Abstract
The utility model provides an ultrasonic flaw detection near field region length adjustment device which is composed of a water film base plate and an adjusting bolt. A square probe hole is arranged in the middle of the water film base plate, a bolt hole is arranged on the periphery of the probe hole, and an ultrasonic probe penetrating in the probe hole of the water film base plate is connected onto the water film base plate through the adjusting bolt. A couplant filling hole and a water inlet hole are arranged on the ultrasonic probe, and a couplant layer is arranged between the ultrasonic probe and a piece to be explored. The penetrating-in length of the probe in the probe hole can be adjusted through the adjusting bolt to offset abrasion loss of a probe emission face to enable probe near field region length to always keep in a certain scope, guarantee sensitivity of the probe, improve flaw detection accuracy, avoid or reduce exploration leakage accidents and guarantee quality acceptability of steel products after leaving a factory.
Description
Technical field
The utility model belongs to metal supersonic detection device field, and particularly a kind of steel UT (Ultrasonic Testing) can be adjusted the near field region probe and visited the device of distance between the workpiece.
Background technology
According to examination and test of products standard code, must carry out UT (Ultrasonic Testing) before steel dispatch from the factory and detect qualified can dispatching from the factory.The used probe of product flaw detection of different size, its near-zone length is different, this probe quality assurance parameter just is fixed after probe completes.Owing in product flaw detection process, mostly adopt the contact method flaw detection, probe with directly contacted by the flaw detection steel surface, therefore will cause the wearing and tearing of probe front end surface of contact, and along with the aggravation of the contact surface abrasion degree of popping one's head in, its near-zone length is also gradually changing.After may wear to a certain degree; The variation of matter will take place in the near-zone length of probe, thereby causes the sensitivity of probe to descend, and is difficult to satisfy the accuracy of detection requirement; Flaw detection work can't be proceeded; The probe of having to change has again directly influenced serviceable life of probe, has increased use cost.And wearing and tearing after probe in a single day can not get timely replacing, then will have a strong impact on the accuracy of steel carrying out flaw detection, cause Lou spy accident.
Summary of the invention
The utility model aims to provide a kind ofly can adjust probe distance as required, thereby guarantees probe sensitivity, avoids the UT (Ultrasonic Testing) near-zone length adjusting gear of leak spy accident.
For this reason, the solution taked of the utility model is:
A kind of UT (Ultrasonic Testing) near-zone length adjusting gear is characterized in that, is made up of moisture film backing plate and adjusting bolt; Have square probe hole in the middle of the moisture film backing plate, be provided with bolt hole around the probe hole, the ultrasonic probe that stretches in moisture film backing plate probe hole is connected on the moisture film backing plate through regulating bolt.
Said ultrasonic probe is provided with couplant filling orifice and inlet opening.
Said ultrasonic probe and quilt are visited between the workpiece and are provided with the couplant layer.
The beneficial effect of the utility model is:
Because the utility model has been set up the moisture film backing plate between probe and quilt spy workpiece; Can adjust probe and in probe hole, go deep into length through regulating bolt, thereby remedy the wear extent of the probe surface of emission, the probe near-zone length is remained within the specific limits; Guaranteed the stable of probe sensitivity; Improve the flaw detection precision, stop or reduce to leak the spy accident, guarantee the outgoing qualification rate of steel.
Description of drawings
Fig. 1 is a UT (Ultrasonic Testing) near-zone length adjusting gear structural representation.
Fig. 2 is a UT (Ultrasonic Testing) near-zone length adjusting gear vertical view.
Among the figure: couplant filling orifice 1, probe 2, inlet opening 3, adjusting bolt 4, couplant layer 5, moisture film backing plate 6, quilt are visited workpiece 7.
Embodiment
Visible by accompanying drawing, the utility model UT (Ultrasonic Testing) near-zone length adjusting gear mainly is made up of moisture film backing plate 6 and 4 on bolt of adjusting.Have in the centre of moisture film backing plate 6 one with probe 2 low profile and the corresponding square probe hole of size, be processed with 4 bolts hole that have internal thread on every side at probe hole.The bottom of probe 2 is stretched in the probe hole of moisture film backing plate 6; Be connected through regulating bolt 4 between ultrasonic probe 2 and the moisture film backing plate 6; And can regulate bolt 4 adjustment probes 2 and visited the distance between the workpiece 7, thereby the near-zone length of probe 2 can be remained in the relatively-stationary scope through degree of tightness.In order to improve and keep the sensitivity of probe 2, be filled with couplant layer 5 at ultrasonic probe 2 and between by spy workpiece 7.
Simultaneously, match, on ultrasonic probe 2, also be respectively arranged with couplant filling orifice 1 and inlet opening 3 with couplant layer 5 and moisture film backing plate 6.
Claims (3)
1. a UT (Ultrasonic Testing) near-zone length adjusting gear is characterized in that, is made up of moisture film backing plate and adjusting bolt; Have square probe hole in the middle of the moisture film backing plate, be provided with bolt hole around the probe hole, the ultrasonic probe that stretches in moisture film backing plate probe hole is connected on the moisture film backing plate through regulating bolt.
