Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a material flaw detection test device for the production of automobile air-conditioning parts. Background Art

[0002] Automobile air conditioning parts refer to various components and parts used in automobile air conditioning systems, including compressors, condensers, evaporators, expansion valves, pipes, connectors, etc. Automobile air conditioning systems are directly related to the comfort and safety of drivers and passengers. Therefore, the quality of automobile air conditioning parts is of vital importance. By testing the materials used in the production of accessories with material flaw detection testing equipment, defects or problems inside the materials can be discovered in time to ensure the quality of accessories.

[0003] An existing material flaw detection test device for automobile air-conditioning parts production, when in use, sets a cleaning pool on the machine platform. The transducer set in the cleaning pool can effectively clean the parts materials placed on the placement rack, thereby improving the accuracy of flaw detection. After the surface cleaning of the parts raw materials is completed, the sewage is discharged by using a sewage pipe, and then the height distance of the parts raw materials is detected by using an infrared distance sensor. After the height information of the parts raw materials is transmitted to the PLC controller, the ultrasonic probe is raised and lowered to the same height by a vertical linear motor, and then its displacement is controlled by a horizontal linear motor. When the ultrasonic probe passes through the parts raw materials, the parts raw materials are flaw detected, and the detection data is transmitted to the ultrasonic flaw detection controller, which is displayed by the ultrasonic flaw detection controller. The equipment can realize the cleaning of the parts raw materials before flaw detection, improve the detection accuracy, is simple to operate, and has intelligent detection, and is suitable for popularization and use.

[0004] However, this method cannot clamp and fix the material when used. If the test device cannot clamp the material, the material will move or swing due to its own weight or external factors, resulting in an unstable position during the test, thereby affecting the accuracy and reliability of the detection results. The lack of a clamping device means that it is impossible to ensure that the position, angle and distance of the material in each test are consistent with the detection equipment, which will lead to inconsistency in the detection conditions and affect the comparability and repeatability of the test results.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4, the utility model provides an embodiment: a material flaw detection test device for the production of automobile air-conditioning accessories, comprising a workbench 1, both sides of the workbench 1 are fixedly connected with hydraulic cylinders 2, the output ends of the two hydraulic cylinders 2 are fixedly connected with movable plates 3, both sides of the movable plates 3 are fixedly connected with movable rods 4, the opposite ends of the multiple movable rods 4 are fixedly connected with movable plates 5, the bottom of the movable plate 5 is fixedly connected with a limiting component, the limiting component includes a limiting block 6, the limiting block 6 is fixedly connected to the bottom of the movable plate 5, the limiting block 6 is slidably connected to the outside of the limiting rod 7, the inside of the workbench 1 is provided with grooves on both sides, the limiting rod 7 is fixedly connected to the inside of the groove, the opposite sides of the two movable plates 5 are fixedly connected with clamping members 8, the outsides of the multiple movable rods 4 are sleeved with buffer springs 9, the multiple movable rods 4 are slidably connected to the inside of the workbench 1, one end of the buffer spring 9 is fixedly connected to the inside of the workbench 1, and the other end of the buffer spring 9 is fixedly connected to the movable plate 5.

[0025] The material to be tested is placed on the upper part of the workbench 1, and two hydraulic cylinders 2 are started. The output end of the hydraulic cylinder 2 is connected to the movable plate 3. When the hydraulic cylinder 2 is started, its output end will push the movable plate 3 to move. The movement of the movable plate 3 further drives the movement of the movable rod 4. The movable rod 4 is designed inside the workbench 1 and can slide inside it. This sliding enables the movable rod 4 to move quickly and accurately when needed. As the movable rod 4 moves, it will push the movable plate 5 to move accordingly. The movement of the movable plate 5 drives the limit block 6 to slide outside the limit rod 7. The limit rod 7 plays a role in guiding and limiting the range of movement, ensuring that the movable plate 5 will not deviate from the predetermined trajectory during the movement. Under the action of the limit block 6, the two movable plates 5 will drive the clamping members 8 to approach each other. During the movement of the movable plates 5, they will squeeze or stretch the buffer springs 9. The buffer springs 9 here play a role of buffering and shock absorption, which can absorb the impact and vibration generated during the movement and protect the material and the fixture itself from damage. Under the action of the clamping member 8, the material to be tested is tightly clamped and fixed on the workbench 1.

[0026] Reference Figure 1-Figure 3 A cylinder 10 is fixedly connected to the right part of the workbench 1, a fixed block 11 is fixedly connected to the output end of the cylinder 10, a support frame 14 is fixedly connected to the upper part of the fixed block 11, an electric push rod 15 is fixedly connected to the inside of the support frame 14, a mounting plate 16 is fixedly connected to the output end of the electric push rod 15, an ultrasonic probe 17 is fixedly connected to the inside of the mounting plate 16, a slide groove is opened at the rear part of the workbench 1, slide bars 13 are fixedly connected to the inside of the slide groove on both sides, sliders 12 are fixedly connected to the sides of the fixed block 11, the sliders 12 are slidably connected to the outside of the slide bars 13, return springs 18 are fixedly connected to the front sides of the support frame 14, and the other end of the return spring 18 is fixedly connected to the mounting plate 16.

[0027] When the cylinder 10 is started, its output end begins to generate power, pushing the fixed block 11 to move along a predetermined path. Driven by the fixed block 11, the slider 12 begins to slide outside the slide rod 13. The slide rod 13 not only provides a trajectory for the movement of the slider 12, but also ensures the smoothness and accuracy of its movement. As the slider 12 moves, the fixed block 11 begins to drive the support frame 14 to move. The movement of the support frame 14 further drives the movement of the mounting plate 16 and the ultrasonic probe 17. Through the power transmission of the cylinder 10, the ultrasonic probe 17 is accurately moved to the predetermined position. When the electric push rod 15 is started, its output end begins to generate thrust, pushing the mounting plate 16 to move further. In this process, the mounting plate 16 not only moves, but also stretches the reset spring 18. The reset spring 18 not only provides buffering and support for the movement of the mounting plate 16, but also ensures the stability and safety of the probe during the movement. The movement of the mounting plate 16 ultimately drives the ultrasonic probe 17 to adjust its position.

[0028] Working principle: First, place the material on the upper part of the workbench 1, start the two hydraulic cylinders 2, the output end of the hydraulic cylinder 2 drives the movable plate 3 to move, the movement of the movable plate 3 drives the movable rod 4 to move, so that the movable rod 4 slides inside the workbench 1, and the movable rod 4 moves, pushing the movable plate 5 to move, and the movable plate 5 moves, driving the limit block 6 to slide outside the limit rod 7, under the action of the limit block 6, the two movable plates 5 drive the clamping parts 8 to get closer, and the movable plate 5 squeezes or stretches the buffer spring 9 when it moves, and under the action of the clamping part 8, the material is clamped and fixed, so that the material can be effectively clamped and fixed, which can ensure that it maintains a stable position and posture during the flaw detection process, avoids the accuracy of the flaw detection results affected by the movement or swing of the material, and improves the flaw detection. The accuracy and reliability of the device are improved. When in use, the cylinder 10 is started, and the output end of the cylinder 10 pushes the fixed block 11 to move. When the fixed block 11 moves, it drives the slider 12 to slide outside the slide bar 13. Under the action of the slider 12, the fixed block 11 drives the support frame 14 to move. The movement of the support frame 14 drives the mounting plate 16 and the ultrasonic probe 17 to move. The electric push rod 15 is started, and the output end of the electric push rod 15 drives the mounting plate 16 to move. When the mounting plate 16 moves, the reset spring 18 is stretched. The movement of the mounting plate 16 drives the ultrasonic probe 17 to move for position adjustment, thereby facilitating the adjustment of the position of the ultrasonic probe 17. It can be flexibly adjusted according to the shape and size of the material to be measured, ensuring that all parts of the material to be measured are detected, thereby increasing the flexibility of the device.
