Abstract
Description
Technical Field

[0002] With the widespread use of electronic products, magnetic rings are commonly used components in various electronic devices. Their quality directly affects the performance and safety of the equipment. Internal cracks are one of the main defects affecting the quality of magnetic rings.

As a result, when the detection probe is moved inside the magnetic ring for detection, it will not only cause wear on the detection probe, but also affect the accuracy of the detection results due to the debris remaining inside.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0020] Example 1: This utility model provides a magnetic ring internal crack detection machine, such as... Figures 1 to 4As shown, the device includes a base 1, a display screen 2 fixedly mounted on the top of the base 1, an electric guide rail 3 fixedly mounted on the top of the base 1 at the front position of the display screen 2, a movable block 4 fixedly connected to the top of the electric guide rail 3, a slider slidably connected inside the electric guide rail 3, the bottom end of the movable block 4 fixedly connected to the top of the slider, a detection probe 5 snapped into one end of the movable block 4, the detection probe 5 consisting of a pressure sensor and a displacement sensor, the detection probe 5 being electrically connected to the display screen 2, and a detection platform 6 fixedly mounted on the top of the base 1 at the side position of the detection probe 5, two rollers 7 rotatably connected to one end of the detection platform 6, an auxiliary motor fixedly connected to one end of each of the two rollers 7, and the bottom end of the auxiliary motor fixedly mounted inside the detection platform 6.
[0021] A motor 8 is fixedly installed at the top of the testing platform 6. A threaded rod 9 is fixedly connected to the movable end of the motor 8. A movable rod 11 is connected to the outer surface of the threaded rod 9 by thread. The bottom end of the movable rod 11 is slidably connected to the inside of the testing platform 6. A pressing rod 12 is fixedly connected to the top of the movable rod 11. A pressing plate 13 is slidably connected to the outer surface of the pressing rod 12. A positioning frame 14 is fixedly connected to the top of the testing platform 6 at the side position of the pressing rod 12.
[0022] like Figure 1 and Figure 4 As shown, a water tank 15 is movably connected to the top of the testing platform 6 below the positioning frame 14. Water is placed inside the water tank 15, and a conical plate 16 is snapped into the top of the water tank 15. Both ends of the water tank 15 are fixedly connected to the locking blocks 17, and multiple rubber balls 18 are glued to both sides of the locking blocks 17. The rubber balls 18 can increase the friction when in contact with the surface of the testing platform 6, thereby improving the stability of the water tank 15.
[0023] like Figure 1 and Figure 3 As shown, the extrusion rod 12 is tapered, with the diameter of one end of the extrusion rod 12 near the positioning frame 14 being smaller than the diameter of the other end. The center of the extrusion rod 12 is on the same horizontal line as the center of the top of the positioning frame 14. A magnetic ring is provided inside the positioning frame 14, and the diameter of the extrusion rod 12 is the same as the inner diameter of the magnetic ring. This ensures that when the extrusion rod 12 moves, it pushes the debris inside the magnetic ring to move, thereby cleaning the debris inside the magnetic ring.
[0024] like Figure 1 and Figure 3 As shown, multiple limiting blocks are fixedly connected to the inner surface of the extrusion disc 13. The limiting blocks are slidably connected to the inside of the extrusion rod 12 to prevent the extrusion disc 13 from detaching from the inside of the extrusion rod 12 when it moves. The limiting blocks play a limiting role for the extrusion disc 13.
[0025] like Figure 1 and Figure 4As shown, the top of the conical plate 16 is larger than the bottom, ensuring that debris falls along the surface into the water tank 15, thereby automating the collection of debris.
[0026] like Figure 1 and Figure 4 As shown, both sides of one end of the locking block 17 are beveled to reduce the resistance when it contacts the testing table 6, making it easier for the locking block 17 to smoothly engage with the inside of the testing table 6, thereby improving the installation efficiency of the water tank 15.
[0027] Working Principle: In actual use, the magnetic ring to be tested is first placed inside the positioning frame 14. Then, the motor 8 is started. The output end of the motor 8 rotates, driving the threaded rod 9 to rotate synchronously. The rotation of the threaded rod 9 drives the movable rod 11 to move. The movement of the movable rod 11 drives the pressing rod 12 to move synchronously. The movement of the pressing rod 12 drives the pressing disc 13 to move synchronously. As the pressing disc 13 moves, it contacts and presses the magnetic ring, thus limiting the magnetic ring. Since the pressing disc 13 is slidably connected inside the pressing rod 12, the pressing rod 12 continues to move and enters the magnetic ring. Because the diameter of the pressing rod 12 is the same as the diameter of the magnetic ring's interior, the pressing rod 12 pushes the magnetic ring inside... As the extrusion rod 12 continues to move, the debris is pushed out of the magnetic ring. Then, the magnetic ring is placed between the two rollers 7. The electric guide rail 3 drives the movable block 4 to move, and the movable block 4 drives the detection probe 5 to move. The detection probe 5 moves into the magnetic ring, and the auxiliary motor is started. The auxiliary motor drives the roller 7 to rotate, and the roller 7 drives the magnetic ring to rotate synchronously. Then, the pressure sensor and displacement sensor transmit the collected data to the display screen 2, thereby completing the internal crack detection of the magnetic ring. This can effectively achieve pre-cleaning of the inside of the magnetic ring, avoid wear of the detection probe 5 when it is moved into the inside of the magnetic ring for detection, and ensure that no debris remains inside the magnetic ring, thus ensuring the accuracy of the detection results.
[0028] The ejected debris then falls downwards and lands on the top surface of the conical plate 16. Since the top of the conical plate 16 is larger than the bottom, the debris moves upwards along the surface of the conical plate 16 and then falls into the water tank 15, completing the collection. When the water tank 15 needs to be cleaned, it is pulled upwards. The water tank 15 drives the locking block 17 to move synchronously, and the movement of the locking block 17 drives the rubber ball 18 to move synchronously. As the water tank 15 moves, when the rubber ball 18 is no longer in contact with the detection table 6, the water tank 15 is pulled out. This effectively collects the debris, facilitates centralized cleaning of the debris, and effectively improves the collection efficiency of the debris, thereby improving the cleaning efficiency of the debris.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
