Abstract
Abstract A contacting device for an installation for ultrasonic dimensional treatment of workpieces includes a frame having a base; a longitudinal carriage positioned on the frame; a transverse displacement carriage positioned on the base of the frame; an acoustic head electrically coupled with an ultrasonic generator and positioned on the longitudinal displacement carriage, the acoustic head having a tool; a working table positioned on the transverse displacement carriage; a mechanism for controlling vertical feed of the working table to and from the tool; and a mechanism for vertically moving and applying contact force to the working table. The mechanism for vertically moving and applying contact force includes a lever rocker having a roller support mounted on one end of the lever rocker and contacting the working table, and a pressure roller mounted on the other end of the lever rocker so that the roller support lifts the working table and applies contacting force to the working table. The mechanism for controlling vertical feed includes a vertical aerostatic guide affixed to the transverse displacement carriage, an inner member affixed to the working table and disposed inside the vertical aerostatic guide so that the working table is vertically movable, and a mechanism for measuring depth of the took in the workpiece, which includes an electrical contact, having a first blocking contact mounted on the working table and a second blocking contact mounted on a lever which is mounted by one end in a joint and connected by the other end to a drive.
