Torch angle setting apparatus

Abstract

A torch angle setting apparatus includes vertical links arranged in a vertical direction, the respective lower end of which is supported on a frame so as to be pivotally rotatable, and coupled with horizontal links at an upper end and an intermediate position of the vertical links for constituting a three-dimensionally parallel link. The torch angle setting apparatus also includes an inclining member constituted of a motor, an arm and a transmission member for inclining the vertical links by pivotally rotating the arm, a swinging member constituted of a swinging motor, a conducting member, splines for, including the inclining member, swinging conically the vertical links on fulcrums at the frame as a center, and a cutting torch moving in parallel to the vertical links. Accordingly, the simplification and miniaturization of the structure can be achieved in spite of the number of the hoses and cables connected to the torch when a bevel cutting is carried out with respect to the material to be cut by using a gas cutting torch or a plasma cutting torch.
