Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic flaw detection technology, and in particular to an automatic ultrasonic flaw detection device for rolled tube blanks. Background Technology
[0002] During the production of metal pipes, defects such as cracks, pores, and inclusions may exist inside the rolled tube blank, which seriously affect the mechanical properties and safety of the finished pipe. Therefore, non-destructive testing must be carried out before forming. Ultrasonic testing has become the mainstream technology for detecting internal defects in tube blanks due to its strong penetration and high sensitivity.
[0003] Existing flaw detection systems mostly use fixed probes, which are positioned in a fixed position and can only be used to inspect tube blanks of a single specification. When tube blanks of different diameters are replaced, the acoustic coupling distance between the probe and the tube wall changes, resulting in signal attenuation or distortion, which affects the detection accuracy. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic ultrasonic flaw detection device for rolled tube blanks includes: Mounting base; The movable component is slidably connected to the inner cavity of the mounting base via a slide rail. One end of the movable component passes through the through groove of the mounting base, and a mounting component is slidably disposed at the end of the movable component. The threaded rod is rotatably mounted on the mounting component, and the threaded rod is installed by engaging with the threaded hole on the moving component. The power motor is mounted on the mounting bracket, and the threaded rod is connected to the output end of the power motor. The ultrasonic probe is mounted on the mounting component via a connecting mechanism. The support mechanism is installed at the end of the mounting base and is used to support the tube blank.

Two auxiliary components are slidably mounted on both ends of the mounting base along the length direction via guide rails. Bolts are provided on the auxiliary components, and connecting shafts are also rotatably mounted on the two auxiliary components. At least two support rollers that slide along the length direction are provided on the connecting shaft, and screws are provided on the support rollers.

[0018] This application provides an automatic ultrasonic flaw detection device for rolled tube blanks, comprising: Mounting base 1; The movable part 2 is slidably connected to the inner cavity of the mounting base 1 via a slide rail. One end of the movable part 2 passes through the through groove of the mounting base 1, and the mounting part 3 is slidably provided at the end of the movable part 2. The threaded rod 4 is rotatably mounted on the mounting part 3, and the threaded rod 4 is installed in conjunction with the threaded hole on the movable part 2. The power motor 5 is mounted on the mounting part 3, and the threaded rod 4 is connected to the output end of the power motor 5. The ultrasonic probe 6 is mounted on the mounting component 3 via the connecting mechanism 7; Support mechanism 8 is installed at the end of mounting base 1 and is used to support the tube blank; The power mechanism 9 is installed on the mounting base 1. The power mechanism 9 provides displacement power to the ultrasonic probe 6 and rotational power to the support mechanism 8. Through the technical solution of this utility model, the mounting base 1 serves as the bearing foundation. The moving part 2, in conjunction with the displacement power provided by the power mechanism 9, drives the mounting part 3 and the ultrasonic probe 6 to move along the length of the tube blank, achieving full-length flaw detection coverage of the tube blank and improving the detection range. The threaded rod 4 rotatably mounted on the mounting part 3 engages with the threaded hole of the moving part 2, and the threaded rod 4 is driven to rotate by the power motor 5. Starting the power motor 5 adjusts the height of the mounting part 3, thereby adjusting the relative distance between the ultrasonic probe 6 and the tube blank, adapting to rolled tube blanks of different diameters and improving the versatility of the device. The support mechanism 8 is installed at the end of the mounting base 1, providing support for the rolled tube blank. In conjunction with the rotational power provided by the power mechanism 9, it drives the tube blank to rotate smoothly, enabling the ultrasonic probe 6 to perform comprehensive circumferential detection of the tube blank, eliminating blind spots. The power mechanism 9 simultaneously provides power for the displacement of the ultrasonic probe 6 and the rotation of the support mechanism 8, reducing manual labor intensity and ensuring continuous and efficient flaw detection.
[0019] During use, the support mechanism 8 includes: Two fasteners 81 are respectively installed at both ends of the mounting base 1 along its length, and a connecting shaft 82 is rotatably mounted on the fasteners 81; Two auxiliary components 83 are slidably mounted on both ends of the mounting base 1 along the length direction via guide rails. Bolts 84 are provided on the auxiliary components 83, and connecting shafts 82 are also rotatably mounted on the two auxiliary components 83. At least two support rollers 86 that slide along the length direction are provided on the connecting shaft 82, and screws 85 are provided on the support rollers 86; Through the technical solution of this utility model, the two fixing parts 81 provide a supporting foundation for the connecting shaft 82. The bolts 84 on the auxiliary part 83 are locked after the auxiliary part 83 slides to the target position. The distance between the connecting shaft 82 on the auxiliary part 83 and the connecting shaft 82 on the fixing part 81 is adjusted by sliding the auxiliary part 83 to adapt to rolled tube blanks of different diameters. The sliding support roller 86 adjusts the distance between the two support rollers 86 to adapt to rolled tube blanks of different lengths, avoiding wobbling due to insufficient support points for the tube blank. The support roller 86 rotates synchronously with the connecting shaft 82, driving the tube blank to rotate, and realizing comprehensive inspection of the circumference of the tube blank.

Through the technical solution of this utility model, the servo motor 93 provides stable power output, driving the lead screw 91 to rotate. The guide member 92 cooperates with the lead screw 91 through the threaded inner hole, accurately converting the rotational motion of the servo motor 93 into the linear motion of the guide member 92, thereby driving the ultrasonic probe 6 to move along the length of the tube blank, ensuring that the probe covers the entire length of the tube blank for flaw detection. The transmission mechanism 94 is connected to the lead screw 91 and the connecting shaft 82 installed on the fixing member 81, respectively, and synchronously transmits the rotational power of the lead screw 91 to the connecting shaft 82, driving the connecting shaft 82 of the support mechanism 8 and the tube blank to rotate smoothly, realizing the coordinated linkage between the length direction displacement of the ultrasonic probe 6 and the circumferential direction rotation of the tube blank, ensuring the comprehensiveness of flaw detection.

Belt 94b is connected to two pulleys 94a respectively; An isolator 94c is provided on the mounting base 1, and the transmission mechanism 94 is located inside the isolator 94c; Through the technical solution of this utility model, the two pulleys 94a are connected to the belt 94b, which transmits the rotational power of the lead screw 91 to the connecting shaft 82, ensuring that the displacement of the ultrasonic probe 6 and the rotation of the tube blank are always coordinated and linked. The isolation component 94c effectively blocks metal debris and dust generated during the flaw detection process, extends the service life of the transmission mechanism 94, and at the same time avoids the operator from accidentally touching the high-speed rotating transmission components, thus improving the safety of use.
