Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coil winding, in particular to a synchronous rotating mechanism for tightening transformer coils. BACKGROUND

[0002] The main functions of a transformer include the following points:

[0003] 1. Voltage transformation: A transformer can increase or decrease voltage to meet different power needs. For example, in long-distance power transmission, the voltage needs to be increased to reduce line losses; while at the user end, the voltage needs to be reduced to a level suitable for household appliances.

[0004] 2. Current transformation: A transformer can change the size of the current without changing the power. For example, a welding machine uses a transformer to convert high voltage to low voltage while increasing the current to meet the welding requirements.

[0005] 3. Impedance transformation: In electronic circuits, transformers can be used for impedance matching to ensure the efficiency and quality of signal transmission. For example, in an audio amplifier, a transformer is used to match the impedance between the amplifier and the loudspeaker.

[0006] 4. Isolation: A transformer can isolate the primary and secondary circuits to improve electrical safety. For example, an isolation transformer used in medical equipment can prevent patients from being harmed by equipment leakage.

[0007] 5. Voltage stabilization: Some specially designed transformers, such as magnetic saturation transformers, can stabilize the output voltage within a certain range, providing a more stable power supply.

[0008] In summary, a transformer, through the principle of electromagnetic induction, realizes the transformation of voltage, current and impedance, as well as the isolation of circuits and the stabilization of voltage, and is an indispensable component in power systems and electronic devices. A transformer is composed of a core (or magnetic core) and a coil, and the coil has two or more windings, of which the winding connected to the power source is called the primary winding, and the remaining windings are called the secondary winding. It can transform AC voltage, current and impedance. A simple core transformer consists of a core made of soft magnetic material and two coils with different numbers of turns wrapped around the core. The core's function is to enhance the magnetic coupling between the two coils. To reduce eddy current and hysteresis loss in the core, the core is made of laminated silicon steel sheets; the two coils are not electrically connected, and the coils are made of insulated copper wire (or aluminum wire).

[0043] In addition, the driving assembly 401 is arranged between the two clamping members 101 and 102, the driving assembly 401 is used for providing power for the tightening clamping opening 105, the driving assembly 401 adopts a spring, an elastic belt, an electric telescopic rod or an air cylinder, or other devices capable of driving the two clamping members 101 and 102 to move towards or away from each other.

[0044] According to the driving direction of the driving assembly 401, the driving movement direction of the driving assembly 401 will change, the first driving mode is as follows, Figure 8As shown, when the driving assembly 401 expands the driving arms 106, 107 to the sides, Figure 8 The arrow in the figure indicates the expansion direction of the driving assembly 401, the opening of the clamping port 105 is reduced, the plurality of tightening shafts 201 clamps the outside of the coil 301 and exerts pressure on the outside of the coil 301, when the driving assembly 401 makes the driving arms 106, 107 close to each other, the opening of the clamping port 105 is enlarged;

[0046] In addition, the driving arm 106 is provided with a limiting assembly 501, which limits the angle of expansion of the two driving arms 106, 107. The specific implementation of the limiting assembly is that the limiting assembly 501 has a connecting rod 502 and a limiting cap 503 arranged at one end of the connecting rod 502, the other end of the connecting rod 502 is installed on one of the driving arms 106 or 107, the other driving arm 107 or 106 is provided with a through slot 504 for the connecting rod 502 to pass through, and the limiting cap 503 cannot pass through the through slot 504.

In addition, the limiting assembly 501 can also use other assemblies that can limit the angle of expansion of the two driving arms 106 and 107.

[0047] It also includes a driving transmission member 601 installed on the clamping members 101, 102 for inputting power, and the driving transmission member 601 and the tightening shaft 201 are connected through a transmission assembly 701.

[0048] Further specific embodiment of the transmission assembly, the transmission assembly group 701 includes the driving pin 602 installed on the driving gear 702, the driven gear 703 installed on the tightening shaft 201, and a plurality of transmission gears 704 for transmitting power to drive a plurality of winding shafts 201 to rotate. The driving pin 602 is rotated by the 4-pin shaft 602 to transmit power to the 6 driving gear 702, and the power on the driving gear 702 is transmitted to the driven gear 703 through the transmission gear 704, and then drives the corresponding plurality of tightening shafts 201 to rotate to tighten the coil 301. Bearing 9 fixes the pin 602 and the driving gear 702, and pin 10 passes through the driving gear 702 and the pin 602, which is used to limit the up and down movement of the driving gear 702 and transmit force. The driving gear 702 drives the transmission gear 704 to rotate, and the transmission gear 704 is installed in the same way as the driving gear 702, and transmits force to the driven gear 703 and the tightening shaft 201 through the transmission gear 704. In turn, the transmission gear 704 transmits force to the tightening shaft 201 that needs to be used.

[0049] When the driving two clamping pieces 101, 102 move relative to each other to open and close the clamping opening 105, the driven gear 703 makes planetary motion around the transmission gear 704 and transmission, forming an opening action.

[0050] The transmission assembly 701 can use gears for transmission, or use the cooperation of chains and sprockets for transmission power, or use the cooperation of belts and pulleys for transmission power, as long as the transmission power device can be realized.

[0051] The driving transmission member 601 includes a pin 602 rotatably connected to the clamping piece 101 or 102, the pin 602 is provided with a helical gear 603, and a helical gear 604 engaged with the helical gear 603, the motor and the helical gear 604 are connected, and the helical gear 604 is connected to the helical gear 603 to transmit power; the pin 602 can also be directly connected to the rotating output end of the motor, or can be connected to the pin 602 after the motor is reduced by the speed reducer.

[0052] Each tightening shaft 201 is connected to the clamping part 103, 104 through the quick release pin 11, and if the maintenance needs to replace the tightening shaft 201, the quick release pin 11 can be disassembled to replace the damaged tightening shaft 201, which is more convenient and fast during replacement.

[0054] In summary, the synchronous rotating mechanism for tightening the transformer coil is used to tighten the coil 301 after the winding and rubber coating of the coil 301 are completed. The two clamping pieces 101 and 102 are driven to move by the driving assembly 401. The driving assembly 401 is used to provide power for the tightening clamping opening 105. The two clamping pieces 101 and 102 are driven to move to open the clamping opening 105. The coil 301 is placed between the plurality of tightening shafts 201. The two clamping pieces 101 and 102 are driven to move to close the clamping opening 105. The plurality of tightening shafts 201 are used to clamp the outer part of the coil 301 and press the outer part of the coil 301. After the plurality of tightening shafts 201 clamp the coil 301, the tightening shafts 201 are driven to rotate by the motor. The coil 301 is driven to rotate by the rotation of the tightening shafts 201. Since the plurality of tightening shafts 201 press the outer part of the coil 301 at the same time and with the same pressure, the coil 301 is more uniformly tightened by the conduction and tightening of the equal division force of the plurality of tightening shafts 201. Therefore, the tightening effect of the coil 301 is improved.

[0055] After the coil 301 is tightened and processed, the two clamping pieces 101 and 102 are driven to move by the driving assembly 401. The two clamping pieces 101 and 102 are driven to move to open the clamping opening 105. Then, the coil 301 that is tightened and processed is removed.
