Description

Technical Field

[0001] This invention relates to the technical field of transformer core fixing equipment, and more particularly to a core fixing device for transformer core production. Background Technology

[0002] The transformer core is one of the core components of current transformers and voltage transformers. Compared with air cores, the high permeability of the core greatly enhances the magnetic coupling between the primary and secondary windings, enabling sufficient magnetic flux to be generated under a small excitation current, thereby inducing the required voltage or current on the secondary side, which is crucial for ensuring accuracy.

[0003] Existing iron core fixing devices often only have the function of fixing the iron core. When it is necessary to adjust the angle or flip the iron core, the iron core needs to be removed from the fixing device, flipped or adjusted, and then fixed. This greatly slows down the iron core production and processing steps and has a significant impact on the production efficiency of iron cores. Summary of the Invention

Two symmetrical moving platforms are provided between the two annular rails, and each moving platform has a circular groove. The inner walls of these grooves are flush with the inner walls of the liquid on the same side. The pressure rod is externally fixedly connected; an internal gear ring is fixedly connected to one of the annular rails; a synchronous motor is fixedly connected to the outside of each moving table; the output end of each synchronous motor is connected to a gear through a coupling; the gears mesh with the internal gear ring; and a rubber pad is fixedly connected to the side of each of the two main clamping blocks near the iron core body; the outside of the rubber pad is in contact with the outside of the iron core body; four symmetrical rollers are provided on the side of each of the two moving tables near the rubber pad; two symmetrical slots are opened on the side of each moving table away from the rollers; two symmetrical elastic springs are fixedly connected to the inner wall of each slot; and the outside of each elastic spring is slidably connected to the inner wall of the annular rail.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] The transformer core fixing device disclosed in this invention is mainly applied to scenarios where existing transformer core fixing devices lack effective flipping and angle adjustment measures.

[0023] Reference Figures 1-7 A core fixing device for transformer core production includes:

[0024] Platform 1;

[0025] The iron core body 2 has its bottom contact with the upper side of the support platform 1, and the bottom of the support platform 1 is connected to the base 3 by bolts.

[0026] Two symmetrical hydraulic rods 4 are located outside the iron core body 2. The output end of each hydraulic rod 4 is connected to an extension rod 5 by bolts. The opposite side of each extension rod 5 is connected to a main clamping block 6 by bolts, and both main clamping blocks 6 are located outside the iron core body 2.

[0027] The flipping and angle control module 7 is located outside the iron core body 2. The flipping and angle control module 7 is used to adjust the angle or flip the iron core body 2 after it is clamped and fixed.

[0028] Specifically, the device utilizes the flipping and angle control module 7 to allow the device to maintain the clamping and fixing of the iron core body 2 without removing the iron core body 2 from the fixing device, while simultaneously tilting or flipping the iron core body 2. This makes it easier for production personnel to process the iron core body 2, significantly improving production smoothness and efficiency.

[0029] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, the flipping and angle control module 7 includes two symmetrical annular rails 701, both located outside the core body 2. Two symmetrical connecting frames 702 are provided outside the two annular rails 701. The sides of the connecting frames 702 opposite to the annular rails 701 are bolted together. Two symmetrical stabilizing plates 703 are provided outside the support platform 1. A support frame 704 is bolted to the upper side of each stabilizing plate 703. Each support frame 704 has a sliding groove 705. An adaptive fixing module 8 is provided on each of the two extension rods 5. Movable plates 706 are slidably connected within each sliding groove 705. Each of the uprights 704 has two symmetrical slots 717 on its exterior. The inner walls of the slots 717 are slidably connected to the exterior of the movable plate 706. Each of the uprights 704 is equipped with an anti-deviation rod 707 and a threaded rod 708. The upper side of the anti-deviation rod 707 is bolted to the exterior of the upright 704, and the bottom of the anti-deviation rod 707 is bolted to the upper side of the stabilizing plate 703. A drive motor 709 is bolted to the upper side of the stabilizing plate 703. The output end of the drive motor 709 is connected to the bottom of the threaded rod 708 on the same side via a coupling. The upper side of the threaded rod 708 is rotatably connected to the exterior of the upright 704 on the same side via a bearing to prevent deviation. Both rod 707 and threaded rod 708 are provided with wing plates on their exteriors. The wing plates are bolted to the opposite side of the movable plate 706 on the same side. Both movable plates 706 have circular holes, and a rotating shaft 710 is rotatably connected to each hole via a bearing. One side of the rotating shaft 710 is bolted to the exterior of the connecting frame 702 on the same side, and the other side is bolted to a handle 711. An external gear ring 712 is bolted to the exterior of each rotating shaft 710, and a locking frame 713 is provided on the exterior of each external gear ring 712. Both locking frames 713 are slidably connected to the opposite side of the movable plate 706 on the same side, and the inner walls of the locking frames 713 are bolted to the exterior. The locking frame 713 is equipped with an arc-shaped rack 714, which is engaged with the outer gear ring 712. The outer side of the locking frame 713 is slidably connected with a guide buckle 715, and the guide buckle 715 is bolted to the opposite side of the movable plate 706 on the same side. The side of the two guide buckles 715 away from the outer gear ring 712 is bolted with a spring 716, and the end of the spring 716 away from the guide buckle 715 is bolted to the inner wall of the locking frame 713 on the same side. Two symmetrical moving platforms 718 are provided between the two annular rails 701. The two moving platforms 718 are provided with circular grooves, and the inner wall of the circular grooves is bolted to the outer side of the hydraulic rod 4 on the same side.One of the annular rails 701 is bolted to an internal gear ring 719. Synchronous motors 720 are bolted to the exterior of each moving platform 718. The output ends of the synchronous motors 720 are connected to gears 721 via couplings. The gears 721 mesh with the internal gear ring 719. Rubber pads 722 are bolted to the sides of the two main clamping blocks 6 closest to the iron core body 2. The exterior of the rubber pads 722 contacts the exterior of the iron core body 2. Four symmetrical rollers 723 are provided on the sides of each moving platform 718 closest to the rubber pads 722. Two symmetrical slots are formed on the sides of each moving platform 718 away from the rollers 723. Two symmetrical elastic springs 724 are bolted to the inner walls of each slot. The exterior of the elastic springs 724 is slidably connected to the inner wall of the annular rail 701.

[0030] Specifically, after the iron core body 2 is placed on the support platform 1, the hydraulic rod 4 is activated. The hydraulic rod 4 drives the main clamping block 6 on the extension rod 5, causing the rubber pad 722 on the main clamping block 6 to clamp the iron core body 2. The drive motor 709 is activated, driving the threaded rod 708 to rotate, causing the movable plate 706 to lift the iron core body 2 on the annular rail 701, thus beginning the production and processing of the iron core body 2. During the processing, the synchronous motor 720 is activated, driving the gear 721 meshing with the internal gear ring 719 to rotate, causing the moving table 71 to move. 8 drives the iron core body 2 to rotate on the annular rail 701, thereby rotating the unprocessed part on the same surface. After the surface is processed, the locking frame 713 is pushed against the elastic force of the spring 716, so that the arc rack 714 releases the lock on the outer toothed ring 712. The handle 711 is turned so that the annular rail 701 is deflected or flipped, so that the unprocessed surface of the iron core body 2 is flipped to a position that is easy to process, thereby making the unprocessed surface on the iron core body 2 easier to process. After the deflection or flipping is completed, the locking frame 713 is released so that the arc rack 714 relocks the outer toothed ring 712.

[0031] In specific application scenarios, the flipping and angle control module 7 is mainly used in the flipping and angle control process. That is, the flipping and angle control module 7 uses the ring rail 701, the moving table 718 and the rubber pad 722 to quickly and conveniently control the rotation of the iron core body 2, so that the processing personnel can more easily access the processing parts on the iron core body 2. The rotating shaft 710 and the connecting frame 702 can realize the flipping or deflection of the ring rail 701, so that the device can quickly deflect or flip the iron core body 2, reducing the operation complexity of the device. The locking frame 713 and the arc rack 714 can ensure that after the ring rail 701 is flipped or deflected, the ring rail 701 and the iron core body 2 will not shift due to gravity or other factors, which would affect the processing accuracy.

[0032] Reference Figure 7 In a preferred embodiment, both adaptive fixing modules 8 include a round rod 801, and both extension rods 5 have slots. The round rods 801 are bolted into the slots. A transmission plate 802 is slidably connected to the outside of each round rod 801. Two symmetrical narrow slots are formed on the outside of each extension rod 5, and the inner walls of these slots are slidably connected to the outside of the transmission plate 802. A boss 803 is bolted to the outside of each extension rod 5, and a hydraulic rod 804 is bolted to the outside of each boss 803. The output end of the hydraulic rod 804 is bolted to the outside of the transmission plate 802 on the same side. Furthermore, each of the two main clamping blocks 6 is rotatably connected to two symmetrical connecting rods 806 via bearings. The end of each connecting rod 806 away from the main clamping block 6 is rotatably connected to a secondary clamping block 807 via bearings. The side of each secondary clamping block 807 away from the transmission plate 802 is bolted to a rubber pad 808, which is in contact with the side of the iron core body 2 opposite to it. The outer surfaces of the two transmission plates 802 are rotatably connected to two symmetrical push-pull rods 805 via bearings, and the end of each push-pull rod 805 away from the transmission plate 802 is rotatably connected to the outer surface of the secondary clamping block 807 on the same side via bearings.

[0033] Specifically, when the output end of hydraulic rod 4 extends, the rubber pad 722 on the main clamping block 6 clamps the iron core body 2, and at the same time, hydraulic rod 804 is activated. The output end of hydraulic rod 804 extends, pushing the transmission plate 802 on the round rod 801 to move, thereby causing the push-pull rod 805 to push and pull the auxiliary clamping block 807, so that the rubber pad 808 on the auxiliary clamping block 807 adheres to the surface of the iron core body 2 under the pull of the connecting rod 806 and clamps the iron core body 2.

[0034] In specific application scenarios, the adaptive fixing module 8 is mainly suitable for the adaptive fixing link in the adaptive fixing process. That is, the adaptive fixing module 8 uses the secondary clamping block 807 and the connecting rod 806 to enable the device to push the transmission plate 802 through the hydraulic rod 804 to achieve angle control of the secondary clamping block 807. This makes the secondary clamping block 807 and the main clamping block 6 form a variable arc whole, which improves the device's ability to fix the iron core body 2. At the same time, it can also be adaptively adjusted according to the size of the iron core body 2, thus improving the versatility of the device.

[0035] Working principle: After the iron core body 2 is placed on the support platform 1, the hydraulic rod 4 is activated. The hydraulic rod 4 drives the main clamping block 6 on the extension rod 5, so that the rubber pad 722 on the main clamping block 6 clamps the iron core body 2. The drive motor 709 is activated, and the drive motor 709 drives the threaded rod 708 to rotate, so that the movable plate 706 drives the iron core body 2 on the annular rail 701 to rise, and the production and processing of the iron core body 2 begins. During the processing, the synchronous motor 720 is activated, and the synchronous motor 720 drives the gear 721 meshing with the internal gear ring 719 to rotate, so that the moving table 718 drives the iron core body 2 to rotate on the annular rail 701, thereby rotating the unprocessed part on the same surface. After the surface is processed, the spring force of the spring 716 is overcome to push the locking frame 713, so that the arc-shaped rack 714 is released. Locking the external gear ring 712, rotating the handle 711 causes the annular rail 701 to deflect or flip, turning the unprocessed surface of the iron core body 2 to a position that is easier to process, thus making the unprocessed surface on the iron core body 2 easier to process. After the deflection or flipping is completed, the locking frame 713 is released, and the arc-shaped rack 714 relocks the external gear ring 712. When the output end of the hydraulic rod 4 extends, the rubber pad 722 on the main clamping block 6 clamps the iron core body 2. At the same time, the hydraulic rod 804 is activated, and the output end of the hydraulic rod 804 extends, pushing the transmission plate 802 on the round rod 801 to move, thereby causing the push-pull rod 805 to push and pull the auxiliary clamping block 807, so that the rubber pad 808 on the auxiliary clamping block 807 adheres to the surface of the iron core body 2 under the pull of the connecting rod 806 and clamps the iron core body 2.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
