Description

Technical Field

[0001] This utility model relates to the field of iron core processing technology, specifically to a transformer iron core winding machine. Background Technology

[0002] An instrument transformer is a device that uses the principle of electromagnetic induction to transmit and transform alternating current (AC) energy. It consists of two or more coils wound on a shared magnetic core. When the main winding is powered by an AC source, the current flowing through it generates an alternating magnetic field, which induces an electromotive force in the secondary winding. Instrument transformers are generally used in power systems, mainly for voltage boosting, current transformation, isolation, and impedance matching. The winding of the instrument transformer core is a crucial step in its manufacturing process. The core's main function is to conduct the magnetic field and reduce energy loss. The winding process involves tightly and evenly winding the coils onto the core to ensure the quality of insulation and power transmission.

[0003] In existing technologies, the position of the drum in a current transformer core winding machine cannot be adjusted. During the winding of the core, as the core is continuously wound, the amount of copper wire on the drum gradually decreases, resulting in a gradual reduction in the diameter of the copper wire drum. This causes the copper wire between the drum and the core to gradually lengthen, making it easy for the copper wire to sag and swing due to its own weight during the winding process. This results in uneven stress on the core during winding, thereby reducing the winding quality. Therefore, a current transformer core winding machine is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a current transformer core winding machine, which has advantages such as easy adjustment of the drum position. It solves the problem in existing current transformer core winding machines where the drum position cannot be adjusted, which easily causes the copper wire to sag and swing due to its own weight during the winding process, resulting in uneven force on the core during winding and thus reducing the winding quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a current transformer core winding machine, comprising a frame and a platform mounted on the top of the frame, a turntable being provided on the top of the platform, an installation shaft being fixedly mounted on the upper side of the turntable, a wire winding mechanism being provided on one side of the turntable, and a positioning mechanism being provided on the upper side of the installation shaft;

A copper wire reel is rotatably mounted on the lower side of the wire reel frame. A connecting rod is movably hinged to the output shaft of the first hydraulic rod. The end of the connecting rod away from the first hydraulic rod is movably hinged to the mounting plate.

[0007] The positioning mechanism includes a second hydraulic rod mounted on the upper side of the platform, a connecting plate fixedly mounted on the output shaft of the second hydraulic rod, and a positioning block rotatably mounted on the bottom of the connecting plate, which is opposite to the position of the mounting shaft.

By starting the reduction motor 3, the turntable 5 is driven to rotate, which in turn drives the iron core on the mounting shaft 6 to rotate, facilitating winding.

[0024] In this embodiment, a wire winding mechanism 7 is provided on one side of the turntable 5. The wire winding mechanism 7 includes a mounting plate 701 slidably mounted on the top of the platform 2 and a first hydraulic rod 708 mounted on the outside of the platform 2.

The end of the connecting rod 709 away from the first hydraulic rod 708 is movably hinged to the mounting plate 701.

[0025] The mounting plate 701 has a first fixed bracket 702 fixedly mounted on its top. An electric push rod 703 is fixedly mounted on the inner side of the first fixed bracket 702. A connecting piece 704 is fixedly mounted on the output shaft of the electric push rod 703. The upper end of the wire reel 705 is fixedly connected to the connecting piece 704. By starting the electric push rod 703, the connecting piece 704 can be moved, and the wire reel 705 can be moved, thereby adjusting the height of the copper wire reel 706. In addition, a fixed plate 707 is fixedly connected to the top side of the platform 2, and a first hydraulic rod 708 is fixedly mounted on the top of the fixed plate 707.

[0026] It should be noted that a guide rail 710 is fixedly installed on the top of the platform 2, and a slider 711 is slidably fitted on the outer side of the guide rail 710. The slider 711 is fixedly connected to the bottom of the mounting plate 701. The cooperation between the guide rail 710 and the slider 711 can guide the mounting plate 701 and improve the stability of the structure.

[0027] In this embodiment, a positioning mechanism 8 is provided on the upper side of the mounting shaft 6.

[0029] It should be noted that the positioning block 804 and the connecting plate 803 are connected by bearings.

[0030] The working principle of the above embodiments is as follows:

[0031] During the winding process, the diameter of the copper wire coil 706 gradually decreases, causing the copper wire between the copper wire coil 706 and the iron core to gradually lengthen. By activating the electric push rod 703, the connecting piece 704 can be moved, which in turn moves the wire coil holder 705, thereby adjusting the height of the copper wire coil 706. By activating the first hydraulic rod 708, the connecting rod 709 is moved, which in turn moves the mounting plate 701 and causes the slider 711 to slide along the outside of the guide rail 710, thereby adjusting the distance between the copper wire coil 706 and the iron core to ensure that the tension of the copper wire remains stable.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented.
