Abstract: The invention relates to a workpiece positioner and assembly therefore which optimizes workpiece rotation for manufacturing processes, and specifically for use with an industrial robot. In general, the workpiece positioner assembly is supported on a base. The workpiece positioner assembly is rectangular in shape and includes drive arms and idler arms between which workpieces are supported. Due to the unique shape of the workpiece positioner assembly, the workpiece-to-workpiece rotational clearance can be reduced to zero due in part to the position of cross tubing from the drive end of the workpiece positioner assembly to the idler end of the workpiece positioner assembly. The cross tubing does not interfere with the workpiece rotational area thereby allowing workpiece size and orientation to be increased without affecting positioner swing or operation height.

Abstract: A wire brake for a robotic welding torch includes an adapter which is attached to the upper end of the welding torch and which includes an adapter bore through which the wire electrode is inserted. A cylinder body is threadably attached to the adapter and includes a reciprocating piston having a piston stem which is movable into a brake position engaging the wire electrode so as to hold the wire electrode against axial movement within the adapter bore.

Abstract: The tool of the present invention includes a compliance guide having a cylindrical vertical bore extending therethrough. Slidably mounted within the bore is a tool holder which is free to slide vertically, but which is held against lateral movement within the bore. Attached to the tool holder is a tool having a dauber pad at its lower end. A nipple is threaded within a vertical bore in the tool holder and extends upwardly therefrom through an aperture in a closure plate which fits over the upper end of the vertical bore in the compliance guide. A nut is threaded over the nipple above the closure plate and a spring below the closure plate yieldably urges the nipple and the tool holder downwardly until the nut engages the closure plate. Fluid is introduced through the nipple and extends downwardly to the dauber pad which absorbs the liquid and applies it to the work surface.
