Preferably, the steel pipe specification processing that first probe module and the second probe module detect as needed is matched
Limiting slot.
Compared with prior art, the present invention has following advantageous effect：The relative motion that the present invention is contacted with workpiece is paid
It is to roll to pay, is not kept at a distance by wear-resisting boots, can realize that the probe posture of different size steel pipe adapts to automatically, nothing needs to change
Component simplifies and changes specification debugging flow, shortens debug time.Probe adhesive force be independent stressed system, a whole set of make-up machine
When structure pressure changes, probe mounting base still is able to fit closely steel pipe.The relative motion that probe holder is contacted with workpiece is paid equal
It is paid to roll, solves wear-resisting boots direct friction workpiece and bounce and jitter problem easily occurs, substantially increase the detection of equipment
The signal-to-noise ratio index of stability and detection signal.Probe module keeps its idler wheel and the close of workpiece inner wall to connect by tension spring
It touches, independent of sleeve mechanism pressure, when sleeve mechanism pressure changes, probe module still is able to fit closely steel pipe；
It is to roll to pay that wear-resisting boots direct friction workpiece is avoided easily to beat and tremble that the relative motion that probe holder is contacted with workpiece, which is paid,
Dynamic problem substantially increases the detection stability of equipment and the signal-to-noise ratio index of detection signal.The present invention can operate in steel pipe
The layering of wall end, vertical wound, horizontal triage are surveyed, and are particularly suitable for not moving axially, are once completed the detection of full circle week, structure slightly becomes
Shape can also apply to outer wall of steel pipe detection.
