Description

Technical Field

[0001] This utility model belongs to the field of neodymium iron boron magnet testing technology, and in particular relates to a neodymium iron boron magnet testing device with a positioning structure. Background Technology

[0002] Neodymium iron boron (NdFeB) magnet testing is a systematic process of detecting and evaluating the magnetic properties, physical characteristics, environmental adaptability, and appearance quality of NdFeB permanent magnet materials. Currently, a fluxmeter is commonly used to test NdFeB magnets. A fluxmeter is an instrument that uses the principle of electronic integration to detect the number of magnetic lines passing through the coil in a space, i.e., the overall magnetic flux. It can test magnetic materials, not only measuring magnetic flux values ​​but also directly testing the performance of magnetic products, thereby achieving the purpose of controlling product quality. The fluxmeter has a peak hold function, which can quantitatively acquire instantaneous pulse magnetic fields, thereby detecting the magnitude of the pulse magnetic field.

[0003] Currently, magnetometers are typically used in conjunction with flux coils. When testing neodymium iron boron (NdFeB) magnets, the magnet to be tested is placed on the testing platform of the flux coil. The magnetic field induction area of ​​the flux coil is symmetrically distributed with respect to the geometric center of the coil. If the magnet is placed off-center (e.g., offset or tilted), the number of magnetic lines passing through the coil will decrease, or only part of the magnetic field will be captured by the coil, directly causing the measured value to be too small or distorted. Therefore, a NdFeB magnet testing device with a positioning structure is needed. The NdFeB magnet to be tested can be placed in the center through the centering positioning structure, thereby ensuring the accuracy of the NdFeB magnet test. Utility Model Content

[0004] The purpose of this invention is to provide a neodymium iron boron magnet testing device with a positioning structure, which can center and place the neodymium iron boron magnet to be tested through the centering positioning structure, thereby ensuring the accuracy of the neodymium iron boron magnet test and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A neodymium iron boron magnet testing device with a positioning structure includes a fluxmeter instrument: a flux coil assembly is provided on the right side of the fluxmeter instrument, the flux coil assembly is electrically connected to the fluxmeter instrument, a U-shaped support plate is fixedly connected to the inner cavity of the flux coil assembly, a mounting plate is fixedly connected to the bottom of the U-shaped support plate, two connecting plates are provided at the bottom of the mounting plate, four limiting slide rails are fixedly installed at the bottom of the mounting plate, two symmetrical limiting sliders are fixedly installed at the top of the connecting plates, the limiting sliders are slidably connected to the limiting slide rails, two symmetrical fixing blocks are fixedly connected to the top of the connecting plates, positioning elements are fixedly installed on the surface of the fixing blocks, a connecting rod one is rotatably connected to the bottom of the mounting plate, two connecting rod two are rotatably connected to the surface of the connecting rod one, the connecting rod two are rotatably connected to the connecting plate, a cylinder is fixedly installed at the bottom of the mounting plate, and the output end of the cylinder is fixedly connected to one of the connecting plates.

[0006] Preferably, two limiting discs are mounted on the surface of the positioning member, and a neodymium iron boron magnet is placed on the top of the U-shaped support plate.

[0007] Preferably, the limiting disc is in contact with the surface of the neodymium iron boron magnet.

[0008] Preferably, the positioning element is an L-shaped positioning element, and the mounting plate is a T-shaped mounting plate.

[0009] Preferably, the surface of the magnetic flux coil assembly has four slots.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a cylinder to extend its output end first, then places the neodymium iron boron magnet on top of the U-shaped support plate, and then retracts the cylinder's output end. This causes the cylinder's output end to drive the two connecting plates to move relative to each other through the action of connecting rod one and connecting rod two. This, in turn, causes the connecting plates to drive the limiting slider to slide on the limiting slide rail surface. The two connecting plates then drive the positioning components to move through the fixing block, causing the two positioning components on the left and the two positioning components on the right to move relative to each other. This achieves the purpose of centering and positioning the neodymium iron boron magnet to be tested, thus ensuring the accuracy of the neodymium iron boron magnet test.

[0012] 2. By setting a limiting disc, when the cylinder is started, the output end of the cylinder drives the two connecting plates to move relative to each other through connecting rod one and connecting rod two. This causes the connecting plates to drive the limiting disc to clamp and position the neodymium iron boron magnet through the positioning component, thereby reducing the damage to the neodymium iron boron magnet.

[0021] In the following description, embodiments of the NdFeB magnet testing device with a positioning structure of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-5This invention illustrates a neodymium iron boron magnet testing device with a positioning structure according to an embodiment of the present invention. The device includes a fluxmeter instrument 1. A flux coil assembly 2 is disposed on the right side of the fluxmeter instrument 1. The surface of the flux coil assembly 2 has four slots. The flux coil assembly 2 is electrically connected to the fluxmeter instrument 1. A U-shaped support plate 3 is fixedly connected to the inner cavity of the flux coil assembly 2. A mounting plate 4 is fixedly connected to the bottom of the U-shaped support plate 3. Two connecting plates 5 are disposed at the bottom of the mounting plate 4. Four limiting slide rails 6 are fixedly mounted at the bottom of the mounting plate 4. Two symmetrical limiting sliders 7 are fixedly mounted on the top of the connecting plates 5. The limiting sliders 7 are slidably connected to the limiting slide rails 6. The top of the mounting plate 5 is fixedly connected to two symmetrical fixing blocks 8. The surface of the fixing blocks 8 is fixedly installed with positioning parts 9, which are L-shaped positioning parts. The mounting plate 4 is a T-shaped mounting plate. The surface of the positioning parts 9 is installed with two limiting discs 13. The top of the U-shaped support plate 3 is placed with a neodymium iron boron magnet 14. The limiting discs 13 are in contact with the surface of the neodymium iron boron magnet 14. The bottom of the mounting plate 4 is rotatably connected to a connecting rod 10. The surface of the connecting rod 10 is rotatably connected to two connecting rods 11. The connecting rods 11 are rotatably connected to the mounting plate 5. The bottom of the mounting plate 4 is fixedly installed with a cylinder 12. The output end of the cylinder 12 is fixedly connected to one of the mounting plates 5.

[0023] Working principle: When using this utility model, the user starts the cylinder 12, causing the output end of the cylinder 12 to extend first. Then, the neodymium iron boron magnet 14 is placed on top of the U-shaped support plate 3, and the output end of the cylinder 12 is retracted. This causes the output end of the cylinder 12 to drive the connecting plate 5 on its right side to move to the left. In turn, the connecting plate 5 on the right side, through the action of connecting rod 10 and connecting rod 21, drives the connecting plate 5 on the left side to move to the right. This causes the connecting plate 5 to drive the limiting slider 7 to slide on the surface of the limiting slide rail 6. At this time, the two connecting plates 5 move relative to each other, causing the two connecting plates 5 to drive the positioning parts 9 to move through the fixing block 8. This causes the two positioning parts 9 on the left side and the two positioning parts 9 on the right side to move relative to each other. This causes the positioning parts 9 to drive the limiting disc 13 on their surface to clamp and position the neodymium iron boron magnet 14. This achieves the purpose of centering and positioning the neodymium iron boron magnet to be tested through the centering and positioning structure, thereby ensuring the accuracy of the neodymium iron boron magnet test.

[0024] In summary, this NdFeB magnet testing equipment with a positioning structure works by activating cylinder 12, extending its output end, placing the NdFeB magnet 14 on top of the U-shaped support plate 3, and then retracting the output end of cylinder 12. This causes the output end of cylinder 12 to move relative to the two connecting plates 5 via connecting rod 10 and connecting rod 2, which in turn causes the connecting plates 5 to move the limiting slider 7 on the surface of the limiting rail 6. The two connecting plates 5 then move the positioning components 9 via the fixing block 8, resulting in relative movement between the two positioning components 9 on the left and the two on the right. This centering positioning structure allows the NdFeB magnet to be tested to be placed in the center, thus ensuring the accuracy of the NdFeB magnet testing.
