Description

Technical Field

[0001] The utility model belongs to the technical field of annular magnet positioning, in particular to a positioning structure for annular magnet processing. Background Art

[0002] The components inside the magnet are iron, cobalt, nickel and other atoms. The internal structure of the atoms is quite special and they have magnetic moments. Magnets can generate magnetic fields and have the characteristics of attracting ferromagnetic materials such as iron, nickel, cobalt and other metals. Magnets can be divided into many categories according to their shapes, among which round magnets have a wider range of applications.

[0003] At present, a positioning mechanism is required to fix the annular magnet during processing. For example, Chinese utility model CN211889917U discloses a circular magnet center positioning processing device. By installing a support column and a rotatable positioning rod, similar to the principle of a compass, when the processing position of the circular magnet needs to be changed, it is only necessary to rotate the positioning rod to change it, and the distance from the changed position to the center position can be kept consistent, which effectively improves the processing accuracy, and when the distance from the center point needs to be changed, it is only necessary to change the angle of the positioning rod in the vertical direction, and there is no need to remove the circular magnet and reinstall it, which is convenient and fast, saving time and effort. By installing an automatically retractable positioning rod, when the angle of the positioning rod in the vertical direction is changed, the positioning rod can automatically extend and re-fit with the processing table, avoiding the situation where the positioning rod is not long enough to install the circular magnet on the processing table, and having good practical effect, by installing a plurality of fixed pressing plates with springs, when the circular magnet is initially installed, it is only necessary to make the fixed pressing plate support the inner groove of the circular magnet to complete the installation, which is convenient and fast to install, and the fixed pressing plates in multiple directions can effectively improve the fixing effect of the circular magnet.

[0004] Although the above-mentioned prior art can fix the annular magnet, when the annular magnet is rotated during processing, the annular magnet can only be rotated around the support column, and the annular magnet cannot be rotated at a fixed position so that different surfaces face the processing personnel, which makes processing extremely inconvenient.
