Application described in the utility model based on to the electro spindle reliability test bench automatic centring device for dragging load

Using described based on right before the test to dragging the electro spindle reliability test bench automatic centring device of load to need This device is debugged, with going on smoothly for guarantee test process, the specific steps are as follows:

1. being measured before test to vibration limit value, i.e., according to proof stress i.e. test speed come Selection experiment permission The maximum value for misaligning situation and measure vibration limit value in this situation.Schilling or so misaligns situation more than limit value, operation examination Platform is tested, measures vibration values size at this time, and record；It enables again and misaligns situation up and down more than limit value, practice operation measures this When vibration values size, and record；Furthermore applied one by one by stress, find the resonance point of testing stand all appts, and herein Shi Jinhang vibration measure, if resonance point in selected stress, need to control program Labview in additionally incorporate a resonance when Alert process.

Vibration values in the case of two kinds are compared, selecting lesser one is more than limit value as alarm limits, Labview program alarm, test interrupt simultaneously being adjusted, the tested main shaft data measured in this way be all not comprising singular point can Use data.

2. detection device amount of feeding size measures, i.e., the survey to detection device to tested main shaft distance is needed before the test It takes, and feeding data is input in control program Labview；Also need the time run when overturning to Double-axis transmission motor 22 It measures, so that device flip angle when from detecting automatically to horizontal direction vertically be made just to be 90 degree, avoids overturning not In place or the excessive situation of overturning occurs.Detection device can perfectly detect tested main shaft in automatic detection and misalign in this way The case where, exclude not there is a situation where gap, interference or detection position when detection not pair, to exclude to generate examination by detection error Test the possibility of data singular point, and the warning device that excludes to rerun after being caused detection to adjust due to detection error is still triggered The case where, that is, avoid the occurrence of circulation alarm cause to test it is stuck.

3. first carrying out one-time detection to testing stand when on-test, and situation will be misaligned and be adjusted to minimum, and restart electricity Control cabinet and frequency converter 7 obtain electric；Then in the Labview program of industrial personal computer 5 input proof stress number, each stress test duration, The parameters such as alarm limits, the detection device amount of feeding, test starting.Situations such as preventing testing stand from running too early or delaying operation hair It is raw, it is ensured that test data is accurate.Since the whole flow process of testing stand operation is all automation control, do not needed when ending to test It is artificial to participate in, in off-test, it is only necessary to export test data preservation, close industrial personal computer 5 and power control cabinet and frequency converter 7.

Implementation steps listed above are to help test operator and understand and using the present apparatus, avoid going out in test Now since misoperation or preparation are insufficient.
