Description

Technical Field

[0001] This utility model relates to the field of multipole magnetic ring technology, specifically a dry-pressed ferrite multipole magnetic ring oriented device. Background Technology

[0002] Most current ferrite multipole magnetic rings have a hexagonal crystal system. After orientation, the c-axis (easy magnetization axis) of the unit cell in the ferrite multipole magnetic ring changes direction. During sintering, there is a significant difference in the shrinkage ratio between the c-axis and the direction perpendicular to the c-axis of the ferrite unit cell. The shrinkage along the c-axis is much greater than that along the direction perpendicular to the c-axis. This is manifested in the fact that after sintering, the circular surface of the toroidal preform will become an approximately polygonal shape.

[0003] A magnetic field press is an essential machine for producing multi-pole magnetic rings. The magnetic poles combined with the pressing block on the press can achieve magnetic orientation and shaping of magnetic powder. The distance between the magnetic poles can be adjusted by handwheel. However, manual adjustment is labor-intensive. Existing technology uses a servo motor to drive the transmission screw to rotate inside the screw hole, which in turn drives the adjusting seat to extend and retract inside the adjusting sleeve. This allows adjustment of the unfolded length of the magnetic pole body, and further adjustment of the distance between the first and second magnetic pole orientation mechanisms. However, in actual use, multiple bolts are required to fix the device, resulting in low efficiency and a lack of practicality. Utility Model Content

[0015] This invention has the advantage of facilitating the fixing and disassembly of the device. When the operator tightens a bolt, the bolt drives the gear on it to rotate via a slider. The gear drives the gear ring to rotate, which in turn drives multiple gears to rotate simultaneously. This, in turn, drives multiple bolts to rotate via sliders on the gears.

This solves the problem of low efficiency caused by the inconvenience of disassembly and assembly of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] See Figure 1-4A dry-pressed ferrite multipole magnetic ring oriented device includes two main body components 1; each main body component 1 includes a mounting shell 11 on which a magnetic pole body 12 is disposed; a mounting plate 13 fixedly connected to the outer wall of the mounting shell 11; bolts 14 threadedly connected to the mounting plate 13, and multiple bolts are disposed thereon; a linkage component 2 is disposed on the mounting shell 11, the linkage component 2 including: a sliding groove 21, each bolt 14 having a sliding groove 21 on its outer wall; a gear 22, each sliding groove 21 having a gear 22, and each gear 22 being rotatably connected to the outer wall of the mounting plate 13; a through groove 27, each gear 22 having a through groove 27; and a slider 23, each through groove 27 having a slider 23. A slider 23 is fixedly connected to each side wall; a gear ring 24 is rotatably connected to the outer side wall of the mounting plate 13, and each gear 22 meshes with the gear ring 24; a mounting ring 25 is fixedly connected to the outer side wall of the mounting shell 11; an auxiliary mechanism 26 is disposed on the mounting shell 11; the auxiliary mechanism 26 includes: a pressure plate 261, which is disposed on each bolt 14; a spring 262, which is disposed on each pressure plate 261, and both ends of each spring 262 are fixedly connected to the outer side wall of the pressure plate 261 and the outer side wall of the mounting ring 25 respectively; a telescopic shell 5 is disposed on each pressure plate 261, and each telescopic shell 5 is rotatably connected to the pressure plate 261.

[0027] When ready for use, the operator aligns multiple bolts 14 with the external threaded holes. Then, the operator tightens one bolt 14, causing it to rotate via the slider 23 in the through groove 27, which in turn rotates the gear 22 on it. The rotation of the gear 22 causes the gear ring 24 to rotate on the mounting plate 13, resulting in the gear ring 24 driving multiple gears 22 to rotate simultaneously. This, in turn, causes the sliders 23 on the gears 22 to rotate the multiple bolts 14. Simultaneously, the auxiliary mechanism 26 on the mounting ring 25 applies a force towards the mounting plate 13 to the multiple bolts 14, ensuring their stable entry into the threaded holes. The operator then proceeds with the installation... The orientation mechanism inside the shell 11 is used for the magnetic pole body 12, thereby improving the practicality of the device. When the bolt 14 moves, the spring 262 presses the pressure plate 261, so that the pressure plate 261 always fits against the bolt 14 and applies force to the bolt 14, ensuring that it can stably enter the threaded hole, thereby improving the stability of the device. When the spring 262 extends and retracts, it drives the telescopic shell 5 to extend and retract at the same time, and is rotatably connected to the telescopic shell 5 through the pressure plate 261, so that when the bolt 14 rotates, it drives the pressure plate 261 to rotate at the same time, avoiding the pressure plate 261 from rotating due to friction on the surface of the bolt 14, which would damage the spring 262, thereby improving the safety of the device.

[0028] Example 2

[0029] See Figure 1-4Based on Embodiment 1, auxiliary functions have been added;

[0030] Each of the slide grooves 21 has a limit block 6 fixedly connected to its inner sidewall; a protective shell 4 is fixedly connected to the outer sidewall of the mounting plate 13, and the gear ring 24 is rotatably connected to the inner sidewall of the protective shell 4; the width of the protective shell 4 is greater than the width of each gear 22.

[0031] When in use, as the slider 23 slides within the groove 21, the slider 23 cannot move further after the limiting block 6 contacts it, thus limiting the bolt 14 and preventing it from completely moving out of the gear 22, which would require reinstallation by the operator, thereby improving the stability of the device. The protective shell 4 completely covers the gear 22 and the gear ring 24, preventing the operator from being injured by the rotating gear 22 and gear ring 24, thus improving the safety of the device. When the gear 22 rotates, the protective shell 4 is thicker than the gear 22, thus preventing the gear 22 from rubbing against the inner wall of the protective shell 4 and affecting the normal rotation of the bolt 14, thereby improving the stability of the device.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
