Description

Technical Field

[0001] This utility model relates to the field of disc motor technology, specifically to an automatic cutting device for disc motor magnets. Background Technology

[0002] Magnets, as a key material, are widely used in the stator manufacturing of micro disc motors. They are typically made of lithium iron boron and are disc-shaped. Currently, most manufacturers use single-wire fast-wire cutting machines to cut the magnets in the production process of micro disc motors. However, this traditional equipment has significant limitations: firstly, a single-wire fast-wire cutting machine can only cut one magnet at a time, resulting in low production efficiency; secondly, during the cutting process, magnet repositioning can easily lead to uneven thickness of the cut magnets, thus affecting product quality and performance consistency. With the continuous growth of market demand and the increasing requirements for product precision, existing single-wire fast-wire cutting machines are no longer sufficient to meet the demands for efficient and high-precision production.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] See Figure 1An automatic cutting device for disc-type motor magnets includes a base 1, a lifting mechanism 2 mounted on the base 1, a lifting plate 3 mounted on the lifting mechanism 2, and multiple positioning frames 4 mounted on the lifting plate 3. Each positioning frame 4 is composed of multiple positioning plates 41 arranged at equal intervals, with cutting grooves 42 between the positioning plates 41. A U-shaped positioning groove 43 is formed on the top of each positioning plate. Columns 5 are mounted at the four corners of the base 1, and a base plate 6 is mounted on the top of each column 5. Multiple cutting mechanisms 7 are mounted on the base plate 6, with each cutting mechanism corresponding to one of the positioning frames 4. The device is used for cutting... Mechanism 7 includes a pair of rotating rollers 71, with short shafts 72 on the left and right sides of the rotating rollers 71. A driven gear 73 is sleeved on the outside of one of the short shafts, and a slip ring 74 is provided at the end of the other short shaft. The driven gear 73 is connected to the drive mechanism 8 for transmission, and the slip ring 74 is connected to the power supply. Bearing posts 9 are provided on the short shafts 72 and are fixed to the bottom of the substrate by the bearing posts 9. Multiple diamond wires 75 are provided between the rotating rollers 71, and the diamond wires 75 correspond one-to-one with the cutting grooves 42. The rotating rollers 71 and the short shafts with slip rings are made of conductive material. Specifically, the magnetic column is placed in the positioning groove 43 of the positioning frame 4. At this time, the drive mechanism 8 is turned on, and the driven gear 73 drives the rotating roller 71 to rotate. At the same time, the power is turned on, and the diamond wire 75 is energized through the collector ring 74, the short shaft 72 and the rotating roller 71. The lifting mechanism 2 is started, and the lifting plate 3 is lifted, which drives the magnetic column to rise. During the rise, the magnetic column and the diamond wire 75 rotate. The diamond wire 75 melts the part in contact with the surface of the magnetic column instantly through the current. The rise continues until the diamond wire cuts the magnetic column into multiple circular pieces, improving production efficiency and product quality. The positioning frame 4 is preferably arranged in a cross shape, and the cutting mechanism 7 is also arranged in a cross shape to avoid mutual interference.

[0016] In this embodiment, the lifting mechanism 2 includes a lifting cylinder 21 and multiple guide telescopic columns 22. The lifting cylinder is located at the center of the base, and the guide telescopic columns are located at the four corners of the base. The lifting cylinder 21 lifts and lowers the lifting plate 3, and the rising action, combined with the diamond wire 75, cuts the magnetic column. The guide telescopic columns 22 improve the stability of the lifting.

[0017] In this embodiment, the drive mechanism 8 includes a drive motor 81, and a drive gear 82 is mounted on the output shaft of the drive motor 81. The drive gear and the driven gear are connected by a belt for transmission. After the drive motor 81 starts, it drives the driven gear to rotate through the drive gear 82 and the belt, thereby driving the rotating roller 71 to rotate, thus realizing the cutting.

[0018] In this embodiment, an annular groove 76 is formed on the rotating roller 71, and the diamond wire 75 is located within the annular groove 76. The annular groove 76 limits the diamond wire 75, ensuring the accuracy of the cutting position.

[0019] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
