ABSTRACT:
A tool positioner has a main support defining a pair of main pivot axes and ncluding a guide. Respective main cranks have inner ends pivoted at the main pivot axes on a support and outer ends pivoted to ends of respective links whose other ends are pivoted on a tool holder. This holder has an elongated stem longitudinally displaceable in the guide and carries a tool which can pivot about the axis of the stem and about another axis perpendicular thereto. The two cranks can be displaced independently of each other for swinging of the tool holder about either of the main pivot axes or for displacing it along the axis of the stem.
