Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a metal defect detection sensing device. Background Technology

[0002] During use, metal workpieces are prone to surface defects (such as structural damage to critical parts, geometric discontinuities, etc.) due to fatigue aging or harsh environments. This leads to a significant reduction in the performance and durability of the metal workpieces. Therefore, in order to ensure the performance and durability of metal workpieces, it is necessary to detect metal surface defects. As a result, metal surface defect detection devices are being used by more and more people.

[0003] A search revealed a Chinese patent for a surface defect detection device for metal components (authorization announcement number CN210181030U), which includes a base, a top plate above the base, and several evenly distributed support rods fixedly installed between the base and the top plate. A clamping mechanism is fixedly installed on the upper surface of the base. This patented technology can achieve automatic flipping of metal components without manual operation by setting gears, grooves, and spherical pads, thus improving detection efficiency.

[0004] However, the above-mentioned device still has some drawbacks in actual use, the most obvious of which are:

[0005] 1. The mounting position of the metal defect detection device is relatively fixed, which makes it impossible to clamp metal workpieces of different sizes, thus reducing its applicability.

[0006] 2. The aforementioned metal defect detection device can only install and detect the next metal workpiece after the first one has been inspected, which requires a stop in the middle, thereby increasing the detection time and reducing the detection efficiency.

[0007] 3. The mounting base in the above-mentioned metal defect detection device can only clamp metal workpieces with specific shapes, but it is powerless to handle irregular metal workpieces. Utility Model Content

[0014] By adopting the above technical solution, the rotation of the output shaft of servo motor one can drive the rotation of the bidirectional lead screw.

[0015] In one preferred embodiment, a second servo motor is fixedly mounted on the outer side of one of the clamping plates, and the output shaft of the second servo motor passes through the clamping plate and is fixedly connected to the rotation shaft of the second rotating disk.

[0017] In a preferred embodiment, the clamping plates are all slidably connected to the inner wall of the clamping member, and the clamping member has a through groove inside for use with the servo motor.

[0018] By adopting the above technical solution, the clamping plate can play an important limiting role, making the clamping plate more stable during the adjustment process.

[0019] In a preferred embodiment, a servo motor three is embedded inside the processing table and below the rotating disk one, and the output shaft of the servo motor three is fixedly connected to the rotation shaft of the rotating disk one.

[0020] By adopting the above technical solution, the rotation of the output shaft of the servo motor three can drive the rotating disk one to rotate, thereby realizing the transmission of power.

[0022] By adopting the above technical solution and setting up a display screen, staff can view the test results.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] Reference Figure 1-3 A metal defect detection sensing device includes a processing table 1. A rotating disk 2 is rotatably mounted inside the processing table 1. Several clamping members 3 are fixedly mounted on the top of the rotating disk 2. There are six clamping members 3. Each clamping member 3 has a fixing groove 11 inside. A bidirectional lead screw 13 is rotatably connected inside each fixing groove 11. Threaded blocks 12 are threaded to both ends of the outer side of the bidirectional lead screw 13. Clamping plates 6 are fixedly connected to the outer side of each threaded block 12. A second rotating disk 7 is rotatably mounted inside each clamping plate 6. Insertion holes 8 are arranged on the adjacent side of two second rotating disks 7. Fixing posts 10 are slidably mounted inside each insertion hole 8. Springs 9 are fixedly connected between the fixing posts 10 and the inner wall of the insertion hole 8. When it is necessary to detect metal surface defects, the device can be activated by... The rotation of the rotating disk 2 rotates the metal workpiece installed in the clamping member 3 to the side facing the mounting frame 15, so that the detection component can detect surface defects of the metal workpiece. While the current metal workpiece is being detected, the second metal workpiece can be installed in the next clamping member 3 without stopping the machine in the middle, thereby improving the detection efficiency of the metal workpiece. By rotating the bidirectional lead screw 13, the threaded blocks 12 can be used to drive the two threaded blocks 12 to move in opposite directions, so that it can be used for metal workpieces of different sizes, thereby improving the applicability of the device. With the cooperation of the spring 9 and the fixed column 10, irregular metal workpieces can be clamped, so that the irregular metal workpieces can be stably placed between the two clamping plates 6.

[0034] Specifically, a detection component is provided on the top of the processing table 1. The detection component includes a mounting bracket 15 fixedly installed on the top of the processing table 1. An electromagnetic sensor 16 is fixedly installed on the side of the mounting bracket 15 near the rotating disk 2. A processor is embedded inside the mounting bracket 15. A controller 14 is fixedly installed on the outside of the processing table 1. A servo motor 4 is fixedly installed on the top of each clamping member 3. The output shaft of the servo motor 4 extends into the interior of the fixing groove 11 and is fixedly connected to the bidirectional lead screw 13. When there is a defect on the surface of the metal workpiece being tested, it will cause the magnetic flux of the electromagnetic sensor 16 to change, thereby generating an induced electromotive force in the conductor, converting the non-electrical physical quantity into an electrical signal, and transmitting the signal to the processor for processing, so as to achieve the purpose of detecting defects on the surface of the metal workpiece.

[0035] Specifically, a servo motor 2 5 is fixedly mounted on the outer side of one of the clamping plates 6. The output shaft of the servo motor 2 5 passes through the clamping plate 6 and is fixedly connected to the rotation shaft of the rotating disk 2 7. The rotation of the output shaft of the servo motor 2 5 can drive one of the rotating disks 2 7 to rotate, thereby driving the entire metal workpiece to rotate, so that the electromagnetic sensor 16 can detect the metal workpiece. The clamping plates 6 are all slidably connected to the inner wall of the clamping member 3, which can play an important limiting role for the clamping plates 6, making the clamping plates 6 relatively stable during adjustment. The clamping member 3 has a through groove inside that works with the servo motor 2 5. The inside of the processing table 1 and located in the rotating disk 2 7 is connected to the inner wall of the clamping member 3. A servo motor is embedded below the rotating disk 2. The output shaft of the servo motor is fixedly connected to the rotation shaft of the rotating disk 2. The rotation of the output shaft of the servo motor can drive the rotating disk 2 to rotate, thereby realizing the transmission of power. A display screen is fixedly installed on the side of the mounting bracket 15 away from the electromagnetic sensor 16. The display screen is set so that the staff can view the test results. The servo motor 4, servo motor 5, electromagnetic sensor 16, servo motor 3 and the display screen are all electrically connected to the controller 14. The controller 14 can control the start and stop of the servo motor 4, servo motor 5, electromagnetic sensor 16, servo motor 3 and the display screen.

[0036] Working Principle: First, when it is necessary to inspect metal surface defects, the servo motor 3 drive can be controlled by the controller 14 to drive the rotation of the rotating disk 2, rotating the metal workpiece installed in the clamping member 3 to the side facing the mounting bracket 15. While the first metal workpiece is being inspected, the second metal workpiece can be installed in the next clamping member 3. The rotation of the output shaft of the servo motor 4 drives the rotation of the bidirectional lead screw 13, thereby enabling the two threaded blocks 12 to move in opposite directions or towards each other, thus allowing for the inspection of metal workpieces of different sizes. This method allows for the use of a device without interruption, thus improving the efficiency of metal workpiece inspection. Through the combined use of spring 9 and fixing column 10, it can clamp irregular metal workpieces, ensuring their stable placement between the two clamping plates 6. When defects exist on the surface of the metal workpiece being tested, the magnetic flux of the electromagnetic sensor 16 changes, thereby generating an induced electromotive force in the conductor. This converts the non-electrical physical quantity into an electrical signal, which is then transmitted to the processor for processing. Finally, the detection result is transmitted to the display screen for the operator to view.
