Description

Technical Field

[0001] This utility model relates to the field of torsion beam welding strength testing technology, and in particular to a torsion beam welding strength testing device. Background Technology

[0002] With the continuous expansion of the global automotive market, automobile production continues to climb. Large-scale production demands efficient and reliable quality inspection of every component, including torsion beams. Traditional inspection methods can no longer meet the needs of such massive production volumes, thus requiring more advanced welding strength testing equipment to ensure smooth production.

[0003] In existing technologies, some traditional devices rely on operators to spray magnetic powder onto the weld joint of a torsion beam, using the principle of magnetic leakage to detect whether the weld strength of the torsion beam meets the standard. However, the device needs to be stopped and started when the operator sprays the magnetic powder, which increases the operator's working time and reduces the efficiency of the test. Therefore, a torsion beam weld strength testing device is proposed. Utility Model Content

[0004] This utility model proposes a torsion beam welding strength testing device, which aims to improve the problem in the prior art where some devices need to be stopped and started when the operator sprays magnetic powder, which increases the operator's working time and reduces the testing efficiency.

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

[0006] A torsion beam welding strength testing device includes a base plate, a vertical plate fixedly connected to the top of the base plate, a limit groove formed in the inner wall of the vertical plate, two fixed blocks fixedly connected to the outer front side of the vertical plate, a rotating component providing transmission capability disposed on the outside of one of the fixed blocks, the rotating component being rotatably connected to the inner wall of the other fixed block, two connecting strips being detachably connected to the outside of the rotating component, a rotating shaft being passed through and connected to the outside of the two connecting strips and the inner wall of the rotating component, a fixed shaft being fixedly connected inside the two connecting strips, and a material transfer component providing telescopic capability disposed on the outside of the fixed shaft.

Overall, it improves the efficiency and accuracy of the test and ensures the reliability of the welding strength test of the torsion beam.

[0008] As a further description of the above technical solution:

[0009] The rotating assembly includes a motor, multiple bolts, a threaded rod, a transmission block, and a connecting block.

[0010] In the above technical solution, the motor is securely installed with bolts, driving the threaded rod to rotate. The transmission block slides along the limiting groove under the action of the thread, causing the connecting block to move. This design provides stable transmission, detachable connection for easy maintenance, precise control of the connecting bar position, and reliable transmission for subsequent testing.

[0011] As a further description of the above technical solution:

[0016] The above technical solution, in this design, connects the conveying pipe to the hollow pipe and the storage box, ensuring stable material conveying. The outer shell is reinforced by fixing bolts, which protects the internal components.

[0017] As a further description of the above technical solution:

[0018] The top of the base plate is detachably connected to two connecting plates. Two bolts are inserted through the outside of the two connecting plates and the inner wall of the base plate. A main board is fixedly connected to the outside of the two connecting plates.

[0019] The above technical solution employs a detachable connection method, using bolts to connect the connecting plate to the base plate, thereby securing the main board. This makes equipment installation and disassembly convenient, facilitating transportation and maintenance. Simultaneously, the stable connection ensures the main board's stability, providing reliable support for subsequent testing components.

[0020] As a further description of the above technical solution:

[0021] The motherboard has a slide plate fixedly connected inside, and a detection component that provides rotation capability is provided on the top of the motherboard. A limit block is fixedly connected to the top of the motherboard.

[0022] In the above technical solution, the sliding plate inside the motherboard provides a stable sliding track for the detection component, and the top detection component has the ability to rotate, allowing for flexible adjustment of the detection angle. The limiting block can precisely limit the movement range of the detection component, ensuring a stable and accurate detection process, and improving the reliability and efficiency of the torsion beam welding strength detection.

[0023] As a further description of the above technical solution:

[0024] The detection assembly includes a second motor, a bidirectional lead screw, a drive wheel, a driven wheel, a belt, two telescopic rods, and two sliders. The bottom of the second motor is fixedly connected to the top of the main board. One end of the bidirectional lead screw is fixedly connected to the output end of the second motor, and the other end of the bidirectional lead screw is rotatably connected to the inner wall of the limiting block. The drive wheel is fixedly connected to the outside of the bidirectional lead screw. The inner walls of the two sliders are threadedly connected to the outside of the bidirectional lead screw, and the bottoms of the two sliders are slidably connected to the inside of the slide plate. The outside of the two telescopic rods is rotatably connected to the inner walls of the two sliders. A driven wheel is fixedly connected to the outside of one of the telescopic rods. A belt is fitted around the outside of the driven wheel and the drive wheel.

[0025] In the above technical solution, this detection component uses a two-way lead screw driven by a motor to move a slider along a slide plate, thereby adjusting the position of the telescopic rod. The drive wheel drives the driven wheel via a belt, causing the telescopic rod to rotate. This allows for multi-angle and multi-position detection of the torsion beam, improving detection flexibility and accuracy, and ensuring reliable welding strength testing.

[0026] As a further description of the above technical solution:

[0027] Both telescopic rods are fixedly connected to clamps on the outside, and the two clamps are located on the same horizontal plane. The bottom of the base plate is fixedly connected to two sets of feet.

[0028] The aforementioned technical solution ensures that the clamps on the telescopic rod are on the same horizontal plane, allowing for stable and precise clamping of the torsion beam and ensuring uniform force distribution during testing. The feet at the bottom of the base plate provide support and cushioning, enhancing equipment stability, reducing vibration impact, and resulting in a smoother testing process and more reliable results.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, after the operator adjusts the angle of the connecting strip, it is fixed by the rotating shaft. The cylinder is started to drive the piston head to make telescopic movements inside the hollow tube, which compresses the air inside the hollow tube and sprays the magnetic powder from the nozzle onto the welded joint of the torsion beam. Conversely, when the cylinder moves in the opposite direction, it causes the conveying pipe to generate suction, which draws the magnetic powder prepared in advance from the storage box into the hollow tube. After the magnetic powder is sprayed, this structure achieves the effect of starting the device while spraying powder, which solves the problem that the device needs to be stopped and started when the operator is spraying magnetic powder, which increases the operator's working time and reduces the efficiency of detection.

[0031] 2. In this utility model, the operator starts the second motor to rotate, which drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate via a belt, which in turn drives one of the telescopic rods to rotate. At the same time, since the two sliders are threadedly connected to the bidirectional lead screw and slide in the slide plate, the rotation of the bidirectional lead screw causes the two sliders to move in opposite directions. This structure achieves the effect of slowly bending the torsion beam, further detecting the welding strength of the torsion beam, and solving the problem that some existing devices have limited detection methods and cannot detect details when testing torsion beams.

They are used to connect the base plate 1 and the main board 22, and fix the main board 22 on the base plate 1 to ensure the installation stability of the detection component.

[0045] Two bolts 21 are installed on the outer sides of the two connecting plates 20 and the inner wall of the base plate 1 to fix the connecting plates 20 to the base plate 1, facilitating the installation and disassembly of the equipment and ensuring a firm and reliable connection between the connecting plates 20 and the base plate 1. A main plate 22 is fixedly connected to the outer side of the two connecting plates 20, and a sliding groove plate 23 is fixedly connected inside the main plate 22, providing a sliding track for the slider 31. This ensures that the slider 31 can slide smoothly under the drive of the bidirectional lead screw 25, improving the motion accuracy of the detection component. The top of the main board 22 is equipped with a detection component that provides rotational capability. A limit block 26 is fixedly connected to the top of the main board 22. The detection component includes a second motor 24, a bidirectional lead screw 25, a drive wheel 27, a driven wheel 28, a belt 29, two telescopic rods 30, and two sliders 31. The bottom of the second motor 24 is fixedly connected to the top of the main board 22. One end of the bidirectional lead screw 25 is fixedly connected to the output end of the second motor 24, and the other end of the bidirectional lead screw 25 is rotatably connected to the inner wall of the limit block 26. The outer side of the bidirectional lead screw 25... A drive wheel 27 is fixedly connected to the base plate 1. The inner walls of two sliders 31 are threadedly connected to the outside of a double-acting screw 25. The bottoms of the two sliders 31 are slidably connected to the inside of a slide plate 23. The outer sides of two telescopic rods 30 are rotatably connected to the inner walls of the two sliders 31. A driven wheel 28 is fixedly connected to the outside of one of the telescopic rods 30. A belt 29 is fitted around the outside of the driven wheel 28 and the drive wheel 27. Clamps 32 are fixedly connected to the outside of both telescopic rods 30 to clamp the torsion beam. The clamps are made of pressure-resistant material. The two clamps 32 are located on the same horizontal plane. Two sets of feet 34 are fixedly connected to the bottom of the base plate 1 to support the bottom of the device.

[0046] Working principle: First, the welded area of ​​the torsion beam and its surroundings are cleaned to remove impurities such as oil, rust, and scale. The welded area of ​​the torsion beam to be tested is magnetized and placed between two clamps 32 to hold the torsion beam. The detection assembly is activated: Motor 24 rotates, driving the bidirectional lead screw 25 to rotate. The bidirectional lead screw 25 drives the drive wheel 27 to rotate, which in turn drives the driven wheel 28 via belt 29, thereby rotating one of the telescopic rods 30. Simultaneously, since the two sliders 31 are threadedly connected to the bidirectional lead screw 25 and slide within the slide plate 23, the rotation of the bidirectional lead screw 25 causes the two sliders 31 to move relative to each other, thereby moving the two telescopic rods 30. Because the torsion beam itself has a certain degree of curvature, when the two clamps 32 clamp the torsion beam and move it towards the center, the torsion beam will be compressed, thus detecting the strength of the torsion beam weld.

[0047] Then, the rotating assembly is started: the motor 4 drives the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the transmission block 7 and the transmission block 7 slides in the limiting groove 33, the transmission block 7 moves along the threaded rod 6. The transmission block 7 drives the connecting block 8 to move. After moving to the welding position of the torsion beam, the operator adjusts the angle of the connecting strip 10 and fixes it by the rotating shaft 9. The cylinder 12 is started to drive the piston head 14 to make telescopic movements inside the hollow tube 15, so that the air inside the hollow tube 15 is compressed and the magnetic powder is sprayed from the nozzle 16 to the welding position of the torsion beam. Conversely, when the cylinder 12 moves in the opposite direction, the conveying pipe 17 generates suction, which draws the magnetic powder prepared in advance in the storage box 18 into the interior of the hollow tube 15. After the magnetic powder is sprayed, since the torsion beam is generally made of ferromagnetic material, the magnetic powder detection is based on the principle of magnetic leakage. When the welded parts of a torsion beam are magnetized, if there are defects on or near the surface, such as cracks, inclusions, or lack of fusion, these defects will cause distortion of the magnetic field lines, generating a leakage magnetic field. Magnetic powder applied to the workpiece surface will be attracted by the leakage magnetic field, forming magnetic traces. Under suitable lighting conditions, these magnetic traces can be visually observed, thus revealing the location, size, and shape of the defects.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
