Description

Technical Field

[0001] The invention relates to the technical field of winding equipment, in particular to a power transformer winding equipment. Background Art

[0002] Winding is a crucial step in transformer production. Traditional transformer winding equipment typically uses simple fixed structures to secure the transformer for winding operations. However, these fixed structures often have numerous shortcomings, impacting winding efficiency and transformer quality.

[0003] Specifically, when the traditional fixing structure fixes the transformer, the spacing adjustment of the fixing parts and the winding process are independently controlled by two different drive units, which requires high control accuracy and has a relatively complex structure. In addition, since the spacing of the fixing parts is generally not further adjusted after adjustment, the winding process cannot be dynamically adjusted, that is, dynamically tightened.

[0004] Furthermore, after winding is completed, traditional winding equipment requires manual removal of the transformer for the next winding cycle. This process is not only time-consuming and labor-intensive, but also makes it difficult to quickly switch between wound and unwound transformers, impacting the continuity and efficiency of the production line.

[0005] Based on this, a power transformer winding device is now provided to eliminate the disadvantages of the existing devices. Summary of the Invention

The end of each bevel gear 2 away from bevel gear 1 is fixedly connected to a bevel gear 3 through a rotating rod. Bevel gear 3 is meshed with bevel gear 4. The rear end of bevel gear 4 is rotatably connected to the inner wall of the rotating box through fixed rod 2, and the front end of bevel gear 4 is connected to the moving structure.

[0009] Preferably, a fixing rod 1 is symmetrically fixed on the left and right sides of the inner wall of the rotating box, and the fixing rod 1 is fixedly connected to the fixing cylinder. The inner wall of the fixing cylinder rotates with the outer wall of the rotating rod. One end of the fixing cylinder abuts against the second bevel gear, and the other end of the fixing cylinder abuts against the third bevel gear.

[0010] Preferably, two movable grooves are symmetrically provided at the front end of the rotating frame, and an installation cavity is provided inside the rotating frame, and the installation cavity is located between the two movable grooves and is connected to the inside of the two movable grooves; a movable structure for adjusting the relative distance between the two fixing parts is provided inside the installation cavity and the two movable grooves, and the movable structure is connected to the fixing part.

The front end of the connecting rod 1 extends into the installation cavity and is fixedly connected to the bevel gear 5, and the bevel gear 5 is meshed and connected to the bevel gear 6.

[0012] Preferably, the bevel gear six is fixed to the connecting rod two, and the upper and lower ends of the connecting rod two respectively extend to the inside of two movable grooves to fix two screws, the two screw threads have opposite directions, and the screw threads are connected to the moving block, the moving block is slidably installed in the movable groove, and the front end of the moving block is connected to the fixed part.

Since the screw threads have opposite directions, the two moving blocks can move synchronously relative to or in opposite directions, thereby integrating the drive unit, simplifying the control structure, and reducing the requirements for control accuracy, thereby solving the control complexity problem caused by two independent drive units controlling the spacing between fixed parts and the winding process in traditional equipment.

[0017] 2. This invention uses a motor-driven gear to mesh with the gear ring, rotating the rotating box 180 degrees and swapping the positions of the two rotating frames and fixed parts. When the right-hand moving block moves away, the support plate presses against the inner wall of the transformer to secure it, facilitating winding. When the left-hand moving block moves closer, the support plate releases the transformer, facilitating removal. This design enables dynamic tightening during the winding process, improving winding efficiency.

[0018] 3. The present invention cooperates with the movable structure through the fixing part. When the transformer needs to be fixed, the support plates can be synchronously moved away from each other through the driving of the movable structure, tightly pressed against the inner wall of the transformer, and stable and reliable fixation is achieved. This fixing method avoids the problems of looseness or loose fixation that may exist in traditional fixing structures, ensuring the smooth progress of the winding process; and the support plate is provided with a rubber pad at the end away from the limit rod, which increases the stability of the support and prevents the support plate from scratching or damaging the inner wall of the transformer.

[0025] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In one embodiment, Figure 1-Figure 5 As shown, a power transformer winding device includes a housing 1, a rotating box 2 and a gear 12 are rotatably mounted inside the housing 1, a gear ring 21 is fixed to the outer wall of the rotating box 2, and the gear ring 21 is meshed with the gear 12; A motor 11 is installed at the rear end of the housing 1, and the output end of the motor 11 extends into the interior of the housing 1 and is fixedly connected to a gear 12; Two sets of rotating frames 4 are symmetrically installed at the front end of the rotating box 2. A fixing member 6 for fixing the transformer is installed in the middle of the front end of each set of rotating frames 4. Two movable grooves 41 are symmetrically opened at the front end of the rotating frame 4. An installation cavity is opened inside the rotating frame 4. The installation cavity is located between the two movable grooves 41 and is connected to the inside of the two movable grooves 41. A movable structure 5 for adjusting the relative distance between the two fixing members 6 is provided inside the installation cavity and the two movable grooves 41. The movable structure 5 is connected to the fixing members 6. A rotating structure 3 driving the rotating frame 4 to rotate is provided inside the rotating box 2 , and the rotating structure 3 is connected to the moving structure 5 .

[0026] In this embodiment, the transformer to be wound is first placed outside the fixing member 6, and then the rotating structure 3 drives the moving structure 5 to operate, and the moving structure drives the fixing member 6 to open, so that the fixing member 6 is pressed against the inner wall of the transformer to fix it. After that, the torque can be transmitted normally to drive the transformer to rotate and realize winding. When the transformer winding is completed by the right fixing part 6, the gear 12 is driven to rotate by the motor 11, and then the rotating box 2 is driven to rotate inside the shell 1. The positions of the two sets of rotating frames 4 and the fixing part 6 are exchanged. The transformer with completed winding is removed and the transformer with unfinished winding continues to be wound without stopping the machine, saving time.

[0027] In an optional embodiment, the rotating structure 3 includes a bevel gear 1 32 rotatably mounted at the center of the rotating box 2 and a motor 2 31 mounted at the rear end of the housing 1; The output end of the motor 2 31 extends to the inside of the rotating box 2 and is fixedly connected to the bevel gear 1 32. The left and right sides of the bevel gear 1 32 are symmetrically meshed with two bevel gears 2 33. The end of each bevel gear 2 33 away from the bevel gear 1 32 is fixedly connected to a bevel gear 3 35 through a rotating rod 34. The bevel gear 3 35 is meshed with a bevel gear 4 36. The rear end of the bevel gear 4 36 is rotatably connected to the inner wall of the rotating box 2 through the fixed rod 2 24, and the front end of the bevel gear 4 36 is connected to the moving structure 5.

[0028] It should be noted that, since the two bevel gears 2 33 are respectively located on both sides of the bevel gear 1 32, the two bevel gears 2 33 rotate in opposite directions. Gradually, it is deduced that the two bevel gears 4 36 rotate in opposite directions, which makes the two bevel gears 4 36 rotate in opposite directions, and the operating results of the moving structures 5 corresponding to the two bevel gears 4 36 are opposite.

[0029] In an optional embodiment, fixed rods 22 are symmetrically fixed on the left and right sides of the inner wall of the rotating box 2. The fixed rod 22 is fixedly connected to the fixed cylinder 23. The inner wall of the fixed cylinder 23 rotates with the outer wall of the rotating rod 34. One end of the fixed cylinder 23 abuts against the bevel gear 2 33, and the other end of the fixed cylinder 23 abuts against the bevel gear 3 35.

[0030] It should be noted that the fixing rod 1 22 and the fixing cylinder 23 provide stable support and positioning for the bevel gear 2 33 , the bevel gear 3 35 and the rotating rod 34 , thereby ensuring the accuracy and reliability of the gear transmission.

[0031] In an optional embodiment, two movable grooves 41 are symmetrically provided at the front end of the rotating frame 4, and an installation cavity is provided inside the rotating frame 4. The installation cavity is located between the two movable grooves 41 and is connected to the interior of the two movable grooves 41; a movable structure 5 for adjusting the relative distance between the two fixing parts 6 is provided inside the installation cavity and the two movable grooves 41, and the movable structure 5 is connected to the fixing part 6.

[0032] Among them, the movable structure 5 includes a connecting rod 51, which is fixed at the front end of the bevel gear 4 36. The front end of the connecting rod 51 extends to the inside of the mounting cavity and is fixedly connected to the bevel gear 5 52. The bevel gear 5 52 is meshed with the bevel gear 6 53.

[0033] The bevel gear six 53 is fixed to the connecting rod two 54, and the upper and lower ends of the connecting rod two 54 extend to the inside of the two moving grooves 41 to be fixedly connected to two screws 55. The thread directions of the two screws 55 are opposite, and the screws 55 are threadedly connected to the moving block 56. The moving block 56 is slidably installed in the moving groove 41, and the front end of the moving block 56 is connected to the fixed part 6.

[0034] It should be noted that bevel gear four 36 drives bevel gear five 52 to rotate through connecting rod one 51, thereby driving bevel gear six 53 to rotate, and bevel gear six 53 drives two screws 55 to rotate respectively inside the moving groove 41 where they are located through connecting rod two 54. Since the two screws 55 have opposite thread directions but the same rotation direction, the two moving blocks 56 move synchronously in relative or opposite directions under the action of the two screws 55, thereby driving the fixed opening or contraction.

[0035] In an optional embodiment, the fixing member 6 includes a limit rod 61 rotatably installed in the middle of the rotating frame 4, and the limit block 2 63 and the limit block 1 62 are fixed at the front end and the middle of the limit rod 61 respectively, and sliding blocks 64 are slidably provided on the outer walls of both ends of the limit rod 61.

[0036] Among them, the fixing member 6 also includes two pairs of fixing ears 65, and the two pairs of fixing ears 65 are respectively fixed on the upper and lower ends of the sliding block 64, each of the fixing ears 65 is hinged to one end of the connecting rod 66, and the other end of the connecting rod 66 is hinged to the fixing ear 2 67, and the fixing ear 2 67 is fixed to the middle of one end of the support plate 68 close to the limit rod 61, and the rear end of the support plate 68 is fixedly connected to the front end of the moving block 56.

[0037] A rubber pad is provided at one end of the support plate 68 away from the limiting rod 61 , and anti-slip grooves are provided on the surface of the rubber pad.

[0038] It should be noted that, by synchronously moving the two moving blocks 56 in relative or opposite directions, the two support plates 68 are synchronously moved closer to or farther away from each other, so that the fixing member 6 can adjust the spacing between the support plates 68 as needed to adapt to transformers with different inner diameters; the limit block 2 63 and the limit block 1 62 limit the sliding range of the sliding block 64 on the limit rod 61, ensuring that the sliding block 64 will not exceed the predetermined motion trajectory; the connecting rod 66 serves as a bridge connecting the sliding block 64 and the support plate 68, transmitting the moving torque of the sliding block 64 to the support plate 68, thereby realizing force transmission and conversion.

[0039] Rubber, due to its good elasticity, wear resistance and anti-slip properties, can increase the stability of the support; the anti-slip pattern can increase the friction between the rubber pad and the contact surface to prevent sliding.

[0040] The above embodiment discloses a power transformer winding device, wherein the transformer to be wound is placed on the outside of the fixing member 6, and the fixing member 6 is composed of a support plate 68, a sliding block 64, a connecting rod 66 and other components. In the initial state, the spacing between the support plates 68 is moderate and the transformer is not fixed.

[0041] Start motor 2 31, and its output end drives bevel gear 1 32 to rotate. Bevel gear 1 32 is symmetrically meshed with two bevel gears 2 33 on the left and right sides, so that the two bevel gears 2 33 rotate in opposite directions. Gradually deducing, the two bevel gears 4 36 on the left and right sides rotate in opposite directions.

[0042] Bevel gear four 36 drives bevel gear five 52 to rotate through connecting rod one 51, and bevel gear five 52 then drives bevel gear six 53 to rotate, so that the two gears six 53 on the left and right sides rotate in opposite directions.

[0043] Bevel gear six 53 drives two screws 55 to rotate in the same direction inside the moving groove 41 where they are located through connecting rod two 54. Since the thread directions of the two screws 55 are opposite, the two moving blocks 56 move synchronously in relative or opposite directions under the action of the screws 55.

[0044] After winding the transformer on the right-hand mounting member 6 is complete, motor 11 is activated, driving gear 12. Gear 12 engages with ring gear 21, driving rotating box 2 to rotate 180 degrees within housing 1. After this rotation, the two sets of rotating frames 4, along with the mounting member 6, swap positions. The wound transformer is removed, and the unwound transformer is placed in the winding position.

[0045] Repeat the above operations of fixing, winding and changing positions to achieve a continuous and efficient transformer winding process.

[0046] Specifically, the two moving blocks 56 on the right side move synchronously in opposite directions under the action of the screw 55, thereby driving the support plate 68 to move away synchronously. When the support plate 68 is pressed against the inner wall of the transformer, the transformer is fixed and can transmit torque normally to drive the transformer to rotate and realize winding.

[0047] The two moving blocks 56 on the left side move synchronously relative to each other under the action of the screw 55, thereby driving the support plate 68 to move synchronously, so that the support plate 68 no longer presses against the inner wall of the transformer, and the transformer is no longer fixed, which is conducive to normal removal.

[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
