Abstract
A lightweight bevel head attachment for a torch cutting machine includes a horizontal support tray, a rotation assembly mounted under the support tray, a tilt assembly coupled to the rotation assembly for rotation therewith about a vertical axis, a torch holder carried and pivoted by the title assembly, and a rack-and-pinion lift assembly having a mounting plate for attachment to the cutting machine carriage. The tilt assembly includes a pair of link arms housing a pulley system for transmitting pivotal motion at an input shaft to an output shaft on which the torch holder is mounted. The bevel head attachment can provide bevel angles in a range of about +/−75 degrees.
