Description

Technical Field

[0001] This utility model belongs to the technical field of test blocks, specifically a test block for pipe seat fillet welds. Background Technology

[0002] Ultrasonic testing blocks are artificial reflective specimens with simple geometric shapes designed and manufactured for specific purposes. They serve to determine the sensitivity of the test, the performance of the instrument and probe, adjust the scanning speed, and assess the size of defects. When inspecting fillet welds on pipe seats, the length of existing test blocks cannot be adjusted according to the testing conditions. Furthermore, the current test blocks are installed on the ultrasonic testing equipment, making them inconvenient to replace and limiting their practicality. Additionally, for some small-diameter pipe seats, test blocks used for adjusting the scanning time only have a curved surface at one end, which can be used for adjusting the upper surface probe, but the lower surface probe cannot be adjusted simultaneously. If adjustment is required, additional test blocks must be fabricated to calibrate the equipment, making the operation very cumbersome. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a test block for fillet welds of pipe seats, which has the advantage of being more practical.

[0004] The objective of this utility model can be achieved through the following technical solution: A test block for pipe seat fillet welds includes an adjustment box, a first test block located at one end of the adjustment box, and a second test block located at the other end of the adjustment box. The adjustment box has symmetrically opened first grooves on both sides. Each first groove has a first guide rail symmetrically installed on the upper and lower sides of its inner wall and a second guide rail symmetrically installed on the left and right sides. The adjustment box has symmetrically opened first through holes on both sides. The upper and lower surfaces of the first test block and the second test block have a plurality of second through holes arranged thereon. The first test block and the second test block have a sliding seat near the inner wall of the first groove. The sliding seat slides in cooperation with the first guide rail and the second guide rail.

[0005] It also includes a fixing member, which passes through the first through hole of the adjustment box and is threaded into the second through hole of the first test block or the second through hole of the second test block for fixation.

[0006] Preferably, the first test block and the second test block are arranged in opposite directions and orientations.

[0007] Preferably, a limiting groove is provided at the bottom of the first groove near the adjustment box of the sliding seat, and a limiting part is provided at the bottom of the first groove of the adjustment box, and the limiting part engages with the limiting groove for limiting.

[0008] Preferably, the surface of the limiting portion facing the limiting groove has a sealing gasket.

[0009] Preferably, the upper and lower surfaces of the sliding seat are provided with a first sliding groove, and the first guide rail is provided with a first sliding part, which slides in cooperation with the first sliding groove.

[0010] Preferably, the sliding seat has a second sliding groove on both the left and right surfaces, and the second guide rail has a second sliding part that slides in conjunction with the second sliding groove.

[0011] Compared with the prior art, the advantages of this utility model are: by adding a first guide rail and a second guide rail to drive the first test block or the second test block to move inward or outward, it can adjust its length according to the testing situation, without the need to replace the test block with a new specification, thus improving the testing adaptability and practicality. At the same time, with two test blocks, the upper and lower surface probes can be adjusted simultaneously, saving testing time and further enhancing practicality. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 4As shown, a test block for inspecting fillet welds of pipe seats is characterized by comprising an adjustment box 2, a first test block 3 located at one end of the adjustment box 2, and a second test block 4 located at the other end of the adjustment box 2. The adjustment box 2 has symmetrically opened first grooves 21 on both sides. Each first groove 21 has a first guide rail 22 symmetrically installed on the upper and lower sides of its inner wall and a second guide rail 23 symmetrically installed on the left and right sides. The adjustment box 2 also has symmetrically opened first through holes 24 on both sides. The upper and lower surfaces of the first test block 3 and the second test block 4 are provided with a plurality of second through holes 25. The first test block 3 and the second test block 4 have a sliding seat 41 near the inner wall of the first groove 21. The sliding seat 41 is slidably engaged with the first guide rail 22 and the second guide rail 23.

[0019] It also includes a fixing member 5, which passes through the first through hole 24 of the adjustment box 2 and is threadedly connected to the second through hole 25 of the first test block 3 or the second through hole 25 of the second test block 4 for fixation.

[0020] By adopting the above structure, the addition of the first guide rail 22 and the second guide rail 23 drives the first test block 3 or the second test block 4 to move inward or outward, allowing for length adjustment according to the testing situation. This eliminates the need to replace with new test blocks of different specifications, resulting in better testing adaptability and practicality. Simultaneously, it is fixed by a fixing member 5, which is a bolt. The bolt passes through the first through hole 24 of the adjusting box 2 and is threaded into the second through hole 25 of either the first test block 3 or the second test block 4. This helps prevent the first and second test blocks 3 and 4 from loosening or shifting during testing. The structure is simple and the fixation is reliable. The presence of two test blocks allows for simultaneous adjustment of the upper and lower surface probes, saving testing time and further enhancing practicality.

[0021] Specifically, such as Figures 1 to 4 As shown, the first test block 3 and the second test block 4 are arranged in opposite directions and orientations.

[0022] By adopting the above structure, and by setting two test blocks simultaneously with opposite orientations for the test ports, the upper and lower surface probes can be adjusted at the same time, saving testing time and making it more practical.

[0023] like Figures 1 to 4As shown, a limiting groove 61 is formed at the bottom of the first groove 21 near the adjustment box 2 on the sliding seat 41. A limiting part 62 is provided at the bottom of the first groove 21 of the adjustment box 2. The limiting part 62 engages with the limiting groove 61 for limiting. By engaging the limiting part 62 with the limiting groove 61 for limiting, when the device is not in use, both the first test block 3 and the second test block 4 can be retracted and moved into the first groove 21 and stored by the engaging limiting method, which helps to reduce the size of the device and save placement space.

[0024] like Figures 1 to 4 As shown, the surface of the limiting part 62 facing the limiting groove 61 has a sealing gasket 63. By providing the sealing gasket 63, it is beneficial to achieve better snap-fit ​​limiting.

[0025] like Figures 1 to 4 As shown, the upper and lower surfaces of the sliding seat 41 each have a first sliding groove 71, and the first guide rail 22 has a first sliding part 72, which slides in conjunction with the first sliding groove 71. The left and right surfaces of the sliding seat 41 each have a second sliding groove 73, and the second guide rail 23 has a second sliding part 74, which slides in conjunction with the second sliding groove 73. The sliding engagement of the first sliding part 72 with the first sliding groove 71 and the second sliding part 74 with the second sliding groove 73 facilitates the movement of the first test block 3 or the second test block 4. Furthermore, the presence of a first sliding groove 71 or a second sliding groove 73 on each surface helps prevent displacement during movement.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
