The reading of sensor 18 should be always zero, accidentally be loaded to waveform spring before avoiding experiment, can be suitably by the distance of upper and lower platen
It tunes up, the distance of upper and lower platen is made to be slightly larger than the natural length of waveform spring to be measured, when upper platen 17 pushes, high pressure-sizing
Force snesor 18 can measure the stage that one section of elastic force is zero, which can artificially reject, and not influence measurement result and essence
Degree.Dial gauge plays the role of correcting extensometer and subsidiary in measurement process.It, can be according at this time after dial gauge zeroing
The reading of extensometer is modified result.
According to the reading of dial gauge adjust upper and lower platen apart from when, the distance of upper and lower platen is tried not to be less than and be waited for
The natural length of waveform spring is surveyed, otherwise can lose partial data when measuring.
Using the ancillary test tooling of the present invention, substituted using the characteristic of electronic universal material testing machine automatic uniform speed load
The manual loading of the prior art is effectively avoided between machinery using the deformation during the direct measured waveform spring loads of extensometer
Test error caused by gap, collimation error etc.；Test error caused by prior art manual loading and single-point can be overcome to sample,
The precision of test is improved, and easy to operate, test curve is automatically recorded by computer, improves waveform spring performance evaluation
Accuracy and testing efficiency, further improve motor product design in waveform Spring Selection correctness, improve product and set
Count reliability.
