Abstract
A tool holder unit for a robot includes a pantograph linkage which is made up of a frame, a pair of parallel spaced links and a holder block. Each end of the parallel spaced links is connected to the holder block. The tool holder also includes a drive source which drives a tool and an offsetting member which offsets the gravitational force caused by the force of gravity on the tool. The tool moves relative to a workpiece when a force from the drive source moves the pantograph linkage. The pantograph linkage and offsetting member reduce the load on the drive source and move the tool quickly and smoothly.
