Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic testing technology and relates to an automatic slide rail for ultrasonic testing of weld seams in aluminum alloy thin plates. Background Technology

[0002] In the industrial field, ultrasonic phased array testing technology flexibly generates deflected and focused sound beams by orderly superimposing the sound beams emitted by each array element, enabling high-resolution inspection of areas of interest without changing the probe. Its unique linear scanning, sector scanning, and dynamic focusing modes make the inspection process more efficient, making it particularly suitable for inspecting complex-shaped parts. Furthermore, phased array flaw detectors utilize phased array technology for non-destructive testing, enabling rapid and accurate detection of internal defects in workpieces. In ultrasonic testing of aluminum alloy thin plate welds, it is essential to design an automatic guide rail for ultrasonic testing of aluminum alloy thin plate welds to facilitate the inspection of welds of different sizes and locations. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic slide rail for ultrasonic testing of weld seams in aluminum alloy thin plates.

[0004] The objective of this utility model can be achieved through the following technical solution: An automatic slide rail for ultrasonic testing of weld seams in aluminum alloy thin plates, comprising a slide rail body, characterized in that a through groove is provided in the middle section of the slide rail body, and a mounting frame for mounting an ultrasonic testing device is slidably installed in the through groove. The mounting frame includes a top plate and a pair of base frames. A drive motor is installed at one end of the base frame, which is slidably mounted on the slide rail inside the through groove. The other end of the base frame is connected to the top plate at its top. The top plate has several mounting holes, and an opening for ultrasonic testing is also provided at the center of the top plate. One end of the slide rail body is an extension and connecting part of the through groove, and the other end of the slide rail body is provided with an L-shaped positioning plate for positioning. The L-shaped positioning plate is slidably mounted on the slide rail body and locked by a locking mechanism.

[0005] The working principle of this utility model is as follows: Based on the location of the weld seam in the aluminum alloy sheet to be ultrasonically inspected, the L-shaped positioning plate is pulled out and locked in the designated position using a locking mechanism. Then, the ultrasonic inspection device is installed on the mounting frame through the mounting hole. The ultrasonic inspection device is started, and simultaneously, the mounting frame is controlled by a drive motor to move at a uniform speed along the through groove, achieving automatic inspection. When the weld seam to be inspected is far from the edge of the aluminum alloy sheet, the length of the L-shaped positioning plate is adjusted by pulling it out, thereby reducing unnecessary travel.

[0006] The locking mechanism includes a locking knob and a locking element. The locking knob is threadedly connected to the slide rail body through the threaded part of the rod, and the locking element is fixedly installed on the rod of the locking knob.

[0007] With the above structure, the locking element is pressed against the L-shaped positioning plate by rotating the locking knob, thus achieving locking.

[0008] A buffer pad is installed on the L-shaped positioning plate.

[0009] A second buffer pad is installed at the bottom of the slide rail body.

[0010] By adopting the above structure, the friction between the buffer pad 1 and the buffer pad 2 is increased while playing a buffering role.

[0011] An adapter is provided at the end of the extended connection portion.

[0012] Using the above structure, when the length of the weld to be inspected exceeds the length of the slide rail body, an extension part with the same structure as the through groove extension can be installed through an adapter.

[0013] Compared with existing technologies, the automatic slide rail for ultrasonic testing of aluminum alloy thin plate welds has the following advantages: This utility model, by setting an adjustable length slide rail structure, can effectively test aluminum alloy thin plate welds of different sizes and positions.

A through groove is provided in the middle section of the slide rail body 1. A mounting frame for installing an ultrasonic testing device is slidably installed in the through groove. The mounting frame includes a top plate 2 and a pair of base frames 3. A drive motor 4 is installed at one end of the base frame 3, and the base frame 3 is slidably installed on the slide rail 5 inside the through groove via the drive motor 4. The other end of the base frame 3 is connected to the top plate 2. Several mounting holes 14 are provided on the top plate 2. An opening 6 for ultrasonic testing is also provided at the center of the top plate 2. One end of the slide rail body 1 is an extension and connecting part of the through groove. The other end of the slide rail body 1 is provided with an L-shaped positioning plate 7 for positioning. The L-shaped positioning plate 7 is slidably installed on the slide rail body 1 and locked by a locking mechanism.

[0020] In a specific embodiment, the L-shaped positioning plate 7 is installed in the corresponding storage groove of the slide rail body 1 through the existing sliding sleeve structure, and a limiting device is provided to prevent the L-shaped positioning plate 7 from completely detaching from the slide rail body 1.

[0021] The locking mechanism includes a locking knob 8 and a locking element 9. The locking knob 8 is threadedly connected to the slide rail body 1 via the threaded portion 10 of the rod. The locking element 9 is fixedly installed on the rod of the locking knob 8.

[0022] In this invention, a rubber pad is provided on the contact surface between the locking component 9 and the L-shaped positioning plate 7 to increase friction and enhance the locking effect.

[0023] In a specific embodiment, a servo motor is connected to the locking knob 8 for easy locking, facilitating synchronous control with the ultrasonic testing device.

[0024] A buffer pad 11 is installed on the L-shaped positioning plate 7.
