Description

Technical Field

[0001] This invention relates to the field of round steel bending detection technology, and more particularly to a round steel bending detection device. Background Technology

[0002] Round steel, as an important basic industrial material, is widely used in construction, machinery manufacturing, rail transportation, and large equipment. Its straightness (or curvature) is one of the key indicators for measuring product quality. Round steel with excessive curvature will directly affect the subsequent processing accuracy, structural strength, and assembly performance. For example, in high-speed rotating shaft parts or long-span support structures, even a small bend can lead to increased vibration, excessive wear, or even failure and breakage, posing serious safety hazards.

[0003] Currently, in the production and manufacturing of round steel (such as rolling and straightening) and the quality inspection upon warehousing, the detection of curvature mainly relies on the following traditional methods:

[0004] Manual visual inspection and contact measurement: Operators observe with the naked eye or use simple tools such as straightedges and feeler gauges for contact measurement. This method is highly dependent on the worker's experience and skill level, is subjective, has low inspection efficiency, and cannot inspect round steel bars that are moving at high temperatures or speeds. Furthermore, contact measurement can scratch the product surface and cause wear and tear on the measuring tools, making it difficult to guarantee the accuracy and consistency of the measurements.

[0005] Mechanical pointer or dial indicator inspection: The round steel bar is placed on a V-block or roller support, and the curvature is estimated by rotating the bar and observing the offset between its surface and the fixed dial indicator pointer. Although this method is an improvement over purely visual inspection, it is still an offline, sampling method that requires interrupting the production process and cannot achieve 100% full inspection. Its measurement accuracy is limited by the inertia of the mechanical structure and human reading errors, and the inspection speed is slow and labor-intensive, making it unsuitable for modern continuous, high-speed production lines.

[0006] In summary, existing technologies suffer from prominent problems such as low automation and mismatch between testing efficiency and production cycle. Therefore, there is an urgent need in this field for a round steel bending degree testing device to overcome the shortcomings of the existing technologies and meet the stringent quality control requirements of modern intelligent manufacturing.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1-8 As shown, the present invention has the following specific embodiments.

[0043] Example 1: A round steel bending degree detection device includes a base 1, with frames 2 fixedly connected to both sides of the upper end of the base 1, and a body 3 fixedly connected to the upper end of the frames 2. A centering adjustment plate 5 is provided on both the left and right sides of the frames 2. A feeding component 7 is provided at the middle position of the upper end of the base 1. Support components 10 are provided at the four corners inside the body 3, and a pressing component 11 is provided above the corresponding support components 10. A guide rail 30 is fixedly connected to the middle position of the upper end inside the body 3. A detection component 12 is provided at the bottom end of the guide rail 30. The detection component 12 includes a linear motor 61, a laser detection head 64, and a high-speed camera 65. An operation panel 13 is provided at one end of the front side of the body 3. A material port 27 is opened at the bottom end of the body 3. The linear motor 61 slides along the guide rail 30. A second electric telescopic rod 62 is fixedly connected to the bottom end of the linear motor 61. An arc plate 63 is fixedly connected to the bottom end of the second electric telescopic rod 62. The laser detection head 64 and the high-speed camera 65 are symmetrically fixedly connected to both sides of the arc plate 63.

[0044] The first adjustment component 4 is disposed between the frames 2 and is used to adjust the spacing between the centering adjustment plates 5;

[0045] Lifting component 6 is located on the upper rear side of the base 1 and is used to adjust the height of the feeding component 7.

[0046] The third adjustment component 9 is symmetrically arranged on the left and right sides inside the body 3, and is used to adjust the spacing between the support components 10 and the height of the pressing component 11.

[0047] The second adjustment component 8 is located on the front and rear sides of the bottom inside the body 3 and is used to adjust the distance between the third adjustment components 9.

[0048] The cleaning component is located on the front side of the frame 2 and is used to clean the surface of the round steel to be inspected;

[0049] The power assembly is located on the side of the body 3 and the frame 2 and is used to drive the first adjustment assembly 4 and the second adjustment assembly 8.

[0050] In this embodiment, as Figures 1-4As shown, the base 1 provides overall support, while the frame 2 and body 3 constitute the main protective and installation components. Observation windows are provided on the left, right, and front sides of the body 3. These windows are made of dimmable glass, allowing for reduced light transmittance during inspection to minimize reflections on the round steel and prevent inaccurate detection. The centering adjustment plate 5 is used for initial centering of the round steel. The feeding assembly 7 is responsible for conveying the round steel. The support assembly 10 and pressing assembly 11 work together to provide stable support and pressure for the round steel, preventing it from jumping during inspection. The detection assembly 12 moves via the guide rail 30, using a linear motor 61 to drive the laser detection head 64 and high-speed camera 65 for scanning and image acquisition. The operation panel 13 provides a human-machine interface. The first, second, and third adjustment assemblies 9 and the lifting assembly 6 work together to achieve multi-dimensional adjustments. The cleaning assembly ensures the surface of the round steel is clean before inspection.

[0051] Example 2: The feeding assembly 7 includes a second support frame 55 and a fixing plate 56. The fixing plate 56 is fixedly connected to the left and right sides of the upper end of the second support frame 55. The front and rear sides of the upper end of the fixing plate 56 are fixedly connected to the second fixing seat 57. The second fixing seat 57 is rotatably connected to the second support roller 58. The connecting shaft 60 is fixedly connected between the corresponding second support rollers 58. The sixth servo motor 59 is fixedly connected to the outer side of the corresponding second fixing seat 57. The output end of the sixth servo motor 59 is fixedly connected to the corresponding second support roller 58.

[0052] The lifting assembly 6 includes a first support frame 18, a first screw 19, and a first limiting rod 20. The first support frame 18 is fixedly connected to the upper rear side of the base 1. The first screw 19 is vertically rotatably connected to the middle position inside the first support frame 18. The first limiting rod 20 is vertically fixedly connected to the left and right sides inside the first support frame 18. A first servo motor 21 is fixedly connected to the upper end of the first support frame 18. The output end of the first servo motor 21 is fixedly connected to the upper end of the first screw 19. The middle position of the rear side of the second support frame 55 is threadedly connected to the first screw 19. The two ends of the rear side of the second support frame 55 are slidably connected to the corresponding first limiting rods 20.

[0053] In this embodiment, as Figure 2 and Figure 7As shown, when the operator inputs the specifications of the round steel to be inspected through the operation panel 13, the control system calculates a corresponding ideal conveying height. The control system sends a command to the first servo motor 21. After receiving the electrical signal, the output shaft of the first servo motor 21 begins to rotate. Since the output shaft is connected to the first screw 19... The motor's rotational motion is directly transmitted to the first screw 19, causing it to rotate. This drives the feeding assembly 7 to move linearly along the vertical direction of the first limit rod 20 via the second support frame 55. The first servo motor 21, as a servo motor, has precise position control capabilities. The control system can precisely control the angle through which the first screw 19 rotates by controlling the number of rotations of the motor, and thus precisely control the moving distance of the second support frame 55. It can stop at any specified height within the stroke range, thereby achieving precise matching with the height of the internal support assembly 10 of the machine body 3. When the second support frame 55 is raised or lowered to the predetermined height, the first servo motor 21 stops rotating and remains self-locked. At this time, the top tangent of the second support roller 58 on the feeding assembly 7 is basically on the same horizontal plane as the top tangent of the first support roller 41 of the internal support assembly 10 of the machine body 3, thus completing the feeding.

[0054] Example 3: The first adjustment component 4 includes a first slide rail 34 and a first bidirectional screw 35. The first slide rail 34 is fixedly connected between the frame 2, and the first bidirectional screw 35 is rotatably connected inside the first slide rail 34. The second adjustment component 8 includes a second slide rail 31 and a second bidirectional screw 32. The second slide rail 31 is fixedly connected to the front and rear sides of the bottom of the machine body 3, and the second bidirectional screw 32 is rotatably connected inside the corresponding second slide rail 31. The bottom of the center adjustment plate 5 is slidably connected to the first slide rail 34 and threadedly connected to one side of the corresponding first bidirectional screw 35.

[0055] The support assembly 10 includes a connecting frame 40 and a first support roller 41. The first support roller 41 is rotatably connected to one side inside the connecting frame 40. The pressing assembly 11 includes a connecting plate 47 and a hydraulic shock absorber 48. The hydraulic shock absorber 48 is vertically fixedly connected to the middle position of the bottom end of the connecting plate 47. The bottom end of the hydraulic shock absorber 48 is fixedly connected to the connecting plate 47. The front and rear sides of the bottom end of the connecting plate 47 are fixedly connected to the first fixing seat 49. The pressing roller 50 is rotatably connected inside the first fixing seat 49. The outer side of the first fixing seat 49 on one side is fixedly connected to the fifth servo motor 54. The output end of the fifth servo motor 54 is fixedly connected to the corresponding pressing roller 50. One end of the pressing roller 50 is fixedly connected to the fifth sprocket 51. The corresponding fifth sprockets 51 are driven by the fourth chain 52.

[0056] The third adjustment component 9 includes a fixed frame 36, a third slide rail 37, and a fourth slide rail 42. The third slide rail 37 is horizontally fixed to the front and rear sides of the bottom inside the fixed frame 36, and the fourth slide rail 42 is vertically fixed to the front and rear sides of the upper inside the fixed frame 36. A second screw 38 is rotatably connected inside each of the third slide rails 37. A third servo motor 39 is fixedly connected to the outer side of each of the third slide rails 37. The output end of each third servo motor 39 is fixedly connected to one end of a corresponding second screw 38. The bottom end of each connecting frame 40 is slidably connected to the corresponding third slide rail 37 and threadedly connected to the corresponding second screw 38. Each slide rail 42 has a slider 53 fixedly connected to its bottom end. The slider 53 is slidably connected to the corresponding second slide rail 31 and threadedly connected to one side of the corresponding second bidirectional screw 32. Each slide rail 42 has a third screw 43 rotatably connected inside. Each third screw 43 has a fourth sprocket 44 fixedly connected to its upper end. The fourth sprockets 44 are driven by a third chain 45. Each slide rail 42 has a fourth servo motor 46 fixedly connected to its bottom end. The output end of the fourth servo motor 46 is fixedly connected to the bottom end of the corresponding third screw 43. Both ends of the connecting plate 47 are slidably connected to the corresponding fourth slide rail 42 and threadedly connected to the corresponding third screw 43.

[0057] The power assembly includes a second servo motor 33, a first sprocket 22, a second sprocket 24, and a third sprocket 26. The second servo motor 33 is fixedly connected to one end of the outer side of the body 3. The output end of the second servo motor 33 is fixedly connected to one end of the corresponding second bidirectional screw 32. The first sprocket 22 is fixedly connected to one end of the second bidirectional screw 32. The first sprockets 22 are driven by a first chain 23. The second sprocket 24 is fixedly connected to one end of the corresponding second bidirectional screw 32. The third sprocket 26 is fixedly connected to one end of the first bidirectional screw 35. The second sprocket 24 and the third sprocket 26 are driven by a second chain 25.

[0058] In this embodiment, as Figures 1-7 As shown, the first adjustment component 4: by rotating the first bidirectional screw 35, the centering adjustment plate 5 connected by threads at both ends is driven to move synchronously towards or away from each other along the first slide rail 34, so as to realize the adaptive adjustment of the width of the conveying channel;

[0059] Second adjustment component 8: By rotating the second bidirectional screw 32, the slider 53 on it is driven to move along the second slide rail 31, thereby driving the entire third adjustment component 9 and the support component 10 and pressing component 11 installed on it to move, adjusting the span between the two sets of support points to accommodate round steel of different lengths.

[0060] The third adjustment component 9 has two functions: first, horizontal adjustment: the third servo motor 39 drives the second screw 38 to rotate, which drives the connecting frame 40 and the first support roller 41 on it to move horizontally along the third slide rail 37, which is used to adjust the distance between the two support rollers at the same end to adapt to the change in the diameter of the round steel; second, vertical adjustment: the fourth servo motor 46 drives the two third screws 43 to rotate synchronously through the third chain 45 and the fourth sprocket 44, which drives the connecting plate 47 and the entire pressing component 11 to rise and fall along the fourth slide rail 42 to adjust the pressing force and adapt to round steel of different diameters.

[0061] Support and pressing assembly 11: The first support roller 41 supports the round steel, and the pressing roller 50 is driven by the fifth servo motor 54 and achieves synchronous rotation through the fifth sprocket 51 and the fourth chain 52. Under the buffer of the hydraulic shock absorber 48, it presses the round steel from above, so that it rotates stably during the inspection process and avoids scratches.

[0062] Power Components: The second servo motor 33 serves as the core power source, directly driving a second bidirectional screw 32. This power is transmitted to another second bidirectional screw 32 via the first sprocket 22 and the first chain 23, achieving synchronous rotation of the front and rear bidirectional screws. Simultaneously, power is transmitted to the first bidirectional screw 35 via the second sprocket 24, the second chain 25, and the third sprocket 26, achieving synchronous adjustment of the centering adjustment plate 5 between frames. This design efficiently drives two major adjustment systems with a single motor.

[0063] Example 4: The lower end of the machine body 3 is fixedly connected to the four corners outside the material port 27. The bottom end of the material port 27 is provided with baffles 29 on the front and rear sides. The output end of the first electric telescopic rod 28 is fixedly connected to the corresponding baffle 29.

[0064] The cleaning assembly includes an air pump 14, a connecting pipe 15, and an air supply pipe 16. The air pump 14 is fixedly connected to the outside of the corresponding frame 2, the air supply pipe 16 is fixedly connected to the upper front side of the frame 2, the connecting pipe 15 is fixedly connected to the output end of the air pump 14 and one side of the air supply pipe 16, and several nozzles 17 are fixedly connected to the air supply pipe 16.

[0065] In this embodiment, as Figures 2-3 As shown, the first electric telescopic rod 28 controls the opening and closing of the baffle 29, the air pump 14 generates compressed air, which is delivered to the air supply pipe 16 through the connecting pipe 15, and finally sprayed out by the evenly distributed nozzles 17 to blow away the dust and debris on the surface of the round steel, ensuring the accuracy of the test results.

[0066] The overall working principle of this invention is as follows:

[0067] Loading and centering: The round steel bar is placed on the second support roller 58 of the loading component 7 by a robotic arm. At the same time, the power component drives the first bidirectional screw 35 of the first adjustment component 4 to rotate, so that the centering adjustment plates 5 on both sides adjust the spacing according to the preset width to initially center and guide the round steel bar. The lifting component 6 drives the loading component 7 to lift, thereby moving the round steel bar.

[0068] Cleaning: Before entering the feed port 27, the round steel passes behind the cleaning component on the front side of the frame 2. At this time, the sixth servo motor 59 drives the corresponding second support roller 58 to rotate slowly, thereby driving the round steel on it to rotate synchronously. The air pump 14 starts and pumps air in through the connecting pipe 15. The air is sprayed out through several nozzles 17 on the air supply pipe 16. The rotation of the round steel ensures that its entire outer surface can be evenly swept by the airflow 360°, effectively removing dust, oxide scale, coolant and other impurities attached to the surface, preparing for subsequent high-precision optical inspection and avoiding inspection errors caused by local stains.

[0069] Conveying and Positioning: After cleaning, the first electric telescopic rod 28 drives the baffle 29 to move to both sides, opening the feed port 27. The round steel is then fed into the machine body 3 through the feed port 27 and is received by the first support roller 41 of the support component 10 inside. Specifically, the second bidirectional screw 32 of the second adjustment component 8 can be driven to rotate by the power component, driving the third adjustment components 9 on both sides to move along the second slide rail 31, adjusting the distance between the two pairs of first support rollers 41 to accommodate the length of the round steel. Then, the third servo motor 39 in the third adjustment component 9 drives the second screw 38 to rotate, adjusting the distance between the corresponding first support rollers 41 to accommodate the diameter of the round steel, ensuring that the round steel is stably supported in the center position. After the round steel is placed on the first support roller 41, the feeding component 7 descends, and the baffle 29 closes the feed port 27 under the drive of the first electric telescopic rod 28.

[0070] Pressing and Rotation: After the round steel is positioned, the fourth servo motor 46 in the third adjustment component 9 drives the corresponding third screw 43 to rotate. Through the transmission of the fourth sprocket 44 and the third chain 45, it can drive another third screw 43 to rotate, thereby driving the pressing component 11 to descend along the fourth slide rail 42 through the connecting plate 47 until the pressing roller 50 contacts the upper surface of the round steel. The hydraulic shock absorber 48 provides buffering and maintains a constant pressing force. Subsequently, the fifth servo motor 54 starts and drives all pressing rollers 50 to rotate synchronously through the transmission of the fifth sprocket 51 and the fourth chain 52. The friction force drives the round steel to rotate at a constant speed on its first support roller 41. The rotation here is to allow the detection component 12 to scan its entire surface.

[0071] Inspection: While the round steel rotates at a constant speed, the inspection component 12 starts to work. The linear motor 61 moves along the guide rail 30, so that the laser inspection head 64 and the high-speed camera 65 traverse the entire length of the round steel. The second electric telescopic rod 62 can finely adjust the inspection height. The arc plate 63 ensures that the sensor faces the center of the round steel. The laser inspection head 64 scans and acquires the straightness data of the round steel generatrix. The high-speed camera 65 simultaneously captures surface images to assist in analysis. The bending value of the round steel is calculated comprehensively.

[0072] Material feeding: After the inspection is completed, the pressing component 11 is raised, and the material port 27 is opened under the drive of the first electric telescopic rod 28. The feeding component 7 rises to lift the round steel. The third servo motor 39 drives the second screw 38 to rotate, which increases the distance between the corresponding first support rollers 41, making it easier to feed the round steel.

[0073] Adjustment and Adaptation: Throughout the process, operators can set the round steel specification parameters through the operation panel 13. The equipment automatically controls each servo motor and electric telescopic rod to complete all necessary adjustments, enabling rapid switching and testing of round steel of different specifications.
