Abstract
The utility model relates to a modular ultrasonic dry coupling probe, it includes two or two above probe (1), probe line (5) and probe anchor clamps, the probe anchor clamps include overcoat (2), supporting spring (3) and gland (4), the bottom and supporting spring (3) of probe (1), the spacing system of spring is constituteed in gland (4), same surface is arranged in all probe (1), utilize ultrasonic surface wave to detect the work piece, it can be used to non-metallic composite ultrasonic wave nondestructive test, a surface that utilizes the work piece is detected a flaw, need not to scribble the couplant, easy operation, it is accurate to defect and defect depth detection.
Description
The utility model relates to the dried coupling probe of a kind of combination ultrasonic, belongs to the nonmetallic composite Ultrasonic Nondestructive with popping one's head in.
Because nonmetallic composite is bigger to hyperacoustic attenuation ratio, supersonic reflection method commonly used is difficult to detect nonmetallic composite.Generally use the ultrasonic pulse through transmission technique, detect a flaw, be about to two surfaces that two probes place workpiece respectively, remain aligning in the testing process by the ultrasound wave compressional wave, and vertical substantially with surface of the work.But this method can't be judged the degree of depth of defective, generally also need water to make couplant, Tan Shang result is subjected to operator's artificial factor in this way, and different operators is to popping one's head in applied pressure not simultaneously, and its testing result that obtains is just variant.In addition, many nonmetallic materials do not allow to be subjected to the pollution of water, wet goods couplant in detection, and the work of detecting a flaw sometimes can only be carried out on a surface, and require to judge the degree of depth of defective, and the ultrasonic pulse through transmission technique can't address these problems.Jap.P. JP-89242888 discloses a kind of apparatus and method of nonmetalliferous ore being detected a flaw with low-frequency ultrasonic waves, remains with the ultrasonic pulse through transmission technique and detects a flaw.
The purpose of this utility model is exactly at the deficiencies in the prior art and defective, the dried coupling probe of a kind of combination ultrasonic is proposed, be used for the nonmetallic composite Ultrasonic Nondestructive, it is achieved flaw detection under the situation of no couplant, utilize a surface of workpiece to detect a flaw, pollution-free to workpiece, and easy to operate.
The purpose of this utility model is achieved through the following technical solutions.
The dried coupling probe of a kind of combination ultrasonic, it comprises two or more probes, probe line and probe gripper, and probe gripper comprises overcoat, support spring and gland, and the bottom of probe and support spring, gland are formed the spring caging system.
Two or more probes place same surface, utilize the ultrasonic surface ripple to detect workpiece.
The advantage of the dried coupling probe of this combination ultrasonic is: it can be used for the nonmetallic composite Ultrasonic Nondestructive, utilize a surface of workpiece to detect a flaw, need not to be coated with couplant, pollution-free to workpiece, and it is easy to operate, detect accurately, can lean out the defective in the workpiece delicately, can differentiate the degree of depth of defective again.
Accompanying drawing 1 is the synoptic diagram of the dried coupling probe of combination ultrasonic.
Introduce embodiment below in conjunction with accompanying drawing:
The dried coupling probe of a kind of combination ultrasonic, it comprises two probes 1, probe line 5 and probe gripper, and probe gripper comprises overcoat 2, support spring 3 and gland 4, and the bottom of probe 1 and support spring 3, gland 4 are formed the spring caging system.
Two probes 1 place same surface, utilize the ultrasonic surface ripple to detect workpiece.
Workpiece is detected a flaw when using, and the operator only need make it touch surface of the work with the overcoat 2 of static probe to pressing down, and each pressure of popping one's head in is steady state value.The spring caging system can make different operators apply constant compression force to probe by the decrement of regulating spring.Utilize the ultrasonic surface ripple to detect workpiece, can lean out the defective in the workpiece delicately, can differentiate the degree of depth of defective again.Overcome the deficiencies in the prior art, and repeatedly be used for the detection of various nonmetallic materials workpiece, obtained testing result accurately.
Claims (2)
1, the dried coupling probe of a kind of combination ultrasonic, it is characterized in that it comprises two or more probes (1), probe line (5) and probe gripper, probe gripper comprises overcoat (2), support spring (3) and gland (4), and the bottom of probe (1) and support spring (3), gland (4) are formed the spring caging system.
2, probe according to claim 1 is characterized in that described two or more probes (1) place same surface, utilizes the ultrasonic surface ripple to detect workpiece.
