[0019] To make the above-mentioned objectives, features and advantages of this utility model more easily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figure 1 - Figure 4 This is the first embodiment of the present invention. This embodiment provides a winding bracket for a wound iron core transformer, including: a transverse base 1, a longitudinal base 2, a column 3, a panel 4, and a bearing lower seat 5; the longitudinal base 2 is fixedly installed on the outer wall of the transverse base 1, the column 3 is fixedly installed on the top of the transverse base 1, the panel 4 is fixedly installed on the top of the column 3, and the bearing lower seat 5 is embedded in the top of the panel 4, and also includes: Adjustment mechanism 6 and calibration mechanism 7; adjustment mechanism 6 is located on one side of the top of bearing lower seat 5, and calibration mechanism 7 is located on the other side of the top of bearing lower seat 5.

[0023] Specifically, the adjustment mechanism 6 includes: a mounting base 601, a bellows 602, a support cylinder 603, a support rod 604, a piston plate 605, a partition 606, a through hole 607, an electromagnetic coil 608, a guide cylinder 609, an upper bearing seat 610, a connecting bearing 611, a return spring 612, and a sealing plate 613. The mounting base 601 is fixedly installed on the top of the lower bearing seat 5. The bellows 602 is fixedly installed on the top of the mounting base 601, and the support cylinder 603 is inserted into the inside of the bellows 602.

[0024] Furthermore, the bellows 602 can cover and protect the adjustment mechanism 6, preventing external dust from being adsorbed and entering the interior of the support cylinder 603 and causing an impact, and can adaptively extend and retract according to the adjustment of the adjustment mechanism 6.

[0025] Specifically, a support rod 604 extends from the bottom end of the support cylinder 603, and a piston plate 605 is fixedly installed at the top end of the support rod 604.

[0026] Furthermore, by inserting the support rod 604 into the support cylinder 603 to form a telescopic structure, and cooperating with the piston plate 605 to form a piston structure, the overall stability of the winding can be improved.

[0027] Specifically, a partition 606 is fixedly installed inside the support cylinder 603, and a through hole 607 is provided on the inner wall of the partition 606.

[0028] Furthermore, the through-hole 607 opened through the partition 606 can generate pressure when shaking occurs, which can squeeze the silicone oil filler and allow it to flow through the through-hole 607 to achieve a buffering effect, making it more suitable for situations with high requirements for stability and environmental adaptability.

[0029] Specifically, an electromagnetic coil 608 is embedded in the outer wall of the support cylinder 603, and a guide cylinder 609 is sleeved around the electromagnetic coil 608.

[0030] Furthermore, the silicone oil filler is filled with carbonyl iron powder, which, in conjunction with the electromagnetic coil 608, can adjust the damping force and achieve real-time buffering of load fluctuations.

[0031] Specifically, a bearing seat 610 is fixedly installed at the top of the support cylinder 603, and a connecting bearing 611 is embedded at the top of the bearing seat 610.

[0032] Furthermore, the upper bearing seat 610 and the connecting bearing 611 are connected to the connecting shaft of the iron core winding machine to achieve the winding effect.

[0033] Specifically, a return spring 612 is embedded in the top of the support cylinder 603, and a sealing plate 613 is fixedly installed at the bottom of the return spring 612.

[0034] Furthermore, when there is no shaking or vibration or in a non-winding state, the silicone oil filler can be allowed to flow back to the bottom of the partition plate 606 by the elastic push of the sealing plate 613 by the reset spring 612.

[0035] In use, firstly, the horizontal base 1 and the vertical base 2 are spliced ​​together to form an integral base, which is then fixed to the ground with bolts. Subsequently, the lower bearing seat 5 is stably installed by the coordinated cooperation of the channel steel column 3 and the panel 4. On this basis, the connecting bearing 611 embedded in the upper bearing seat 610 can be directly connected to the connecting shaft of the winding machine. The entire structure is assembled using conventional and readily available materials, which not only greatly improves the ease of assembly but also effectively reduces the overall manufacturing cost. To cope with vibration and load fluctuation problems during operation, a piston assembly is formed between the lower bearing seat 5 and the upper bearing seat 610 by fixing the support cylinder 603 and the support rod 604 with the mounting base 601. The support cylinder 603 is filled with a mixed filler of silicone oil and carbonyl iron powder under the partition 606. When the equipment shakes or vibrates, the mixed filler will be pushed by the piston plate 605 and pass through the through hole 607 through the partition 606. The flow of fluids allows for rapid buffering and vibration reduction. Simultaneously, a pressure sensor connected to the outer ring of the bearing 611 can collect dynamic load data during the core winding process in real time and transmit it to the control terminal. The controller of the entire device outputs an induced current signal based on load changes, altering the magnetic field strength of the electromagnetic coil 608. Utilizing the magnetic field's effect on the mixed filler of silicone oil and carbonyl iron powder, the damping force can be adjusted in real time to precisely match load fluctuations for buffering. This solves the problems of excessively large size and inconvenience of traditional supports, and overcomes the structural vibration problem caused by sudden load changes. Furthermore, it can adapt to the winding requirements of cores of different weights without replacing support components, significantly improving overall versatility. In the non-winding state, the return spring 612 pushes the mixed filler back to its initial position through the through hole 607, achieving mechanism reset. In addition, the device is equipped with a PTFE guide cylinder 609 and an external bellows 602, which respectively serve guiding, protective, and sealing functions, ensuring that the support cylinder 603 only extends and retracts axially, avoiding radial offset that affects load-bearing accuracy and ensuring stable equipment operation.

[0036] In summary, the winding machine support device is assembled by splicing and fixing the transverse base 1 and the longitudinal base 2, installing the lower bearing seat 5 and the upper bearing seat 610 which is embedded in the connecting bearing 611 of the swivel bearing, with the channel steel column 3 and the panel 4 in cooperation. The whole device uses conventional and readily available materials, which greatly improves the ease of assembly and effectively reduces manufacturing costs. The core of the device is a piston assembly composed of a support cylinder 603 fixed by the mounting base 601 and a support rod 604 between the lower bearing seat 5 and the upper bearing seat 610 to achieve vibration reduction. The support cylinder 603 is filled with a mixture of silicone oil and carbonyl iron powder, which can flow and buffer through the through hole 607 of the partition 606 with the vibration of the equipment. The pressure sensor connected to the outer ring of the swivel bearing 611 can collect load data in real time, and the controller outputs current to adjust the electromagnetic coil 608 accordingly. The magnetic field alters the damping force of the mixed packing to precisely match load fluctuations, solving the problem of structural vibration caused by sudden load changes. Furthermore, the device can adapt to the winding requirements of iron cores of different weights without replacing any parts, significantly improving versatility and solving the problems of excessive size and inconvenience of traditional supports. In the non-winding state, the return spring 612 can push the mixed packing back to its original position through the through hole 607. The PTFE guide cylinder 609 ensures that the support cylinder 603 only extends and contracts axially, avoiding radial offset that could affect load-bearing accuracy. The external bellows 602 provides protection and sealing, comprehensively ensuring stable equipment operation.

[0037] Example 2: Please see Figure 2 and Figure 5 This is the second embodiment of the present utility model.

[0038] Specifically, the calibration mechanism 7 includes: a bearing rod 701, a calibration cylinder 702, a locking block 703, a force plate 704, a mounting shell 705, and a ceramic pressure actuator 706. The bearing rod 701 is fixedly installed on one side of the bellows 602 at the top of the bearing lower seat 5, and the calibration cylinder 702 is sleeved on the top of the bearing rod 701.

[0039] Furthermore, by forming a telescopic tube between the bearing rod 701 and the calibration tube 702, it is possible to further avoid the impact of offset on the load-bearing accuracy.

[0040] Specifically, a locking block 703 is fixedly installed at one end of the calibration cylinder 702 that penetrates into the bearing seat 610, and a force-bearing plate 704 is fixedly installed at the top inside the calibration cylinder 702.

[0041] Furthermore, the calibration cylinder 702 is rotatably engaged with the bearing seat 610 via the engaging block 703, thereby facilitating the disassembly and assembly of the bearing rod 701 and the calibration cylinder 702 for maintenance of the internal components.

[0042] Specifically, a mounting shell 705 is embedded at the top of the bearing rod 701, and a pressure ceramic actuator 706 is embedded inside the mounting shell 705.

[0043] Furthermore, in conjunction with the ceramic actuator 706, micron-level displacement compensation is achieved through the inverse piezoelectric effect, ensuring that the iron core always remains horizontal and coaxial with the winding machine spindle.

[0044] In use, the coordinated operation of the bearing rod 701 and the calibration cylinder 702 further enhances the balance of the entire support system. Simultaneously, the sensor connected to the swivel bearing 611 can monitor and collect the attitude deviation data during the iron core winding process in real time. When abnormal data is detected, the back-end control end will immediately activate the ceramic actuator 706 embedded in the mounting housing 705 to dynamically adjust the calibration cylinder 702. With the flatness of the force plate 704, the inverse piezoelectric effect of the ceramic actuator 706 can be ensured to be undisturbed, thereby achieving micron-level displacement compensation. This effectively solves the problem of iron core attitude deviation caused by installation errors and uneven loads in traditional supports. The entire process requires no manual adjustment and can respond automatically, avoiding the reduction in production efficiency caused by manual intervention.

[0045] In summary, the bearing rod 701 and the calibration cylinder 702 work together to improve the balance of the support system. The built-in sensor of the connecting bearing 611 monitors and collects the core winding posture deviation in real time. In case of abnormality, the back-end control end immediately activates the pressing ceramic actuator 706 embedded in the mounting shell 705 to dynamically adjust the calibration cylinder 702. The flatness of the force plate 704 ensures that the pressing ceramic actuator 706 can stably perform the inverse piezoelectric effect to achieve micron-level displacement compensation. This not only solves the problem of core posture deviation caused by installation errors and uneven loads in traditional supports from the root, but also eliminates the manual adjustment link through full automatic response, significantly improving production efficiency and core winding accuracy, and greatly reducing the error and efficiency loss caused by manual intervention.
