Description

Technical Field

[0001] The utility model relates to the field of winding frames, and more specifically, to a winding frame for transformer coils. Background Art

[0002] With the rapid development of modern power electronics technology and microelectronics technology, the technologies of variable frequency speed regulation devices with various powers have become increasingly mature. Therefore, the demand for transformers is increasing day by day. A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, etc. During the production process of transformers, a coil winding structure is required to wind enameled wire around transformer components to form a coil.

[0003] Currently, the winding structure for transformer coils mainly winds enameled wire around transformer components that are close to rectangular (the bending parts of the rectangle are smoothly processed). During the winding process of the enameled wire, there is no effective limiting structure to limit and press the coil against the transformer components in real time. In this way, gaps are easily formed during the winding of the coil, thus affecting the winding quality. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a winding frame for transformer coils. The technical problem to be solved by the utility model is: during the winding process of the enameled wire, there is no effective limiting structure to limit and press the coil against the transformer components in real time. In this way, gaps are easily formed during the winding of the coil, thus affecting the winding quality.

[0005] To achieve the above object, the utility model provides the following technical solution: A winding frame for transformer coils, including a base, a driving seat fixedly connected to the base, a transmission shaft rotatably connected to the driving seat, a transformer component arranged at one end of the transmission shaft, a winding motor arranged on the driving seat for driving the transmission shaft to rotate, a support frame one and a support frame two fixedly connected to the base, a linear module one arranged on the support frame one, a coil guiding component arranged at the sliding part of the linear module one, a horizontal and vertical linear driving unit arranged on the support frame two, and an elastic telescopic component arranged at the longitudinal output part of the horizontal and vertical linear driving unit;

[0006] The elastic telescopic component includes a lifting plate, a pair of T-shaped guide rods movably penetrating through the lifting plate, a support plate fixedly connected to the pair of T-shaped guide rods, and springs sleeved on each T-shaped guide rod. A torsion spring shaft is rotatably connected to the inner side of the support plate. Both ends of the torsion spring shaft are fixedly connected with roller frames. A pair of limiting rollers are rotatably connected to the pair of roller frames, and the pair of limiting rollers are in movable contact with the surface of the transformer component. A wire pressing motor for driving one of the limiting rollers to rotate is arranged on one of the roller frames.

[0007] In a preferred embodiment, one end of the transmission shaft is fixedly connected with a mounting plate, and the transformer component is fastened to the mounting plate by bolts.

[0008] In a preferred embodiment, the coil guiding assembly includes a rotating seat and a pair of wire rollers rotatably connected to the inner side of the rotating seat, and guiding grooves for coil limiting are formed on the wire rollers.

[0009] In a preferred embodiment, two pairs of mounting blocks are fixedly connected to the side surface of the rotating seat, and a cleaning brush is fixedly connected to each pair of mounting blocks.

[0010] In a preferred embodiment, the horizontal and vertical linear driving unit includes a linear module two, a moving frame fixedly connected to the sliding part of the linear module two, a fixing plate fixedly connected to one end of the moving frame, and a hydraulic device fixedly connected to the fixing plate.

[0011] In a preferred embodiment, the lifting plate is fixedly connected to the power output end of the hydraulic device.

[0012] Technical effects and advantages of the present utility model:

[0013] For a transformer coil winding rack of the present utility model, by pulling one end of the coil onto the transformer component to achieve fixation before winding, a pair of limiting rollers are elastically pressed against the transformer component, and due to the rotatability of the torsion spring shaft, the pair of limiting rollers can be kept in close contact with the rotating transformer component in real time, and at the same time, they act on pressing the coil being wound. The limiting roller located at the front side is driven to rotate counterclockwise by a wire pressing motor to increase the friction force in the reverse direction of coil conveying, so as to improve the winding tightness of the coil sent to the transformer component, and at the same time, another limiting roller is used to roll and press the coil in real time to ensure the fitting degree of coil winding, thereby achieving the limiting and pressing effects of coil winding.

[0014] For a transformer coil winding rack of the present utility model, by arranging a coil guiding assembly on the linear module one, it can reciprocally adjust the conveying position of the coil to realize reciprocating winding of the coil on the transformer component. At the same time, it can cooperate with the limiting rollers for moving limiting and pressing, and by evenly arranging the coils and limiting and pressing the winding of the coils in real time, the winding quality of the coils can be improved.

[0022] Refer to in combination Figures 1-4, the utility model provides a transformer coil winding rack, which includes a base 1. A driving seat 2 is fixedly connected to the base 1. A transmission shaft 3 is rotatably connected to the driving seat 2. One end of the transmission shaft 3 is provided with a transformer component 5. A winding motor 4 for driving the transmission shaft 3 to rotate is arranged on the driving seat 2. A support one 6 and a support two 7 are fixedly connected to the base 1. A linear module one 8 is arranged on the support one 6. A coil guiding component 9 is arranged at the sliding part of the linear module one 8. A horizontal and vertical linear driving unit is arranged on the support two 7. An elastic telescopic component 14 is arranged at the longitudinal output part of the horizontal and vertical linear driving unit.

[0023] One end of the transmission shaft 3 is fixedly connected with a mounting plate 31. The transformer component 5 is fastened to the mounting plate 31 by bolts. After the transformer component 5 is installed on the transmission shaft 3, the winding motor 4 can be used to drive the transformer component 5 to rotate for coil winding.

[0024] The coil guiding component 9 includes a rotating seat 91 and a pair of wire guiding rollers 92 rotatably connected to the inner side of the rotating seat 91. A guiding groove for limiting the enameled wire is arranged on the wire guiding roller 92. The rotating seat 91 can be fixedly connected to the sliding part of the linear module one 8. By passing the enameled wire through a pair of wire guiding rollers 92 and extending it to the transformer component 5, the arrangement of the guiding groove can enable the enameled wire to move in a limited way between the pair of wire guiding rollers 92. The linear module one 8 is used to drive the wire guiding roller 92 to move horizontally, so that the transmission position of the enameled wire can be changed to ensure sequential winding on the transformer component 5.

[0025] Two pairs of mounting blocks 19 are fixedly connected to the side surface of the rotating seat 91. A cleaning brush 20 is fixedly connected to each pair of mounting blocks 19. A pair of cleaning brushes 20 can be oppositely arranged outside the enameled wire passing through the wire guiding roller 92, so that the enameled wire can be cleaned of dust when passing through the cleaning brush 20.

[0026] The horizontal and vertical linear driving unit includes a linear module two 10, a moving frame 11 fixedly connected to the sliding part of the linear module two 10, a fixing plate 12 fixedly connected to one end of the moving frame 11, and a hydraulic device 13 fixedly connected to the fixing plate 12. The linear module two 10 and the hydraulic device 13 can endow the elastic telescopic component 14 and the structure connected to the elastic telescopic component 14 with linear movement in the horizontal and vertical directions.

[0027] The elastic telescopic component 14 includes a lifting plate 141, a pair of T-shaped guide rods 142 that movably penetrate the lifting plate 141, a support plate 143 fixedly connected to the pair of T-shaped guide rods 142, and springs 144 sleeved on each T-shaped guide rod 142. When the support plate 143 is stressed, the T-shaped guide rods 142 can penetrate upward through the lifting plate 141, and at the same time the springs 144 are compressed. A torsion spring shaft 15 is rotatably connected to the inner side of the support plate 143. Both ends of the torsion spring shaft 15 are fixedly connected with a pair of roller frames 16. A pair of limiting rollers 17 are rotatably connected to the pair of roller frames 16, and the pair of limiting rollers 17 are in active contact with the surface of the transformer component 5. A wire pressing motor 18 for driving one of the limiting rollers 17 to rotate is arranged on one of the roller frames 16.

[0028] The lifting plate 141 is fixedly connected to the power output end of the hydraulic device 13.

[0029] Specifically, the pair of limiting rollers 17 are pressed onto the transformer component 5 connected with the enameled wire through the hydraulic device 13. When the transformer component 5 rotates, the enameled wire can be wound on the transformer component 5 at this time. According to the design of the special structure of the transformer component 5, that is, a rectangular structure with the bending part being smoothly processed, the torsion spring shaft 15 drives the pair of limiting rollers 17 to rotate with tension. Under the cooperation of the T-shaped guide rods 142 and the lifting plate 141 movably penetrating, and the compression of the springs 144 on the T-shaped guide rods 142, the pair of limiting rollers 17 can rotate in a fitting manner along the surface path close to the transformer component 5. By starting the wire pressing motor 18 to drive one of the limiting rollers 17 to rotate, its rotation direction can be opposite to the conveying direction of the enameled wire to increase the friction force in the reverse direction of the enameled wire conveying. In this way, the tightening of the enameled wire fed onto the transformer component 5 can be improved. At the same time, the other limiting roller 17 is used to roll and press the enameled wire in real time to ensure the fitting degree of the enameled wire winding, so as to achieve the limiting and pressing effects of the enameled wire winding. During this process, the linear module two 10 can adaptively drive the pair of limiting rollers 17 to move horizontally to meet the requirements of winding coils of different lengths of the transformer component 5.
