The utility model relates to the technical field of transformers, in particular to a
punching device for
transformer installation, which comprises a
punching box, a
punching mechanism is arranged in the punching box, the punching mechanism is composed of a
drill bit, a driving motor, a telescopic rod, an electric push rod, a connecting plate and a rotating column, and a moving mechanism is arranged in the punching box. The device comprises a
trepanning box, a moving mechanism is arranged in the
trepanning box, a moving
assembly and a
servo motor are arranged in the moving mechanism, a labor-saving clamping mechanism is arranged at the bottom in the
trepanning box, a labor-saving clamping part and a clamping plate are arranged in the labor-saving clamping mechanism, a dismounting mechanism is arranged in the trepanning box, and the dismounting mechanism is composed of a dismounting component and an elastic clamping block. According to the
transformer mounting rack punching device, the punching device can rapidly punch the two ends of a
transformer mounting rack, so that the working efficiency of the punching device in use is improved, the labor intensity of the punching device when clamping the transformer mounting rack is reduced, and the convenience degree of the punching device when a
drill bit is disassembled and assembled is improved.
