Description

소형 가변각 초음파 탐촉자 웨지{Small ultrasonic probe wedge with variable angle}Small ultrasonic probe wedge with variable angle

본 고안은 발전설비 등의 초음파 비파괴검사를 실시함에 있어서 터빈 블레이드 루트부나 발전기 지지환과 같이 형상이 복잡하여 여러 각도의 탐촉자를 사용하 여 검사 할 필요가 있거나 또는 부품이 작아서 초음파 탐촉자를 접촉할 면이 협소한 부분 등에 사용되어 탐촉자 접촉이 용이하게 하고 각도를 필요한 데로 변화시켜 가면서 검사를 할 수 있도록 한 소형 가변각 초음파 탐촉자 웨지에 관한 것이다.The present invention uses ultrasonic transducers of various angles due to complex shapes such as turbine blade roots and generator support rings. For small variable angle ultrasonic transducer wedges that need to be inspected or parts that are small and have a narrow surface to contact the ultrasonic transducer, so that the transducer can be easily contacted and the angle can be changed as needed. will be.

정밀한 초음파 비파괴검사를 위해서는 가장 적절한 탐상 각도를 선정하는 것이 매우 중요하며, 일반적으로는 45, 60, 70도로 고정된 표준형 경사각 탐촉자나 이와 같은 각도의 웨지를 별도로 제작해 탐촉자와 결합하여 사용하는 방법이 적용되고 있는데 대부분의 경우 국내에서는 위의 제품들을 수입에 의존하고 있다.It is very important to select the most suitable flaw detection angle for precise ultrasonic nondestructive examination. Generally, standard inclination probe fixed at 45, 60, 70 degrees or wedge of such angle is manufactured separately and combined with the probe. In most cases, the domestic products rely on imports.

가변각 탐촉자의 경우도 어떤 한 주파수의 탐촉자와 웨지를 일체형으로 제작된 제품을 사용하고 있으나 가격이 비싸고 크기를 작게 제작 할 수가 없어 터빈 블레이드 루트부나 발전기 지지환과 같이 형상이 복잡하여 여러 각도의 탐촉자를 사용할 필요가 있거나 또는 부품이 작아서 초음파 탐촉자를 접촉하기가 어려운 부분 등에는 거의 사용이 불가능한 실정이다.In case of variable angle transducer, the transducer and wedge of any one frequency are used as one-piece, but the price is expensive and the size cannot be made small. It is almost impossible to use the parts that need to be used or parts that are difficult to contact the ultrasonic transducer.

초음파 비파괴검사를 수행함에 있어서 결함 검출의 정밀도를 높이기 위해서는 결함에 초음파 빔이 수직으로 입사하도록 탐상각을 적용하여 미세한 결함에서도 큰 초음파 반사 신호가 나타나도록 해야 하나 기존의 45, 60, 70도의 표준형 경사각탐촉자나 별도로 제작된 웨지를 탐촉자와 결합하여 사용하는 방법은 각도 조절이 되지 않기 때문에 결함 방향에 정확히 수직으로 초음파 빔을 입사시킬 수 없는 경우가 많아 미세한 결함을 정밀하게 탐상하기에는 한계가 있다.In order to increase the accuracy of defect detection in performing ultrasonic nondestructive testing, a flaw detection angle should be applied so that the ultrasonic beam is incident perpendicularly to the defect so that a large ultrasonic reflection signal appears even at the minute defect. The method of using a probe or a wedge made separately and combined with a probe has a limitation in that it is impossible to precisely detect fine defects because the ultrasonic beam cannot be incident exactly perpendicular to the defect direction because the angle is not adjusted.

또한, 종래의 별도로 제작된 웨지는 45, 60, 70도의 표준형을 탐촉자와 나사방식으로 조립할 수 있도록 한 형태를 사용하고 있다. 이와 같은 탐촉자나 웨지 는 45, 60, 70도의 표준형 이외의 각도를 가진 탐촉자나 웨지가 필요한 경우 필요한 각도의 탐촉자나 웨지를 설계하여 제작해 사용해야 한다.In addition, the conventional wedge is manufactured using a form that can be assembled to the standard type of 45, 60, 70 degrees by the probe method and the screw method. Such probes or wedges If a probe or wedge with a non-standard angle of 45, 60, or 70 degrees is required, the probe or wedge must be designed and manufactured.

또한 종래의 가변각 탐촉자는 어떤 한 주파수의 탐촉자와 웨지가 일체형으로 된 형태를 사용하고 있다.In addition, the conventional variable angle transducer uses a form in which the transducer and the wedge of any one frequency are integrated.

그러나 이와 같은 종래의 가변각 탐촉자는 제작 기술이 매우 까다롭고, 필요한 주파수별로 별도로 여러 개를 제작해야 하며, 크기가 커서 탐촉자를 접촉할 수 있는 부분이 협소한 곳에는 사용할 수 없는 문제점이 있었다.However, such a conventional variable angle transducer has a very difficult manufacturing technology, and must be manufactured separately for each required frequency, and has a problem that it cannot be used in a place where the size of the variable contact transducer is large.

이와 같은 문제점을 개선하기 위하여 본 고안에서는 검사부위의 탐촉자 접촉면이 협소한 곳에서도 아주 미세한 결함도 검출이 가능하도록 가장 적절한 탐상각도를 선정하므로써 초음파 비파괴검사의 신뢰도를 극대화하도록 제작이 용이한 소형 가변각 초음파 탐촉자 웨지를 제공하는데 그 목적이 있다.In order to improve the above problems, the present invention selects the most suitable flaw detection angle so that even the smallest contact surface of the inspection part can detect even the smallest flaw. The purpose is to provide an ultrasonic transducer wedge.

또한 상기 고정부(120) 아래 바닥면은 탐촉자 접촉면이 협소한 부품에 사용이 가능하도록 소형(길이 20mm, 폭 15mm 이하)으로 가공한다.In addition, the bottom surface below the fixing part 120 is processed into a small (20mm in length, 15mm in width or less) to be used in the narrow parts of the transducer contact surface.

본 고안 소형 가변각 초음파 탐촉자 웨지는 도 2에 도시된 바와 같이 웨지 상부인 회전부(110)는 원기둥을 뉘어 놓은 형태로 위쪽 평면부는 암나사(111)가 가공되어 있어 나사방식으로 필요한 주파수의 탐촉자(140)를 결합 할 수 있으며, 아래쪽은 볼록한 곡면으로 되어 웨지 하부인 고정부에 끼워져 회전하므로써 탐상각도를 변화시킬 수 있도록 구성된 것이다.As the small variable angle ultrasonic transducer wedge of the present invention, as shown in FIG. ) Can be combined, and the lower part is a convex curved surface, which is fitted to the lower part of the wedge and rotates to change the flaw detection angle.

웨지 하부인 고정부(120)의 위쪽은 회전부가 결합되어 회전이 용이하도록 오목한 곡면이고 회전부가 상부로 쉽게 빠지지 않도록 반원보다 약간 크게 가공되도 록 하며, 아래 접촉면이 쉽게 마모되는 것을 방지하도록 좌, 우면에 스텐레스나 알루미늄 판을 부착하기 위한 나사구멍이 가공되고 특히 판의 좌측면에는 계산에 의하여 결정된 공칭굴절각을 쉽게 알 수 있도록 표기하게 된다.The upper portion of the fixing portion 120, which is the lower wedge, is a concave curved surface to facilitate rotation by combining the rotating portion, and may be slightly larger than the semicircle so that the rotating portion does not easily fall to the upper portion. In order to prevent the lower contact surface from being easily worn, the screw holes for attaching stainless steel plate or aluminum plate are machined on the left and right sides, and the nominal refractive angle determined by calculation is easily marked on the left side of the plate.

상기 웨지 상부(110)와 하부(120)의 모양에 있어서 상부가 원기둥을 뉘어 놓은 볼록한 형태를 원칙으로 하며, 상부의 모양이 오목하고 하부의 모양이 볼록한 형태이어도 무방하다.In the shape of the upper wedge 110 and the lower 120, the convex shape in which the upper portion of the cylinder is laid in principle, and the upper shape may be concave and the lower shape may be convex.

본 고안의 사용방법은 첨부도면 도 2 및 도 3에 도시된 바와 같이 원하는 주파수의 탐촉자(140)를 웨지 상부(110) 평면부의 암나사(111)에 결합하고 이것을 하부 고정부(120)의 좌측 혹은 우측에서 끼운 다음 좌, 우측에 마모 방지용 스텐레스나 알루미늄으로 된 고정판(130)을 부착하고 나사(131)를 이용하여 고정한다.In the method of the present invention, as shown in the accompanying drawings, FIGS. 2 and 3, the transducer 140 having the desired frequency is coupled to the female thread 111 of the flat portion of the upper wedge 110 and the left side of the lower fixing part 120 or Inserted from the right side and then attached to the left and right fixing plate 130 made of stainless steel or aluminum to prevent wear and fixed using a screw 131.
