Wire Supporting Device and Electro-Discharge Drilling Machine

Abstract

The present invention discloses a wire supporting device and an electric discharge drilling machine. The device is arranged on the machine head, and the machine head includes a module base. An elevating block that is lifted and lowered under the drive of a first drive assembly is arranged on the module base, and a rotating head assembly is fixed on the elevating block. The wire supporting device includes a first guiding seat, and the first guiding seat is fixed to the elevating block. A first rod body is vertically arranged in the first guiding seat and can slide up and down along the first guiding seat. A first limiting block located at the upper end of the first guiding seat is fixed on the first rod body, and the first limiting block can abut against the upper end surface of the first guiding seat. A first fixing seat is fixedly connected to the first rod body and is located below the first guiding seat. A first wire supporting assembly is fixed on the first fixing seat, and a first guiding hole that is coaxial with the rotating head and is always located below the rotating head is arranged on the first wire supporting assembly. The wire supporting assembly and the rotating head assembly can both move followingly and relatively, saving costs and not affecting the descending distance of the rotating head assembly.
