Laser-assisted horizontal three-dimensional ultrasonic elliptical vibration milling machine equipment and its working method

Abstract

A laser-assisted horizontal three-dimensional ultrasonic elliptical vibration milling machine and its working method belong to the field of ultrasonic vibration cutting technology, including an air-floating platform, an XYZ moving assembly, a micro-motion unit, a workpiece fixture, a laser-assisted processing device, and an ultrasonic electric spindle assembly to make. The laser-assisted horizontal three-dimensional ultrasonic elliptical vibration milling machine involved in the present invention solves the problem that only one-dimensional or two-dimensional ultrasonic vibration can be performed in the mainstream ultrasonic elliptical vibration milling machine in the market. The coupling problem during vibration, through the real-time monitoring and adjustment of the closed-loop control system, accurately controls the vibration trajectory of the ellipse, and through the combination of laser-assisted processing technology, the overall stability of the machine tool is strengthened, and the processing effect is further improved.

Problems solved by technology

[0005] The above two technologies are rarely used on milling machines. Ultrasonic elliptical vibration technology cannot solve the problem of decoupling in the orthogonal direction of the micro-motion unit during ultrasonic vibration, and when machining workpieces, affected by machining resistance, ultrasonic vibration When the feed direction is blocked, there is a deviation between the amplitude and the preset value, and it is difficult to accurately control the elliptical vibration trajectory. When the traditional ultrasonic elliptical vibration is used to process hard and brittle materials, the chips are mostly in the shape of particles, which reduces the machining accuracy, and the tool is also very easy to break. The application of laser-assisted processing technology can soften the workpiece to be processed, so that chips are produced in smooth strips, which ensures the quality of the processed surface, increases the service life of the tool, and improves the stability of the machine tool during processing
