Compared with prior art, the present invention has following advantage:
1. drive the swing of measured object solid of revolution by the roller rolling friction that links to each other with elastics wing mechanism, simplified operations such as clamping that measured object solid of revolution and elastics wing mechanism connect firmly, center line, whole test process is simplified greatly; Deducted complicated frock clamp simultaneously, economy, versatility improve, and especially to the measured object solid of revolution complex-shaped, that length is very long, superiority is more obvious.
2. owing to adopt the V-type frame to add the structure of roller, testee is placed and is in a kind of free state, guaranteed that in measuring process measured object solid of revolution nature rotates around self, avoided clamping, center line to cause the measured object solid of revolution to depart from the error that self rotating shaft is rotated, improved measuring accuracy.
3. in design, adopt elastics wing mechanism to be fixed on the roller, need not each the measurement elastics wing mechanism directly is connected with the measured object solid of revolution, the good reproducibility of system has improved relative measuring accuracy.
