[0002] Internal defect detection of titanium tubes refers to the process of detecting and evaluating potential internal defects of titanium tubes using various technical means without compromising their performance. The flaw detection device for internal defect detection of titanium tubes is usually used to detect internal defects that may occur during the manufacturing and use of titanium tubes, such as cracks, pores, and inclusions. This device is usually based on some non-destructive testing techniques to ensure the structural integrity of the titanium tubes and that they meet the corresponding quality requirements.

[0003] Currently, while existing titanium tube flaw detection devices can quickly and accurately detect defects, they are inconvenient for marking defective titanium tubes, making it difficult for subsequent workers to distinguish them. This also affects the efficiency of subsequent titanium tube processing, resulting in limited practicality.

[0004] Therefore, those skilled in the art have provided a novel flaw detection device for detecting internal defects in titanium tubes to solve the problems mentioned in the background art. Utility Model Content

[0022] Please see Figure 1-4 A novel flaw detection device for detecting internal defects in titanium tubes includes a support frame 1, with a marking mechanism 2 disposed above the support frame 1.

[0023] The marking mechanism 2 includes a movable frame 201, the outer surface of which is slidably connected to the inner wall of the support frame 1. A servo motor 202 is fixedly connected to the inner wall of the support frame 1. Four support legs 3 are fixedly connected to the bottom surface of the support frame 1. A base 4 is fixedly connected to the bottom surface of each support leg 3. The four support legs 3 can provide a stable support structure for the entire flaw detection device, ensuring that the device will not easily shake when detecting internal defects in titanium tubes, thereby improving the accuracy of detection. The presence of the base 4 can increase the contact area between the support legs 3 and the placement plane, further enhancing stability and preventing the device from tipping over during operation.

[0024] The output end of the servo motor 202 is fixedly connected to a first screw 203. The left end of the first screw 203 is rotatably connected to the inner wall of the support frame 1. The outer surface of the first screw 203 is threadedly connected to the inner wall of the movable frame 201. A protective cover 5 is fixedly connected to the inner wall of the support frame 1. The inner wall of the protective cover 5 is rotatably connected to the outer surface of the first screw 203. The function of the protective cover 5 is to protect the first screw 203 and prevent external factors from damaging the first screw 203, such as preventing dust and debris from entering the connection between the screw and other components. This ensures the normal operation of the first screw 203, thereby ensuring that the movable frame 201 in the marking mechanism 2 can move accurately along the first screw 203 under the drive of the servo motor 202, so as to accurately mark the internal defects of the titanium tube. At the same time, the protective cover 5 is L-shaped and rotatably connected to the first screw 203, which can also further support the first screw 203.

[0025] A fixed frame 204 is fixedly connected to the upper surface of the movable frame 201. Two multi-stage electric telescopic rods 205 are fixedly connected to the inner top wall of the fixed frame 204. A guide column 6 is fixedly connected to the inner wall of the support frame 1. The outer surface of the guide column 6 is slidably connected to the inner wall of the movable frame 201. The guide column 6 can limit the movement direction of the movable frame 201 and prevent the movable frame 201 from deviating or shaking during movement. This helps to improve the movement accuracy of the movable frame 201, so that the marking mechanism 2 fixed on the movable frame 201 can more accurately mark the internal defects of the titanium tube.

[0026] The telescopic ends of the two multi-stage electric telescopic rods 205 are fixedly connected to a lifting plate 206. A fixed cylinder 207 is fixedly connected to the left side of the lifting plate 206. A marker pen 208 is slidably connected to the inner wall of the fixed cylinder 207. A display screen 7 is fixedly connected to the front of the moving frame 201. A warning light 8 is fixedly connected to the upper surface of the moving frame 201. The display screen 7 can be used to display various information related to the flaw detection device, such as the location and size of the detected defects inside the titanium tube, so that the operator can intuitively understand the detection situation. The warning light 8 can issue a warning signal when a defect is detected inside the titanium tube or when the device malfunctions, reminding the operator to pay attention to the detection situation in time, thus improving the safety and ease of operation of the device.

[0027] The inner wall of the fixed cylinder 207 is threaded with two second screws 209. Each second screw 209 has a pressing block 210 rotatably connected to its end near the marker pen 208. The inner wall of the movable frame 201 is fixedly connected with three fixed posts 9. A detection ring 10 is fixedly connected to the outer surface of the three fixed posts 9. The detection ring 10 is fixed to the movable frame 201 by the three fixed posts 9. When the flaw detection device is working, the detection ring 10 can perform inspection operations on the inside of the titanium tube. Due to this fixing method between the detection ring 10 and the movable frame 201, the detection ring 10 can move with the movement of the movable frame 201, thereby inspecting different parts of the titanium tube. The location is used for inspection, ensuring comprehensive internal inspection of the titanium tube. At the same time, the inner wall of the inspection ring 10 integrates multiple ultrasonic flaw detectors and a control system. The ultrasonic flaw detectors utilize the characteristics of ultrasonic waves that propagate at a uniform speed and can be partially reflected on the surface of the tube. The ultrasonic waves emitted by the detector probe are reflected by the inner and outer surfaces of the tube and then received by the probe. By calculating the time difference between the two sets of reflected waves and multiplying it by the ultrasonic wave propagation speed, the actual wall thickness of the tube can be obtained. Internal defects such as cracks, inclusions, and pores can be detected. The detection data is transmitted to the control system, which performs judgment, analysis, and calculation, and simultaneously controls the display screen 7 and the warning light 8.

[0028] The outer surface of each extrusion block 210 is slidably connected to the inner wall of the fixed cylinder 207, and the outer surface of each extrusion block 210 is in contact with the outer surface of the marker pen 208. A reinforcing block 11 is fixedly connected to the right side of the fixed cylinder 207, and the bottom surface of the reinforcing block 11 is fixedly connected to the upper surface of the lifting plate 206. The presence of the reinforcing block 11 can enhance the connection strength between the fixed cylinder 207 and the lifting plate 206. Because during the operation of the marking mechanism 2, the marker pen 208 in the fixed cylinder 207 needs to mark the defects inside the titanium tube, which may be subjected to a certain external force. The reinforcing block 11 can ensure that the fixed cylinder 207 remains stable under such circumstances, and ensure that the marker pen 208 can accurately perform the marking operation.

[0029] The working principle of this utility model is as follows: In use, the operator first connects the power to the servo motor 202, the multi-stage electric telescopic rod 205, the display screen 7, the warning light 8, and the detection ring 10. Then, the titanium tube to be inspected is placed on the surface of the support frame 1. Subsequently, the servo motor 202 and the detection ring 10 are turned on. The servo motor 202 starts, driving the first screw 203 to rotate. Because the inner wall of the moving frame 201 is threadedly connected to the first screw 203, and the outer surface of the moving frame 201 is slidably connected to the inner wall of the support frame 1, the rotation of the first screw 203 causes the moving frame 201 to move within the support frame 1. The movement of the moving frame 201 drives the detection ring 10 to move, thereby enabling flaw detection of the titanium tube. When a defect is detected, further inspection is needed. During marking, the multi-stage electric telescopic rod 205 extends and retracts, driving the lifting plate 206 to move up and down. A marker pen 208 is installed in the fixed cylinder 207 on the lifting plate 206. The marker pen 208 is fixed by two second screws 209 and a pressing block 210 rotatably connected to the second screws 209. When the marker pen 208 needs to perform a marking action, it reaches a suitable height position with the cooperation of the multi-stage electric telescopic rod 205 and other structures. Then, the servo motor 202 can drive the marker pen 208 to move, thereby drawing a marking line on the surface of the titanium tube for marking, which is convenient for subsequent workers to distinguish. The moving frame 201 has a display screen 7 on the front, which can display relevant inspection information. The warning light 8 on the upper surface can issue a warning when a defect is detected.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
