Description

Technical Field

[0001] This utility model belongs to the field of transformer processing technology, specifically relating to a tooling fixture for winding copper foil in transformers. Background Technology

[0002] A transformer consists of an iron core or magnetic core and coils. The coils have two or more windings; the winding connected to the power source is called the primary winding, and the remaining windings are called secondary windings. Transformers perform functions such as voltage reduction, voltage increase, signal coupling, energy transfer, impedance transformation, and isolation. In practical applications, there is a type of transformer that uses copper foil (copper sheet) instead of copper wire, which achieves low leakage inductance and high coupling efficiency.

[0003] Currently, most existing transformer copper sheet winding processes lack the function of clamping the ends of the copper sheet. They only achieve winding by creating grooves on the winding column and placing the ends of the copper sheet in the grooves. This easily leads to the copper sheet ends detaching from the grooves at the beginning of the winding process, resulting in winding failure and greatly reducing the efficiency of copper sheet winding. To address this, we propose a transformer copper sheet winding fixture. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling fixture for winding copper sheet in transformers, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer copper foil winding fixture, comprising a base, a turntable, a fixed clamping plate, and a movable clamping plate. The turntable is movably connected to the top of the base. A fixed clamping plate is fixedly welded to one side of the top center of the turntable. A drive groove is formed on the other side of the top center of the turntable. One end of the drive groove extends to the bottom of the fixed clamping plate. A clamping motor is fixedly installed at the end of the drive groove away from the fixed clamping plate. A screw is provided at the output shaft end of the clamping motor. The other end of the screw is movably connected to the inner wall of one end of the drive groove through a bearing. A slider is slidably arranged inside the drive groove. A movable clamping plate is fixedly welded to the top of the slider. Both the movable clamping plate and the fixed clamping plate are semi-circular main structures. A threaded sleeve is embedded in the inner side of the slider. The threaded sleeve is sleeved on the outer circumference of the screw and helically connected to it.

[0006] Preferably, an electric lifting frame is fixedly installed at both ends of the top of the base, and a positioning end sleeve is provided at the center of the inner top wall of the electric lifting frame, with a slot provided at the bottom of the positioning end sleeve.

[0007] Preferably, the inner walls on both sides of the drive groove are provided with limiting grooves, and the outer sides of the slider are provided with limiting blocks, which extend into the interior of the limiting groove and are slidably connected to its inner wall.

[0008] Preferably, a drive motor is fixedly installed at the center of the base, and the output shaft of the drive motor passes through the housing of the base and is fixedly connected to the center of the bottom of the turntable.

[0009] Preferably, both the turntable and the positioning end sleeve are provided with bushings at their ends. The turntable is movably connected to the base through the bushings, and the positioning end sleeve is movably connected to the inner top wall of the electric lifting frame through the bushings.

[0010] Preferably, the bottom of the positioning end sleeve is provided with a flared opening, which extends to the bottom edge of the positioning end sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a fixed clamping plate and a movable clamping plate on the top of the turntable, the clamping motor in the drive slot drives the screw to rotate, which in turn drives the threaded sleeve and the slider to move, thereby driving the movable clamping plate to move closer to the fixed clamping plate and clamp and fix the end of the copper sheet, ensuring its stability and preventing the end of the copper sheet from detaching at the beginning of winding.

[0013] 2. By setting up an electric lifting frame and installing a positioning end sleeve on its inner top wall, the stability of the copper sheet end clamping after the fixed clamping plate and the movable clamping plate are combined is ensured, and the top of the movable clamping plate is prevented from loosening, which would lead to unstable clamping. In conjunction with the electric lifting frame, the positioning end sleeve is raised and lowered, preventing the finished copper sheet winding from being removed. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution for a transformer copper foil winding fixture: it includes a base 1, a turntable 3, a fixed clamping plate 4, and a movable clamping plate 9. The turntable 3 is movably connected to the top of the base 1. The fixed clamping plate 4 is fixedly welded to one side of the top center position of the turntable 3. A drive groove 5 is opened on the other side of the top center position of the turntable 3. One end of the drive groove 5 extends to the bottom of the fixed clamping plate 4. A clamping motor 7 is fixedly installed at the end of the drive groove 5 away from the fixed clamping plate 4. A screw 8 is provided at the output shaft end of the clamping motor 7. The other end of the screw 8 is movably connected to the inner wall of one end of the drive groove 5 through a bearing. A slider 10 is slidably arranged inside the drive groove 5. The movable clamping plate 9 is fixedly welded to the top of the slider 10. Both the movable clamping plate 9 and the fixed clamping plate 4 are semi-circular main structures. A threaded sleeve 12 is inlaid on the inner side of the slider 10. The threaded sleeve 12 is sleeved on the outer circumference of the screw 8 and is helically connected to it.

[0020] Specifically, an electric lifting frame 13 is fixedly installed at both ends of the top of the base 1. A positioning end sleeve 14 is provided at the center of the inner top wall of the electric lifting frame 13, and a slot 16 is provided at the bottom of the positioning end sleeve 14.

[0021] Specifically, the inner walls of both sides of the drive groove 5 are provided with limiting grooves 6, and the outer sides of the slider 10 are provided with limiting blocks 11. The limiting blocks 11 extend into the interior of the limiting grooves 6 and slide in connection with their inner walls.

[0022] Specifically, a drive motor 2 is fixedly installed at the center of the interior of the base 1, and the output shaft of the drive motor 2 passes through the housing of the base 1 and is fixedly connected to the center of the bottom of the turntable 3.

[0023] Specifically, both the turntable 3 and the positioning end sleeve 14 are provided with bushings 15 at their ends. The turntable 3 is movably connected to the base 1 through the bushings 15, and the positioning end sleeve 14 is movably connected to the inner top wall of the electric lifting frame 13 through the bushings 15.

[0024] Specifically, the bottom of the positioning end sleeve 14 is provided with a flared opening 17, which extends to the bottom edge of the positioning end sleeve 14.

[0025] In this embodiment, during use, the end of the copper sheet is inserted between the fixed clamping plate 4 and the movable clamping plate 9. The clamping motor 7 drives the screw 8 to rotate, which in turn moves the threaded sleeve 12, thereby driving the slider 10. The slider 10 drives the movable clamping plate 9 to move closer to the fixed clamping plate 4, thus clamping and fixing the end of the copper sheet. Then, the electric lifting frame 13 drives the positioning end sleeve 14 to move down, so that the cylindrical shape formed by the fixed clamping plate 4 and the movable clamping plate 9 is inserted into the slot 16 at the bottom of the positioning end sleeve 14, thereby limiting the position of the movable clamping plate 9 and preventing unstable clamping at the top of the movable clamping plate 9, thus improving the clamping stability of the movable clamping plate 9. Finally, the drive motor 2 drives the turntable 3 to rotate, which drives the fixed clamping plate 4 and the movable clamping plate 9 to rotate, thereby winding the copper sheet. After winding is completed, the electric lifting frame 13 drives the positioning end sleeve 14 to rise, so that the cylindrical shape formed by the fixed clamping plate 4 and the movable clamping plate 9 is disengaged from the slot 16. Finally, the copper sheet winding can be removed.
