Background

The ultrasonic wave can sensitively reflect the information in the measured object, and the stress accumulated in the measured object can be nondestructively measured by using the ultrasonic wave. The stress measuring instrument based on ultrasonic acoustic elasticity theory is a mechanical quantitative detection product which utilizes the inherent relation between the ultrasonic wave speed and the stress in a measured object and converts the characteristic into digital signal representation. The ultrasonic nondestructive testing technology has relatively strong penetrating power for most media, and the penetrating power can reach several meters in some metal materials. The quantitative measurement of stress in an object to be inspected is of great significance for early prediction of deformation and damage of a member.

When the ultrasonic detection probe detects a detected object, the probe needs to be fixed, so that the probe is prevented from moving, and the measurement error is reduced.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1-8, a probe fixing seat comprises a base 1, wherein the base 1 is provided with two channels 2 for inserting a probe, the channels 2 are obliquely arranged, the bottom of each channel 2 is provided with a matching block 3 for attaching the probe to the surface of a measured object, and the bottom of the base 1 is provided with an adsorption piece 4 for adsorbing the base 1 to the surface of the measured object.

To be more specific, the passage 2 is provided with a leak passage 52 for discharging the couplant on one side. The ultrasonic detection can be performed only by adding the coupling agent, the coupling agent is added into the channel 2 firstly, then the probe is inserted, and the coupling agent is composed of aqueous polymer gel and is in a viscous liquid state. After the couplant is added into the channel 2, the couplant occupies a certain space in the channel 2, if the liquid leakage channel 5 does not exist, the couplant can be accumulated in the channel 2, and when the probe is inserted again, a layer of thick couplant can be separated between the probe and the matching block 3 due to the existence of the couplant, so that the probe cannot be attached to the matching block 3. The detection error is large, the added couplant can be discharged from the liquid leakage channel 5 due to the liquid leakage channel 5, when the probe is inserted into the channel 2, the redundant couplant can be discharged from the liquid leakage channel 5, the couplant is adhered to the channel 2, and the couplant cannot be accumulated in the channel 2. So that the probe can be fitted to the matching block 3. The probe and the channel 2 may be rotatably connected by means of a screw thread.

In further detail, the opening at one end of the leakage channel 5 is positioned on the inner wall of the channel 2 and is just opposite to the surface where the matching block 3 is attached to the probe, and the opening at the other end of the leakage channel 5 is positioned on the outer wall of the base 1. Because the opening of the leakage channel 5 positioned on the inner wall of the channel 2 is over against the joint surface of the matching block 3 and the probe, the couplant can be discharged as much as possible, and the couplant can not be accumulated in the channel 2.

In further detail, the bottom surface of the matching block 3 is flush with the bottom surface of the base 1, and the surface of the matching block 3 attached to the probe is parallel to the cross section of the channel 2. The matching block 3 plays a role of a bridge, the surface of the matching block 3, which is attached to the probe, is parallel to the cross section of the channel 2, so that the end of the probe inserted obliquely can be attached to the matching block 3, the bottom surface of the matching block 3 is flush with the bottom surface of the base 1, and the base 1 is attached to the surface of the measured object. Thereby reducing measurement errors.

In further detail, the base 1 is provided with a groove 6 for the adsorption member 4 to fit into. The groove 6 is used for accommodating the adsorption piece 4, and the adsorption piece 4 can be a magnet. Glue can be added into the groove 6, and the adhesive and adsorption piece 4 is fixed by the glue.

In further detail, the bottom of the base 1 is provided with an arc-shaped groove 7, and the arc-shaped groove 7 is positioned at the corner of the groove 6 and is communicated with the groove 6. The arc-shaped grooves 7 are arranged at four corners of the groove 6 and communicated with the groove 6, so that a certain space is reserved, and the adsorption piece 4 is convenient to install. Meanwhile, the filling amount of the glue is increased, so that the adhesive force is better.

In more detail, the cross section of the arc-shaped groove 7 is in a three-quarter arc shape.

To elaborate further, the base 1 is provided with a chamfer 8 for preventing scratches.

As shown in fig. 1, in the second embodiment, the base 1 is a split joint type. The base 1 can also be the concatenation formula, forms whole base 1 by two single splices, and the concatenation is held each other to accessible absorption piece 4 between two single splices and forms a whole base 1, and two passageways 2 are located two single splices respectively, and to some measured objects that the surface is the cambered surface, two single splices can be placed respectively in the both sides of cambered surface.
