Abstract
A machine for the simultaneous maching of a stack of plate-like workpieces has a frame with an overhead arm portion, a worktable below the arm portion, and a workpiece guidance assembly for moving the workpiece stack on the worktable. A rotary tool drive assembly and a riveting assembly are provided in the arm portion, and a tool storage assembly is spaced from the arm. A tool changer assembly has a pair of carrier rails extending from the tool storage assembly to adjacent the rotary tool drive assembly, and they are spaced to opposite sides thereof. A pair of tool carriers are reciprocatable on the rails for transporting tools between the tool storage assembly and the rotary tool drive assembly to effect insertion into and removal from said tool assembly of such tools. The carriers are vertically and horizontally movable relative to the rails to engage tools stored in the tool storage means and to cooperate with the rotary tool drive assembly to effect insertion of tools thereinto and removal of tools therefrom. A computer is operative to control the riveting and rotary tool drive assemblies and the tool changer and workpiece guidance assemblies.
