Abstract:
1. An ultrasound device for the treatment of surfaces and welded joints, comprising: a housing having a front end and a butt end, and having a plurality of shaped slots formed therein, a reciprocally moveable sleeve attached to said housing, said sleeve containing: a reciprocally moveable attachment attached to an operating end of said sleeve, said attachment having a mounting mechanism that allows mounting of a detachable working head thereon, said working head having striker tips for treating surfaces and welded joints, an oscillation velocity transformer that is connected at one end to said ultrasonic transducer, and is in contact at its other end with said striker tips of said working head, wherein the connection between the oscillation velocity transformer and the ultrasonic transducer is formed at a nodal plane, a pin positioned in a pin slot on said housing, said pin slot having a front edge that corresponds to said front end of said housing, and a back edge that corresponds to said butt end of said housing, said pin anchoring said sleeve to said housing and limiting the movement of said sleeve, said pin being biased towards the front edge of said slot by a spring located between the operational end of said sleeve and the butt end of said housing, and a moveable spigot that provides a predetermined contact force between the ultrasound device and a work surface, said spigot having spigot pins, wherein said spigot pins are inserted into said plurality of shaped slots in order to restrict the axial movement of said spigot, thereby providing added compression or tension to said spring in order to provide said predetermined contact force.
