Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, and in particular to a transformer processing device. 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). Transformer manufacturing involves various equipment used for components such as the coils and iron core, including operations such as clamping, polishing, and drilling.

[0003] In the process of processing transformer cores, clamping devices are often required. Rigid clamps (such as bolt-fastened clamps or pneumatic clamps) are generally used. These clamps typically have a fixed claw structure and can only accommodate cores of specific shapes. For irregularly shaped cores, such as those in the shape of a "mountain", the clamping height and angle cannot be changed during clamping, and the clamping components in contact with the core cannot be adjusted or adaptively adjusted. If the transformer core deforms during the clamping process, the contact area will become smaller, resulting in a decrease in clamping force. In addition, the lack of a support platform with a hollow structure makes it difficult to observe and operate after the equipment is clamped and placed, and it is impossible to compensate for core deformation during the clamping process.
