The lead screw pair is rotatably sleeved outside the lead screw, and the lead screw pair is slidably clamped inside the first housing. The lead screw pair is provided with an internal thread matching the lead screw. One end of the lifting rod can slidably penetrate the first housing and is fixedly connected to the lead screw pair.

This prior art belongs to the technical field of magnetic material detection, and specifically refers to a detector for the surface adhesion of magnetic materials suitable for curved and irregular magnetic materials with high detection accuracy.

[0004] However, the current adhesion detection device has the following problems: When this adhesion detection device detects a cylindrical magnetic material, due to the easy rolling displacement of the cylindrical magnetic material, it is very difficult to ensure the contact area between the detection end of the adhesion detection device and the cylindrical magnetic material. As a result, the detection is prone to errors, which is not conducive to the detection of magnetic materials. Therefore, we have proposed a device and method for detecting the surface adhesion of high-frequency magnetic materials. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device and method for detecting the surface adhesion of high-frequency magnetic materials, which solves the problem that when the adhesion detection device detects a cylindrical magnetic material, due to the easy rolling displacement of the cylindrical magnetic material, it is very difficult to ensure the contact area between the detection end of the adhesion detection device and the cylindrical magnetic material, resulting in prone errors in the detection and being not conducive to the detection of magnetic materials as mentioned in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A device for detecting the surface adhesion of a high-frequency magnetic material, including a detection table, on the top right side of the detection table, an L-shaped telescopic rod is fixed, and at the telescopic end of the L-shaped telescopic rod, a main detection device is fixed. It also includes an anti-displacement device, which includes a V-shaped box, two shaft rods, four pressing plates and spring rods. The V-shaped box is fixedly installed on the top of the detection table. The two shaft rods are respectively rotatably installed on the left and right sides of the inner wall of the V-shaped box. The two pressing plates are in a group, and one group of pressing plates are respectively fixed on the left and right sides of the outer wall of the shaft rod. A torsion spring is provided between the pressing plate and the inner wall of the V-shaped box. The spring rod passes through and is slidably installed on the top surface of the pressing plate, and a torsion spring is provided between the spring rod and the pressing plate. A roller is rotatably installed at the top of the spring rod. The elastic force of the torsion spring corresponding to the pressing plate is greater than the elastic force of the spring corresponding to the spring rod. The V-shaped opening of the V-shaped box will limit and position the cylindrical magnetic material. At the same time, under the action of the elastic force of the torsion spring corresponding to the pressing plate, the pressing plate drives the spring rod to press the cylindrical magnetic material, so that the cylindrical magnetic material is stably fixed at the V-shaped opening of the V-shaped box, thus avoiding the problem that the cylindrical magnetic material rolls and displaces during detection, resulting in detection errors.

[0007] Preferably, a rotating device is provided at the bottom of the inner wall of the V-shaped box. The rotating device includes sliders. There are two sliders, and the two sliders are respectively slidably installed on the left and right sides of the inner wall of the V-shaped box. A rotating rod is rotatably installed between the two sliders. The rotating rod is driven by an external motor. On the left and right sides of the outer wall of the rotating rod, a contact wheel is fixed. The rotating rod is driven by the motor to drive the contact wheel to rotate, and the contact wheel drives the cylindrical magnetic material to rotate, so that the detection end of the main detection device detects multiple surfaces of the cylindrical magnetic material. The rotating device also includes telescopic frames. There are two telescopic frames, and the two telescopic frames are both fixed at the bottom of the inner wall of the V-shaped box. A scraping plate is fixed between the telescopic ends of the two telescopic frames. The scraping plate is located directly above the rotating rod. At the same time, the scraping plate scrapes off the impurities adhering to the outer surface of the cylindrical magnetic material, thus avoiding the problem that the accuracy of the detection result is affected when detecting due to the surface defects of the material.

[0008] Preferably, the left and right sides of the rotating rod are provided with friction-increasing devices, and the friction-increasing devices include a spring plate and a convex ball ring. There are two spring plates, and the two spring plates are respectively fixed to the left and right sides of the bottom of the scraper plate.

There are two convex ball rings, and the two convex ball rings are respectively slidably installed on the left and right sides of the rotating rod, and a spring is provided between the convex ball ring and the contact wheel. A plurality of L-shaped rods are fixed to the outside of the convex ball ring, and the end of the L-shaped rod away from the convex ball ring penetrates and is slidably installed on the outer wall of the contact wheel A plurality of convex ball blocks are fixed on the side of the convex ball ring away from the resistance wheel, and the spring plate is located on the movement trajectory of the convex ball blocks of the convex ball ring. The convex ball ring drives the arc rod to knock the scraper by pushing the spring plate, and the scraper vibrates and shakes off the scraped impurities, thereby improving the subsequent scraper's effect of scraping impurities on the cylindrical magnetic material; at the same time, the spring plate pushes the convex ball ring to move in the direction of the resistance wheel, and the convex ball ring drives the L-shaped rod to slide on the outside of the resistance wheel and pushes off the impurities adhered to the outside of the resistance wheel, thereby avoiding the problem that the resistance wheel is covered by impurities after long-term use, affecting the rotation of the cylindrical magnetic material driven by the resistance wheel.

[0009] Preferably, an anti-adhesion device is provided on the top of the V-mouth box, and the anti-adhesion device includes an inclined frame and a fixed rod. There are two inclined frames, and the two inclined frames are respectively fixed to the front and back sides of the inner wall of the V-mouth box. A U-shaped frame is fixed on the top of the inclined frame, and the U-shaped frame limits the setting of the detection device body, thereby ensuring that the detection device body can move stably, thereby indirectly improving the accuracy of the detection result of the detection device body on the cylindrical magnetic material. Fixed rods are slidably installed on the left and right sides of the inner wall of the U-shaped frame, and the fixed rods are fixed to the outer wall of the detection device body. A cleaning brush plate is slidably installed between the bottoms of the two fixed rods, and the top surface of the cleaning brush plate contacts the bottom of the detection end of the detection device body, and at the same time, through the cleaning brush The plate blocks the detection end of the detection device main body, so that the cleaning brush plate can protect the detection end of the detection device main body, thereby avoiding the problem of accidental bumping and damage to the detection end of the detection device main body; a fixed column is fixed to the right side of the end of the cleaning brush plate away from the U-shaped frame, and the fixed column is slidably connected to the inside of the Z-shaped slot plate, and the Z-shaped slot plate is fixed to the top of the inclined frame. At the same time, each time the detection device main body moves upward, it is restricted by the Z-shaped slot of the Z-shaped slot plate, so that the fixed column drives the cleaning brush plate to move along the fixed rod in the direction close to the detection device main body, so that the cleaning brush plate cleans the detection end of the detection device main body, thereby avoiding the problem of impurities adhering to the detection end of the detection device main body, resulting in inaccurate detection results.

Limited by the Z-shaped groove of the Z-shaped groove plate 66, the fixed column 65 drives the cleaning brush plate 64 to move away from the detection device main body 3 along the fixed rod 63. When the detection device main body 3 moves upward each time, limited by the Z-shaped groove of the Z-shaped groove plate 66, the fixed column 65 drives the cleaning brush plate 64 to move toward the detection device main body 3 along the fixed rod 63, so that the cleaning brush plate 64 cleans the detection end of the detection device main body 3, thus avoiding the problem that impurities adhere to the detection end of the detection device main body 3, resulting in inaccurate detection results.
