A plasma torch holder for a sheet metal cutting machine, consisting of a body (1) with a mounting flange (4) for the head (5) of the plasma torch (2), at least one engagement member (10) provided on the body (3) for engaging the metal sheet surface and spacing the tip of the torch head (5) from the sheet, and a flange (6) for supporting said body (3) and the head (5) of the torch (2) on a tool holder column (7) of the machine, the head (5) of the plasma torch (2) being guided by a machine controller. Said holder is characterised in that the body (3) consists of two portions, i.e. an upper portion (8) supporting the mounting flange (4) for the head (5) of the plasma torch (2), as well as the supporting flange (6) for supporting said body (3) on the column (7), and a releasable lower portion (9) supporting the metal sheet-engaging member (10) of the holder (1), said releasable portion (9) being attached to the upper portion (8) via a device (11) for moving the lower portion (9) relative to the upper portion (8) in a direction parallel to the longitudinal axis of the head (5) of the plasma torch (2). |
