Abstract
The invention discloses a novel method for indicating the central axis of an X-ray beam for nondestructive testing. The positioning method is not only simple and convenient to operate, but also accurate in positioning, and can be widely applied to central axis indication of X-ray beams of various accelerators.
Description
Technical field
The invention belongs to the accelerator technical field of nondestructive testing, be specifically related to a kind of new method of indicating Non-Destructive Testing with the X-ray beam central axis, and the employed a kind of specific purpose tool of this method.
Background technology
Utilize the X ray projection imaging to be widely used as a kind of important means of Non-Destructive Testing industrial flaw detection, X ray sees through tested workpiece and makes its imaging on film, the placement center of the keypoint part of tested workpiece and film should be on the central axis of X ray, x-ray dose rate maximum herein.The method of determining the X-ray beam central axis has multiple, and normally used method is to measure x-ray dose rate determining the central axis of X ray, but this method operation is more loaded down with trivial details, is difficult for accurately location.
Summary of the invention
The present invention is directed to the existing problem of central axis location technology of existing X ray, a kind of localization method easily and employed specific purpose tool thereof are provided.
X-ray beam central axis indicating means provided by the present invention uses a kind of specific purpose tool, i.e. positioning tool equipment nesting ring, and this frock is the ring-type right cylinder, built-in laser instrument, its external diameter is consistent with accelerating tube outlet opening internal diameter, and internal diameter is greater than the laser instrument external diameter.Its afterbody has cable aperture, and front and back are respectively established one group and adjusted screw hole, by adjusting screw to adjust the position of laser instrument.
A kind of X-ray beam central axis indicating means after X-ray beam central axis pre-determined bit, is located the adjustable laser indicator again.Key is that X-ray beam central axis pre-determined bit comprises two steps:
Described adjustable laser indicator positioning action method is: adjust the gib screw of adjustable laser indicator, its laser perpendicular to the X-ray beam central axis that sends is reflected, by the center of two vertical light targets through 45 degree.
The present invention by transmitting, realizes the location of X-ray beam central axis by using the positioning tool equipment nesting ring specific purpose tool, and is not only easy and simple to handle, and accurate positioning, can be widely used in all kinds of accelerator X-ray beam central axis indications.

Wherein, 1, positioning tool equipment nesting ring; 2, cable aperture; 3, screw hole is adjusted in the back; 4, preceding adjustment screw hole; 5, laser instrument; 6, x-ray target; 7, adjustable laser indicator; 8, catoptron; 9, laser beam; 10, vertical light target 1; 11, vertical light target 2.
Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further elaborated.
As shown in Figure 1, 2, positioning tool equipment nesting ring 1 is the employed specific purpose tool of a kind of X-ray beam central axis indicating means.This frock is the ring-type right cylinder, built-in laser instrument 5, and its external diameter is consistent with accelerating tube outlet opening internal diameter, and internal diameter is a bit larger tham the external diameter of laser instrument 5, to guarantee the adjustable positions of laser instrument 5.Its afterbody has cable aperture 2, and the cable by this hole provides power supply for laser instrument 5.Positioning tool equipment nesting ring 1 front and back are respectively established one group and are adjusted screw hole 3,4, and 3 of every group of designs of present embodiment evenly distribute with 120 degree, and rotary screw is to adjust the position of laser instrument 5.
The X-ray beam central axis determines that method is as follows:
A, positioning tool equipment nesting ring 1 centering.Laser instrument 5 is packed in the positioning tool equipment nesting ring 1 that processes, connect with the mains and make it luminous, again positioning tool equipment nesting ring 1 is installed on precision preferably on the lathe chuck, with 10 meters outer vertical planes of laser alignment, rotate lathe chuck, adjust positioning tool equipment nesting ring 1 side screw, laser spots is remained unchanged in rotation process, show that laser instrument 5 is coaxial with positioning tool equipment nesting ring 1.Pull down positioning tool equipment nesting ring 1 after adjustment finishes, positioning tool equipment nesting ring 1 screwing is fixed with fixing glue.
B, X-ray beam central axis pre-determined bit.Pull down the collimation awl of accelerating tube outlet opening, positioning tool equipment nesting ring 1 is embedded in the accelerating tube outlet opening, connect with the mains and make laser instrument 5 luminous, adjust the vertical light target 10 at 5 meters and the vertical light target 11 at 10 meters by light beam, their center is on the laser axis line, and rotational positioning frock nested rings 1, guarantee the invariant position of laser beam on vertical light target 10,11. Vertical light target 10,11 is for having the clear glass target of scale, be placed on the support and can about, about adjust the position.The adjustment back that finishes keeps accelerator motionless with vertical light target 10,11.Pull down positioning tool equipment nesting ring 1, load onto collimation awl, ionization chamber etc.
C, adjustable laser indicator location.As shown in Figure 3, adjustable laser indicator 7 is installed, and energized makes it send laser 9, and laser 9 is through the vertical light target 10,11 of 45 degree catoptron 8 reflected alignment, by adjusting the gib screw of laser designator 7, make the center of laser 9 bundles by vertical light target 10,11.The fixing gib screw of adjusting laser designator 7 is finished location and installation.
During use, the laser 9 that adjustable laser indicator 7 is sent through 8 reflections of 45 degree catoptrons after, aim at the keypoint part of tested workpiece, the central axis of the X-ray beam that x-ray target 6 sends has just been aimed at the keypoint part of tested workpiece.
