Technical Field

[0001] The utility model relates to the field of welding detection, in particular to a rolling weld crack scanner. Background Art

[0002] Welding is an important processing technology in the mechanical processing process. After welding, the workpiece needs to be tested for welding quality. To ensure the quality of the inspection, construction personnel usually use weld ultrasonic detectors to inspect the welds of the workpiece to be tested, so as to find defects inside the welds and prevent the appearance of defective products.

[0003] When inspecting the end face welds of tubular welded parts, the currently used weld ultrasonic detectors often rely on manual holding to move the weld ultrasonic detectors, which places high demands on manpower. Utility Model Content

[0004] The utility model aims to provide a rolling weld crack scanner, which solves the problem that the existing weld ultrasonic detector often relies on manual holding to move the weld ultrasonic detector when detecting the end weld of a tubular welded component, which has high manpower requirements.

[0005] To achieve the above-mentioned purpose, the utility model provides a rolling weld crack scanner, which is clamped and fixed on a tubular part, including a detection plate, one side of which is equipped with a display, a group of clamping plates are respectively installed on both sides of the detection plate, and two groups of the clamping plates are equipped with driving plates close to the detection plate. The two groups of driving plates are slidably inserted into the detection plate and driven by the driving structure in the detection plate to move in a mirror image. The close sides of the two groups of clamping plates are fixed with clamping arc plates, and multiple groups of clamping rollers and scanners are rotatably installed in the clamping arc plates. The clamping rollers are used to clamp and press on the side of the tubular part when the two groups of clamping plates are close in mirror image. The scanner is used to perform ultrasonic scanning on the weld on the tubular part and send the scanning information to the display for display. The driving structure includes a driving gear and two groups of transmission racks. The driving gear is rotatably installed in the detection plate through a mounting shaft. The two groups of transmission racks are fixedly connected to the corresponding driving plates and meshedly connected to the two sides of the driving gear. The mounting shaft of the driving gear is driven to rotate by a power member.

[0006] As a further solution of the utility model, a guide channel for sliding connection between two sets of driving plates is provided in the detection plate.

[0007] As a further solution of the utility model, the driving structure is a driving worm, which is rotatably installed on the top of the detection plate. The installation shaft of the driving gear extends out of the detection plate, and a transmission worm wheel meshing with the driving worm is coaxially fixed thereon.

[0008] As a further solution of the utility model, a protective cover is provided on the outer side of the driving worm.

[0009] As a further solution of the utility model, two groups of clamping rollers are rotatably mounted on the clamping arc plate, the two groups of clamping rollers are rotatably connected to both ends of the clamping arc plate, and the scanner is fixedly mounted in the middle of the clamping arc plate.

[0010] Compared with the prior art, the utility model designs a detection plate and installs a display, a clamping plate and a clamping arc plate on the detection plate. The clamping roller in the clamping arc plate is pressed against the side of the tubular part to realize the clamping function. The detection plate can be manually controlled to rotate around the tubular part, so that the scanner can scan and detect the weld. The scanned image can be transmitted to the display for personnel to view, thereby solving the problem that the existing weld ultrasonic detector often relies on manual holding of the weld ultrasonic detector to move when detecting the end face weld of the tubular welding component, which has high manpower requirements.

The driving plates 4 are slidably inserted into the detection plate 7 and driven by the driving structure in the detection plate 7. The near side of the two groups of the clamping plates 3 is fixed with a clamping arc plate 2, and multiple groups of clamping rollers 5 and a scanner 6 are rotatably installed in the clamping arc plate 2. The clamping roller 5 is used to clamp and press the side of the tubular member 1 when the two sets of clamping plates 3 are mirror-imaged and close to each other. The scanner 6 is used to perform ultrasonic scanning on the weld 101 on the tubular member 1 and send the scanning information to the display 9 for display. The driving structure includes a driving gear 10 and two sets of transmission racks 12. The driving gear 10 is rotatably mounted in the detection plate 7 through a mounting shaft 11. The two sets of transmission racks 12 are fixedly connected to the corresponding driving plates 4 and meshedly connected to both sides of the driving gear 10. The mounting shaft 11 of the driving gear 10 is driven to rotate by a power member.

[0018] Specifically, when the utility model is in use, the drive structure can be operated to drive the two groups of clamping plates 3 to move closer in a mirror-like manner, so that the clamping rollers 5 in the two groups of clamping arc plates 2 are pressed against the side of the tubular member 1 to achieve the clamping function. At this time, the scanner 6 on the clamping arc plate 2 is aligned with the weld 101 on the tubular member 1. At this time, the detection plate 7 can be manually controlled to rotate around the tubular member 1, so that the scanner 6 can scan and detect the weld 101, and the scanned image can be transmitted to the display 9 for personnel to view.

[0019] like Figures 1 to 4 As shown, in the embodiment of the utility model, the detection plate 7 is provided with a guide channel for sliding connection of two sets of driving plates 4;

[0020] Further, the driving structure is a driving worm 13, which is rotatably mounted on the top of the detection plate 7, and the mounting shaft 11 of the driving gear 10 extends out of the detection plate 7, on which a transmission worm wheel 14 meshingly connected with the driving worm 13 is coaxially fixed. When the clamping plate 3 and the driving plate 4 are moved, the driving worm 13 can be rotated to mesh and drive the transmission worm wheel 14 and the coaxially connected driving gear 10 to rotate, and the driving gear 10 is meshed and driven by the two sets of transmission racks 12, so as to drive the corresponding driving plate 4 and the clamping plate 3 to move in a mirror image;

[0021] Of course, the driving structure of the mounting shaft 11 actually used to drive the driving gear 10 can also be preferably a stepping motor, and the stepping motor drives the mounting shaft 11 and the driving gear 10 to rotate to achieve the driving operation;

[0022] Furthermore, a protective cover 8 is provided on the outer side of the driving worm 13 , and the protective cover 8 is used to protect the driving worm 13 and the transmission worm wheel 14 .

The scanner 6 is fixedly mounted in the middle of the clamping arc plate 2, and ultrasonic scanning of the weld 101 can be performed.

[0024] In summary, the utility model designs a detection plate 7, and installs a display 9, a clamping plate 3 and a clamping arc plate 2 on the detection plate 7. The clamping roller 5 in the clamping arc plate 2 is pressed against the side of the tubular member 1 to realize the clamping function. The detection plate 7 can be manually controlled to rotate around the tubular member 1, so that the scanner 6 can scan and detect the weld 101. The scanned image can be transmitted to the display 9 for personnel to view, thereby solving the problem that the existing weld 101 ultrasonic detector often relies on manual holding of the weld 101 ultrasonic detector to move when detecting the end face weld 101 of the tubular welding component, which has high manpower requirements.
