Composite machine tool integrating ultrasonic auxiliary grinding and laser machining and machining method

Abstract

The invention provides a composite machine tool integrating ultrasonic auxiliary grinding and laser machining and a machining method. Comprising a machine tool body, a double-shaft rotating workbench, a cross beam, an ultrasonic machining system, a laser machining system and a machine tool control cabinet, the cross beam is connected to the top of the machine tool body, the ultrasonic machining system and the laser machining system are arranged on the cross beam, and an ultrasonic machining main shaft of the ultrasonic machining system and a laser machining main shaft of the laser machining system can move in the vertical direction; the bottom of the double-shaft rotating workbench can move in the direction where the cross beam is located, the working face of the double-shaft rotating workbench is used for fixing a to-be-machined part, the working face can drive the to-be-machined part to rotate, outer circle grinding and plane grinding of the to-be-machined part through the ultrasonic machining system are completed, and laser drilling of the to-be-machined part through the laser machining system is completed. According to the invention, ultrasonic-assisted grinding machining and laser machining are combined, so that different machining processes of a workpiece on the same machine tool are completed, secondary clamping and repeated positioning of the workpiece are avoided, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of special processing, in particular to a composite machine tool and a processing method integrating ultrasonic-assisted grinding and laser processing. Background technique [0002] Ultrasonic assisted grinding is a processing method that combines ultrasonic vibration and grinding, and combines ultrasonic vibration system with traditional grinding equipment. Due to the addition of ultrasonic vibration in the grinding process, the contact state and action mechanism between the grinding wheel and the material change, from single grinding action to mechanical grinding action, high-frequency micro-impact and ultrasonic cavitation, etc. It is beneficial to reduce the action time between the grinding wheel and the workpiece, reduce the force between the grinding wheel and the workpiece, and finally achieve the purpose of reducing grinding heat, reducing grinding wheel wear, and improving machining accuracy and machining qua...

AI Technical Summary

Problems solved by technology

[0006] The processing (cylindrical grinding and hole making) of aero-engine components is usually carried out on two different machine tools, namely ultrasonic assisted grinding machine and femtosecond laser processing machine tool. There are problems of repeated positioning and clamping during the processing process, and the processing time too long
