Description
Technical Field
[0001] This utility model relates to the field of weld defect detection technology, and in particular to an automated device for multi-angle X-ray detection of weld defects. Background Technology
[0002] Currently, the most widely used radiographic testing method utilizes X-ray or gamma-ray sources to emit penetrating radiation that penetrates the weld, exposing the film. The image of defects in the weld is then displayed on the processed radiographic film. It is mainly used to detect defects such as porosity, slag inclusions, cracks, and incomplete penetration within the weld.
[0003] For products assembled by welding, weld seams are usually left on the product. The reliability of the weld seam is one of the important factors affecting the product's performance.
[0004] In related technologies, the inspection of pipe welds is mostly carried out manually, which is time-consuming and labor-intensive. In addition, the pipe needs to be supported during the inspection process. Existing support devices are inconvenient to adjust and have poor applicability when supporting pipes of different sizes, which seriously affects the inspection efficiency.
[0005] Therefore, how to design an automated device for multi-angle X-ray inspection of weld defects has become a problem that we need to solve. Utility Model Content
[0006] To address the aforementioned problems, this invention proposes an automated device for multi-angle X-ray inspection of weld defects, thereby resolving the issues present in the prior art.
[0007] To achieve the above objectives, this utility model provides an automated device for multi-angle X-ray inspection of weld defects, comprising: a support assembly and a detection assembly. The support assembly includes a base, a first support seat, a second support seat, and a roller. Two first support seats are symmetrically mounted on the base, and two symmetrically distributed second support seats are slidably mounted on the first support seats. The roller is rotatably mounted on the second support seats, wherein a first motor for driving the roller to rotate is fixedly mounted at one end of each of the two second support seats.
[0008] The detection assembly includes a fixed frame, a second motor, a transverse screw, a movable seat, a cylinder, a mounting base, and an X-ray machine. Fixed frames are fixedly installed at both ends of the base. The second motor is fixedly installed on one side of the fixed frame. The transverse screw is rotatably installed between the two fixed frames, and the output end of the second motor is fixedly connected to the transverse screw. The movable seat is sleeved on the transverse screw and threadedly connected to it. The cylinder is fixedly installed on the top of the movable seat. The mounting base is fixedly installed on the piston end of the cylinder. The X-ray machine is detachably installed on the mounting base.
[0009] Furthermore, both sides of the mounting base are threaded with clamping bolts, and one end of each clamping bolt is fixedly connected to a clamping plate.
[0010] Furthermore, a transverse guide rod is fixedly installed between the two fixed frames, and the movable seat is slidably sleeved on the transverse guide rod.
[0011] Furthermore, a first bidirectional screw is rotatably mounted inside the base, and a third motor for driving the first bidirectional screw to rotate is fixedly mounted at one end of the base. The two first support seats are respectively sleeved on both ends of the first bidirectional screw and threadedly connected to the first bidirectional screw.
[0012] Furthermore, a first guide rod is fixedly installed inside the base, and the first support seat is slidably sleeved on the first guide rod.
[0013] Furthermore, a second bidirectional screw is rotatably mounted inside the first support base, and a fourth motor for driving the second bidirectional screw to rotate is fixedly mounted at one end of the first support base. The two second support bases are respectively sleeved on both ends of the second bidirectional screw and threadedly connected to the second bidirectional screw.
[0014] Furthermore, a second guide rod is fixedly installed inside the first support base, and the second support base is slidably sleeved on the second guide rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] Firstly, by setting up support and detection components, when inspecting pipe welds, the pipe can be placed on two adjacent rollers. The rollers on the two second support seats provide balanced support for both ends of the pipe. During inspection, the second motor can be started to drive the transverse screw to rotate, causing the transverse screw to drive the movable seat to slide laterally along the transverse guide rod. This allows the movable seat to move the X-ray machine above the weld to be inspected. Then, the cylinder is started to drive the mounting seat to descend, allowing the mounting seat to move the X-ray machine closer to the weld for inspection. This eliminates the need for manual inspection, saving time and labor, increasing automation, and improving inspection efficiency.
[0017] Secondly, by setting up a first bidirectional screw, a third motor, a first guide rod, a second bidirectional screw, a fourth motor, and a second guide rod, when inspecting pipes of different lengths, the third motor can be activated to drive the first bidirectional screw to rotate, causing the first bidirectional screw to drive the two first support seats to move relative to or in opposite directions along the first guide rod. This allows adjustment of the distance between the two first support seats, facilitating support for pipes of different lengths. When inspecting pipes of different diameters, the fourth motor can be activated to drive the second bidirectional screw to rotate, causing the second bidirectional screw to drive the two second support seats to move relative to or in opposite directions along the second guide rod. This allows adjustment of the distance between the two second support seats, facilitating support for pipes of different diameters and improving applicability. Attached Figure Description

By setting the detection component 2, during detection, the second motor 22 can be started to drive the transverse screw 23 to rotate, so that the transverse screw 23 drives the movable seat 24 to slide laterally along the transverse guide rod 210, so that the movable seat 24 drives the X-ray machine 27 to be adjusted above the weld to be tested. Then, the cylinder 25 is started to drive the mounting seat 26 to descend, so that the mounting seat 26 drives the X-ray machine 27 to approach the weld for detection. No manual inspection is required, saving time and effort and improving the degree of automation.
[0026] Both sides of the mounting base 26 are threaded with clamping bolts 28, and one end of the clamping bolts 28 is fixedly connected to a clamping plate 29.

[0028] Reference Figure 2 and Figure 3 The first support base 12 has a second bidirectional screw 19 rotatably mounted inside. A fourth motor 110 for driving the second bidirectional screw 19 to rotate is fixedly mounted at one end of the first support base 12.

By setting the second bidirectional screw 19, the fourth motor 110, and the second guide rod 111, when inspecting pipes of different diameters, the fourth motor 110 can be started to drive the second bidirectional screw 19 to rotate, so that the second bidirectional screw 19 drives the two second support bases 13 to move relative to or in opposite directions along the second guide rod 111, thereby adjusting the distance between the two second support bases 13 to facilitate support for pipes of different diameters.
[0029] The working process of this utility model is as follows: When inspecting pipe welds, the pipe can be placed on two adjacent rollers 14. The rollers 14 on the two second support seats 13 provide balanced support for both ends of the pipe. When inspecting pipes of different lengths, the third motor 17 can be started to drive the first bidirectional screw 16 to rotate, causing the first bidirectional screw 16 to drive the two first support seats 12 to move relative to or in opposite directions along the first guide rod 18, thereby adjusting the distance between the two first support seats 12 to facilitate support for pipes of different lengths. When inspecting pipes of different diameters, the fourth motor 110 can be started to drive the second bidirectional screw 19 to rotate, causing the second bidirectional screw 19 to drive the two second support seats 13 to move along the second guide rod. The relative or opposite movements of the 111 allow for adjustment of the distance between the two second support seats 13, facilitating support for pipes of different diameters and improving applicability. During inspection, the first motor 15 can be activated to drive the roller 14 to rotate, causing the roller 14 to rotate the pipe, facilitating selective inspection along the circumference of the pipe.

Then, the cylinder 25 is activated to drive the mounting seat 26 to descend, allowing the mounting seat 26 to drive the X-ray machine 27 closer to the weld for inspection. This eliminates the need for manual inspection, saving time and effort and improving automation.
