Description
Technical field
The present invention relates to a kind of circumferentially positioned methods, and in particular to one kind positions motor-car by orthogonal cross laser line projection
The method of group hole-bored axle from end to end manual ultrasonic flaw defect circumferential position.
Background technique
Under the background of China railways speed raising, it is especially desirable to be examined to the high-speed railway EMU for reaching maintenance mileage
It repairs, the maintenance proposed adoption status maintenance and periodic inspection of China express railway EMU combine, the maintenance system based on status maintenance
Degree.Status maintenance refers to that determine EMU sets business state using monitoring and diagnostic device, declines component or accidental life to performance
The mode that failure repairs;Periodically repair be preventative maintenance, traction power and transport agent through the prescribed time-limit (with the time or
It is accumulative with running kilometre) utilization, regularly checked and adjusted, restore the performance of motor-car, prevent the generation of failure, with guarantor
Hinder operation security.In maintenance, need to carry out ultrasonic examination inspection to axle, the axle that high-speed railway EMU uses is base
This hole-bored axle from end to end, needing to pop one's head in protrude into carries out complete detection inside axle.Well known portable detection equipment flaw detection when pair
The defective locations detected are all the methods that feeler lever tape measuring Position Approximate either fuzzy estimate is pulled out after using blaze,
It obtains a range position where defect, can not accurately obtain the specific location of defect, so as to defect when flaw detection
Accuracy and accuracy cannot be guaranteed.
Summary of the invention
The technical problem to be solved by the present invention is to the shortcomings that overcoming the prior art, it is hollow provide a kind of positioning EMU
The method of axle manual ultrasonic flaw defect circumferential position, this method is simple and easy, can fast and accurately obtain defect circumferential direction
The accuracy of flaw detection has been effectively ensured in position.
It is lacked in order to solve the above technical problems, the present invention provides a kind of positioning EMU hole-bored axle from end to end manual ultrasonic flaw
The method for falling into circumferential position, specifically includes the following steps:
(1) dial is arranged in the periphery of the EMU hole-bored axle from end to end with circumferential defect, in which:
The one side of dial is that the face β is dial plane, and angle index is provided on the face β, and the centre bore of dial is circle O1, β
Angle index on face surrounds round O2, the round O1With O2With one heart；
(2) make straight line L along its length on the EMU hole-bored axle from end to end surface with circumferential defect1, in which:
Straight line L1Perpendicular to the face dial β and with circle O1It is tangent, point of contact O；
(3) it crosses O point and makees circle O1Tangent line L2；
(4) in the face dial β, make L by point of contact O2Vertical line L3, in which:
Vertical line L3By circle O1The center of circle, and vertical line L3With great circle O2There is an intersection point；
(5) ' ten ' wordline of orthogonal laser line is projected to the face dial β, so that ' ten ' wordline intersections are overlapped with point of contact O, ' ten ' wordline
Vertical line and straight line L1It is overlapped, then projects to the face β laser rays and be overlapped with L3, laser rays and circle O2Intersection, intersection point are denoted as A point,
Reading A point circumferential direction angle is γ；
(6) it is the angle where defective locations that γ, which subtracts corresponding 0 ° axial angle of deviation of popping one's head in,.
The technical solution that the present invention further limits is:
Further, the method for aforementioned positioning EMU hole-bored axle from end to end manual ultrasonic flaw defect circumferential position, in step (1)
Angle index is 0-360 °.
The beneficial effects of the present invention are:
Well known portable detection equipment is all to pull out feeler lever skin after using blaze to the defective locations detected in flaw detection
The method that ruler measures Position Approximate either fuzzy estimate, obtains a range position where defect, can not be accurate
The specific location of defect out, so that cannot be guaranteed when flaw detection to the accuracy of defect and accuracy.Use this method letter of the present invention
It is single easy, defect circumferential position can be fast and accurately obtained, the accuracy of flaw detection has been effectively ensured.
