Description

Technical Field

[0001] This application relates to the field of defect detection technology, and more specifically, to a device for detecting defects on metal surfaces. Background Technology

[0002] Metals are substances that have luster (i.e., strong reflection of visible light), are malleable, and are good at conducting electricity and heat. Most metallic elements on Earth exist in nature in a combined state. Metals are widely found in nature and are extremely common in daily life. They are a very important and widely used class of substances in modern industry.

[0003] Currently, after processing metal rod-shaped workpieces, a defect detection process is required on their surface. However, existing defect detection methods for metal rod-shaped workpieces have the problem that the detection location is relatively limited, making it inconvenient to perform comprehensive defect detection on their outer surface.

[0004] To address the aforementioned problems, this application provides a metal surface defect detection device. Utility Model Content

[0005] The metal surface defect detection device provided in this application adopts the following technical solution:

[0006] A metal surface defect detection device includes a main frame. I-shaped shafts are rotatably sleeved through the middle of both ends of the main frame. An upper pulley is fixedly connected to one end face of each I-shaped shaft. The upper pulleys are located outside the main frame, and a clamping cylinder is fixedly sleeved through the central cavity of both the upper pulleys and the I-shaped shafts. A clamping disc is fixedly installed on the drive end of one side of the clamping cylinder. A rotating rod is located at the lower middle of the main frame. Lower pulleys are fixedly sleeved on the outer walls of both ends of the rotating rod. The two lower pulleys are located on two upper pulleys respectively. A transmission belt is provided on the outer wall of the two lower pulleys and the upper pulley directly below the pulley. A first gear is fixedly sleeved on the outer wall of the middle part of the rotating rod. A second gear is meshed on one side of the first gear. A drive motor is connected to one end of the second gear through a rotating shaft. The outer walls on both sides of the rotating rod are embedded with grooves, and lifting blocks are rotatably sleeved on the outer walls on both sides of the rotating rod through the grooves. The tops of the two lifting blocks are fixedly connected to the outer surface of the bottom of the main frame. A detection component is provided at the upper end of the main frame.

[0007] Through the above technical solution, the side grooves and lifting blocks achieve a rotatable lifting limit for the rotating rod.

[0008] Furthermore, the main frame is a prism-shaped hollow frame structure, and support legs are fixedly installed at the four corners of the bottom of the main frame. A control panel is fixedly installed on one outer surface of the main frame, and the surface of the control panel is respectively provided with a smart display and control buttons.

[0010] Furthermore, the two clamping discs are located on both sides inside the main frame, and anti-slip rubber pads are fixedly installed on the opposite end faces of the two clamping discs.

[0011] Through the above technical solutions, the anti-slip rubber pad can improve the anti-slip effect of clamping contact with the workpiece.

[0012] Furthermore, a fixing seat is fixedly connected to the outer surface of the drive motor on the side opposite to the second gear, and the fixing seat is fixedly installed at the bottom of the main frame.

[0013] Through the above technical solution, the mounting bracket achieves the function of connecting and fixing the drive motor.

[0014] Furthermore, the detection component includes a screw rotatably mounted in the inner cavity of the upper middle part of the main frame. One end of the screw is connected to an adjustment motor, which is fixedly mounted on the outer surface of the main frame. A displacement block is screwed onto the outer wall of the screw. The displacement block is located on the inner side of the upper part of the main frame, and multiple electric push rods are fixedly mounted on the bottom of the displacement block. A detection probe is fixedly mounted on the driving end of the multiple electric push rods through a connecting plate.

[0015] Furthermore, the detection component also includes a slide rail groove located at the center of the top of the displacement block, and a slide rail strip is slidably sleeved through the inner wall of the slide rail groove, the slide rail strip being fixedly installed on the inner wall of the top of the main frame.

[0016] Through the above technical solution, the detection component can achieve close-range and defect detection of the outer surface of metal workpieces.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] The main frame in this application, along with the I-shaped shaft, upper pulley, clamping cylinder, clamping disc, rotating rod, lower pulley, transmission belt, first gear, second gear, drive motor, groove, lifting block, and detection components, facilitates clamping and positioning of metal rod-shaped workpieces while enabling rotatable, all-around defect detection of their outer surface.

[0028] Example:

[0029] This application discloses a metal surface defect detection device. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 The system includes a main frame 1. I-shaped shafts 2 are rotatably sleeved through the middle of both ends of the main frame 1. An upper pulley 3 is fixedly connected to one end of each I-shaped shaft 2. The upper pulley 3 is located outside the main frame 1, and a clamping cylinder 4 is fixedly sleeved through the central cavity of both the upper pulley 3 and the I-shaped shaft 2. A clamping disc 5 is fixedly installed on the drive end of one side of the clamping cylinder 4. A rotating rod 6 is located at the lower middle part of the main frame 1. Lower pulleys 7 are fixedly sleeved on the outer walls of both ends of the rotating rod 6. The two lower pulleys 7 are located directly below the two upper pulleys 3. Furthermore, a transmission belt 8 is provided on the outer wall of the middle part of the two lower pulleys 7 and the upper pulley 3. A first gear 9 is fixedly sleeved on the outer wall of the middle part of the rotating rod 6. A second gear 10 is meshed on one side of the first gear 9. A drive motor 11 is connected to one end of the second gear 10 through a rotating shaft. A ring groove 12 is embedded in the outer wall of both sides of the rotating rod 6. A lifting block 13 is rotatably sleeved on the outer wall of both sides of the rotating rod 6 through the ring groove 12. The top of the two lifting blocks 13 is fixedly connected to the outer surface of the bottom of the main frame 1. A detection component is provided at the upper end of the main frame 1.

[0030] The main frame 1 is a hollow prism-shaped frame structure, and support legs are fixedly installed at the four corners of the bottom of the main frame 1. A control panel 14 is fixedly installed on one outer surface of the main frame 1. The surface of the control panel 14 is equipped with a smart display and control buttons. Two clamping plates 5 are located on both sides inside the main frame 1, and anti-slip rubber pads are fixedly installed on the opposite end faces of the two clamping plates 5. A fixing seat is fixedly connected to the outer surface of the drive motor 11 on the side facing away from the second gear 10, and the fixing seat is fixedly installed at the bottom of the main frame 1.

[0031] Please see Figure 1 and Figure 4The detection assembly includes a screw 15 rotatably mounted in the inner cavity of the upper middle part of the main frame 1. One end of the screw 15 is connected to an adjusting motor 16, which is fixedly mounted on the outer surface of the main frame 1. A displacement block 17 is screwed onto the outer wall of the screw 15. The displacement block 17 is located on the inner side of the upper part of the main frame 1, and multiple electric push rods 18 are fixedly mounted on the bottom of the displacement block 17. A detection probe 19 is fixedly mounted on the driving end of the bottom of the multiple electric push rods 18 through a connecting plate. The detection assembly also includes a slide rail groove opened at the middle of the top of the displacement block 17, and a slide rail strip 20 is slidably sleeved through the inner wall of the slide rail groove. The slide rail strip 20 is fixedly mounted on the inner wall of the top of the main frame 1. The sliding cooperation between the slide rail groove and the slide rail strip 20 can realize the limiting function during the adjustment of the position of the displacement block 17.

[0032] The control panel 14 is electrically connected and controlled to the clamping cylinder 4, the drive motor 11, the adjusting motor 16, the multi-section electric push rod 18, and the detection probe 19 via wires. The connection and control functions of the control panel 14 can be implemented by programming, which is existing technology and will not be described in detail here. The detection probe 19 feeds back the images and data it detects to the control panel 14, and displays the feedback through the smart display on it.

[0033] The implementation principle of this embodiment is as follows: When in use, the metal rod-shaped workpiece is placed between two clamping plates 5. The clamping cylinders 4 on both sides drive the clamping plates 5 to stably clamp the workpiece at the center position between the two clamping plates 5. Then, the multi-section electric push rod 18 drives the detection probe 19 to approach the outer surface of the workpiece and perform defect detection. The detected images and data results are displayed on the intelligent display on the control panel 14. During the detection process, the adjustment motor 16 drives the screw 15, which indirectly causes the displacement block 17 to perform linear reciprocating motion on the outer wall of the screw 15, thereby realizing a linear detection path and range for the workpiece surface.

[0034] Furthermore, driven by the drive motor 11, the second gear 10 is engaged with the first gear 9, and the limiting rotational cooperation between the two side lifting blocks 13 and the ring groove 12 indirectly causes the rotating rod 6 to rotate slowly. At the same time, it drives the lower pulleys 7 at both ends to rotate synchronously. At this time, due to the transmission belt 8 between the lower pulleys 7 and the upper pulley 3, the I-shaped shafts 2 and the upper pulley 3 rotate synchronously, which indirectly causes the two clamping discs 5 to rotate the workpiece to adjust its position. This adjusts the position of the workpiece to be detected while ensuring the overall all-round detection function.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
