Study On Online Dynamic Balance Device Dontrol System Of Steel Conditioning Wheel

With the improvement of the Product precision and Machining efficiency, The Vibration that Grinding wheel produce in the machining process is becoming closely watched.As the important part,in the rotating mechanical system,the vibration caused by the unbalanced rotor causes equipment vibration,noise and damage.Based on the statistics,over 60 percents of all the machinery fault are due to unbalanced rotor.As to the imbalance of Grinding wheel not only affect the quality of surface、Product precision and Machining efficiency, but also accelerate the wear and tear of the grinder,reduce the time used of grinder and cost more.so,the control of unbalance is becoming more and more important. The installation can realize it without testing,so it has a bright future.For the steel conditioning wheel, it has new features of large replacement frequency, high efficient, stable and low cost in processing. Due to the significance in the study and economy,more and more experts focus on the balance technology on line and do a lot of experiments and study on it.Now,the main methods are balancing machine and balance on line.Because balancing machine is time-wast and complex,it is seldomly used.But the balance on line is convenient and effective,it is used extensively in manufacturing.The essay introduces present situation and development and fundamental of the balance on line,also give out the reasons that the rotor causes the unbalance.By detailed analysis,we ascertain the kind of unbalance.Based on the Influence coefficient method,we deduce and analysis the unbalance amplitude and phase.we successfully set up the model.we finish the FFT transform and make time domain transform frequency domain successfully, by visual basic. Based on USB7660 acquisition card,PC,PCI1243 motion control card and motor,we exploit the automatic balance system on line.The essay focuses on control system of online wheel balance device in steel conditioning.On the basis of Visual Basic,we realize the Measurement and acquisition of the signature of unbalance and benchmark、signal processing、motion control card’control to motor. We Complete a whole set of the control system of Online Wheel Balance device in Steel Conditioning,which can realize the balance quickly. In the premise of working, the control System is valid to restrain and Eliminate Vibration.It can reduce harm to the least or disappearance.So it is importance to the improvement of the Product precision and Machining efficiency.
