Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping devices for ferrite cores, in particular to a clamping structure for detecting ferrite cores. Background Art
[0002] The inspection of ferrite cores includes appearance inspection, crystal structure inspection and thermal stability inspection. Appearance inspection and thermal stability inspection generally do not require the use of a clamping structure to limit the position of the ferrite core, while crystal structure inspection is generally used to detect the crystal structure changes of the ferrite core before and after sintering. When performing crystal structure inspection, X-ray diffraction or electron backscatter diffraction (ie: EBSD) is generally used for inspection. X-ray inspection is a grinding inspection (ie, destructive inspection). The EBSD inspection method is a non-destructive inspection method that inspects and tests the internal or surface structure, state and defects of the inspected object without destroying or affecting its performance. When using the EBSD inspection method, the core is generally placed in a corresponding inspection box (such as: EBSD inspection box), and a clamping device is used to limit the position of the ferrite core to avoid position offset during the imaging process, which causes imaging blur.
[0003] However, the clamping device used in the prior art is not universal. When testing different types of magnetic cores, the corresponding clamps need to be frequently replaced to match the operation, thereby reducing the clamping and assembly efficiency and further affecting the testing operation.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1 to Figure 3 In an embodiment of the utility model, a clamping structure for detecting a ferrite core comprises a workbench 1 installed in the middle section of an inner cavity of a detection box, a driving mechanism is installed at the top of the workbench 1, a clamping mechanism meshing with the driving mechanism is arranged above the workbench 1, and a lifting mechanism penetrating to the top of the workbench 1 is installed at the bottom of the workbench 1; the driving mechanism comprises a forward and reverse motor 2 installed at the top of the workbench 1 through a motor bracket, and a driving gear 3 is connected to the output end of the forward and reverse motor 2; the clamping mechanism comprises a rotating disk 4 located at the top of the workbench 1 and at one side of the driving gear 3, and a plurality of tooth blocks 5 are formed at equal intervals on the outer periphery of the rotating disk 4, and the driving gear 3 meshes with the tooth blocks 5.
[0018] In this embodiment: the device is installed in a detection box (such as an electron backscatter diffraction detection box used in the overall detection). First, the ferrite ring to be detected is placed on the top of the clamping mechanism, and then the driving mechanism is started. The driving mechanism drives the clamping mechanism to clamp the ferrite ring to be detected. After the clamping is stable, the lifting mechanism is started, and the lifting mechanism drives the four clamping rods 8 to move upward synchronously, thereby driving the ferrite ring to move upward. After moving upward to a certain height, the crystal structure of the ferrite ring is detected by electron backscatter diffraction. By realizing the upward movement of the ferrite ring, it can be avoided that it contacts the top of the fixed disk 6, and the image overlap occurs, which causes the problem of wrong judgment.
[0019] Please refer to Figure 1 , Figure 2 and Figure 3 The clamping mechanism also includes a fixed disk 6 rotatably installed above the rotating disk 4, the fixed disk 6 has strip grooves 7 equidistantly opened in the inner circumference, the rotating disk 4 has arc grooves 12 equidistantly opened in the inner circumference, and the strip grooves 7 and the inner walls of the arc grooves 12 are movably connected with clamping rods 8.
[0020] In this embodiment, when the driving gear 3 rotates, the driving gear 3 rotates through the gear block 5 to drive the rotating disk 4 to rotate. At this time, the arc groove 12 rotates accordingly, and the rotating arc groove 12 squeezes the clamping rod 8. The clamping rod 8 under pressure moves along the inner wall of the strip groove 7, so that the four clamping rods 8 move inward or outward synchronously, thereby meeting the purpose of clamping and fixing ferrite rings with different inner diameters.
[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The lifting mechanism includes an electric push cylinder 11 installed at the bottom end of the workbench 1 through a bracket. The piston rod of the electric push cylinder 11 extends to the top of the workbench 1. A connecting frame 15 is fixedly installed on the top of the piston rod of the electric push cylinder 11. A lifting plate 9 is fixedly installed on the top of the connecting frame 15. The inner circumference of the lifting plate 9 is equidistantly provided with sliding grooves 16 for the clamping rod 8 to slide.
[0022] In this embodiment, after the ferrite ring is clamped, the electric push cylinder 11 is started, and the electric push cylinder 11 drives the connecting frame 15 at its output end to move upward synchronously, and the connecting frame 15 drives the lifting plate 9 to move upward synchronously. During the movement of the clamping rod 8, the sliding groove 16 can provide a trajectory guide for the movement of the lower part of the clamping rod 8.
[0023] Please refer to Figure 2 and Figure 3 The outer wall of the clamping rod 8 is located at the top and bottom of the sliding groove 16 and is integrally formed with a limit plate 13, and the outer diameter of the limit plate 13 is larger than the diameter of the clamping rod 8; the outer wall of the clamping rod 8 fits well with the inner wall of the sliding groove 16.
[0024] In this embodiment: when the lifting plate 9 moves upward, the lifting plate 9 drives the four clamping rods 8 to move upward synchronously through the limit plate 13. The four clamping rods 8 that move upward synchronously can drive the clamped ferrite magnetic ring to move upward, thereby achieving the purpose of separating the ferrite magnetic ring from the top of the fixed plate 6.
[0025] Please refer to Figure 3 The lifting plate 9 has sliding holes 14 equidistantly arranged on its inner circumference, and the sliding holes 14 are located between two adjacent sliding grooves 16. The inner wall of the sliding hole 14 is slidably connected with a guide rod 10, and the bottom end of the guide rod 10 is fixedly connected to the top end of the workbench 1, and the top end of the guide rod 10 is fixedly connected to the bottom end of the rotating plate 4.
[0026] In this embodiment, when the lifting plate 9 moves up and down, the lifting plate 9 moves upward along the outer wall of the guide rod 10. The setting of the guide rod 10 and the sliding hole 14 can serve the purpose of lifting and lowering guidance.
[0027] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
