided, so that a complete clamping ring can be formed during operation.

[0093] In one embodiment, the frame 100 is provided with a loading station and a rolling riveting station, and the head device 300 can switch between the loading station and the rolling riveting station by external force to complete the loading and rolling riveting actions;

[0094] Specifically, the head device 300 can be driven and moved by the horizontal moving device 360 ​​to switch between the loading station and the rolling riveting station; the horizontal moving device 360 ​​can include a horizontal slide rail 361 and a driving cylinder 362, the bottom of the upper moving plate 301 is installed on the horizontal slide rail 361 through a slider, and the horizontal slide rail 361 is installed on the large panel 110. At the same time, a space for the head device 300 to move is reserved on the large panel 110.

[0095] In one embodiment, see Figures 11-14 As shown in FIG. 1 , the rolling riveting device 200 is installed above the head device 300. The rolling riveting device 200 is driven by a rolling riveting driving device 500 to move up and down as a whole, and adjust the distance relative to the mold assembly 310 to facilitate the rolling riveting action.

[0096] The rolling riveting device 200 comprises: an upper mounting plate 201 as a carrier of the entire rolling riveting device 200, an upper bearing assembly 210, a guide plate 220, a guide plate 230, an upper belt transmission assembly 240 and a rolling riveting assembly 250;

[0097] The rolling riveting drive device 500 includes an upper mounting bracket 501 and a belt transmission assembly 510. The upper mounting bracket 501, the upper mounting plate 201 and the large panel 110 are connected by guide rods. The rolling riveting drive device 500 drives the upper mounting plate 201 to move up and down along the guide rods to adjust the distance between the rolling riveting device 200 and the mold assembly 310.

[0098] The upper bearing assembly 210 has a cross bearing 211, the outer ring of which is fixedly mounted on the bottom of the upper mounting plate 201; the upper belt transmission assembly 240 includes: a large pulley 241 fixed to the inner ring of the cross bearing 210, a belt 242 and a motor 243, and the large pulley 241 is driven to rotate by the motor 243.

[0099] The guide plate 220 is mounted on the bottom of the large belt pulley 241 and is driven to rotate by the large belt pulley 241.

[0100] The rolling riveting assembly 250 includes: a rolling riveting guide block 251 fixedly mounted on the guide plate 220 and located on the outer circumference of the guide track plate 230, a rolling riveting limit block 252 located on the outer circumference of the guide track plate 230, a guide rail 253 mounted on the bottom surface of the guide track plate 230, a slider mounted on the guide rail 253, and a rolling riveting wheel 254. ​​​​​​

[0101] A track groove 221 is provided on the guide disc 220, and a bearing member 231 is provided on the guide rail disc 230. The bearing member 231 is clamped into the track groove 221 and can move along the track groove 211. During use, the upper belt transmission assembly 240 drives the upper bearing assembly 210 and the guide disc 220 to rotate synchronously, so that relative rotation can occur between the guide disc 220 and the guide rail disc 230. Interference exists between the roll riveting guide block 251 and the roll riveting limit block 252, restricting the relative rotation angle between the guide disc 220 and the guide rail disc 230.

[0102] Then, by driving the guide disc 220 to rotate through the upper belt transmission assembly 240, the specific position of the roll riveting wheel 254 can be adjusted to adapt to roll riveting of cross-flow air wheels with different diameters.

[0103] Further, three groups of the roll riveting assemblies 250 are evenly assembled at the bottom of the guide rail disc 230.
