Description

Technical Field

[0001] The present invention relates to the technical field of round steel curvature detection, and in particular to a round steel curvature detection device. Background Art

[0002] As an important basic industrial material, round steel is widely used in construction, machinery manufacturing, rail transportation, large-scale equipment, and other fields. Its straightness (or curvature) is a key indicator of product quality. Round steel with excessive curvature can directly affect subsequent processing accuracy, structural strength, and assembly performance. For example, in high-speed rotating shaft parts or long-span support structures, even slight curvature can lead to increased vibration, excessive wear, and even failure and fracture, posing a serious safety hazard.

[0003] At present, in the production and manufacturing of round steel (such as rolling and straightening) and the quality inspection of warehousing, the detection of curvature mainly relies on the following traditional methods: Manual visual inspection and contact measurement: Operators perform contact measurement through visual observation or using simple tools such as straightedges and feeler gauges. This method relies heavily on the worker's experience and skill level, is highly subjective, and has low inspection efficiency. It is also unable to inspect round steel that is hot or moving at high speeds. Furthermore, contact measurement can scratch the product surface and cause wear on the measuring tool, making it difficult to guarantee accurate and consistent measurements.

[0004] Mechanical pointer or dial indicator testing: The round steel is placed on a V-block or roller support. The curvature is estimated by rotating the steel and observing the offset between its surface and the fixed dial indicator pointer. While this method offers an improvement over purely visual inspection, it remains an offline, spot-checking method that requires interrupting the production process and cannot achieve 100% inspection. Its measurement accuracy is limited by mechanical inertia and manual reading errors. Furthermore, the testing process is slow and labor-intensive, making it unsuitable for modern, continuous, high-speed production lines.

[0005] To sum up, the existing technology mainly has prominent problems such as low degree of automation and mismatch between detection efficiency and production rhythm. Therefore, this field urgently needs a round steel bending detection equipment to overcome the defects of the above-mentioned existing technology and meet the stringent requirements of modern intelligent manufacturing for quality control.

[0023] In this embodiment, Figures 1-4 As shown, the base 1 provides overall support, the frame 2 and the body 3 constitute the protection and installation body, and the left and right sides and the front end of the body 3 are provided with observation windows.

[0027] In this embodiment, Figure 1-Figure 7 As shown, the first adjustment component 4: through the rotation of the first bidirectional screw 35, the center adjustment plate 5 connected by threads at both ends is driven to move synchronously toward or away from each other along the first slide rail 34 to achieve adaptive adjustment of the width of the conveying channel; The second adjustment assembly 8: The second bidirectional screw 32 rotates to drive the slider 53 thereon to move along the second slide rail 31, thereby driving the entire third adjustment assembly 9 and the support assembly 10 and pressing assembly 11 mounted thereon to move, adjusting the span between the two sets of support points to accommodate round steel bars of different lengths; The third adjustment assembly 9 has two functions: one is horizontal adjustment: the third servo motor 39 drives the second screw 38 to rotate, driving the connecting frame 40 and the first support roller 41 thereon 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 diameter change of the round steel; the other is 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, driving the connecting plate 47 and the entire pressing assembly 11 to move up and down along the fourth slide rail 42 to adjust the pressing force and adapt to round steels of different diameters; Support and pressing assembly 11: The first support roller 41 supports the round steel bar.

[0028] Example 4: The lower end of the body 3 is fixedly connected to the four corners outside the material opening 27 with a first electric telescopic rod 28. The front and rear sides of the bottom of the material opening 27 are provided with baffles 29. The output ends of the corresponding first electric telescopic rods 28 are fixedly connected to the corresponding baffles 29 respectively. The cleaning assembly includes an air pump 14, a connecting pipe 15 and an air pipe 16. The air pump 14 is fixedly connected to the outside of the corresponding frame 2, the air pipe 16 is fixedly connected to the upper side of the front end 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 pipe 16, and several nozzles 17 are fixedly connected to the air pipe 16.

[0029] In this embodiment, Figure 2-Figure 3 As shown, the first electric telescopic rod 28 controls the opening and closing of the baffle 29, and the air pump 14 generates compressed air, which is transported to the air 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 to ensure the accuracy of the test results.

[0030] The overall working principle of the present invention is as follows: Loading and centering: The round steel is placed on the second support roller 58 of the loading assembly 7 by a robot. Simultaneously, the power assembly drives the first bidirectional screw 35 of the first adjustment assembly 4 to rotate, so that the centering adjustment plates 5 on both sides adjust the spacing according to the preset width, providing preliminary centering and guiding for the round steel. The lifting assembly 6 drives the loading assembly 7 to lift, thereby driving the round steel to move; Cleaning: Before entering the material inlet 27, the round steel passes through the rear side of the cleaning assembly 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 is started, pumping air into the connecting pipe 15, and ejecting high-speed airflow through the multiple nozzles 17 on the air supply pipe 16. The rotation of the round steel allows its entire outer surface to be evenly swept by the airflow in 360 degrees, effectively removing impurities such as dust, oxide scale, and coolant attached to the surface, preparing for subsequent high-precision optical inspection and avoiding inspection errors caused by local stains; Conveying and positioning: After cleaning is completed, the first electric telescopic rod 28 drives the baffle 29 to move to both sides, opening the material port 27, and the round steel continues to be fed into the interior of the machine body 3 through the material port 27, and is received by the first support roller 41 of the support assembly 10 therein. Specifically, the second bidirectional screw 32 of the second adjusting assembly 8 can be driven to rotate by the power assembly, driving the third adjusting assemblies 9 on both sides to move along the second slide rail 31, adjusting the distance between the left and right pairs of first support rollers 41 to adapt to the length of the round steel. Then, the third servo motor 39 in the third adjusting assembly 9 drives the second screw 38 to rotate, adjusting the spacing between the front and rear corresponding first support rollers 41 to adapt to 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 loading assembly 7 descends, and the baffle 29 closes the material port 27 driven by the first electric telescopic rod 28; Pressing and rotation: After the round steel is positioned, the fourth servo motor 46 in the third adjustment assembly 9 drives the corresponding third screw 43 to rotate. Through the transmission of the fourth sprocket 44 and the third chain 45, the other third screw 43 can be driven to rotate, thereby driving the pressing assembly 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 is started and drives all the 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 uniform speed on its first support roller 41. The rotation here is to enable the detection assembly 12 to scan its entire surface; Detection: While the round steel rotates at a constant speed, the detection component 12 starts working, and the linear motor 61 moves along the guide rail 30, so that the laser detection head 64 and the high-speed camera 65 traverse the entire length of the round steel. The second electric telescopic rod 62 can fine-tune the detection height. The curved plate 63 ensures that the sensor is facing the center of the round steel. The laser detection head 64 scans and obtains the straightness data of the round steel busbar. The high-speed camera 65 synchronously captures the surface image for auxiliary analysis, and the curvature value of the round steel is obtained through comprehensive calculation.

[0031] Unloading: After the inspection is completed, the pressing assembly 11 is raised, and the material port 27 is opened under the drive of the first electric telescopic rod 28. The loading assembly 7 rises to lift the round steel, and the third servo motor 39 drives the second screw 38 to rotate, so that the distance between the front and rear corresponding first support rollers 41 is increased, which facilitates the unloading of the round steel.

[0032] Adjustment and adaptation: During the entire process, the operator can set the round steel specification parameters through the operation panel 13. The equipment automatically controls the servo motors and electric telescopic rods to complete all necessary adjustments and realize the rapid switching and detection of round steels of different specifications.
