Description

Technical Field

[0001] The utility model relates to transformer processing, in particular to an assembly jig for a small transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. It is widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] Among transformers, single-phase transformers below 20kV·A and three-phase transformers below 50kV·A are small transformers. For some assembled small transformers, in addition to coils (windings) and iron cores, their structures also include fixed brackets, insulation frames, insulation layers and other components. During assembly, operators need to install fixed iron cores, coils, insulation frames and other components on the fixed brackets to assemble the transformer. At present, during the assembly of transformers, the fixed brackets are not fixed, the positions of various components are difficult to confirm, and frequent adjustments are required during the connection, resulting in low assembly efficiency and quality. Utility Model Content

[0004] The utility model aims to overcome the problem of low assembly efficiency and quality of existing small transformers, and to provide an assembly jig that can improve the assembly efficiency and quality of small transformers.

[0005] The utility model adopts a technical solution to solve its technical problems: a small transformer assembly jig comprises a bottom plate, a plurality of positioning protrusions are longitudinally spaced on both sides of the bottom plate, the positioning protrusions on both sides correspond to each other, a limiting piece is provided on one side of each positioning protrusion on the bottom plate, one end of the limiting piece is rotatably connected to the bottom plate, the limiting piece is located above the positioning protrusion, the positioning protrusions on both sides of the bottom plate are matched one by one with the holes opened on the fixing bracket of the transformer, and operation through holes are provided on the front and rear middle parts of the bottom plate.

[0006] Optionally, the base plate is a rectangular steel plate, and the positioning protrusion is an elliptical column.

[0007] Optionally, a rotating shaft is vertically fixed to the bottom of one end of the limiting plate, and the limiting plate is rotatably connected to the bottom plate via the rotating shaft.

[0008] Optionally, the distance between the bottom of the limiting piece and the bottom plate is not less than the height of the positioning protrusion, and the depth of the hole opened on the fixing bracket of the transformer is the same as the distance between the bottom of the limiting piece and the bottom plate.

[0009] The usage and principle of the utility model are as follows: when in use, both ends of the fixed bracket of the transformer are put on the positioning protrusions, the limiting plate is rotated to cover the fixed bracket, the fixed bracket is positioned by the positioning protrusions and the limiting plate, and then other components are installed thereon, and with the help of operating through holes, these components are assembled into shape by means of cable ties, tapes, screws and later gluing, and after the transformer is formed, the limiting plate is rotated, the transformer is taken out, and the next transformer is assembled, thereby effectively improving the efficiency of transformer assembly; in addition, since the position of the fixed bracket is fixed, the subsequent component installation needs to be assembled according to the position of the fixed bracket, and the foot pitch and row pitch of the transformer can be better controlled, thereby effectively improving the quality of transformer assembly.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can effectively improve the assembly efficiency and assembly quality of small transformers. BRIEF DESCRIPTION OF THE DRAWINGS
