Abstract

The invention discloses an efficient multi-freedom-degree ultrasonic vibration assisted double-sided laser machining device which is composed of a machine frame, an automatic feeding and discharging device, a double-sided laser machining device body, a three-freedom-degree moving device, an ultrasonic vibration assisting device, an assisted air blowing device, a controller and a monitoring device.The automatic feeding and discharging device can automatically move workpieces to all working positions. The double-sided laser machining device body can machine the two sides of each workpiece at the same time, the taper of the machined workpieces is reduced, and the single-side laser machining can be conducted. The three-freedom-degree moving device can rapidly move the workpieces. The ultrasonic vibration assisting device can realize the three-freedom-degree vibration of the workpieces and reduce recast layers, oxides, micro cracks and other defects in the laser machining process. The assisted air blowing device can reduce the splashing of melt during machining through coaxial and paraxial air blowing. The efficient multi-freedom-degree ultrasonic vibration assisted double-sided lasermachining device has the advantages of being reliable in work, high in automation degree, diversified in function, convenient to maintain, high in work efficiency, high in workpiece machining quality,high in applicability and the like.
