Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of transformer production equipment, specifically to a top pressure mechanism for transformer winding. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).
[0003] Currently, when producing medium-sized transformers, our factory first needs to place the winding bobbin onto a special mold, wrap the winding portion of the bobbin with insulating paper, and finally place the mold onto the transformer coil winding machine for winding. However, in actual production, it has been found that because the wound insulated flat wire has a certain strength, if the mold is not positioned, the reaction force of the insulated flat wire will cause the mold to slide on the winding machine during winding, resulting in winding failure. Therefore, this application provides a top-pressure mechanism for transformer winding to solve the above problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a top pressing mechanism for transformer winding. This mechanism can push and position the transformer winding mold, prevent the mold from sliding on the winding machine during the winding process, thereby avoiding winding failure. It can also assist the mold in being quickly fitted onto the winding machine, thereby improving the overall work efficiency. It is simple to operate and easy to use, and can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a top-pressing mechanism for transformer winding, including a mounting base, a horizontally arranged cylinder on the mounting base, a clamping plate for clamping a mold on the telescopic end of the cylinder, and slots on both ends of the upper end of the clamping plate corresponding to the mold. A strip groove is recessed in the part of the clamping plate corresponding to the mold towards the cylinder, and the strip groove is parallel to the slot. A guide member is provided on the mounting base to guide the clamping plate.
[0006] As a preferred embodiment of this utility model, the part of the clamp plate corresponding to the insertion end of the card slot is chamfered.
[0007] As a preferred embodiment of this utility model, a positioning block is provided on the side of the clamp plate away from the insertion end of the card slot.
[0008] As a preferred technical solution of this utility model, the guide includes a telescopic rod horizontally installed on the mounting base. The telescopic rod is arranged parallel to the cylinder, and the telescopic end of the telescopic rod is provided with a magnetic chuck. The clamping plate is provided with a limiting ring on the side corresponding to the magnetic chuck. The limiting ring is provided with a magnetic chuck piece inside that can magnetically attract the magnetic chuck.
[0009] In a preferred embodiment of this invention, the length of the telescopic rod is less than the length of the cylinder.
[0010] As a preferred embodiment of this invention, the edge of the magnetic chuck corresponding to the limiting ring is chamfered.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The transformer winding pressing mechanism of this utility model can push and position the transformer winding mold, preventing the mold from sliding on the winding machine during the winding process, thereby avoiding winding failure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3This utility model provides a technical solution: a top pressing mechanism for transformer winding, including a mounting base 1, a horizontally arranged cylinder 2 on the mounting base 1, a clamping plate 3 for clamping a mold at the telescopic end of the cylinder 2, and slots 31 are opened at both ends of the upper end of the clamping plate 3 corresponding to the mold. The part of the clamping plate 3 corresponding to the middle of the mold is recessed into a strip groove towards the cylinder 2, and the strip groove is parallel to the slot 31. Since there is a certain gap between the mold and the transformer winding frame, the mold for transformer winding can be inserted into the slot 31 from the insertion end until the insertion end of the mold contacts the positioning block 4. At this time, the mold and the internal frame are in a horizontal state. The mold and the transformer winding frame are fixed by bolts, and the ends of the bolts extend to the outside of the mold. The strip groove allows the bolts extending to the outside to have room for movement, so that the mold can be engaged with the slot 31.
[0019] The mounting base 1 is equipped with a guide component that guides the clamping plate 3. The guide component includes a telescopic rod 5 horizontally mounted on the mounting base 1. The telescopic rod 5 is arranged parallel to the cylinder 2, and the telescopic end of the telescopic rod 5 is equipped with a magnetic chuck 6. The clamping plate 3 is equipped with a limiting ring 7 on the side corresponding to the magnetic chuck 6. The limiting ring 7 is equipped with a magnetic chuck piece 8 that can magnetically attract the magnetic chuck 6. The cylinder 2 is controlled to extend, and the cylinder 2 pushes the mold to move horizontally through the clamping plate 3, thereby pushing the mold onto the transformer coil winding machine. During the extension of the cylinder 2, the clamping plate 3 drives the telescopic rod 5 to extend through the magnetic chuck piece 8 and the magnetic chuck 6. When the cylinder 2 continues to extend until the cylinder 2 transports the mold to the appropriate position through the clamping plate 3, when the telescopic rod 5 can no longer extend, the magnetic chuck piece 8 separates from the magnetic chuck 6. At this time, only the cylinder 2 pushes the mold.
[0020] Furthermore, the corresponding parts of the clamping plate 3 and the slot 31 are chamfered, which helps to quickly insert the mold into the slot 31 of the clamping plate 3.
[0021] Furthermore, a positioning block 4 is provided on the side of the clamping plate 3 away from the insertion end of the slot 31, which is used to limit the mold.
[0022] Furthermore, the length of the telescopic rod 5 is less than the length of the cylinder 2.
[0023] Furthermore, the edge of the magnetic chuck 6 corresponding to the limiting ring 7 is chamfered to facilitate the magnetic chuck 6 to be snapped into the limiting ring 7 and magnetically attracted to the magnetic chuck 8.
[0024] When using:
[0025] In the initial state, both cylinder 2 and telescopic rod 5 are in the shortened state, and magnetic chuck 6 and magnetic chuck 8 are magnetically attracted together;
[0026] Since there is a certain gap between the mold and the transformer winding skeleton, the transformer winding mold can be inserted into the slot 31 from the insertion end of the slot 31 until the insertion end of the mold contacts the positioning block 4. At this time, the mold and the internal skeleton are in a horizontal state.
[0027] The control cylinder 2 extends, and the cylinder 2 pushes the mold horizontally through the clamping plate 3, thereby pushing the mold onto the transformer coil winding machine;
[0028] During the extension of cylinder 2, clamping plate 3 drives telescopic rod 5 to extend through magnetic 8 and magnetic chuck 6;
[0029] As cylinder 2 continues to extend until it transports the mold to the appropriate position through clamping plate 3, when telescopic rod 5 can no longer extend, magnetic 8 separates from magnetic chuck 6. At this time, only cylinder 2 pushes the mold.
[0030] Then, control the external transformer coil winding machine to wind the coil.
[0031] This invention can push and position the mold for transformer winding, preventing the mold from sliding on the winding machine during the winding process, thus avoiding winding failure. It can also assist the mold in being quickly fitted onto the winding machine, thereby improving overall work efficiency. It is simple to operate and easy to use.
[0032] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
