Description

Technical Field

[0001] This utility model relates to the field of magnetic ring processing technology, specifically a positioning fixture for grinding the inner ring of a magnetic ring. Background Technology

[0002] A magnetic ring is a ring-shaped magnetic conductor. Magnetic rings are commonly used anti-interference components in electronic circuits, effectively suppressing high-frequency noise. They are typically made of ferrite materials (Mn-Zn). Magnetic rings exhibit different impedance characteristics at different frequencies; generally, their impedance is very small at low frequencies, and increases sharply as the signal frequency rises.

[0003] The existing Chinese utility model patent with publication number CN208645162U discloses a magnetic ring positioning fixture, including a magnet, a cover, bolts, a spring, a connecting rod, a support frame, a base, a positioning plate, a substrate, and resin. The base plate of the workpiece is placed at the L-shaped corner of the positioning plate. Pressing the cover causes the magnetic ring of the workpiece to adhere to the magnet. Releasing the cover returns the spring to its original state, pushing the magnetic ring of the workpiece into the rectangular opening of the base plate. Adhesive is then applied at the contact point for fixation. The technical advantages are high installation accuracy, ensuring product consistency, and improving production efficiency.

[0004] The existing magnetic rings require grinding of both the inner and outer rings after processing to ensure they meet the requirements. When grinding the inner ring, the magnetic ring needs to be fixed. The original fixing device requires workers to align the inner ring of the magnetic ring with the grinding device to prevent misalignment from affecting the grinding effect. It is also impossible to fix magnetic rings of different sizes during grinding, resulting in poor performance of the fixing device.

[0005] Therefore, those skilled in the art have provided a positioning fixture for grinding the inner ring of a magnetic ring to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning fixture for grinding the inner ring of a magnetic ring, so as to solve the problem mentioned in the background art that the existing positioning fixture for grinding the inner ring of a magnetic ring requires the worker to align the inner ring of the magnetic ring with the grinding device during use to prevent the magnetic ring from being misaligned and affecting the grinding effect. In addition, it is impossible to fix magnetic rings of different sizes when grinding the magnetic ring, resulting in poor use of the fixing device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0024] Specifically, the device plate 1 is square in shape and has a hole 2 inside. The hole 2 is circular in shape. When the grinding device grinds the inner ring of the magnetic ring, the grinding debris of the magnetic ring falls through the hole 2 and is collected. The sliding groove 3 is slidably connected to the sliding block 13, which drives the widened plate 12 to slide. The mounting plate 4 is equipped with two push rods 5.

[0026] Specifically, the first positioning ring 6 and the second positioning ring 8 have the same structure. The diameters of the first positioning ring 6 and the second positioning ring 8 are set by using different magnetic ring diameters. When placing the magnetic rings, different magnetic rings are placed on different positioning rings according to their sizes. The alignment of the magnetic rings is confirmed by checking the outer edge of the positioning ring. The inner ring of the magnetic ring is then polished. The connecting plate 7 connects the first positioning ring 6 and the second positioning ring 8.

The widening of the first fixing ring 10 and the second fixing ring 16... A buffer pad 14 is installed on the inner side of the plate 12. The spring 15 is installed through the buffer pad 14. When the magnetic ring is fixed, the fixed ring is pushed inward by the push rod 5. The first fixed ring 10 and the second fixed ring 16 are moved between each other by the rebound force of the spring 15. When the first fixed ring 10 and the second fixed ring 16 move, they move in the sliding groove 3 through the sliding block 13. After the magnetic ring is fixed, the inner ring is polished. A drain hole 2 is opened in the center of the device plate 1.
