Problems solved by technology
However, in the research on the composite machining method of ultrasonic vibration drilling, the drilling trajectory is mainly changed through the design of the horn (such as opening a chute on the horn). The disadvantage of this method is that the generated trajectory Limited to the designed horn, the generated trajectory cannot be precisely controlled

The invention relates to an ultrasonic vibration composite drilling device and a working method thereof. The ultrasonic vibration composite drilling device comprises a machine tool spindle and a sliding rail which are installed on a machine tool body; the sliding rail is provided with a workpiece clamp; the ultrasonic vibration composite drilling device further comprises a first ultrasonic vibration system and a second ultrasonic vibration system, and the first ultrasonic vibration system is installed between the machine tool spindle and a tool, and used for providing axial vibration for the tool; and the second ultrasonic vibration system is connected with the workpiece clamp and used for providing longitudinal vibration for a workpiece, and axial vibration generated by the tool is coupled with the longitudinal vibration generated by the workpiece to form a composite drilling track. The ultrasonic vibration composite drilling device provided by the invention is reasonable in design, the two ultrasonic vibration systems are used for providing vibration for the tool and the workpiece on the basis of original common drilling, meanwhile, the vibration direction of the tool is perpendicular to that of the workpiece, and the composite drilling track can be obtained through coupling; and the vibration track is accurately controlled by controlling the amplitude and the frequency, so that the machining quality of drilling is improved.
Description
Technical field: [0001] The invention relates to an ultrasonic vibration compound drilling device and a working method thereof. Background technique: [0002] Since Professor Junichiro Kumabe of Utsunomiya University in Japan proposed the theory of vibration drilling in 1954, scholars from various countries have carried out a lot of theoretical research and experimental analysis on vibration drilling, and have obtained many valuable research results and applied them in the processing field. Its principle is: due to the periodic separation of the cutting edge and the workpiece, the cutting force becomes a pulse force, so that the displacement of the drill bit does not change with time during the drilling process. The stationary effect and the pulse cutting force make the drill bit resist bending deformation Rigid effect to increase ability. Vibration drilling can effectively improve the processing condition of the cutting edge, reduce cutting force, cutting temperature, redu...
