Description

Technical Field

[0001] The utility model relates to the field of magnetic core cutting jigs, in particular to a micro-columnar magnetic core cutting jig. Background Art

[0002] The micro-columnar magnetic core cutting jig is a specially designed auxiliary tool used to accurately cut a larger columnar magnetic core into multiple micro-columnar magnetic core segments. It ensures accurate positioning of the magnetic core and a flat cutting surface during the cutting process, thereby improving work efficiency and supporting mass production requirements.

[0003] However, for existing micro-columnar magnetic core cutting jigs, such as a micro-columnar magnetic core cutting jig with the patent number "202021835435.5", it includes: a jig body; a placement position for placing the columnar magnetic core, the placement position is arranged inside the jig body, the number of placement positions is set to be multiple, and the multiple placement positions are arranged longitudinally and evenly in sequence; a cutting hole, which is in a long strip shape, the cutting hole is horizontally arranged on the jig body, and the cutting hole communicates with the placement position. By placing multiple columnar magnetic cores in multiple placement positions and corresponding to the cutting position through a cutting device, the columnar magnetic core is cut into multiple segments to obtain micro-columnar magnetic cores, ensuring the cutting accuracy, improving the workpiece quality, and having high work efficiency and being able to complete mass production. However, this patent still has relatively obvious defects. For example, the first jig body and the second jig body are of the same size, so it is more troublesome to buckle the first jig body and the second jig body, and alignment is required during buckling. At this time, it may lead to that this process may be relatively complex and time-consuming. Especially in the process of mass production, alignment errors are inevitable, which may cause inaccurate cutting and thus affect the product quality. In addition, if the jig is operated improperly during alignment, or due to frequent buckling and separation, the placement position and cutting hole of the jig may be accelerated in wear due to friction. This kind of wear will not only affect the cutting accuracy, resulting in inconsistent product sizes or shape deviations, but also may shorten the service life of the jig, increase production costs and maintenance difficulties. Therefore, it is necessary to improve the design of this jig to simplify the alignment process, improve the stability of buckling, and enhance the wear resistance of the jig. Summary of the Utility Model
