Abstract
The invention discloses an ultrasonic laser composite dressing device for a superabrasive grinding wheel. The ultrasonic laser composite dressing device is mainly formed by an ultrasonic vibration dressing system, a laser transmitting system and a lathe bed. A laser transmitter transmits energy to a laser focusing head with a focusing head fixing and adjusting device through optical fibers, laser beams are focused during work to heat the rotating grinding wheel in front of a dressing point at proper energy density for proper heating time, an ultrasonic generator transmits an ultrasonic frequency signal to an ultrasonic transducer, the ultrasonic frequency signal is converted into mechanical vibration through the transducer to be transmitted to an amplitude-change pole, waves, generating longitudinal vibration, of the amplitude-change pole will be decomposed at the position, where a diamond slot is formed, of the small end, the vibration type involves longitudinal vibration and bending vibration, composite elliptical ultrasonic vibration is formed at the point of a diamond dressing stylus for dressing, and after the dressing stylus completely disengages from the grinding wheel, the dressing stylus will be moved to the position where dressing is started for the next time and starts dressing for the next round. In the dressing process, under the recombination action of ultrasonic vibration and laser auxiliary heating, removal of partial materials of the grinding wheel is changed from brittle removal into plastic removal, cutting force is reduced, abrasion to the dressing stylus is reduced, and the dressing efficiency and dressing result are improved.
