Description
Technical field
The present invention relates to a kind of detection control apparatus, particularly about a kind of UT (Ultrasonic Testing) instrument probe pressure control device of hand-held.
Background technology
At present, in rolling stock and accessory production run, no matter be large parts UT (Ultrasonic Testing), or the weld seam supersonic detection of steel construction piece, the overwhelming majority all adopts the mode of the manual flaw detection of A type pulse reflection.In the process that adopts A type pulse reflection UT (Ultrasonic Testing), the size of judging workpiece, defect mainly with the echo height of defective and two indexs of length as benchmark, judge whether workpiece is qualified, then will be take a certain reflection wave height of certain equivalent (size) defective of regulation as boundary.Vary in size if impose on the pressure of probe, make so the height of the reflection wave that the defective workpiece of tool produces different with length, what namely react is exactly varying in size of this workpiece, defect.
Adopt in the process of manual A type pulse reflection UT (Ultrasonic Testing), for same detector device, the height of flaw echo and length, mainly be applied to the impact of " pressure " size on the probe, in order to guarantee that probe is good with the workpiece coupling, must apply certain pressure to probe is 2N～5N generally speaking.For same defective, the height of the large then reflection wave of applied pressure and length are also just larger, the height of the little then reflection wave of applied pressure and length are then just little, if therefore corresponding be same defective of closing on decision boundaries, different people may provide two kinds of diametrically opposite result of determination.
During general on-the-spot flaw detection operation, the flaw detection worker is the sensation with oneself basically, when guaranteeing as far as possible flaw detection and the pressure size during sensitivity check be consistent, but the operation technique of different people is different and feel there are differences, only operate with feeling, examine mutually, specially inspection or when sampling observation, near the defective the grade estimation boundary, can draw different conclusions, and bring great dispute.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of hand-held and can overcome UT (Ultrasonic Testing) instrument probe pressure control device human factor, that can control probe pressure.
For achieving the above object, the present invention takes following technical scheme: a kind of UT (Ultrasonic Testing) instrument probe pressure control device, it is characterized in that: it comprises a substrate, the bottom surface of described substrate is symmetrically arranged with four dovetail grooves, be provided with a pillar in each described dovetail groove, the top of each described pillar is provided with a set nut, the bottom of each described pillar is fixedly connected with a ball, be provided with a round platform at described B.B.P center, an end that circumferentially is connected with a spring of described round platform, the other end of described spring is supported on the top of UT (Ultrasonic Testing) instrument probe.
During circumferential size that the space that four described pillars surround equals to pop one's head in, described pillar is fixedly connected in the dovetail groove of described B.B.P by described set nut, the spring that is connected to described B.B.P is the nature extended configuration, the bottom of described spring is supported on the top of probe, the ball bottom that makes described column bottom is connected with the probe bottom by flaw detection workpiece maintenance certain displacement distance.
Ball when described column bottom contacts with the workpiece of UT (Ultrasonic Testing) instrument probe bottom, and the force value that described spring is subject to is 3.5 ± 0.3N.
The material of described substrate adopts a kind of the processing in rigid plastic and the steel material, described substrate be shaped as a kind of in rectangle, square and the circle.
Four described dovetail grooves are in twos at B.B.P and relatively are symmetrical arranged.
Four described dovetail grooves are cornerwise direction interval at B.B.P and are symmetrical arranged.
Described pillar adopts steel material to process, and the shape of described pillar adopts a kind of in right cylinder, square body and the pitch circle cylinder.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is owing to adopt spring and pillar co-controlling to exert pressure to the UT (Ultrasonic Testing) instrument probe, when therefore effectively having solved on-the-spot hand-held ultrasound defectoscope probe, impose on the uncontrollable technical barrier of UT (Ultrasonic Testing) instrument probe pressure size, realized the quantification of pressure size.2, therefore the present invention goes for the UT (Ultrasonic Testing) instrument probe of different size, different size owing to be provided with the pillar that connects by dovetail groove at B.B.P, and it uses flexibility and reliability, to guarantee the more smooth and easy of flaw detection process.3, the present invention is owing to the supporting role by pillar, the pressure stability that the UT (Ultrasonic Testing) instrument probe is subject to, in the flaw detection process especially in the decision process, can not cause artificial pressure to increase or reduce, therefore can guarantee the stability of defect reflection wave height, solve because pressure varies in size and produced the different trouble of result of determination.4, the present invention increases for fear of the frictional resistance between UT (Ultrasonic Testing) instrument probe and workpiece, employing is installed ball in a column bottom, therefore can guarantee that UT (Ultrasonic Testing) instrument probe and flaw detection workpiece realization point contact, and can reduce again the frictional resistance that produces in the flaw detection process.5, the present invention because employing fixes control UT (Ultrasonic Testing) instrument probe by four mobile pillars, therefore can avoid the phenomenon of UT (Ultrasonic Testing) instrument probe generation deflection and eccentric wear in the flaw detection process.When 6, device of the present invention is detected a flaw operation at the scene, go for putting down, horizontal, stand, push up and the various flaw detections position that tilts, no matter the UT (Ultrasonic Testing) instrument probe is on which kind of position, all can effectively control the pressure size of probe, therefore overcome the limitation that briquetting can only be applied to the planimetric position.7, device of the present invention is in the flaw detection operation, be convenient to realize the correct execution to technological procedure, be more convenient for tackling the inspection of on-the-spot result of detection, be conducive to guarantee the quality of the work of detecting a flaw, the difference of having avoided human factor that the result is judged difference and having produced, thus the flaw detection quality guaranteed.The present invention uses among can being widely used in UT (Ultrasonic Testing) Site Detection hand-manipulated.
