Ultrasonic nondestructive testing wedge block

Abstract

The invention discloses an ultrasonic nondestructive testing wedge block. The wedge block used in the prior art is fixed and the angle of a refraction angle cannot be changed flexibly. The ultrasonic nondestructive testing wedge block provided by the invention comprises a first-level wedge block, a second-level wedge block, couplant guide tube ports, ultrasonic probe ports, couplant through holes and sound-absorbing materials, wherein an upper flat surface of the first-level wedge block is provided with the ultrasonic probe ports; the other side faces of the first-level wedge block are in flexible connection with one side face of the second-level wedge block through couplant, and the couplant guide tube ports are arranged on the side faces of the second-level wedge block except the bottom surface; and the second-level wedge block is provided with the couplant through holes, one outlet of the couplant through holes is connected with the couplant guide tube port, and the other side faces of the second-level wedge block except the top and bottom sides are provided with the acoustic materials. The ultrasonic nondestructive testing wedge block provided by the invention has the advantages of increasing the efficiency of the ultrasonic nondestructive testing and improving the convenience of the ultrasonic nondestructive testing.

Description

technical field [0001] The invention belongs to the field of ultrasonic nondestructive testing, in particular to an ultrasonic nondestructive testing wedge. Background technique [0002] Wedges are one of the commonly used components in ultrasonic nondestructive testing. Usually, wedges can be used to change the angle at which the ultrasonic beam is incident on the workpiece, so as to achieve the purpose of nondestructive testing. At present, wedges are frequently used in the field of ultrasonic nondestructive testing, but conventional wedges have the following two disadvantages. First of all, the currently used wedge is a whole. If you want to change the direction of the ultrasonic beam incident on the workpiece during use, you must move the whole wedge, which is very inflexible to use. Secondly, the currently used wedges are fixed and cannot flexibly change the angle of refraction. If it is necessary to realize multi-angle scanning in use, multiple different wedges must b...

Problems solved by technology

First of all, the currently used wedge is a whole. If you want to change the direction of the ultrasonic beam incident on the workpiece during use, you must move the entire wedge, which is very inflexible to use.

Secondly, the currently used wedges are fixed and cannot flexibly change the angle of refraction. If multi-angle scanning is required in use, multiple different wedges must be replaced, which is not efficient.
