背景技术Background technique
超声加工技术已经比较广泛地应用于功能陶瓷、光学玻璃和先进复合材料的加工，较好地解决了传统方法加工时产生的切削力大、切削温度高、加工表面质量差和刀具磨损严重等问题。超声加工机理是在传统切削过程基础上，利用超声加工振动系统为刀具施加上频率在15-40kHz范围内的超声波频率振动，通过超声复合轨迹的刀具的锤击、磨削和空化的复合作用，加工过程中的切削力和切削热大幅降低，从而有效地提高了加工表面质量并降低了刀具磨损。Ultrasonic processing technology has been widely used in the processing of functional ceramics, optical glass and advanced composite materials, and it has solved the problems of large cutting force, high cutting temperature, poor surface quality and severe tool wear caused by traditional methods. . The ultrasonic machining mechanism is based on the traditional cutting process, using the ultrasonic machining vibration system to apply ultrasonic frequency vibration in the range of 15-40kHz to the tool, and the combined effects of hammering, grinding and cavitation of the tool through the ultrasonic compound track , The cutting force and cutting heat in the machining process are greatly reduced, thereby effectively improving the quality of the machined surface and reducing tool wear.
实现上述超声加工优势的关键是在刀具上施加以较大振幅。超声加工振动系统的谐振频率与超声电源电信号频率一致时，输出振幅和系统功率均会达到最大值。当力热负载波动变化时，两者频率之间存在频率差，频率差越大，超声加工振动系统的输出振幅和系统功率越小。带宽则是指系统功率最大值一半所对应的两个频率之间的频率差，能够表征超声加工振动系统输出振幅受频率差影响的敏感程度。带宽越大，频率差导致的输出振幅降低的程度越小，但是其代价为振动系统的机械品质因数越低，能量损耗越大。The key to achieving the above advantages of ultrasonic machining is to apply a larger amplitude to the tool. When the resonance frequency of the ultrasonic machining vibration system is consistent with the frequency of the ultrasonic power electrical signal, the output amplitude and system power will both reach the maximum. When the force and heat load fluctuates, there is a frequency difference between the two frequencies. The larger the frequency difference, the smaller the output amplitude and system power of the ultrasonic machining vibration system. Bandwidth refers to the frequency difference between the two frequencies corresponding to half of the maximum system power, which can characterize the sensitivity of the output amplitude of the ultrasonic machining vibration system to the frequency difference. The larger the bandwidth, the smaller the reduction in output amplitude caused by the frequency difference, but the price is that the lower the mechanical quality factor of the vibration system, the greater the energy loss.
目前解决频率差造成的振幅降低的方法是使用具有频率跟踪功能的超声电源，自动调节超声电源电信号频率与振动系统谐振频率一致。但对于力热负载频繁变化而导致谐振频率频繁变化的振动系统而言，频率跟踪功能的跟踪速度依然较慢，最终导致振动系统在谐振和失谐状态之间频繁变换。The current method to solve the amplitude reduction caused by the frequency difference is to use an ultrasonic power source with frequency tracking function, and automatically adjust the frequency of the ultrasonic power source's electrical signal to be consistent with the resonance frequency of the vibration system. However, for the vibration system whose resonant frequency changes frequently due to the frequent changes of force and heat load, the tracking speed of the frequency tracking function is still relatively slow, which eventually causes the vibration system to frequently change between resonance and detuning states.
现有超声加工设备，均在追求极高的机械品质因数，导致振动系统带宽范 围极窄，加工过程中的力热负载的波动造成超声加工振动系统谐振频率的波动，最终导致超声电源和振动系统之间失谐，输出振幅时有时无，加工稳定性和加工质量降低。Existing ultrasonic processing equipment is pursuing a very high mechanical quality factor, resulting in a very narrow bandwidth of the vibration system. The fluctuation of the force and heat load during the processing causes the fluctuation of the resonance frequency of the ultrasonic processing vibration system, which ultimately leads to the ultrasonic power supply and the vibration system. Detuning between the two, the output amplitude sometimes disappears, and the processing stability and processing quality are reduced.
因此，需要开发一种装置，以便能按需要拓展换能器带宽，从根本上提高振动系统的稳定性，扩大带宽的同时保证适合的机械品质因数。Therefore, it is necessary to develop a device that can expand the bandwidth of the transducer as required, fundamentally improve the stability of the vibration system, and expand the bandwidth while ensuring a suitable mechanical quality factor.
