Precision machining of ultrasonic amplitude transformer is investigated in thispaper. ultrasonic turning devices with double tools in opposite-direction feed andwith single tool in regular feed are developed. Transistor generator with frequency-. tracing system is used. when the ultrasonic cutting too1 operates continuously for14o minutes, its highest temperature is but 38to and its frequency floats by only 29Hz.Test results show that machining precision may reach IT7-IT8, surface rou-gliness Ra may reach O.4-O.8pm and machining efficiency may be increased 15times. Precision machining of ultrasonic amplitude transformer can thus be achievedLy an ultrasonic lathe. 相似文献

The theory of design and characteristics of the vertical ultrasonic honing device are presented. The designing thought that the abrasive sticks be expanded during machine tool operation and the honing bar and the honing head base should not vibrate is proposed. Two solutions are adopted: (1) a piezoelectric transducer and ultrasoinc amplitude trensformer with a cylindrical hole in the center; (2) a 1/4 wavelength sound insulation bar at the vibration node of a vibration disc, to which the honing bar is assembled. Temperature increase of vertical ultrasonic honing device is measured, and method of decreasing the temperature is adopted. The highest temperature of the device can be controlled to 40℃, and frequency floating reduced by 39.6%. Finally, the fields of the device is mentioned. 相似文献

立式超声珩磨设备的研制 总被引：2，自引：2，他引：0
本文介绍了立式超声珩磨设备的设计理论和特点．在研制卧式超声珩磨设备的基础上,我们提出了在机床不停机的条件下使油石胀开以及珩磨杆、珩磨头体均不振动的设计思想,并采取了两条相应的措施：（1）采用有圆柱孔的压电换能器和变幅杆;（2）在弯曲振动圆盘的圆周节线处制有四分之一波长的声绝缘杆,然后将珩磨杆安装在声绝缘杆上．对立式超声珩磨设备的温升进行了测试,并采取了相应的降温措施,立式超声珩磨设备的最高温度可以控制在40℃,频率漂移量减少39．6％．最后,讨论了立式超声珩磨设备的应用范围． 相似文献
