Abstract
A single-chip computer controlled ultrasonic processing circuit. The device adopts a computer to detect ultrasonic current, voltage and power signals, controls the frequency and power of ultrasonic waves in real time, controls the whole machine in timing and the like, and enables the ultrasonic vibration to be in the optimal resonance state all the time, thereby simplifying operation procedures and improving processing efficiency. In addition, because a computer is adopted instead of an analog frequency selection network adopted by the traditional ultrasonic machine, the frequency tracking range is improved and can reach more than +/-5 KHz.
Description
The invention belongs to special process field, relate to ultrasound wave control and take place.
Ultrasound wave has been widely used in the processing and the polishing of mould and hard brittle material as a kind of job operation.The method that can be applied to the ultrasound wave automatic frequency tracking at present has following three kinds: the method that (1) adopts self-excitation to amplify.As the ultrasonic machining buffing machine of U.S. Pat 4063512 and the various automatic frequency trackings that domestic most of unit produced, but this kind method starting of oscillation instability, poor reliability; (2) phase-locked ring type.As the CSJ-100 type ultrasonic carver that Beijing new technology is developed, the control effect is better, but the tracking frequencies scope is narrower, to having relatively high expectations of instrument, can not adapt to the wide variation of frequency; (3) computer control type.The DUOMAX-II type of Japanese EDMAS company and the MP-I type buffing machine of mould factory, Nanjing development are only arranged, (being the imitated type of DUMAX-II).This type adopts at ultrasonic transducer increase a slice piezoelectric ceramic piece and detects, follows the tracks of ultrasonic frequency.This method control is effective, and the frequency-tracking scope is big.But owing to be the method that adopts special transducer, so cost is higher, and be difficult for the control under the high-power condition of realization, (having only the product of power) less than 50W.
The object of the invention is to provide a kind of some ball bearing made using of application and need not special transducer and can realize automatic frequency tracking, can realize the supersonic machining apparatus of high-power control simultaneously.
Accompanying drawing helps to describe in detail the present invention.
Accompanying drawing is the schematic diagram of single-chip computer controlled ultrasonic processing unit (plant).It is shown and keyboard circuit 2 by one-chip computer 1, program storage 3, and power control circuit 4, power supply 5, frequency output circuit 6, power amplification circuit 7, ultrasonic transducer 8, voltage detecting transformer 9, current sense transformer 10, voltage comparator 11,12 is formed.After computing machine 1 sends a superaudio signal, change by frequency output circuit 6, power amplification circuit 7 and to change into power signal, be applied on the transducer 8.Detect voltage, the current signal of transducer simultaneously by comparer 11,12, send into computing machine.Computing machine is adjusted output frequency according to the phase differential of voltage, electric current, makes it phase differential for minimum, thereby makes ultrasonic vibration be in optimum resonant state.By detecting transformer 9,10 phase shifts that produced, can adjust and need not phase-shift circuit by software.After manually passing through keyboard input circuit 2 setpoint power outputs, computing machine constantly passes through power control circuit 4, power amplification circuit 7 and detects the equiva lent impedance of transducer 8, and constantly adjust the voltage of power supply 5, make power amplification circuit 7 all-the-time stable on artificial setting value.Thereby reached the stable output of power.Resistance R
1, R
2Act as level translation, the output signal of transformer 9,10 is transformed into satisfies the signal that the computing machine level requires.
In the present invention, carry out phase-detection, and adjust phase place by software owing to the method that does not adopt special transducer adopts ball bearing made using, thereby reduced cost, obtain good control effect simultaneously, simplified running program, improved working (machining) efficiency and processing stability.And, can realize the control (more than the 500W) of more high-power output.In addition,, therefore improved the frequency-tracking scope owing to adopt computing machine rather than carry out frequency control with the simulation frequency selection network that ultrasonic drilling machine adopted in the past, can reach ± more than the 5KHz.
