Specific implementation mode
Technical scheme in the embodiment of the invention is clearly and completely described below in conjunction with the accompanying drawings, it is clear that described
Embodiment be only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ability
The every other embodiment that domain those of ordinary skill is obtained, shall fall within the protection scope of the present invention.
Embodiment 1
A kind of transition rail hot-forging forming overall size measuring device, as shown in Figure 1, described in including mainly fulcrum bearing 1, being set to
Circular guideway 2 in fulcrum bearing, the dot laser sensor 3 to move in a circle inside the circular guideway, and described in driving
The mobile mechanism that dot laser sensor 3 moves；The circular guideway 2 is internally provided with fluted disc 4, the mobile mechanism include with it is described
The motor 502 that the ratcheting gear 501 of fluted disc, the driving gear 501 rotate, the dot laser sensor 3 are fixed on the tooth
On wheel 501, the dot laser sensor 3 is connected with controller, and the controller is connected with display.
When measuring device works, rail stretches into inside circular guideway, and mobile mechanism drives dot laser sensor to be led along circle
It moves in a circle inside rail, rail profile is scanned.Based on laser triangulation principle, dot laser sensor is strafed every time
The spatial positional information of certain point is just extracted in Rail Surface, this location information is stored in a manner of two-dimensional coordinate.It is moving
Motivation structure drives dot laser sensor along during circular guideway moves one week, and dot laser sensor continuous trigger is extracted
The spatial positional information of Rail Surface series of points, no matter which kind of state detected rail is in, and will theoretically extract
Point Fitting fitting just can obtain a complete rail tunneling boring profile.But since rail is an abnormal workpieces, no argument swashs
Optical sensor at any orientation angle extraction Rail Surface point spatial positional information, must certain angles exist block, cause
Rail jaw and part web of the rail region can not be detected, as shown in Figure 2.
In each scan period, rail head, the web of the rail and the flange of rail spatial positional information of the acquisition of dot laser sensor are extracted, it will
The two-dimensional coordinate fitting splicing of these region points, just can obtain the profile information of corresponding true rail head, the web of the rail and the flange of rail, from
And realize the extraction to rail profile profile, as shown in Figure 3.
The rail profile profile of fitting and nominal contour high-precision matchs be verify workpiece whether the necessary means of qualification.
In the present embodiment, circular arc at the web of the rail is detected with Hough transform, such as Fig. 4（a）It is shown.In coordinate space x-y, institute
There is the straight line of point (xi, yi) to meet equation (xi-p)2+(yi-q)2=r2
, p, q, r are the abscissa in the center of circle, the ordinate in the center of circle, round radius respectively wherein in formula.For accepted standard wheel
The radius of exterior feature, circular arc is known.It is similar to round figure if having in coordinate space x-y, the curvature of all the points half on circle
Diameter r is centainly equal.
Hough transform searches for the circular arc F1H1 and F2H2 that radius of curvature at the web of the rail is 30mm, using least square fitting
The center of circle is rotated translation by the center of circle E1 and E2 for going out the circular arc around coordinate origin, after so that the rail profile profile of detection is ajusted, then with
Nominal contour matches, such as Fig. 4（b）It is shown.After the profile via controller matching comparison of scanning extraction, rail head is exported over the display
The size value that width, the web of the rail, the flange of rail are wide, rail is high, can determine that whether every spot size meets technical conditions requirement.
