Description

Technical Field

[0001] The utility model relates to the technical field of probes, and in particular to a TOFD nondestructive testing probe which is easy to install quickly. Background Art

[0002] TOFD nondestructive testing probe generally refers to the probe used for TOFD nondestructive testing technology. TOFD nondestructive testing is a commonly used nondestructive testing technology, which is used to detect surface and near-surface defects of materials or workpieces. The probe is an important tool in this technology for approaching the object to be tested and performing testing operations. The TOFD nondestructive testing probe is generally composed of one or more sensors, which are used to receive and convert ultrasonic signals reflected from the object to be tested. The design and material of the probe may vary according to the object to be tested and the testing requirements. In the process of nondestructive testing, the installation time of the existing TOFD nondestructive testing probe is an important factor. If the installation speed is slow, the preparation time before testing will be extended, thereby reducing the overall testing efficiency. Therefore, we propose a TOFD nondestructive testing probe that is easy to install quickly, so as to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the installation time of the existing TOFD nondestructive testing probe is an important factor in the nondestructive testing process, if the installation speed is slow, the preparation time before testing will be extended, thereby reducing the overall testing efficiency.

[0004] The technical solution of the utility model is: a TOFD non-destructive testing probe that is easy to install quickly, including an installation module, a sliding module, a clamping module and a connecting module; a sliding module that can slide and drive the connecting module to move horizontally to expand the detection area is provided below the installation module, a connecting module for non-destructive testing is installed at the lower end of the sliding module, and the outer sleeve of the connecting module is provided with a clamping module that is used to drive the connecting module and the sliding module to be quickly installed and is positioned and connected with the sliding module.

[0005] Preferably, the U-shaped frame is first fixedly connected to the wall by means of expansion screws passing through the mounting holes, and then the probe body is quickly installed. By pulling the L-shaped pull rod, the spring is forced to contract, and the partition moves laterally outward along the rectangular groove and the strip groove, so that the L-shaped clip frame can drive the annular connecting plate to be positioned and connected with the square connecting plate through the rectangular groove, thereby preventing the probe body from falling off during operation. The L-shaped pull rod is then released, and the spring rebounds, and the partition moves laterally inward along the rectangular groove and the strip groove to fix the L-shaped clip frame. At the same time, the mounting ring sleeve is fixedly clamped with the square connecting plate through the circular mounting groove, thereby achieving a quick installation effect.

[0006] Preferably, the mounting module includes a U-shaped frame and a slide rail, the U-shaped frame is installed on the upper end of the slide rail, a plurality of mounting holes for expansion screws to pass through are arranged in an array on the U-shaped frame, a T-shaped slot for the sliding module to slide is arranged at the bottom of the slide rail, the U-shaped frame is fixedly connected to the wall by means of expansion screws passing through the mounting holes, thereby improving the stability of the TOFD nondestructive testing probe.

The L-shaped snap-in frame drives the annular connecting plate to be positioned and connected with the square connecting plate through a rectangular groove to prevent the probe body from falling off during operation.

[0011] Preferably, the connecting module includes a mounting ring sleeve, an L-shaped rotating shaft, a connecting column and a probe body. The mounting ring sleeve is fixedly connected to the square connecting plate through a circular mounting groove. The interior of the mounting ring sleeve is provided with an L-shaped rotating shaft.

If the installation speed is slow, the preparation time before the test will be extended, thereby reducing the overall testing efficiency. The difference is that the U-shaped frame is first fixedly connected to the wall through the installation hole by the expansion screw, and then the probe body is quickly installed. By pulling the L-shaped pull rod, the spring is forced to shrink, and the partition moves laterally outward along the rectangular groove and the strip groove, which is convenient for the L-shaped clamping frame to drive the annular connecting plate to be positioned and connected with the square connecting plate through the rectangular groove to prevent the probe body from falling off during operation. Then the L-shaped pull rod is released, the spring rebounds, and the partition moves laterally inward along the rectangular groove and the strip groove to fix the L-shaped clamping frame. At the same time, the mounting ring is fixedly clamped with the square connecting plate through the circular mounting groove, thereby achieving the effect of quick installation.

[0014] 2. Driven by the driver, the T-shaped slider drives the square connecting plate to slide along the T-shaped slot and connect with the slide rail, thereby expanding the detection area of ​​the probe body. Then, when the probe body is running, the L-shaped rotating shaft drives the probe body to rotate along the mounting ring sleeve through the driver, thereby expanding the detection range of the probe body. In this process, the connecting column firmly supports the probe body to prevent the probe body from tilting. BRIEF DESCRIPTION OF THE DRAWINGS
