A transformer circular iron core assembling device

Abstract

The invention discloses a transformer circular iron core assembling device, comprising a base, an assembling cylinder and a positioning pin. The base is in a hollow cylindrical shape with one opened end, a limiting boss is arranged at the outer bottom of the base, and a positioning through hole is arranged at the inner bottom of the base. The assembly cylinder is coaxially arranged in the inside of the base, and the corresponding positioning through hole on the assembly cylinder is provided with a through groove along the axial direction; The positioning pin is inserted into the positioning through hole and the through slot; Assembling the outer silicon steel sheets according to the mode of stacking and assembling the silicon steel sheets from the outside and the inside sequentially, and then assembling the inner silicon steel sheets and the special screws according to the order of replacing the assembling cylinder with the inner silicon steel sheets and replacing the special screws with the positioning pins; Compared with the traditional transformer core assembly device and method, the invention has the advantages of high assembly accuracy, high assembly efficiency, simple structure, easy replacement, low operation cost and effective positioning of special screws.

Description

technical field [0001] The invention belongs to the technical field of transformer iron core assembly, in particular to a transformer circular iron core assembly device. Background technique [0002] The iron core is one of the most important parts in the transformer. The assembly accuracy of the iron core greatly affects the use effect of the entire transformer. The iron core of the transformer is actually composed of several thin silicon steel sheets that are repeatedly stacked and assembled. Since the thickness of a single silicon steel sheet is far smaller than the aperture of the circular through hole of the transformer coil skeleton, and the distance between the transformer special screw and the circular through hole of the transformer coil skeleton must be controlled, in the absence of a dedicated iron core assembly device , Usually the circular iron core is assembled by hand. The following problems often exist in the manual assembly of circular iron cores. The first...

AI Technical Summary

Problems solved by technology

The following problems often exist in the manual assembly of circular iron cores. The first is that the accuracy of manual assembly is not high. Due to the large number of silicon steel sheets that need to be stacked and assembled in the circular through hole of the transformer coil frame, in the case of manual assembly, it is easy to cause The assembly of silicon steel sheets is random, which leads to the inconsistent shape of each transformer core. At the same time, the stacked and assembled silicon steel sheets are generally less than the specified number, which ultimately affects the quality of the entire transformer, causing the transformer to iron when it is working. Core vibration, heat generation, unstable performance parameters and other problems; secondly, the efficiency of manual assembly is low. Since the circular iron core needs to be stacked and assembled with a large number of silicon steel sheets, when stacking and assembling the silicon steel sheets, it is also necessary to ensure that the silicon steel sheets are stacked and assembled. The distance between the left special screw hole and the center of the circular through hole of the transformer coil skeleton, so in the process of manual assembly, it is necessary to manually adjust the placement position of the silicon steel sheet at any time, resulting in low assembly efficiency

Aiming at the problems of low assembly accuracy and low assembly efficiency in the traditional transformer circular iron core assembly process, the invention discloses a transformer circular iron core assembly device
