Description

Technical Field

[0001] The utility model relates to a wedge block water storage type immersion ultrasonic testing device, belonging to the technical field of ultrasonic testing. Background Art

[0002] In the technology of detecting steel cylinders by the immersion method, the commonly used detection method at present is to detect by the upper detection method, that is, the water column valve. However, when using this method, cavities are likely to appear inside, resulting in problems with the transmission of detection sound waves. Therefore, those skilled in the art have been researching methods to solve this problem. Content of the Utility Model

[0003] In order to solve the problem that cavities are likely to appear in the ultrasonic detection by the upper column method, resulting in problems with the transmission of detection sound waves, this application designs a wedge block for ultrasonic detection with a probe preferably arranged below, that is, a wedge block water storage type immersion ultrasonic testing device.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A wedge block water storage type immersion ultrasonic testing device includes a wedge block housing. The wedge block housing has a water storage inner cavity. A probe mounting groove is provided at the bottom of the water storage inner cavity. The probe mounting groove can move horizontally at the bottom of the water storage inner cavity. A probe is mounted in the probe mounting groove. Water inlet holes are provided on both sides of the probe mounting groove. Fixed grooves are provided on both sides of the wedge block housing. The detection side of the wedge block housing is set as the bottom of the wedge block with an arc-shaped concave surface.

[0006] On the basis of the above technical solutions, this application makes the following improvements and refinements to the above technical solutions:

[0007] Further, soft foam structures are installed around the bottom of the wedge block.

[0008] Further, T-shaped mounting grooves are provided around the bottom of the wedge block.

[0009] Further, the bottom of the water storage inner cavity of the wedge block housing is set as a bottom plate with a movable connection.

[0010] Further, a sealing gasket is provided between the bottom plate and the side wall of the wedge block housing.

[0011] Further, a connecting pipe is provided at the water inlet hole.

[0012] Further, the probe mounting groove can move up and down at the bottom of the water storage inner cavity, so as to control the distance between the front end of the probe and the workpiece to be detected.

[0013] The advantages of the above technical solution are as follows: Water is injected into the water storage cavity through the water inlet hole. The gas cylinder workpiece to be detected is placed against the arc-shaped groove at the bottom of the wedge block. The probe uses a linear array phased water immersion probe to detect the gas cylinder. The bottom of the wedge block is designed in an arc shape, which can be the same size as the workpiece to be detected, better fit, and a soft foam structure is arranged around it to reduce excessive water overflow and irregular fitting of the workpiece to be detected. Description of the Drawings

[0014] Figure 1 It is a schematic three-dimensional structure diagram of a wedge block water storage type water immersion ultrasonic testing device;

[0015] Figure 2 is Figure 1 the bottom structure diagram of.

[0016] Among them, each part is respectively: 1 - probe, 2 - water inlet hole, 3 - fixed groove, 4 - wedge block housing, 5 - bottom of the wedge block, 6 - bottom plate, 7 - sealing gasket, 8 - soft foam structure. Specific Embodiments

[0017] The following embodiments in conjunction with the drawings are only to illustrate the technical solutions recorded in the claims, and are not intended to limit the scope of protection of the claims.

[0018] A wedge block water storage type water immersion ultrasonic testing device, as Figure 1 、 2 shown, includes a wedge block housing 4. The wedge block housing 4 has a water storage inner cavity. A probe mounting groove is provided at the bottom of the water storage inner cavity. The probe mounting groove moves up and down at the bottom of the water storage inner cavity through a motor arranged inside. The probe 1 is installed in the probe mounting groove. Water inlet holes 2 are provided on both sides of the probe mounting groove. Connecting pipes are provided on the water inlet holes 2. Fixed grooves 3 are provided on both sides of the wedge block housing 4. The detection side of the wedge block housing 4 is set as the wedge block bottom 5 with an arc-shaped concave surface. Soft foam structures 8 are installed around the wedge block bottom 5. T-shaped mounting grooves are provided around the wedge block bottom 5. The bottom of the water storage inner cavity of the wedge block housing 4 is set as a movably connected bottom plate 6. A sealing gasket 7 is provided between the bottom plate 6 and the side wall of the wedge block housing 4.

[0019] The usage method of the above wedge block water storage type water immersion ultrasonic testing device is as follows. The tooling probe fixture clamps the wedge block through the fixed groove 3 and is placed at the bottom of the water tank. The wedge block bottom 5 faces up and contacts the workpiece gas cylinder to be detected. Water is injected into the wedge block through the gold water inlet hole 2. The workpiece to be detected rotates automatically for inspection. Control the thickness of the water layer and detect the gas cylinder through the linear array probe.

[0020] The advantages of this method are: environmental protection and water saving. It does not require a large amount of water to be injected in advance, nor does it require a large water tank for water immersion testing. A very small tool that can collect water at the bottom is sufficient.

[0021] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
