Description

Technical Field

[0001] The present invention relates to the technical field of metal material detection, and particularly relates to a device for detecting deformation cracks of metal materials. Background Art

[0002] Metal materials refer to a class of engineering materials with high strength, good thermal conductivity, electrical conductivity, and ductility, and are widely used in fields such as aerospace, automobile manufacturing, construction engineering, and mechanical equipment. Since they play a crucial role in various structural components and load-bearing parts, their mechanical properties and structural integrity are of vital importance to the safety and reliability of the entire system. During production, processing, and use, metal materials may develop cracks or deform due to factors such as stress concentration, fatigue loads, and corrosive environments. If not detected and addressed in a timely manner, it is extremely likely to trigger serious safety accidents. Therefore, high-precision detection of deformation and cracks in metal materials is an important means to ensure product quality and the safe operation of equipment.

[0003] A prior utility model patent CN218036570U discloses an auxiliary device for detecting deformation cracks of metal materials, including a detector main body, a probe, a base, a motor, an adjusting screw, a fixing plate, a pushing block, and other structures; the motor drives the adjusting screw to drive the pushing block to push the stainless steel pipe to slide along the inner side of the probe, realizing automatic feeding, avoiding the low efficiency and fatigue problems caused by manual operation, and improving the detection efficiency. At the same time, under the action of the first electric telescopic rod, the end of the steel pipe can be pushed out of the probe to prevent jamming. However, there are still the following prominent problems in the actual application process:

[0004] During the process of pushing the steel pipe to move, there is no effective supporting structure for the middle part of the steel pipe. For a relatively long steel pipe, its middle part is prone to bending and sinking under the action of gravity, and the pushing structure will further exacerbate this deformation under the continuous application of thrust, resulting in a non-primitive bending change of the steel pipe during the detection process; secondly, the deformation caused by the combined action of gravity and thrust will affect the true detection result of the probe on the steel pipe body, causing misjudgment or missed detection, and reducing the accuracy and reliability of the detection data; thirdly, under the long-term stress state, it may also cause scratches on the surface of the steel pipe or damage to its internal structure, thereby affecting its subsequent use performance.

[0005] Therefore, in view of the deficiencies in the prior art, we urgently need a metal material deformation crack detection device to solve this problem. On the basis of realizing automatic feeding and precise flaw detection, this device should be equipped with a support adjustment structure for the middle part of the steel pipe to effectively prevent deformation interference caused by gravity during the detection process, improve the stability and data accuracy of the detection process, and have the advantages of reasonable structure, convenient operation, and strong adaptability, so as to significantly improve the quality and efficiency of metal material detection and better meet the high standards of non-destructive testing of metal components in modern industry. Summary of the Invention

[0006] The object of the present invention is to provide a metal material deformation crack detection device, which solves the problem that there is no effective supporting structure for the middle part of the steel pipe in the prior art during the process of pushing the steel pipe to move.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] An installation chamber is opened on one side of the top of the base, and a material receiving component is arranged on the other side of the top. The top of the installation chamber is detachably connected with a top cover. A moving groove is opened on the top of the top cover. A moving plate is slidably connected to one side of the inner part of the moving groove, and a plurality of moving frames are slidably connected to the other side of the inner part. The top of the moving frame is connected with a supporting plate through a vertical adjusting structure. A horizontal moving module cooperating with the bottom end of the moving plate is connected inside the installation chamber;

[0010] A sleeve is connected to the top of one side of the moving plate, and a pushing cylinder is connected to the top of the other side. A pushing plate is arranged inside the sleeve, and the output end of the pushing cylinder is connected to the pushing plate.

[0011] Among them, the material receiving component includes a horizontal material receiving plate connected to the top of the base and a collection bin arranged at the bottom of one side of the base. The collection bin and the horizontal material receiving plate are connected through an inclined material guiding plate.

[0012] Among them, the horizontal moving module includes a lead screw rotatably connected inside the installation chamber and a driving motor installed on one side of the base. The output shaft of the driving motor is in transmission cooperation with the end of the lead screw, and the moving plate is in threaded cooperation with the lead screw.

[0013] Among them, a support frame is connected to the bottom of the collection bin, and a mounting frame fixed to the bottom of the horizontal material receiving plate and connected to the top of the base is provided.

[0014] Among them, a guiding track is connected to the bottom of the inner cavity of the installation chamber, and a sliding rod with one end connected to the moving plate is slidably connected to the top of the guiding track.

[0015] Among them, sliding grooves are formed on both inner walls of the moving groove, and sliding plates that are slidably matched with the sliding grooves are fixedly connected to both sides of the bottom of the moving frame.

[0016] Among them, guiding rods are connected to both sides of the top of the top cover, sliding sleeves are connected to the top of both sides of the moving frame through connecting plates, and the sliding sleeves are slidably matched with the guiding rods.

Secondly, the device adopts the method of using the moving plate driven by the horizontal moving module to cooperate with the pushing cylinder to realize the segmented feeding of the steel pipe. In the initial stage, the whole is driven forward by the moving plate, and in the later stage, the pushing cylinder completes the final pushing task. This structural design not only improves the stability of the pushing process but also reduces the risk of mechanical wear caused by a single mechanism bearing a large thrust for a long time, extending the service life of the equipment. Thirdly, the continuous supporting effect of the supporting plate can effectively reduce the local stress concentration problem borne by the steel pipe during the pushing process, avoid surface scratches and internal structure damage, and ensure the integrity of the steel pipe to be detected.

Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1-7 As shown, a metal material deformation crack detection device in this embodiment includes a base 6, a detector main body 1 installed on one side of the base 6, and a flaw detection module 3 connected to the center of the top of the base 6. The top of the detector main body 1 is connected with a display module 2. The input end of the detector main body 1 is connected to the flaw detection module 3, and the output end is connected to the display module 2;

[0032] On one side of the top of the base 6, an installation chamber 14 is provided. On the other side of the top, a material receiving component is arranged. The top of the installation chamber 14 is detachably connected with a top cover 5. On the top of the top cover 5, a moving groove 7 is provided. On one side inside the moving groove 7, a moving plate 4 is slidably connected. On the other side inside, a plurality of moving frames 13 are slidably connected. The top of the moving frame 13 is connected with a supporting plate 12 through a vertical adjusting structure. Inside the installation chamber 14, a horizontal moving module is connected which cooperates with the bottom end of the moving plate 4.

[0033] On one side of the top of the moving plate 4, a sleeve 17 is connected. On the other side of the top, a pushing air cylinder 16 is connected. Inside the sleeve 17, a pushing plate is arranged. The output end of the pushing air cylinder 16 is connected with the pushing plate.

[0034] First, one end of the steel pipe 11 to be detected is inserted into the sleeve 17 arranged on the moving plate 4. The sleeve 17 preliminarily limits the steel pipe 11 to prevent it from shifting during the subsequent pushing process. Subsequently, the operator adjusts the height position of the supporting plate 12 by using the vertical adjusting structure according to the diameter and length of the steel pipe 11, so that the bottom of the supporting plate 12 can be in close contact with the lower side of the outer wall of the steel pipe 11 and form an effective support, thereby avoiding the phenomenon that the middle part of the steel pipe 11 bends and sinks due to its own weight. After the adjustment is completed, the horizontal moving module installed inside the base 6 is started. This module drives the moving plate 4 to slide along the direction of the moving groove 7 towards the flaw detection module 3 side, and then pushes the steel pipe 11 to move forward. As the steel pipe 11 gradually enters the flaw detection module 3, a plurality of moving frames 13 distributed on the other side of the moving groove 7 will successively be in close contact with the moving plate 4 and move forward synchronously to realize the continuous transition between multiple supporting points, ensuring that the steel pipe 11 is always evenly supported during the whole detection process. When the moving plate 4 reaches the limit position, the pushing air cylinder 16 starts to act. The pushing plate connected to its output end extends out of the sleeve 17 and continues to push the steel pipe 11 completely into the flaw detection module 3 to complete the final flaw detection. After the detection is completed, the flaw detection module 3 transmits the detection data to the detector main body 1, and the control display module 2 displays the detection result in real time; at the same time, the steel pipe 11 is pushed out from the other end of the flaw detection module 3 and falls into the material receiving component arranged on the other side of the top of the base 6 to complete the whole detection cycle.

[0035] Embodiment 2

[0036] Please refer to Figures 1-7As shown, in this embodiment, a metal material deformation crack detection device, the material receiving assembly includes a horizontal material receiving plate 8 connected to the top of the base 6 and a collection bin 10 arranged at the bottom of one side of the base 6, and the collection bin 10 and the horizontal material receiving plate 8 are connected by an inclined material guide plate 9. Specifically, through the arrangement of the horizontal material receiving plate 8, the inclined material guide plate 9 and the collection bin 10, when the steel pipe 11 completes the detection, it is first pushed out to the horizontal material receiving plate 8, and then slides into the collection bin 10 along the inclined material guide plate 9. This process ensures that the steel pipe 11 can be safely and orderly removed from the detection device and stored in a centralized manner, achieving the effect of improving work efficiency, reducing the workload of manual handling, and reducing operational risks.

[0037] The bottom of the collecting bin 10 is connected to a support frame, and the bottom of the horizontal receiving plate 8 is fixedly connected to a mounting frame connected to the top of the base 6 .

[0038] The two inner walls of the movable groove 7 are provided with sliding grooves 27, and the two sides of the bottom of the movable frame 13 are fixedly connected with sliding plates 24 that slide with the sliding grooves 27. Specifically, through the cooperation between the sliding grooves 27 and the sliding plates 24, the movable frame 13 can slide smoothly in the movable groove 7, and because the sliding plates 24 are fixed on both sides of the bottom of the movable frame 13, the stability during the sliding process is increased, and the displacement deviation caused by vibration or impact is prevented, thereby achieving the effect of enhancing the overall structural stability and improving the service life of the equipment.

[0039] Guide rods 25 are connected to both sides of the top of the top cover 5, and sliding sleeves 21 are connected to the tops of both sides of the moving frame 13 through connecting plates 26. The sliding sleeves 21 are slidably matched with the guide rods 25. Specifically, through the cooperation between the guide rods 25 and the sliding sleeves 21, the connecting plates 26 connect the sliding sleeves 21 with the moving frame 13, so that the moving frame 13 is guided by the guide rods 25 when moving, further ensuring that the continuous transition between multiple supporting points is smoother, reducing the shaking that may be caused when the steel pipe 11 switches between different supporting points, and achieving the effect of improving the support stability of the steel pipe.

[0040] The vertical adjustment structure includes an adjusting screw 22 arranged inside the moving frame 13, one end of the adjusting screw 22 is threaded through the moving frame 13 and rotatably connected to the bottom of the supporting plate 12, one side of the adjusting screw 22 is provided with a round rod 23 with one end connected to the bottom of the supporting plate 12, one end of the round rod 23 slides through the top of the moving frame 13, specifically, by setting the adjusting screw 22 and the round rod 23, the height of the supporting plate 12 is adjusted according to the specific size of the steel pipe 11, wherein the adjusting screw 22 is used to adjust the height, and the round rod 23 ensures that the supporting plate 12 does not rotate during the up and down movement, ensuring that each supporting point can provide stable support, thereby achieving the effect of adapting to the detection needs of steel pipes of different specifications and improving detection flexibility.

[0041] Embodiment 3

[0042] Please refer to Figures 1-7 As shown, a metal material deformation crack detection device according to this embodiment. The horizontal movement module includes a lead screw 19 rotatably connected inside the installation chamber 14 and a driving motor 15 installed on one side of the base 6. The output shaft of the driving motor 15 is in transmission cooperation with the end of the lead screw 19, and the moving plate 4 is in threaded cooperation with the lead screw 19. Specifically, through the cooperation of the lead screw 19 and the driving motor 15, when the driving motor 15 is started, its output shaft drives the lead screw 19 to rotate, causing the moving plate 4 to translate along the direction of the lead screw 19, realizing the automatic feeding of the steel pipe 11. This structural design not only improves the stability and accuracy of the equipment operation, but also significantly reduces the labor cost, achieving the purpose of improving the automation degree of the entire detection process.

[0043] The bottom of the inner cavity of the installation chamber 14 is connected with a guide rail 18, and the top of the guide rail 18 is slidably connected with a sliding rod 20 with one end connected to the moving plate 4. Specifically, through the cooperation of the guide rail 18 and the sliding rod 20, during the horizontal movement of the moving plate 4, the sliding rod 20 slides on the guide rail 18, ensuring the linear motion accuracy of the moving plate 4 and avoiding the problem of inaccurate position of the steel pipe 11 caused by deviation, achieving the effect of improving the positioning accuracy of the steel pipe and ensuring the detection quality.

[0044] This solution has the following working process:

[0045] A metal material deformation crack detection device provided by the present invention has the following working process: First, one end of the steel pipe 11 to be detected is inserted into the sleeve 17 provided on the moving plate 4, and the steel pipe 11 is preliminarily limited by the sleeve 17 to prevent it from shifting during the subsequent pushing process. Subsequently, the operator adjusts the height position of the supporting plate 12 according to the specific dimensions of the steel pipe 11, such as diameter and length, by using the adjusting screw 22 and the round rod 23 in the vertical adjusting structure, so that the bottom of the supporting plate 12 can be in close contact with the lower side of the outer wall of the steel pipe 11 and form an effective support, thereby avoiding the phenomenon that the middle of the steel pipe 11 bends and sinks due to its own weight. After the adjustment is completed, the driving motor 15 is started, and its output shaft drives the lead screw 19 to rotate, so that the moving plate 4 slides towards the flaw detection module 3 along the direction of the lead screw 19. During this process, the sliding rod 20 slides synchronously on the guiding track 18 to ensure the linear motion accuracy of the moving plate 4 and reduce the offset error. When the moving plate 4 drives the steel pipe 11 forward and enters the flaw detection module 3, several moving frames 13 are successively in close contact with the moving plate 4 and move forward synchronously under the cooperation of the sliding plate 24 and the sliding groove 27, realizing the continuous transition between multiple supporting points and ensuring that the steel pipe 11 is always evenly supported during the whole detection process. When the moving plate 4 reaches the limit position, the pushing cylinder 16 starts to act, and the pushing plate connected to its output end extends out of the sleeve 17 to continue to push the steel pipe 11 completely into the flaw detection module 3 to complete the final flaw detection. The detection data is transmitted from the flaw detection module 3 to the main body 1 of the detector, and the detection result is displayed in real time by the display module 2. After the detection is completed, the steel pipe 11 is pushed out from the other end of the flaw detection module 3 and falls into the receiving component, which includes a horizontal receiving plate 8, an inclined guiding plate 9 and a collecting bin 10. Among them, the steel pipe 11 first falls on the horizontal receiving plate 8 and then slides into the collecting bin 10 along the inclined guiding plate 9 to achieve orderly collection. In addition, the collecting bin 10 is kept stable by the support frame at the bottom, and the horizontal receiving plate 8 is fixed to the top of the base 6 through the mounting frame to enhance the overall structural strength. During the whole process, the moving frame 13 slides in the moving groove 7 of the top cover 5, and its two top sides are connected to the sliding sleeve 21 through the connecting plate 26 and are slidably matched with the guiding rod 25, further improving the smoothness of the moving process.

[0046] Compared with the prior art, the metal material deformation crack detection device provided by the present invention has the following remarkable beneficial effects: First, through the setting of the vertical adjustment structure composed of the moving frame 13, the supporting plate 12, the adjusting screw 22, the round rod 23, etc., the supporting height can be flexibly adjusted according to the sizes of steel pipes 11 of different specifications, so that the steel pipe 11 always maintains a stable supporting state during the detection process, solving the problem that the steel pipe 11 bends and deforms under the influence of gravity due to the lack of middle support in the traditional detection device, thereby avoiding the misdetection or missed detection phenomenon caused by deformation and improving the accuracy and reliability of the detection results. Second, through the cooperation of the lead screw 19 and the driving motor 15, the automatic feeding of the steel pipe 11 is realized, improving the stability and control accuracy of the equipment operation, reducing the labor cost, and enhancing the degree of automation. Third, the cooperation of the guiding track 18 and the sliding rod 20 ensures the linear movement track of the moving plate 4, improving the positioning accuracy of the steel pipe 11 and guaranteeing the detection quality. At the same time, the cooperation of the sliding groove 27 and the sliding plate 24 enables the moving frame 13 to smoothly slide in the moving groove 7, enhancing the structural stability, preventing the displacement deviation caused by vibration or impact, and extending the service life of the equipment. In addition, the cooperation of the guiding rod 25 and the sliding sleeve 21 further ensures that the continuous transition between multiple supporting points is more stable, reducing the shaking that may occur when the steel pipe 11 switches between different supporting points and improving the dynamic stability of the supporting system. Finally, through the setting of the horizontal material receiving plate 8, the inclined material guiding plate 9, and the collecting bin 10, the steel pipe 11 can safely and orderly slide down to the collecting bin 10 after the detection is completed, realizing the centralized collection of the workpieces after the detection, reducing the workload of manual handling, and improving the overall work efficiency.
