[0002] Spatial fillet welds refer to fillet welds formed in space, which are usually used to connect the corners of two or more metal components. They are common in engineering with complex structures, such as construction, aerospace, and machinery manufacturing. The characteristics of spatial fillet welds include multi-angle contact surfaces and changes in the direction of the welds. Usually, special attention needs to be paid to the welding angle and position to ensure the strength and integrity of the weld. Inspecting spatial fillet welds is an important step to ensure welding quality and structural safety.

[0003] In the prior art, usually workers conduct visual inspections to observe the appearance, dimensions, edges, and angles of the welds, or use acoustic waves for detection to observe internal defects in the welds, such as pores, slag inclusions, or cracks. However, these instruments are usually held manually, and it is inevitable to shake during the detection process, which affects the detection results and cannot guarantee the welding quality.

A spring is arranged at one end inside the connecting sleeve. A fixing rod is slidably connected inside the connecting sleeve. A fixing block is arranged at the top end of the fixing rod. A guided wave excitation mechanism is arranged on one side of the fixing block.

[0006] As an improvement of the above technical solution, the guided wave excitation mechanism includes a guided wave box. A first mounting table is arranged at the top inside the guided wave box. A guided wave joint is arranged at the bottom of the first mounting table. An end cover is arranged at the bottom end of the guided wave joint. A guided wave cavity is arranged at the bottom of the end cover.

[0007] As an improvement of the above technical solution, a second mounting table is arranged on one side inside the guided wave box. An excitation joint is arranged at the bottom of the second mounting table.

[0008] As an improvement of the above technical solution, connecting plates are symmetrically arranged at the center of the top end of the moving frame, and the connecting plates are arranged on both sides of the empty slot.

[0009] As an improvement of the above technical solution, a first pulley is slidably connected to the bottom end of the moving frame. Accommodating grooves are symmetrically opened on both sides of the moving frame. A support rod is rotatably connected inside the accommodating groove. A second pulley is slidably connected to the bottom end of the support rod.

[0011] As an improvement of the above technical solution, receivers are symmetrically arranged on both outer sides of the waveguide box.

[0012] Beneficial effects of the utility model:

[0013] By arranging the movable frame in cooperation with the pilot excitation mechanism to ensure the stability during detection, and at the same time, in order to adapt to spatial angles at different angles, the movable frame is a foldable structure. The arc-shaped buckle is arranged in cooperation with the clamping groove to achieve fixation after bending. The connection between the movable frames is strengthened by the connecting plate on the top of the movable frame to enhance the stability. The connecting plate is a deformable material and can deform along with the bending of the movable frame.

Detailed implementation manners

[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0020] Please refer to Figures 1-4As shown in the figure, a spatial fillet weld feature guided wave excitation and reception device includes a moving frame 1. An empty slot 2 is opened at the top of the moving frame 1. Symmetrically fixed connection support blocks 4 are arranged inside the empty slot 2. A connecting sleeve 18 is fixedly connected to the outside of the support block 4. A spring 19 is arranged at one end inside the connecting sleeve 18. A fixing rod 20 is slidably connected inside the connecting sleeve 18. A fixing block 21 is arranged at the top end of the fixing rod 20. A guided wave excitation mechanism is arranged on one side of the fixing block 21.

[0021] Specifically, when the moving frame 1 is bent, the size of the empty slot 2 at its top will also change. When the empty slot 2 changes, the guided wave excitation mechanism, support block 4, fixing block 21, fixing rod 20, and connecting sleeve 18 inside it will not change, but the spring 19 inside the connecting sleeve 18 will deform due to the extrusion of the above structure. When the spring 19 is deformed by extrusion, the fixing rod 20 and the fixing block 21 will contract inward together to adapt to the smaller empty slot 2, thus not affecting the guided wave excitation mechanism.

[0022] Refer to Figures 1-4 , the guided wave excitation mechanism includes a guided wave box 5. A first mounting table 13 is arranged at the top inside the guided wave box 5. A guided wave joint 14 is arranged at the bottom of the first mounting table 13. An end cover 6 is arranged at the bottom end of the guided wave joint 14. A guided wave cavity 15 is arranged at the bottom of the end cover 6. A second mounting table 16 is arranged on one side inside the guided wave box 5. An excitation joint 17 is arranged at the bottom of the second mounting table 16.

[0023] Specifically, the first mounting table 13 and the second mounting table 16 facilitate the installation of the guided wave joint 14 and the excitation joint 17. The excitation joint 17 generates excitation signals (such as ultrasonic waves, sound waves, or electromagnetic waves) with specific frequencies and forms to excite the guided waves in the weld. The guided wave joint 14 cooperates with the guided wave cavity 15 to receive these guided waves in the weld.

[0024] Please refer to Figures 1-2 , connecting plates 3 are symmetrically arranged at the center of the top end of the moving frame 1. The connecting plates 3 are arranged on both sides of the empty slot 2.

[0025] Specifically, the connecting plates 3 can strengthen the connection between the moving frames 1 and enhance the stability. At the same time, the connecting plates 3 are made of deformable materials and can deform following the bending of the moving frame 1 while ensuring its connectivity.

[0026] Please refer to Figures 1-2 , a first pulley 9 is slidably connected to the bottom end of the moving frame 1. Accommodating grooves 7 are symmetrically opened on both sides of the moving frame 1. A support rod 8 is rotatably connected inside the accommodating groove 7. A second pulley 10 is slidably connected to the bottom end of the support rod 8.

[0027] Specifically, a support rod 8 is added to ensure the stability of the moving frame 1 during movement. Its structure can ensure that the moving frame 1 does not shake during movement. At the same time, for the convenience of movement, a first pulley 9 and a second pulley 10 are provided at the bottom of the moving frame 1 and the support rod 8.

[0028] Please refer to Figures 1-2 , a clamping groove 12 is provided at one end of the moving frame 1, and an arc-shaped buckle 11 is arranged in the clamping groove 12.

[0029] Specifically, in order to adapt to spatial angles at different angles, the moving frame 1 is a foldable structure. By setting the arc-shaped buckle 11 to cooperate with the clamping groove 12, fixation after bending can be achieved, thus facilitating detection.

[0030] Please refer to Figure 2 , receivers 22 are symmetrically arranged on both outer sides of the waveguide box 5.

[0031] Specifically, the receivers 22 convert the received signals into electrical signals and transmit them to the analysis device to be converted into forms of graphics, images or reports. Operators observe the weld quality and defect positions based on this information.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
