[0002] The fan frame is the core supporting component of the fan. Its structure is usually assembled and welded from multiple sections of bent wire circumference and two concentric rings of different sizes. In the industry, the welding of fan frames is still mainly done manually. After the fan frame is assembled, workers use welding guns to complete the welding. During welding, they need to frequently change their standing position in order to weld the wires in different positions. If the workers do not change their standing position, the fan frame needs to be rotated. The lack of positioning of the fan frame may cause the parts to slip during the rotation, which further reduces production efficiency. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1 Reference Figures 1-4This is the first embodiment of the present invention. This embodiment provides a fan frame welding device. The fan frame welding device includes a main component 1, including a worktable 11. A sliding table 12 is slidably disposed on the worktable 11. A slide rail 11-1 is fixed on the worktable 11. A slider 12-2 is disposed at the bottom of the sliding table 12. Through the cooperation of the slide rail 11-1 and the slider 12-2, the sliding table 12 can slide relative to the worktable 11. After welding is completed, a cylinder applies a pushing force to the sliding table 12, causing the sliding table 12 to protrude from the worktable 11, making it easier for the worker to remove the welded fan frame 15.
[0027] A frame 13 is fixed on the workbench 11, and a bending device 14 is fixed on the frame 13. The bending device 14 mainly consists of a feeding mechanism, an upper die, a lower die, and a driving mechanism. The upper die corresponds to the lower die. The long strip-shaped workpiece is placed on the lower die. The driving mechanism drives the upper die to move downward and engage with the lower die, thus bending the workpiece. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0028] A fan frame 15 is installed on the sliding table 12. The fan frame 15 needs to be erected before welding.
[0029] A moving mechanism 16 is also fixed on the frame 13, located on one side of the bending device 14. The moving mechanism 16 is used to transfer the bent workpiece to the placement base 211. The moving mechanism 16 has a movable and clamping mechanical arm.
[0030] Welding assembly 2, located on sliding table 12, includes support member 21. Support member 21 is provided to support support member 21. Welding member 22 is provided on one side of support member 21. Welding member 22 is the main part of welding. Resistance welding is used to weld the fan frame 15.
[0031] The support member 21 includes a placement base 211 located on the sliding table 12. A support ring 212 is provided at the bottom of the placement base 211. A support plate 213 is fixed on the support ring 212. The support plate 213 is fixed on the sliding table 12. There are four support plates 213, which are used to support the support ring 212. The fan frame 15 is placed on the support ring 212. The support ring 212 can provide auxiliary support for the fan frame 15 without affecting the subsequent rotation of the fan frame 15.
[0032] A rotary motor 214 is installed on the sliding table 12. The motor shaft of the rotary motor 214 is connected to the fan frame 15 by bolts, so that after the rotary motor 214 is started, it can drive the fan frame 15 to rotate synchronously.
[0033] The welding component 22 includes a welding cylinder 221 mounted on a sliding table 12. An electrode is mounted at the end of the welding cylinder 221, which can drive the electrode to move horizontally. A first welding torch 222 and a second welding torch 223 are mounted on the frame 13. The welding point of the first welding torch 222 is closer to the center of the fan frame 15, while the welding point of the second welding torch 223 is closer to the edge of the fan frame 15. A lifting cylinder is mounted on one side of the first welding torch 222 and the second welding torch 223. The two cylinders can sequentially move the two welding torches closer to or further away from the fan frame 15. Corresponding electrodes are mounted on the two welding torches. During welding, the welding cylinder 221 moves the electrodes on the torches to press against the fan frame 15. Then, one of the cylinders moves the first welding torch 222 downward to fit against the fan frame 15, completing one welding operation. Afterward, the first welding torch 222 is reset, and the cylinder moves the second welding torch 223 downward to complete the welding operation. Then, the rotary motor 214 drives the fan frame 15 to rotate, changing the position of the frame to be welded.
[0034] Example 2 Reference Figures 1-3 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0035] Specifically, the fan frame 15 includes wires 151, a large ring 152, and a small ring 153. The wires 151 and the small rings 153 are placed on a base 211. Six auxiliary blocks are fixed on the base 211 to limit the position of the small rings 153. There are a total of 12 wires 151, which are evenly distributed in a circular shape on the small rings 153 and the large rings 152. The two ends of each wire 151 need to be welded to the small rings 153 and the large rings 152 respectively. The welding point between the wires 151 and the small rings 153 is completed by the small rings 153, while the welding between the wires 151 and the large rings 152 is completed by the second welding gun 223. After the welding of one wire 151 is completed, the rotary motor 214 drives the fan frame 15 to rotate, change the frame position to be welded, and then weld the next wire 151.
[0036] A cylinder is provided on one side of the lower die of the bending device 14. The cylinder can drive the lower die to move away from the frame 13, so that the bent wire 151 on the lower die is aligned with the center of the placement base 211. Then, in conjunction with the robotic arm on the moving mechanism 16, the wire 151 is placed at the designated position on the placement base 211.
[0037] Specifically, a through groove 211-1 is provided on the placement base 211. The through groove 211-1 is used to position the wire 151. A first guide block 215 is fixed on the placement base 211, and a second guide block 216 is also fixed on the placement base 211. There are multiple first guide blocks 215 and second guide blocks 216. The first guide blocks 215 are arranged in pairs, with a total of 12 pairs, each corresponding to one wire 151. The number of second guide blocks 216 is the same as that of the first guide blocks 215. Through the arrangement of the first guide blocks 215 and second guide blocks 216, and in conjunction with the through groove 211-1, the position of the wire 151 on the placement base 211 can be restricted.
[0038] Specifically, the first guide block 215 is rectangular and the second guide block 216 is triangular. There is a gap between the first guide block 215 and the second guide block 216 in the same group, and the wire 151 can be placed in the gap.
[0039] Specifically, a connecting rod 217 is fixed below the base 211, an auxiliary plate 218 is fixed to one end of the connecting rod 217, and a support block 219 is fixed on the auxiliary plate 218. There are multiple connecting rods 217 and support blocks 219. The connecting rod 217 is used to connect the auxiliary plate 218 and the base 211 and to limit the wire 151. The support block 219 is L-shaped and is used to support the large ring 152.
[0040] After each wire 151 is placed, the rotary motor 214 drives the fan frame 15 to rotate by one unit angle to place another wire 151. This process continues until all 12 wires 151 are placed. Then, the small ring 153 is placed on the placement base 211, and the large ring 152 is placed on the support block 219. At this point, all the wires 151 are located inside the large ring 152.
[0041] Example 3 Reference Figures 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0042] Specifically, the large ring 152 is located on the support block 219, and the auxiliary plate 218 is also provided with through slots 211-1 for limiting the iron wire 151, the number of which corresponds to the iron wire 151.
[0043] Specifically, the welding assembly 2 also includes an auxiliary component 23 located on the sliding table 12. The auxiliary component 23 limits the position of the placed fan frame 15 and ensures that the position of each part of the fan frame 15 will not shift during welding when the rotary motor 214 drives the placement base 211 to rotate.
[0044] The auxiliary component 23 includes a movable plate 231 located on one side of the base 211. A first extrusion plate 232 and a second extrusion plate 233 are fixed on the movable plate 231. The first extrusion plate 232 and the second extrusion plate 233 have a certain angle between them. The first extrusion plate 232 is located closer to the sliding table 12 than the second extrusion plate 233. A cylinder is provided on one side of the movable plate 231. The cylinder can drive the movable plate 231 to move. The cylinder has a certain tilt angle when installed. Two clamps 237 are provided outside the cylinder. A support frame 238 is fixed on each of the two clamps 237. The two support frames 238 have different lengths, so that the cylinder is fixed on the sliding table 12 at a certain angle. A support platform 239 is fixed at the bottom of the support frame 238. The support platform 239 is fixed to the sliding table 12.
[0045] When the moving mechanism 16 places a wire 151 on the placement base 211, the rotary motor 214 rotates by a unit angle, and the cylinder on one side of the moving plate 231 is activated, causing the moving plate 231 to move closer to the wire 151. The first pressing plate 232 will contact the more vertical part of the wire 151, while the second pressing plate 233 will contact the relatively horizontal part of the wire 151, applying a pushing force to the wire 151 from two directions to ensure that the wire 151 is completely located in the through groove 211-1, and at the same time moving the wire 151 towards the center of the placement base 211, ensuring that each wire 151 can be placed in the accurate position.
[0046] Specifically, a controller 234 is fixed on the sliding table 12. A rotating plate 235 is rotatably mounted on the controller 234. The controller 234 can drive the rotating plate 235 to rotate. A pulley 236 is provided at one end of the rotating plate 235. In the initial state, the rotating plate 235 is in an upward tilted position. When welding is required, the controller 234 causes the rotating plate 235 to rotate downward, causing the pulley 236 to move above the support block 219 and closely fit with the large ring 152 located above the support block 219, applying a downward thrust to the large ring 152, thereby making the large ring 152 closely fit with the support block 219 and limiting the position of the large ring 152. The setting of the pulley 236 will not affect the rotation of the large ring 152.
[0047] Specifically, there are four controllers 234 and four pulleys 236.
[0048] Specifically, a vertical limiting mechanism 17 is fixed on the frame 13. Before welding, a circular insulating limiting plate needs to be placed in the center of the placement base 211. The size of the limiting plate corresponds to the small ring 153. The cylinder in the vertical limiting mechanism 17 will drive the limiting column to move downward. An insulating pad is fixed at the end of the limiting column. The insulating pad applies a downward thrust to the fan flange, while limiting the small ring 153 and the wire 151 near one end of the small ring 153 from moving during the welding process.
[0049] In use, the bending device 14 bends the wire 151, and the moving mechanism 16 transfers the bent wire 151 to the placement base 211. At this time, the wire 151 will be located in the through groove 211-1. The first guide block 215 and the second guide block 216 assist in positioning the wire 151. Then, the rotating motor 214 drives the fan frame 15 to rotate by one unit angle to place another wire 151.
[0050] After the rotary motor 214 rotates by a unit angle, the cylinder on one side of the moving plate 231 will be activated, causing the moving plate 231 to move closer to the wire 151. The first pressing plate 232 will contact the relatively vertical part of the wire 151, while the second pressing plate 233 will contact the relatively horizontal part of the wire 151, applying a pushing force to the wire 151 from two directions to ensure that the wire 151 is completely located in the through groove 211-1, while moving the wire 151 towards the center of the placement base 211, ensuring that each wire 151 can be placed in the accurate position.
[0051] After all the wires 151 have been placed, place the small ring 153 on the base 211, and then place the large ring 152 on the support block 219. At this point, all the wires 151 are inside the large ring 152.
[0052] Then, controller 234 causes rotating plate 235 to rotate downwards, moving pulley 236 above support block 219 and tightly fitting it against large ring 152 located above support block 219, applying a downward thrust to large ring 152, thus tightly fitting large ring 152 against support block 219, limiting the position of large ring 152, placing limiting plate and setting vertical limiting mechanism 17 to limit small ring 153, welding cylinder 221 drives its electrodes to adhere to fan frame 15, and then one of the cylinders drives the first The welding torch 222 moves downward and comes into contact with the fan frame 15 to complete one welding operation. After that, the first welding torch 222 returns to its original position, and the cylinder drives the second welding torch 223 to move downward to complete the welding operation. Then, the rotary motor 214 drives the fan frame 15 to rotate, changing the position of the frame to be welded, until all the wires 151 are welded. The cylinder applies a pushing force to the sliding table 12, causing the sliding table 12 to protrude from the worktable 11, making it easier for the worker to remove the welded fan frame 15. In this way, the production capacity of fan frames is increased through semi-automatic equipment.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
