Embodiment
The present invention is described in detail with reference to the accompanying drawings.
The design proposal of native system is as follows:
UMAC (Universal Motion and Automation Controller) is a kind of modularization Turbo PMAC2 system-level controller of being made up of the European standard card of a cover 3U structure.Its control distribution and simple installation have built-in I/O and power module, and can pass through that communication modes such as USB, Ethernet or MACRO are realized and the high speed communication of principal computer.In this test macro, UMAC is mainly used in and finishes two functions: the one, and the control of frequency converter; The 2nd, the control of loading electricity consumption main shaft.And these two functions also mainly are to realize by the communication line of UMAC.In concrete implementation procedure, UMAC at first receives the dependent instruction that sends from host computer (as increasing or reduce the setpoint frequency etc. of frequency converter), by its output port signal is sent to frequency converter (at this moment then, in the relative parameters setting of frequency converter, the given way of frequency should be made as outside terminal), frequency converter will be finished corresponding operation.
Vibration is one of key index of main shaft dynamic perfromance, directly influences the suface processing quality of workpiece.DASP vibration and noise measuring system are mainly used in the vibration characteristics of measuring electric main shaft runtime system, degree of will speed up sensor sticks acquired signal on electric main shaft shell, analysis software by the DASP system carries out the FFT processing to signal, obtain the vibration signal spectrogram of electric chief axis system, thus can on-line monitoring the dynamic perfromance of electricity main shaft.As shown in Figure 1.Temperature rise is the important indicator of electric main shaft thermal characteristic, its concentrated expression the design of electric main shaft, manufacture level and quality of materials.The temperature of main shaft is too high can to influence running precision, can influence the bearing burn when serious, so the thermal characteristics of bearing restricts its raising rotating speed.Native system adopts thermocouple thermometry to measure the temperature rise of front-end of spindle bearing outer ring.As shown in Figure 2.
