Description

Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a non-destructive testing equipment. Background Art

[0002] Nondestructive testing is a method of evaluating the quality and safety of materials by detecting changes in various physical phenomena caused by abnormalities or defects in the internal structure of the material without destroying the object being tested. This technology is widely used in aerospace, automobile manufacturing, petrochemical and other industries. It can not only improve product reliability, but also effectively reduce production costs. With the rapid development of the manufacturing industry and technological progress, the requirements for product quality are getting higher and higher. Nondestructive testing equipment is also constantly innovating and developing to meet increasingly stringent testing standards and higher testing efficiency requirements.

[0003] At present, common non-destructive testing equipment is mainly composed of a frame, a power component and a detection component. Among them, the power component is responsible for transporting the workpiece to be tested to the designated location, and the detection component captures the tiny defect information inside the workpiece by applying a magnetic field, ultrasonic wave or other forms of energy to the workpiece. However, these devices can usually only detect a single type of defect. For example, magnetic flaw detection is mainly used to detect cracks, pores and other problems in metal parts. In order to cope with complex and diverse testing needs, the industry generally adopts the method of using multiple production lines or multiple devices together, and each production line or each device is dedicated to the detection of a specific type of defect. Although this method can guarantee the accuracy of the test results to a certain extent, it also has obvious shortcomings.

[0004] Specifically, most existing nondestructive testing equipment adopts a single-line design and can only complete one testing task at a time. When a comprehensive quality inspection is required, the workpiece must be transferred to different testing lines multiple times, which not only increases the workload of the operator, but also may cause the risk of secondary damage to the workpiece during the transfer process. In addition, the multi-line design also makes the overall footprint larger, increasing the difficulty of maintenance and management, which in turn affects production efficiency and economic benefits. Summary of the invention

[0005] In order to achieve efficient testing of multiple projects on a single testing line at the same time, the present application provides a non-destructive testing device.

[0006] The nondestructive testing equipment provided in this application adopts the following technical solution: A nondestructive testing device includes a frame and a power component and a detection component arranged on the frame, wherein the power component is used to transport a piece to be tested, the number of the detection components is more than two, the detection component is provided with a slide, the slide is slidably connected to the frame, the slide is rotatably provided with a supporting wheel, and the supporting wheel is located below the conveying direction of the power component to support the piece to be tested.

[0007] By adopting the above technical solution, it is possible to achieve flexible adjustment of multiple inspection items on a single inspection line. Specifically, when a single inspection item is required, the corresponding inspection component can be slid onto the conveying path of the power component to perform the required single inspection; at the same time, other inspection components can be slid to the support wheel on the conveying path of the power component, which only plays a supporting role. When multiple inspection items are required, the inspection components of the required related inspection items can all be slid onto the conveying path of the power component, so that multiple inspection items can be completed on the same inspection line, avoiding multiple turnovers and improving inspection efficiency.

[0008] Preferably, a demagnetization component is provided at the end of the frame located in the conveying direction of the power component.

[0009] By adopting the above technical solution, the workpiece can be effectively demagnetized after the inspection to avoid the negative effects that may be caused by residual magnetism, such as attracting iron filings and causing performance degradation of parts, thereby improving the quality and reliability of the product after inspection.

[0010] Preferably, the demagnetization component includes a DC demagnetization machine and an AC demagnetization machine.

[0011] By adopting the above-mentioned technical solution, the present application integrates the DC demagnetization machine and the AC demagnetization machine and connects them in series to the frame, which can better demagnetize the workpiece. Specifically, AC demagnetization method: place the parts in an alternating magnetic field, gradually reduce the current or slowly withdraw it. This method is fast and suitable for surface demagnetization. DC demagnetization method: use the original DC magnetic field, continuously change its magnetic field direction, and gradually reduce the magnetizing current to zero. This method is suitable for occasions where deep demagnetization is required. The present application integrates the two demagnetization methods and connects them in series to the frame to better demagnetize the workpiece, or flexibly select the demagnetization method according to needs, with better flexibility.

[0012] Preferably, the frame is provided with a lifting platform, and the slide seat is slidably connected to the lifting platform.

[0013] By adopting the above technical solution, the setting of the lifting platform can more flexibly realize the height adjustment of the detection component, thereby obtaining a better flaw detection effect. In addition, the multi-directional adjustment of the detection component can be more flexibly realized in conjunction with the slidable state of the detection component.

[0014] Preferably, a marking component is provided at the end of the frame located in the conveying direction of the power component, and the number of the marking components corresponds to the number of the detection components.

[0015] By adopting the above technical solution, it is possible to achieve targeted marking at the end of a single inspection line based on the results of different inspection components. Specifically, when a certain inspection component finds a defect in the inspection item it is responsible for, the workpiece will continue to move along the conveying direction of the power component to the corresponding marking component, and the marking component will specifically mark the defect position. Each inspection component corresponds to a unique marking component, ensuring that different types of defects can be accurately marked at different locations, avoiding the problem of confusing or repeated markings, and improving the accuracy of the inspection results and the convenience of post-processing.

[0016] Preferably, the frame is provided with a marking box, the marking box is provided with a material passing hole for the workpiece to pass through, the marking box is penetrated by a swing hole, a mounting rod is passed through the swing hole and the mounting rod can slide along the length direction of the swing hole, the marking component is arranged on the mounting rod, the marking box is rotatably provided with a driven gear ring, the driven gear ring is coaxial with the swing hole, the marking box is rotatably provided with a driving gear, the driving gear is meshed with the driven gear ring, and the marking box is provided with a swing driving member for driving the driving gear to rotate.

[0017] By adopting the above technical solution, when there are defects of multiple inspection items in the same part of the workpiece, conventional marking will cause overlapping and unclear marks. Therefore, the present application adopts a rotating marking method, that is, the marking component is in a state of continuous reciprocating swing, so that the workpiece can be marked within a certain arc range along the circumference, reducing the problem of overlapping marking positions at one point. Specifically, for example, after the previous marking component is marked at a certain angle position of the same section, it is transported to the next marking component, and the angle of the next marking component after swinging will be different from the marking angle of the previous marking component. Therefore, although the next marking component also needs to be marked at the same section position, the marking angle position is different, so it is possible to achieve marking at different angles of the same section. In subsequent observations, clear marks representing different defects can be obtained with a greater probability.

[0018] Preferably, the power assembly includes a lower driving wheel, a lower driving member, an upper driving wheel and an upper driving member, the lower driving wheel is rotatably connected to the frame, the lower driving member is connected to the frame and used to drive the lower driving wheel to rotate, the upper driving wheel is rotatably connected to the frame, the upper driving member is connected to the frame and used to drive the upper driving wheel to rotate, and a channel for conveying workpieces is formed between the upper driving wheel and the lower driving wheel.

[0019] By adopting the above technical solution, the coordinated work between the upper and lower drive wheels is achieved, ensuring that the workpiece can be transported smoothly and efficiently in the testing equipment. Specifically, the lower drive wheel is rotatably connected to the frame and driven by the lower drive member, which ensures the stability and reliability of the workpiece during transportation; the upper drive wheel is rotatably connected to the frame and driven by the upper drive member, which further improves the accuracy and speed of workpiece transportation. The conveying channel formed between the upper drive wheel and the lower drive wheel enables the workpiece to maintain the correct posture during the inspection process, avoiding inspection errors caused by tilt or offset. Overall, this design significantly improves the working efficiency and inspection quality of non-destructive testing equipment.

[0020] Preferably, the number of the lower driving wheels is more than two, and lower conveyor belts are arranged on the outer sides of some of the lower driving wheels.

[0021] By adopting the above technical solution, multiple lower drive wheels and the lower conveyor belt arranged on their outer sides can ensure the stability and reliability of the workpiece during the transportation process. Specifically, multiple lower drive wheels disperse the transmission load, reduce the wear rate of a single drive wheel, and extend the service life of the equipment. At the same time, the lower conveyor belt can not only provide a continuous and stable conveying platform, but also effectively support the workpiece when the workpiece is heavy, preventing it from being deformed or damaged due to excessive local force. In addition, the lower conveyor belt can also play a buffering role, reducing the impact on the workpiece during transportation, and further improving detection accuracy and work efficiency.

[0022] Preferably, the frame is rotatably provided with a swing arm, and a tensioning wheel is rotatably provided at one end of the swing arm away from the connection with the frame, the tensioning wheel abuts against the inner wall of the lower conveyor belt, and the frame is provided with a tensioning drive component for maintaining the tensioning wheel in a tight state with the lower conveyor belt.

[0023] By adopting the above technical solution, the frame is rotatably provided with a swing arm, and a tensioning wheel is rotatably provided at one end of the swing arm away from the connection with the frame, and the tensioning wheel abuts against the inner wall of the lower conveyor belt. At the same time, the frame is provided with a tensioning drive for maintaining the tensioning wheel and the lower conveyor belt in a tight state. This design can effectively ensure that the lower conveyor belt is always in a suitable tensioning state, prevent relaxation due to long-term use, and thus ensure the stability and reliability of the workpiece during the transportation process. Specifically: the tensioning wheel contacts the inner wall of the lower conveyor belt, and the tension of the conveyor belt can be adjusted at any time during operation to avoid loosening. The setting of the swing arm enables the tensioning wheel to move within a certain range, adapt to different working environments and changes in conditions, and improve the flexibility of the system. The position of the tensioning wheel is controlled by the tensioning drive to ensure that the tensioning wheel always maintains effective contact with the inner wall of the lower conveyor belt, maintain appropriate tension, and further ensure the stability of workpiece transportation. These measures work together to improve the overall performance and stability of the non-destructive testing equipment.

[0024] Preferably, a movable block is arranged above the frame and a lifting drive member for lifting the movable block is arranged between the frame and the movable block, the upper driving wheel is rotationally connected to the movable block, and the upper driving member is connected to the movable block.

[0025] By adopting the above technical solution, the lifting and lowering adjustment function of the upper drive wheel is realized. Specifically, a movable block is set above the frame, and the movable block is moved up and down by a lifting drive member, so that the upper drive wheel can be raised and lowered synchronously with the movable block. This design not only improves the adaptability of the equipment, and can switch between workpieces of different sizes and shapes, but also enhances the stability and reliability during the workpiece transportation process. At the same time, the rotational connection between the upper drive wheel and the movable block ensures that the upper drive wheel can still rotate smoothly during the lifting process, further improving the overall performance of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up multiple inspection components and sliding them on the rack, flexible adjustment and inspection of multiple items can be achieved on a single inspection line, without the need to frequently transfer workpieces, which significantly improves inspection efficiency; 2. The increase in the number of detection components and the design of the slide make it possible to quickly adjust the position of the detection components according to actual detection needs, enhancing the adaptability and flexibility of the equipment; 3. The setting of the supporting wheels ensures that other testing components can stably support the test pieces when not in operation, thus avoiding wear and energy waste caused by idling of the equipment.

[0029] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0030] The inventor of the present application has found that nondestructive testing equipment is usually a single testing line for testing a corresponding single testing item. When multiple items need to be tested, the workpiece needs to pass through multiple testing lines for testing and needs to be transferred between multiple testing lines. The entire process is relatively cumbersome and is not conducive to improving the testing efficiency. For this reason, the present application mainly adopts the following design of sliding connection of multiple testing components, which achieves the effect of selectively completing multiple testing items on the same testing line, thereby improving the testing efficiency. The following is a further detailed description of the present application.

[0031] Example 1 Reference Figure 1 The nondestructive testing equipment provided in the embodiment of the present application includes a frame 1 and a detection component 2, a demagnetization component 3 and a marking component 4 which are sequentially arranged on the frame 1. In this embodiment, the detection component 2 uses a magnetic flaw detection component and is used to detect specific detection items. The demagnetization component 3 is used to eliminate the residual magnetic field of the workpiece, and the marking component 4 is used to mark the defects of specific items on the defective parts found during the workpiece detection process. In addition, power components 5 are also arranged on both sides of the detection component 2. The power components 5 run through the entire conveying process of the workpiece and are used to convey the workpiece to be inspected. Among them, the number of detection components 2 is more than two, and this embodiment takes two detection components 2 as an example for description.

[0032] Reference Figure 2 and Figure 3, a lifting platform 21 is fixed to the top surface of the frame 1 by bolts. The lifting platform 21 can use a hydraulic cylinder or an electric push rod as a driving source, and the lifting speed and height are controlled by a controller. For example, the hydraulic cylinder has a large thrust and stability, which is suitable for applications under heavy load environments; the electric push rod has a fast response speed and is convenient for precise control. In addition, a limit switch and a safety protection mechanism can be set on the lifting platform 21 to prevent accidents. The top surface of the lifting platform 21 is slidably connected to a slide 22, and the sliding connection between the slide 22 and the lifting platform 21 can be in the form of a T-slot and a guide key to ensure that the slide 22 always remains stable during the lifting process. For example, the T-slot can provide reliable guidance and support, while the guide key can reduce wear during sliding and extend the service life. In this embodiment, the detection component 2 is actually fixedly connected to the slide 22 by bolts to form a stable whole.

[0033] The setting of the lifting platform 21 can more flexibly realize the height adjustment of the detection component 2, thereby obtaining a better flaw detection effect. Especially when detecting large or heavy workpieces, the height of the detection component 2 can be conveniently adjusted through the lifting platform 21, so that it is closer to the surface of the workpiece, thereby improving the detection accuracy.

[0034] Reference Figure 2 and Figure 3 , the slide 22 is located on the side of the lifting platform 21 and is also provided with a supporting wheel 23 through a bracket rotation. Only one of the supporting wheel 23 and the detection component 2 can be moved to the conveying direction of the power component 5, and a corresponding stop module is provided on the slide 22. These detection components 2 can be slid manually or electrically along the direction perpendicular to the workpiece conveying to adjust their positions. For example, when a single detection item is required, a corresponding detection component 2 can be slid to the conveying path of the workpiece, and the other detection component 2 can be slid to the supporting wheel 23 on the conveying path of the workpiece. At this time, only a single detection item is detected, and the other detection component 2 is vacant and the supporting wheel 23 is used for support; when multiple detection items are required, both detection components 2 can be slid to the conveying path of the workpiece, so as to achieve the completion of multiple detection tasks on the same detection line.

[0035] In addition, the sliding connection between the slide 22 and the frame 1 can be in the form of a linear guide and a slider, or a combination of a ball screw and a nut. Both methods can achieve high-precision positioning and stable movement. For example, a linear guide has a high load-bearing capacity and low friction resistance, which is suitable for long-term continuous work; a ball screw can achieve a large stroke in a small space and has strong adaptability. The supporting wheel 23 can be made of rubber material, which has good shock absorption and anti-skid effects, and prevents the detected parts from being offset or damaged during the transportation process.

[0036] Reference Figure 3and Figure 4 The power assembly 5 includes a lower driving wheel 51, a lower driving member 54, an upper driving wheel 52 and an upper driving member 55. In this embodiment, the lower driving wheels 51 are a pair and are both rotatably connected to the frame 1 through bearings, and the outer sides of the two lower driving wheels 51 are sleeved with a lower conveyor belt 53. During the actual transportation process, the workpiece is supported on the lower conveyor belt 53 for transportation. The lower driving member 54 is a motor, which is connected to the frame 1 and is used to drive the two lower driving wheels 51 and the lower conveyor belt 53 to rotate. The frame 1 is also rotatably provided with a swing arm 56 through a rotating shaft, and a tensioning wheel 57 is rotatably provided at the bottom of the swing arm 56, and the tensioning wheel 57 is located inside the lower conveyor belt 53 and is in a tight state with the inner wall of the lower conveyor belt 53. The frame 1 is also rotatably provided with a tensioning driving member 58, which is a telescopic member such as a cylinder, and the end of the tensioning driving member 58 is rotatably connected to the swing arm 56, and the tensioning driving member 58 is used to apply force to the swing arm 56 to rotate so as to keep the tensioning wheel 57 and the lower conveyor belt 53 in a tight state.

[0037] A movable block 11 is arranged above the frame 1, and the frame 1 and the movable block 11 are slidably connected via a guide post 12. A lifting drive 13 for lifting and lowering the movable block 11 is arranged on the top of the guide post 12. In this embodiment, the upper driving wheels 52 are also a pair and are rotatably connected to the corresponding movable blocks 11. The upper driving wheels 52 and the lower driving wheels 51 correspond to each other in the upper and lower directions. In the actual conveying process, the upper driving wheels 52 and the upper driving wheels 52 are used to clamp and convey the two sides of the same position of the workpiece at the same time, so as to improve the stability during the conveying process.

[0038] In this embodiment, the upper driving member 55 is a motor connected to the movable block 11 to drive the upper driving wheel 52 to rotate. A channel for conveying workpieces is formed between the upper driving wheel 52 and the lower driving wheel 51, and the thickness of the conveying channel can be adjusted. The power assembly 5 designed in this way can effectively clamp and convey workpieces of various shapes and sizes, ensuring the reliability of the detection process.

[0039] Reference Figure 1 The demagnetization component 3 is used to demagnetize the inspected part to avoid the influence of residual magnetism generated during the flaw detection process on the performance of the part. Especially for shaft parts, residual magnetism may attract iron filings, causing friction damage to the parts during rotation. Therefore, the existence of the demagnetization component 3 is very necessary.

[0040] Specifically, the demagnetization component 3 includes a DC demagnetizer 31 and an AC demagnetizer 32. The AC demagnetization method is suitable for surface demagnetization by placing the parts in an alternating magnetic field and gradually reducing the current or slowly withdrawing it; the DC demagnetization method uses the original DC magnetic field to continuously change its magnetic field direction and gradually reduce the magnetizing current to zero, which is suitable for deep demagnetization. The present application integrates the two demagnetization methods and connects them in series to the frame 1. You can choose to use one of them or use them in combination, which is more flexible.

[0041] Reference Figure 1 and Figure 5 , the marking component 4 is installed inside the marking box 41, and the marking box 41 is installed on the frame 1. The number of marking components 4 corresponds to the number of detection components 2, so there are two marking components 4 in this embodiment, so as to perform different defect markings on the defect positions found during the detection process of the two detection components 2. When a defect is found at a specific position of the workpiece during the detection process of the specific detection component 2, the specific defect can be specifically marked at the position by the specific marking component 4 when the position is transported to the marking component 4. The marking style of each marking component 4 is different, so that different defects can be marked at different locations of the workpiece.

[0042] Specifically, the marking component 4 can be in various forms such as a laser marking machine, an inkjet printer or a dot-peen marking machine. For example, a laser marking machine has the characteristics of high precision and durability, and is suitable for the field of precision processing; an inkjet printer can realize color marking and intuitively display the nature of different defects; a dot-peen marking machine is simple and durable, and is suitable for mass production. According to actual needs, a suitable marking method can be selected.

[0043] Reference Figure 5The marking box 41 is provided with a feeding hole 42 along the conveying direction of the workpiece. In addition, the side wall of the marking box 41 is provided with an arc-shaped swing hole 43 with the center of the feeding hole 42 as the center. A mounting rod 44 is passed through the swing hole 43 and the mounting rod 44 can swing along the arc of the swing hole 43. The two marking components 4 are actually fixed to the mounting rod 44 through the bracket and bolts. The outer wall of the marking box 41 is provided with a driven gear ring 45 through the bearing rotation. The driven gear ring 45 is coaxial with the swing hole 43, and the internal hollow part of the driven gear ring 45 can allow the workpiece to pass through to achieve normal conveying. The outer wall of the marking box 41 is also provided with a driving gear 46 through the bracket rotation, and the driving gear 46 is meshed with the driven gear ring 45. The outer wall of the marking box 41 is also fixed with a swing drive 47 by bolts. The swing drive 47 is a motor that can realize positive and negative rotation to realize the positive and negative rotation of the driving gear 46, and the driven gear ring 45 rotates positive and negative to finally realize the reciprocating swing of the mounting rod 44 and the marking component 4. The marking component 4 designed in this way can realize multi-angle marking and avoid the problem of overlapping marks. When there are defects in multiple inspection items in the same part of the workpiece, conventional marking will cause overlapping and unclear marks. Therefore, the present application adopts a rotating marking method, that is, the marking component 4 is in a state of continuous reciprocating swing, so that the workpiece can be marked within a certain arc range along the circumferential direction, reducing the problem of overlapping marking positions at one point. Specifically, for example, after the previous marking component 4 is marked at a certain angle position of the same cross section, it is transported to the next marking component 4, and the angle of the next marking component 4 after swinging will be different from the marking angle of the previous marking component 4. Therefore, although the next marking component 4 also needs to be marked at the same cross section position, the angle position of the marking is different, so it is possible to achieve marking at different angles of the same cross section. In subsequent observations, clear marks representing different defects can be obtained with a greater probability.

[0044] The implementation principle of this embodiment is: By integrating multiple detection components 2 on one detection line, and realizing flexible layout and adjustment through the design of the slide 22 and the supporting wheel 23, the detection efficiency is greatly improved. At the same time, the dual-drive design of the power component 5 and the lifting function of the movable block 11 enhance the applicability and reliability of the equipment. The setting of the demagnetization component 3 solves the problem of residual magnetism generated during the flaw detection process and avoids secondary damage caused by residual magnetism. The introduction of the lifting platform 21 realizes the height adjustability of the detection component 2, so that the non-destructive testing equipment can better adapt to different types of workpieces and improve the accuracy and reliability of detection. Finally, by setting multiple marking components 4 at the end of the detection line, it is possible to accurately mark the defects at various positions of the workpiece, which is helpful for subsequent quality analysis and repair work. In particular, the innovative design of multi-angle marking overcomes the problem of overlapping marks existing in traditional marking methods and improves the clarity and recognition rate of the marks.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
