Automatic crimping equipment for primary terminal of adjustable mutual inductor

Abstract

Automatic crimping equipment for a primary terminal of an adjustable mutual inductor relates to the technical field of transformer terminal crimping and comprises a workbench, a driving structure arranged on the workbench, a crimping seat arranged on the workbench and a crimping structure arranged on the workbench. The driving structure drives the crimping structure to reciprocate towards the crimping seat. The crimping structure comprises a connecting seat, and a first crimping column and a second crimping column which are arranged at the lower end of the connecting seat and respectively correspond to different positions of a primary terminal on the crimping seat. The upper end of the connecting seat is fixed to the telescopic end of the driving structure. According to the structure, an automatic machine is adopted to crimp the primary terminal, and accurate control can be achieved. The structure is suitable for crimping of primary terminals of mutual inductors of various models, and the crimping efficiency and the yield are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of transformer terminal crimping, in particular to an automatic crimping device for an adjustable primary terminal of a transformer. Background technique [0002] The transformer for power system is a special transformer that transmits the information of high voltage and high current of the power grid to the secondary side of low voltage and small current for metering, measuring instruments, relay protection and automatic devices. The contact element, its primary winding is connected to the power grid, and the secondary winding is connected to the measuring instrument and the protection device, etc., and the transformer cooperates with the measuring instrument and the measuring device to measure the voltage, current and electric energy of the primary system; and the relay protection Cooperating with automatic devices, it can form electrical protection and automatic control for various faults in the power gri...

AI Technical Summary

Problems solved by technology

[0003] During the assembly and production of primary terminals of transformers, the primary terminals are generally pressed into the transformer shell by hand or simple tools. When crimping, uniform force cannot be guaranteed, which often leads to deformation or even damage of the primary terminals, resulting in low assembly efficiency. Low cost, high production cost, and the inability to accurately control the crimping force, unable to ensure that the terminal crimping is in place at one time, resulting in an inability to improve the yield rate
