Description

Technical Field

[0001] This utility model relates to the field of toroidal transformer technology, and in particular to an automatically adjustable toroidal transformer winding positioning device. Background Technology

[0002] Toroidal transformers are a major type of electronic transformer, widely used in household appliances and other technically demanding electronic equipment. Their primary applications are as power transformers and isolation transformers. Abroad, toroidal transformers have a complete series available and are widely used in computers, medical equipment, telecommunications, instrumentation, and lighting. In the past decade, my country has developed toroidal transformer production from scratch, and now boasts a considerable production scale, meeting domestic demand and exporting a large quantity.

[0003] A toroidal transformer can step up or step down voltage by winding primary and secondary coils with different numbers of turns to meet the voltage requirements of different devices.

[0004] The winding of a toroidal transformer needs to be completed using a winder. Before winding, the toroidal transformer must be positioned. In the current technology, the positioning of the toroidal transformer needs to be done manually, which is not only time-consuming, but also requires a person to hold the toroidal transformer manually during the adjustment process. This may cause the toroidal transformer to fall and be damaged due to the confusion caused by the person's hands and feet. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An automatically adjustable toroidal transformer winding positioning device includes a base, on which two parallel rails are fixedly connected. An automatic drive device is included between the two rails. The automatic drive device includes a lead screw seat located between the two rails. A connecting plate is provided at each of the left and right ends of the lead screw seat. The two ends of the lead screw are respectively connected to the corresponding connecting plates via bearings. The lead screw is threadedly connected to a movable threaded seat. A movable plate is fixedly connected to the top of the movable threaded seat. A movable slider is provided on each of the front and rear sides of the bottom of the movable plate. Each movable slider is slidably connected to the corresponding rail.

[0007] The movable plate is provided with a symmetrical first positioning rod and a second positioning rod on its front and rear sides respectively. A connecting seat is provided at one end of the track near the first positioning rod and the second positioning rod. The connecting seat is provided with an integral connecting ear on each of its front and rear sides. The connecting ear is fixedly connected to the track. A third positioning rod is provided at the top of the connecting seat. The first positioning rod, the second positioning rod and the third positioning rod are arranged in an isosceles triangle. The third positioning rod is placed at the apex of the isosceles triangle.

[0008] The top of the first positioning rod, the second positioning rod, and the third positioning rod are all provided with an "I"-shaped rotating wheel, and the toroidal transformer is stuck between the three rotating wheels.

[0009] Furthermore, the base is a rectangular plate.

[0010] Furthermore, the third positioning rod is connected to the output end of a geared motor, and the geared motor is fixedly connected to the connecting seat.

[0011] Furthermore, one end of the lead screw is connected to a motor.

[0012] Furthermore, all the aforementioned wheels are at the same height.

[0013] Compared with existing technologies, the beneficial effects of this utility model are: the automatically adjusting toroidal transformer winding positioning device of this utility model can realize the automatic adjustment and positioning of the toroidal transformer. This reduces manual operation, shortens the toroidal transformer winding processing time, and thus improves overall production efficiency. Automatic adjustment also reduces production downtime.

[0018] Figure 3 This is a top view of the structure of this utility model. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0020] An automatically adjustable toroidal transformer winding positioning device includes a base 1, on which two parallel tracks 2 are fixedly connected. An automatic drive device 3 is included between the two tracks 2. The automatic drive device 3 includes a lead screw seat 31, which is located between the two tracks 2. A connecting plate 32 is provided at each of the left and right ends of the lead screw seat 31. The two ends of a lead screw 33 are respectively connected to the connecting plate 32 on the corresponding side through bearings 341. A movable threaded seat 34 is threadedly connected to the lead screw 33. A movable plate 35 is fixedly connected to the top of the movable threaded seat 34. A movable slider 36 is provided on each of the front and rear sides of the bottom of the movable plate 35. Each movable slider 36 is slidably connected to the track 2 on the corresponding side.

[0021] The movable plate 35 is provided with a symmetrical first positioning rod 4 and a second positioning rod 5 on its front and rear sides respectively. A connecting seat 6 is provided at one end of the track 2 near the first positioning rod 4 and the second positioning rod 5. The connecting seat 6 is provided with an integral connecting ear 61 on its front and rear sides. The connecting ear 61 is fixedly connected to the track 2. A third positioning rod 7 is provided at the top of the connecting seat 6. The first positioning rod 4, the second positioning rod 5 and the third positioning rod 7 are arranged in an isosceles triangle. The third positioning rod 7 is placed at the apex of the isosceles triangle.

[0022] The top of the first positioning rod 4, the second positioning rod 5, and the third positioning rod 7 are all provided with an "I"-shaped rotating wheel 8, and the ring transformer 9 is stuck between the three rotating wheels 8.

[0023] Furthermore, the base 1 is a rectangular plate.

[0024] Furthermore, the third positioning rod 7 is connected to the output end of a reduction motor 10, and the reduction motor 10 is fixedly connected to the connecting seat 6.

[0025] Furthermore, one end of the lead screw 33 is connected to the motor 11.

[0026] Furthermore, all of the aforementioned wheels 8 are at the same height.

[0027] In use, the toroidal transformer winding positioning device first places the toroidal transformer between the three rotating wheels 8. Then, the motor 11 is activated, causing the lead screw 33 to rotate. The movable threaded seat 34, which is threaded to the lead screw 33, moves linearly towards the third positioning rod 7. As the movable threaded seat 34 moves, the movable plate 35 on it moves accordingly. The movable slider 36 at the bottom of the movable plate 35 slides along the track 2. The movable plate 35 drives the first positioning rod 4 and the second positioning rod 5 on it to gradually move towards the third positioning rod 7 until the toroidal transformer 9 is locked between the three rotating wheels 8. The motor then stops. During winding, the toroidal transformer 9 is driven by the reduction motor 10 to rotate the third positioning rod 7. The rotating wheel 8 on the third positioning rod 7 rotates, causing the toroidal transformer 9 to rotate between the three rotating wheels 8, so that the coil can be wound evenly on the toroidal transformer 9. When winding is finished, the reduction motor 10 stops rotating, and the motor 11 drives the lead screw 33 to reverse, causing the first positioning rod 4 and the second positioning rod 5 to gradually move away from the third positioning rod 7 until the toroidal transformer 9 is released and can be removed. The motor 11 then stops.

[0028] The specific implementation of this utility model has been described in detail above, but it is only an example. This utility model is not limited to the specific implementation cases described above, and equivalent modifications to this utility model are also within the protection scope of this utility model.
