During detection, will be parallel with running track 21 for 7 axis of steel pipe during detection, 7 pipe end of steel pipe is just placed to measuring main body,
The height of detection arm is adjusted to 7 axial location of steel pipe using arrangement for adjusting height, the dynamic measurement main body of level traveling device band is along steel
Near 7 pipe end of steel pipe, when reaching the tube wall of 7 pipe end of steel pipe by the position of light curtain part blocks, horizontal moving device stops 7 axis of pipe
Only.As shown in figure 5, in the installation process of sensor, due to there is alignment error, steel pipe 7 axis direction it cannot be guaranteed that
Sensor 1 is definitely consistent with 2 position of sensor, measures the alignment error for L3.By steel pipe 7 along axis rotation at least 180 degree, two
7 pipe end of steel pipe is all detected by group laser light curtain displacement transducer for one week, in 7 rotary course of steel pipe, two groups of laser light curtain displacements
The sensor same time detects that the tube wall at tube end diameter two ends stretches into length L1 of respective light curtain and L2 respectively.Control module 1
Bevel cun is cut according to what formula | L1+L3-L2 | calculated 7 pipe end of steel pipe, maximum bevel cun of cutting is cutting tiltedly for 7 pipe end of steel pipe
Value.
In two groups of 7 tube end diameters of laser light curtain displacement transducer direct detection steel pipe, 2 points of length for stretching into light curtain, draws
Maximum difference is the inclined value of cutting of 7 pipe end of steel pipe, and detection does not need 7 rotary speed of steel pipe or measurement rotational time, do not receive steel
7 rotary speed of pipe and the impact of timing, degree of accuracy are high, simple to operate.Steel pipe 7 pipe end may compare while steel pipe 7 rotates
2 points diametrically stretch into the length of respective light curtain, real-time operation, can quick output result.Compare one group of sensor detection of setting
When need at least to be rotated by 360 ° steel pipe 7, arranging when two sensors are detected only needs for steel pipe 7 to rotate 180 degree, also certain journey
Facilitate operation on degree, improve efficiency, especially in the face of some diameter is big, weight is big steel pipes 7 when, detection can be reduced difficult
Degree.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit this utility model, all at this
Any modification, equivalent and improvement that is made within the spirit and principle of utility model etc., should be included in this utility model
Protection domain within.
