[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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.

[0022] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown: A welding structure of a fan casing processing and assembly equipment, comprising an equipment frame 1 with an opening on the side, a fixing component 2 extending from the opening is fixedly installed on the inner wall of the equipment frame 1, a supporting component 3 for supporting a welded part is fixedly installed on the bottom of the equipment frame 1, the supporting component 3 is located directly below the fixing component 2, and a welding device 4 is fixedly installed at one end of the fixing component 2; The fixing assembly 2 includes a first hook rod 25 and a second hook rod 29 which are symmetrically distributed up and down, four connecting gears 24 which are arranged in a horizontal state, a first electric cylinder 22 and two transmission rods 27 for transmitting power. The two first hook rods 25 and the two second hook rods 29 are staggered and symmetrically distributed along the center line of the equipment frame 1 to form an X shape; One end of the first hook rod 25 and one end of the second hook rod 29 are both fixedly connected to a gear rod 26, and both sides of each transmission rod 27 are meshedly connected to a connecting gear 24, and the other side of the connecting gear 24 is meshedly connected to the gear rod 26; The angle between the transmission rod 27 and the gear rod 26 is set at 30-80°. The first electric cylinder 22 is located between the two transmission rods 27. When in use, the transmission rod 27 drives the gear rod 26 through the connecting gear 24, and at the same time pulls the first hook rod 25 and the second hook rod 29 to move alternately, pulling the arc panel structure to the center line of the welding equipment 4.

[0023] In this embodiment, the equipment frame 1 is used to determine the position of each component, and an opening is provided on one side thereof for the fixing component 2 to move. The fixing component 2 is used to fix the casing components of the fan. When in use, the bottom of the component is supported by the supporting component 3, and the fixing component 2 pulls the component toward the welding device 4. After the position of the component is determined, the welding device 4 welds the components together. The first hook rod 25 and the second hook rod 29 are distributed in the equipment frame 1 in a vertically symmetrical state. When in use, the first hook rod 25 fixes the upper half of the component, and the second hook rod 29 hooks the lower half of the component, so as to fully fix the component; The first hook rod 25 and the second hook rod 29 have the same structure, both being an X-shaped staggered structure. When fixing components, the first electric cylinder 22 simultaneously pushes two transmission rods 27. The transmission rods 27 mesh with the toothed rods 26 through the connecting gears 24 to achieve the purpose of pushing the first hook rod 25 and the second hook rod 29. The first hook rod 25 and the second hook rod 29 move towards the inside of the equipment frame 1, hook the components and push them near the welding equipment 4; During the welding process, the fixing component 2 and the bottom support component 3 are used in cooperation at the same time to fix and support components such as the arc-shaped panel, and can maintain the stability of the arc-shaped panel during the welding process, so as to ensure the welding quality; After welding two arc-shaped panels together, the first hook rod 25 and the second hook rod 29 expand again to expose more space to accommodate the third arc-shaped panel. At this time, the already welded arc-shaped panel can still be顶住 by the first hook rod 25 and the second hook rod 29, and the stability of the components can continue to be maintained.

[0024] Embodiment 2: According to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the fixing component 2 further includes a vertical plate 21. The vertical plate 21 is fixedly installed on the inner wall of the equipment frame 1. The first electric cylinder 22 is fixedly installed inside the vertical plate 21. The first electric cylinder 22 is perpendicular to the vertical plate 21. Horizontal plates 28 are fixedly installed at both the upper and lower ends of the vertical plate 21. The cross-section of the horizontal plate 28 is Y-shaped; The cross-section of the combination of the horizontal plate 28 and the vertical plate 21 is C-shaped; One end of the piston rod of the first electric cylinder 22 is rotatably connected with a roller 23. The roller 23 is vertically located between the two horizontal plates 28. Tooth plates 210 are fixedly installed on the opposite sides of the two transmission rods 27. The two tooth plates 210 are symmetrically distributed on the upper and lower sides of the roller 23 and are both meshed with the roller 23; Positioning protrusions 212 are fixedly installed on the surface of the bent part of the horizontal plate 28. The first hook rod 25 is slidably connected inside the positioning protrusions 212. One end of the transmission rod 27 is fixedly installed with a limiting rod 211. The cross-section of the combination of the limiting rod 211 and the transmission rod 27 is T-shaped; The tooth plate 210 is slidably connected inside the horizontal plate 28. A strip-shaped hole 213 is opened at the junction of the horizontal plate 28 and the tooth plate 210. A positioning block 214 is arranged at the junction of the horizontal plate 28 and the strip-shaped hole 213. The transmission rod 27 is slidably connected inside the positioning block 214.

[0025] In this embodiment, the vertical plate 21 is installed on the inner wall of the equipment frame 1, and the horizontal plates 28 at the upper and lower ends thereof can determine the positions of the first hook rod 25 and the second hook rod 29. The horizontal plate 28 and the vertical plate 21 are in a U-shaped structure, which can ensure the structural stability of the first hook rod 25 and the second hook rod 29, and can ensure that the piston rod in the first electric cylinder 22 has sufficient activity space; When the piston rod in the first electric cylinder 22 is extended, since the two tooth plates 210 are symmetrically distributed on the upper and lower sides of the roller 23, and each tooth plate 210 is connected with a transmission rod 27, the transmission rod 27 is in the horizontal plate 28, and the ends of the two tooth plates 210 are both against the vertical plate 21, therefore, when the first electric cylinder 22 pushes the roller 23, the two tooth plates 210 are meshed with the roller 23, and the roller 23 cannot rotate at this time. At this time, the roller 23 will push the two tooth plates 210 at the same time. The tooth plates 210 are fixedly connected with the transmission rod 27. During the movement of the tooth plates 210, the transmission rod 27 will be driven to move, and the transmission rod 27 will push the connecting gear 24. The rotation of the connecting gear 24 will push the tooth rod 26, so as to achieve the purpose of pushing the first hook rod 25 and the second hook rod 29; If the first hook rod 25 hooks onto the housing component and the second hook rod 29 does not hook onto the component, the movement of the first hook rod 25 will be blocked, and the tooth plate 210 corresponding to the first hook rod 25 will stop moving. In this case, the first electric cylinder 22 continues to push the roller 23, and the tooth plate 210 in a stationary state will engage the roller 23 to make it rotate, and the roller 23 will then engage the tooth plate 210 corresponding to the second hook rod 29, so as to continue to push the second hook rod 29. This method can ensure that the fixing assembly 2 can adapt to curved panels with different structures. The positioning protrusion 212 is installed at the bending part of the horizontal plate 28, and is used to determine the moving route of the first hook rod 25 and the second hook rod 29 to avoid the problem of structural misalignment. The limit rod 211 set at the end of the transmission rod 27 is used to determine the maximum moving range of the transmission rod 27 to ensure that the final stop position of the component is near the welding device 4; The strip hole 213 is used to accommodate the tooth plate 210 and determine its moving route, thereby ensuring the stability of the tooth plate 210 during movement. Together with the positioning block 214 at the edge of the strip hole 213 , it can play a role in determining the moving route of the transmission rod 27 .

[0026] Embodiment 3: According to Figure 2 , Figure 3 and Fig. 9 As shown, the support assembly 3 includes a receiving platform 31 and a second electric cylinder 32. The second electric cylinder 32 is fixedly installed at the bottom of the equipment frame 1 in a vertical state, and the receiving platform 31 is located below the welding equipment 4; A bending rod 33 is rotatably connected to the bottom of the receiving platform 31, and one end of the bending rod 33 is rotatably connected to one end of the piston rod of the second electric cylinder 32; A vertical rod 34 is fixedly mounted on the lower surface of the equipment frame 1 , and the corner of the bending rod 33 is rotatably mounted on the bottom of the vertical rod 34 .

[0027] In this embodiment, the second electric cylinder 32 is fixedly installed in a vertical state at the bottom of the equipment frame 1, and is used to control the angle of the bending rod 33. When in use, when the piston rod in the second electric cylinder 32 is extended, it will push the bending rod 33 to rotate with the bottom of the vertical rod 34 as the center, so that the receiving platform 31 moves upward to achieve the purpose of adjusting the height of the parts. The vertical rod 34 is installed on the lower surface of the equipment frame 1, and is used to determine the position and rotation center of the bending rod 33. The existence of the vertical rod 34 allows the bending rod 33 to have sufficient room for movement.

[0028] Embodiment 4: According to Figure 4 , Figure 5 and Figure 8 As shown, the welding device 4 includes a guide rod 41 and an electric welding head 42. The electric welding head 42 is slidably installed inside the guide rod 41. A vertical hole 43 is opened at the intersection of the guide rod 41 and the electric welding head 42. A connecting block 45 is fixedly installed on the side of the electric welding head 42, and the connecting block 45 is embedded in the inside of the guide rod 41. A pinion 46 is rotatably mounted on one side of the engagement block 45; One side of the guide rod 41 is fixedly connected to two support rods 44, and the two support rods 44 are fixedly installed between the two horizontal plates 28; The pinion gear 46 is located inside the vertical hole 43 . A convex tooth 47 is fixedly mounted on a side wall of the vertical hole 43 . The pinion gear 46 is meshedly connected with the convex tooth 47 .

[0029] In this embodiment, the support rod 44 on the side of the guide rod 41 is fixedly installed between two adjacent horizontal plates 28 to ensure its own structural stability. The electric welding head 42 is slidably installed on the guide rod 41, and its wiring terminal is connected to the external power supply. A connecting block 45 is provided on the side of the electric welding head 42, and a micro motor is provided inside the connecting block 45 for driving a pinion 46. The wiring terminal of the micro motor is connected to the wiring terminal of the electric welding head 42; The micro motor drives the pinion 46, and the pinion 46 cooperates with the convex teeth 47 on the inner wall of the vertical hole 43 to drive the connecting block 45 to move along the length direction of the vertical hole 43. The welding head 42 moves along the length direction of the guide rod 41, and welding is performed from top to bottom or from bottom to top to obtain better stability and sufficient movement range.

[0030] The use method and working principle of the device: When in use, the bottom of the component is supported by the support component 3, and the fixing component 2 pulls the component to the welding device 4. After the position of the component is determined, the welding device 4 welds the components together; When fixing the casing parts, the first electric cylinder 22 pushes the two transmission rods 27 at the same time, and the transmission rod 27 drives the gear rod 26 to move through the connecting gear 24, so as to push the first hook rod 25 and the second hook rod 29. The first hook rod 25 and the second hook rod 29 move toward the inside of the equipment frame 1, hook the parts and push them to the vicinity of the welding equipment 4; When the piston rod in the first electric cylinder 22 extends, the roller 23 will push the two tooth plates 210 at the same time. The tooth plates 210 are fixedly connected to the transmission rod 27. When the tooth plates 210 move, they will push the connecting gear 24. The rotation of the connecting gear 24 will drive the tooth rod 26 to move, thereby pushing the first hook rod 25 and the second hook rod 29. If the first hook rod 25 hooks onto the housing component and the second hook rod 29 does not hook onto the component, the movement of the first hook rod 25 will be blocked, and the tooth plate 210 corresponding to the first hook rod 25 will stop moving. In this case, the first electric cylinder 22 continues to push the roller 23, and the tooth plate 210 in a stationary state will engage the roller 23 to make it rotate, and the roller 23 will then engage the tooth plate 210 corresponding to the second hook rod 29, so as to continue to push the second hook rod 29. This method can ensure that the fixing assembly 2 can adapt to curved panels with different structures. When the support assembly 3 is used, the extension of the piston rod in the second electric cylinder 32 will push the bending rod 33 to rotate with the bottom of the vertical rod 34 as the center, so that the receiving platform 31 moves upward to achieve the purpose of adjusting the height of the component; Finally, a micro motor driving pinion 46 is arranged inside the connecting block 45. The pinion 46 cooperates with the convex teeth 47 on the inner wall of the vertical hole 43 to drive the connecting block 45 to move along the direction of the vertical hole 43. The electric welding head 42 moves along the direction of the guide rod 41 to perform welding from top to bottom or from bottom to top. After the two curved panels are welded together, the first hook rod 25 and the second hook rod 29 are unfolded again to expose more space to accommodate the third curved panel.
