Abstract
Description
Technical Field
[0001] This utility model relates to the field of ferrite magnet clamping technology, and in particular to a clamping fixture for ferrite magnet production. Background Technology
[0002] Ferrite magnets are magnetic devices made of ferrite materials. During the production of ferrite magnets, they need to be clamped by fixtures to facilitate operations such as cutting, drilling, and performance testing, thereby improving the quality of the ferrite magnets.
[0003] Patent specification CN221818463U discloses a high-efficiency positioning fixture for ferrite cores, including a base. The base has an adjustment mechanism on its bottom surface. The adjustment mechanism includes a threaded rod, with a fixing pad rotatably connected to the outer surface of the threaded rod. The fixing pad is fixedly connected to the bottom surface of the base. A threaded block is threadedly connected to the outer surface of the threaded rod, and a symmetrical connecting rod is hinged to the outer surface of the threaded block. This high-efficiency positioning fixture for ferrite cores, through the coordinated arrangement of the base, adjustment mechanism, and forward / reverse motor, allows the device to be adjusted according to the length of the ferrite core to be inspected. This not only makes it extremely convenient for operators to use but also effectively expands the applicability of the device and significantly improves its practicality in real-world applications.
[0004] However, in implementing the relevant technology, the above-mentioned high-efficiency positioning fixture for ferrite cores has the following problems: the device uses a forward and reverse motor to drive two fixed boxes to move closer to each other to clamp the ferrite magnet, and a forward and reverse motor to drive several clamping claws to limit the ferrite magnet. This causes the ferrite magnet to be subjected to continuous squeezing force from the fixed boxes and clamping claws, which can easily lead to excessive squeezing force on the ferrite magnet and damage, thereby reducing the processing quality of the device. In view of this, a fixture for ferrite magnet production is provided to overcome the above defects. Utility Model Content

The third reversible motor rotates in both directions, moving the two baffles closer or further apart, allowing the spacing between them to be adjusted according to the size of the ferrite magnets without affecting the spacing adjustment function of the two limiting plates.

[0030] Working principle:
[0031] When using this invention, if it is necessary to clamp a ferrite magnet, the ferrite magnet is placed between the two limiting plates 5. The first reversible motor 2 rotates, driving the first bidirectional threaded rod 3 to rotate, thereby causing the two movable rods 4 to move closer together, which in turn causes the two limiting plates 5 to move closer together, clamping the ferrite magnet. The second reversible motor 7 rotates, driving the second bidirectional threaded rod 8 to rotate, thereby causing the four pressure plates 9 to move closer together, limiting the ferrite magnet. The first reversible motor 2 rotates in both directions, driving the first bidirectional threaded rod 3 to rotate in both directions, thus causing the two movable rods 4 and the two limiting plates 5 to move closer or further apart, making the distance between the two limiting plates 5 easy to adjust. The second reversible motor 7 rotates in both directions, driving the second bidirectional threaded rod 8 to rotate in both directions as well. This causes the four pressure plates 9 to move closer or further apart, making the spacing between the pressure plates 9 easy to adjust. This allows the device to stably limit the movement of ferrite magnets of different sizes. During the process of limiting the ferrite magnets by the limiting disc 5 and the pressure plates 9, the first soft pad 6 reduces the squeezing force of the limiting disc 5 on the ferrite magnets, and the second soft pad 10 reduces the squeezing force of the pressure plates 9 on the ferrite magnets, thus reducing the probability of damage to the ferrite magnets. At the same time, the two baffles 17 block the two movable rods 4, preventing them from moving closer, which in turn prevents the two limiting discs 5 from moving closer. This reduces the squeezing force of the limiting plate 5 on the ferrite magnet. The four limiting blocks 20 respectively block the four moving blocks 21, preventing them from getting closer, thus preventing the four pressure plates 9 from getting closer. This reduces the squeezing force of the pressure plates 9 on the ferrite magnet, further reducing the probability of damage to the ferrite magnet. The forward and reverse rotation of the third forward and reverse motor 12 drives the first bidirectional lead screw 13 to rotate in both directions, causing the two sliders 14 to move closer or further apart, which in turn causes the two connecting plates 15 to move closer or further apart, which in turn causes the two connecting shafts 16 to move closer or further apart, which in turn causes the two baffles 17 to move closer or further apart. This allows for adjustment of the two movable rods 4 and the two... The minimum spacing of the limiting discs 5 allows the spacing of the two baffles 17 to be adjusted according to the size of the ferrite magnet without affecting the spacing adjustment function of the two limiting discs 5. The forward and reverse rotation of the fourth forward and reverse motor 18 can drive the second bidirectional lead screw 19 to rotate in both directions, thereby causing the two limiting blocks 20 to move closer or further apart, thus adjusting the minimum spacing between the four pressure plates 9. This allows the spacing of the limiting blocks 20 to be adjusted according to the size of the ferrite magnet without affecting the spacing adjustment function of the four pressure plates 9, thereby improving the applicability of the device. This makes the device easy to stably limit the ferrite magnets of different sizes, while not easily damaging the ferrite magnets, thus improving the applicability and processing quality of the device.
