Description

Technical Field

[0001] This utility model relates to the field of automotive parts flaw detection technology, and in particular to an automotive parts flaw detection device. Background Technology

[0002] In today's booming automotive manufacturing industry, the quality of auto parts directly impacts the safety and reliability of the entire vehicle. As a key component of the automotive suspension system, the quality inspection of the control arm is particularly crucial. Automotive parts flaw detectors, with their high-precision and high-efficiency testing capabilities, have become an important tool for automotive manufacturers to control product quality. By conducting flaw detection on automotive control arms, potential internal defects such as cracks, porosity, and inclusions can be detected in a timely manner, effectively preventing traffic accidents caused by quality issues with the control arms and protecting the lives and property of consumers. With the continuous upgrading of the automotive industry and increasingly fierce market competition, higher demands are placed on the performance and testing accuracy of automotive parts flaw detectors, prompting continuous innovation and development in related technologies.

[0003] Currently, most automotive parts flaw detectors on the market use ultrasonic flaw detectors. The technical principle is based on the characteristics of ultrasonic waves being reflected, refracted, and scattered when they encounter different media interfaces during propagation in a medium. When ultrasonic waves enter the interior of a car's control arm and encounter a defect, some of the ultrasonic waves will be reflected back to the probe. The location, size, and nature of the defect can be determined by analyzing the characteristics of the reflected wave.

[0004] In actual testing, due to the irregular shape of the automotive swing arm, it is prone to deviation or swaying during transport on the conveyor belt, causing it to be out of position for inspection. Some areas may fall into the blind spot of the flaw detector, making defects in these areas undetectable and creating serious safety hazards. Furthermore, due to the inaccurate swing arm position, the flaw detector probe may collide or excessively rub against the automotive swing arm during inspection, damaging the probe, affecting inspection accuracy, shortening the lifespan of both the probe and the flaw detector, and increasing maintenance costs. Moreover, incomplete inspection due to swing arm position deviation may result in inaccurate test results, failing to accurately reflect the quality condition of the automotive swing arm. Therefore, a flaw detector for automotive parts is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automotive parts flaw detector, which aims to improve the problem of the inability to align the automotive swing arm during transport in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flaw detector for automotive parts includes a flaw detector housing, a flaw detector probe disposed inside the flaw detector housing, a side plate fixedly connected to the bottom of the flaw detector housing, a conveyor belt rotatably connected to the outer wall of the side plate, a support frame fixedly connected to the bottom of the side plate, a cleaning component disposed on the top of the side plate, and an alignment component disposed on the top of the side plate.

[0008] The positioning component includes a rubber disc and a sliding frame. The outer wall of the rubber disc is disposed on the top of the side plate, and the outer wall of the sliding frame is fixedly connected to the bottom of the side plate. Limit plates are fixedly connected to both ends of the sliding frame. A movable plate is slidably connected to the outer wall of the sliding frame, and a rack is fixedly connected to the outer wall of the movable plate. A drive component is disposed at the bottom of the rack. An L-shaped frame is fixedly connected to the top of the movable plate, and a fixed frame is fixedly connected to the other end of the L-shaped frame. The outer wall of the fixed frame is fixedly connected to the outer wall of the rubber disc.

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

[0012] The cleaning assembly includes a cleaning brush and a hair dryer. The cleaning brush is disposed on the top of the side panel, and the hair dryer is disposed on the top of the side panel. Two fixing posts are fixedly connected to the top of the side panel.

[0013] As a further description of the above technical solution:

[0014] Both of the fixed columns have telescopic columns slidably connected to their inner walls. Each telescopic column has a fixing hole inside. The outer wall of one telescopic column is fixedly connected to the outer wall of the telescopic cleaning brush, and the outer wall of the other telescopic column is fixedly connected to the outer wall of the hair dryer.

[0015] As a further description of the above technical solution:

[0016] A fixing block is fixedly connected to the outer wall of the fixing column, and a rotating rod is fixedly connected to the inner wall of the fixing block.

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

[0023] This utility model has the following beneficial effects:

[0024] In this invention, an L-shaped frame drives a fixed frame, which in turn drives a rubber disc, thus limiting the position of the car swing arm on the conveyor belt. This ensures the car swing arm is in the correct inspection position, preventing certain areas from being in the blind spot of the flaw detector and thus avoiding undetected defects and potential safety hazards. The flaw detector probe evenly covers all parts of the car swing arm that need inspection, ensuring comprehensive and thorough inspection of the entire arm. Furthermore, it prevents collisions or excessive friction between the probe and the car swing arm, protecting both the probe and the flaw detector, extending their lifespan, and reducing equipment maintenance costs.

[0025] In this invention, the height of the cleaning brush and the blower are adjusted by moving the second fixed column out of the fixed hole, which achieves the cleaning of the surface of the car swing arm of different sizes before flaw detection. This avoids the dust and impurities on the surface from generating reflective signals similar to defects, which could cause flaw detection personnel to misjudge that there are defects inside the car swing arm, or interfere with the reflective signals of defects, leading to the omission of actual defects. This ensures the reliability of the flaw detection results. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of an automotive parts flaw detector. Existing automotive parts flaw detectors typically consist of a main unit, probe, transmitting circuit, receiving circuit, and display circuit, used to detect defects inside automotive control arms. This is prior art and will not be described in detail here. The flaw detector housing 4 houses a flaw detector probe 5. A side plate 1 is fixedly connected to the bottom of the housing 4. A conveyor belt 2 is rotatably connected to the outer wall of the side plate 1. A support frame 3 is fixedly connected to the bottom of the side plate 1. A cleaning component and a positioning component are located on the top of the side plate 1. The positioning component includes a rubber disc 28 and a sliding frame 23. The outer wall of the rubber disc 28 is located on the top of the side plate 1, and the outer wall of the sliding frame 23 is fixedly connected to the bottom of the side plate 1. Limiting plates 25 are fixedly connected to both ends of the sliding frame 23 to restrict movement. The maximum distance of the moving plate 24 is to prevent it from falling off during adjustment. The outer wall of the sliding frame 23 is slidably connected to the moving plate 24. The moving plate 24 is used to drive the L-shaped frame 26 to move and align the car swing arm being conveyed. The outer wall of the moving plate 24 is fixedly connected to the rack 22. The bottom of the rack 22 is provided with a drive component. The top of the moving plate 24 is fixedly connected to the L-shaped frame 26. The other end of the L-shaped frame 26 is fixedly connected to the fixed frame 27. The fixed frame 27 is used to fix multiple rubber discs 28, which is practical for aligning car swing arms of different sizes. The outer wall of the fixed frame 27 is fixedly connected to the outer wall of the rubber disc 28. The surface of the rubber disc 28 is designed with anti-slip wave texture to align the car swing arm being conveyed on the conveyor belt 2 without damaging the car swing arm, so that all parts of the car swing arm that need to be inspected can be evenly covered by the probe of the flaw detector.

[0036] Reference Figures 1-3The drive assembly includes a motor 20, the outer wall of which is set at the bottom of the rack 22. A gear 21 is fixedly connected to the output end of the motor 20. The gear 21 meshes with the rack 22, and the gear 21 moves in conjunction with the rack 22, thereby driving the moving plate 24 to move relative to each other, thus achieving the alignment of the car swing arm during the conveying process. A base plate 19 is fixedly connected to the bottom of the motor 20, and a connecting post 18 is fixedly connected to the top of the base plate 19. The other end of the connecting post 18 is fixedly connected to the bottom of the side plate 1. The connecting post 18 and the base plate 19 are used to fix the motor 20 and prevent the motor 20 from shaking during the drive process. The cleaning assembly includes a cleaning brush 16 and a blower 17. The cleaning brush 16 has nylon bristles, which are not easy to scratch the paint or coating on the surface of the car swing arm. Meanwhile, it has good wear resistance and corrosion resistance, can withstand a certain degree of friction and chemical cleaning agents, and has a long service life. This is existing technology and will not be elaborated further here. The cleaning brush 16 is located at the top of the side plate 1, and the blower 17 is also located at the top of the side plate 1. The blower 17 is installed at an angle to prevent dust and impurities from entering the flaw detector housing 4 when cleaning the surface of the car swing arm. Two fixed posts 6 are fixedly connected to the top of the side plate 1. Telescopic posts 7 are slidably connected to the inner walls of both fixed posts 6. The telescopic posts 7 work in conjunction with the fixed posts 6 to extend and retract, thereby adjusting the height of the cleaning brush 16 and the blower 17 to accommodate different sizes of car swing arms. The telescopic posts 7 have fixed holes 8 inside. The outer wall of one telescopic post 7 is fixedly connected to the outer wall of the telescopic cleaning brush 16, and the outer wall of the other telescopic post 7 is fixedly connected to the outer wall of the blower 17. A fixed block 9 is fixedly connected to the outer wall of the fixed post 6. A rotating rod 10 is fixedly connected to the inner wall of the fixed block 9. A pressure plate 11 is rotatably connected to the outer wall of the rotating rod 10. The pressure plate 11 works in conjunction with the rotating rod 10 to adjust the height of the brush 16. Rod 10 performs a circular motion, thereby moving the fixed column 14 and achieving the effect of fixing the telescopic column 7. A sliding groove 12 is provided inside the pressure plate 11, and the fixed column 14 is installed inside the pressure plate 11. A rotating rod 13 is rotatably connected to the inner wall of the fixed column 14. The outer wall of the rotating rod 13 is slidably connected to the inner wall of the sliding groove 12. The sliding groove 12 cooperates with the rotating rod 13 to slide, preventing the rotating rod 13 from being unable to adjust its position when the pressure plate 11 is pressed, thus preventing the fixed column 14 from sliding out of the fixed position. Inside the fixed hole 8, the outer wall of the second fixed post 14 is slidably connected to the inner wall of the first fixed post 6, and the other end of the second fixed post 14 is slidably connected to the inner wall of the fixed hole 8. The fixed hole 8, together with the second fixed post 14, is used to fix the telescopic post 7, thereby achieving the effect of adjusting the height. A spring 15 is provided on the outer wall of the pressure plate 11. One end of the spring 15 is fixedly connected to the outer wall of the pressure plate 11, and the other end of the spring 15 is fixedly connected to the outer wall of the first fixed post 6. Through the rebound of the spring 15, the second fixed post 14 is always located inside the fixed hole 8 when the pressure plate 11 is not pressed.

[0037] Working principle: When the car swing arm is conveyed on the conveyor belt 2, the motor 20 drives the gear 21 to rotate. The rotation of the gear 21 drives the rack 22 to move in parallel. Then, the parallel movement of the rack 22 drives the moving plate 24 to move. In turn, the movement of the moving plate 24 drives the L-shaped frame 26 to move. Then, the movement of the L-shaped frame 26 drives the fixed frame 27 to move. Finally, the movement of the fixed frame 27 drives the rubber disc 28 to move. The rubber disc 28 aligns the car swing arm on the conveyor belt 2, so that the car swing arm is in the correct detection position, avoiding collision or excessive friction between the probe and the car swing arm. This protects the probe and flaw detector equipment, extends their service life, and reduces equipment maintenance costs.

[0038] Before flaw detection of the automotive swing arm, the swing arm is first initially cleaned with a cleaning brush 16. Then, a blower 17 removes the dust and impurities that the cleaning brush 16 could not remove. Next, the pressure plate 11 is pressed, which compresses the spring 15. The pressure plate 11 then moves the rotating rod 13, which in turn moves the fixing post 14. The fixing post 14 moves out of the fixing hole 8, releasing the limit on the telescopic post 7. The telescopic post 7 can be adjusted to accommodate different sizes of automotive swing arms. When it is necessary to fix the telescopic post 7, simply release the pressure plate 11. The spring 15 returns the pressure plate 11 to its original position, and then the fixing post 14 moves into the fixing hole 8, thus fixing the telescopic post 7. Removing dust and impurities can prevent them from forming interference points or blurry areas in the image, making the condition of the automotive swing arm surface clearly visible, which is convenient for operators to accurately judge whether there are defects and their characteristics.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
