Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a transformer shell grinding device. Background Art

[0002] Transformer is the basic equipment for power transmission and distribution, widely used in industries, agriculture, transportation, urban communities and other fields. It is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. In the manufacturing process of transformer, due to process or other reasons (such as shearing, gas, and mechanical processing during unloading), there may be burrs, sharp corners and other defects on the transformer shell, and the defective parts need to be polished. At present, the grinding heads of most grinding devices on the market are fixed in position, and can only grind transformers in a single direction, which is less practical. In addition, the shapes and sizes of transformers are different, resulting in multiple angles of the transformer. The grinding head in a fixed position cannot effectively grind the corners of the transformer, resulting in incomplete grinding of the transformer, making the grinding effect of the transformer poor.
