The invention discloses a high-amplitude
vibration amplitude variable rod for ultrasonic high-speed vibration auxiliary
processing. The high-amplitude
vibration amplitude variable rod is a whole pieceand includes a main body rod and a plurality of amplitude variable rod bodies, the main body rod is a
diameter variable rod arranged in the length direction of a tool
workbench, the amplitude variable rod bodies are the amplitude variable rod bodies with the rod
diameter reducing from the tool
workbench to a cutter pulling cutter box, and the bottom end of each amplitude variable rod body is connected to the variable
diameter position of the main body rod. When used, the energy can be concentrated on a smaller area because the rod diameter of each amplitude variable rod body reduces from thevibration penetrating-in end to the transferring-out end, the vibration is amplified and transmitted to the cutter pulling cutter box and a pulling cutter, the high vibration speed is achieved, high vibration speed requirements when a
turbine disk tenon groove is processed are met, and the surface quality is improved; and the amplitude is enlarged, the fact that cutter teeth are completely separated from a workpiece within a vibration frequency cycle, the possibility of a tool hitting the workpiece when the tool is returned from a non-
cut-off material is avoided, the
machining efficiency can be improved, the damage caused by the interference to the tool can be reduced, and the service life of the tool is prolonged.
