Description

Technical Field

[0001] The present application relates to the technical field of chamfering equipment, and in particular to a chamfering device for tile-shaped products of rare earth permanent magnets. Background Art

[0002] The rare earth family is a group of 15 elements from the lanthanide series, plus scandium and yttrium, which are closely related to the lanthanide series, totaling 17 elements. They are: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, and yttrium. One of the important functions is permanent magnetism. The so-called permanent magnetism does not mean that it can always maintain its original magnetic state without changing, but its magnetism is relatively stable and its decay cycle is relatively long. The largest user of metallic neodymium is neodymium iron boron permanent magnet material. Neodymium iron boron magnets have high magnetic energy product and are called the "king of permanent magnets" in the contemporary era. They are widely used in electronics, machinery and other industries for their excellent performance. At present, after the rare earth permanent magnet ferrite magnetic tile is pressed and formed, it is necessary to use a chamfering device to chamfer the inner and outer arcs of the magnetic tile to eliminate the sharp parts on the magnetic tile and reduce the defects of the magnetic tile. After searching, the patent document with the authorization announcement number CN220463275U announced a device for automatically chamfering the inner and outer arcs of a tile-shaped product of a rare earth permanent magnet, including a workbench, the surface of the workbench is fixedly connected to a guide rail, the surface of the workbench is fixedly connected to an upper pressure conveyor belt, and the surface of the workbench is connected to a sand plate through an adjustment mechanism. The utility model relates to the technical field of rare earth permanent magnets. The device for automatically chamfering the inner and outer arcs of a tile-shaped product of a rare earth permanent magnet drives the sand plates around to shrink or expand synchronously by rotating the threaded rod until the sand plates move to the position required for the chamfering size, starts the rotating motor to drive the rotating cross plate to rotate, the rotating cross plate drives the sand plate to rotate through the sliding block, starts the upper pressure conveyor belt to drive the tile-shaped product to move, and when the tile-shaped product contacts the sand plate, the sand plate grinds and chamfers the product, thereby realizing fully automated feeding and chamfering, with good chamfering consistency, which is conducive to mass production, and the chamfering size can be adjusted according to actual conditions.

[0003] In actual use, it was found that the above scheme still has at least the following shortcomings: the method of clamping and fixing the rare earth permanent magnet tile-shaped product by utilizing the force generated when the spring is squeezed is not firm and stable enough; during the chamfering process, the rare earth permanent magnet tile-shaped product is prone to displacement, resulting in the deterioration of the quality of the chamfering process of the rare earth permanent magnet tile-shaped product. Therefore, we propose a chamfering device for rare earth permanent magnet tile-shaped products to solve the above problems. Utility Model Content

[0027] Through the above structure, the chamfering device for the rare earth permanent magnet tile-shaped product provided by the present application can achieve the effect of firmly and stably clamping and fixing the rare earth permanent magnet tile-shaped product 3 when in use.

The third motor 30 rotates forward or reversely, and the third motor 30 drives the connecting shaft 25, the connecting arm 26, the fixing plate 27, the second motor 28 and the grinding sand disc 29 to rotate, so that when the grinding sand disc 29 rotates to the tilt angle required for the chamfering size, the third motor 30 is stopped. According to the above operation steps, the other grinding sand disc 29 can be rotated and adjusted to the tilt angle required for the chamfering size, and then the two second electric telescopic rods 22 are controlled to extend and operate in sequence, so that the two grinding sand discs 29 can be adjusted to the height position required for chamfering respectively, and then The two second motors 28 are controlled to operate, and the two grinding sand discs 29 can be controlled to rotate.

Then, the two longitudinal electric slides 19 are controlled to move horizontally and longitudinally (i.e., move forward or backward) on the corresponding longitudinal electric guide rails 18, respectively, so that the two grinding sand discs 29 can be used to simultaneously perform chamfering processing on the two side edges of the rare earth permanent magnet tile-shaped product 3;

[0028] When the other two sides of the rare earth permanent magnet tile-shaped product 3 need to be chamfered, first control the two horizontal electric slides 21 to slide horizontally on the corresponding horizontal electric guide rails 20, so that the two grinding sand discs 29 are away from each other to a suitable distance, and then control the first motor 6 to rotate forward or reverse, so that the clamped rare earth permanent magnet tile-shaped product 3 can be controlled to rotate horizontally around the output shaft of the first motor 6. When the other two sides of the rare earth permanent magnet tile-shaped product 3 are rotated to face the corresponding grinding sand discs 29, stop the operation of the first motor 6, and according to the above-mentioned operating steps, the two grinding sand discs 29 can be readjusted to the inclination angle and height required for the chamfering size, and the other two sides of the rare earth permanent magnet tile-shaped product 3 can continue to be chamfered.
