The winding quality of the coil insulation material directly affects the performance and service life of the transformer. Generally, after the coil drum is fixed, the winding action is completed by driving a motor to rotate the coil drum.

[0003] Existing coil drums come in various sizes, and winding devices cannot quickly fix coil drums of different sizes, meaning they are poorly adaptable to different specifications of coil drums and cannot meet diverse production needs. Utility Model Content

Therefore, the proposed winding device for transformer coil insulation material is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A winding device for transformer coil insulation material includes a mounting base. A drive motor is fixedly mounted on the surface of the mounting base. The output shaft of the drive motor passes through the mounting base and is fixedly mounted on a sleeve post. One end of the sleeve post has a mounting groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-6 A winding device for transformer coil insulation material includes a mounting base 1. A drive motor 2 is fixedly mounted on the surface of the mounting base 1. The output shaft of the drive motor 2 passes through the mounting base 1 and is fixedly mounted on a sleeve post 3. One end of the sleeve post 3 has an installation groove. The surface of the sleeve post 3 has multiple through holes in a circular shape. Multiple mounting blocks 4 with right-angled trapezoidal longitudinal sections are arranged in a circular shape in the installation groove. Each mounting block 4 corresponds to the position of each through hole. A backing plate 5 is fixedly mounted on the surface of the mounting block 4. A strip-shaped opening 6 is opened on the surface of the mounting block 4. Multiple U-shaped rods 7 are fixedly mounted in a circular shape on the groove wall of the installation groove. The multiple U-shaped rods 7 are slidably arranged in the multiple strip-shaped openings 6. The U-shaped rods 7 are connected to the mounting blocks 4 through elastic components. The elastic components include two telescopic springs 12. The two ends of the telescopic springs 12 are fixedly connected to the top wall of the strip-shaped opening 6 and the surface of the U-shaped rods 7, respectively.

[0024] A threaded rod 8 is horizontally rotatably mounted in the mounting slot. A slider 9 is threaded onto the threaded rod 8. Multiple abutments 10 are fixedly mounted on the surface of the slider 9 in a circumferential shape. An inclined groove 11 is opened on the inclined surface of the mounting block 4. The multiple abutments 10 are slidably arranged in the multiple inclined grooves 11 respectively. The threaded rod 8 is controlled to rotate by a drive assembly. The drive assembly includes a servo motor 13 fixedly mounted on one end of the sleeve post 3 through a connecting component. The connecting component includes a mounting ring 14 fixedly mounted on the servo motor 13 and two connecting rods 15 symmetrically fixedly mounted on the surface of the mounting ring 14. One end of the connecting rod 15 is fixedly connected to the surface of the sleeve post 3. The output shaft of the servo motor 13 is fixedly connected to the threaded rod 8. A baffle 17 is fixedly mounted on the sleeve post 3.

[0025] First, the coil tube to be fixed is placed on the sleeve post 3, and one end of the coil tube abuts against the surface of the baffle 17. Then, the servo motor 13 is started to control the rotation of the threaded rod 8. The slider 9 threaded onto the threaded rod 8 will move along with multiple abutments 10. When the multiple abutments 10 move toward the mounting base 1, under the pressure of the inclined plane, the multiple mounting blocks 4 and multiple abutments 5 will move away from each other, and the multiple telescopic springs 12 will be stretched. When the multiple abutments 10 move away from the mounting base 1, the multiple mounting blocks 4 and multiple abutments 5 will move closer to each other under the elastic potential energy of the multiple telescopic springs 12 until the surfaces of the multiple abutments 5 are tightly abutted against the inner wall of the coil tube, thus completing the fixing of the coil tube. At this time, the drive motor 2 is started, and the output shaft of the drive motor 2 will rotate along with the sleeve post 3 and the coil tube.

[0026] An anti-slip pad is adhered to the surface of the abutment plate 5 away from the mounting block 4. The anti-slip pad is made of rubber, which has good elasticity and adhesion, thereby increasing the friction between the abutment plate 5 and the coil drum contact surface.

[0027] The top and both sides of the abutment block 10 are provided with spherical grooves, and rolling balls 16 are embedded in the spherical grooves.

[0028] The ball 16 can reduce the friction between the contact surface of the abutment 10 and the inclined groove 11, and avoid the abutment 10 from getting stuck due to excessive friction between the contact surface of the abutment 10 and the inclined groove 11.

[0029] In this invention, the coil tube to be fixed is first placed on the sleeve post 3, and one end of the coil tube abuts against the surface of the baffle 17. At this time, the threaded rod 8 is rotated by the servo motor 13, and the slider 9 threaded onto the threaded rod 8 will move along with multiple abutment blocks 10. When the multiple abutment blocks 10 move toward the mounting base 1, under the action of the inclined surface, the multiple mounting blocks 4 and multiple abutment plates 5 will move away from each other, and the elastic components will be stretched. When the multiple abutment blocks 10 move away from the mounting base 1, the multiple mounting blocks 4 and multiple abutment plates 5 will move closer to each other under the elastic potential energy of multiple sets of elastic components until the surfaces of multiple abutment plates 5 are tightly abutted against the inner wall of the coil tube, thus completing the fixing of the coil tube. It can quickly fix coil tubes of different specifications that are sleeved on the sleeve post 3, and has strong adaptability.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
