Description

Technical Field

[0001] This utility model relates to the field of magnetic attraction force detection technology, and more specifically to a mechanical and physical magnetic attraction force detection device. Background Technology

[0002] Mechanical magnetic attraction refers to the attractive or repulsive force generated between two objects due to the interaction of magnetic fields. This force originates from the magnetic moments within the objects; when at least one of the two objects is magnetic, they will generate mutual attraction or repulsion. With the continuous improvement of people's lives and the rapid development of technology, magnetic materials are widely used in production and daily life. A magnet is a substance or material that can generate a magnetic field, possessing the property of attracting and repelling other magnets. Magnets are generally divided into permanent magnets and soft magnets. Permanent magnets are those that can retain a high remanence for a long time in an open-circuit state, are not easily demagnetized or magnetized, and common permanent magnets include natural magnetite (such as magnetite) and artificial magnets (such as AlNiCo alloy). Magnets have wide applications in industry, medicine, electronic products, and daily life. Currently, the method for testing the magnetic attraction force that a magnet can withstand is generally manual, which is cumbersome and inconvenient for limiting and fixing the magnet, resulting in low testing efficiency and requiring improvement.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The mechanical physical magnetic attraction force detection device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1:

[0021] like Figure 1-4As shown, a mechanical physical magnetic attraction force testing device includes a testing platform 1. A positioning mechanism 2 is provided on the top of the testing platform 1. The positioning mechanism 2 includes a limiting groove 21, which is located on the top of the testing platform 1. A bidirectional lead screw 23 is provided inside the limiting groove 21. Two L-shaped clamping plates 24 are symmetrically arranged above the testing platform 1. The bottoms of the two L-shaped clamping plates 24 are located on both sides inside the limiting groove 21. The lower parts of the interior of the two L-shaped clamping plates 24 are symmetrically threaded to the outer wall of the bidirectional lead screw 23. A first electric telescopic rod 26 is fixedly installed at the middle of the top of each of the two L-shaped clamping plates 24. The telescopic end of the first electric telescopic rod 26 extends to the upper part of the interior of the L-shaped clamping plate 24 and is fixedly connected to a pressure plate 27. A geared motor 22 is fixedly installed in the middle of the left side of the platform 1. The output end of the geared motor 22 extends into the interior of the limiting groove 21 and is fixedly connected to the left end of the bidirectional lead screw 23. The right end of the bidirectional lead screw 23 is rotatably installed on the right side of the inner wall of the limiting groove 21 through a bearing. Two guide rods 25 are symmetrically fixedly installed inside the limiting groove 21. The lower part of the interior of the two L-shaped clamps 24 is slidably connected to the outer wall of the two guide rods 25. A placement plate 28 is fixedly connected in the middle of the upper part of the inner wall of the limiting groove 21. A magnet 15 is placed on the top of the detection platform 1. The bottom of the magnet 15 is located above the placement plate 28. The two sides of the magnet 15 are located between the two L-shaped clamps 24. The iron detection block 10 is located directly above the magnet 15.

[0022] In this embodiment, the geared motor 22 and the bidirectional lead screw 23 facilitate the relative movement of the two L-shaped clamping plates 24. The two guide rods 25 facilitate the downward guidance of the two L-shaped clamping plates 24, which can clamp the two L-shaped clamping plates 24 on both sides of the magnet 15. The electric telescopic rod 26 at the top of the two L-shaped clamping plates 24 facilitates the vertical movement of the pressure plate 27, which can press the two pressure plates 27 down on both sides of the top of the magnet 15, thereby further limiting and fixing the magnet 15 and increasing the stability of the magnet 15 during subsequent magnetic attraction force detection.

[0023] Example 2:

[0024] like Figure 1-4As shown, a top plate 4 is provided above the testing platform 1. Support frames 3 are fixedly installed at the four corners of the bottom of the top plate 4. The bottom ends of the support frames 3 are fixedly connected to the top of the testing platform 1. A mounting plate 6 is provided below the top plate 4. A second electric telescopic rod 5 is fixedly installed in the middle of the top of the top of the top plate 4. The telescopic end of the second electric telescopic rod 5 extends to the bottom of the top plate 4 and is fixedly connected to the middle of the top of the mounting plate 6. A tension sensor 7 is fixedly installed at the bottom of the mounting plate 6. A mounting cover 9 is provided below the tension sensor 7. A connecting frame 8 is fixedly installed at the detection end of the tension sensor 7. The bottom of the connecting frame 8 is fixedly connected to... The iron detection block 10 is located below the mounting cover 9 and is attached to the top of the mounting cover 9. The upper part of the outer wall of the iron detection block 10 is threaded into the inside of the mounting cover 9. The mounting cover 9 has a through-hole 11 in the middle. A bolt 12 is fixedly installed in the middle of the top of the iron detection block 10. The top of the bolt 12 passes through the through-hole 11 and extends to the top of the mounting cover 9. A nut 13 is threadedly connected to the upper part of the outer wall of the bolt 12. The bottom of the nut 13 overlaps the top of the mounting cover 9. A display 14 is fixedly installed on the right side of the top of the detection table 1. The tension sensor 7 is electrically connected to the display 14.

[0025] In this embodiment, the mounting plate 6, tension sensor 7, connecting frame 8, mounting cover 9, and iron detection block 10 can be driven vertically by the second electric telescopic rod 5, causing the iron detection block 10 to be magnetically attracted to the top of the magnet 15. Then, the telescopic end of the second electric telescopic rod 5 retracts, applying an upward pulling force to the iron detection block 10. At this time, the tension sensor 7 detects the magnetic attraction force between the iron detection block 10 and the magnet 15, and transmits the detected magnetic attraction force data to the display 14, allowing the operator to understand the magnetic attraction force of the magnet 15, such as the iron detection block 10. When replacement is required, the worker first removes the nut 13 from the top of the bolt 12, then rotates the iron detection block 10 to remove it from the inside of the mounting cover 9. The iron detection block 10 can then be disassembled. The new iron detection block 10 is then screwed into the inside of the mounting cover 9, so that the bolt 12 at the top of the iron detection block 10 passes through the through-hole 11 and extends to the top of the mounting cover 9. The nut 13 is then screwed into the top of the outer wall of the bolt 12, and the bottom of the nut 13 is pressed down on the top of the mounting cover 9 to fix the iron detection block 10 in place.

[0026] In summary, as Figure 1-4As shown, this mechanical physical magnetic attraction force testing device, in use, first places the magnet 15 to be tested above the placement plate 28, then drives the bidirectional lead screw 23 to rotate through the reduction motor 22, and the bidirectional lead screw 23 drives two L-shaped clamping plates 24 to slide symmetrically on the outer wall of the guide rod 25, which can clamp the two L-shaped clamping plates 24 on both sides of the magnet 15. Then, the first electric telescopic rod 26 at the top of the two L-shaped clamping plates 24 drives the pressure plate 27 to move downward, which can press the two pressure plates 27 down on both sides of the top of the magnet 15, thereby fixing the magnet 15. Then, through the second... The telescopic end of the second electric telescopic rod 5 drives the mounting plate 6, tension sensor 7, connecting bracket 8, mounting cover 9, and iron detection block 10 to move downwards, causing the iron detection block 10 to be magnetically attracted to the magnet 15. Then, the telescopic end of the second electric telescopic rod 5 retracts, applying an upward pulling force to the iron detection block 10. Since the iron detection block 10 and the magnet 15 are magnetically attracted together, the tension sensor 7 detects the magnetic attraction force between the iron detection block 10 and the magnet 15 and transmits the detected magnetic attraction force data to the display 14, thereby detecting the magnetic attraction force of the magnet 15.
