Description

Technical Field

[0001] This utility model relates to the field of steel furniture processing technology, specifically to a positioning frame for non-destructive testing of weld seams in steel furniture. Background Technology

[0002] In the manufacturing process of steel furniture, such as cabinets, the cut steel plate blanks are usually folded to form a single-sided open compartment. The two sides and the top and bottom of the compartment are then bent towards the center to form an enclosure, and four identical gaps are formed at the joint of the enclosure. These four gaps are then welded together to form a sealed connection.

[0003] After welding is completed, non-destructive testing is usually performed using an ultrasonic flaw detector. In the traditional testing process, the inspector usually moves the probe along the weld by hand and uses the waveform feedback of the ultrasonic waves to determine whether there are hidden defects in the weld. However, in this process, it is impossible to ensure that the distance between the probe and the weld is constant when moving the probe by hand. At the same time, the probe needs to be properly placed after the test to avoid damage. This makes the entire testing operation greatly affected by human factors. Therefore, a positioning frame for non-destructive testing of welds in steel furniture is specially provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning frame for non-destructive testing of weld seams in steel furniture. This solves the problem that when conducting weld seam testing on steel furniture, the handheld probe cannot maintain a constant distance from the weld seam during movement, and the probe needs to be properly placed after testing to avoid damage. This makes the entire testing operation highly susceptible to human error.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning frame for non-destructive testing of weld seams in steel furniture, including a rotating carrier and a probe bracket;

[0006] The rotating carrier includes a fixed platform and a rotating carrier plate rotatably disposed on the top of the fixed platform for fixing steel furniture.

[0007] The probe bracket includes a vertical positioning rail and a sliding seat slidably mounted on the vertical positioning rail. A probe fixing arm is rotatably mounted at the end of the sliding seat. A positioning support part is integrally formed on the lower surface of the end of the sliding seat. The positioning support part abuts against the bottom of the probe fixing arm and is used to provide horizontal support for the probe fixing arm.

[0008] Preferably, clamping plates are movably provided on both sides of the top of the rotating carrier plate, and the two sets of clamping plates are used to centrally clamp the steel furniture.

[0009] Preferably, the rotating carrier plate has a sliding groove, and a bidirectional lead screw is rotatably connected in the sliding groove. The two sets of clamping plates are respectively threaded to both ends of the bidirectional lead screw, so that the two sets of clamping plates can move synchronously towards or away from each other along the sliding groove.

[0010] Preferably, the bottom end of the vertical positioning rail is fixedly assembled with the fixed platform, and a fixing strip is fixedly installed on the top of the vertical positioning rail.

[0011] Preferably, a rubber sleeve is fixedly provided in the sliding seat, and the vertical positioning rail moves through the rubber sleeve. The friction between the rubber sleeve and the vertical positioning rail allows the sliding seat to stay at any position on the outer wall of the vertical positioning rail.

[0012] Preferably, the probe fixing arm has an extension rod movably disposed inside, and the end of the extension rod is fixedly welded to a probe assembly part.

[0013] Preferably, the probe assembly is threaded with a fixing bolt for fixing the ultrasonic probe, and the end of the probe fixing arm is threaded with a locking bolt for fixing the extension rod.

[0014] Preferably, the outer wall of the sliding seat is integrally formed with a handle.

[0015] This utility model discloses a positioning frame for non-destructive testing of weld seams in steel furniture. Its beneficial effects are as follows: The welded cabinet is placed on top of a rotating carrier plate and clamped in the center by two sets of clamping plates. An ultrasonic probe is inserted into the probe assembly part, and the extension rod is pulled outwards to bring the probe closer to one side of the weld. The handle is moved up and down along the vertical positioning rail, causing the ultrasonic probe to move vertically up and down along one side of the weld seam for testing. Then, the probe fixing arm is rotated 180 degrees at the end of the sliding seat to test the weld seam on the other side. The cabinet end is then rotated to change its orientation for testing the other two sets of weld seams. Throughout the process, the ultrasonic probe does not need to be held by hand; the vertical positioning rail and probe fixing arm provide support and positioning, ensuring a constant distance between the ultrasonic probe and the weld seam during testing. Furthermore, it allows for quick adjustment when testing multiple weld seams, facilitating operation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a positioning frame for non-destructive testing of weld seams in steel furniture, which solves the problem that existing steel furniture weld seam testing methods cannot guarantee a constant distance between the handheld probe and the weld seam during movement, and the probe needs to be properly placed after testing to avoid damage. This makes the entire testing operation highly susceptible to human error.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a positioning frame for non-destructive testing of weld seams in steel furniture, according to the attached... Figure 1-3 As shown, it includes a rotating carrier 1 and a probe bracket 2;

[0025] The rotating carrier 1 includes a fixed platform 11 and a rotating carrier plate 12 rotatably disposed on the top of the fixed platform 11 for fixing steel furniture;

[0026] The probe bracket 2 includes a vertical positioning rail 21 and a sliding seat 22 slidably mounted on the vertical positioning rail 21. A probe fixing arm 24 is rotatably mounted at the end of the sliding seat 22. A positioning support part 29 is integrally formed on the lower surface of the end of the sliding seat 22. The positioning support part 29 abuts against the bottom of the probe fixing arm 24 and is used to provide horizontal support for the probe fixing arm 24.

[0027] Clamping plates 14 are movably installed on both sides of the top of the rotating carrier plate 12. The two sets of clamping plates 14 are used to clamp the steel furniture in the center. A sliding groove 13 is opened in the rotating carrier plate 12. A two-way screw rod 15 is rotatably connected in the sliding groove 13. The two sets of clamping plates 14 are respectively threaded to both ends of the two-way screw rod 15, so that the two sets of clamping plates 14 can move synchronously towards or away from each other along the sliding groove 13, thereby achieving the centering clamping of the cabinet.

[0028] The bottom end of the vertical positioning rail 21 is fixedly assembled with the fixed platform 11, and the top of the vertical positioning rail 21 is fixedly installed with a fixing strip 23. The vertical positioning rail 21 is located on the midline between the two sets of clamping plates 14, so that the sliding seat 22 can be located in the middle of the end of the cabinet when in use.

[0029] A rubber sleeve 210 is fixedly installed in the sliding seat 22. The vertical positioning rail 21 moves through the rubber sleeve 210. The friction between the rubber sleeve 210 and the vertical positioning rail 21 allows the sliding seat 22 to stop at any position on the outer wall of the vertical positioning rail 21. The friction between the rubber sleeve 210 and the vertical positioning rail 21 can overcome the overall weight of the sliding seat 22, thus achieving the effect of stopping at will and making it convenient to use.

[0030] An extension rod 25 is movably installed inside the probe fixing arm 24. A probe assembly part 26 is fixedly welded to the end of the extension rod 25. A fixing bolt 28 for fixing the ultrasonic probe is threaded in the probe assembly part 26. A locking bolt 27 for fixing the extension rod 25 is threaded in the end of the probe fixing arm 24. The extension rod 25 can be extended and retracted at the end of the probe fixing arm 24 to adapt to cabinets of different widths.

[0031] The outer wall of the sliding seat 22 is integrally formed with a handle 211. The sliding seat 22 is moved up and down along the vertical positioning rail 21 by means of the handle 211 to ensure that the movement is vertical and does not deviate.

[0032] Working principle: When using this device, the welded cabinet is placed on top of the rotating carrier plate 12 with the back of the cabinet facing down and the top facing the vertical positioning rail 21. The cabinet is then pushed towards the vertical positioning rail 21 to bring it close to the probe assembly part 26. Then, the bidirectional lead screw 15 is rotated so that the two sets of clamping plates 14 move along the slide groove 13 towards the center to clamp the cabinet in the center.

[0033] Then, insert the ultrasonic probe into the probe assembly part 26, and tighten the fixing bolt 28. At this time, pull the extension rod 25 outward so that the probe is close to the weld seam on the cabinet side. Then tighten the locking bolt 27. At this time, start the ultrasonic flaw detector, and then move the handle 211 up and down along the vertical positioning rail 21 so that the ultrasonic probe moves vertically up and down along one side of the weld seam to inspect a set of weld seams. Then, rotate the probe fixing arm 24 180 degrees at the end of the sliding seat 22, and keep the probe fixing arm 24 horizontal through the positioning support part 29. At this time, inspect the weld seam on the other side through the ultrasonic probe.

[0034] After the weld seams on both sides are inspected, loosen the double-ended screw 15, then rotate the carrier plate 12 so that the bottom of the cabinet faces the vertical positioning rail 21. Then move the cabinet close to the ultrasonic probe, and then tighten the double-ended screw 15. Repeat the above steps to inspect the weld seams on both sides of the bottom of the cabinet.

[0035] Throughout the process, there is no need to hold the ultrasonic probe. The vertical positioning rail 21 and the probe fixing arm 24 are used for support, positioning and movement, ensuring that the ultrasonic probe can maintain a constant distance from the weld during the test. At the same time, it can be quickly adjusted when testing multiple welds, making it convenient to operate.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
