Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a thick wire diameter winding machine for winding current transformer coils. Background Technology

[0002] The transformer coil is the key component of an instrument transformer. It operates on the principle of electromagnetic induction and consists of a primary coil and a secondary coil. The primary coil is connected to a high-voltage or high-current circuit, while the secondary coil induces a corresponding low voltage or small current, thereby enabling functions such as measuring, monitoring, and protecting circuit parameters. It plays an extremely important role in power systems.

[0003] In the existing technology, there is a type of thick wire winding machine used for winding current transformer coils. When winding toroidal current transformer coils, three rotatable cylinders are usually used to hold the outside of the current transformer coil. The rotation of the cylinders causes the current transformer coil to rotate to carry out the winding operation. However, the position of the cylinders on most winding machines has a relatively narrow range of motion, making it difficult to match the fixing requirements of coils of different sizes.

[0004] To address the above problems, a coarse-diameter winding machine for winding current transformer coils is proposed.

[0005] To overcome the above shortcomings, this utility model provides a thick wire diameter winding machine for winding current transformer coils, aiming to improve the problem that the position of the cylinder on most existing winding machines has a relatively narrow range of movement, making it difficult to match the fixing requirements of coils of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a thick wire diameter winding machine for winding transformer coils, comprising a base, a winding device installed on the top of the base, a plurality of support columns fixedly connected to the top of the base, and an adjustment component provided on the top of the support columns;

[0007] The adjustment assembly includes a support base, the bottom of which is fixedly connected to the top of the support column. Multiple sliding grooves are formed inside the support base. A rotating shaft is rotatably connected inside the support base. A turntable is fixedly connected to the top of the rotating shaft. A frustum is fixedly connected to the top of the turntable. A sliding rod is fixedly connected inside each sliding groove. A slider is slidably connected to the outside of the sliding rod. A rotating rod is provided between the slider and the turntable. A fixed column is fixedly connected to the top of the slider. A stop column is rotatably connected inside the fixed column. A motor is fixedly connected to the inner wall of one of the fixed columns. A locking assembly is provided on the outside of the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] The locking assembly includes a worm gear and a worm. The inner wall of the worm gear is fixedly connected to the outside of the rotating shaft, and the outer side of the worm is rotatably connected to the inside of the base. A rotating rod is fixedly connected to the outer side of the worm.

[0010] As a further description of the above technical solution:

[0011] The motor output end is fixedly connected inside one of the abutments, and the top of the truncated cone is rotatably connected inside the support base.

[0012] As a further description of the above technical solution:

[0013] One end of the rotating rod is rotatably connected to the top edge of the turntable, and the other end of the rotating rod is rotatably connected to the bottom of the slider.

[0014] As a further description of the above technical solution:

[0015] The slider is slidably connected to the inside of the groove on its outer side.

[0016] As a further description of the above technical solution:

[0017] The outer side of the rotating rod is rotatably connected to the inside of the support base.

[0018] As a further description of the above technical solution:

[0019] A controller is provided on the outside of the winding device.

[0020] As a further description of the above technical solution:

[0021] The support base has a winding groove inside.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rotating rod drives the worm gear to rotate, which in turn drives the shaft to rotate, thereby driving the turntable to rotate. The rotating rod is also pulled to rotate, which in turn pulls the three sliders to slide relative to each other on the outside of the slider. This synchronously drives the fixed column and the abutment column to slide relative to each other, thus adapting to transformer coils of different sizes and expanding the applicability of the device.

[0024] 2. In this utility model, through the self-locking characteristic of worm gear transmission, the worm can prevent the worm wheel from rotating in the opposite direction, that is, prevent the shaft from rotating unexpectedly. This ensures that when the winding device is performing winding operation, the position of the abutment will not change due to the unexpected rotation of the shaft, thereby affecting the fixing effect of the transformer coil and the winding quality, and ensuring the stability and reliability of the winding process.

[0031] 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.

[0032] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a thick wire diameter winding machine for winding transformer coils, comprising a base 1, a winding device 2 installed on the top of the base 1, a plurality of support columns 3 fixedly connected to the top of the base 1, and an adjustment component provided on the top of the support columns 3.

[0033] The adjustment assembly includes a support base 4, the bottom of which is fixedly connected to the top of the support column 3. The support base 4 has multiple sliding grooves 6 inside, and a rotating shaft 9 is rotatably connected inside the support base 4. A turntable 11 is fixedly connected to the top of the rotating shaft 9, and a frustum 19 is fixedly connected to the top of the turntable 11. A sliding rod 13 is fixedly connected inside the sliding grooves 6, and a slider 12 is slidably connected to the outside of the sliding rod 13. A rotating rod 18 is provided between the slider 12 and the turntable 11. A fixed column 14 is fixedly connected to the top of the slider 12, and a stop column 16 is rotatably connected inside the fixed column 14. A motor 15 is fixedly connected to the inner wall of one of the fixed columns 14, and a locking assembly is provided on the outside of the rotating shaft 9.

[0034] Specifically, the base 1 is the basic support part of the entire equipment, used to support other components. The winding device 2 is the core component used for the actual winding of the current transformer coil. During operation, it winds the wire according to the set program and parameters to form a current transformer coil that meets the requirements. It includes structures such as a bobbin support, winding mold, wire laying mechanism, and counter. The multiple support columns 3 on the top of the base 1 connect the base 1 to the upper adjustment component, providing a stable support structure for the adjustment component. The support seat 4 in the adjustment component has its bottom fixed to the top of the support column 3. Multiple sliding grooves 6 inside provide a track for the subsequent sliding of the slider 12. The rotating shaft 9 inside the support seat 4 is rotatably connected. When it rotates, the turntable 11 fixedly connected to the top will rotate accordingly. The frustum 19 on the top of the turntable 11 can help maintain the stability of the structure and play a role in some operations. The sliding rod 13 in the slide groove 6 is slidably connected to the slider 12, allowing the slider 12 to slide smoothly on the sliding rod 13. The rotating rod 18 between the slider 12 and the turntable 11 is the key component for converting the rotation of the turntable 11 into the sliding of the slider 12. When the turntable 11 rotates, the rotating rod 18 pulls the slider 12 to slide outside the sliding rod 13. The fixed column 14 at the top of the slider 12 is rotatably connected to the abutment 16. The motor 15 on the inner wall of one of the fixed columns 14 can drive the abutment 16 to rotate. These abutments 16 are for contacting the transformer coil during the winding process. The locking assembly on the outside of the rotating shaft 9 is used to limit the rotation of the rotating shaft 9 through a specific mechanical structure when the position of the adjustment assembly needs to be fixed, so that the entire adjustment assembly remains stable and the winding effect is not affected by accidental rotation or displacement during the winding process.

[0035] Reference Figure 3 and Figure 4 The locking assembly includes a worm gear 10 and a worm 8. The inner wall of the worm gear 10 is fixedly connected to the outside of the rotating shaft 9, and the outer side of the worm 8 is rotatably connected to the inside of the base 1. A rotating rod 7 is fixedly connected to the outer side of the worm 8.

[0036] Specifically, the inner wall of the worm gear 10 is fixedly connected to the outer side of the rotating shaft 9 so that when the worm 8 rotates, the meshing transmission between the worm gear 10 and the worm 8 can enable the worm gear 10 to drive the rotating shaft 9 to rotate or lock. The outer side of the worm 8 is rotatably connected to the inside of the base 1 to provide a stable rotation support point for the worm 8, ensuring that it can run smoothly and maintain a suitable transmission position relationship during rotation. The rotating rod 7 is for the convenience of the operator to manually rotate it.

[0037] Reference 1- Figure 4 The output end of the motor 15 is fixedly connected inside one of the abutments 16. The top of the truncated cone 19 is rotatably connected inside the support base 4. The outer side of the slider 12 is slidably connected inside the slide groove 6. The outer side of the rotating rod 7 is rotatably connected inside the support base 4. A controller 17 is provided on the outer side of the winding device 2. A winding groove 5 is opened inside the support base 4.

[0038] Specifically, the output end of the motor 15 is fixedly connected inside one of the abutments 16 so that the rotation of the motor 15 drives the abutment 16 to rotate. During the winding of the transformer coil, the abutment 16 can be used to contact the coil and apply a certain force to it, assisting the winding action of the coil and making the coil more tightly and evenly wound. The top of the frustum 19 is rotatably connected inside the support base 4 to assist in supporting and stabilizing the turntable 11 and the components connected to it. When the rotating shaft 9 drives the turntable 11 to rotate, the frustum 19 can reduce the shaking of the turntable 11 and ensure that the movement of the entire adjustment assembly is more stable, thereby improving the accuracy and quality of the winding. The outer side of the slider 12 is slidably connected inside the slide groove 6 so that when the turntable 11 rotates, the slider 12 can slide smoothly along the slide groove 6 on the slide rod 13 through the linkage of the rotating rod 18, thereby driving the fixed column 14 and the abutment 16 to make relative position adjustments, so as to adapt to the fixing and winding requirements of transformer coils of different sizes and improve the versatility and flexibility of the winding machine. The rotating rod 7 is rotatably connected to the inside of the support base 4, providing a convenient operating component for the operator. The controller 17 is for the operator to set and control various parameters of the winding device 2, such as the winding speed, number of turns, and the start and end positions of the coil. The controller 17 can receive the operator's instructions and convert them into electrical signals to control the operation of the motor, wire laying mechanism and other components in the winding device 2, so that the winding process can be carried out accurately according to the predetermined process requirements. The winding groove 5 is used to accommodate and guide the current transformer coil and the wire connected to it during the winding process, so that the coil and the wire have a relatively regular path during the winding process.

[0039] Working principle: When it is necessary to fix current transformer coils of different sizes, rotating the rotating rod 7 drives the worm 8 to rotate. The meshing action of the worm 8 and the worm wheel 10 causes the worm wheel 10 to rotate, which in turn causes the rotating shaft 9 to rotate, thereby driving the turntable 11 to rotate and pulling the rotating rod 18 to rotate. This, in turn, pulls the three sliders 12 to slide relative to each other on the outside of the sliding rod 13, thereby synchronously driving the fixed column 14 and the abutment column 16 to slide relative to each other. This adapts to current transformer coils of different sizes, improving the applicability of the device. After the current transformer coil is fixed, the rotating rod 7 is stopped. At this time, the cooperation between the worm wheel 10 and the worm 8 locks the rotating shaft 9, thereby ensuring the stability of the positions of the fixed column 14 and the abutment column 16, providing a reliable fixed foundation for the subsequent winding of the current transformer coil. The drive 15 drives one of the abutment columns 16 to rotate, and the friction drives the current transformer coil and the other two abutment columns 16 to rotate synchronously, realizing the winding of the current transformer coil.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
