Description

Technical Field

[0001] This utility model relates to the field of aluminum-steel direct weld seam inspection technology, and in particular to auxiliary tooling for ultrasonic inspection of aluminum-steel direct weld seams. Background Technology

[0002] Ultrasonic testing of aluminum-steel direct welds is a crucial method for ensuring the quality of dissimilar metal welding. Its core lies in accurately identifying potential defects in the weld, such as cracks, lack of fusion, and porosity, especially addressing the testing challenges posed by the differences in physical properties between aluminum and steel. When inspecting aluminum-steel direct welds, the operator uses an ultrasonic flaw detector, placing the probe of the detector at the weld location for testing.

[0003] In existing technologies, when inspecting aluminum-steel straight weld seams, the operator holds the probe of the ultrasonic flaw detector and aligns it with the weld position for inspection. When manually holding the probe, it is easy for the probe to be tilted. The angular deviation will cause the ultrasonic wave propagation path to change, resulting in missed detections or misjudgments. To address these issues, we have designed an auxiliary tooling for ultrasonic inspection of aluminum-steel straight weld seams. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing an auxiliary tooling for ultrasonic testing of aluminum-steel straight weld seams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary fixture for ultrasonic testing of aluminum-steel straight weld seams includes two mounting frames and an ultrasonic flaw detector. A fixed frame is fixedly installed between the tops of the two mounting frames. The ultrasonic flaw detector is fixedly installed on the top of the fixed frame and connected to a connecting wire. A probe is fixedly installed at the bottom end of the connecting wire. A limiting mechanism is provided on the fixed frame. The connecting wire passes through the limiting mechanism and is fixedly connected to it. The limiting mechanism includes a limiting frame fixedly installed on the fixed frame. Limiting grooves are formed through the four side walls of the limiting frame. Sliding blocks are slidably connected in each of the four limiting grooves. Sliding rods are slidably connected to each of the four sliding blocks. A mounting block is fixedly installed between the ends of the four sliding rods. A connecting pipe is fixedly installed through the mounting block, and the connecting wire passes through the connecting pipe and is fixedly connected to it.

[0007] Preferably, a blocking block is fixedly installed at the end of each of the four sliding rods.

[0008] Preferably, a handle is fitted onto the connecting pipe, and the surface of the handle is provided with anti-slip texture.

[0009] Preferably, a mounting plate is fixedly mounted on each of the two mounting brackets, and a lighting lamp is fixedly mounted on the side wall of each of the two mounting plates.

[0010] Preferably, both mounting brackets are equipped with multiple locking casters at their bottoms.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. By setting up a limiting mechanism, when inspecting aluminum-steel straight weld seams, it can ensure that the probe on the ultrasonic flaw detector can maintain stable horizontal movement, thus ensuring the inspection effect.

[0013] 2. The lighting on the mounting plate provides illumination for the operator during testing, making the testing process easier.

[0014] In summary, the present invention has a reasonable structural design. When inspecting aluminum-steel straight weld seams, it can ensure that the probe on the ultrasonic flaw detector can move stably in the horizontal direction, thus ensuring the inspection effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-2An auxiliary fixture for ultrasonic testing of aluminum-steel straight weld seams includes two mounting brackets 1 and an ultrasonic flaw detector 3. Multiple locking casters 15 are installed at the bottom of each mounting bracket 1. A fixed bracket 2 is fixedly installed between the tops of the two mounting brackets 1. The ultrasonic flaw detector 3 is fixedly installed on the top of the fixed bracket 2. A connecting wire 4 is connected to the ultrasonic flaw detector 3, and a probe 5 is fixedly installed at the bottom end of the connecting wire 4. A limiting mechanism is provided on the fixed bracket 2, and the connecting wire 4 passes through and is fixedly connected to the limiting mechanism. The limiting mechanism includes components fixedly installed on the fixed bracket. The limiting frame 6 on the 2 has limiting grooves 7 through the four side walls of each limiting frame 6. Each of the four limiting grooves 7 has a slider 9 slidably connected to it. Each of the four sliders 9 has a sliding rod 10 slidably connected to it. Each of the four sliding rods 10 has a blocking block fixedly installed at its end. An installation block 8 is fixedly installed between the ends of the four sliding rods 10. A connecting pipe 11 is fixedly installed through the installation block 8. A handle 12 is fitted on the connecting pipe 11. The surface of the handle 12 has anti-slip texture. A connecting wire 4 passes through the connecting pipe 11 and is fixedly connected to it.

[0020] By setting up a limiting mechanism, when inspecting aluminum-steel straight weld seams, it can ensure that the probe 5 on the ultrasonic flaw detector 3 can maintain stable horizontal movement, thus ensuring the inspection effect.

[0021] Mounting plates 13 are fixedly mounted on both mounting brackets 1, and lighting lamps 14 are fixedly mounted on the side walls of both mounting plates 13.

[0022] The lighting lamp 14 on the mounting plate 13 provides illumination for the operator when performing inspection operations, making it easier for the operator to perform the inspection operations.

[0023] The functional principle of this utility model can be explained through the following operation methods:

[0024] Positioning phase

[0025] Push the mounting bracket 1 and move the tooling to the side of the aluminum-steel straight weld seam by locking the caster wheel 15, so that the probe 5 is aligned with the starting position of the weld seam.

[0026] Lock the casters 15 to fix the overall position of the fixture and prevent it from shifting during the inspection process.

[0027] Testing phase

[0028] The operator holds the connecting pipe 11 with the handle 12, and moves the sliding rod 10 and the slider 9 through the mounting block 8:

[0029] The slider 9 slides horizontally along the limiting groove 7 of the limiting frame 6 to ensure that the probe 5 moves horizontally along the weld direction.

[0030] During the movement, keep the handle 12 in place and apply force steadily so that the probe 5 passes through the weld area at a constant speed, while the ultrasonic flaw detector 3 records the test data simultaneously.

[0031] Final stage

[0032] After the inspection is completed, turn off the ultrasonic flaw detector 3 and the lighting lamp 14, and tidy up the connecting wires 4 to avoid tangling.

[0033] Unlock the casters 15, move the tool to the storage location, check that all parts are clean, and wipe and maintain them if necessary.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
