Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and more specifically, to a transformer winding device. Background Technology

[0002] Electronic transformers are a new type of power conversion device that possesses the voltage transformation, electrical isolation, and energy transfer functions of traditional power transformers. Currently, the larger the transformer capacity on the market, the greater its impact on the power grid, and the higher the requirements for its safety. For transformers, not only reliable electrical performance is required, but also more reliable mechanical stability and short-circuit withstand capability.

[0003] Existing transformer winding equipment typically clamps the transformer by squeezing from both ends or clamping from a single end. The squeezing from both ends method requires alignment with the center position during clamping, resulting in a long clamping operation time. Moreover, this clamping method can cause the transformer position to shift due to vibrations from the working mechanical structure such as the motor during winding, thus affecting the accuracy of winding. In view of this, we propose a transformer winding device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a transformer winding device to solve the technical problem that the current method of squeezing and clamping at both ends will cause the clamping position to shift during the winding process.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a transformer winding device, comprising a winding device body composed of a main frame, a wire feeding component, a tensioning component, a wire pushing component, and a winding component;

[0006] The winding component includes a drive component and a first cylinder fixed on both sides of the main frame. The output end of the first cylinder is fixedly provided with a clamping mechanism that cooperates with the drive component to clamp the transformer. The side ends of the drive component and the clamping mechanism are both fixedly provided with clamping blocks of the same shape, and the side ends of the clamping blocks on both sides are fixed in the grooves at both ends of the transformer.

[0007] A fixing ring is fixedly provided on the outer side of the clamping mechanism. A T-shaped groove is formed on the outer wall of the fixing ring. A slider is movably installed inside the groove. A limiting rod is fixedly provided at the lower end of the slider. An electric push rod that is inserted into the limiting rod is fixedly provided on the top of the main frame.

[0008] This invention allows for adjustment of the distance between the clamping blocks on both sides through the cooperation of the first cylinder and the clamping mechanism, facilitating the squeezing and clamping of both ends of the transformer. The upper and lower clamping operation of the clamping mechanism further fixes the position of the transformer winding installation. With the cooperation of the fixing ring and the electric push rod, the clamping mechanism can maintain a fixed position when adjusting the clamping distance. By inserting the clamping blocks into the grooves at both ends of the transformer, the installation position can be quickly fixed. At the same time, the upper and lower clamping method can further improve the stability of the transformer position during the winding process, reduce the phenomenon of transformer position displacement caused by vibration due to mechanical structure operation, and improve the winding accuracy.

[0009] Preferably, the top of the clamping block is fixedly provided with a flexible block that engages with the protrusion of the groove on the side end of the transformer, and the top of the flexible block is provided with an elastic groove facing downward.

[0010] Preferably, the clamping mechanism includes a second cylinder, the output end of the second cylinder is fixedly provided with a bearing, the outer wall of the bearing is fixedly provided with a trapezoidal extrusion block, both inclined surfaces of the extrusion block are fitted with movable blocks, both inclined surfaces of the extrusion block are fixedly provided with T-shaped sliders, the inclined surfaces of the two movable blocks are provided with grooves that engage with the sliders, both movable blocks are fixedly provided with adjusting plates on the side away from the second cylinder, and the outer sides of the extrusion block and the movable blocks are fitted with housings for limiting movement.

[0011] Preferably, a gear-shaped resistance disc is fixedly provided on the outer wall of the telescopic end of the second cylinder, and two resistance components with gap engagement between the adjacent meshing teeth of the resistance disc are fixedly provided on the side of the outer shell near the resistance disc.

[0012] Preferably, the resistance element includes a fixing block fixed to the side of the housing, the bottom of the fixing block is integrally formed with an elastic support strip, and the bottom of the support strip is integrally formed with a circular locking block.

[0013] Preferably, each of the two adjusting plates on opposite sides is fixed with a connecting sleeve that connects to the clamping block, and the connecting sleeve and the clamping block are connected by screws.

[0014] Preferably, the clamping blocks are fixedly provided on both opposite sides to the transformer, and the outer surface of the clamping blocks is provided with rubber pads.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model allows for adjustment of the distance between the clamping blocks on both sides through the cooperation of the first cylinder and the clamping mechanism, facilitating the squeezing and clamping of both ends of the transformer. The upper and lower clamping operation of the clamping mechanism can further fix the position of the transformer winding installation. With the cooperation of the fixing ring and the electric push rod, the clamping mechanism can maintain a fixed position when adjusting the clamping distance. By inserting the clamping blocks into the grooves at both ends of the transformer, the installation position can be quickly fixed. At the same time, the upper and lower clamping method can further improve the stability of the transformer position during the winding process, reduce the phenomenon of transformer position displacement caused by vibration due to mechanical structure operation, and improve the winding accuracy.

[0018] 2. This utility model also uses the flexible block and the elastic groove to deform when inserted into the groove on the side of the transformer due to the influence of the arc-shaped protrusions on both sides. The deformation effect and the connection with the protrusion can further improve the stability of the insertion. This can further strengthen the limitation of the transformer installation position and improve the stability of the transformer position during the winding process.

[0019] 3. This utility model also achieves a certain limiting effect through the cooperation of the resistance plate and the resistance component. In this way, after the transformer is removed, the clamping block on the side of the clamping mechanism can be kept aligned with the clamping block on the side of the drive component. This eliminates the need to adjust the position of the clamping block on the side of the clamping mechanism when clamping and installing the transformer, saving operation time and further improving the speed of fixing the transformer position.

[0029] like Figures 1 to 8 As shown, this utility model relates to a transformer winding device, including a winding device body 1 composed of a main frame 101, a wire feeding component 102, a tensioning component 103, a wire pushing component 104, and a winding component 105. The winding component 105 includes a driving component 2 and a first cylinder 3 fixed on both sides of the main frame 101. The output end of the first cylinder 3 is fixedly provided with a clamping mechanism 4 that cooperates with the driving component 2 to clamp the transformer. The driving component 2 and the side end of the clamping mechanism 4 are both fixed with clamping blocks 5 of the same shape, and the side ends of the clamping blocks 5 on both sides are fixed in the grooves at both ends of the transformer. The distance between the clamping mechanism 4 and the driving component 2 can be controlled by the operation of the first cylinder 3, so that the two ends of the transformer can be clamped. The design of the clamping blocks 5 can be inserted into the grooves at both ends of the transformer, so as to achieve a rapid positioning effect. At the same time, under the squeezing and clamping of the clamping mechanism 4, the installation position of the transformer can be further fixed, so that the position stability of the transformer can be improved during the winding process.

[0030] A fixing ring 6 is fixedly provided on the outer side of the clamping mechanism 4. A T-shaped movable groove 601 is opened on the outer wall of the fixing ring 6. A positioning block 602 is movably installed inside the movable groove 601. A limiting rod 603 is fixedly provided at the lower end of the positioning block 602. An electric push rod 7 that is inserted into the limiting rod 603 is fixedly provided at the top of the main frame 101. When the limiting rod 603 moves to the top position of the electric push rod 7, the electric push rod 7 can be inserted into the position of the limiting rod 603 by working upward, thereby achieving the docking effect. In this way, when the second cylinder 401 moves, the position of the outer shell 409 can be kept fixed and will not move synchronously. This can achieve the effect of clamping distance adjustment. The cooperation between the movable groove 601 and the positioning block 602 does not affect the rotation of one end of the clamping mechanism 4 with the drive component 2.

[0031] In an embodiment of this utility model, a flexible block 501 is fixedly provided on the top of the clamping block 5, which is combined with the protrusion of the groove on the side of the transformer. An elastic groove 502 is provided on the top of the flexible block 501. The flexible block 501 can deform when squeezed by the protrusions on both sides of the transformer groove. With the elastic groove 502, the two ends of the flexible block 501 can automatically tilt when squeezed, reducing the resistance to movement. In this way, when the flexible block 501 deforms and fits with the protrusion, the limiting effect of the insertion can be further improved, and the stability of the winding machine position can be strengthened.

[0032] In this embodiment of the present invention, the clamping mechanism 4 includes a second cylinder 401. A bearing 402 is fixedly mounted on the output end of the second cylinder 401. A trapezoidal pressing block 403 is fixedly mounted on the outer wall of the bearing 402. Movable blocks 404 are attached to both inclined surfaces of the pressing block 403. T-shaped sliders 405 are fixedly mounted on both inclined surfaces of the pressing block 403. Sliding grooves 406 that engage with the sliders 405 are opened on the inclined surfaces of the two movable blocks 404. Adjusting plates 407 are fixedly mounted on the side of each movable block 404 away from the second cylinder 401. External limiting devices are installed on the outer sides of the pressing block 403 and the movable blocks 404. Shell 409; When the position of the shell 409 is fixed, the operation of the second cylinder 401 can drive the extrusion block 403 to move, thereby driving the movable blocks 404 on both sides to move under the cooperation of the slider 405 and the slide groove 406. By changing the moving distance, the contact position between the extrusion block 403 and the movable block 404 is changed, thereby reducing the distance between the two movable blocks 404, achieving the effect of adjusting the distance between the two adjusting plates 407, and completing the operation of adjusting the clamping angle. The shell 409 can enclose the whole and play a limiting role, so that the movable block 404 has space to move smoothly.

[0033] In this embodiment of the invention, a gear-shaped resistance disc 8 is fixedly provided on the outer wall of the telescopic end of the second cylinder 401. Two resistance members 9 are fixedly provided on the side of the outer shell 409 near the resistance disc 8, which are engaged with the adjacent teeth of the resistance disc 8. The resistance member 9 includes a fixing block fixed to the side of the outer shell 409. The bottom of the fixing block is integrally formed with an elastic support strip, and the bottom of the support strip is integrally formed with a circular locking block. The combination of the resistance disc 8 and the resistance member 9 can limit the position of the outer shell 409, so that the clamping block 5 on one side of the outer shell 409 can remain in a fixed position when separated from the transformer, and is not prone to rotation. This can save the position adjustment step before the next clamping operation of the transformer, and improve the convenience of operation. The resistance member 9 can have a certain deflection effect through the cooperation of the fixing block and the support strip. This allows the circular locking block to shift when it is squeezed by the resistance disc 8, thereby locking into the teeth of the resistance disc 8 at different positions to achieve the limiting effect.

[0034] In the embodiments of this utility model, each of the two side adjustment plates 407 is fixedly provided with a connecting sleeve 408 connected to the clamping block 5 on the opposite side, and the connecting sleeve 408 and the clamping block 5 are connected by screws; the clamping block 5 is easy to disassemble and assemble by the cooperation, and it is convenient to replace clamping blocks 5 of different sizes.

[0035] In the embodiments of this utility model, the two opposite sides of the clamping block 5 are fixedly provided with limiting blocks 503 that fit against the two ends of the transformer, and the outer surface of the clamping block 5 is provided with rubber pads; the fitting of the limiting blocks 503 against the sides of the transformer can limit the distance between the side end of the clamping block 5 and the groove of the transformer.

[0036] In an embodiment of this utility model, the output end of the first cylinder 3 is fixedly provided with a mounting base 301 connected to the second cylinder 401. Two support plates 302 are fixedly provided at the bottom of the mounting base 301. A movable wheel 303 that fits against the top of the main frame 101 is rotatably installed between the lower ends of the two support plates 302. The stability of the clamping mechanism 4 can be improved by the arrangement of the support plates 302 and the movable wheel 303.

[0037] Working Principle: This embodiment provides a transformer winding device. In use, firstly, one end of the transformer is aligned with the clamping block 5 on the side of the drive component 2, allowing the clamping block 5 to be inserted into the grooves on both sides of the transformer side. This positions the transformer. Next, the first cylinder 3 is activated, pushing the clamping mechanism 4 towards the other end of the transformer. This allows the clamping block 5 on the side of the clamping mechanism 4 to be inserted into the groove at the other end of the transformer. The operation of the clamping mechanism 4 controls the upper and lower clamping blocks 5 to move closer together. The movement of the second cylinder 401 causes the pressing block 403 to pull the movable blocks 404 on both sides to move synchronously. The cooperation between the slider 405 and the slide groove 406 keeps the pressing block 403 and the movable blocks 404 in place. When block 404 is in contact, the clamping gap can be adjusted, which can further clamp the transformer and complete the operation of fixing the transformer position. Then the winding operation can be carried out. During the process of the transformer rotation controlled by the drive component 2, the bearing 402 can keep the position of the second cylinder 401 fixed and not affect the rotation operation. In this way, with the cooperation of the wire feeding component 102, the tensioning component 103 and the wire pushing component 104, the effect of uniform winding can be achieved. The resistance plate 8 and resistance component 9 structure set between the second cylinder 401 and the outer shell 409 can increase a certain rotation resistance. In this way, when the transformer is released, the position of the clamping block 5 at one end of the clamping mechanism 4 can be positioned so that the clamping blocks 5 on both sides are kept in the same position, which is convenient for the next use of clamping the transformer.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
